Heatstroke is a serious problem and the heatwaves that cause it, claim more lives on average than any other weather event in USA. While generally thought to affect the elderly and the very young, it can affect people of all ages, not just because of the heat in the environment (classic heatstroke) but also because of activity (exertional heatstroke). The problems caused by heatstroke sometimes happen but don't appear clinically, like GI ischemia.

Bitcoin is a decentralized cryptocurrency that's used in peer to peer transactions. This happened in 2011 when individual people could still mine coins, but now, miners are usually pools or in large facilities in places that have cheap electricity and cool climate to save on computer cooling costs.

    Randomly includes one of the most accurate and concise summaries of Bitcoin.

    "People joked that OP had brain damage before that" caught me so off guard
  • @glenmartin2437
    Thank you. During the 1960's, high school and college coaches were telling athletes not to drink water after intensive exercise in the heat!! Crazy.

    Happy to see another episode of Heme Review! The originals are always amazing but these are so in-depth and rapid-fire.

    Hi Chybbyemy, I first saw your “How I lost 60 pounds in 16 weeks” video back in 2016. Over the years, I’ve been randomly checking back until this spring break during COVID I stumbled upon your “Life” playlist and it really changed how I look at things. Back in grades 8, 9 and 10, I was a loser who only played Video games and napped after school. I was that kid who never did any work and well, got what I deserved. I was averaging less than 60%. What was more humiliating for my parents was that well, I’m ASIAN. I bet you know the stereotypes for Asians being smart and good at math. Well, I'm busting that myth right here for anyone else who reads this. IT'S NOT TRUE. No one can get 100% on a test just because they are a certain race or ethnicity. We are all humans after all. Anyways, grade 11 comes around. I got my shi* together and I guess did an ok job in grade 11 averaging in the high 80s, low 90s. I’m turning grade 12 in September. I hope I can better myself again. Your medical videos sparked my interest in medicine. your fat loss videos inspired me to get off my butt and exercise a whole lot more. Most importantly, your life videos made me realized what I needed to do. I hope I can follow your paths regardless of the hardships. Because discipline is the key to success. Have a nice day or night whoever is reading this!

    I had heat stroke one time when I was five or six years old, (shout out to my neglectful parents lol) and I still remember it because it was absolutely awful. Please be safe if you’re anywhere it could get hot, you absolutely do not want heat stroke it’s so scary
  • I can relate. Heat sensitivity runs in my family and I have it too, so by default I'm more prone to get heatstroke even in slightly-cooler weather. I live in Arizona.... It's uhhh fun trying to make sure i don't get heatsick
  • @SpudBySea
    Another great video- especially appreciate the direct comments on bad coaching believing more sweat is better. It might be due to editing, but the asthma study commentary at 9:40 doesn't fit the narrative well. It seems introduced to suggest that since a totally different topic on life expectancy has contradictory evidence that no beliefs on life expectancy impact are certain. It doesn't really jive with the thorough and data-driven tone of HR.
  • I loved this so much!! I've had multiple sclerosis for over 10 years & my symptoms get worse when I get hot but I never understood(or could get an answer why) until I saw your explanation about interferons in this episode!!
  • @moneyluser5711
    This high bandwidth medical knowledge infusion is unparalleled. I hope you have done or plan to do some cell biology and cell biochemistry episodes.
  • @martinvasut4319
    My all-time favourite show. Makes learning a joyful process. Thank you!
  • @AB-wq2vy
    As final year paramedic/nurse student that is concidering to become a doctor, I thank you for these videos Bernard. They really do motivate me to study further because you explain these complex subjects so well that it is easier to understand.

    “Walk it off, son. No one likes a pansy.” “Ok, coach.”
  • @atokasnips7618
    I had a heatstroke from working, stacking wood for winter, and at the SAME TIME(before the lock down in my nation happened), got covid. I thought for a whole two weeks I thought I was still suffering from the heatstroke since I couldn't breath well.....NOPE it be the covid and this happened near winter time. In short: Got a heat stroke and covid on a cold day somehow
  • @anjelpatel36
    Man, every Heme Review makes me so conscious of my current stats. I just drank some water and turned on the fan.
  • @ersetzbar.
    I always assumed the human body is well researched, but having it explained into such detail for an example is still mind blowing. Finding out the body functions that are connected from this huge complicated chemical system, filtering those unrelated and sorting for cause and effect must be so very difficult.
  • Hey doc thanks for the amazing video as always! You're doing a great job not inly educating/entertaining people who are interested in popular science (chybbyemu), but also helping international medical students to practice specific english vocabulary!! As a one of those i was so grateful that you provided your first channel videos with ENG SUB, but you speak SO well that autogenerated subs on this channel are higly coherent so i get every single professional (or not) word very clearly (now that i learned exactly what does -emia and stuff mean from chubbyemu). Plus it's SO convenient that you always mention Litres and Celsius, it makes me happy, no one on YT cares that much about international viewers. THANK YOU doc from the eastern europe country everyone constantly makes fun of :))))
  • I have Hashimotos, which in the literature states one consequence is reduced regulation of electrolyte -water balance in body. Since i developed it 8 years ago, i sweat profusely, just froma warm day or high humidity or ordinary housework. Its embarassing socially, and i frequently feel nauseous, bad headaches and loss of motor skills- increased clumsiness. I have tried to manage this as best i can, but have had so little recognition, advice or support from Australian doctors to manage it. It is literally disabling, and i can only endure part time work, as my health goes into a downward spiral otherwise.

    I love you. I have severe hypochondria, and heat stroke is my biggest fear due to my high blood pressure, and now I know exactly how to avoid it. Thank you.
