Licking the goggles is the best way to help professional swimmers because their tongues are more flexible and because they have too much training. Under the non-human training intensity and use intensity of professional athletes, a new pair of swimming goggles was quickly used and no longer anti-fog.
So they lick the goggles to remove the fog on the lenses quickly. It’s not that they can’t afford to buy new anti-fog glasses, but people will develop the habit of using them when using items. During the competition, most players choose the swimming goggles that they usually wear during training. This principle is the same as some football players wear old shoes to play, long-distance runners will not wear new shoes to run a marathon.
How hard is the training intensity of professional athletes to make the anti-fog effect of swimming goggles look so unusable?
A swimmer said that his daily training volume is between 15,000 meters and 20,000 meters. Phelps once described his training volume as follows: "I now train 80,000 meters to 100,000 meters per week. Training for 7 days." "When I was fourteen or five years old, I trained more every week, swimming 50,000 to 60,000 meters every day, almost all year round."
In contrast, it is not easy for ordinary people to swim 1,500 meters at a time. Under this kind of training intensity and use intensity, the anti-fogging of swimming goggles has naturally become a "fast-moving consumer". Imagine that when you have to repeat something several times a day, of course, you are used to completing it in the easiest and fastest way. It is more convenient to just lick it off several times than to take the anti-fogging agent and apply it slowly.
Some professional swimmers also joked that this is a must-have activity before training every day. If you don't lick the swimming goggles, you are embarrassed to say that you are a professional swimmer;
Why does swimming goggles fog up?
Generally, the fogging of swimming goggles is the endoscope, that is, the side facing inward and directly facing the eyes. Because the inside of the lens is close to the skin, the temperature is high, and there is a temperature difference between the inside and outside of the lens, and the sweat of the skin evaporates during exercise, forming a lot of small water droplets and condensation.
Generally, the endoscopes of swimming goggles have anti-fog treatment, but they have the same life span as rainproof coatings such as jackets. As the number of times of use increases, the effect of the anti-fog coating will decrease quickly. This will hinder the swimmer's line of sight. Imagine that there is a vast expanse of whiteness in front of you, even if it does not directly interfere with your movements, it will also affect your psychology.
Why can licking swimming goggles prevent fogging?
The essence of the fogging of swimming goggles is that a small drop of water on the mirror surface causes light scattering, and there is no way to prevent the moisture from condensing and forming fog, so what we can do is to turn these small water droplets into a uniform water film. Will block the line of sight.
Licking the swimming goggles gives the endoscope a thin liquid film, so water vapor cannot be attached in the form of small water droplets. The tongue is softer, and it can also avoid scratching the goggles. Individual swimmers also lick the outside mirror of the swimming goggles. This may just be a habit, because the outside mirror does not fog up. Under normal circumstances, the saliva application method can keep the lens transparent for about half an hour. In addition to licking with saliva, many people also use shampoo, hand sanitizer or even detergent instead of anti-fogging agents. But these are emergency substitutes. In case of water in the swimming goggles and contact with the eyeballs, it is easy to cause discomfort. Whale goggles is a good choice for you.
