In Ayurveda, nidra (sleep) along with ahar (food) and brahmacharya (right conduct) is said to be the three major physiological activities for maintaining homeostasis and health in human. It is said that a person sleeps when his mana (mind) gets exhausted and his functional indriyas (sense organs) detach themselves from their objects due to fatigue. The cause of sleep (nidra) is tamo guna and the cause of waking is satwa guna. Nidra comes by swabhawa (nature) no other cause is needed. In tamoguna predominant person, sleep comes during the day as well as at night. In the rajaguna predominant person, there is no specific time for sleep, sometimes it comes in the day at night due to the unstable nature of rajaguna. In satwa guna person sleep comes at midnight. In persons with decreased kapha and increased vata and who suffer from mental and physical pain sleep doesn’t occur at all. It’s called vaikariki nidra.
(Satwa, Rajas, and Tamas are called Trigunas of mind – three types of mindsets. Satwa is the pure state of the human mind. Rajas and Tamas are disorders according to Ayurveda. The type of mindset a person acquires defines his personality as well as health. Vata, Pitta, and Kapha are called Tridosas in Ayurveda. These entities when get vitiated cause different diseases and discomforts. Their balanced state determines the health of the person.)

Enjoying excess sleep leads to diabetes.
