The amount of sleep people need varies from person to person as far as I know. I prefer to sleep 7 hours in the night and take a nap in the afternoon, and that leaves me feeling pretty good most of the day. Some people I know can sleep less than that and feel fine, others sleep more than I do and need it.
As far as I know, sleep is an extremely complex topic that we still don't understand all that well, and in my opinion this seems overly simplistic. I do like the presentation though!
Thanks for the thoughtful words. I agree this is an overly simplistic view not taking into account age, lifestyle, or anything. Sleep is indeed a very complex topic, the intention with this was just to try to cleanly and simply visualize how sleep debt could play out :)
This would be much more interesting if it asked you about symptoms of sleep deficit. E.g., "if you go into a dark room and lie down in the middle of the day, how long will it take you to fall asleep?"
Someone who habitually sleeps 6 hours a night but never feels tired is probably fine. Someone who habitually sleeps 8 hours a night but always feels tired should try sleeping more, and if that doesn't work they should seek advice from a doctor.
I expect there is a large segment of people who suffer from sleep deficit and would be more effective if they slept more, but don't know that it would help them. I don't think this is the correct way to reach such people, or the correct message to give them.
Science seems to contradict the premise of this project. The research out there seems to suggest anywhere from 5-7 hours can be a healthy amount for an adult human.
This sort of project could cause anxiety about lack of sleep therefore causing a further lack thereof.
TLDR: If you're tired sleep. If you're not.. stay awake.*
* A well balanced diet and exercise regime are recommended in order for this point to be valid.
Nice to see how it all adds up over time, at least it isn't compounding like my mortgage interest.
Couple UI notes, when I put in 7.2 the UI doesn't round the resulting 5.5999999999 to something reasonable so overflows text. Also it might be nice to have a gradient of colors (or at least a yellow alert) it is a little abrupt that 7.99 hours is "Drowsiness is red alert" and 8.0 hours is "perfect amount of sleep".
Similarly, I was issued a stern warning for sleeping 7.999 hours each night. The danger of losing "0 hours" of sleep over the course of a year was quite alarming to discover.
With a little less teasing: ignoring issues with assuming that humans are physiologically identical, the assessment could stand to be more sensitive to the significance of deviations from the proposed norm.
