SCUBA
Scuba diving is a sport in which you can lose yourself to the beauty of the underwater world and escape gravity for a short time. You can wander among kelp forests or swim with sleek noble sharks. You can find a fortune in Spanish ducats or encounter a rare squid. Some may say that diving is "an extreme sport" and "it's just for the wild hooligans." Scuba diving is a safe and enjoyable hobby, which most people can experience if they have undergone proper training. Although there are many risks, most can be avoided when using proper technique and scuba diving ethics. Going below the water is vastly different from being above the water. While underwater there are forces and laws that dictate how your body will respond to being under so much pressure. The first rule regarding the pressure water puts on the air spaces in your body is Boyles Law. It says that as the pressure increases on a given mass of gas the volume will decrease. This rule explains the popping sensation you feel when you go up in an airplane and the squeeze you feel as you go under water. Another law is Dalton's law of Partial Pressure. It says that pressure of mixed gasses is equal to the pressure exerted by the in
Dehydration can occur more quickly while underwater, because you breathe very dry air from the scuba tank and your body makes more urine, as a result of the pressure. As you progress through the class half of the time is spent in a swimming pool where students can master the necessary skills for diving without having the pressure and risk of being in the open water. These basic skills along with several others, are taught by a certified and experienced instructor trained to teach the skills effectively and to determine whether you are competent to scuba dive. Although stress is one of the diver's worst enemies it does not have to cause accidents. Though the squeeze causes pain, it does not cause death like stress. The most common problem for most divers is a pain in their ear, sinuses, or teeth. There are several major certification courses and most are recognized worldwide. Panic attacks may not apply to everyone, but decompression sickness can affect anyone. Stress is one of the biggest causes of death while scuba diving. Dehydration, as already mentioned, and overexertion, may also cause DCS. First you learn how to use and wear scuba equipment. Most inexperienced divers do not recognize the symptoms of stress before they culminate into full-blown stress or a panic attack. Some of the signs of DCS (decompression sickness) are: a blotchy skin rash, favoring an arm or a leg, lung collapse, staggering, and unconsciousness. If a mixture of gas contains 5% carbon dioxide then it would account for 5% of the total pressure of the gas.
