Do I need to wear a sun hat to travel to Yunnan?

Yunnan is located in the south of China, on the Yunnan-Guizhou Plateau, where the solar radiation is relatively strong and the ultraviolet rays are also strong. Whenever you travel to Yunnan, you should take sun protection measures. Sun hat is an effective sun protection device.

Damage caused by ultraviolet rays:

As we all know, the sun's exposure will form spots, wrinkles and loose skin, but these are only visible to the naked eye.

Here we are. In fact, it will also cause some damage to cells and genes. Some cells will be killed on the spot, while some injured cells will release a chemical to stimulate capillaries and rupture them, which is what we usually call sunburn. In particular, UVA can penetrate the skin, destroy DNA, make the skin inelastic, and even cause skin cancer in severe cases.

Misunderstanding:

It is not that the higher the temperature, the stronger the ultraviolet rays. First of all, we must clearly realize that ultraviolet rays will not generate heat.

For example, when you are at the seaside, climbing mountains or skiing, the colder you feel, the stronger the ultraviolet rays are. Just like in Kunming, even without the sun.

Ultraviolet rays are also very strong.

Sun protection method:

Playing a parasol, wearing a sun hat and sunglasses are all effective sun protection methods. But playing with a parasol can't stop all the risks of sunburn. In fact, 50% of ultraviolet rays can pass through the awning, and only UVB which can make people feel burning can be isolated, and UVA can penetrate the awning without any difficulty. You'd better buy a good umbrella when you buy one.

Sunscreen that can prevent both UVA and UVB is the best sunscreen. UVB can stimulate melanocytes and make the skin black, while UVA can make the skin allergic and appear spots. Therefore, a product that takes both into account is the best sunscreen.

Sun protection should be comprehensive, not only on the face, but also on the lips, ears and neck. Use professional sunscreen products for lips and sunscreen for neck. If you don't pay attention to comprehensive sun protection, the skin will be uneven after military training and the skin will age faster. Long exposure to the sun makes the skin less soothing. Be sure to make good use of the rest time at noon and apply a wet towel to your face and neck to relieve redness and swelling. Clean your skin at noon and apply sunscreen half an hour in advance to prepare for military training in the afternoon.

In addition, due to the extremely high summer temperature in Xishuangbanna, the best time for xishuangbanna tourism is March and April. Shangri-La is the best place to travel to Yunnan in the hottest time, but the ultraviolet rays are also very strong. Pay attention to ultraviolet protection and protect yourself is the first element of travel.
