A bedroom temperature of around 65 degrees Fahrenheit (18.3 ℃) is ideal for the sleep of most people, assuming standard bedding and clothing. This (a) surprises many, as it sounds just a little too cold for comfort. Of course, that specific temperature will vary depending on the individual in question and their gender and age. But like calorie recommendations, it's a good target for the average human being. Most of us set bedroom temperatures higher than are ideal for good sleep and this likely contributes to (b) lower quantity and quality of sleep than you are otherwise capable of getting. Lower than 55 degrees Fahrenheit can be harmful rather than helpful to sleep, unless warm bedding or nightclothes are used. However, most of us fall into the (c) opposite category of setting a controlled bedroom temperature that is too high: 70 or 72 degrees. Sleep clinicians treating patients who can't sleep at night will often ask about room temperature, and will advise patients to (d) raise their current thermostat set-point by 3 to 5 degrees from that which they currently use.

  Anyone disbelieving of the influence of temperature on sleep can explore some related experiments on this topic. Scientists have, for example, gently warmed the feet or the body of rats to encourage blood to rise to the surface of the skin and release heat, thereby decreasing core body temperature. The rats fell asleep far (e) faster than was otherwise normal.
