For instance, during periods of stress or illness, you may feel an increased need for sleep. But although sleep needs differ over time and from person to person, experts typically recommend that. Until sleep debt is paid back, it’s fine to sleep longer than usual; one study found that just one 10-hour sleep session significantly improved cognitive function following five nights of sleep. How Much Sleep Is Too Much?

Sleep needs can vary from person to person, but in general, experts recommend that healthy adults get an average of 7 to 9 hours per night of shuteye. If you regularly need more than 8 or 9 hours of sleep per night to feel reste. The vast majority of people—approximately 70%—need between six and nine hours of sleep a night. If you’re someone who needs more than nine hours on a regular basis, you might want to think about how restful your sleep is and if it is of good quality. An infant may need up to 17 hours of sleep each day, while an older adult may get by on just 7 hours of sleep a night.

But an age-based guideline is strictly that — a. No matter which age group you are, if you sleep more hours than the upper limit displayed in the Not Recommended column in the chart below, then you are sleeping too much. Age. Recommended.

May Be Appropriate. Not Recommended. 0-3 months. 14-17 hours.

11-13 hours. 18-19 hours. You may find you need 7 hours of sleep in your 20s, and 8 hours—or 6.5—in your 50s or 60s.

Newborns tend to sleep a lot. Some babies sleep for 16 to 18 hours each day, waking up only for short breaks to eat and have a diaper change. You might wonder if they’re sleeping too much.

Generally speaking, an adult who is consistently sleeping ten or more hours per night is probably sleeping too much and should talk to their doctor. In general, doctors agree that most people should get between seven and nine hours of sleep a night. If you’re an adult and you regularly get 10 or more hours of sleep a night (and you aren’t.

  • Psychiatry is so complicated because each person is different. I was in and out of hospital for 12 years and suffered chronic insomnia ( days and days without sleep while in a state of suicidal depression) before an effective medication cocktail was found. I am bipolar and I was so grateful and ever so slowly I got my life back. I am at my best when I sleep 9-10 hours per night. Any less and I begin to have bad anxiety, depressive symptoms or hyper heightened mood. It sucks to have to spend half my life in bed but I’m not complaining. 12 years of insomnia was a fate worse than death. The illness was so severe that I almost died a few times and I lived in a hell of psychic-emotional pain. Now, a lot of sleep along with the medication, means I wake up alert and energetic. I manage to pile a lot of activity in my days. Of course, I don’t have children.

  • I drink coffee until 11:00pm nightly. I have the TV on to help me shut off my thoughts and go to sleep. I don’t formally excesize. I sleep from five to eight hours a night. I should be dead by now.

  • I am so going to try this.

    Back in high school days 2014/15 there i used to wake up and no matter how i felt inside or the environment i kept feeling like my brain is still asleep. (Didn’t know i had Bipolar 2)
    One day i was electrocuted, more like shocked and all lights went on and i did this for sometime.

    I still feel cloudy when i’m off the hypomania parts of this and try to wake up with intense work outs. I hope this and what i’ve been doing works.

    Dr. Mark You’ve been heaven sent since i found your channel earlier this year. God Bless you in 1000 folds for the very needed help and information you share with people like me who really need it.

  • I would love to do this, i just downloaded the file but then i realised how i always have terrible heartburns and breathing when i stay up too late or no sleep at all, i can only stay up a little late but not too much, ny body system ain’t as strong no more:(

  • I might add, I do walk around like a zombie all day on the day I skip a night of sleep to reset:/ so hoping this means I’m not bipolar since I don’t have more energy.

  • Hii am from india, can u plz suggest me? my mom is 63 having cardiac an diabetes prob, she just got surgery of cellulitis legs two week back she was in pain before surgery and after surgery too for long.. but from 4 days pain had been realise and now after that she is only sleeping.. all the reports r normal like oxigen level, creating,

  • Is it bad if you do this often? I reset my sleep cycle this way frequently, as sometimes I just can’t sleep until it’s daytime, then sleep through my important stuff:(. I was afraid that staying up all night until next bedtime could trigger bipolar disorder (it runs in my family) but I do normally manage to sleep on the second night, just sometimes have to take a sleeping pill to relax.

