Spend time outside
Bundle up and head outside even it’s it cold. Just 30 minutes of natural sunlight at a time, ideally in the morning, will raise levels of the feel-good neurotransmitter in your brain called serotonin, studies show. Too little sunlight exposure can cause serotonin levels to dip, setting you up for symptoms of seasonal affective disorder.
Work near a window
If you don’t have a window near your office, walk past one whenever possible or take breaks to head outdoors. When the eyes see sunlight—even if you don’t glance up at the sky—the pineal gland, a small endocrine gland located in the brain, senses the increase in light and stops the production of the sleep-inducing hormone melatonin. Too much melatonin can make you feel sluggish, drowsy, and fatigued. Check out the upsides and downsides of sun exposure that you’ve probably never heard of.
