Why we can’t sleep without covers, even when it’s hot

Blankets are an essential part of our bedtime routine

We are also “creatures of habit” and this has a huge impact on why we need our blankets. Even if it is not about feeling safe, we have been using blankets our whole life and it has been engraved in our routine since then. So, when we go to bed and cover ourselves with a blanket, our body receives a signal that it is time to sleep.
