Light up your life

We have moved from a society, whose prehistoric ancestors worshipped the sun, to one that avoids it at great length. In the past, the sun was thought to have healing powers. Today, we know the harmful effects of its powerful UV rays on our skin. Avoiding the risk for skin cancer is a good thing. Avoiding sunlight altogether is harmful to our health.

Sunlight plays an important role in a variety of ways. It increases serotonin in the brain which improves mood. Have you ever noticed how irritable some people are in the winter, when sunlight is not as strong and we are confined to our houses? There is actually a diagnosis for this condition called Seasonal Affective Disorder (SAD), which is a disorder of the light-dark cycle. A well-lit room is great for the eyes, but it does not elevate serotonin in the same way. As we are confined to our desks, computers, paperwork and other indoor work, we are depleting those peace producing serotonin levels that affect our sleep, energy levels and appetites. Science has proven that depletion of this neurotransmitter is strongly associated with weight gain.

Sunlight directly affects your Vitamin D level, which is essential for bone health. This is especially important for women who are at risk for osteoporosis and for kids whose bones are still growing. Kids have such advanced play technology at their fingertips these days, that the appeal of playing outside has diminished. It’s no surprise then that the incidence of childhood obesity and depression has increased dramatically in the last decade.

It is not necessary to stay out in the sunlight for extended hours each day. In her book, Stop Gaining Weight, Dr. Laura Pawlak states, “It is estimated that the human brain requires, on average, one hour of bright light per day.” Take precautions to avoid sunburn, but get outside and soak up that sunshine. You will feel better for it.
