If you plan on living a life of any length underwater, one of the most important cold-water survival tips that you should follow is to get wet. Getting wet can help ward off many forms of aquatic microorganisms and diseases. Additionally, getting soaked in the rain or snow will also provide much needed hydroelectricity for your body.
In the event that you do not have access to water of any kind, be sure to carry plenty of food and clean water. It is also a good idea to carry a signaling device in case you come across anything that may be threatening while swimming. Many animals like snakes have a keen sense of smell, so if you are swimming in the middle of a swamp, it is a good idea to wear a flotation device. Keep one wrapped around your wrist, and another attached to a piece of heavy rope nearby. As an added measure, always make sure that the signaling device stays in sight at all times.
One of the most overlooked cold-water survival tips is to avoid being eaten by fish. Although this may seem like a difficult task, fish have poor eyesight and will most likely not notice you unless you are moving very quickly and their eyes are closed. However, there are certain types of fish that are more likely to attack you. Examples of these fish include larger predatory fish such as sharks and rays, as well as certain flat-finned species.
The first thing that you need to do if you come upon a hostile fish is to flip on your stomach. This is necessary because when you lie prone in the water, you are more likely to be eaten by the fish. For this reason, it is important to keep your head up as much as possible. To accomplish this, simply raise your head off the water by at least ten feet, and hold on to something to keep yourself upright. This will allow you to see the surroundings more clearly and to react faster if attacked.
Another of the cold-water survival tips is to stay as still as possible. If you are attacked by a shark or a ray, being disoriented and confused is an added advantage for you. Although being quiet may seem like a difficult task, sharks and rays can hear a heartbeat and will often make their move during this time. Therefore, remaining still will help to keep from drawing their attention.
Finally, one of the best cold-water survival tips is to stay alert. Fish can become extremely alert to human scent. Therefore, keeping your body odor free will be beneficial because the fish will be unable to tell whether or not you are swimming near them. It is also important to try and keep your clothing dry. If you get stuck in a storm, your body will naturally attempt to expel any moisture that is present, which can make you even more susceptible to attack.
One of the most common cold-water survival tips is to avoid large groups of people when possible. When you are alone, there is a better chance of you making it far if you are attacked by a shark or a ray. Therefore, if you have a group of family and friends staying at the same time as you are, it is very important to divide up the human population. If you are attacked by a shark or a ray, it is much better for you if everyone stays together rather than trying to run off together. The more people you have around, the more chance you have of getting out alive.
It should also be mentioned that sharks do not attack just anyone. Therefore, you should take special care when swimming near any large schools of fish. If a shark sees that you are swimming nearby, then they will not hesitate to attack. If you follow all of the cold-water survival tips outlined here, you have a good chance of surviving the shark attack.
