For sure a lot of us have the habit of sleeping with our blankets or anything on our bed covering our head. But now it may be wise to try and avoid this habit, that is if you want to avoid diseases like Alzheimer’s disease. A study can attest to that.
The study found that sleeping with the head partially or fully covered by bedding would result in a 92.8% chance of suffering from either an early stage, middle stage, or late stage of dementia, by the age of 70.
The study considered that sleeping in a restricted air space would result in a depletion of oxygen over time accompanied by an increase in carbon dioxide through re-breathing, the repeated inhalation of exhaled air. This can result in episodes of hypoxia.
