Is it safe to sleep with covers over your head?

Sleeping with covers over your head can pose some risks, primarily related to breathing and overheating. It may restrict airflow, leading to discomfort or increased carbon dioxide levels, especially if the covers are heavy or thick. However, many people find it comforting and safe as long as they can breathe easily and don't overheat. If you feel suffocated or excessively warm, it's best to sleep with your head uncovered.
