Sleep - How much do you really need?
(Credit: Spongebob 1)
I am sure everyone have heard about the book "The Four-Hour Work Week" by Timothy Ferriss. I have not read the book, but I am sure there are a lot of information on self-improvement and time management. I am not sure how he did it, but with both online and offline work, I am effectively living on a "Four-Hour Sleep Day".
How much Sleep do we really need?
Well, the official school of thought is that every adult needs to sleep eight hours a night to be refreshed. I doubt more than 50% of the adult human race sleep 8 hours a night (lucky bastards). There are also those that thought having two split four hour sleep every 24 hours is the most effective sleep pattern.
Another extreme school of thought is the Polyphasic sleep pattern. It advocate a 20-40 min nap every 4 hour, so that you can get by with 4-6 hours of sleep a day. It is not recommended for normal lifestyle, but a good practice if you know you have to get by with less sleep on a busy schedule.
How much sleep do you have?
I find that I am able to get by with only a straight 4 hour sleep at night. But every 3-4 days, the sleep debt will hit a threshold and I automatically sleep a 8 hour sleep. So it averages to about 5 hour a night.
So I ask you : How much sleep do you get a night on average? Any 8 hour sleepers here?
