How much sleep do we need?
This is a question of paramount importance to me. If I sleep too much, that’s a waste of time and productivity. But sleep too little and you will easily get sick. How much is this baffling ideal time?
According to NSF (National Science Sleep Foundation), it really depends on your age. And even within an age range, it can vary significantly. Here’s a hint if you’re seeking answers:

But basically, the optimal sleep time is an individually unique value. If you feel you need more sleep, then you probably need it. Read the multi-page article for more details.
I’m going with 7 hours per day. So at this fasting season, this translates to sleeping at 8 PM and waking at 3 AM. Another option seem to be sleeping like the usual months at 10 PM but getting an extra sleep at daytime.
(and here’s hoping that you don’t break the sleep schedule… again…)
PS: I heard that Indonesia’s first president Soekarno sleeps only 5 hours (IIRC) per day. If he can really endure that, I envy him very much…
