Our modern world affords us the comfort and luxuries of central temperature control, artificial light, and a grocery store full of food from all over the world any time of year, but in the Northeast and other geographical locations with extreme seasonal fluctuations, it is nearly impossible not to be effected by environmental signals. Even in climates that experience less dramatic change there is always some shifting from season to season that influences day to day life. Regardless of our efforts to keep comfortable, our body systems, neurotransmitters, and DNA hold the intelligence of the ages and cannot be easily fooled by contemporary technological environmental management. When we live in a Northern climate the deep, darkening of Winter is difficult to refuse, try as we may. No matter how we may attempt to keep warm and avoid the impact of lack of sunlight, most of us still experience the effects of long nights, cold winds and the isolation that comes along with not wanting to leave the house and go out in the cold any more than necessary.
