What's the appropriate temperature for going to the seaside?

In hot summer, many people like to go to the seaside to play. If you want to swim, you must get into the water at the right temperature. So what's the appropriate temperature for going to the seaside? Come and have a look with me.

1, how many degrees is the seaside suitable for launching?

When going to the seaside, the temperature is 22-28 degrees, which is suitable for swimming. The time when the ultraviolet rays of sunlight are strongest (will cause the greatest harm) is between 10 morning and 3 pm. It is best to choose swimming time after 4 pm. Especially people who often work indoors are less exposed to the sun and are more likely to get sunburned.

But try not to swim after 10 at night, or you will lose sleep because of excessive nerve excitement.

2. First, choose the right time to go swimming at the seaside.

Swimming at the seaside can't be continued in bad weather. Try not to go when the tide is high and low. You can choose to go or not to go in the sun according to your own ability.

Swimming at the seaside is no better than swimming in the swimming pool. You should be very careful when the tide rises and falls. It is recommended not to swim in the sea or just surf on the shore at noon. Generally, it is more appropriate to swim in the sea at low tide from 5 to 7 pm. It's not safe to swim after the sun goes down later, without lights.

Don't go swimming at the seaside alone.

Don't be alone, choose a crowded beach and don't go to remote waters. After all, I have just arrived at a beach and I am not familiar with the terrain. At high tide, reefs and rocks may be submerged by seawater, and it is difficult to ask for help if you swim too far or too far. Beginners should try not to go to places where the water depth exceeds their height. For safety reasons, they can also rent swimming rings.

Matters needing attention in swimming at the seaside

1. When you get to the seaside, you should observe first. Remember, you should pay attention to the warning line or warning sign by the sea. Don't cross the warning line, and don't go to the dangerous area mentioned by the warning sign.

2. Make sure there must be lifesavers on duty at the seaside, and then go to the seaside to play. If there is no lifeguard, don't go into the water easily to avoid accidents.

3. People who can't swim will be hung by inflatable objects, which is desirable, but there will also be accidents, that is, what to do if the inflatable ring or swimming ring leaks. Therefore, it is suggested that people who can't swim, even if they use swimming rings to play in the sea, also need people who can swim to follow.

If you are swimming in the sea and suddenly bleed, such as what happened to your feet and limbs, don't stay in the water, but go ashore at once. This is to prevent bloodthirsty creatures in the sea from attacking you.

When playing in the sea, if you find someone drowning and can't swim, don't try to save people, but immediately call out for help. Especially ask a lifeguard or a swimmer for help.

What should I do if I meet a jellyfish while swimming in the sea?

Jellyfish is a kind of jellyfish, which breeds in shallow water in July and August every year and swims to the deep sea after the breeding period. It is a jejunal animal, transparent or translucent, with many tentacles under the umbrella cover and dense spiny silk sacs containing venom. Jellyfish generally don't take the initiative to attack people, but their tentacles will wrap around people and release toxins. Its toxin is composed of various polypeptide substances, and dead jellyfish floating in the sea may also sting people.

If you are stung by jellyfish, you will feel burning or itching, and then erythema and papules will appear in a string, and blisters, petechiae and ecchymosis may also appear. You will often have chills, fever, abdominal pain, burnout and cold sweat within 1-4 hours, and a few will have chest tightness, foaming at the mouth, blood pressure drop, dyspnea and pulmonary edema, and even lead to death in severe cases.

The most important thing to prevent jellyfish stings is to avoid contact with jellyfish, followed by understanding and mastering scientific treatment methods. Once stung, don't rinse with fresh water, because fresh water will promote the release of venom and aggravate the injury. Lighter people should wipe off the tentacles and venom stuck to the skin with towels, clothes and sediment as soon as possible, or rinse with seawater; If possible, alcohol or alkaline (10% sodium bicarbonate) solution can be sprayed on the affected area, and alum can also be applied to the affected area. In severe cases, you should call "120" emergency number in time, so that patients can get timely treatment.
