Information List of Polyphasic Sleep

Information List of Polyphasic Sleep

Following up on the post 90 Minutes Sleep Cycle, I found out there are couple of sites and resources that talk about this sleeping hack. Technically, it is called Polyphasic Sleep. From Wikipedia, the definition is:

… Polyphasic sleep is a sleep pattern specification intended to compress sleep time to 2-5 hours daily. This is achieved by spreading out sleep into short (around 20-45 minute) naps throughout the day. This allows for more waking hours with relatively high alertness…

A while ago, Kuro5hin has a featured article titled Uberman’s sleep schedule. Ever since the article has been released, there are a lot of interest on polyphasic sleep – discussions are everywhere.

There are also attempts on testing and experiencing such method. Like recently in UberSleep.com, Nick Busey shows his efforts and experience on Polyphasic Sleep. Some people reported positively on such method, however some has bad experience on it:

… I spent 3 weeks attempting to adapt to the Uberman schedule, the major cause of my lack of function by the end was due to the slip up with the naps. My body never really had a chance when I gave it mixed signals as to when it could get sleep. I had a fair mix of good and bad days over the three weeks, the most depressing was the last week where I felt I was going backwards, not forward. Too many slip-ups that week left me disorientated and knackered. Before then, the first two weeks seemed much better, probably because my body was using up my energy reserves.

I may try the schedule again when I can dedicate a month to adapting. I am disappointed it did not work for me this time, what I shall concentrate on now is making sure I utilize my time effectively rather than trying to grab more.

Currently I am classified this as good to know, do not implement it yet. My concern of such method is the health issue associating to it. Does anyone have any information on this?

10 Benefits of Sleeping Naked You Probably Didn’t Know

10 Benefits of Sleeping Naked You Probably Didn’t Know

Sleeping is one of the most important things we do every night.

Getting the right amount of sleep has an untold number of health benefits and not getting enough sleep is a serious problem in many countries around the world.

So you should have heard of the many benefits of getting adequate sleep, but did you know that you can get additional benefits by sleeping naked?

Here are some benefits of sleeping in the nude:

Video Summary

1. It is easier.

When you don’t have to worry about sleeping in clothes, things start to get easier. You don’t have to buy pajamas, which can save you money. You have less clothes to wash and less clothes to put away. You may have to clean your bed sheets more often, but not nearly as often as you’d have to wash your pajamas when you run out.

2. It forces you to be ready to go more often.

Some people get off of work, change into their pajamas, and use this as an excuse to stay home the rest of the evening. This can lead to a more sedentary lifestyle, which has been attributed to things like weight gain.[1] When you keep your regular clothes on, you tend to go out more often and that’s a good thing.

3. It can make you feel happier and more free.

Just imagine the feeling of laying in bed naked. You’re free of your pants and underwear. Women, you’re not wearing a constrictive bra. It’s just you sandwiched between two cool sheets. The feeling just makes you want to smile and it makes you feel more free. Everyone can use that kind of good feeling every now and then, and it may even help you be happier as a person.

4. Skin-on-skin contact is the best.

    If you’re married, or living with your significant other, sleeping naked gives a greater chance of skin-on-skin contact, especially when it comes to cuddling. This kind of contact can also lead to a more active sex life. All of this releases copious amounts of oxytocin, which is the neurotransmitter that helps you feel those good feelings about your significant other.[2]

    5. It could lead to better sleep.

    Let’s revisit the scenario I described above. There are no drawstrings or clothes getting tangled in sheets. You don’t have to worry about shirts getting twisted. All of these distractions go away when you sleep naked and it may help you get better, deeper sleep. You don’t need science to tell you that better, deeper sleep only helps you be healthier.

    6. It can help your skin.

    For once your body gets to breathe. Your private parts, armpits, and feet are generally restricted all day and are often covered by multiple layers, even in the summer time. Give those parts a chance to air out and breathe. This can lower the risk of skin diseases, like athlete’s foot, that result from wet, restricted skin.[3]

    7. It helps you regulate your cortisol.

    Cortisol is a very strange chemical in the body but it can do a lot of damage. When you sleep naked, it helps keep your body temperature at the optimal ranges so your body can better create cortisol. If you sleep overheated your cortisol levels tend to stay high, even after you wake up. This can lead to increased anxiety, cravings for bad food, weight gain, and more terrible things.[4] Sleep naked so you can keep your body temperature down and sleep well so your body can properly produce and regulate cortisol.

    8. It balances your melatonin and growth hormone.

    Continuing along that same vein, keeping your sleeping environment below 70 degrees (F) every night can help your body regulate its melatonin and growth hormone levels. These chemicals help the body do things like prevent aging and are essential to good health. When you sleep in clothes, your body heats up and prevents effective use of these hormones. In other words, sleeping with clothes on makes you grow old faster.

    9. It can keep your sex organs happier.

    For men, the cooler sleeping conditions allows your testes to remain at a cooler temperature. This helps keep your sperm healthy and your reproductive systems functioning as normal. For women, the cooler and more airy sleeping conditions can actually help prevent yeast infections. Yeast grows better in warm, moist conditions.[5] When it’s cooler and dryer, the growth of yeast is prevented.

    10. Sleeping in the summer is more bearable.

      Summertime is a tricky time to get good sleep. If you don’t have air conditioning, then you may find your bedroom a bit stuffy at night.

      Shedding those bedtime clothes can help the bedroom feel more comfortable. You may even be able to turn the A/C off on those cooler nights, which can save you a few bucks on your electricity bill.

      Don’t wake up drenched in sweat again because your thermostat is downstairs and the hot air expands up to your bedroom where the thermostat can’t read the warm temperatures.

      Sleep well with your naked body!

      With these tips in mind, it’s time to start taking off your clothes at night!

      Of course, there are times where clothes are preferable. If you are ill or it’s cold outside, then you should sleep with clothes on to help you stay warm and prevent further illness. Otherwise, go commando!
