Sunlight and Serotonin.
We’re used to hearing about how too much of the sun’s warm rays can be harmful to your skin. But did you know the right balance can have lots of mood-lifting benefits?
Sunlight and darkness trigger the release of hormones in your brain. Exposure to sunlight is thought to increase the brain’s release of a hormone called serotonin. Serotonin is associated with boosting mood and helping a person feel calm and focused. At night, darker lighting triggers the brain to make another hormone called melatonin. This hormone is responsible for helping you sleep.
Without enough sun exposure, your serotonin levels can dip. Low levels of serotonin are associated with a higher risk of major depression with seasonal pattern (formerly known as seasonal affective disorder or SAD). This is a form of depression triggered by the changing seasons.
Sunlight and Mental Health.
Decreased sun exposure has been associated with a drop in your serotonin levels, which can lead to major depression with seasonal pattern. The light-induced effects of serotonin are triggered by sunlight that goes in through the eye. Sunlight cues special areas in the retina, which triggers the release of serotonin. So, you’re more likely to experience this type of depression in the winter time, when the days are shorter.
Due to this connection, one of the main treatments for depression with seasonal pattern is light therapy, also known as phototherapy. You can get a light therapy box to have at home. The light from the box mimics natural sunlight that stimulates the brain to make serotonin and reduces excess melatonin.
# Excess sun exposure is linked with increased skin cancer risk, don’t stay outside too long without sunscreen. If you’re going to be outside for longer than 15 minutes or so, you’ll need a sunscreen with an SPF of at least 15.
