2. Insomnia continues to be a major public health issue in the
United States. Recent studies found that approximately a quarter of
adults have grown frustrated with their sleep patterns, while up to
10% are diagnosed to have full-fledged insomnia.
According to the National Sleep Foundation, insomnia affects
quality of life, heightening the risk for depression and poorer overall
health. Long-term diseases such as cardiovascular problems and
diabetes are also common among insomniacs.
A growing body of research suggests that temperature
regulation plays an important role in facilitating better sleep among
people suffering insomnia. Experts explain that insomniacs tend to
have a warmer core body temperature than normal sleepers just
before going to bed, which causes increased sensitivity that leads
to sleep problems.
3. Importance of Temperature Regulation
The body’s heat distribution system, or thermoregulation
as medical practitioners would call it, has a significant link to
sleep cycles. During sleep, the body’s internal temperature
decreases to its lowest level, usually about four hours into
slumber. Scientists assume that a cooler bedroom may facilitate
better sleep because it simulates the decrease in body
temperature.
Studies showed that in general, the best temperature for
sleep is around 60 to 68 degrees Fahrenheit. Temperatures
above 75 degrees and below 54 degrees affects sleep, as it
induces feelings of restlessness.
The Matter of Relativity in ‘Comfort’
While turning down the thermostat can regulate body
temperature, there are still a lot of factors that come into play
when it comes to the matter of a comfortable night’s rest.
Research suggests that the level of comfort of the skin
temperature affects sleep and this factor varies from person to
person.
4. It depends, for example, on the sleeper’s choice of clothes and
beddings. Blood vessels in the skin narrow, trapping heat and increasing
core temperature, which can interfere with sleep if the bedroom is too
cold and the blankets are not thick enough.
Temperature regulation is important in creating an environment
conducive for sleep, but it entails many considerations. Nevertheless,
researchers suggest adjusting the thermostat to cooler temperatures,
around 65 degrees and adding sheets or clothes until the desired comfort
level is achieved.
