Dog days are the hottest time of the year, but it's also the best time to play in the water – and who can resist being surrounded by cool water when you're sweating profusely after just a few steps?
Now it is the summer vacation, in order to understand the heat dissipation, many parents take their children on vacation to the wild mountain streams, ponds, small rivers to play in the water, for them, these waters are completely the gift of nature, not only do not need to spend money, but also cooler than the swimming water park in the city.

Stop! Stop this dangerous idea and go to unexplored waters is not so simple!
In addition to small fish and shrimp, there may be a variety of bacteria, viruses and parasites in the water, such as Escherichia coli, salmonella, norovirus, hepatitis E virus, schistosomiasis, leeches, etc.
It is inevitable to drink a sips or two of water when swimming in the river, in case you drink germs and parasites into the stomach, it will cause corresponding diseases, even if you do not swim, just play in the river, viruses and parasites may invade through small wounds on the skin.
Ectoparasites such as leeches are even more hateful, they can bite people's skin, suck people's blood, and not only cause "bloodshed", but also cause the risk of infection.
Also, don't underestimate the power of nature.
If there are accidents such as cramps, choking, drowning, etc., it is difficult to get rescued in the first place, and you will face the risk of drowning.
In addition, heavy rains often fall in summer, and wild ditches and streams are prone to sudden flooding, causing natural disasters such as flash floods and mudslides. Especially in flash floods, the river is calm and clear one second, and the next second it begins to be turbid, and the flood comes, almost instantaneously.
Because the streams and wild river ditches are relatively narrow, the water flow speed will be very fast when a flash flood occurs, and it is difficult for people to swim out of the water, but it is easy to be swept away by the current, and they may hit the rocks along the way and be injured, or they may be swept into the bottom of the water and suffocate to death.
In order to avoid drowning accidents, many wild waters have set up safety tips, such as "the depth of the water is dangerous, no swimming", "beware of drowning", etc., if you see such a reminder sign, you must listen to the advice, stay away from wild waters, and fear nature!
Tips
In the event of drowning, try to stay calm, don't struggle desperately, tilt your head back, then face up, let your mouth and nose expose the water, inhale deeply, exhale shallowly, and stretch your hands to both sides to sink into the water naturally, so that there is a high probability that you can float on the surface of the water and wait for rescue~
