Sleeping badly could be the result of too much television
Watching TV in the evenings could cause people to get too little sleep, researchers have found.
Psychiatric researchers from the University of Pennsylvania found that TV viewing is the most important factor in determining how much sleep a person gets.
A study of more than 21,000 adults found that TV has become the cue for sleep, taking over from hours past sunset, or how tired we feel.
Staying up to watch the end of a programme can result in people getting too little sleep, which has a knock-on health effect, reports the Mail. Sleep deprivation has been linked to obesity, depression, diabetes and heart disease.
