To be frank, I would make an effort to look into why and attempt to rectify. Increasing number of studies showing chronic sleep deprivation may have higher mortality risk than high blood pressure & heart disease. This has become an elevated focus as of late in my field, notorious for lack of sleep (institutional trading). The research behind it is no longer vague.

I have to disagree on sleep. It's not an optional type of thing for me.. brain can't function if too many days at 6 hours. It's a damn curse as I know many have no trouble with less sleep.. I'm destroyed without it. If I go to bed super early (1030pm) then in theory I can be up 430am and be functional, but most nights need 7 solid hours, 8 ideal.

My Father is a Dr. and always felt that some people just do not need a lot of sleep. If you are tired all the time than that is different story.
Would be interested in your findings

i do not sleep much as well. Maybe 5 hours per night sometimes less. Been like that my whole life. Never tired and feel great

No disrespect to your father, but there is far more research on the subject available in this century compared to the previous. Particularly how it affects long-term cardiovascular health. I can certainly understand why he thought so without previous studies to the contrary

The amount and quality of sleep are extremely important to your overall health. When you sleep your body and brain are healing.
Here is a good article by Ben Greenfield.

So what does this have to do with deep sleep?
In a recent 2019 study, researchers found out that the waste removal system of the brain described above (the glymphatic system) is at its peak during deep sleep. The study, published in Science Advances, demonstrated in a mouse model that the waste removal system of the brain functions most efficiently in conjunction with slow-wave electrical activity of the brain that occurs during deep sleep.
This is important due to the reason that the brain accumulates waste as a result of metabolism, which needs to be removed. If this is not happening as it should it can predispose to neurodegenerative diseases such as Alzheimer’s disease, which is associated with the accumulation of amyloid beta and tau proteins in the brain. Therefore, it is likely that getting too little deep sleep deters the glymphatic clearance and causes neurological diseases.
In another ”fresh from the press” article published in Nature Communications (2019), the researchers found a new mechanism involving sleep and its effects on fixing DNA and chromosome damage. The title reads: ”Sleep increases chromosome dynamics to enable reduction of accumulating DNA damage in single neurons.” Sleep has been previously shown to repair DNA double-strand breaks (DSBs) in mice and fruit flies. In this particular study done on live zebrafish, researchers proposed a whole new model on how sleep functions.
The article states that:
”…during wakefulness, chromosome dynamics are low and the number of DSBs is accumulated in neurons. This mechanism suggests that chromosome dynamics can define single sleeping neurons, and that one of the functions of sleep is nuclear maintenance. Therefore the beneficial role of sleep is to increase the chromosome dynamics that are essential for the efficient reduction of the number of DSBs in single neurons.”
These DSBs are increased in the nucleus by both external and internal factors (see picture below).
Still, even when the research on sleep is moving forward and getting more detailed, the ultimate explanation to the question ”why must we sleep” remains without a comprehensive answer. And another question also remains to be answered: why some yogis need very little or no sleep at all.
But before we get all the answers to these two deep questions, let’s move on!

How Deep Sleep Cleanses The Brain & Repairs DNA
Scientists at the University of Virginia found in 2015 a previously unknown connection between the brain and the immune system. Results were published in the highly respected Nature journal. The scientists discovered that the brain contains a lymphatic system (or glymphatic system due to its dependence on glial cells), which is linked to the general immune system. It was previously believed that the brain lacked lymphatic vessels completely.So what does this have to do with deep sleep?

How about Canada .... You get 35% on your dollar, you get to put away your car for 6 months every year and save a ton of milage , When it gets crap we just all take off to Florida and return just in time for a free health care tune up and just as you are, we are continually equally entertained by our retarded prime minister .... all this can be your's and the price is right !!

Thanks.
Great car. Cut my teeth modifying and ripping back roads in one as a teenager.
Sleep is overrated.
Woke up at daybreak this morning...

Apologize as I was part responsible for taking it off-line. Usually I mind my business, but this is something that has really come to my attention over last few years. Scared me into taking it more serious. If it gets just one guy to ask his/her primary for a sleep test referral next checkup, I'd feel good about it. Used to work with an exceptionally talented curves/eurodollar trader that burned out in rather spectacular fashion at the top of his game, all sorts of bizarre health ailments. Most of us thought it was because he was emotionally handling too much size and never left his office. Could afford any health specialist/treatments he desired, low-mid 9-fig wealth by mid 40's. After all said and done, most blame came down to an undiagnosed sleep disorder he'd been dealing with since grad school. Caught up with him quicker due to nature of job. Teaches physics now at his daughters HS.

Anyway, sleep study at hospital in a couple months.
