The balance of sleep obeys to a system of double pendulum.
- the Circadian Pendulum (de circa dia : around a day), modulates the pressure of sleep according to what time it is on the internal Clock.
- the Homeostatic Pendulum depends of the individual need for sleep on one hand and of the external constraints on the other hand.
