Find Your Super Power and Build Upon It

Nikken held its annual Leadership Summit on December 10 and 11 this year. Guest speaker Antoine Zervudacki, CEO of Letsmake Innovation and a Nikken collaborator, spoke about the need for change and sustainable growth in management. He described four archetypes for transformative leadership; in reality, these archetypes may pertain to anyone in pursuit of self-development. We may see ourselves in each archetype or in one specifically.

The Visionary is always looking to the future. This archetype specializes in defining strategic vision, guiding teams and inspiring colleagues to action. The Visionary transforms with special powers of communication. Areas to work on include staying connected to day-to-day realities, teamwork skills and focusing on details.

The Insighter has ears and eyes open to opportunity. This archetype focuses on the client and specializes in research, trends, market expectations, data, deep analysis and nurturing intelligence in teams. The Insighter is gifted in understanding complex situations and turning them into opportunities but may need to learn how to be flexible when change is needed and to pay more attention to teamwork.

The Maker embodies hands-on energy and focuses on generating results through effective processes. This archetype specializes in managing projects, improving procedures and meeting collective objectives on time. The Maker knows how to solve problems in a timely manner and to create success out of failures. Due to a passion for achievement, the Maker needs to balance personal and professional lives as well as those of the team and try not to deviate from long-term strategies.

The Humanizer has a heart that beats for people. This archetype specializes in building trust, empowering team members, communicating transparently and transforming strengths into a winning advantage. Conflict resolution is a major strength while strategic dimensions and solid use of data are areas for growth.

We are constantly transforming as we practice Active Wellness, develop into Humans Being More and share the benefits with the Global Wellness Community. It’s definitely an adventure to explore the archetypes we embody in our changing roles as students, teachers, parents, children, artists, entrepreneurs, inventors, engineers and so much more. Let’s tap into our super powers and make 2022 the best year it can be!

Why We Wear Jewelry

Jewelry was an early form of decorative art. The study of some primitive cultures shows that organic materials were used in the past. It was not until a later stage of human development that people chose precious and possibly scarce materials from far away to create jewelry.1

In many cases, jewelry was used as personal adornment, and also to convey the wearer’s social roles. Jewelry was also used to ward off disease and other evils, and sometimes even to work “magic” against opponents. In religious rituals, jewelry enhanced acts and signs of prayer and devotion to divinities.2

Jewelry that was made out of precious materials surfaced 5,000 years ago. In Mesopotamia, jewelry was fashioned from metals designed as leaves, spirals, and bunches of grapes and inlaid with brightly colored stones. The Ancient Chinese had high regard for jade and silver. Brooches made of precious metals were used in Ancient Greece and Rome to clasp clothes together. Mayan jewelry was generally made from jade, gold, bronze, silver, and copper. Gold was highly coveted in Ancient Egypt such as was displayed in artifacts from King Tut’s tomb. These ancient cultures considered jewelry as a status symbol and only the affluent wore it. In the Middle Ages, royalty and nobility wore jewelry made from gold, silver, and precious gems, while those from the lower classes wore ornaments made from base metals like copper and pewter.3

As times and traditions changed, the mindset about jewelry has also transformed. It has become a mode of self-expression and creativity that’s not limited to costly metals and stones. Jewelry can now also be made from textiles, leather, plastic, glass, or crystal. Fashionable and luxury jewelry is worn by people from all walks of life. These days, people wear jewelry to reflect their mood, style, and individuality.

Kenko Jewelry is the Nikken line, and whether it’s a pair of earrings, a necklace or a bracelet, each piece incorporates magnetic technology, comfort and style. Kenko means health or healthy in Japanese, and as with every Nikken product, our jewelry is made with the purpose of enhancing the Active Wellness lifestyle. Through the end of the year, there is special holiday jewelry, ideal for gifting, in addition to our regular year-round items. Check out the Holiday Gift Guide and get them while they last!

Hydrogen Water, Mitochondria and Energy

The scientific community is now uncovering hydrogen water’s mechanisms of action, which are diverse. They refer to the potential for increasing antioxidant activity, inhibiting inflammation, modulating immune regulation and regulating autophagy, circadian rhythm and mitochondria.1 (Autophagy is the body’s way of cleaning out damaged cells in order to regenerate newer,healthier cells.) Each of these beneficial anatomical activities is believed to help boost overall energy levels and health.

