Why does blue light ruin your sleep and how can you protect yourself from it?

In today's world, we are surrounded by screens – smartphones, laptops, televisions, and even LED lighting are our constant companions from morning until late at night. Unfortunately, exposure to artificial light, especially blue light , has a profound impact on our sleep, well-being, and health.

• What is blue light?

Blue light is a natural component of solar radiation that plays a positive role during the day – it stimulates the body, improves concentration, and boosts energy. The problem begins in the evening, when excess blue light disrupts our circadian rhythm .

• How does blue light affect sleep?

Evening exposure to blue light from screens causes:

• blocking the secretion of melatonin – the hormone responsible for falling asleep,

• shift in biological rhythm – difficulty falling asleep and shallower sleep,

• feeling tired in the morning – despite lying in bed for a long time, regeneration is worse.

Studies show that using a phone or laptop even an hour before bed can delay falling asleep by up to 1.5–2 hours.

• What to do to protect your sleep?

Fortunately, there are several proven methods to help minimize the impact of blue light:

1. Limit screens an hour before bed – turn on night mode on your phone, put your laptop away.

2. Choose warm light for evening lighting instead of cold LEDs.

3. Introduce relaxation rituals – reading a book, short meditation, calm music.

4. Use blue light blocking glasses – this is the easiest way to protect your eyesight and support natural sleep.
