Needing a blanket to sleep, even during summer, is often linked to something called somatic self-soothing or deep pressure stimulation. It happens when the body naturally looks for physical comfort in order to feel calm, secure, and relaxed enough to fall asleep.
The gentle weight of a blanket can help the nervous system slow down by creating a sense of safety and stability, which may reduce stress, anxiety, and restlessness. That’s why many people sleep better when they feel covered, even if the room itself isn’t cold.
So if you can’t fall asleep without a blanket, it’s usually not just a random habit. It’s often your body’s way of self-soothing and creating the comfort it needs to fully settle down.
