Drink cold water after strenuous exercise, especially for temporary pleasure. Drinking a lot of cold water can cause stomach cramps, stomach cramps, and severe syncope, which needs to be sent to hospital for rescue.
Take a short rest after exercise, and then drink warm water, not too much at a time. It is best to drink light salt water, which can not only quench thirst, but also supplement the salt lost in the body due to perspiration.
Scientifically speaking, it is better to drink isotonic drinks, that is, the ion concentration in drinks is similar to that in human cell fluids, because it will not cause cell expansion or dehydration. It's safer and healthier. What is an isotonic solution? For example, red blood cells contain some electrolytes. There is a certain pressure between adjacent blood vessels and some salts and protein, so that red blood cells can walk freely in the body. This is an isotonic phenomenon: the osmotic pressure inside and outside is equal, and the amount of water molecules inside and outside is the same, so red blood cells will not become "balloons" or "shrink". When we make water in strict proportion, our products become isotonic solutions suitable for absorption and walking in the body. When you drink it into your body, it will swim freely between the intestine and blood vessels and be easily absorbed by your body. If it is not isotonic or hypotonic, water will run into red blood cells and dilute the concentration inside, and red blood cells will be destroyed. If it is hypertonic (that is, the concentration outside is too high), the water molecules in the red blood cells will run outside and dilute the concentration outside. Red blood cells. For athletes and people engaged in fitness, the most sensible way to use sports drinks is: 1) frequent intermittent drinking all day, before, during and after exercise; 2) Choose your favorite drink. Cold drinks are usually more delicious and conducive to the recovery of physical strength; 3) Choose a drink that meets your own needs. Remember that if there is no shortage of sugar in your body, adding too much sugar to the drink will not help; 4) Ensure maximum intake of drinks before exercise, but don't cause stomach discomfort. During exercise, drink150-250ml every15-20min with the emptying of drinks in the stomach; 5) Start using sports drinks earlier during exercise, and don't wait until you are thirsty, because you are dehydrated by this time; 6) Make up for all the fluid lost during your exercise after exercise. The degree of hydration can be judged by the color of urine, and the urine must be light; 7) If you want to celebrate the victory after the game, you must make sure that you have fully replenished water before drinking; 8) Without a reasonable diet, sports drinks can't make you successful. Effective training and a healthy diet and lifestyle will make the sports drinks you use play the greatest role.
