these are a few articles about how our increasing indooor winter temp may be contributing to the obesity problem. it gives a basic understanding of brown fat and how higher temp central heating may be impacting us in a possible negative way. also, the last artivle talks about the energy savings that can be accomplished be lowing the indoor temp in the winter even a little bit.
remember, if you have it lower, it makes your body work more to keepyou warm, and it uses less money. it can be kept quite low and people wil still be fine. 30-40 years ago, the indoor temps in winter were much lower. some may be shocked at just how low. our indoor temp in winter during the day is 60 degrees. it drops to about 58-59 at night and upstairs is a little cooler. if you do decide to do this, DO NOT drop it fast. that will be hard on your body. start with a 2 degree drop every 2-3 days. your body will get used to it and your pocket book will be fuller too