Because hydrogen is such a small molecule, the lightest in the periodic table, it can more easily dissolve throughout the cells as compared with traditional antioxidants.2 Hydrogen has the characteristic of protecting nuclear DNA and mitochondria and can permeate biomembranes to help reduce the risk of lifestyle-related issues caused by oxidative stress.3 In other words, drinking hydrogen-rich water may improve our overall ability to function, which elevates our quality of life.

Mitochondria are specialized structures that perform various jobs inside cells. They’re membrane-bound with two different membranes. These membranes function for the purpose of the mitochondria, which is to generate most of the chemical energy needed to power the cell’s biochemical reactions.4 That means mitochondria are the powerhouses within our cells.

Energy is produced by the conversion of chemicals within the cell. These chemicals go through pathways to be converted. The process of conversion produces energy in the form of a small molecule known as ATP (adenosine triphosphate). Different cells have different amounts of mitochondria—depending on how much energy they require. For example, the muscles have a lot of mitochondria, as do the liver and kidneys and to a certain extent, the brain, which lives off the energy those mitochondria produce.5

What do these energy-producing mitochondria have to do with hydrogen water? Clinical studies on hydrogen-rich water show that it helps improve mitochondrial function.6 When the mitochondria are functioning at high or optimal levels, our energy levels are correspondingly high. An abundance of energy makes all the difference to how we feel. It impacts our moods, our activity levels, and in essence, creates a domino effect of Active Wellness. When we are energetic, we tend to be happier and more active. When we are more active, each internal organ (heart, liver, lungs, etc.) gets a workout, which helps fight oxidative stress.

There are ongoing clinical trials on the effects of hydrogen water. From enhancing athletic performance to alleviating muscle fatigue,7 from helping to fight metabolic syndrome8 (a condition characterized by high blood sugar, triglyceride levels and cholesterol) to positively influencing the gut microbiome,9 these research studies appear to support the use of hydrogen water for a variety of reasons, most of which relate to increasing antioxidant activity, helping to reduce inflammation and regulating our immune systems.

How Do You Celebrate the Holiday Season?

We light candles for many reasons and especially during the holiday season. Each culture has its own rituals for lighting candles, but most use them to celebrate and honor traditions. The ancient Romans in particular lit candles in their temples and spiritual spaces. The lighting of candles before a shrine as a show of respect is also common in Buddhist and Hindu traditions. In types of Christianity, votive candles are often used in this way and are also lit to represent prayer intentions.1

Nowadays, we light candles to set a romantic mood and to relax. Some people light candles throughout their homes for their different scents and the warm glow they radiate. We light and blow out candles on birthday cakes and make wishes—an old tradition steeped in the belief that smoke took one’s prayers to the heavens to be heard and answered.

During the holiday season, Jewish people light the Hanukkah menorah with nine candles, eight of which symbolize the “miracle of the oil” while the tallest middle candle is used to light the others. Also known as the Festival of Lights, Hanukkah annually celebrates the rededication of the temple. According to tradition, the Jewish warriors only had enough holy oil to light the eternal flame for one night when they entered the temple. Miraculously, that small bit of oil burned for eight days — the exact amount of time it took to press and consecrate more oil.2

Kwanzaa is a seven-day celebration where a candle is lit each night. There are three red candles on the right (representing the struggles of the past and present), three green candles on the left (representing a hopeful future), and one black candle in the middle (representing the skin color of people of African descent. The black candle is lit on the first night and each subsequent night of Kwanzaa, one of the other candles is lit, alternating from left to right. On the final night, all seven candles are lit, and children receive gifts.3

Many Christians celebrate Advent, which begins on the fourth Sunday before Christmas. During Advent, a horizontal evergreen wreath with four candles is hung. Beginning on the fourth Sunday before Christmas, a candle is lit each Sunday, signifying the wait for the birth of Christ.4

Diwali is the five-day Indian celebration of the power of light over darkness. Diwali was on November 4, 2021 but the actual dates change annually according to the Hindu lunar calendar. Diwali marks a time of wishes for the coming year, and candles are lit throughout the home and community to represent the power of light. Floating candles are sent out on the water to Lakshmi, goddess of wealth and prosperity.5

No matter how you celebrate the holidays, we wish you joy, Active Wellness and prosperity. For wonderful gifts, please take a look at the Nikken Holiday Gift Guide.

