Do we fall asleep faster or slower with the TV on? Is blue light to blame for insomnia? How does the TV affect our body during sleep?

The feeling of security provided by a familiar voice in the background means an evening without anxiety for many. A television that runs while we sleep is not only a harmless companion, but a silent troublemaker the body's natural rhythm.

While a series, movie, or show seems to be they are rocked to sleep, the truth is often different. The body and mind are not resting as they should, and light and sound stimuli trigger unexpected consequences behind the scenes.

When light disrupts the internal clock

TVs emit blue light that affects performance melatonin hormone – the one that tells the body that it's time to sleep. Even though your eyes may be closing, your brain is receiving conflicting signals: wakefulness instead of rest.

The consequence? Later falling asleep, frequent awakenings, and shallower sleep. REM sleep – a key part of sleep for memory recovery and brain detoxification – is shortened or even eliminated.

Constant stimuli – silent stress

Although we think that television relaxes us, in reality the brain They function more actively, constantly processing sounds and light changes. The body remains on alert, the heart rate does not completely calm down, and the muscles remain tense.

This results in poorer quality sleep, and waking up often feels tired, irritable, and lacks concentration. Over time, this leads to mood problems and even an increased risk of chronic diseases.

When the body does not enter deep rest phases during sleep, metabolism slows down, hormonal balance is disrupted, and defense mechanisms weaken. In the long run, this means greater susceptibility to disease and lower resistance to stress.
