Introduction
We often hear about the dangers of sunlight, but what about the dangers of too little? Although sunlight can negatively impact our health through sunburns which increase the risk of skin cancer, sunlight improves our mental health by increasing serotonin production, the “happiness hormone”; and by lowering depression, anxiety, and suicide risk.
Reasons
- Sunlight Lowers Depression Risk
A 2023 study found that spending the optimal amount of time in outdoor light—2 hours daily in summer, 1 hour daily in winter, and 1.5 hours a day on average—reduces risk of depression.
- Vitamin D Decreases Anxiety, Depression, and Suicide Risk
A 2021 study found that Vitamin D supplementation improved depression, anxiety, and sleep quality in women. Another 2023 study found a link between vitamin D deficiency and suicide risk. Finally, a 2008 study found a relation between vitamin D deficiency and depression. The findings of these studies suggest that sunlight, as a natural source of vitamin D, may play a crucial role in supporting mental health and reducing the risk of depression, anxiety, and even suicide.
- Sunlight and Serotonin Production
A 2013 study proposed that sunlight exposure could influence serotonin production, the “happiness hormone”, and therefore make us happier.
- More Sunlight, Better Mental Health
A 2023 study indicated a positive association between sunlight exposure and mental health.
Conclusion
Knowing how important sunlight is for your mental health, I urge you to take a break right now. Go outside. Soak up the sun. Your mind will thank you.
