A person might also try the following strategies, from the American Sleep Apnea Association:
- Keep the windows closed at night if the inside of the house is cooler than the outside.
- Use cotton sheets.
- Take a cooling shower or bath before bed.
- Avoid alcohol close to bedtime.
- Try using a frozen, gel-filled eye mask.
- For a short-term fix, freeze the bedding in a plastic bag during the day.
- Fill a rubber hot water bottle with cool water, keep it in the freezer, then place it in the bed before going to sleep.
- Place a pan full of ice in front of a fan to cool the air.
When a person sleeps, the brain cycles through rapid eye movement (REM) and non-REM stages.
Non-REM sleep comes first, and it involves:
- a brief transition period into sleep
- light sleep, when body temperature drops and breathing, heart rate, and brain waves slow
- deep sleep, which a person needs to feel refreshed
Next comes REM sleep, when the eyes move rapidly, though they are shut, and brain waves resemble those of someone who is awake. Breathing increases and the body is temporarily paralyzed.
During an average night’s sleep, the body cycles through these stages a few times, gradually spending more time in REM sleep and less time in non-REM sleep.
