Is there any mention of the minimum or maximum number of sleeping hours for humans in Vedas, Puranas, Ayurveda, or any other scriptures?

  • You can see breakdown of what brahmins are expected to do in a day of 24 hours - hinduism.stackexchange.com/questions/21054/… - approximately sleep is between 8.30pm & 4.30am, cos there is some leeway in when to go to sleep.

You should wake up before sunrise, and go to sleep after sunset. Here is what this chapter of the Manu Smriti says:

If the sun should rise or set while he is sleeping, be it (that he offended) intentionally or unintentionally, he shall fast during the (next) day, muttering (the Savitri). For he who lies (sleeping), while the sun sets or rises, and does not perform (that) penance, is tainted by great guilt.

And here is what this chapter of the Gauatama Dharma Sutras says:

Let him who was asleep when the sun rose remain standing during the day, continent and fasting, and him who was asleep when the sun set (remain in the same position) during the night, reciting the Gâyatrî.

    These verses are just saying one should not be sleeping during these two Sandhyas. That one should wake up during Brahmamuhurta is well known, but from these verses we can't calculate the recommended hours of sleep because there is no clear instruction given as to when exactly to retire to bed at nite.

  • @Rickross I disagree. If you are to be awake at sunset, the clear implication is that the sleeping hours of the night should be after then. Jan 14 '18 at 8:55
  • One should never sleep just after sunset. The time of Sandhyas are very auspicious because that is the time Lord Shiva roams on Vrishabha with Parvati. This is also the reason why Diti got Daityas as sons as she sported with Kashyapa at evening time.

  • @TheDestroyer Well, anyway at least Dvijas perform Sandhyavandhanam before, during, and after sunset, also at least for them there's no question of going to sleep immediately after sunset. Jan 14 '18 at 12:10
  • The question is minimum and maximum hours. I can be awake at three sandhyas but how does that show number of hours spent in sleep ? Jan 14 '18 at 15:11
