It was the dog days in an instant.
The specific time of the dog days in 2017 is as follows
Head Volt: July 12, 2017
Zhongfu: July 22, 2017
Three volts: August 11, 2017
These 30-odd days will be the hottest period of the year.
There are various folk opinions about three-volt health preservation. Whether these practices are effective or not, regardless of whether they are effective or not, but there are some taboos in the dog days that really need to be mentioned to readers and friends.
The following five things need special attention.
Avoid exposure to the sun
Sunburn is only one aspect. Skin sunburn, photoaging, wrinkles and even skin cancer are the greater risks brought by exposure to the sun.
Ultraviolet rays in sunlight can cause skin peeling, erythema, and even blisters. UVA in ultraviolet rays can penetrate glass, penetrate dermis, destroy collagen and elastic fibers, make skin aging ahead of time, and even cause skin cancer.
In addition to skin, strong sunlight can also damage eyes. If we do not do enough protection, ultraviolet rays may cause damage to eyeball structures such as lens, retinal macula and cornea.
1. Ultraviolet rays are strongest from 10: 00 a.m. to 2: 00 p.m. You should avoid going out during this period.
2. When you go out, choose suitable clothes, such as clothes with long sleeves and standing collars. In addition, damp clothes have less sun protection.
3. Generally speaking, it is enough to use SPF15 or so and PA + + or so sunscreen when going out everyday.
4. It is suggested to go to a regular optician’s shop and choose sunglasses with qualified quality and clearly marked function of blocking ultraviolet rays.
Avoid water shortage
Generally speaking, in order to maintain normal physiological function, each person needs about 1.5 litres per day.
However, the daily water demand can be increased to 2 to 16 liters in high temperature environment or after exercise work and under the condition of sweating a lot.
Water is the source of life. When the body needs it, it must be satisfied.
If there are kidney stones, gout, diabetes and other conditions, drinking more water can also achieve the effect of prevention and treatment.
But one thing, when you are thirsty, don’t drink water too fast, otherwise your stomach will feel full and uncomfortable.
As for drinking what water, the most recommended is always plain boiled water. Remember to replenish water in hot summer and drink slowly in small sips to relieve summer heat.
Avoid greed for cold
This article does not mean that the air conditioner cannot be turned on, ice water cannot be drunk, and ice cream cannot be eaten, but rather that one should be moderate and comfortable according to one’s actual situation.
Low temperature does not cause arthritis, but if arthritis exists, too low a temperature does make joints feel painful and uncomfortable.
Therefore, it is suggested that the temperature difference between indoor and outdoor should not exceed 7 degrees, and it is more appropriate to set the temperature of the air conditioner at about 25 degrees, and it is better not to blow cold air directly at the air conditioner.
Many people are accustomed to drinking hot water and are very afraid of drinking cold water. But in fact, our bodies are not so fragile. Drinking a few mouthfuls of ice water will not reduce the core temperature of our bodies. The so-called claim that drinking cold drinks and eating ice cream will make our bodies [cold] is just speculation and rumors, and there is no definite evidence.
If you feel too cold, your body will feel uncomfortable, then don’t eat it. If you feel a little cold, it will relieve the summer heat and satisfy your needs, and you won’t feel uncomfortable after eating and drinking, you can drink boldly and safely without any worries.
However, due to the high sugar content and energy of ice products, friends with hyperlipidemia and diabetes should be careful not to eat too much. In addition, if you eat sweet ice products well, you’d better rinse your mouth.
The greed for cool in the subtitle is still a matter of quantity. Take your own body feeling as a reference, just don’t be greedy.
Avoid sedentary sitting
When it gets hot, people become lazier.
Stay in a cool room, nest in the sofa, watch TV with watermelons, and don’t want to get up when sitting.
The 2016 edition of the American Diabetes Association’s guidelines clearly states:
Everyone should reduce sedentary time, especially avoid sitting for more than 90 minutes.
Sitting for a long time can also easily lead to swelling of legs and feet, thrombosis of lower limbs and accelerate spinal aging.
Sitting for a long time is harmful, so it is best to get up and take activities every half hour.
Change a cup with a small volume to drink water, and when the water is finished, you will get up to pick up the water. This will not only exercise your muscles and bones, but also drink more water, killing two birds with one stone.
When the sun does not rise in the morning or the summer heat dissipates at night, you can go out for a walk and exercise, or do square dancing to exercise your muscles and bones.
Avoid leftovers
High temperature, bad appetite, easy leftovers.
The temperature is high, bacteria multiply rapidly, and leftovers are easy to deteriorate.
This summer, if the leftovers are left at room temperature for one night… the taste of the food the next day is only sour and refreshing!
Try not to leave vegetarian and cold dishes. Vegetables are more likely to produce nitrite than meat and are also vulnerable to bacterial contamination.
Cover the leftover dishes with plastic wrap and put them in the refrigerator as soon as possible. Even if you put the refrigerator in, it is best to finish it in one day.
No matter what is left is meat or vegetarian dishes, after taking them out of the refrigerator, remember to heat them thoroughly before eating them.
Of course, the best way is to cook as much as you eat, not leftovers in summer.
Have readers remembered the [taboos] of these five dog days?
Green trees are shady and summer is long.
The balcony reflected into the pond.
The crystal curtain is moving and the breeze is blowing.
Full of roses and a courtyard of incense.
May these suggestions help everyone to have a healthy and comfortable summer.
