Core body temperature is a key marker of the circadian rhythm, which controls human sleep and wake cycles. As nighttime approaches, the human core body temperature is at its peak for the day. While we sleep, the core body temperature drops a couple of degrees by morning and starts rising again once we wake up. The body reduces its core temperature by releasing heat through the extremities of the body. This transfer of heat is best accommodated in what is called a “Thermoneutral Zone”; a range of temperature near the body that allows the body to change its temperature unimpeded by the surrounding environment.
Researchers have defined this neutral temperature range to fall around 86°F. Studies show that near-body temperatures that are below 79°F or exceed 95°F can interrupt the body’s natural slow decrease in temperature by triggering the body’s defense mechanisms for heat and cold (sweating or shivering). This can in turn disrupt our sleep patterns by reducing our much needed Slow Wave Sleep and REM sleep. Additionally, it increases the number of awakenings we suffer over the night. Anyone who has woken up sweating or uncomfortably cold can relate to the reality of this problem. By near body temperature, we are talking about the temperature near the skin and often under covers, not necessarily in the room.
Additionally, the body undergoes a disadvantaged period of thermoregulation every time it enters REM sleep (about 5 times a night and mostly in the latter part of the sleep period). During this stage of sleep, the body does not regulate its temperature well, leaving us more susceptible to the effects of inappropriate ambient temperatures. Equipment that can help keep the body cool and shunt uncomfortable sweat away can not only facilitate our needed drop in core temperature; but, it can also keep the body dry and more comfortable through the night.
