Why do people feel tired in summer?
Why do people feel tired in summer? The adjustment of biological clock, due to the change of solar orbit in summer, leads to the change of geomagnetic field, which affects people's biological clock, so people will constantly adjust their biological clock automatically in summer. A good biological clock 1 week can be adjusted, and a bad biological clock needs 1-2 months to be adjusted. Sleep must be regular.

Why do people feel particularly tired in summer? First of all:

Although the sunshine is strong in summer, there are too many opportunities to lose it: air conditioning, cold drinks, cold fruits and vegetables, hair blowing, sweating (injury to body fluids and gas consumption), lack of sleep, poor appetite, excessive physical strength and so on. These will damage the spirit of the sun and reduce the function of the human body. Therefore, in summer, many people will feel tired, lack sleep, easily catch a cold, get gastroenteritis, even heatstroke and stroke.

Second:

Sweating in summer is easy to cause imbalance of body fluid metabolism. The balance between water and electrolyte is an important factor to keep the internal environment relatively constant. If you sweat a lot, you will lose too much water, sodium chloride and water-soluble vitamins (mainly vitamin B 1 and C), which will lead to imbalance of water and salt metabolism, acid-base balance and osmotic pressure. Due to a lot of perspiration and chloride ion loss, the chloride ion reserve necessary for the formation of gastric acid in the blood will be reduced, resulting in a decrease in the acidity of gastric juice; Drinking plenty of water because of thirst will dilute stomach acid. These changes will directly or indirectly affect the digestive function and cause loss of appetite. In addition, due to the high temperature, the blood in the body is mostly concentrated on the body surface, which is easy to cause digestive tract ischemia, inhibit saliva secretion, reduce amylase activity, and reduce gastric juice secretion, causing loss of appetite and digestive dysfunction.

Why do people in summer feel that the metabolism of tired people is accelerated? In addition, people keep sweating in hot weather, and a lot of salt is excreted, which of course makes them feel tired.

Why do people feel irritable in summer? When the temperature rises, the air will become hot and humid or dry, which will affect the blood supply and oxygen supply to the brain, resulting in irritability, and its mechanism is equivalent to irritability caused by high pressure and fever after surgery.

Why do people feel tired and lack potassium in summer, which easily leads to a nap in summer?

As the saying goes: "Spring is sleepy and autumn is lacking, and summer is a nap." Although this is all fatigue, the reasons are different. "Summer nap" is also called "summer burnout" in medicine. It is because of the hot and high temperature in summer that people sweat a lot, and a lot of potassium can be excreted with sweat, and potassium can not be replenished in time, which leads to fatigue and listlessness in summer.

Potassium is an indispensable element in human body, and its main function is to maintain the normal functions of nerves and muscles. Therefore, once the human body lacks potassium, normal exercise will be affected.

Potassium deficiency in summer not only reduces energy and physical strength, but also reduces heat resistance, making people feel tired and weak. Severe potassium deficiency will lead to acid-base imbalance, metabolic disorder, arrhythmia and muscle weakness. At this time, some people drink too much salt and boiled water in order to make themselves sweat less. But I don't know, it is easy to increase the burden on the heart and make the potassium and sodium in the body unbalanced.

Pay attention to some foods with high potassium content. Among food crops, buckwheat, corn, sweet potato and soybean have higher potassium content. Among fruits, bananas contain the most potassium; Among vegetables, spinach, amaranth, coriander, rape, cabbage, celery, green onion, lettuce, fresh peas, edamame and so on. Rich in potassium and seaweed.

Summer health: calm and cool naturally.

It's hot and humid in summer, which makes people fidgety, and various summer diseases begin to breed. Peace of mind is naturally cool, and it is most important to prevent irritability in summer. In addition, in the diet, it should be particularly light and drink more soup; Don't try to eat too much iced food for the time being, drink a few cups of warm water early and do aerobic exercise properly. Some people like to drink herbal tea, but it's a three-point poison. Drinking tea should be based on personal physique, in moderation, not in excess. Tieguanyin, green tea and Pu 'er tea are suitable for drinking in summer.

Washing your face in hot summer is the most taboo for cold water.

What is the biggest taboo for washing your face on a hot day? Just wash your face with cold water! Everyone knows that oil will solidify when it meets cold water, so imagine that when your face is full of sweat, greasy and dust, you just wash your face with cold water, which will undoubtedly greatly affect the effect of washing your face and have future troubles.

Someone came home from outside sweating, hoping to be cool and happy, so he turned on the tap and washed his face with cold water. As we all know, the face panel full of sweat has a higher temperature. If you don't cool down, you will suddenly get cold water, which will cause the pores of the panel to shrink, so that the oil and sweat in the pores can't be cleaned up in time. The consequence of this is that the pores of the skin become larger, and sensitive skin may even become acute inflammation! Oily panels are more prone to acne and acne.

In view of the fact that many women need to use sunscreen or sunscreen in summer, there will be more oil stains at the end of the day. When washing your face, it is best to use the double washing method-that is, first remove makeup and then wash your face, with or without makeup.

