Stress Day doesn’t end just because the light is off. After a busy day, your body stays in defense mode: tension, restlessness, alertness. Noradrenaline stimulates the wakefulness center; falling asleep becomes difficult. The natural transition to rest slows down, sometimes by several hours. Every annoyance replays the scene in your head, restarting the “stress → wakefulness” cycle. As long as the alert remains, your night stays fragmented and unrecovering. Yes, it's me! Learn more

Thoughts racing in your head Your brain plays a movie when you want to press “pause.” As soon as you cling to a thought, excitement or fear sends the brain the signal to stay awake. Like watching a gripping story, it becomes difficult to fall asleep. Even without realizing it, your attention remains too high. Noises and micro-stimuli further amplify mental presence. The more you listen to this flow, the further sleep drifts away. Yes, it's me! Learn more

Worries When life goes off track, sleep follows. Breakup, job uncertainty, low mood: worries keep the brain alert. They trigger a physiological wakefulness response and block falling asleep. The bed becomes the place where you ruminate, and the night, a stage where problems replay. Without correction, the brain gradually associates bedtime = anxious wakefulness. The risk: insomnia that settles beyond the difficult episode. Yes, it's me! Learn more

Night awakenings Awake at 3 a.m., eyes wide open, for no apparent reason? Sleep progresses in cycles; at their end, vigilance rises and the slightest noise can pull you out of bed. The real trap is the difficulty to fall back asleep quickly. Checking the clock, calculating "I only have... left", and the fear of not succeeding feed the anxiety. This worry activates the alert state (hyperactivation of the autonomic nervous system). Result: racing thoughts, body alert, and a night that stretches unnecessarily. Yes, it's me! Learn more

Chronic insomnia By dreading the night, it's the night that dreads you. A few bad nights are enough for the fear of "not sleeping" to arise. This performance anxiety self-sustains wakefulness: the more you want to sleep, the less you manage. Stress activates the alert state, vigilance rises, and the cycle closes. You end up giving in from fatigue, too late, exhausted in the morning. The heart of the problem: break this conditioning and defuse the fear. Yes, it's me! Learn more

Noisy environment It's not always the noise that wakes you up, it's your reaction to the noise. The same sound puts some to sleep and wakes others: it's all a matter of reactivity. Sound variations (snoring, neighbors, traffic) trigger the internal alarm. Getting annoyed by noise reinforces wakefulness and keeps the brain on alert. The more you listen, the more the noise takes up space — and the less sleep finds its place. The challenge: reduce sensitivity and shift attention so the sound becomes neutral again. Yes, it's me!

Pregnant woman When you're expecting a baby, you don't always expect sleep. Reflux, cramps, discomfort, frequent urges: the body often wakes up. Added to this is anxiety (health, childbirth, organization), which keeps the alertness going. The combination of pain + vigilance makes falling asleep fragile and the nights fragmented. The brain focuses on the discomfort and the passing time, which increases the perception of discomfort. Reducing reactivity and calming the mind becomes essential. Yes, it's me! Learn more
