In a world where everything—from work to leisure—happens on a screen, it's no surprise that their phone is the last thing many people look at before falling asleep. However, this seemingly harmless habit could be profoundly affecting your health. A new study has revealed that prolonged screen use in bed increases the risk of chronic insomnia by 59% .

Why do screens affect sleep so much?

1. Blue light and circadian rhythms
Electronic devices emit blue light, which tricks the brain into thinking it's still daytime. This light suppresses the production of melatonin, the hormone that regulates sleep. The result: you have more trouble falling asleep and your rest becomes superficial.

2. Cognitive overstimulation
Watching the news, replying to messages, or watching TV series activates brain regions related to alertness, attention, and emotion. This disrupts the natural relaxation process that precedes sleep.

3. Night anxiety and digital dependence
Furthermore, using your phone in bed reinforces a cycle of anxiety: you need to check notifications, but that fuels stress, making it even harder to rest.

How can you protect your rest?

• Digital disconnection : Turn off all devices at least 1 hour before going to sleep.

• Sleep hygiene : Create a nighttime routine: warm bath, reading, meditation or aromatherapy.

• Screen-free bedroom : Transform your bed into a sanctuary of rest, without cell phones, tablets or laptops.

• Night mode : If you can't avoid it, use blue light filters or "night mode" on your devices.

Sleeping well is not a luxury: it is a fundamental pillar for your emotional, hormonal, immune and mental well-being.
