Every
day on Hawaii Island we cherish how great we feel when wake up in the
morning. It is a special type of joy to
awaken to the sounds of tropical birds, the smell of flowers, and the
sight of a brilliant sunrise.
We
were recently reading a book called Your Brain On Nature: The Science of Nature's Influence on Your Health, Happiness and Vitality that
details research that explains why we sleep so well and feel so great when we
wake up on Hawaii Island. We specify
Hawaii Island because many of the attributes are unique to Hawaii Island.
We go to sleep with a very dark sky.
Hawaii Island is careful to control light pollution in
support of the optical telescopes on Mauna Kea. There are lighting
ordinances that require shielded light and limited street lights. On
cloudless nights, the bright stars are visible above when we fall asleep at
night. According to Dr. Selhub, research shows that artificially
brightened night skies interfere with the sleep cycle by affecting melatonin
production and that even low levels of light during the night can interfere
with normal adult brain cell structures. Our very dark night sky helps us get
into a deeper sleep.
At night we hear calming sounds of nature.
We keep our windows open and can hear the wind blow
through the palm trees as we fall asleep. A Japanese research team at Chiba
University showed that sounds of nature, like the sound of a creek, changes the
brain blood flow to a state of relaxation. A study from Stockholm University
showed that nature sounds calmed people down whereas road traffic noise
increased stress based on measurable physiological markers. We don’t have noise from traffic or machinery
where we live. We didn't realize how quiet it was until we spent some
time in Honolulu last year and were unsettled by the constant background drone
of traffic, AC, and machinery spiked with loud sirens all night long.
We wake up to a symphony of tropical birds songs
Every morning the birds start to sing as the sun is
rising. Research published in Psychological
Medicine in 2006 showed that hearing birds songs in the morning lifts the
mood and decreases fatigue.
Blue light shines through our windows at sunrise
Early
morning light has more blue spectrum. The eye is very sensitive to the blue color (460nm) and causes the brain
to wake up, increase alertness, and boost concentration. Researchers at the University of Greenwich showed that blue light made people
happier, more alert, and more productive. The blue spectrum declines the
most in the winter compared to other spectrums, but in Hawaii we do not lose
our blue spectrum light in the winter.
We
breathe fresh air and negative air ions.
Breathing
in negatively charged air ions, most prevalent in the morning, has been shown
to improve health. Dr Selhub cites research that shows
negative air ions reduce stress, depression, anxiety, and improve cognitive
performance. Negatively charged ions are
depleted by pollution, electronic devices, and in enclosed places. Being near
the ocean with warm tropical rain, gives us plentiful negative air ions in
Hawaii.
We have aromas from flowers all year long.
We love having beautiful, tropical flowers around us all
the time. Research at Wheeling Jesuit
University found that the aromatic chemicals in flowers can increase alertness,
even in extremely small concentrations.
