What are the main functions of the pineal gland?
The main hormone produced by the pineal gland is melatonin, often referred to as the ‘sleep hormone’, which regulates the body’s circadian rhythm (internal or biological clock).
Melatonin is a hormone found in humans, animals, fungi, plants and bacteria. It participates in different cellular, neuroendocrine and neurophysiological processes, such as controlling the daily sleep cycle of the body. Deficits of this substance can result in insomnia and depression.
The pineal gland works by responding to the variations of light that occur around us, releasing different amounts of melatonin depending on how light or dark it is. For example, when it is dark, the pineal gland releases greater amounts of melatonin, making us feel sleepy.
The pineal gland is also linked to a range of other key body functions:
- Strengthens the immune system
- Promotes healthy bones
- Regulates endocrine functions
- Regulates the circadian rhythm and sleep cycles
- Regulates seasonal rhythms, stress, physical performance and mood
- Influences sex hormones
- Plays a role in spatial navigation
