Who Loves the Sun? Mon, Jul 13, 2015
Hopefully, you enjoyed some sunlight this weekend. We are very fortunate to live in an area with abundant sunlight. While, in some situations, dark windowless environments might be suited for certain types of work, overall, the lack of exposure to sunlight can have negative health effects.
A team of researchers in Brazil found "...that a lack of exposure to natural sunlight in work environments could be associated with physiological, sleep, and depressive symptoms." The researchers studied twenty women in two different types of work environments for one week. Half of the women worked near a window and the other half did not. All of the participants wore an activity tracker that also monitored the amount of sunlight one receives. The "without window" group had elevated cortisol levels by 10 p.m., which were "correlated with minor psychiatric disorders and depressive symptoms" in the evenings. In addition, the women working without daylight also had lower melatonin levels at night, which were associated with "depressive symptoms and poor quality of sleep."
Keep enjoying some sunlight, with proper sunscreen of course, and have a great week!
