Temperature plays an important role in sleep quality.
The body naturally lowers its temperature slightly to enter deep sleep. When the room is too warm, this cooling process becomes more difficult, and the nervous system stays more active.
This can result in:
-
Less restful sleep
-
Increased heart workload
-
Nighttime discomfort
Many sleep experts recommend maintaining a bedroom temperature between 15°C and 19°C (59°F–66°F) for optimal rest.
If the room feels cool, adding an extra blanket is usually better than increasing the heating too much.
2. Sleeping in a Position That Restricts Breathing
Sleep position can significantly influence breathing patterns.
For some people, lying flat on the back may contribute to interrupted breathing during sleep. This condition, often linked to snoring, can cause repeated drops in oxygen levels.
When breathing becomes irregular, the body responds by increasing heart activity, which can happen many times throughout the night.
Simple adjustments may help, such as:
-
Sleeping on your side
-
Using a slightly elevated pillow
-
Ensuring the head and neck are properly supported
These changes can improve airflow and promote more comfortable sleep.
