As if this weren’t compelling enough, a recent study showed that low vitamin D levels from sun avoidance increase all-cause mortality (R).
Studies published in the 70’s showed that part of the brain (the hypothalamus), the suprachiasmatic nucleus (SCN), functions as the core circadian pacemaker in mammals.
Getting enough sunlight during the daytime is essential for good sleep.
Getting enough light increases night-time melatonin levels (R). Humans are most sensitive to light stimuli during the night.
The safest way to prevent these risks is to actually get sun.
In southern Sweden, there was a 2X increased risk of dying among those who avoided sun exposure compared with the highest sun exposure group (R).
A tan is simply the body’s way of protecting itself from the power of the sun’s rays (R).
However, in reality, today’s science tells us that exposure to the ultraviolet radiation (UVR) in sunlight has many beneficial effects on human health.Indeed, most people are aware of the impact of sun exposure on Vitamin D production, which is a very important factor.However, there is a host of other health benefits that have been overlooked in the debate over how much sun is necessary for optimal health.Circulating vitamin D levels provide a surrogate measure of sun exposure and that it is the other molecules and pathways induced by sun exposure, rather than vitamin D-driven processes, that explain many of the benefits often attributed to vitamin D (R).Therefore, if you take vitamin D, you won’t prevent many of the risks associated with lower vitamin D.