Because the general makeup remover has good oil solubility, it can dissolve the dirt in pores and prevent acne. After using makeup remover, you should choose a foaming cleansing product and carefully clean the panel with warm water.

Jealous all summer.

In the hot season, due to lack of sleep, poor diet and excessive sweating, the human immune ability is obviously reduced, and people often feel tired and weak. Coupled with the influence of various bacterial infections, various diseases, especially gastrointestinal diseases, are prone to attack. High-quality brewed rice vinegar has special effects on health care in summer.

Vinegar has a magical detoxification effect. On the day of usurping the medical forest, vinegar "clears the liver and closes the heart." Treat coma, wake up, nourish lungs, make sounds, kill fish and kill insects. "The existence of a large number of organic acids in fermented vinegar not only makes the sour taste of mature vinegar mellow, long, soft and delicious, but also is a natural' killer' of various bacteria. There are many kinds of bacteria in summer, and toxins are easy to accumulate in the body, which makes people prone to gastrointestinal diseases. Adding aged vinegar to cold salad or cooked vegetables is simple, delicious and sterilization, which can effectively avoid the infection of gastrointestinal pathogens. In order to meet this market demand, Hengshun Group developed a special cold companion vinegar and put it into the market, which was deeply loved by people from all walks of life. Amino acids, acetic acid, lactic acid, malic acid, succinic acid, glycerol and aldehydes in vinegar are not only necessary for human vitality and metabolism, but also beneficial to the enhancement of liver's own detoxification function.

Vinegar can stimulate people's appetite and help prevent heatstroke and cool down. Modern scientific research has found that volatile substances and amino acids in vinegar can affect the nerve center of human brain, make digestive organs secrete a lot of digestive juice, and help to enhance digestive function. Therefore, eating high-quality mature vinegar in high temperature season can play an appetizing role. Therefore, drinking vinegar is very popular in many cities such as Shanghai. Fashion women mix vinegar with red wine, white wine, mineral water, sprite and other drinks to make delicious, colorful and nutritious cool drinks, and give them poetic names such as "beauty in powder" and "beauty in hazy".

Vinegar helps to relieve fatigue. Summer fatigue is easy because: under normal circumstances, the human body's internal environment is maintained in a neutral or weakly alkaline state. However, when working and working for a long time or having a bad rest, a lot of lactic acid will be produced, and people will feel tired. Acetic acid in aged vinegar is beneficial to the further oxidation of lactic acid and its transformation into water and carbon dioxide. Water continues to participate in the metabolism of the body or is converted into urine and sweat, and carbon dioxide is excreted from the lungs. Therefore, vinegar has a unique miraculous effect of preventing and eliminating fatigue.

Top Ten Best Summer Life

The climate in summer is hot, germs multiply and grow rapidly, and there are many factors that affect health. So, in order to spend the summer safely, the following ten "best" in summer life can help you.

1, the best condiment-vinegar: it is cool and hot in summer, sweating more, 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 high humidity in summer often make people listless, tired and weak, chest tightness and dizziness, loss of appetite, body weight loss. 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. Best for men.

4, the best meat-duck meat: don't think that you only eat light food in summer, and you can still make up in summer. The key is to choose the right tonic. 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: summer can not be separated from drinks, the first choice is neither a variety 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" laurel 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 pills of vitamin E, 15-60mg per day is enough.

7. The best exercise-swimming: The best exercise in summer is swimming. Swimming not only exercises the hands and feet, waist and abdomen, but also benefits the internal organs, such as the heart, brain, lungs and liver, especially the blood vessels, and is known as "vascular gymnastics". 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 that wearing white clothes in summer is the best, in fact, wearing red clothes is better. The secret lies in that red visible light has the longest wavelength, which can absorb a lot of ultraviolet rays in the sun, protect the panel from damage and prevent the panel from aging or even cancer, while other clothing colors (including white) have a weak effect in this respect. As for fabrics, blended T-shirts are the best, and the best blending ratio is 33% cotton and 67% polyester.

9. The best cooling "facility"-fan: From the perspective of fitness, the cooling "facility" is the best fan. Although the fan is an "antique", its fitness effect is unmatched by 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 measures-time to get up and go to bed: long sunshine in summer, early in the morning and late at night. 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, and they will wake up naturally and comfortably in the morning, so that the biological clock in the body will not "go wrong" and various physiological rhythms can be carried out safely.

Why do people feel tired and dry in summer? When the weather is dry in summer, the human body will easily lack water. Man is made of water. People's moods are often influenced by the outside world, so they often feel tired and dry in summer.

