Why You Overheat in Bed
Your body temperature naturally drops to initiate sleep, but certain factors can trap heat. Common causes include heavy bedding, high room temperature, and memory foam mattresses that retain warmth. Hormonal changes, certain medications, and underlying conditions can also increase night sweats and overheating.
How Overheating Affects Sleep
When you overheat in bed, your body struggles to reach the ideal core temperature for deep sleep. This can lead to more awakenings, lighter sleep, and daytime fatigue. Chronic poor sleep is linked to higher stress and reduced productivity, which can indirectly affect work performance and daily decision-making.
Simple Ways to Stay Cooler
Use breathable, moisture-wicking sheets and choose a lighter blanket. Keep the bedroom around 65–68°F (18–20°C) and use a fan or open a window for airflow. If your mattress retains too much heat, consider a cooling mattress topper or a breathable hybrid design.
