Covering Face While Sleeping: Oxygen Deprivation & Health Risks

• * Sleeping with a blanket over the head in winter can be harmful despite providing warmth and a sense of security.
• * It reduces fresh oxygen intake and increases carbon dioxide, potentially leading to headaches, fatigue, and long-term brain impact.
• * Breathing stale air can disrupt deep sleep and worsen conditions for asthma and allergy sufferers due to dust and allergens in blankets.
• * The warm, moist environment created under the blanket can negatively affect skin, potentially causing pimples or itching.
• * While it offers warmth and blocks light, experts advise against it for overall lung and brain health.

Why It Matters: A common winter sleeping habit can negatively impact your health and sleep quality.
