I love a podcast guest who answers the majority of the questions with 'it depends' or 'we don’t know yet'. This is someone I find trustworthy because they aren't trying to sell me their 'method' of fixing the problem

[Brunneria]

After years of bad sleep, my new apple watch told me my oxygen levels were going far too low when asleep. Doc sent me for sleep test. Diagnosis of severe obstructive sleep apnoea. Given a CPAP machine. It has changed my life. Sleeping well. Depression gone. Appetite reduced. Able to lose weight! Better focus. Better memory. Less I would encourage anyone with bad sleep to not give up until they have an answer. Don’t lose 30 years to sleep deprivation, like I did.

[bigbooza]

Who else is watching because they can't sleep? 😅

[mikeburrows]

I am 63, my insomnia started when I was 18 and has persisted ever since. I have tried many things CBT, antidepressants, exercise and night time hygiene. It was worse when I was young when I averaged 4/6 hours but often sleep 0/3 hours. For me anxiety ocd was the cause although it took me years to realise this and I often avoided situations that caused this. With medication I held down a management position but at times it was tough. My sympathy goes out to fellow insomniac's.

[girlcosmiccosmicgirl]

Every single week your podcasts are so relevant to my life. It's unbelievable! Thank you DOAC!

[Abbiejangel]

Thank god I got a notification for this one, I haven’t had a good night sleep in 7 years. I can go 3 days with no sleep at all it’s pure torture.

[fakiriayoub]

Psychedelics are just an exceptional mental health breakthrough. It's quite fascinating how effective they are against depression and anxiety. Saved my life.

[chantellebarrowmusic]

Brilliant watch,
I was diagnosed with chronic insomnia after 30 years of suffering.
I don’t produce as much melatonin as others

I now have medical cannabis high strength of Indica & it’s saved my life & got me off sleepers.

Before going down this route.
High strength Magnesium
5htp/melatonin tablets are beneficial.

Other things you can do is eat cherries or banana before bed as these are high melatonin content.

Also raising your temp by a few degrees before sleep ie hot shower hot drink, when temp drops it promotes the falling asleep stage..

Also one leg out of the bed to regulate temp.

I became a sleep expert by default.

Love that you’re doing a raffle. Great idea.! X

[dancingverona]

Since suffering burn out and it taking 3 years plus to recover I take sleep very seriously. So interested in this particular podcast...❤❤❤❤

[MphoPersonalVideoDiary]

The amount of times that he has said he isn't sure or doesn't know the answer to some questions, makes me respect him even more because it shows that he has integrity and isn't in it for the fame or being popular but he is in it to actually help his fellow humans. What an absolute gem 💎💎💎

[bhatiamallika]

Completely agreed with your point on sleep identity. I told this story to myself all my life that I am a night owl and a bad sleeper. Cut to 2024, I get myself a whoop to sort my struggles with sleep and help build better habits. It helped me identity what I was doing wrong, eating late at night, not winding down. 6 months in I am yawning and in bed by 10.30 pm (this was unimaginable for me earlier) and I have 6 months average sleep performance of 98%. I never slept badly, I just told myself that I did. I was never a night own, it was my lifestyle that made me think that way.

[GEMMABurns-pmoh]

I have suffered with poor sleep for decades, I’ve put it down to depression and anxiety and now peri menopause. I have a crap immune system, have developed type 2 diabetes, and we have a strong family history of Alzheimer’s in my family including my Dad. So far my Gp has only given me either sleeping pills or most recently for the last 4 years I’ve been taking mirtazapine which sometimes helps me get to sleep but none of them help keep me asleep. Most nights I fall asleep around 10pm and I’m awake by 12-1am and I’m wide awake! I’m exhausted and life feels really hard. I’m now going to make an appointment with my Gp and fight to get more help!! Thank you for having this guest on!!

[marials]

I loved the interview!!! He speaks very clearly yet with a very scientific approach, avoiding this “dogmas” and this categorical way of speaking that many other gurus in other fields like to use.

[elevatebusinessleaders]

Thank you for this episode. I have learnt a lot since I have kids who are super creative at night but sleepy during the day. I have been very curious about sleep. I have been one of those people, who love to take an afternoon nap to be effective at work. To be at my best, I need a minimum of 6 hours.

[GenRN]

One time I woke up outside after sleep walking. It was summer and blazing hot outside. I was a teenager and way overtired and physically exhausted. I had walked by my grandmother who scolded me for walking on her freshly mopped floor and completely ignored her. She had no idea I was asleep.

[simonw]

Great timing! Recently watched your interview with Matthew Walker, and have just read his book. As a stroke survivor, please keep the brain health interviews coming.

[existnow.]

I've just been awake for 31 hours and 27 before that with 4 hours sleep between. I'm 42. Had this issue since I was a kid. Yet NO psyche or doctor will give a formal diagnosis. I feel like a crazy person half the time not awake not asleep. And then all the misdiagnosis.. and denial of proper medication to help. I wanna cry thinking about it.

[dpnsster]

Thanks for actually getting an expert and not a journalist, paperback author, or somebody else with bias spruiking their own promotion.

[peaceemezue]

One thing this podcast has done for me is to think differently and look after my health adequately. This is the first podcast I have ever listened to and watched. Steven your podcast is very educational and informative. God bless you for helping us take care of ourselves. All these guys you bring at the minute I can’t afford to go to their clinics. But your podcast has made it possible for me to meet them via YouTube . Thank you