Why do people feel cold in winter, but they don't turn on the air conditioner immediately? When they first go to bed every night, they will feel that the quilt is very cold, and it will take some time to warm the whole quilt. Some people, even with thick quilts, can't reach their frozen feet. In this case, there are usually more women than men. People in this situation are prone to peripheral vasospasm. When they encounter cold air or cold water, the blood vessels in their hands and feet contract, the blood circulation is not smooth, and their hands and feet are easy to get cold and purple. In addition, it may also be because the sympathetic nerve function is not good, which leads to the inability to tighten muscles and produce heat and cold resistance when it is cold. People's body temperature is kept between 36 and 37 degrees Celsius. When the human body's panel touches the outside temperature, it will be directly transmitted to the life center of the medulla oblongata, which controls breathing, heartbeat and body temperature. In hot weather, the body temperature control center will dominate the excitement of sympathetic nerves, so that the capillaries and sweat holes of the panel will be opened to dissipate heat and sweat; When you feel cold, sympathetic nerves will cause shivering in all parts of limbs, including muscles near the jaw, which will make muscles and fat cells generate heat energy due to contraction and resist the chill. This is why people will tremble when they feel cold. People are warm-blooded animals, so basically there should be no question of "who is more afraid of cold". At the same temperature, some people may be particularly afraid of the cold because of their different subjective feelings. Of course, the fat layer can isolate the low temperature, but because the effect of fat cells on heat production is worse than that of muscles, people with thick fat may not be afraid of cold, but may be more afraid of cold! Some diseases will affect the body's inadaptability to cold and heat. For example, patients with hyperthyroidism are quite heat-resistant because of excessive excitement and metabolism of sympathetic nerves; On the contrary, patients with hypothyroidism cannot generate enough heat energy to keep out the cold because of poor sympathetic nerve function. There are also long-term smokers. Because of lack of oxygen in the body, the surrounding microvessels are prone to poor circulation. It is easy to get cold when the arterial microvasculature is poor. However, if the venous microvessels are not unobstructed, although there is no feeling of being particularly afraid of cold, the blood vessels cannot expand and the blood cannot circulate, resulting in local hypoxia, and hands and feet are prone to chills. Usually, urban "lazy people" who "can lie down and don't sit, but can sit and don't stand" will also have the problem of not being cold-tolerant because of the decrease of basal metabolic rate. Women are afraid of the cold. Generally speaking, women are more afraid of the cold than men. Not long ago, two experts from an American institute of human health conducted a group experiment on female volunteers. The experimental report found that people with low cold tolerance have obviously insufficient iron content in their blood. The main cause of iron deficiency in women is menstruation, which leads to a large loss of iron. As we all know, iron is an important raw material for producing hemoglobin, which is the main functional substance in red blood cells and is responsible for the transportation and metabolism of oxygen in the body. Iodine and tyrosine are the main raw materials for making thyroxine. Iodine needs to be continuously ingested from food, while tyrosine is generally synthesized by itself in the body. Long-term iodine deficiency will affect the synthesis of thyroxine and reduce the body's ability to keep out the cold. How to warm hands and feet ● Soaking hands and feet with hot water before going to bed can not only promote the circulation of vascular endings, but also help sleep. ● After bathing or soaking in hot water, put on socks to keep warm immediately after drying. ● If women are often afraid of cold feet in winter, they can put hot water, rice wine and ginger slices in a bucket (the ratio of hot water to rice wine is 1: 1). Watching TV or getting off work in winter helps to improve women's fear of cold. Doing sports is not afraid of cold weather. When you eat too much and exercise too little, it is easy to accumulate excess fat in your body. At this time, you can do more exercise, which can not only consume too much fat, but also strengthen blood circulation and warm your body. What to eat is not afraid of cold. Choosing warm food or medicinal materials for tonic in winter can make the body's blood circulation smooth and qi and blood active, which can achieve the effect of keeping out the cold. Foods with warming function are generally red and sweet foods, or spicy condiments and foods. These foods have the functions of warming, nourishing and promoting metabolism. Warm food meat suitable for winter: mutton, beef, shrimp, sea cucumber, oyster, eel, venison, chicken liver, etc. Rich in lipids, protein and other meats. Fruits and vegetables: leek, perilla, green pepper, mustard, cabbage, pepper, onion, pumpkin, litchi, peach, longan, onion, ginger, garlic, etc. Others: brown rice, sorghum, sesame, nuts, cashews, walnuts, chestnuts and other drupe foods. When cooking or eating cold food, you can add some spicy spices such as onion, ginger, garlic, pepper, pepper, ginseng, astragalus, dried tangerine peel or Chinese herbal medicine to blend. For example, if you eat cold crabs, you can fry crabs with hot ginger to reduce the coldness of crabs. Common cold foods are loofah, wax gourd, celery, cucumber, kelp, frozen watercress, cabbage and so on. When cooking, you can use appropriate seasonings such as onion, ginger and garlic to achieve the effect of neutralizing the cold. In addition, you can also use Lycium barbarum, red dates, ginseng, longan pulp or ginger to make tea, which can also play a role in keeping out the cold.

Adopt it

Why are people tired in summer? In summer, the body's metabolism is faster and its consumption is higher. The human body will naturally feel very tired when it is consumed in large quantities. Too high a temperature will also make the brain feel uncomfortable and slow down, so it will feel tired.
