In short:
Lack of sleep weakens our immune defenses. And conversely, getting sick harms our quality of sleep. A truly vicious cycle, one that can be broken with the right routine and the right lighting.
đź“Ś Summary
Sleep: the pillar of immunity
Getting enough sleep isn't a luxury: it's a biological necessity. During deep sleep, our body strengthens its immune defenses. It produces more cytokines, molecules that fight infection and inflammation.
Chronic sleep deprivation makes you more vulnerable to viruses and bacteria. Even a single sleepless night reduces the activity of natural killer cells. Fatigue weakens the body's first line of defense.
When illness disrupts our nights
But the opposite is also true: when you're sick, sleeping becomes more difficult. Pain, fever, cough, or anxiety often prevent you from reaching the deepest, most restorative stages of sleep.
This lack of recovery slows healing. We then enter a cycle: the illness prevents us from sleeping, and the lack of sleep worsens the symptoms. A vicious cycle that must be broken as soon as possible.
Why sleep-wake rhythm matters
Our biological clock controls melatonin production and immune system regulation. If it's disrupted—by stress, screens, or artificial light—our entire body suffers the consequences.
Maintaining a stable circadian rhythm helps strengthen immunity. This includes regular bedtimes, natural light in the morning, and most importantly, a lighting environment consistent with the time of day.

How to break out of the vicious circle?
To support sleep and immunity, you need to recreate natural nighttime conditions. Here's how:
- Avoid blue light in the evening (screens, cool white LEDs).
- Expose yourself to natural light first thing in the morning.
- Adopt a regular rhythm of going to bed and getting up.
- Use soft, warm light in the evening to signal to your body that it's time to sleep.
Laqi bulbs automatically adjust their temperature and intensity to your biological rhythm. No more juggling settings and schedules: Laqi takes care of it for you.
đź’¬ FAQ
Why do we sleep more when we are sick?
The body requires rest to mobilize its immune defenses. It's a physiological survival reflex.
Can we heal faster by sleeping better?
Yes, good sleep supports cell regeneration and strengthens antibody production.
Does stress prevent healing?
Stress disrupts sleep, weakens immunity, and slows recovery. A cycle that needs to be broken.
Sleeping better is already the beginning of healing.
Sleep and health are deeply linked. By acting on one, we positively influence the other. Prevention is better than suffering: equip yourself to sleep better.
