Opening the door just a crack on a winter’s day my Comfort-o-meter, aka my nose, takes a reading of the wet and the cold outside. Anything below 40 degrees and beyond a light drizzle indicates a good day to curl up by the fire, which is where the cat and the dog are already. The forecast also includes the chance of a long winter’s nap. Unfortunately, the 24/7 work world doesn’t believe in naps, so we try to pretend that the seasons don’t really impact us. Beneath artificial lights, we push ahead at the usual breakneck pace despite cues from our body that maybe it would be good to slow down a little.
In winter, the outside world pulls in. Plants and animals suspend growth and go into a dormant state, waiting for a time when more sunlight and food are available. In the human world, however, mortgages, car payments, and work deadlines never sleep, so each day we rise in the dark, don our superhero tights, and head off to work, defying all odds and the laws of nature. There’s a price though. Too little sunlight and too much artificial light can lead to negative metabolism changes that in turn can lead to depression, heart disease, obesity, diabetes and certain cancers. Not enough UVB wears down our immune system making it easier to catch the flu and harder to get over it. It can make us sad, befuddled, and grumpy.
Sunlight infuses us with Vitamin D and nitrous oxide that helps with mood and metabolism. Sunbeams boost serotonin levels and suppress melatonin for more energy and a better frame of mind. Even on cloudy days some of that life-giving light is making its way into your body. However, if you live in the top half of the U.S. or in a particularly gray climate, you may need to supplement with Vitamin D tablets and/or a lightbox. And, it turns out, sleeping just a little more can do you a world of good too.
On the days I can’t convince myself that a jog in the rain or a walk in the snow is a good idea, I make myself at least stand on the front porch. Usually, something just beyond the porch entices me a little further – the neighbor’s dog, a bird, the garbage that needs taking out. Once off the porch, the whole sensory thing kicks in. I breathe a little deeper. The sting of the cold can feel refreshing – in small doses. The larger canvas of sky and trees and distant mountains stimulates my senses in a way a flat-screen never will. For just a moment, all the cares fall away, and I am glad to be alive on such a winter’s day.