Feeling Thankful

We often hear advice such as, “Be thankful.” Or, “You should think of all the things to be grateful for.” “Just think how lucky you are.” The truth is, feeling thankful and thinking about it are two separate activities. We can be asked to think about it and we can choose to do so, but feeling grateful just comes over us.

Thinking about gratitude is intellectual—a mental exercise that is important to practice. It can help get us out of a bad mood and elevate our attitudes. When we think about gratitude, we choose to be grateful. When we choose to be grateful, we take a positive approach to living.

On the other hand, feeling thankful comes from the heart. It’s not something we do by choice. We simply give in to that warm, wonderful feeling. We may even shed a tear of joy or relief. Feeling thankful is a state of being that comes from within. External forces may enhance it or decrease it, but the source is in our hearts, or in some cases, our stomachs. We talk about the flutter in our hearts when in love and the knot in our stomachs when in fear. Neither is something we choose; they are feelings that overwhelm us. That is how feeling thankful works, too.

During the Thanksgiving season, we consciously gather with friends and family to share our communal gratitude. We feel thankful for friends and family year-round, but the holidays seem to be designated times for verbalizing or showing our gratitude by actions. Not everyone celebrates in November and the timing really doesn’t matter. What matters is to set time aside to show those we are thankful for that we are grateful to have them in our lives.

At Nikken, this Thanksgiving we want to express how thankful we are to the members of our Global Wellness Community. We are thankful for your community spirit, your steadfastness, your loyalty and trust. At Nikken, we feel gratitude daily, weekly, monthly and as the years go by, we are humbled and awed that together we continue on our adventurous journey as Humans Being More. We continue pursuing Active Wellness and sharing an energetic lifestyle. We share how to build a Wellness Home with everyone we care about. From the heart, we thank you for being part of our community and helping it to grow. On Thanksgiving and every day, we give thanks to you.

Black Friday Then and Now

The true origin of the post-Thanksgiving Black Friday lies in the sense of black meaning “marked by disaster or misfortune.” In the 1950s, factory managers first started referring to the Friday after Thanksgiving as Black Friday because so many of their workers decided to falsely call in sick, thus extending the holiday weekend. About 10 years later, Black Friday was used by Philadelphia traffic cops to describe the day after Thanksgiving because they had to work 12-hour shifts in terrible traffic. Soon, the term caught on among shoppers and merchants in Philadelphia, and from there it took off nationwide.1

The 1980s brought the mythology of Black Friday as we know it today. While the phrases in the black and in the red are used in the business world to describe profits and losses, this explanation for one of the busiest shopping days of the year only came about in the 1980s, about 20 years after the phrase Black Friday was in regular use.2

In more recent years, global retailers have adopted “Black Friday” as the term and date to market their holiday sales. Here are some interesting facts about Black Friday:

  • Canadians often traveled over the border into the U.S. for Black Friday bargains. To curtail this, Canadian retailers began holding Black Friday specials of their own. The year 2012 saw the biggest Black Friday to date in Canada.3
  • Traditionally, Boxing Day had been considered the biggest shopping day of the year in the UK. In the 2010s, several American-owned retailers began to hold U.S.-style Black Friday promotions. As a result, more and more British retailers adopted the concept.4
  • In Welsh, Black Friday is known as “Dydd Gwener y Gwario Gwirion” (Silly Spending Friday).5
  • In Mexico, Black Friday was the inspiration for the government and retailing industry to create an annual weekend of discounts and extended credit terms. Known as El Buen Fin, meaning “the good weekend” in Spanish, it began in 2011. It takes place on November in the weekend prior to the Monday in which the Mexican Revolution holiday is pushed from its original date of November 20.6
  • In Germany, the term “Black Friday” was registered as a wordmark in December 2013. Black Friday GmbH is the exclusive licensee of the wordmark in Germany.7
  • Traditionally Black Friday is now a regular event in the U.S., Canada, United Kingdom, South Africa, Ireland, Australia, Germany, Italy, New Zealand, Africa, Benelux, Sweden, Brazil, Mexico and increasingly many other parts of the world.8

This year, as a way to express our gratitude, Nikken is offering Nikken Consultants and Registered Customers free ground shipping on all orders through December 17, 2021. Thank you from the bottom of our hearts.

