How to Sleep Less and Stay Healthy

How much sleep do we really need? Of course it’s very personal, but “seven to eight hours should be enough” is what we keep hearing from most sources. But is it possible to shorten this time, without hurting your health?

Indeed, sufficient sleep time is important for your body to function well during the day. Sleep helps your body to recover from illness, minimizes the effect of stress, increases ability to concentrate, and improves memory and coordination. You don’t want to put these abilities at risk, do you?

The good news is that it is possible to shorten sleep time by up to 1 hour without the risk of sleep deprivation if you understand and follow these two simple rules.

How to Sleep Less

Rule 1. It’s not just the quantity of sleep that counts, but also the quality.

Everyone has woken up after 10 hours sleep and felt fatigue, as well as getting up after 6 hours of sleep feeling completely refreshed and rested. There are many factors that may influence how long you need to sleep to feel rested, but the rule is simple. The higher is the quality of your sleep, the smaller amount of sleep time you need. This is the first recipe in shortening your sleep time. It seems to be logical, but how you can improve the quality of your sleep? There are a number of ways to do it but the most practical are:

  • Do not eat before going to bed (at least 2 hours before sleep time).
  • Sleep in dark, quiet room.
  • Try using a sleep optimization program. These work wonders for some people.
  • Sleep with fresh air (open windows or get air refresher).
  • Exercise during the day. If you don’t exercise, go for a 15 minutes walk before the sleep time.
  • Do not watch TV in the bed before going to sleep. Read a book, take a bath, do something relaxing.
  • Don’t drink coffee or other stimulants within 6 hours of bed time.
  • Don’t take long naps (more than 30 mins) during the day.

Follow these simple tips and within one or two weeks you will notice how your sleep starts improving.

Rule 2. Any habit can be changed, slowly

There is an old African proverb. “How do you eat an elephant? One bite at a time.” The same is true for changing your sleep habits. When do you go to sleep, how long you sleep, where you sleep –- it’s all part of the sleeping pattern that your body is accustomed to. Like any habit, it can be changed by taking small but regular steps.

Start waking up 5 minutes earlier every 2-3 days. In one week, you’ll be waking up 15 minutes earlier. In one month, you’ll be waking up 1 hour earlier! To make it even easier, you can take slower steps and extend your experiment for 2 or 3 months by shifting your sleep time by 5 minutes a week. To succeed in this experiment, you should try and go to bed at about the same time every day. It requires discipline, but result is well worth it.

As you start sleeping less and less, it’s crucial to remember and follow the first rule about quality sleep. This is your only way to compensate for less sleep.

Just imagine what you can do with all the free time you can get from waking up earlier. If you can manage to get one extra hour per day you’ll end up with 365 hours per year –- that’s equal to 9 work-weeks of productive time! By utilizing this time you could learn a new language, read dozens of books (or even write some!) and start exercising regularly. Morning time is also the most productive time. No wonder the early rising habit is so common among successful people. Become one of them!

    Sure, you can condense your # of sleep hours IF you can successfully improve the quality of your sleep, but to be alert, happy and productive during the day, the vast majority of people in this nation need to sleep more, not less. I fully recommend “The Promise of Sleep” by the big name in sleep research, Dr. Dement — definitely the most accurate and scientifically based work I’ve seen on how to get a good night’s sleep.

  3. James Pegram says:

    It’s definitely more about the quality of the sleep than the quantity. I’d much prefer to get 5 hours of deep uninterrupted sleep vs. 8-10 hours of restless sleep anytime.

  4. Matt says:

    Recently I started eating one piece of fruit before going to bed (about 15-30 minutes before) and found I would wake up feeling refreshed after only 6 hours of sleep instead of my normal 8.

    I discontinued it because I don’t really need the extra time right now. Usually I go to sleep about 10:30 and if I wake up at 4:30 I just waste that time until it’s time for work.

    Give it a try for a few days and see if it works for you too.

  5. Ecartman says:

    Wow several things that don’t work for me in here.
    1. open window, no thanks my sinus wouldn’t put up with it, and as for air refresher? Not sure what that is.
    2. No exercise before bed, this one really screws me up. Yes exercise , a lot if you can, but do it upon waking or by mid day. If I work out any before bedtime, sleep won’t come for me.
    3. No coffee after noon for me, but I drink 3-4 cups upon awakening.
    4. I never noticed a difference with reading a well chosen book, or watching a well chosen TV show before bed. In both the theme shouldn’t be exciting, but as the author says relaxing.
    5. do something exciting upon awakening, I have a group I correspond with online we discuss the day, politics, religion. Get the blood flowing. Yeah being a little groggy happens, but after a few minutes its gone.
    I never look for waking up refreshed I wait an hour to see how I’m doing or wait till the end of the day and see how I feel, and adjust sleep accordingly.
    My normal sleep hours are 10 pm to 2:30 am for years now. I keep very close watch on my health as I am diabetic. My doctor and I are both satisfied with my health. Good Luck, I wish you pleasant dreams.

