Most people sleep once every day or every 24 hour period, for an average around 7 or 8 hours.
We only have a time period equal to a 24 hour day-night cycle because of living on this specific planet in this specific solar system. The absolute length of a cycle of day-night on any other planet would be different.
There are people sleeping multiple times per cycle. The most common case is those having a short sleep in the early afternoon as a cultural or personal habit.
One extreme example was a man doing a solo world navigation, he got used to micro-sleeps, such as a few minutes, whenever he could and many times per 24 hours cycle, because he didn't have any partner to watch the ship and the sea conditions. So he had to be awake as often as possible to be able to react.
Apparently there are also people sleeping every two days or on similar non daily patterns. I did an internet search on that one. Some people wrote they sleep like 10 or 12 hours every two days. Some even say every 3 days on places such as reddit.
My question is thus, baring any professional, social and relationship obligations, or any illness conditions, or adaptation times, are there any biological reasons that atypical sleep patterns would be personally harmful compared to "typical" sleep patterns for humans (typical being of one long sleep at night every day-night cycle) ?
Another question I have, loosely related, is about the viability of deep meditation as partial replacement for sleep.
