4. Coffee can relieve fatigue. To eliminate fatigue, we must supplement nutrition, rest and sleep, and promote metabolic functions, and coffee has these functions.

Three cups of coffee a day can prevent gallstones. For caffeinated coffee, it can stimulate gallbladder contraction and reduce cholesterol which is easy to form gallstones in bile. Recently, researchers at Harvard University found that men who drink two or three cups of coffee a day have a lower risk of gallstones than 40%.

6. Drinking coffee regularly can prevent radiation injury. Radiation hazards, especially electrical radiation, have become the prominent pollution at present. Baba's Indian atomic researchers reached this conclusion in mouse experiments and said it can be applied to humans.

7. The health function of coffee. Coffee has the functions of resisting oxidation, protecting the heart, strengthening bones and muscles, benefiting the waist and knees, stimulating appetite, promoting eating, reducing fat and digestion, inducing resuscitation and removing dampness, promoting blood circulation and removing blood stasis, calming wind and relieving spasm.

8. The influence of coffee on mood. Experiments show that the average person absorbs 300 mg (about 3 cups of brewed coffee) every day, which will have a good influence on a person's alertness and mood.

Disadvantages:

1. Make trouble when you are nervous.

Caffeine helps to improve alertness, sensitivity, memory and attention. But if you drink more coffee than you are used to, you will have the same dose of stimulants, which will cause tension. For people with anxiety tendency, caffeine can aggravate the symptoms of sweating, palpitation and tinnitus.

Aggravate hypertension

Caffeine is often combined with other simple painkillers because of its analgesic effect. However, if you take a lot of caffeine for a long time, if you already have high blood pressure, using a lot of caffeine will only make your situation worse. Because caffeine alone can raise blood pressure, if combined with emotional tension, it will have a dangerous multiplier effect. Therefore, people at risk of hypertension should especially avoid drinking caffeinated drinks when working pressure is high. Some people who drink coffee all the year round think they are immune to the effects of caffeine, but this is not the case. A study shows that after drinking a cup of coffee, the blood pressure can rise for as long as 12 hours.

Caffeine itself has a good diuretic effect. If you drink a lot of coffee for a long time, it will easily lead to bone loss, which will adversely affect the preservation of bone mass and may increase the threat of osteoporosis in women.

Advantages and disadvantages of steamer

What are the advantages and disadvantages of the steamer?

Sweating is a healthy method that many people have experienced. It used to be expensive and troublesome to go to a steaming room when steaming. So people developed a new generation of steaming products-steamer. It is developed by using far infrared technology on the basis of traditional steamer. It not only has all the health care functions of the traditional steaming room, but also is very convenient to use. It can be steamed at home at a much lower cost. Steaming box has many advantages and some disadvantages to human body. Let's take a look at it in detail. Benefits of steamer 1. Improve the microcirculation system of the body, make independent water molecules vibrate freely inside and outside the cell, and then convert them into heat energy, so that the temperature in the deep subcutaneous layer rises slightly, the blood flow speed is accelerated, and capillaries are dilated; The more capillaries are opened, the pressure on the heart can be reduced, at the same time, water molecules can be activated, the oxygen content of the body can be increased, and magical health care effects can be achieved, including adjusting blood pressure; It can also play a certain auxiliary role in the rehabilitation treatment of diabetes, rheumatism and spinal diseases. 2. Reducing blood fat and losing weight Because the excess water, salt and subcutaneous fat in the human body are discharged with sweat after heating and activation, especially when the fat is around 40℃, the water solubility is enhanced and it is easier to discharge, so it has the effect of losing weight. 20-30 minutes of far-infrared light wave bath plus steaming, equivalent to long-distance running 10000 meters. 3. Regulating the health of nervous body fluid depends on the stability of internal environment. To achieve this, neurohumoral regulation mechanism plays a key role. With the accelerated pace of life and fierce competition in modern society, coupled with the deterioration of external environment such as environmental pollution, physical and mental diseases have increased significantly. 8- 1.4 micron far infrared ray can effectively trigger the self-regulation mechanism of human body, balance the regulating function of body fluid and the pH value of human body, and has regulating effect on ulcer, hypertension, hyperthyroidism, migraine, insomnia, asthma, neurological dysfunction and other diseases. 4. Far infrared rays with anti-inflammatory and analgesic effects generated by the far infrared household steamer can form a local light wave ring in the steamer, wrap the human body and penetrate into the human body evenly. The warming effect of far infrared rays can dilate blood vessels in human body, accelerate blood circulation, and increase oxygen supply to painful parts, thus playing an anti-inflammatory and analgesic role, and preventing osteoarthralgia caused by uric acid is too high. 5. If the detoxification microcirculation system is improved, the waste produced by metabolism can be quickly excreted, reducing the burden on the liver and kidneys. These wastes include carcinogenic heavy metals; Lactic acid, free fatty acids and subcutaneous fat that cause fatigue and aging; Uranium ions causing hypertension and uric acid causing pain; Far-infrared sweat steam hyperthermia can discharge the waste produced by metabolism from sweat and achieve the effect of detoxification. 6. Far-infrared radiation to the skin can activate skin tissue cells, stimulate life-active components such as enzymes, amino acids and nucleic acids, and promote the metabolism of melanin particles and phagocytosis of white blood cells. Because it strengthens cell regeneration and water retention, inhibits the formation of melanin and eliminates pigmentation; In addition, the rapid energy transfer and vibration of cells in each layer of skin will produce a certain range of reorganization, which will make the epidermis smooth and repair the fiber segments in the dermis; At the same time, it also densifies the fat, which can quickly increase the elasticity and luster of the skin, achieve the effect of beauty care, and truly glow. In addition, the expansion of capillaries can dredge the blockage of pores and effectively reduce or alleviate the occurrence of acne, acne and eczema. 7. Enhance immunity. Far infrared radiation feeds back the human body, making it feel warm, enhancing the immunity (resistance) and tissue regeneration ability of biological cells, accelerating the supply of nutrients and enzymes, and achieving the functions of health care and adjuvant therapy. 8. Far-infrared sauna can calm people's nerves, restore the function of self-regulation, inhibition or excitement of the central nervous system, and relieve the tension of the body. 9. Relieve fatigue, improve sleep, enjoy far-infrared sauna, gradually improve blood supply and oxygen supply to the brain, improve insomnia, relieve dizziness and headache, and eliminate brain fatigue to make people reach deep sleep. Disadvantages of steamer (1) Steam bath for male infertility is a fashionable and healthy leisure way. After sweating, the whole body is relaxed and exhausted, so many people who are nervous at work are good at it. However, medical experts warn that frequent contact with steamer may become the culprit of male infertility. In Finland, the birthplace of sauna, the incidence of male infertility is quite high, which is not unrelated to the local people's love for sauna. The temperature of testis is generally 3℃~4℃ lower than that of human body, so as to produce normal sperm. Sperm has strict requirements on temperature, which must be lower than body temperature to develop normally, while steaming temperature is much higher than body temperature, which is not conducive to sperm growth, or leads to excessive decline of sperm vitality and infertility. (2) The elderly should not sweat, because the elderly are physically weak. If they sweat too much, there will be electrolyte disorder, which will be life-threatening in severe cases. The above content is a detailed introduction to the advantages and disadvantages of the steamer. Friends who like steam bath can learn more about it. The biggest feature of the steamer is that it is portable, occupies little space, and can be steamed at home, reducing the trouble and cost of going out to the steamer. But the health function of prayer is the same as that of a steaming room, and it is the best means of personal and family health care. However, we should not only look at the advantages of the steamer, but also remember its disadvantages. Especially gay men, it is better to do less steaming.

