For many of us, once winter rolls around and the days get shorter, it can be difficult to drag yourself out from under the covers. Seasonal affective disorder comes on like a dark cloud to drag you down with feelings of hopelessness and despair. You wake up to darkness, and by the time you leave work, what little daylight there was in the afternoon is gone. People around you start to close up, hunching their shoulders and moving about with the sole intention of getting to where they’re going. What is it about this seasonal shift that shifts our mood so drastically?
Despite the cold, studies have shown that the temperature shift is not the main suspect for feelings of seasonal depression. It is instead the lack of daylight, more than the shift in any other atmospheric phenomena, which leads to feelings of depletion. Psychologist Mark E. Beecher of Brigham Young University conducted a study involving 16,452 adults that analyzed therapeutic distress across 19 weather and pollution variables over a six-year period. He found that seasonal increases in the amount of time spent in the sun were linked to decreased emotional stress—whereas temperature and pollution variables had no effect.
These results are surprising: One would think that weather, temperature, and pollution would have a profound effect on mood. Rainy days are often associated with sadness, however in the conducted study, this was not the case. The only variable which had any noticeable effect was the amount of sun time during the day.
Seasonal affective disorder can be debilitating. But Beecher’s findings are good news for anyone feeling emotionally and energetically depleted during the winter months. Rather than staying curled up in bed, which does seem enticing, your mood could conversely benefit from doing just the opposite. Getting exposure to sunlight, even if just through a window, has immense benefits on one’s emotional well-being. Taking a walk outside or meeting up with friends during daylight hours is just about the best thing for your mental state during the winter.
Happiness, Health, and Light
The correlation of light and mood is dependent on the body’s natural response mechanisms to produce serotonin, a neurotransmitter which helps to elevate the mood; and melatonin, a hormone which promotes sleep. When the body recognizes sunlight through the optic nerve, the gland in the brain which regulates melatonin slows its function, and serotonin levels increase. When light is diminished, the body increases the secretion of melatonin, and the secretion of serotonin is conversely slowed.
Being out in the sun is proven to make you healthier not just emotionally, but physically as well. It promotes healthier attitudes toward diet and exercise, and gives us the our dose of Vitamin D which can be hard to get from foods alone. Vitamin D promotes healthy cell and bone growth, reduces inflammation, and helps to stimulate immune function. Being exposed to the sun can lower blood pressure, create stronger bones and teeth, reduce the risk of breast and colon cancer, and can help to cure skin conditions including psoriasis and eczema. But don’t forget to protect your skin with sunscreen when you’re soaking up those rays!
Being in the sun also increases our vitality and energy. Richard Ryan, a psychology professor at the University of Rochester states that “research has shown that people with a greater sense of vitality don’t just have more energy for things they want to do, they are also more resilient to physical illnesses. One of the pathways to health may be to spend more time in natural settings.”
Just getting outside can do wonders for our health. Living in the developed modern world, it can be easy to forget our natural cycles and our most innate needs. We have synthetic lights, so we do not necessarily need to follow nature’s clock. Yet being in the presence of nature is so essential. It is inextricable from our being, and once we acknowledge this, there is bliss.
The Sufi poet Hafiz once wrote a poem titled “It Felt Love.” There’s a lot we can learn from it about our relationship with the sun. Light is the key to our innate flourishing souls. When we open ourselves up to receive the light, our beauty shines forth.
Did the rose
Ever open its heart
And give to this world
It felt the encouragement of light
We all remain
