様態の副詞

you probably have a love/hate relationship with sleep. You love the way it makes you feel,

程度の副詞

but you hate that it seems to waste so much time,

or maybe it just doesn't come easily to you. As someone who has struggled with and ultimately conquered severe sleep onset insomnia,

Dr. Jubbal, MedSchoolInsiders.com.  New research has illustrated just how important sleep is,

this is the part where you moan in annoyance as you've been told this time and time again. I won't belabor the point,

but I do want to leave you with three facts about the importance of sleep that are too interesting to omit.

First, drowsy driving accounts for more accidents than drunk driving or driving under the influence of other substances combined.

Second, you can function well without food for several weeks, without water for several days,

but you experience the most rapid decline in function without sleep. And third, despite millions of years of evolution,

we still spend one-third of our lives asleep

despite it being extremely costly. Think about it,

it must be necessary if evolution hasn't prioritized finding food, or finding a mate, or simply not being vulnerable to predation.

For more interesting sleep facts, check out the  Peter Attia The Drive episode with Dr. Matthew Walker.

Now, let's address your difficulty with getting good quality sleep or getting enough sleep, and don't tell me you are too busy to

prioritize your sleep.  As someone who is actively growing two YouTube channels,

and growing three separate businesses while still getting seven to eight hours of sleep,

I'll be the first to say that it's less about you being busy and more about you being inefficient with your time.

A lot of viewers have asked me how I'm so productive and I'll be releasing a video about my strategies on the Kevin Jubbal, M.D. YouTube channel.

The discussion on sleep optimization has recently focused heavily on one's chronotype. As humans, or rather organisms on planet earth,

we run on a circadian rhythm. This 24-hour internal clock coordinates various physiologic functions related to sleep and wakefulness

from hormone levels to body temperature and much more. Approximately 40% of people have an advanced sleep chronotype,

meaning that they are morning people or early risers.

Approximately 30 percent of the population has a delayed sleep chronotype,

meaning they are night owls. The other 30% falls somewhere in the middle.

As Dr. Walker writes in his book Why We Sleep, night owls are not owls by choice.

They are bound to a delayed schedule by unavoidable DNA hardwiring.

but rather their genetic fate.  Chronotypes actually change over the course of your life.

Infants are predisposed to early chronotypes, teenagers are delayed chronotypes,

and once you pass the age of 50 or 60, you trend towards early again. Your chronotype in adulthood is set in your early

20's and generally stays constant. Greater understanding of chronotypes is awesome, but it comes with good and bad news.

The good news is that it's backed by science and we understand that being a night owl doesn't mean you're lazy,

It just means you have a delayed sleep chronotype.

If you have a delayed sleep chronotype, there are even data suggesting your prefrontal cortex,

which is the part most important for your higher-level cognition won't function optimally when you're forced to wake up early.

But here's the bad news, the world doesn't care about your chronotype.

I don't consider myself an early bird, but I still had to wake up at 3:30 a.m

hundreds of days in a row while doing plastic surgery. The hospital and operating room didn't slow down just because I'm not a morning person.

That being said, all hope is not lost. In my first video about sleep optimization,

which now has over five million views, I explained how I grew to love waking up early

And in this video, I'll teach you the techniques to sleep like a pro regardless of your chronotype. When we speak about optimizing sleep,

we don't simply mean getting more shut-eye.

Surely, you've experienced nights where you slept for eight hours and felt great in the morning, and other nights where you slept eight hours

The reason is that there are four pillars of sleep and sleep duration is only one of them. The four pillars are:

First, Sleep Depth and Quality. This is reflected in the quality of a sleep waves,

meaning alpha, beta, delta, theta waves, sleep spindles, k complexes, etc.

These are measured on an EEG.  Number two, Sleep Duration. How long are you sleeping? For most adults,

this should be between seven to nine hours.

Number three, Continuity. Is your sleep continuous or interrupted, and number four, Regularity.

Falling asleep and waking up at the same time each day.

Falling short in any one of these four pillars will result in sub-optimal sleep and negative effects on your restfulness and overall health.

For example, say you have two scenarios where you sleep eight hours each night, on one night,

you sleep eight hours continuously without interruption. On the other night, you sleep the same amount of time

but over a longer nine hours with multiple small interruptions. The continuous sleep will result in far better restfulness.

Keep these four pillars in mind as we work through the five steps in optimizing your sleep.

There is no one single magic bullet and only you can decide how much you are willing to

prioritize your sleep. Some of these changes will come easier than others. That being said, if you follow these instructions,

you should experience a drastic improvement in how rested you feel.

First, determine what time you have to wake up in order to get to work or school on time, work backwards from there,

accounting for how long it takes to commute and get ready in the morning.

You should plan for seven to nine hours of sleep each night. By doing this exercise,

you will set up your target bed and wake times. This may not be optimized for your chronotype,

but setting these times will still be highly beneficial in improving the quality of your sleep.

As tempting as it is, do not deprive your sleep during the week only to binge and catch up on the weekends. This behavior

resulting in reduced sleep pressure, meaning it's harder for you to fall asleep and stick to your schedule come Monday.

This is arguably the most difficult step to implement,

but I have personally found it the most powerful. If there are days that you can go into work or school later,

I still suggest you sleep and wake up at your scheduled times.

Use that extra time in the morning to get studying or work done. This benefits your sleep schedule and you might as well start the

day off with a win. It's not uncommon to stay up late on Fridays and Saturdays for social events throwing off your sleep schedule,

I've done that too from time to time. However, during particularly stressful periods,

like when I was doing plastic surgery, plus growing Med School Insiders, plus building and running a biomedical incubator,

I prioritized sleep over social events. I wasn't writing off socializing and partying forever,

I simply was in a season in my life where I need it to grind hard.

If you're serious about not feeling tired all the time, optimizing your bedroom should not be taken lightly.

Let's talk about lighting, sound, and temperature. In terms of lighting, you want your bedroom as dark as possible at night.

I bought blackout curtains in college mostly because my apartment was poorly insulated

but I soon realized the benefits of sleeping in complete darkness.

This also means turning off any lights from electronics that illuminate your room.

I placed electrical tape on various battery chargers and electronics in my bedroom that gave off even dim light. The results were

surprisingly drastic. For temperature, understand that your hypothalamus

approximately 2 degrees Fahrenheit for sleep. Ever notice how it's terribly difficult to fall asleep in a hot room? To help your body get into

it helps to keep the room cool with most experts agreeing that the mid-60s are a good temperature to aim for. Or you can

do what I do, which is wear very little when going to sleep and use light bedding.

This means I can keep the room in the low 70s and still sleep like a baby. With regards to noise,

most people don't realize that noises that don't wake them up consciously still affect their sleep quality.

Remember continuity and depth from the four pillars?

I like to use a fan as white noise in my room, but you can also buy a white noise generator