Restful Sleep is So Sweet

Scientists don’t yet understand exactly why we need sleep so badly.  They believe it restores us physically and helps us organize things in our brain.1 We do know, however, that we can’t live an Active Wellness lifestyle without it. We cannot force ourselves to fall asleep, just as we can’t force ourselves to digest food more quickly or to eat as much as we want without gaining weight. In other words, we can’t control our sleep patterns; however, we can create the right conditions for sleep, both mentally and physically. That is, we can create good sleep habits for a pleasant sleep experience.

The study of sleep makes for fascinating science. Here are some interesting facts about other species:

• English bulldogs are the only canines known to experience sleep apnea, a breathing disorder. Their unusual airway anatomy (short snouts and underbites is the likely reason.2

• Sea otters hold hands when they sleep so they don’t drift away from each other.3

• Whales and dolphins literally fall half asleep. Each side of their brain takes turns so they can come up for air.4

• Trees go to sleep at night by relaxing their branches and perk them up in the morning.5

• Snails can sleep for three years.6

• Giraffes can get by on an average of 30 minutes of sleep each night.7

There are also intriguing facts about humans and our sleep patterns:

• We are the only mammals that willingly delay sleep.8

• Thirty minutes of exercise each day correlates with 14 minutes of extra sleep per night.9

• Parents of newborns lose about six months’ worth of sleep in their child’s first two years of life. Each additional child increases the mother’s loss of sleep by 46%.10

• Sleepwalking is most likely to occur between the ages of three and 17, with 15% of people thought to be sleepwalkers.11

• Women sleep longer than men. The reason is that women tend to multitask more than men; therefore, their brains work harder and take longer to recover.12

• We can dream in color or in black and white. About 12% are believed to dream exclusively in black and white.13 Today about 75% dream in color, while only 15% did before color television became available.14

Scientists used to think that everything shut down when we sleep, but over the last 60 years, they’ve discovered that our brains are very active while we sleep. In fact, some parts of the brain use more oxygen and glucose while asleep than when awake. The timing of our need for sleep is based on how long we have been awake and our body clock. For example, if we stay awake all night, we will feel more tired at 4 am than at 10 am.  Recent breakthroughs may have identified the gene that makes some people cope more easily with a lack of sleep.15

Sleep Can Be Your Superpower

To maintain an optimal level of Active Wellness, we can eat right, exercise regularly, use a good air filter and drink hydrogen water. Even more importantly, we need to sleep well and sleep enough! According to sleep and brain scientist Matt Walker, “Sleep is a non-negotiable biological necessity. Sleep is the Swiss army knife of health.” 1 Humans are the only species who intentionally deprive ourselves of sleep, creating the public health challenge of the century.

What are some of the benefits of getting a good eight hours of restful sleep? Matt Walker states that in studies of restful sleepers vs. sleep-deprived participants, the hippocampus in the brain shows significant memory signals in the good sleepers but not in the sleep-deprived. Here’s why:

  • Sleep prepares the brain for learning activities.
  • Sleep helps create permanent memories after learning.
  • Deep sleep acts like a transfer system for memories and learning.
  • Gene activities are impacted by sleep. Good sleep increases immune system activities, while poor sleep is associated with an increase in genetic stress activities and chronic inflammation.

Disruptions of deep sleep can impact brain functions, leading to certain dysfunctions. The good news is that scientists can now research ways to rectify this situation, as it is believed that sleep loss leaks into every aspect of physiology. Here are some tips for good sleep:

  1. Go to bed at the same time and wake up at the same time as regularly as possible. The body likes regularity and a fixed schedule. (This is why new mothers who are sleep-deprived or those who are on a split shift and can no longer adhere to a regular sleep schedule say they have “fuzzy” brains or “can’t think.”)
  2. Keep it cool. It takes a two to three degree drop in body temperature to fall asleep and stay asleep. 65º F or 18 Cº is generally ideal for most people.
  3. When you can’t sleep, get out of bed and preferably go to another room. The bed should be associated with sleep, not with tossing and turning.
  4. Go to bed only when sleepy.
  5. Turn off all electronic devices. In other words, don’t fall asleep with the TV on. Don’t have your mobile phone on and blinking and buzzing throughout the night.
  6. Stay away from alcoholic or caffeinated beverages before bedtime, preferably hours beforehand.
  7. Don’t take sleeping pills, unless prescribed by your physician. It’s easy to form a dependence on sleep aids, but it is not a natural way to go to sleep. We can retrain our bodies to rest naturally, but like any activity, it takes practice and patience.
  8. Invest in comfortable bedding. Make sure your mattress has the firmness that supports your comfort level.

