Some people sleep hot regardless of mattress, bedding, or room temperature. This can be frustrating, especially when standard cooling advice doesn’t seem to help.
In many cases, sleeping hot is influenced by internal factors, not just the sleep environment.
Metabolism and Body Heat
People with higher metabolic rates tend to generate more body heat, even at rest. This can lead to overheating during sleep, especially when airflow is limited.
Hormones and Temperature Regulation
Hormonal changes can significantly affect sleep temperature. Fluctuations related to stress, aging, or natural cycles can interfere with the body’s ability to regulate heat efficiently.
Stress and Sleep Heat
Stress activates the nervous system, which can raise core body temperature. Even subtle stress can lead to restlessness, sweating, and disrupted sleep.
When Environment Isn’t the Problem
If cooling the room helps inconsistently, the issue may not be temperature alone. Layered solutions that address airflow, moisture, and body regulation often work better.
Understanding why your body runs hot is essential for choosing effective solutions.