What are the advantages and disadvantages of a house with a yard? What are the common structures?

In the past, China was sparsely populated, and almost every household had a yard, which was normal for many families. However, with the continuous growth of population, housing is becoming more and more tense, and there are fewer houses with yards, but there are still fewer places. So, what are the common structures of a house with a yard? What are the advantages of a house with a yard? What are the disadvantages? What is the housing demand? Now Bian Xiao will give you an answer. What are the common structures of a house with a yard? 1. All floors are paved with non-slip floor tiles or anticorrosive wood floors, covering all dirty floors, which are clean and tidy, easy to take care of, and do not attract mosquitoes. The function of this patio seems to be mainly to dry clothes and bedding and to "stock" children and dogs. 2. Build a circle of flower beds filled with soil around the fence for planting flowers, trees and vegetables, and lay non-slip floor tiles in other places, which avoids the disorganized feeling of gardening lovers getting a bunch of flower pots, but sacrifices the mobility and space utilization. Old people seem to like this design very much. 3. Dig a pond to raise water lilies and fish, set up a rockery in Taihu Lake, set up a stone table and bench, set up a grape trellis, and even set up a bamboo or wooden pavilion. The so-called pure Chinese courtyard is mainly fun, leaving little room for children to play and dry. 4. Only use cobblestones, floor tiles or even small stones to pave one or several roads, and all other areas are filled with bare soil, so as to plant plants with rich varieties, patchwork and open all the year round. This is a paradise for pure gardeners. 5. Dig a square "baby" swimming pool, lay anticorrosive wood floors, place umbrellas, recliners and waterproof sofas, so-called imitation American yard. What are the advantages of a house with a yard? The advantage of patio is obvious: 1. Large area; 2. The building spacing is large and the sunshine is good, so the lighting and ventilation in the house are also good, which is convenient for drying, and it is perfect for the elderly and children to bask in the sun; 3. There are few parabolic objects in the sky. I usually sweep the fallen leaves and pick up the clothes blown down from upstairs ... 4. There is still a lot of room for children to learn to walk and have fun. I also saw a miniature basketball stand with a slide in the yard ... 5. There is a lot of room for design, and all kinds of people can find their own interests. The disadvantage of a house with a yard is 1. Poor privacy. It's okay for the patio to face the greening, but it's more embarrassing for the road. Not without a solution. The property is not allowed to raise the fence. Didn't say not to plant. Plant a circle of trees with a height of one person along the fence (for example, in france holly, a treasure can buy saplings with a specified height) and prune them regularly. 2. Security concerns will be greater, and anti-theft devices or iron gates need to be installed. Because the fence is low, there will be some "visitors" in the courtyard, such as wild cats and mice. Above, Bian Xiao introduced some common house structures with yards. For your reference, if some houses have special needs, the advantages and disadvantages of the houses with yards introduced below are summarized and shared according to the personal experiences of some people who have lived, which also has certain reference significance for your choice. If consumers are not afraid of certain animals and have a budget, they can consider it. Because this kind of life is rich.
