Donating blood is a great way to help others and it’s easy to do if you’re relatively healthy. Of course, some people aren’t able to donate blood due to medical conditions or because they’re taking prescription medications. But even basic over-the-counter medicine can stop you from donating parts of your blood, like you can’t donate platelets if you’ve recently taken Aspirin. Because even though you might have just taken it for a headache aspirin also effects the rest of your body, including your platelets. When you get a cut, it’s your platelets, also called thrombocytes, that are mostly responsible for stopping any active bleeding along with other proteins They clump up and bind together Making a scab for your open wound when someone has a low platelet count that puts them at risk of severe bleeding Even for a less serious injury, that’s where donations come in unfortunately you’ll probably be turned away from donating if you’ve taken aspirin Too recently because it stops your platelets from working normally aspirin is a complicated molecule made of carbon oxygen and hydrogen It’s used to relieve pain and for patients at risk for recurring strokes Or heart attacks people have been using it since the 1890s, but it wasn’t until the 1970s that scientists actually understood How it works the drug blocks an enzyme called cox-1 that reduces the production of prostaglandins Hormone like compounds that normally cause inflammation and pain blocking those compounds is what helps your headache But the aspirin also inhibits the protein thromboxane thromboxane Helps create blood clots and scabs by constricting your blood vessels and recruiting platelets to clump together So if you take aspirin which stops thromboxane that prevents blockages from forming in your blood vessels and keeps your blood flow and free That’s why it’s so helpful in preventing heart attacks which are caused by blood clots and so harmful for hospital patients owner platelets are often used for cancer patients or for Complications in surgery so hospitals need to be completely sure that they’ll actually Work and will prevent excessive bleeding, and if your platelets aren’t clumping together like normal You can see why donating them to someone in need might be a problem if you’re interested in donating platelets Most donor banks suggest waiting about 48 hours after taking aspirin to let the drugs effects wear off So that your platelets can gain back their regular clotting cells, but if you’re scheduled to donate whole blood everything Not just the platelets, and you have a headache No worries whole blood Transfusions are often used in more general cases where the clotting property of blood isn’t necessarily the main thing They need so if your platelets don’t work normally It’s not as much of a problem for such a simple and easily available Medicine aspirin does a lot more to your body than you might think but as long as you plan ahead You can still go forth donate and help those in need I have an exciting announcement, okay? Here’s the situation the scishow team and I were talking about a problem that many of us share People will ask us what we want for Christmas And we won’t know what to say because like stuff and things seem so last century, right But then I was thinking you know there are some things that I would like to get or some things that I’ve gotten for myself that people have given to me that I really love because I love the world I love the universe or the existence of life that kind of thing stuff that is emblematic of my appreciation or it inspires me or it lets me learn things or do experiments on myself so we put together a collection of artifacts from this universe these scishow finds are curated by Me for the most part there are things that I know that I would love to get in my stocking It’s a very small list just a few things varying price points are probably gonna add some new finds as we find them throughout the next year and those new ones will replace the Old ones so all these products will be around only for a limited time on scishow finds calm you probably have friends or family who?
