The Science Behind a Good Night's Sleep

The Science Behind a Good Night's Sleep

????

We all know sleep is vital, so why do many of us still find it so difficult to prioritize? CNN Chief Medical Correspondent Dr. Sanjay Gupta speaks with sleep scientist Rebecca Robbins about why we sleep in the first place and how to ensure we get a good night's rest. And neurologist Ying-Hui Fu explores the latest research surrounding sleep, including what regulates the amount of sleep we actually need and what role genetics might play. We also meet Cliff Luther, a man who only needs about four hours of sleep a night yet wakes just as well rested as the rest of us. What's his secret? This episode originally aired in June 2021.

Thank You for EVERYTHING!!!
@ARFirstRaptor2011 Says:
Hi Sanjay, hope you all are doing well. I have a question: For past few months I am sleeping 3hrs 30 mins in the day and 3hrs 30 mins in the night due taking care of old parents and my work schedule. I don't see any issues, I feel fresh and okay. Is this good for the human system? Also I can't go to sleep when it is total silence, I had to listen to some universe documentary and when my wife stops it, subconsciously I wake up. Please advise

I exercise regularly, eat healthy and stay at chart weight. I don't have trouble falling asleep (anywhere) and stay asleep for the duration, dreams and all. I would be miserable if I had to be in a bed for eight hours straight. 4-5 hours is enough for me, anything more and I'm groggy

I have bought different mattresses and they all seem to be too hot even when I leave the thermostat at 68 degrees my back it's always hot. I recently went to El Salvador and I slept like a baby and what I noticed was that my back was never hot during the two weeks that I stayed there, so I'm convinced now that in my case whatever the material they fill up the mattresses with in El Salvador it's definitely much cooler than whatever it's they use in the States and it definitely helped me sleep better.

Remember when Joe Rogan made an ass of this goofball for being complacent in the lies and wild conspiracy theories that CNN were spreading about Joe and Ivermectin?

Actual doctor: here are extremely compelling and well researched reasons why you need to sleep well to not die young and miserable from long term stress disorders. Employers: lol, lmao, wake up at 5 AM and commute two hours through heavy traffic, work 10 hours, then commute two hours back or get fired loser.

Blue light from light bulbs is the No1 reason people cannot fall asleep in our modern age. In the old days of candle light and fires, there was no blue light produced and so the body could enter sleep mode unhindered. Blue light starts when the Sun comes up and gives us the wake up call accept that today with lights, computers and cell phones, this blue light is always present around us and prevents the body from producing Melatonin. Get your sun glasses that remove the blue light spectrum. Non blue light light bulbs. When you go the the bathroom at 2AM, do not turn on any lights or this will cost you minimum 30 minutes of sleep lag. These are all known facts that modern day medicine does not want you to know.

About 30 years ago, I was reading a very old book (at least 300 years old) and I noticed something very strange in it.. they spoke of a "second sleep". The night was divided into two halves. First sleep took place from eight to almost midnight. Then the family would get up and many times go over to other people's homes, sew, play music, etc. Then around two in the morning they would go back to bed for "second sleep" till morning... (on a side note, apparently the best time to get pregnant is the beginning of second sleep .. that's what one book said, anyway.) The time that they were awake was referred to as "the watch". This sort of biphasic sleep schedule had gone back through the centuries (at least according to some other books I've read).. it seemed at the dawn of the Industrial Revolution is when "sleeping through the night" became popular. There was just no manual on sleeping for humans throughout time.. I wonder who's getting it right or if we ever really will.

The real science behind getting in a truly good nights sleep is very simple. Don't watch CNN.

I have sleep apnea and also pulmonary hypertension….and the PH, my cardiologist from Stanford told me, was caused by sleep apnea. He is one of the top specialists of lymphedema as well. He could not stress enough how vital a good nights sleep was. And he said at least 7-8 hours, preferably 8.
@hoboryan3455 Says:
I currently suffer from chronic nightmares. I have them EVERY night without fail. I have developed a phobia sort of around going to bed so I guess I have insomnia

We're all different. I'm 70 years old and sleep on the softest bed Temperpedic makes with the electric blanket on very warm if the room is cool and a cat and a dog with me. I sleep really well and far too much. I love sleeping and lucid dreaming. I fill my stomach and use THC before turning off the light and turning on the white noise. My wife and I (40 years) sleep in separate beds as she prefers to sleep cool.
@TheHypnotstCollector Says:
Clown science. Good sleep depends on your Societal Exprecations. and Unethical decsions might occur if you didn't sleep properly. Is that Dick Cheney's problem? The Donalds? Lets go Brandon's? And Machismo problems with being awake. And sleep needs to be a Crucial Part of The Day....Minute 9:00..... Don't do anything but sleep in the bedroom.! Minute 10:40. Well, don't go to Med School! Don't work in the Emergency Room. This is Woke Logic
@samwisegamgee289 Says:
for years i have turned off the heat in my bedroom and kept the window opened till i am ready for bed its especially good in the winter where the room is cold and nothing sleeps better than getting under cover (i live on the 4th floor so unless they want to climb the wall which is in plain view i am safe)
@lindaelarde2692 Says:
I have heard on neuroscientist, Andrew Huberman's, podcast that non sleep deep rest (NSDR) can have some beneficial effects to ameliorate schedules that make 8 hour sleep at night to be challenging. Is this, like meditation, supportive of healthy rest?
@antoanetapateva4992 Says:
Good night's sleeps each and every night - matter of good, iron health by nature, lack of these abilities - typical for insomniacs, I.e. very sick persons by nature! Very important criteria! People are born not equal in terms of inborn health matters!

@brothermine2292 Says:
1. The advice about lowering the bedroom temperature below 70F raises obvious questions about blankets... how warm should the blanket be, and which parts of the body should the blanket cover? 2. I wake up many times each night, and my active mind is what makes it hard to fall asleep. My solution to help me fall asleep (or fall back to sleep) is to listen to fiction audiobooks or the soundtracks of tv episode reruns. It's been very effective. The point is to listen to speech that suppresses my own thoughts, but which is not so fascinating that it will keep me awake. Staying awake to hear the entire story is not the goal. When I awaken in the middle of the night, a player app that lets me rewind by swiping backward on a progress bar makes it easy to rewind the story to a position I remember hearing, where I resume the playing to help me fall back to sleep.

I love my dreams. I have been successful with 5-7 hrs sleep I am able to fall to deep sleep quick & lower my heart rate depends on diet & caffeine intake. I tracked on Fitbit. I am sure it will change as I approach my 60s. One key is taking time to meditate & learning to lower heart rate & proper food intake before bed light no sugar, no caffeine after noon. It took me at least six months to get a great nights sleep. This is coming From a bad insomniac in her teens. With nightmares.

Everybody knows Biden, Hilary, Sussman, Fauci, Pelosi, Coomey, Schiff are extremely crooked people. We also know that they are all Bilderbergers. So what does this cult own ? The global media !! Just listen to the activists peddle lies daily. So what is my point then ? This is a war between the Globalist elites, and us. To win this war, is not to watch or listen to these evil people. TURN OFF !!!