  6. Y.Graf says:

    Yes, you shouldn’t ACTIVELY exercise two hours before the sleep, but taking a walk and some fresh air with it is absolutely fine.
    Half the caffeine that you consumed still exists in your body after six hours, so yes, no coffee after noon is a good idea.
    As for TV, if you stay with some relaxing show that might be OK, just avoid news and thrillers (arent’ those the same these days?)
    Good luck and sweat dreams! :)

  7. Suzy says:

    This is very helpful information. I can & do get by quite well on only six hours of sleep. A few times I have had to do with with a couple of hours, but my body felt on edge the entire day. When it was time to go to sleep it was harder to unwind. Plus, if you get too much sleep it can make you feel all drained. The tips you mentioned help to improve the quality of the sleep, which is a really, really good thing. Thanks!

  8. Tim says:

    For the last three weeks, I’ve been waking up at 5 AM every day so I can accomplish more in the day. I’ve been exercising every morning and I feel better. I’d like to get on a 6 hour schedule, but I am skeptical about how it will affect my mind and body. I’ve studied lucid dreaming as a tool I can use for self-improvement while I’m asleep; sleeping is a waste of time, but is necessary for my body, so I though I’d use that time to try new things.

    My concern with sleeping six hours each day is that my mind will not get enough delta sleep, when REM and lucid dreaming occurs, resulting in less than adequate rest for my mind. Last week, I was surprised to wake up one morning after five and a half hours of sleep and feeling full of energy. The whole day I was energized. The next morning I woke up after seven and a half hours of sleep and I was dragging myself the whole day.

    I’m curious if anyone has done experiments to see how a regular six hour sleep schedule affects the mind’s cognitive abilities (critical thinking, creativity, focus), the body’s reaction in everyday living and whether lucid dreaming can be used effectively.

    I’m no expert at lucid dreaming. In fact, I stopped trying it a while ago. I recalled several dreams and I used a dream journal for a while. I gave up after little success and I left it up to my subconscious brain to do the dreaming and brain repair. I believe that my brain needs adequate time (7 hours) to repair itself, but I may try sleeping six hours to see how I feel. The times I’ve slept less than six hours usually ruin my day, just as sleeping more than 10 hours will ruin my day.

    As a college student, I constantly face the challenge of balancing quality and amount of sleep with fun. Last year (my freshman year), I would constanly go to bed from 12:30 to 2:30 every day, then sleep till 7:30 on early class days or as late as 1 on weekends. I never felt rested, it was terrible. This year, my friends and I are doing a little better job, going to bed from 12 to 1:30 and waking up from 8 to 10. This (combined with a better schedule) has allowed me to continue working out in the mornings (I habit I started these last 2 summers, but could not continue at school last year), and I feel much more rested and alert overall. I still need a little caffeine boost in the morning, but who doesn’t? If only I could start drinking coffee instead of energy drinks and diet Pepsi Max…

  12. Sleeping is so hard for me. I find not drinking caffeine after lunch to be the most beneficial. After that, I would say exercise helps me fall asleep the quickest.

  13. kenneth tung says:

    some times no work.

  14. gmpicket says:

    I cut caffeine out of my life a year ago this month, but it hasn’t reduced the number of hours that I sleep. I just sleep like a rock now, but still the same 8 to 9 hours.

    I’ve spent the past three months working on getting up earlier. I’ve had some success – I now get up 2 hours earlier than I used to – but I also go to bed now two hours earlier than I used to. I still sleep 8 to 9 hours.

    My Dad at age 65 still sleeps 8 to 9 hours per night, like a rock, so getting by on fewer hours of sleep is probably never going to work for me. Total bummer; I would love to be able to get by on 7 hours of sleep.

  15. Sara Lynn says:

    I am a health and fitness coach and spend a reasonable amount of time talking to clients about sleep and weightloss. It is so true that 8 hours of sleep is worthless if you actually aren’t in a deep sleep. Metabolism just doesn’t “cut the mustard” if we are sluggish! Thanks for a great TIP!

  16. Tina Fukuchi says:

    I agree that quality of sleep is more important. I also found that whenever I am stressed or am thinking about work before I go to sleep, I tend to not be able to sleep. Doing something relaxing is especially useful.

  36. It is tough to get used to less hours of sleep but as the article says, slow and steady is the way to go. You need to give your body time to adjust to the changes you are making. If you stay on a program, your body will cope with the changes and eventually evolve to require less sleep.

  43. Sleeping less is not a problem for most people, most people need to sleep more. I know a man that slept at most 2 hours a night for a year and a half. After a while, he started hallucinating and having serious mental problems. Eventually, it will catch up with you.

