According to research, leaving your house or going to bed with wet hair can trigger a cold and lead to a sore throat, runny nose, and irritating cough, especially in the cold, winter months.
In case you sleep in a warm room, then going to bed with wet hair won’t be as harmful. But, if the room you sleep in is at a cold temperature, then you should be cautious as your scalp will lose a large amount of heat energy.
There are three reasons why you should dry your hair before going to bed:
During REM sleep, your body temperature rises. Then your body heats and the moisture that creates in the towel your hair is wrapped in can cause severe headaches.
Pillows make an ideal place for bacteria proliferation because they absorb sweat, dead cells and natural oils from your skin. Wet hair will wet the pillow thus making a perfect ground for developing infections.
- Hair Breakage
When wet, hair breaks easily. Therefore, this is a bad habit for your appearance.
It would be best advisable to avoid going to bed with wet hair as this can result in mild to severe health issues. Also do not go to bed with dripping wet hair. At least wrap and drain the water with a towel first.
