Imagine this. Your air conditioner is broken (or maybe you don’t have one). You’re in your bed, wearing a tank top and undies, laying only under a thin sheet. You feel the fan blowing on you, but all that you can feel is hot air blowing across your body. Now envision this. You’re in your bed, snug as a bug in a rug, comfortably tucked under a sheet, a blanket, and a comforter. Just like Goldilocks, you don’t feel too hot or too cold. You do feel the cold air from the fan blow briskly across your face. Your eyes are closed and you float easily to sleep. Why is it that you sleep so much better when it is cooler?
There are a few reasons to explain why sleeping cold versus sleeping hot can be considered better:
- More comfort - Have you ever been so hot that you just didn’t know what to do? Alternatively, if you are cold you can always “cover-up”. Sleeping cooler just feels better than sleeping warmer to most people.
- More metabolism - Your metabolism can work better in cooler versus warmer temperatures.
- More melatonin - Though this is a supplement that can be purchased over-the-counter in the US, melatonin is a hormone that is naturally produced by our bodies. Cooler temperatures are helpful in the release of this hormone, which can lead to better sleep.
- Less insomnia - Rooms with cooler temperatures are believed to help people experience less insomnia than rooms with hotter temperatures.
- Less disease - It is also believed that sleeping cooler can benefit your health by decreasing your chance of diseases.
What are some ways to sleep cooler?
- Use water - Drinking water and staying hydrated can help regulate your body temperature, which in turn can make you feel cooler while you sleep.
- Use a ceiling fan - Fans can help circulate the cool air around the room which can help you feel cooler.
- Use cooler sheets - Some sheets stay cooler than others, depending on what they are made of. Look for sheets which have stay-cool technology.
- Use a cooler pillow - As with sheets, the materials used to make pillows can make you feel hot or keep you cool.
If you have breathing issues, such as those brought on by asthma, you may want to discuss with your medical professional what an optimal temperature might be for you. If not, get ready to turn down the thermostat and then go snuggle up because it’s time to get cool.
