Facing the scorching sun, going out for three minutes will turn into barbecue weather. Are you okay?
Is it already as hot as the corn in the following picture?
Don’t worry, Dr. Clove will share with you some cool and refreshing tips, so that everyone will not cook barbecue this summer, and it will be cool and refreshing for a summer!
Step 1 Choose the Right Clothes
Because you sweat a lot in summer, sweat evaporation can take away the heat on the body surface, and the material of clothes will affect the evaporation of sweat, so it is very important to choose the material of clothes.
We should choose clothes that are breathable and easy to drain moisture. For example, we can choose clothes made of natural materials such as silk, cotton and hemp, or synthetic fiber materials with strong breathability.
Step 2 Wear the right color
Which color is cooler, dark or light?
The answer may be unexpected. In most cases, it is dark. More specifically, it is loose dark clothes.
Wearing clothes to be cool depends on two aspects. First, it helps reduce the heat transfer from the outside world to the human body. Second, it helps increase the heat transfer from the human body to the outside world.
If it is in direct sunlight, no wind and the external temperature is higher than the body temperature, the main consideration is to reduce the external heat transfer of clothes. It is true that light-colored clothes absorb less heat from the outside and are cooler.
But more often than not, we will stay in a cool, windy place where the external temperature is lower than the body temperature. In this case, the main consideration is to increase the heat emission of the human body. At this time, it is cooler to wear dark clothes, especially loose and breathable dark clothes.
Because dark clothes absorb more heat from the human body, helping the human body to radiate heat to the outside world. At the same time, because dark clothes absorb more heat, the air convection between clothes and skin is strong, which can accelerate the evaporation of sweat on the skin surface, thus taking away more heat from the human body, and people will naturally feel cooler.
3. Protect yourself
Avoid direct sunlight, wear a hat and umbrella, and try to stay in a cool place. In addition, the hat should have a large edge, so there is enough shadow to avoid direct face shooting.
Men need to be reminded that it is not necessarily cooler to be shirtless in summer. Sometimes, if you are shirtless and exposed to the sun, you will feel hotter. Because if the ambient temperature is close to or even higher than people’s body temperature (about 37 ℃), people cannot effectively dissipate heat through conduction, but are easy to absorb heat from the outside world, making people feel hotter and hotter.
In addition, shirtless in hot weather, make the skin surface heat increase, sweat more. And most of these sweats have not yet evaporated, they converge into big sweat flowing. This reduces the evaporation of sweat, so that the heat that could have been taken away by sweat evaporation remains in the body, people will feel hotter.
Step 4 Drink plenty of water
Drinking plenty of water is also one of the secrets of keeping cool in hot summer. But there are several points to remind everyone:
Take a small sip and drink slowly. Don’t pour a lot of water at one time, which will swallow a lot of air and easily cause hiccups or abdominal distension.
Don’t wait for thirst before drinking water. When people feel thirsty, the degree of water shortage is more serious. Therefore, we should form the habit of drinking water and take the initiative to drink water every 2 ~ 3 hours.
Generally speaking, for healthy people with little activity, it is more suitable to drink 2,000 ~ 2500 milliliters of water every day in summer. If the amount of activity is large and the weather is especially hot, you can drink more appropriately.
It should be noted that for people with heart and kidney diseases, how much water to drink every day needs to follow the doctor’s instructions.
Step 5 Use Spray Flexibly
We can put water in the spray and spray it on the skin.
Like sweat evaporation, when the water on the skin evaporates, it can take away some heat, which is equivalent to creating a small air conditioner on the skin.
We can also add some lemon, mint and citrus flavors to the spray. These fresh smells can help people cheer up and drive away the dryness and heat in summer.
Step 6 Take a bath
If conditions permit, taking a bath is a good choice. In addition to removing uncomfortable sweat and dirt from the skin, bath water can also take away a large amount of heat through conduction and make people feel cool.
It is necessary to remind everyone not to take a bath with cold water immediately after being exposed to the sun, so as not to cause skin cold and blood vessel contraction, which is not conducive to body heat dissipation.
