One evolutionary hypothesis suggests that these jolts are a vestige of our ancestors sleeping in trees . The brain would then test our reflexes to avoid a potential fall .

Factors that accentuate these spasms
Certain elements can promote these nocturnal jolts :
- Stress and Anxiety : An overactive brain continues to send signals to the body, even when resting .
- Caffeine and stimulants : They delay falling asleep and increase muscle nervousness .
- Late physical exercise : It keeps the muscles awake and complicates the relaxation phase .
- Lack of sleep : A sleep debt makes falling asleep more abrupt and agitated .
Should we be worried?
Good news! These tremors are benign and affect 60 to 70% of people, regardless of age or gender . They are therefore not considered a sleep disorder.
When to see a doctor?
- If these spasms are frequent and prevent you from sleeping.
- If other symptoms (cramps, pain, chronic fatigue) are present.
- If you experience a feeling of paralysis or repeated hallucinations.
How to reduce these nighttime jolts?
- Adopt a calming routine : relaxation, meditation, reading…
- Avoid caffeine and screens before bed.
- Opt for a regular and sufficient sleep rhythm.
- Exercise during the day, but avoid intense sessions in the evening.
