How to protect yourself from the sun while swimming

Before swimming, you should do enough sun protection. Sunscreen is essential. Choose a waterproof and oily sunscreen. Ordinary sunscreen will be washed away when it comes into contact with water and will not play a sun protection role. Therefore, waterproof sunscreen is the best choice. Of course, you still need to reapply sunscreen within two or three hours.

The strongest ultraviolet rays in the day are between 10 a.m. and 3 p.m., so you should avoid outdoor swimming during this time. However, the ultraviolet rays before 10 a.m. and after 3 p.m. are weaker, so you can swim happily without worrying about getting sunburned. Of course, sun protection is still necessary, which is very important.

Before swimming, you should prepare for sun protection. It is best to apply some oily sunscreen to avoid the sunscreen being washed away by long swimming. Of course, you should reapply sunscreen within two or three hours. It is recommended to use a waterproof sunscreen with an SPF (sun protection factor) of 30 or above to protect your skin. To ensure the effect, apply it every half an hour to an hour.

Dry your body quickly after swimming to reduce water reflection. Water droplets left on the body and in contact with sunlight will also reflect, greatly increasing the chances of your skin being damaged by ultraviolet rays.

Even if you hide in the shade, water can refract ultraviolet rays onto your skin and cause sunburn, so you must take comprehensive sun protection measures and pay attention to sun protection even in the shade.

Choose waterproof sunscreen. Not only pay attention to the SPF multiple, but also be sure to choose one with PA. Generally speaking, outdoor swimming has strong sunlight and lasts for a long time, so the SPF should be 30 or higher, and the protection time is correspondingly longer. Choose PA to protect against UVA. The more " " after PA, the greater the protection strength and duration. PA is super strong protection. You can choose the appropriate sunscreen product according to your needs.

Is swimming good for your lumbar spine?

When swimming, due to the effect of buoyancy, the human body does not need much strength to float in the water, and can move freely with the help of the buoyancy of the water.

The buoyancy of the body puts the spinal bones in a natural horizontal extension state, which is very good for evenly distributing the bearing force of the spine, especially reducing the pressure on the cervical and lumbar vertebrae.

In addition, the water temperature also has a stimulating effect on the muscles, which will speed up blood circulation and metabolism, fully relieve the soreness and numbness caused by cervical spondylosis and lumbar spondylosis, and help to alleviate the disease and restore health.

What to drink after swimming?

After swimming and fitness, don't eat anything greasy or filling right away. It's best to eat some fruits with a clear taste. You can eat some low-sugar cucumbers, cherries, apples, etc. to supplement some energy.

You can eat some whole-grain bread slices, but don't eat bread with too much cheese or cream. Just eat a few slices. After all, it is not a main meal, and its main purpose is to relieve hunger.

Add some low-fat milk to sugar-free oatmeal and eat a little bit. It is very good for the body and also helps to restore the feeling of fullness.

Eating salads made of various vegetables and fruits is also a particularly light and weight-loss side dish. Do not use cream. Just mix it with vinegar, olive oil and a little seasoning and it will taste good.
