Sleeping with the television on is a very bad idea as it can lead to an early death.
- 1 out of 3 French people watch television to try to get to sleep.
- Sleeping with the TV on is linked to early death, according to a study.
The finding is clear: according to a study by Northwestern University School of Medicine relayed by the Sun, wearing on the sleep of healthy adults aged 63 to 84, sleeping just one night with dim lighting, such as a TV without sound, increases blood sugar and heart rate.
Insulin resistance
Exposure to light at night would be “correlated with the higher prevalence of diabetes, obesity and hypertension” in older men and women, explain the authors.
In particular, they discovered that resistance to insulin, the hormone that regulates blood sugar, occurred in the morning in people who had slept in a lighted room.
Insulin resistance is when cells in your body (particularly muscle and fat) don’t respond well to insulin and can’t use the glucose in your blood to produce energy.
To compensate, your pancreas produces more insulin and your blood sugar levels rise over time.
Cardiovascular and metabolic disorders
What also surprised the researchers was the proportion of respondents (more than 53%) who said they slept with light in the bedroom.
“People should do their best to avoid or minimize the amount of light they are exposed to while they sleep,” said study author Phyllis Zee, chief of sleep medicine at Northwestern. University School of Medicine.
Indeed, people who slept with higher light levels were more likely to go to bed later and get up later, and “we know that night owls tend to have a higher risk of cardiovascular disorders as well. and metabolic,” explains Zee.
Besides television light, blue light, which alters melatonin, is also harmful to sleep. VSThis is why you should avoid charging your laptop or mobile phone in the bedroom.
