Cool Down or Heat Up: 3 Ways Temperature Affects Sleep

Man sleepingThe “best sleep ever” for a lot of people is lying on the softest mattress, with fluffy pillows and a cozy blanket. Rarely does temperature come into the picture when talking about it. But as sleep specialists in Ontario explain, an ideal temperature is the key to a restful slumber. How does cranking up or down your thermostat affect sleep? Here’s how:

1. Cool Temperatures Induce Drowsiness

Body temperature fluctuates throughout the day, but it takes a dive as bedtime nears. This slight dip in body temperature causes sleepiness. When you sleep in slightly cooler environments, you’re helping your body get that sometimes-elusive sleepiness.

The ideal temperature for sleep is between 65 and 72 degrees Fahrenheit. Set your thermostat around that range. If you have problems controlling the temperature in your bedroom, MacKay Heating & Cooling recommends calling heating and cooling experts to know what exactly is the problem with your unit.

2. Hot Temperatures Interrupt Sleep

You may be falling asleep faster in the cool, but if your AC has shut down in the middle of the night, the heat can interrupt your sleep. For one, it’s because the body would work doubly hard to cool off. You know well that “working hard” doesn’t exactly help when you’re trying to rest.

Experts also explain that hot temperatures reduce the time you spend on REM, the stage of sleep in which the body rejuvenates itself, repairing cells and strengthening the immune system. When you’ve spent so many times waking up drenched in sweat during the night, it’s not really difficult to know why you’re feeling tired and groggy, right?

3. Heat and Cold Can Come From Different Factors

While it’s important to pay attention to your thermostat, know that there are other elements that could influence temperature and sleep. Clothing, for instance. The thicker the sleepwear material is, the more difficult it will be for the body to cool off.

Wear thin, light clothes when sleeping. In fact, if you could strip down to your birthday suit, that would be better. Another element that could affect temperature and sleep is the mattress and beddings. There are certain types that could cause overheating. Be especially conscious of your choice.

Temperature plays a crucial role in your sleep. Find that sweet spot when setting the thermostat to ensure a restful slumber.
