Research data found people who go to bed from 10 p.m. to 11 p.m. and fall asleep before 11 have a much lower risk of developing cardiovascular disease than those who go to bed earlier or later.
Lack of sleep is associated with cardiac morbidity and mortality and fragmented sleep is linked to atherosclerosis and inflammation.
Sleep deprivation is linked to a significant number of other health problems including obesity, mental health conditions, dementia, impaired immune function, increased risk of cancer and increased risk of pain-related conditions.
