Swimming is a great sport to help you own a good physique and tough health but to be safe, do not encounter dangerous incidents, must also pay attention to some preparation issues and during swimming.
1. Do not enter the water when you are tired or sweating
After working, if you sweat a lot, you should not jump into the water to swim right away because you are prone to sudden colds, even fainting, called “hit by water”. The reason is that the body could not respond to the sudden change of hot and cold temperatures. This is the main reason why swimmers also drown in shallow water.
Unlike those who drowned due to water-filled lungs, those who were “hit by water” had fainted first and then suffocated. Therefore, if you are sweating a lot, you should rest for a few minutes until exhausted, the person is dry and then go into the water.
2. Do not eat too full before swimming
Overeating before eating will make you feel sluggish, uncomfortable, drowsy body, abdominal pain and affect swimming performance. Because, to digest the amount of food you consume into the body, it will take about 45 minutes, at which time the blood will rush to the digestive organs to perform this function.
So, if you do not want to be influenced by many factors while swimming, you should not eat at least 45 minutes before swimming.
3. Warm up before going in the water
Before swimming, in order to prevent unwanted consequences such as cramps, muscle contractions that may cause an accident when swimming, you need to conduct warm-up exercises, stretching the muscles and joints in the body.
Experts recommend that you should warm up at least 10-15 minutes before you go down to the pool. In addition, it is also advisable to apply some exercises to exercise hands, feet, neck before swimming to warm the body, to prevent fatigue.
Do not abruptly swim down because the difference between pool water and body temperature will cause disadvantages for body temperature, heart health and general health.
