Wear as little as you can. Even a round brought short sleeve would cover about 40% of your body. You'd better dress in light color to reflect the sunshine.
If possible, you can use water (the cooler, the better) to sprinkle the body to help strengthen your sweat function. When it is warm, I usually take running along the river Kenaz. When I feel hot, I would stop to wet my body into the river(but I don't think it wise to drink the water in the river). In the process of the marathon, some people may offer you some water, and if you can't drink out for one time, just try to satisfy your need and topple over the rest onto your body. (According to the Dr Clark, who works in the national medical institute in London, when people are running, the temperature of all the parts of the body tends to increase, and the thigh increases the most. Doing in this way, a better capacity for running will come to you, but for some runners, some bubbles would sparkle on the wet feet.
Spend time as little as you can in warming up. As what we have discussed earlier, all the activities you have conducted is useless. And it benefits you nothing but to increase your body heat. (Incidentally, the Western Kentucky University conducts a study, and, on the basis of this research, it proves that the ability to resist heat and recover after heated won't be weakened by the long hair, even if the athletes have a long hair to the shoulder.
The above tips have been written down into a pamphlet, and it has been sent to the athletes, who are going to join the marathon race. In an article named the medical facts you should know, it says, the problems about hot: these problems usually happen under the hot, humid, or hot and humid climate which make people easily lack water and salt, even have the body temperature increase to a dangerous level. In fact, we can take some measures to prevent these problems, for instance, insist training under warm climate for a week, on the first day of the game, don't have breakfast until ten o'clock in the morning, and the athletes can put more salt into their breakfast, or have one or two cup of very salty broth. (Take salt before the race would cause nausea). During the process of the race, every time when you run by a supply beverage, you should drink two or three ounces of water before you feel thirsty.
Not everyone is troubled by heat problems. Seeming to have some unique ability to protect themselves form heat, even when it is midsummer, some people still can run very well, however, for the other people, the running speed would reduce dramatically as long as it is hot.
Generally, one's bulk decides his or her ability to resist heat. When it is hot, if a person is very heavy, he will be less competitive. As we know, heavier he is, less skin surface area for him to disperse heat. What's worse, hot would be stooped inside by Fat. But people show different ability of running in hot weather, and we often find it incredible, because the differences are too obvious; Each one is unique, this may be the reason for it.
Humidity itself is not a problem. As a matter of fact, only when it is hot, and humidity makes it more difficult for the runners to run, humidity can be thought as a problem. With the humidity one hundred percent and without wind, it is difficult to make the sweat evaporate. Under this condition, your body may not stand the heat. You can apply a wet bubble thermometer to judge to what degree the problems aroused by humidity have reached. If the temperature is more than seventy degrees, then the game will be difficult for the runner to continue. If the temperature is more than eighty degrees, then whatever sports you are engaged in, this has nearly reached the ceiling.
