We have a global sleep deficit crisis particularly for adults. Adults on average are getting less than the recommended 8 hours sleep. Adults are also increasingly reliant on stimulants such as caffeine to compensate for the lack of sleep.

Hey doc, I just wanted to let you know I was commenting on the post you made from the woman that emailed you saying that you saved her life. Right underneath my comment, it appeared as though you had commented back telling me about some great financial investment. I immediately knew it was a scam because there was an s on the end of the name, and yours doesn't have that. However, they were using your picture, and it did look like it could be yours. I'm afraid everyone won't be able to tell the difference ! I did report them but I wanted to let you know as well. Keep up the good work!

Interesting video. For me, personally, I've decided not to worry about sleep anymore. During the day, i can't nap anymore, i cant switch off, so i just need to make sure i dont stay up late anymore. If i do stay up, I make sure i put my feet up during the day for a few hours relaxation. I no longer care about catching up on sleep, just try and get at least a good 7 hours, and more if I'm lucky. Sleep stress for me was a real thing, but i feel better now that not napping or having bad sleep at times is ok.

Like anything else in life, if you stress about it, it will get harder for you. Sometimes you can't avoid the stress because the stress is natural. But stressing over sleep is definitely not natural.

Thank you Dr Karan for releasing all these podcast videos, very informative and interesting and always a great choice of guests☺ I don't really have the option to make time for naps at the moment but have followed your advice on sleeping patterns and routine before bed. Not fully there yet (guilty of using the PC a bit too close to bed time) but it has helped reduce my sleepiness. That and I would confirm that sleeping extra hours almost every day can be rooted in stress so it's good to address the root cause or find a way to counter the effect. Sorry for the long message, and thanks again!!

I never understood why in pre-school and/or Kindergarten there was "Nap time" but when you hit 1st grade and went through grade to highschool, they essentially called you lazy for napping during like Study Hour. Not to mention how people are more likely to get sleepy after they eat, so those last few classes you have after noon may not stick with you as much because you're tired. At least in America, we're worked to death. We literally are just cogs in the machine. And younger and younger generations are recognizing this from seeing their parents work their buts off for crumbs, and just start thinking, "What's the point in doing that or this?" That's why a surgence of flexible schedules and 4 days of work instead of 5 are becoming more prominent. Jobs should have an hour or two per day where everything's closed and it's "Nap Hour". If jobs are open 24 hours, then there are 1 - 3 or 2 - 4 "Nap Hours" per day. And we should get paid for it if we're forced to go home and sleep because I've always believed that ALL my time involved with work should be paid, so that means from the moment I'm on the road to the moment I'm home, I should be getting paid for that. We all know that majority of the companies and corporations we all work for CAN 100% afford it. Majority of them can even pay people double what they're actually making. But we all know how GREEDY capitalism is. I can bet you $1,000 that EVERY single person can live off $100k per year comfortably. You could actually live off 50k per year comfortably as well, but 100k is a comfortable amount. Now imagine all these million and billion dollar companies if they just put more money into the people's hands or into the economy and planet. We'd have evolved civilizations long ago. Nobody needs to work so many hours per day. Most of us can live without some of the conveniences we have in left for a day or two. It's not that hard to be responsible and budget and plan, despite what people say or think. Most of us are just lazy. That's why everything's getting more convenient. I'm a lazy person, but I can at least take accountability, but I also know how to be responsible, budget, and plan things. Either way, at least start with mandatory Nap hours with schools, then move it up to companies and jobs.

2:20 The affect of chronic trauma during childhood and critical developmental periods on adolescent and adult sleep? I have a speculation that hallucinations and delusions are the result of the affected individual's brain trying to force the glymphatic system to dump all that rubbish. Maybe there's an issue with the dopaminergic areas that screws up the brain's ability to co-ordinate the sleep functions, resulting in insomnia - a common precursor to psychosis. Psychosis might be someone dreaming while still appearing to be awake. An incidental discovery I made when I got new orange tinted lenses for driving glasses - eyes don't have to hurt, things stop having that barely perceptible glow, colours are more saturated, mood instantly improves, and sleep is easier. I previously found sleeping prone, heads down, feet up, also improved my sleep.

No wonder I always get good grades even though I'm always napping in classes. That bothered my teachers a lot, but they gave up trying to keep me awake, and I get good grades anyway. Hahaha. My whole family are nappers, so I wonder if there's some gene that controls your preferred sleep times. My husband prefers to sleep late since his brain is more active at night, but I prefer to sleep early and my brain is more active in the morning.

Im not sold on her point about oversleeping. As far as i know, its terrible for your health in the long run. Aka heart issues and brain issues but perhaps the data i had wasnt that great. What urks me is that the people in the experiment she mentioned didnt oversleep the whole time. Only during the first few days. If they have nothing else to do besides sleep then why would they choose to sleep less after those first few days? It doesnt make any sense. *but they werent sleepy anymore and listened to their body* Ok then how can we call that over sleeping? They could sleeping longer than usual in the first few days because they needed more sleep to catch up with sleep they were lacking and then they went back to normal. This really grinds my gears because i want to take her word for it as she is an authority figure on the topic but her claim just sucks
