The best temperature for sleep. The ideal temperature for sleep is typically between 60°F and 67°F for most adults, says Martina Vendrame, M.D., neurologist and sleep medicine specialist at ...
How does temperature impact sleep? As a 2012 study explains, sleep and body temperature are intricately linked and impact each other. All humans operate on a 24-hour circadian cycle that affects ...
Normal human body temperature varies slightly from person to person and by the time of day. Consequently, each type of measurement has a range of normal temperatures. The range for normal human body temperatures, taken orally, is 36.8 ± 0.5 °C (98.2 ± 0.9 °F). [12]
This is why the temperature of your room should be in the 65-67 degree range at night, as sudden warming or cooling in your room can disrupt your sleep cycle (and potentially wake you up).
Skin temperature is the temperature of the outermost surface of the body. Normal human skin temperature on the trunk of the body varies between 33.5 and 36.9 °C (92.3 and 98.4 °F), though the skin's temperature is lower over protruding parts, like the nose, and higher over muscles and active organs.

Hyperthermia can set in when the core body temperature rises above 37.5–38.3 °C (99.5–100.9 °F). [3] [4] Humans have adapted to living in climates where hypothermia and hyperthermia were common primarily through culture and technology, such as the use of clothing and shelter. [5]
Ideal sleep temperature. For most people, keeping your bedroom cool — anywhere from 60 to 67 degrees, per the National Sleep Foundation — will likely result in higher sleep efficiency, or less ...
In humans, a diurnal variation has been observed dependent on the periods of rest and activity, lowest at 11 p.m. to 3 a.m. and peaking at 10 a.m. to 6 p.m. Monkeys also have a well-marked and regular diurnal variation of body temperature that follows periods of rest and activity, and is not dependent on the incidence of day and night ...
