Biphasic sleep
Postby zill » Tue Sep 22, 2015 1:32 pm
However, in my late twenties, had more and more trouble getting the required full (without a break) 8 hours of sleep (and not for reasons such as work). Recently, what I am experiencing is something strange but very effective in terms of not feeling tired for the rest of the day. That is falling asleep at midnight for about 4 hours, wake up and have breakfast then go back to sleep for another 4 hours or so. At first, I was scared that this was very bad and really wanted to make an effort to reverse this cycle. However, after searching the internet actually found that this was a natural phenomena and actually the way it should be! Note that I am lucky to not have work early in the morning so able to do this. I usually feel really good sleeping this way and never feel tired during the day - and don't feel the need for coffee after the second sleep. It even feels better than sleeping 8 hours straight which does happen on very rare occasions these days. However, I cannot claim to sleep like this every day as sometimes, I might get 6 hours of sleep straight but then not able to fully sleep afterwards, as a result feeling very bad and sleepy throughout the day even after having coffee. I will then have the need for naps as well throughout the day.

Happens to me sometimes as well. How long does it take you to get to sleep again?

Do you need the breakfast to fall back asleep?

What is so random about it? It's startling if you ask me given also that people have done research on it.Bluejay87 wrote:Another great random Zill thread.

Trying to lose weight at the moment so often feeling hungry after waking up at 4am. So yes, otherwise, I will have the feeling of hunger. Sometimes though after a larger dinner don't feel the need for breakfast so early. Will just lie in bed for maybe up to an hour before sleeping again.

In fact, I am now solely going to concentrate on losing weight rather than training for power which is easy for me. Losing weight on the other hand is very hard. Will just be commuting for now plus walks and a weekend ride. It's all going to be about daily calorie deficits. My homework for the next few months is just to be constantly hungry which sounds horrible but at least there isn't the pressure of cycling. After losing the weight, I will then start to train properly for cycling.zill wrote:Not good to be honest. Lost 3kg in 13 weeks by not trying to starve myself.

You only sleep 2 hours at a time? How long break do you get before getting to sleep again?foo on patrol wrote:I don't know what 6hrs continuous sleep is? 2hrs is my limit and has been this way for close to 20yrs, hence the grumpy part.

I'd add some weights or other strength work too.zill wrote:In fact, I am now solely going to concentrate on losing weight rather than training for power which is easy for me.

Old mate I ride with had a diabetic reminder last year, lost 10kg in 6 weeks. Diet and lots of treadmill, no cycling. He's still as weak as a kitten. Looks unhealthy, too.
Mind you, we're in our 50's. Different story in your teens or twenties I think?

Yes, doing some weights at home as well. Cutting my kms back now and just focusing on diet.

your lack of weight loss is common for people who go to bed at midnight.zill wrote:Not good to be honest. Lost 3kg in 13 weeks by not trying to starve myself. So may have to start starving myself to some extent.
you may very well be getting up 4 hours later because of your late night activities. but I digress

The reasons are not elaborated in the literature.tgdavies wrote:Interesting comment -- what's the reason for late nights reducing weight loss?CKinnard wrote:your lack of weight loss is common for people who go to bed at midnight
But it could be
- disruption of any number of endocrine rhythms, especially those reliant on progressive NREM sleep phases, such as growth hormone. Third and forth stage NREM stages are considered essential for adequate recovery from athletic activity.
- expending higher levels of blood sugar between dinner and sleep, and consequent snacking more in that time, especially on unhealthy foods.
- being more fatigued in the morning, and consequently less physically active.
- you burn more fat when you go 12 hours without eating. Those who stay up late tend to snack more regularly.

This can occur in the second phase or period of sleep as described in the opening post.CKinnard wrote:Third and forth stage NREM stages are considered essential for adequate recovery from athletic activity.
If one can control themselves not to over eat than can't see why it's bad to sleep late. However, it does feel pretty bad going to bed on a not very full stomach. If one can get over that than shouldn't be much problems?

The second phase or period you referred to occurred over a 12 hour period of darkness. You are breaking your sleep over a shorter period.zill wrote:This can occur in the second phase or period of sleep as described in the opening post.CKinnard wrote:Third and forth stage NREM stages are considered essential for adequate recovery from athletic activity.

What do you mean?
Break up my sleep into two phases seem to be the only way I can feel energetic the whole day. Sometimes however like today, it took three hours to fall asleep the second time which isn't good. Those are very drowsy three hours.

As for energetic, you want to take a leaf out of the sleeping patterns of the world's best athletes, and their dietary preferences. but you and I have covered this before, and you still seem to be looking for a brand new fancy pants way to get the best out of your body....and mind.
