Stars Insider's story
Many people fall asleep while watching television. When we fall asleep while watching TV in the living room, most of us think it's a signal to go to bed and head there, but what happens if we fall asleep while already lying in bed and watching TV? There is a very high likelihood that we will fall asleep with the TV still on.
However, sleeping with the TV on can affect the amount and quality of sleep, as well as overall health. However, there are also some potential benefits. Let's look at both sides in this gallery.

The sleep debt is determined by calculating the difference between the amount of sleep needed each night and the actual amount of sleep obtained.
Most adults need at least 7 hours of sleep. Therefore, watching a little more TV at night increases sleep debt. This is not good news for overall health.
Large sleep debt is associated with various health problems, including hypertension, heart disease, stroke, and diabetes. Additionally, sleep debt is related to an increased risk of car accidents and falls, especially among the elderly.
TV emits blue light. This type of light disrupts our biological rhythms (sleep-wake cycle).
Blue light inhibits the production of melatonin, which is a hormone that signals our body that it's time to sleep.
A systematic review in 2022 stated that exposure to blue light "can have negative effects such as reduced sleep quality and sleep duration."
Watching TV late at night can prolong the time it takes to fall asleep and reduce rapid eye movement (REM) sleep.
REM sleep has various restorative functions, including processing emotions and consolidating memories. It is the sleep stage during which we experience vivid dreams. Deprivation of REM sleep can affect how we regulate emotions and how memories function.
Watching TV right before falling asleep affects the time it takes us to actually fall asleep, but falling asleep with the TV on leads to deeper, more restful, and restorative sleep.
Watching TV stimulates the brain. Increased brain activity makes it harder to relax. Numerous studies have shown that using electronic devices before bed can negatively affect sleep duration and quality.
Turning on the TV and falling asleep causes the brain to continue receiving stimulation. The videos watched before falling asleep and the sounds heard during sleep both influence sleep quality.
A 2016 study published in Dreaming magazine found that what we see influences our dreams as well. For example, people who watch violent content are more likely to have dreams that include violence.

My parents always leave the TV on while they sleep.
This interferes with sleep.
Once again, I realize the importance of bed nets.
