Sunlight Treats Depression

 

Sunshine in Arches National Park

 

Yes, it’s official now. Medically proven. Something we already knew…” sunshine on my shoulders makes me happy” as John Denver sang it, and we all feel better in the sunshine. With 70% of the U.S. under a blanket of snow this week,  a lot of people who are depressed could benefit with a trip to Phoenix,  The Valley of the Sun.

A recent study in the Archives of General Psychiatry shows that bright light treatment may improve depression. This was a double-blind, placebo-controlled randomized trial. (It doesn’t get any better than that!) 89 patients 60 years or older had better mood and better sleep just by being exposed to bright light for an hour every morning. After 3 weeks of treatment there was a significant improvement in the treatment group.

Light therapy affected hormone levels, with higher levels of melatonin in the treatment group. This hormone helps regulate circadian rhythm, which affects sleep cycles, among other things. Cortisol levels were lower, which is a hormone that is increased with higher stress levels.

Bright light is cheap! Going outside in the sun is even cheaper. Combining the sun exposure with a little exercise and some endorphin release is a great way for anyone to feel better, even if not clinically depressed. And since most people are vitamin D deficient, you’ll be boosting that vitamin level also. Kind of makes sense doesn’t it? Just don’t overdo it and get skin cancer. Maybe an hour of sun a day, will keep the doctor ( and the pills) away.

    After 2 no school “snow days” my 5 year old granddaughter was with spending Day #2 with us. We went into the living room and there she was. The sun finally had come out. She was next to the window and had her shirt pulled way up to her chin. The sun was shining on her chest and belly! I had to laugh and told her I could see was getting her vitamin D. She said “It just feels so good!” I immediately thought about how natural this was for her to expose as much of herself as she could to the sun’s rare rays here in Beardstown!

    Just thought it was worth sharing.

  2. Sunshine is one of the best things ever. It can’t cure depression. But it’s warmth I think can touch anyone. Today the sun shone and it was beautiful. http://greenleftyidealist.wordpress.com/2011/05/21/
