But what do you do if you want a cooler sleep environment, but your partner thinks it's too cold? Well, you can provide blankets and warmer clothes for your partner so you can turn down the AC. But there are other things you can do, too.
Use blackout curtains to keep your room from getting too hot and wear lighter, breathable fabrics while you sleep. Don't exercise close to bedtime, as this can raise your body temperature for several hours and keep you more alert. Take a shower or bath before bed. Look for sheets and pillowcases made of material that stays cooler longer.
You can even get a mattress topper filled with water that is cooled before you go to bed, sometimes to 60 degrees or lower. These are typically twin-sized, so you'll be the only one sleeping on a cooler mattress. Some even come with a feature that warms the mattress topper slightly in the morning, to help you wake up.
As you can see, sleep temperatures can have a surprising impact on the quality of your sleep. But even if your partner doesn't want the room as cool as you do, there are plenty of workarounds you can use to help cool down your body.
