According to Harvard Medical School, your body starts to drop in temperature just before you fall asleep. During sleep, the core temperature is lowered by 1 to 2 °F, as a way to conserve energy. Sleeping in a cooler room will help you get down to that level faster, helping you fall asleep (and stay that way) faster. Another way that keeping the room cool can improve sleep quality is by stimulating melatonin production.
It turns out that rooms with temperatures in the range of 60 to 68 degrees stimulate the production of melatonin, which promotes sleep. Sleeping in a colder room can improve sleep quality and even help you combat insomnia episodes. Scientists relate this to the fact that our body temperature drops naturally at night. Therefore, the rate of metabolism slows down and we spend less energy during sleep.
In general, the cold won't affect your sleep cycle, but it can make it harder to fall asleep and affect other aspects of your health. If you are too cold during sleep, your body can alter your cardiac autonomic response. Part of why sleep in a cold room is better because of how rest starts. The ideal temperature for sleep falls between 60 and 67 degrees Fahrenheit, and as you sleep, your body temperature drops naturally.
Introducing your body to a cooler environment helps stimulate sleep and allows you to cycle naturally during sleep stages. Why does the thermostat number matter? Our body temperature peaks and falls naturally over a 24-hour period, and the highest figures occur in the late afternoon and the lowest around 5 a.m. Sleep usually starts when our body temperature drops, so a colder room can encourage us to fall asleep sleep faster. With all that in mind, if you often have trouble sleeping, you may think that the solution is simple and straightforward.
Sleep well is vital for the body to function well, so it is very important to set the stage for a healthy sleep. Colleen Ehnstrom, a clinical psychologist with experience in treating insomnia and other sleep disorders. A study found that sleeping in a room at 66 degrees can help prevent certain metabolic diseases, such as diabetes. However, it is important to keep in mind that there are many different aspects involved in good “sleep hygiene”, with temperature being one of them.
The best temperature for sleep varies for each person based on personal health and comfort preferences, but research shows that sleep hygiene experts agree that it is too cold and too hot when it comes to nighttime temperatures. Sleeping fresh is definitely a must for a good night's sleep and provide your body with the environment it needs for real rest and regeneration. Sleep deprivation is one of the main causes of automobile and industrial accidents, making restless sleep a problem that affects more than just the individual. Melatonin is created in the pineal gland and released according to daylight to help you prepare for sleep.
Similar to the mood-enhancing effects of colder temperatures in the bedroom, you'll also find that better sleep reduces stress throughout the day. Temperature plays an important role in the functioning of the body and, even during sleep, the cold or heat you feel at night can influence the quality of the rest you receive.
