Too much cold food can easily cause diarrhea, abdominal pain and other problems. Summer is suitable for eating some light food. So how to keep fit in summer? What are the common health care knowledge in summer?

1, summer health care knowledge

1, the best condiment-vinegar

Summer is cool and hot, sweating a lot, and being jealous can increase the concentration of gastric acid, help digestion and absorption, and promote appetite.

Vinegar also has strong antibacterial ability, which can kill Staphylococcus pyogenes in a short time. It can prevent intestinal infectious diseases such as typhoid fever and dysentery. In summer, people are prone to fatigue, drowsiness and discomfort. Being jealous will quickly relieve fatigue and maintain abundant energy.

2, the best vegetable-bitter vegetables

High temperature and humidity in summer often make people listless, tired and weak, chest tightness and dizziness, loss of appetite and emaciation. At this time, it is of great benefit to eat hard food. Chinese medicine believes that the reason why people are unhappy in summer is because the summer heat is wet, which not only hurts kidney qi but also sleepy spleen and stomach. Bitter food can balance the body function through its functions of invigorating qi, strengthening kidney, strengthening spleen and drying dampness. Modern scientific research has also proved that Sophora alopecuroides is rich in alkaloids, amino acids, picroside, vitamins and minerals, and has the functions of relieving summer-heat, relieving fever, relieving restlessness, refreshing and invigorating the stomach. Bitter gourd, bitter vegetable, lettuce, celery, dandelion, lotus seed and lily are all good choices.

3. The best soup-tomato soup

Drinking tomato soup in summer can not only get nutrition, but also replenish water, killing two birds with one stone. Tomato soup (cooked and cooled) contains lycopene, which has certain anti-prostate cancer and heart protection effects, and is most suitable for men to drink.

4, the best meat-duck meat

Don't think that you can still make up for it by eating only light food in summer. The key is to choose the right supplement. I recommend duck meat to you here. Duck meat is not only rich in nutrients such as protein, which is badly needed by human body in summer, but also can prevent and treat diseases. The secret is that ducks are waterfowl, and their nature is cold. According to the treatment principle of "heat is cold" in traditional Chinese medicine, it is especially suitable for people with low fever, physical weakness, less food, dry stool, edema and other internal heat in summer. Stewed ham and sea cucumber with duck meat, the stewed duck juice is conducive to nourishing the yin of the five internal organs; Duck meat and glutinous rice porridge have the functions of nourishing stomach, enriching blood and promoting fluid production, which is of great benefit to physical weakness after illness; Stewed duck with kelp can soften blood vessels, lower blood pressure and prevent arteriosclerosis, hypertension and heart disease. Stewed ducks and bamboo shoots can cure hemorrhoid bleeding.

5, the best drink-hot tea

In summer, drinks are essential. The first choice is not all kinds of cold drinks, nor beer or coffee, but very ordinary hot tea. Tea is rich in potassium (the average content of potassium per 100g of tea is green tea 10.7mg and black tea 24. 1mg), which can quench thirst and relieve fatigue. According to the experiments of British experts, the cooling capacity of hot tea is much higher than that of cold drinks, and it is the best in summer drinks.

6, the best nutrient-vitamin E.

Vitamins can make you spend the summer safely, and the "best" crown belongs to vitamin E. German scientists emphasize that people will encounter three major dangers in summer, namely strong sunshine, ozone and fatigue, and vitamin E can minimize these three dangers. Malt, bran bread, walnut sauce, dairy products and other foods are rich in vitamin E, which can be arranged in summer. If necessary, you can also take vitamin E tablets, and 15-60 mg per day is enough.

7. The best exercise-swimming

The best exercise in summer is swimming. Swimming can not only exercise hands, feet, waist and abdomen, but also benefit internal organs such as heart, brain, lungs and liver. It is particularly beneficial to blood vessels and is known as "vascular body *". In addition, because the heat consumed in water is obviously higher than that on land, swimming can also reduce excessive weight and achieve the effect of bodybuilding.

