NYSL Promotions Shares Scientific Evidence that Humans Need Sunshine to Thrive

At NYSL Promotions, we value the health and well-being of everyone on our team. We often engage in research to see what the latest studies have to say about how best to incorporate healthy habits into the life of a busy professional. One such study that we found intriguing was recently conducted in Brazil, where the effects of sunlight (and lack thereof) on physical health and mental well-being were monitored.

For this experiment, scientists observed 20 women while at work for a week. Half of these women worked in office space that had a window, while the other 10 did not. Participants wore an activity watch that monitored the amount of sunlight they received during the day, along with their movement level.

Also, through a saliva swab, the scholars tested both melatonin and cortisol levels in the women for the week of the experiment. Melatonin is a hormone that influences sleep habits, and the level of cortisol in the bloodstream is linked to the level of stress a person feels. To verify the findings of these biochemical investigations, psychiatric evaluations and sleep tests were ordered as well.

The results of the experiment served to verify what many already believe to be true. The group that lacked sunlight during working hours had higher cortisol levels and lower melatonin levels, and reported getting less sleep while being under more stress.

In our modern age of cozy cubicles this is alarming news indeed. If you’re feeling sun-deprived, we at NYSL Promotions recommend getting outside for a walk during lunch, or sneaking in sunshine breaks. You’ll feel less stressed, and you’ll sleep better at night as well.
