Sunlight and your Mood
By: AGelbert Date: December 19, 2014, 7:21 pm

Remember, dear readers in the northern hemisphere, that you are
sunlight deprived this time of year. That is a BIG DEAL for we
Homo SAPS in regard to mood.

Effect of sunlight and season on serotonin turnover in the
brain.

Abstract
Alterations in monoaminergic neurotransmission in the brain are
thought to underlie seasonal variations in mood, behaviour, and
affective disorders. We took blood samples from internal jugular
veins in 101 healthy men, to assess the relation between
concentration of serotonin metabolite in these samples and
weather conditions and season. We showed that turnover of
serotonin by the brain was lowest in winter (p=0.013). Moreover,
the rate of production of serotonin by the brain was directly
related to the prevailing duration of bright sunlight (r=0.294,
p=0.010), and rose rapidly with increased luminosity. Our
findings are further evidence for the notion that changes in
release of serotonin by the brain underlie mood seasonality and
seasonal affective disorder.

IT REALLY IS THIS SIMPLE
In the medical world…
If it can’t be patented and make someone billions of dollars a
year (literally), you’ll never hear about it.
Here’s a powerful healing strategy that helps with cancer, heart
disease, diabetes etc. and countless other conditions.
It won’t cost you a cent, it has no risk and your doctor will
never tell you about it (assuming he even knows about it which
he probably does not.)
Go to bed early, when the sun goes down, and sleep in absolute
dark.
It’s that simple.

[font=times new roman]Abstract[/font]
The purpose of the present studies using artificial light was to
determine how the timing and duration of exposure influence the
light-induced suppression of pineal melatonin levels in
hamsters.
An 8-min exposure to 0.186 microW/cm2 of cool white fluorescent
light caused a continued depression of pineal melatonin even
when animals were returned to darkness. In addition, the pineal
gland does not appear to change its sensitivity to light
throughout the night. A 20-min exposure to 0.019 microW/cm2 of
cool white fluorescent light did not significantly suppress
pineal melatonin during any time of the melatonin peak, whereas
a 20-min exposure to 0.186 microW/cm2 was capable of always
suppressing melatonin.
Furthermore, increasing the duration of 0.019-microW/cm2
exposure to 30, 60, 120, or 180 min does not increase the
capacity of this irradiance to depress melatonin. 👍
Similar to artifical light, natural light has a variable
capacity for suppressing nocturnal levels of pineal melatonin.
Twilight irradiances of 0.138 microW/cm2 or less did not
suppress nocturnal melatonin whereas twilight irradiances of 3.0
microW/cm2 or greater did suppress pineal melatonin. A few
animals did have lower melatonin after a 40-min exposure to full
moonlight during July (0.045 microW/cm2) or January (0.240
microW/cm2).
However, pineal melatonin levels remained high in the majority
of animals exposed to [img

Agelbert NOTE: In regard to light mediated melatonin production
or suppression, we are just like hamsters. If you wish to avoid
suppressing your melatonin levels at night, you need to get some
sort of night lighting that lacks blue wavelengths. Regular
electric lighting in your home contains blue light. Blue light
will trigger melatonin supppression, which will degrade the
quality of your sleep. 👎
For better sleep, you need to avoid the wavelengths that do not
trigger melatonin suppression. A night light with little or no
blue light is the way to go. 🌜👍
Nobody sells lights by microwatt/square centimeter ratings, so
the above study does not help in shopping for these lights.
Also, searching for lights by lux level (light intensity) is not
the way to shop for these lights either. In the above study, the
unit they used (microwatt/square centimeter) is a measure of
energy absorbed, which converts to lux poorly because there is a
lux (light intensity, not energy absorbed) formula for
microwatt/square centimeter to lux for every wave length in the
light spectrum. :P
So, rather than try to shop for LED lights by lux, just search
for LEDs without blue light (380nm to 500nm wavelength). You
need blue light when you are awake. It helps you remain alert.
But, blue light triggers the suppresion of melatonin production.
So, you need to avoid blue light when you want to sleep.
Below is an example of products you can buy to eliminate blue
light in your home at night. I've never bought anything from
them. I just found them with a quick search. I'm sure there are
many other places to buy products like these: 8)
