Sleep A Bit Less, Live A Bit Longer, Or So They Say

Tired? Me too. I could do with a couple of extra hours sleep per night. Or could I?

I’ve always found 8 and a 1/2 hours sleep to be the optimum, but a survey done a few years back by a couple of researchers in Japan revealed that people who sleep roughly 7 hours a night live longer than those who sleep more. They found that those who slept 8 hours a night had a “significantly higher mortality than those who slept 7 hours” with mortality risks increasing the longer the snooze. Moving in the other direction, it was only when people reported having 4 hours sleep or less a night that increased mortality was again noted.

So we might be better off with 7 hours sleep a night, but there are some animals out there who need far less than that and some that need far more. The beloved giraffe is the shortest sleeper amongst mammals. They sleep only 1.9 hours a night on average, and often that is taken in smaller naps. As well as needing an incredibly short sleep per night, they mostly sleep standing up, twisting their necks back and resting their heads on their backs.

If just thinking about that makes you feel sleepy, you must be more like the Brown Bat that sleeps a whopping 19.9 hours a night. Well, I say a night but really that amounts to all of the night and half of the day as well. AND, not only do they spend all that time asleep, they top it off with a 6 month hibernation each year. Sensible creatures.

Here’s a sample of other animal species and their average snooze times:

Squirrel 14.9 hours

Rat 12.6 hours

Cat 12.1 hours

Hedgehog 10.1 hours

Pig 7.8 hours

Goat 5.3 hours

Elephant 3.5 hours

Horse 2.9 hours

Interesting huh? Now I’m off to catch some z’s myself.

‘Night, ‘night.

    This is really interesting, but does Quality vs Quantity come into affect here, at least as far as humans go? I mean, sleeping five hours a night would eventually catch up to us, right? I’m not sure, of course, as I wasn’t the one doing the research. So anyways… good post. =)

    I agree about the quality versus quantity. 4 hours of deep, restful sleep can be far more invigorating than 7 hours of light sleep. At any rate, I strive for 7 hours a night. I don’t always succeed, but what are goals for if we don’t try? Good post!

      There must be loads of other factors involved, of which the amount of sleep is only one. Otherwise it doesn’t correlate to other mammals sleep/mortality patterns, and we’re not physiologically much different from them.

    That’s interesting, about sleep time. I’ve wondered if you lose weight if you sleep under colder conditions. I mean, without too much cover, or heating. Your body should tend to work harder to keep you warm, as you’re burning more energy. Anyhow, I tend to sleep on average, not more than 7.5 hours, waking early, about 5.30 am, and getting up, at very least by 6 am. I sleep with very light cover, in the hot weather, no cover and a fan. Perhaps that is why I’m a light 120 -130 pounds, never ever crossed 140, even when feeding to extreme on ships or offshore rigs.
    It seems to suggest sleeping under too warm conditions, shuts down your metabolic system, so you don’t lose weight like that. Anyhow, I’m 75 now, but have lost so much sleep on ships and drilling rigs, often going days with very little sleep, or none.

Besides completely taking away my stomach pain, I also started needing less sleep and was able to function for longer on less sleep.

    Come to think of it, the Japanese researchers make sense to claim that mortality risk rate increases with sleeping time. Afterall, humans are prone to stop breathing when we sleep. However, the title of this post, without reading through, I would have agreed with you fully. Sleeping less means freeing up more time in a day. That’s almost the same as saying we do live a bit longer, if we measure our lifespan by how much things we accomplished rather than by the minutes and seconds.

    Live longer, maybe, but according to new research, you won’t be as attractive. I’m so confused. Sleep more, wake up pretty, sleep less, wake up with a few more years added to my life but settle for not being “hot.” Who knows what to do? Interesting post, and thank you!

      Hahaha – live longer and be ugly. Not many of us would opt for that, at least not until the point when it’s too late for ‘looks’ anyway.

    I think the more you sleep the better, you feel better and you look better. They say sleep makes you more beautiful:)

    I think there was some research proving that if you regularly sleep 8+ hours your aging process is slower. So you you might live a shorter life but you will look better:)

    For me 4 hours is optimal. If the shorter sleep cycle seems to be catching up to me, I may take an occassional power nap with a heavy book in that wakes me when it drops to the floor.

    I am also intrigued to learn that an elephant requires so little sleep yet manages to live for so many years.

    Great post! Thanks for sharing.

    It has also been rumoured that every hour before midnight counts as 2. Hmmm….

    19.9 hours of sleep sounds like pure bliss to me!

    I think the cat’s sleep hours should be listed by “young cat” and “older cat” – like with any of my over 10 year-old cats, they sleep definitely 16+ hours per day and it only gets worse as they age.
    I can’t say the same for humans… at least not any of the older folks I’ve known.
    I think this research makes sense for me… I’ve come to realize that when I get over 8 hours of sleep, it makes me groggy and unmotivated and that could literally sleep the entire day. However, if I get 6-7 hours, I feel much better… less tired.
    I can live on 4-5 hours of sleep, but not for more than 2 nights in a row or I CRASH on day 3… majorly.
    I think our bodies do a fine job of dictating what we need… of course staying up late for some “me time” and then being forced to get up for a job the next day can mask what you’re body would prefer.

    Grr… leave it to me to write “you’re” when it is supposed to be “your” – which is the exact opposite of how most people mess that up. Doh. Apparently I did NOT get my optimal sleep last night! 🙂

    I am blessed (yes, blessed) to be able to sleep until my eyes wake up. I find that to be usually between 8-9 hours. Of course, when it’s cold outside, it takes me longer. Sleep is a wonderful thing.
