Do you know that athletes lick the goggles before entering the water?

The brand of whale goggles is authorized and customized. The famous swimmers in the Olympics, and even those enthusiasts who love swimming all year round, seem to have a strange little habit-like to pick up the goggles and lick before swimming. Why is this? Why do swimmers lick their goggles before the game? This situation of licking goggles is mostly caused by professional players, 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 in order to quickly remove the fog on the lenses. It’s not that they can’t afford new anti-fog glasses, but people will develop the habit of using them when using objects. When you adapt and get used to these glasses, you will inevitably feel uncomfortable when you change to a new pair, especially in important situations. During the competition, most players will 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.

The famous swimmer in the competition, after licking the left side of the swimming goggles, then licking the right side, and finally put it on. The above was before the 200m medley of the 2008 Beijing Olympic Games, Hungary's Laszlo Cech demonstrated the standard posture of licking the goggles. Obviously he licked (eh, swim) very well. He eventually won three silver medals in the men's 400m medley, 200m butterfly and 200m medley in Beijing. How hard is the training intensity of professional athletes to make the anti-fog effect of swimming goggles look so unbearable to reuse? Sun Yang previously stated that his daily training volume is between 15,000 meters and 20,000 meters, and swimming GOAT (the best in history) Phelps once described his training volume as follows: "I now train 8 per week. From 10,000 meters to 100,000 meters, I train 7 days a week." "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." Under the circumstances, 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 that enters the water, 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 a life span like 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 obstruct the swimmer's line of sight. Imagine that there is a vast expanse of whiteness in front of you, even if it will not directly interfere with your movements, it will also affect your psychology.

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.

What is the correct posture for licking swimming goggles? There are two most common types of application, dry type and rinse type. The former will wait for the endoscope to dry before launching. This is the best anti-fogging effect. Most professional players will choose to use this type, and they know it should be How long do you start licking before the game; the latter is to rinse with water immediately after licking, the effect will be slightly worse than the dry type, from the anti-fog effect, the difference is almost 8 points and 6 points. As for how to get saliva on the lenses, some athletes like the tongue kiss style, that is, the tongue is swirled in the glasses, carefully licking back and forth, licking in circles...There is also a blowing kiss style, just spit saliva in and lick, or spit it out. Then use your fingers to wipe evenly. There is no difference in the anti-fog effect. The anti-fogging effect can only be achieved by licking the dry endoscope of the swimming goggles before entering the water! If the swimming goggles have become wet with water, the effect of licking the goggles will be greatly reduced.

Another benefit of saliva is that as the human body secretes its own fluid, it will not have side effects on the human body. Compared to anti-fogging agents, saliva is more environmentally friendly and more convenient, so almost everyone who doesn't need money professional players will do this.
