For the last fifty-five years
I have not lain down to sleep.
Twenty-five years have passed
since I eradicated drowsiness.”Pañcapaññāsavassāni,
yato nesajjiko ahaṁ;
Pañcavīsativassāni,
yato middhaṁ samūhataṁ.
Anuruddhattheragāthā
The Buddha slept for 90 minutes. If you learn about sleep cycles, that makes sense because a sleep cycle is 90 minutes long.
The human body cycles through 2 phases of sleep, (1) rapid eye movement (REM) and (2) nonrapid eye movement (NREM) sleep, which is further divided into 3 stages—N1 to N3. Each phase and stage of sleep includes variations in muscle tone, brain wave patterns, and eye movements. The body cycles through all stages approximately 4 to 6 times each night, averaging 90 minutes for each cycle
