On top, if one is constrained to sleep less during the week (6-5 hours per night) how can he/she increase the stamina/energy levels without having to sleep 12 hours during the weekend ?
Not really possible to 'catch up'. Matthew Walker's book 'Why We Sleep' goes in depth on this. It really made me re-think my life and ensure I'm getting enough sleep daily.<p>I can't do it justice, but sleeping 8 hours > sleeping 6 and napping 2 later.<p>So sleeping 5 hours 5 days a week and 12 hours on the weekends just doesn't cut it.
There is considerable debate over the question of “sleep debt”, with current thinking tending towards the idea that it doesn’t exist.<p>As to sleeping less during the week, the three major ideas are polyphasic sleep (doesn’t work), cocaine (works, may kill you), and “rethinking your priorities”.
People say you can't catch up, but your body definitely thinks it's doing something useful when it gets that extra sleep.<p>The simple matter is, if you're sleeping extra on the weekend, you aren't saving any time by sleeping less during the week.
I used to be a serious workaholic, sleeping 3-5 hours a night during the week-days and, as you suggest, catching up in the weekends. I also used to be a moron. In retrospect, both states were correlated.<p>The first wake-up call was when I moved from Belgium to the US. In Belgium, one enjoys much more paid vacation than in the US. This discrepancy showed me that I did not truly recover in the weekends - I needed my vacation days to recover.<p>Though I consider the work-life balance a misnomer (you have one life; part of the time you 'work,' part of the time you do other things), it is still something you need to regulate. First of all, assuming you are what I would like to call a 'knowledge' worker, you need to do other stuff to keep your mind fresh.<p>Secondly, as a rule of thumb, I would suggest that if your job requires you to work 10+ hours a day, you are doing your job wrong. Though it might sound odd, this is a useful rule of thumb. Whenever you find yourself in such a situation - STOP. STOP and reconsider.<p>EDIT: changed to 10+ hours... (btw: this includes transit)
I did this for years and learned both from experience and later from reading the works of people who know much more about sleep than I do (highly recommend the book "Why We Sleep" that this kind of catchup is not possible. I found myself being exhausted and sleeping most of the day on weekends and over time this just kept getting worse and worse. I felt fine during the work week getting 3-6 hours of sleep, but on weekends I'd just crash. No, I was not catching up on my sleep debt by passing up for 12-14 hours on weekends instead. Now I make sure to give myself at least an eight-hour sleep opportunity per day. As a result I feel more alert more consistently, and my weekend sleep/wake schedule looks very similar to my normal weekday schedule.
Its important to have a consistent sleep pattern; trying to regain sleep on the weekend will just throw your sleep cycle out of whack. Personally, I get about 5 hours on average during work, and I am often far more tired after a super-sleep on the weekend.<p>Other things that help are not eating just before bed, and ensuring you have enough time in the morning to actually wake up! Oh, and get the best mattress you can afford
Cocaine?<p>More seriously, sleep is physiologically essential - but so are other things. So make sure you optimize the hell out of the other things, starting with diet & exercise. (I'm guessing that "optimal" exercise under sleep deprivation is less than with adequate sleep but more than zero.)<p>Try to take naps. If you have enough downtime take a chance to nap rather than e.g. surf the web or futz with your phone.<p>Spend time on weekends preparing so you can sleep more during the week. E.g prepare food and have it as close to ready to eat as possible. Minimize the errands or cleaning you have to do on weekdays by doing it on weekends and spend the time saved on weekdays (if any) sleeping.<p>Also try to figure out how to get out of this unhealthy situation.