  44. Silver says:

    “but to be alert, happy and productive during the day, the vast majority of people in this nation need to sleep more, not less”

    … I honestly have to disagree on this one.
    Up until I was about 16, I slept about 4 1/2 hours a night.
    I would be fully alert and wide awake whilst everyone else seemed zombified and tired. However, I too ended up becoming zombified and tired AFTER the age of 16 as I began sleeping much, much less. (2-3hrs a night)

    Now I sleep more. Anywhere from 6-8. At 6hrs I feel more refreshed than 8. And anything after 8, and I’m tired all day.
    Buuut you wanna know a trick to wake up more refreshed?
    Eliminate caffeine altogether.
    I noticed lately I’ve been sleeping MUCH better after a switch from soda to Kool Aid, and so I suspect the elimination of caffeine to be the convict here.

    :) Peace.

    everything is fine but to practice. i read a quote in a hospital saying “if you don’t find time to exercise you need to find time for your illness”. nothing comes without practice. the idea was great. lets make an effort to start. everything will be fine.

    I have the WEIRDEST schedule. I stay up for 32 hours, then sleep for 16 hours. still sleep the same amount, but get the whole week done in one go.

    my body’s been breaking though (its been going on for 10 months), back aches, weakness, irritability, sensitivity blabl blab, bob law.

    when i go to sleep after 32 hours, its the best feeling in the world, better than any other feeling i can ever have, maybe thats what i look for.
    I HOPE i dont die early.

  56. The “key” message here is QUALITY OVER QUANTITY.
    “How” all depends on your body, mind & genetics.

    Some points to achieve quality sleep that have helped me are:
    a. Get at least an hour of sunlight per day.
    b. Exercise to spike your core temp,
    c. Follow a consistent “sleep time” and “wake time”,
    d. Power nap / meditate during the day

    I always sleep with black out curtains and a hot-water humidifier in the room. I never watch TV or eat before going to sleep.

  61. Zach Smith says:

    The best possible way to achieve better quality of sleep is to ensure that your bedroom is at its most comfortable state. Make sure your room’s temperature is just right and it is free from clutter. Also pick the most comfortable mattress. The right mattress varies from one person to another. Therefore, if you are buying a new mattress, you should personally identify your sleep needs. Go to the mattress store and ask for comfort risk-free trial so you can test the mattress before sealing the deal. Remember that you are going to use your mattress for the next 10 years or so. Put a little more effort in deciding the right one.

I don’t really have any problems with less sleep, and in fact we do grinding exercise workouts in the morning also. Any tips on how to make my sleep feel better or longer?

  73. student says:

    Just thought I should put this out there. How you feel on a certain day depends on the sleep you got 2 nights before not the night before. If you are feeling bad one day chances are that you didn’t get enough sleep 2 nights before. That is the way our bodies are programmed. If you have something to do a certain day it is important you get enough sleep 2 nights before. So, if Monday you got 7 hours of sleep and Tuesday you got 5 you may feel great on Tuesday but once Wednesday comes around you will be crawling out of bed with 7.

  74. Shawn James says:

    Matt’s comment from August 2007 is hilarious. But in all seriousness, consider napping if you’re not happy with your sleep. Like Y. Graf says, it’s not just about the quantity of sleep, but the quality. Some think that sleeping more is the answer. In reality, if you sleep too much, you actually increase your risk for migraine headaches (trust me, I’ve been there). Aim for 8 hours, but take less if you are able to sneak away from the desk and have a quick 20-minute nap. More and more research is being published to support that this actually helps keep you alert and energized.

  86. Zak says:

    The reason you make feel more sleepy after 9 hours of sleep compared to 4,8 or 12 hours is due to the cycle of sleep. If you wake up in deep sleep which is at 2-3, 5-6, 9-10 hours, you will feel quite fatigued. But if you awake with the 4 hour interval you will feel much more awake. 

    If you have to get up at 6am and it’s 12pm, head to bed so you’ll have about 4 hours sleep (around 1.30-1.45)

    Who said well written? It is riddled with grammatical errors that should make one question the legitimacy of the article (and I am no english nazi). That being said, the information seems accurate, albeit common sense. I would argue about the soft limit of 1hr less sleep that is given. I can function on 5.5hr no problem right now and am working towards better. I do not keep a regular sleep schedule but that is just me. I would say if you are serious about this, just commit to your goal and use trial and error to get there. That is what I have done. Why there are religious references below I do not know, that is not the same topic. Also 2 weeks, 40 days, whatever people say it takes to form a habit is not accurate. It is not entirely wrong, but most reputable studies have shown a range, and a wide one at that. 10-150 days possibly? I do not recall so that number is not exact but should be within the ballpark.
