was wondering how long does it take to get adjusted to 4,5h of sleep. I feel great after my 1,5h hours nap, but I'm quite tired during the day. Does it take longer to get used to 4,5h of sleep than to 6h of sleep?
Another thing is that I've overslept a couple of times from 3.00 to 7.30. I've first woke up at 6.00 but somehow turned off the alarm and woken up automatically at 7.30. It felt pretty good, but I'd much rather sleep 4,5h. It's great to do all my work from 12.00 to 3.00 when everyone is asleep and wake up
at 6 to read all the newspapers before they wake up.
So should I switch my schedule to 6h instead of 4,5h or just wait to get adjusted?
No doubt it varies from person to person, but in my case I didn't get used to the 4.5 hours in a week or so and switched to 6 hours per day. That feels right to me, and there's never any feeling of having a sleep deficit.
As to the question of switching from 4.5 to 6, I'd say you may as well. 6 hours' quality sleep is a lot better than 4.5 that leaves you tired. There won't be any transition time involved, the 6 will just feel like you've slept in. Try it and see.