  • i’ve just been getting 8 hours of sleep then waking up for a few hours and taking hour+ long naps multiple times throughout the day

  • I can’t oversleep or I get an “oversleep headache”. It’s kinda like having a hangover but you didn’t have the fun of getting drunk the night before. If you have it you can’t get rid of it so that means that especially on the weekends I can’t just roll over and go back to sleep too often or I’ll get one. It really sucks.

  • I really need my sleep. If I have a good night’s sleep, I wake up restored and renewed. In the evening I become fatigued and weary, and I have negative thoughts, but a good night’s sleep can make all the difference in my thoughts.

  • My goal for the last few weeks has been to be in my bed at 2 am and up by 11:30 am (I work 2nd shift). But even that is hard. I’m in bed at 2 am every night but I usually dont actually get out of bed till about 1 30 pm lately because I have insomnia and it takes me 1-3 hrs a night to fall asleep. I am losing so much time every day and it sucks… And on the few days where I do manage to yank my ass out of bed at 11:30am, if I didnt get at least 8 hrs, preferably 9, my focus is shit and my lower back aches all day. Maybe someday I’ll get this shit down… Is there anyone out there in the comments with similar problems?

  • I’m amazed to hear people with depression complaining about sleeping too much! With my depression Im considered extremely lucky if I get 5 hours of sleep (and that’s with Xanax too)

  • This sounds like such an interesting therapy! I’m really interested in trying it! I have bipolar type 2 and deal with long periods of depression that are the main issue in my long term stability. I’ll be looking into this and talking to my doctor about if this is something I can try! Thanks!!

  • As much as I am able to, I try to not wake up to an alarm, even for work. Learned it from Jeff Bezos. It’s nice cause u get fewer hrs in the day but they are much higher quality. Would highly recommend.

  • Wow this was great. Never heard of this, but as my depression (I think) came after working abroad and having my rhythms mess up, I think this could really help me. As I’m on the way out of my depressive symptoms, I think I’ll give this a go.

  • I currently can’t sleep and it’s 4 am… again ��, I’ve been sleeping till 2 pm recently (I’m 15) and I’ve been setting alarms for around 11am and I just can’t get out, I’m so comfy and warm that I accidentally fall back asleep ������

  • Hi, doctor… I am taking paraxetin 25 mg for depression. What time of the day I should take it?? Also I have problem of overthinking early in the morning even after getting good night sleep,what should I take to or do to control it?? I took pregabalin 25 mg for this & it helps… should I continue it & what dose??

  • in last year i have been sleeping to much with a nap, and i have high blood pressure, i feel i do have mental problem, cause if your sleeping more,your not coping with everyday life, and i learn the hard way that in the end it will all catch up to you!!!

  • what about the quality of sleep was that taken into acocunt. you can have 9 hourse of sleep but if that sleep is super bad quality and the person that had 6 hourse had prime quality of sleep

  • So I used to try to sleep 8 hours in college but I couldn’t really function right if I did that. I had to have 10 hours. Now I sleep about 9 hours. Is that bad?

  • What do you think of triple tharaphy. Wake theraphy, light theraphy and sleep phase advance pheraphy. The protocal you gave me does not mention about sleep phase advance theraphy. And what do you think about lithium. Do you think it really affect circadian rhythm? And what about lamictal as well?


  • show this to every parent who thinks sending their kids to bed 4 hours before the recommended time for their age limit is gonna solve every little problem

  • It’s a good thing I don’t consistently sleep for any amount of time, eh? Some nights I get six hours, some eight, some ten, never at the same time of day. What a joy it is. Ech.

  • Hi Dr. Tracey, I’m curious about doing wake therapy when having to drive to work or anywhere during those 36 hours. I’ve read studies that indicate that going without sleep is like driving over the limit. What are your thoughts on that?

  • I had heard or read somewhere that people with mental illnesses are more likely to be “night owls.” It is true for me, even when I was quite young, before I was ever diagnosed, I gravitated to staying up very late or into the wee hours, then sleeping quite late. Now I’m totally upside down.:-/

  • Thank you Pastor John, you have answered the question succintly using God’s word. It is amazing how God uses men to help us understand what he expects from us as we serve in His kingdom.
