How long does bleach poisoning take to affect?

I was Poisoned at about 12 A.M. one night by showering in a shower that was being cleaned with bleach and I felt the affects as soon as I woke up the next morning. I woke with a sore throat and I felt very weak. The sore throat stopped and the nausea started. Then at about 7p.m. that afternoon the diarrhea and vomiting started. I felt like I WAS GOING TO DIE. I would have went to the doctor but I was in mainland China and they like to quarantine U.S. citizens for any little reason because of the swine flu scare. We should be treating there citizens the same way in our country so that they see how it feels to fear getting medical treatment. It lasted for about 3-4 days. It really can be confused as food poisoning so think back really well about all the places you've been and eaten. Good Luck, you will survive unless you swallowed it then go call 911 ASAP!

How can seawater dehydrate you?

Seawater contains sodium or salt. The amount of salt in sea water is several times higher than what your body needs. Your body absorbs the salt into your bloodstream which raises the salt concentration level or serum level of your blood. This triggers 3 things to happen. First, it causes the water in other cells in your tissue to rush to the blood stream to try to dilute the salt so now your tissue (muscles, skin, etc) is now dehydrated. The salt level also triggers your brain to tell you to feel thirsty so you will drink more fluid to help dilute the salt. If you are stranded at sea, you will become even more thirsty than you were before! Third, the brain tells the kidneys not to produce as much urine so you don't pee out the water and the fluid that is now rushing to your bloodstream to try to dilute the salt. But because the salt content is so high in seawater, it is almost impossible for the body to dilute that amount of salt so you just keep loosing fluid from your tissue and your kidney stop making pee altogether. Your brain is very sensitive to salt and even the smallest amount of difference of your salt level in your blood causes the brain to start doing very strange things so you also go crazy. Now, your tissue is dehydrated, your kidneys are not working so toxins are building up in your body and you are still very, very thirsty!

Can you use rubbing alcohol on a cold sore?

Back in the day, people thought that if an antiseptic didn't burn, it wouldn't work. Just because it burns doesn't mean it will do any good! Cold sores are caused by a virus so you won't kill the virus without killing the cells that it is invading. What the alcohol will do to the sore is to irritate the sore, dry it out on the surface and make it crack open even worse. If you want pain, rub some tobasco sauce on it...that won't cure it either but at least it isn't toxic.

Why does alcohol smell?

Exactly what your nose responds to as a scent I cannot say, but the reason that some things seem to smell more or further away has much to do with how much of the substance is in the air that you are breathing. Everything has a vapor pressure at any temperature above absolute zero. Vapor pressure is a way of stating how quicklya substance will become a vapor and thereby become airborne. Alcohol has a relatively high vapor pressure at any "normal" temperature and therefore is relatively quickly added to the air when a container of it is opened. Its molecules also are movingrelativelyfast (which is what causes a higher vapor pressure in the first place)and that means that its smell will travel quickly throughout an area.
