Can get a good night sleep because you feel like you are freezing no matter what While the body needs to be relatively cool to fall asleep comfortably, an excessively cold room can jeopardize rest, making it hard to achieve the rejuvenating sleep required for thriving during the day. However, the ability of cold to disturb your sleep doesn’t mean you can’t take specific measures to address potential issues. Here are the main ways in which cold affects our sleep and how to counter these problems. It’s Harder to Fall Asleep A too-low temperature can make it challenging to fall asleep because the body tends to constrict blood vessels to conserve heat, making it more difficult to reach the ideal body temperature for sleep. If you are too cold during sleep, the body can alter its cardiac autonomic response, meaning the heart rate will increase, heightening anxiety and preventing the necessary relaxation for easy sleep, Drafts Can Cause Shallow Sleep If your home is full of drafts, the quality of your sleep may be significantly affected. Cold drafts can disturb sleep, causing frequent awakenings during the night. This happens because drafts can lower skin temperature, causing the body to wake up at night to maintain an optimal temperature. When it’s Cold, the Body Has to Work Harder Pumping blood vigorously to stay warm throughout the night can strain your body and negatively affect sleep. While various studies have noted that cold has a better effect on overall sleep quality than heat, excessively low temperatures are problematic because they force the body to work harder to maintain a constant internal temperature.
