Beware of three major misunderstandings during summer travel

When traveling in summer, you should beware of three major misunderstandings:

Myth 1: The darker the sunglasses, the better they can protect your eyes. Experts say that, in fact, if the lens color is too dark, it will affect the visibility of the eyes, making the eyes susceptible to damage. Experts suggest that the lenses of summer sunglasses should be able to pass through 30% of visible light, preferably gray and green, because these colors can not only resist ultraviolet radiation, but also have the best visual clarity.

Myth 2: The less clothes you wear when traveling, the cooler you will be. In fact, being shirtless can only increase the radiation and conductive heat dissipation of the skin when the skin temperature is higher than the ambient temperature. When the temperature is close to or exceeds 37°C, the skin will not only be unable to dissipate heat, but will absorb heat from the external environment. Therefore, being shirtless in midsummer is not a good idea for women. Wearing a short skirt will make you feel hotter. Experts suggest that it is best to travel in light-colored silk clothes.

Myth 3: Drinking beer during travel can relieve the heat and cool down. In fact, when traveling in summer, the human body sweats more and gets tired easily. If you continue to drink beer, the "hot" feeling caused by alcohol will aggravate thirst and sweating and reduce people's thinking ability. Experts suggest that you can drink some active vitamin drinks to quench your thirst and relieve the heat.
