Disruptions in this stage can force you to try and catch back up, resulting in grogginess and a sense of being tired even if you feel you got enough sleep.

Body temperature affects not only sleep onset, but also sleep quality and the time spent in different sleep stages. A higher core body temperature has been associated with a decrease in restorative slow-wave sleep and subjective sleep quality. Similarly, a bigger difference in temperature between the core and the extremities which indicates that the body is not efficiently sending heat away from the core has been associated with; and a higher likelihood of waking up after falling asleep.

During REM sleep, the body; ceases most temperature-regulation behaviors such as sweating or shivering, leaving you more sensitive to ambient temperature changes. Accordingly, excessively hot ambient temperatures also appear to lessen the time spent in REM sleep.

How Cool Temperatures Affect Sleep

Sleep and wake cycles are governed in large part by our circadian rhythms. Around when we should be heading to bed, our body temperature takes a slight dip and stays lower until close to wake time. Body temperature also drops slightly in the early afternoon, coinciding with post-lunch sleepiness.

Science has yet to discover definitive causation between body temperature and sleep, but studies have shown connections. It appears that when temperatures are cool, this facilitates deep sleep. In contrast, warm temperatures may make sleep less restful.

In a Huffington Post article, professor Michael Decker, Ph.D., spokesman for the American Academy of Sleep Medicine, discusses temperature and rest. As we sleep, our body acclimates to the room temperature, he says. If we lower our body temperature a little bit in a cooler room, we tend to sleep better.

Dr. Christopher Winter went into more detail in another article, saying that the sleep cycle is typically initiated when our core body temperatures drop, and that people with higher internal temperatures may have trouble sleeping when the room is not cool enough to allow this to occur. Studies he mentions find that ideal temperatures are between 60-67 degrees, with cooler temperatures in this range being linked to deeper sleep.

A few studies have also looked at how temperature can affect sleep both in terms of biological impacts and on sleep quality.

    Sleep And Immune Function

    Scientists believe that sleep may help to regulate our circulating T and B cells . A strong immune system can fight disease more effectively. If good quality sleep facilitates better immunity, its no surprise that during times of illness we want to sleep more. But what has led scientists to draw a link between sleep, immunity, and disease recovery?

    A study published in Sleep Journal found that people who regularly slept less than 5 hours per night were much more likely to contract the common cold. The researchers concluded that a lack of sleep made people more susceptible to illness because it weakened their immune system.
