Is there a health benefit to cold temperatures? Do we need the change in temperature to stimulate the body and in turn develop a stronger immune system? Studies have shown that people actually think more clearly in the winter and are able to make more complex decisions. Glucose, which is important for brain function, is diverted more often in the summer in order to keep the body cool. The body’s metabolism actually burns more calories in colder weather in an effort to maintain a body temperature of 98.6. For those who suffer from allergies the winter provides an atmosphere in which the pollen count is almost non-existent. Core temperature drops when you sleep. This can take longer in the summer months which can limit the hours of deep restful sleep. Exercising in colder temperatures strengthens the immune system as well as your heart muscles, kills ticks and mosquitos as well as burns fat and makes you appreciate the warmth of your home. In spite of all this, I really love a hot summer evening.
