Tossing and turning at night often ends once we pull on a blanket—almost like magic. Even on hot nights, many of us can’t sleep without one.

There are a few reasons for this. First, blankets help regulate body temperature. During deep sleep,

our body loses some ability to control heat, and a blanket helps maintain comfort.

Blankets are also part of our routine—we’ve used them our entire lives, and our bodies associate them with sleep.

They signal it’s time to rest, helping us unwind. Covering up can also reduce stress and anxiety by boosting

serotonin, a chemical that helps us feel calm and relaxed.

Additionally, blankets create a microclimate, shielding us from changes in temperature and allowing us to fall

asleep faster. Finally, they offer a sense of safety—something many of us learned as kids hiding under the covers from the dark.

So yes, even on warm nights, blankets help us sleep better by providing warmth, comfort, and emotional reassurance.