8, the best color-red

Many people think it is best to wear white clothes in summer, but in fact it is better to wear red clothes. The secret is that red visible light has the longest wavelength, which can absorb a lot of ultraviolet rays in the sun, protect the skin from harm, and prevent the skin from aging or even cancer, while other colors (including white) have a weak effect. As for fabrics, blended T-shirts are the best, and the best blending ratio is 33% cotton and 67% polyester.

9, the best cool "facilities"-fans

From the point of view of fitness, cooling "facilities" are the best fans. Although the fan is an antique, its fitness effect is incomparable to any other modern cooling equipment. Fan shaking is a kind of exercise, which can exercise limbs (if you consciously switch to left-handed fan shaking, you can also get the effect of activating the right brain, developing the potential of the right brain and preventing stroke). At the same time, fans got the most comfortable wind.

10, the best health care measure-regular sleep

The sunshine is long in summer, early in the morning and late in the evening. Therefore, people's daily life and schedule should be adjusted accordingly. It is better to go to bed late and get up early, and get up and sleep as regularly as possible. "Timing" is the requirement of the internal biological clock. If it can be timed all the year round, it can create a "dynamic stereotype" and make the body have the best adaptability and predestination. Set yourself a strict time to get up and go to bed in summer, and don't violate it for no reason, even if it is a rest day. The best bedtime in summer is 22: 00-23: 00, and the best waking time is 5: 30-6: 30. The hot weather in summer can easily affect people's sleep, but once they get into the habit of getting up regularly, it is easier to eliminate the interference of climate on sleep. When they wake up naturally and comfortably in the morning, the biological clock in the body will not "go wrong" and various physiological rhythms will run safely.

2. How to eat ice healthily in summer?

First of all, you can't eat ice

1. Premenstrual period and menstrual period

The uterus is easy to contract, leading to dysmenorrhea or menstrual blood is difficult to eliminate, and the problem of irregular menstruation will occur for a long time.

Step 2 after a meal

The temperature in the stomach drops sharply, which is easy to cause abdominal distension, indigestion and even colic and diarrhea.

3. After strenuous exercise

It can lead to sudden contraction of gastrointestinal blood vessels, causing diarrhea or abdominal pain.

Tip: Ice can also irritate the throat. Asthma patients should not eat more to prevent asthma recurrence.

Second, the best time to eat ice

It is more appropriate to eat ice when it is sunny from noon to 3 pm, but avoid 1 hour before or after meals.

Third, the suggestion of ice beverage nutritionist

1. bright ice: most of them add too much artificial pigment, which is not good for health.

2. Chocolate drinks: most of them are concentrated, and the sugar content of small 1 spoon is so high that it even contains emulsifiable concentrate or pigment.

Fourth, the best way to eat shaved ice

1, drain soup, less sugar water

Most ice materials will be boiled with sugar, so please drain the soup as much as possible, or simply don't add sugar water, which will be healthier.

2. Save the sauce if you can

Too high sweetness will make your weight loss plan fall short. You'd better choose something with low sweetness to avoid getting thirsty. You can also use freshly squeezed juice, which is ultra-low in calories and tastes fresher.

3. Starch ice materials should be suitable.

Mung beans, red beans, taro and other popular traditional ice materials are staple foods, with high starch and calories, but enough is enough.

Five, the best way to eat iced drinks on the market.

1, multiple flavors = multiple calories

Chocolate sandwich+crust+nuts = high calorie. The more layers of taste overlap, the higher the heat associated with processing methods or ingredients, and the lower the relative heat of pure taste.

2. The more water = the less heat.

High concentrations of whipped cream and caramel are the representatives of high calories. Water-rich shaved ice and smoothies also reduce a lot of calories, which is a good partner for enjoying the cool in summer without getting fat.
