Temperature Variations During your Day Can Make You Healthier Modern technology has succeeded in providing us with the most comfortable living environments possible. When we are cold, we put on the heat, when we are hot we turn up the air conditioner. Have all these luxuries spoiled us? Research has proven, this just might be the case. Previously, it was assumed that stable, comfortable fixed temperatures would create a well being of most people. However, new research has indicated quite the opposite. It has been found that temperature variations may indeed have a more positive effect on our health. It might even create pleasure and happiness.
How Temperature Variations Affect Your Health Studies are showing a correlation between temperature variations and preventable metabolic syndromes such as obesity, type 2 diabetes, and adrenal fatigue. The latest research has indicated that a person’s exposure to mildly cold or warmer environments that are outside their regular comfort zones can increase metabolism and energy usage, which in turn can tackle obesity. One study found exposure to mild cold temperatures over a 10 day period changed glucose metabolism and increased insulin sensitivity by more than 40%, aiding type 2 diabetes. Body temperature variations affect certain chemicals in the brainstem, which in turn increase sensitivity to GABA and adenosine. GABA, or gamma-Aminobutyric acid, is a neurotransmitter that blocks impulses between nerve cells in the brain. Low levels of GABA may be linked to anxiety or mood disorders. Adenosine is a neuromodulator, believed to play a role in promoting sleep and suppressing arousal. Adenosine also plays a role in the regulation of blood flow to various organs, a very important bodily function.
Temperature Variations Even Affect Sleep Is there an optimal sleeping temperature? Science says, yes. Research has been conclusive that body temperature variations most definitely affect sleep. They cause certain chemicals to be released into the brain that induces a sleepy and relaxed state. People who have a greater sensitivity to the fluctuation are heavy sleepers, while those who have less of a temperature variation reaction are lighter sleepers. The other known cause of increased body fluctuations other than temperature is exercise. For optimal sleep, the bedroom should be between 60 and 67 degrees Fahrenheit. It has been noted at temperatures above 75 and below 54 are disruptive to most people’s sleep. Your body naturally peaks and declines in temperature on its own. The highest levels are early in the afternoon, and the lowest is around 5 a.m. When your body starts to lose heat from its core, you experience feelings of tiredness. Colder temperatures help get the body to that lower temperature faster, thus enabling a deeper sleep. There are many benefits of sleeping in cold temperatures that can enhance your health: 
A lower temperature can help you fall asleep faster and sleep better. If your environment is too hot or too cold, your body will waste a lot of energy trying to regulate itself, resulting in
