Women should remember the ten commandments for health preservation in summer

Even in the hot summer, you still need to take good care of your health. Remember the following ten commandments to help you spend the summer in good health.

Not suitable for sitting on wood

As the saying goes, "Don't sit on stone in winter and don't sit on wood in summer." In summer, the temperature is high and the humidity is high. Wood, especially wood, chairs and stools that have been left outdoors for a long time, is exposed to dew and rain and contains a lot of moisture. When exposed to the sun, the temperature rises and it will radiate moisture and heat, making people susceptible to skin diseases, rheumatism, arthritis, etc.

Don’t eat too much cold food

In the hot summer, if the gastrointestinal tract is stimulated by a large amount of cold food, it will speed up peristalsis, shorten the residence time of food in the small intestine, and affect the body's absorption of food nutrients. At the same time, due to the high temperature in summer, the heat in the body is not easy to dissipate, and the temperature in the gastrointestinal tract is also high. If suddenly stimulated by cold, it can cause gastrointestinal cramps and cause abdominal pain.

It is not suitable to sleep outdoors at night

In midsummer, the sweat glands in the body continuously secrete sweat to dissipate the heat in the body. After falling asleep, the body is in a relaxed state and resistance is temporarily reduced. If it is night and the temperature drops, and a cold wind blows, dew will accumulate on the body, which can easily cause headaches, abdominal pain, joint discomfort, and cause indigestion and diarrhea. Sleeping outdoors at night also makes it easy to be bitten by mosquitoes, which may lead to contracting diseases such as encephalitis.

Do not miss a nap

In summer, the days are long and the nights are short, the temperature is high, people's metabolism is vigorous, their energy consumption is high, and they are easily fatigued. Coupled with the hot nights, restless sleep leads to insufficient sleep. Therefore, taking a nap for one or two hours at noon is very beneficial to your health. It can give the body's systems a rest and is also a good measure to prevent heat stroke.

The electric fan should not be blown for too long

Using an electric fan for too long will disrupt the balance of sweating, causing headaches, dizziness, sore legs and weak hands, and general discomfort. In severe cases, it may also induce other diseases. Sleeping with a fan on on a hot summer night can make you more likely to catch a cold. The elderly and children should pay special attention.

The air conditioner should not be turned on too high

Air conditioning can bring people a comfortable environment. However, if the temperature difference between indoor and outdoor is too large, people will find it difficult to adapt to the temperature changes indoors and outdoors and are prone to catching a cold. Moreover, if the temperature difference between indoor and outdoor is too large and attention is not paid to indoor ventilation, the indoor air will become turbid, causing various pathogenic microorganisms to breed. If a person's body resistance is reduced, he or she is prone to illness. Therefore, the temperature difference when using air conditioning in summer should not be too large. It is best to be between 5-8 degrees, and the maximum should not exceed 10 degrees.

Not suitable for "rapid cooling"

In the hot summer, people like to take a cold shower to "cool down quickly" in order to eliminate sweat and heat as quickly as possible after going out. However, since people absorb a lot of heat under the sun, such "rapid cooling" causes the pores of the whole body to close quickly, so that the heat cannot be dissipated and is retained in the body, causing high fever. The capillaries in the brain will also contract rapidly, causing insufficient blood supply, making people dizzy and even causing shock in severe cases. Moreover, the body's resistance is reduced at this time, and colds will "take advantage of the cool to enter." Therefore, the best way is to wipe off the sweat on your body first or wait for the sweat to dry before rinsing.

Don't drink too fast if you are very thirsty

People sweat a lot in the summer. If some people drink a lot of water at once, it will increase the burden on the heart, reduce blood concentration, and even cause symptoms such as palpitations, shortness of breath, and sweating. If you are extremely thirsty, you should drink a small amount of water first and then wait for a while before drinking again.

It is not advisable to use beverages instead of boiled water

Beverages such as soda, juice, and cola contain more saccharin and electrolytes. These substances can cause adverse stimulation to the stomach, affecting digestion and appetite. If consumed in large quantities, they can also increase the filtration burden on the kidneys and affect kidney function. Moreover, excessive intake of sugar will increase the body's calories and make people obese. Therefore, it is not advisable to drink too many beverages in summer. It is best to drink boiled water, especially for children and the elderly, who should drink less beverages and more water.

It is not advisable to wear sunglasses that are too dark or too light.

Sunglasses can prevent ultraviolet rays from damaging the eyes, but if the lens color is too dark, it will affect vision due to unclear vision; if the lens color is too light, ultraviolet rays can still pass through the lens and damage the eyes. Therefore, when choosing sunglasses in summer, you should allow between 15%-30% of visible light to pass through gray or green lenses. This will not only protect against ultraviolet rays, but also provide optimal visual clarity and minimal color changes when looking through external objects.
