Melatonin

What is melatonin?

To understand the origin of sleep, it's important to take a look at the pineal gland. Located in the brain, it reacts to the intensity of light by releasing more or less of a hormone called MELATONIN. This hormone acts to trigger sleep.

 

When the pineal gland works normally and steadily, the secretion of melatonin will be stronger at nightfall to trigger sleep, and will decrease at dawn for a smooth awakening.

Many causes exist :

 

  Stress

  Medications 

  Endocrine disorders

  Menopause / Age

  Jetlag

  Change of season

Circadian rythm and melatonin

ADHD and melatonin

Children with attention deficit hyperactivity disorder (ADHD) often suffer from poor sleep. Their rythm is naturally disturbed and the medications used to treat their ADHD can also worsen this disturbance. 

 

For some years now, physicians and paediatricians have increasingly turned to melatonin to help these children fall asleep faster and regain a restorative sleep.

 

Different studies show a sleep improvement in children taking melatonin.*
