YSK - for all the things that can make your life easier!

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)

Rule 1- All posts must begin with YSK.

All posts must begin with YSK. If you're a Mastodon user, then include YSK after @youshouldknow. This is a community to share tips and tricks that will help you improve your life.

Rule 2- Your post body text must include the reason "Why" YSK:

**In your post's text body, you must include the reason "Why" YSK: It’s helpful for readability, and informs readers about the importance of the content. **

Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.

Rule 4- No self promotion or upvote-farming of any kind.

That's it.

Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.

Rule 6- Regarding non-YSK posts.

Provided it is about the community itself, you may post non-YSK posts using the [META] tag on your post title.

Rule 7- You can't harass or disturb other members.

If you harass or discriminate against any individual member, you will be removed.

If you are a member, sympathizer or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.

Rule 8- All comments should try to stay relevant to their parent content.

Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.

Rule 10- The majority of bots aren't allowed to participate here.

YSK hands, feet and the upper part of your face are the most effective vectors of heat relief, while draping a cold towel around your neck can actually stop you from cooling down. (www.scientificamerican.com)

Why YSK: "Our bodies have a kind of emergency temperature relief valve. That valve is a special type of blood vessel: they’re called arteriovenous anastomoses. Most arteries and veins connect through a bed of very thin capillaries that bring nutrients and oxygen to cells. AVAs, though, are different. They are direct junctions of arteries and veins, so blood flows through them pretty quickly. And the real key to their heat relief function is they are concentrated in just a few places in the body. We found that in the palm of the hand, the soles of the feet, and the upper part of the face, which are called non hairy skin, there are special blood vessels, and those blood vessels can shunt the blood from the arteries to the veins directly, bypassing the capillaries."

On the wet towel on neck trick: "The reason is the brain has a thermostat that it uses to trigger the body’s natural cooling mechanisms, like sweating or passing blood through those AVAs. That brain region is located near the back of the neck. It uses neck skin temperature, and blood temps in major vessels there, to measure how hot you are. So your cold towel is going to fool the brain’s thermostat into thinking that your body has cooled down. It’s going to shut down all your other natural cooling methods. And you’ll stay uncomfortably and sometimes dangerously hot."

Im fairly healthy, but have hyperhidrosis and sweat like crazy in the first place. Like way more sweat than a body needs to cool off. I recently got a cooling towel and started putting around my neck. It's a life changer. If it's tricking my brain into not sweating then imma risk it