Do You Know What Hydrogen Water Is?

Nikken introduced a new product during its annual Convention this past week: PiMag® PiDrogen Hydrogen Generator. It is a mini-generator accompanied by its own 16 fl oz / 475 ml glass bottle. The generator produces hydrogen-rich water that is rich in antioxidants and the glass bottle allows you to drink directly from it. The device is compact and lightweight, and produces 800-1200 ppb (parts per billion), the measurement of molecular hydrogen dissolved in water.

Easy to use, the generator cycles quickly within six minutes. An exclusive programmed control system shows the hydrogenating process with a blue light. When the water is fully hydrogenated and the cycle has finished, the blue light is replaced with a flashing red light. When the PiMag® PiDrogen water is ready for drinking, the red light will turn off automatically.

Hydrogen is the first and the lightest in the periodic table of chemical elements. Scientists use the periodic table to quickly refer to information about an element, like atomic mass and chemical symbol. The periodic table’s arrangement also allows scientists to discern trends in element properties, including electronegativity, ionization energy, and atomic radius.1

Hydrogen is a tasteless, colorless and odorless gas. When added to water, it becomes hydrogen water, hydrogenated water or hydrogenized water. Regardless of which naming convention is used, studies have shown that hydrogen water supports cellular energy production2 and provides antioxidant3 and anti-inflammatory properties4.

Oxidative stress occurs when we exercise too much, eat poorly and breathe in polluted air, get overexposed to UV rays and drink impure water—in other words, overexposure to free radicals result in the opposite of the overall feeling of well-being we experience when well-hydrated, well-rested and nutritionally-nourished. Hydrogen water helps combat oxidative stress with antioxidants, which are believed to neutralize the effects of free radicals.

How does adding hydrogen increase the benefits of PiMag water? PiMag water produced through any of the Nikken water filtration systems, filters out contaminants, then mineralizes and alkalizes water for a healthier, better tasting water than regular tap or bottled water. When you add hydrogen to PiMag water, the hydrogenated water actually helps reduce oxidative stress caused by an imbalance of free radicals and antioxidants in our bodies. In other words, hydrogen water tilts the balance in favor of antioxidants and makes PiMag water even more powerful.

In summary, the PiDrogen system transforms alkaline PiMag water into a source of highly concentrated dissolved hydrogen gas. When consumed, the water from the PiMag® PiDrogen supplies an abundance of antioxidants in order to assist in relieving oxidative stress and bringing the body back into balance, helping to maintain Active Wellness.

We invite you to try the PiMag® PiDrogen Hydrogen Generator. (Stay tuned for availability.)

Meaningful Activities Help Overall Well-Being

Buttoning a shirt. Tying shoelaces or a necktie. Scratching that hard-to-reach spot on the back. These are some of the things we may take for granted but are actually “meaningful activities” because they are everyday aspects of Active Wellness and impact the quality of our lives. Sometimes a life event might transform these everyday activities into goals.  Beginning in 2010, that’s what World Occupational Therapy Day celebrates every year on October 27: helping people across their lifespans to do the things they want and need to do through the therapeutic use of daily activities.1

We might not think about these daily activities until they’re hard to do. Finding ways for us to do them is what occupational therapists are concerned with.2 An occupational therapist will talk with us about our needs and goals. They’ll do tests to find out our strengths and challenges, then come up with a plan to reach our goals. This will include exercises and activities to strengthen our skills. While the word “occupation” usually means a job or profession, it can also refer to daily activities that let us live independently and bring meaning to our lives.

The World Federation of Occupational Therapists (WFOT) is the international voice of the profession and globally comprises 101 national organizations. World Occupational Therapy Day is the opportunity to promote their holistic approach to maintaining mobility throughout life. Occupational therapists focus on adapting the environment and/or task to fit the person, who is considered an integral part of the therapy team. It is an evidence-based practice deeply rooted in science.3

This year’s theme for World Occupational Therapy Day is “Belong. Be You.”4 OTs (as occupational therapists are known for short) do just that: help us belong in our Global Wellness Community by being ourselves, as purposeful participants in Active Wellness.
