World News
A community for discussing events around the World
Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Googled it, hot tubs temporarily lower blood pressure.

Dr. Adolph Hutter.
I'm guessing that man has an immaculate signature that makes sure it's super clear that there are two t's and no l's in his last name.
Also, shaves everyday.
Just above his lip only. Full beard otherwise. "It's literally the opposite of the hitler stash!"
Yeah, better be sure.
Or his handwriting is so bad that his signature is a completely indecipherable squiggle. Seeing as he's a doctor that seems more likely.
So actually comprehending this, if that is what I'm doing, the heat is causing your body to do what it does when your blood pressure is spiking, but since you are in a body of water, the weight of the water is changing the atmospheric pressure on the the body, and nets to lower blood pressure.
Heat is making the heart pump harder, and the blood move faster, but the atmospheric pressure is dilating the blood cells, resulting in net lower PB.
Kinda sounds like "wreaking havoc on the circulatory system". Same as rigorous exercise weeks havoc on the circulatory system.
Overdo stress on the circulatory system, get heart attack or stroke.
Pressure would play little role here, generally it would increas peripheral resistance as well as pressure inside the chest cavity, prompting the heart to work harder. However I doubt at a regular water immersion in a hot tub causes a noticeable effect.
Then heat causes your blood vessels to dilate in an attempt to dump the heat outside, because you are in a hottub this will end up warming your core, which will also dilate more blood vessels inside as well as raising your resting heart rate.
The net effect is slightly faster heart rate (still usually under 100, so not even in light excercise teritory yet, more like walking teritory) with a lower blood pressure.
None of this is close to wrecking havoc, yet the initial drop from getting in quickly can be fast enough, that with a high enough vagal tone (i.e perfect storm of other situations - tired, dehydrated, intoxicated, chronically tired or w/e) you could temporarily pass out. Analogous to someone passing out from getting up too quickly.

But that guy sounded so confident, he even added a superlative
Sounds like it's not as simple as I thought it was.
Pretty sure I'm still pretty accurate on the "wreaks havoc" part.
You are not
Okay hot tub salesman.
Indeed, hot baths are so harmful to your health, which is one of the reasons why the Japanese have one of the shortest lifespans on the planet - it's because of those daily hot baths and onsen that they partake in.
What a dipshit argument.
Ya, if you run 5 miles a day every day, you're gonna be in great shape.
If you snort mountains of coke and eat cake without any exercise for 20 years and then force yourself to run for 5 miles, you're going to blow your heart out.
Recent studies say for most people, a half hour in the hot tub is the equivelent of a half hour run. It is intense on the circulatory system.
If you are saying Mathew Perry had the diet and physical activity level, and hence the circulatory system of a 54 year old Japanese man, then youvare a dipshit.
It is the equivalent of a half hour walk at best, heart rates dont generally break 100’s in a hottub, a slow jog will be in the 120-140 range.
If I recall my terms right it’s vasogenic shock. Essentially pipes without enough fluid and thus not enough pressure make the pump go wonky… so, yea, havoc wreaked. I’d say you’re accurate there.
Vasogenic shock is caused generally by severe disregulation in the body - anaphylaxis, sepsis, lactic acidosis.
What could have occured is a vasovagal syncope, where a sudden transient drop in blood pressure causes someone to lose consciousness temporarily. In this case, being tired, sleepy and getting quickly into a hottub, or sitting in it for a bit and then getting up suddenly could do the trick.
