Definition of circadian rhythms
Chronobiology is a branch of biology which studies circadian rhythms, that is to say the biological rhythms which fluctuate over a cycle of 24 hours.
The two types of circadian rhythms:
- Physiological rhythms: wake-sleep pattern, body temperature, etc.
- Biological rhythms: melatonin, cortisol, growth hormones.
These different rhythms are all synchronized together and are controlled by our biological clock, located in the superchiasmatic nucleus, themselves housed in the hypothalamus within our brain.
