Why do most living beings sleep at night

Living being’s brains contain pineal glands, which secrete the hormone melatonin. The level of these hormones rises at night and is responsible for sleep. In daylight, the level of this hormone decreases, resulting in animals waking up from sleep. This is a cycle which operates throughout life and is known as ‘circadian rhythm’. There are many such rhythms operating in biological systems.
