Hi All, I have noticed one thing that many people cover their head while sleeping and today i did it because its cold out here so cant use fan and our mosquito repellant was not working, So had to cover myself but due to that i was unable to sleep properlly. Experts say covering the head incerase the concentration of carbon dioxide and decrease concentration of oxygen that may lead to brain damaging effects. Other reason which lead to brain damaging are: Smoking, air pollution, High sugar cunsumption. Yes Its true today when i woke i was not fresh. Do you cover your head while sleeping? are you able to get proper sleep if you cover the head? share with us!!
