Everyone at least once in their life fell asleep with the TV on. In the article we will tell you whether such a habit is harmful and what the alternatives to fall asleep quickly are.
How TV affects the quality of sleep
Decreased production of melatonin
Turning on the TV during sleep reduces the production of the sleep hormone melatonin. This leads to disruption of human circadian rhythms.
The fact is that the TV screen, like any gadget, produces blue light.
The wavelength of blue light is equal to that of the sun, which is why the human body thinks it's time to wake up.
For quality sleep and fast falling asleep, give up any gadgets 2-3 hours before bedtime. This includes phones, laptops, tablets, and TVs.
Stimulation of the brain
As long as the TV is on during sleep, the brain is not able to fully switch off and relax.
The brain continues to process content from the TV.
Therefore, it is important to choose programs that do not cause fear or anxiety.
In general, this type of sleep, along with the TV on, disrupts rest and reduces the quality of sleep.
REM sleep cycle disorder
Turning on the TV disrupts sleep cycles and turns on REM sleep.
Frightening content can lead to nightmares that people usually have during REM sleep.
In addition, disruption of sleep phases leads to memory impairment and a decrease in cognitive functions in humans.
If you need sound before bed, use a white noise audio recording or a recording of birds singing before bed.
