What to bring to the beach
Umbrellas, sunglasses, sunscreen, swimsuits, swimming trunks, swimming caps, water mirrors, bath towels, slippers, all of which are indispensable.
Do not swim in the non-swimming area. The water in the non-swimming area is complicated, and there are often reefs, water plants, silt and whirlpools. A little carelessness may cause accidents.
Therefore, before launching into the water, you must do a good job in local investigation and research, be aware of it, and keep away from water plants, reefs, swirling currents and silt as much as possible. Do not drink alcohol before swimming. After swimming, a large amount of glucose stored in the body will be consumed, resulting in hypoglycemia.
In addition, alcohol can inhibit the normal physiological function of the liver, hinder the conversion and storage of glucose in the body, and cause accidents. At the same time, alcohol will affect the brain's judgment ability, and increase the chance of swimming accidents. To avoid exposure to the sun after going ashore, pay attention to protect the skin, in order to avoid violent sun exposure, it is best to apply sunscreen.
Before sea bathing, make preparations on the shore, and then soak the skin in shallow water to make the body suitable for the water temperature. Please do not climb the reef when sea bathing to avoid being scratched by oysters.
Avoid swimming for too long. The skin generally has three reaction periods to cold stimulation. The first stage: After entering the water, the skin blood vessels constrict and the complexion is pale due to the stimulation of cold. The second stage: After staying in the water for a certain period of time, the blood flow on the body surface expands, the skin changes from pale to light red, and the skin changes from cold to warm.
After staying for too long, the body temperature and heat dissipation are greater than the heat generation, and the skin appears goose bumps and chills. This is a taboo period for summer travel, and the water should be released in time. The duration of swimming should generally not exceed 1.5-2 hours.
