1. Refresh your mind
In daily life, often due to work pressure, do not get enough sleep, during the day will also be sleepy, at this time you can drink tea to refresh. Tea contains caffeine, which can promote the excitement of the central nervous system of the human body and increase the activity of the cerebral cortex, thus playing a refreshing role.

When eating too much greasy food and feeling uncomfortable in the stomach, drinking a few cups of tea can quickly and effectively relieve greasiness and relieve greasiness.
3. Clear the heat and relieve the heat
The high temperature of summer makes people feel irritable, prone to thirst and heat stroke. Tea can just clear the heat to cool off, polyphenols, amino acids and other substances will stimulate saliva secretion, so that the mouth remains moist, and accompanied by a sense of coolness, so that people calm down.
4. Inhibit cardiovascular disease
Cardiovascular and cerebrovascular diseases are a major disease that threatens people's physical health, with a high prevalence rate and a dangerous seizure. The tea polyphenols in tea have an important role in fat metabolism, and reducing fat can effectively reduce the incidence of cardiovascular diseases such as hyperlipidemia. It can also inhibit plaque hyperplasia, reduce coagulation viscosity, and inhibit atherosclerosis.
5. Prevention of Alzheimer's disease
In the study, people who drank tea regularly had a 50 percent lower risk of cognitive decline than those who drank less tea. Tea is rich in vitamin C and vitamin E, which have antioxidant properties that can delay aging and enhance physical fitness. Tea polyphenols can also effectively scavenge free radicals, making the body more youthful.

Various studies have proved that drinking tea is good for the human body, especially the tea polyphenols in tea, which have many functions and have a preventive effect on many diseases. It is not surprising that more and more young people are now joining the ranks of health care.
Second, pay attention to the 2-point tea drinking method
There are also rumors that drinking tea will have certain disadvantages, and even cause cancer. This makes people wonder, in the experimental study found that tea can effectively reduce the incidence of cancer, how can it cause cancer? In fact, there is no need to worry too much, drinking tea must be more beneficial than harmful to the human body, as long as you pay attention to the following two points, it will not increase the risk of cancer.
1. Drink hot tea
The Jiangsu and Zhejiang areas are high incidence areas of esophageal cancer, and research has found that people in this area prefer to drink hot tea. That is to say, esophageal cancer and drinking hot tea have a certain relationship, drinking hot tea is harmful to the human body.
When the temperature of the tea exceeds 60 degrees, it is considered a hot drink, and the excessively hot water temperature is easy to burn the esophagus and repeatedly stimulate the esophagus. When the esophagus is burned, the body repairs itself, replicating DNA in large quantities. When the number of replications increases, the probability of error also increases, which in turn increases the risk of genetic mutations, that is, the risk of cancer increases.
The oral mucosa and esophageal mucosa are very fragile, and too high a temperature can cause them to be injured. In order to avoid the damage caused to the body by this way of drinking tea, do not rush to drink after brewing tea, and reduce the water temperature to less than 60 degrees, which can not only benefit the health of the body, but also make the taste of the tea better and more mellow.
2. Drink strong tea
Tea is rich in nutrients that are beneficial to the human body, but it is not that the stronger the drink, the better, and drinking strong tea or drinking too much tea will cause great harm to the body. Strong tea will stimulate the stomach and intestines, affect digestion and absorption, and also affect the body's absorption of iron, which can easily lead to anemia. Excessive caffeine is also prone to osteoporosis and is even less friendly to the elderly.
The appropriate amount of caffeine in tea can refresh the mind and help people learn to work better, but excessive caffeine stimulation will put the central nervous system in a state of excitement, slowly produce tolerance, causing insomnia and irritability. It also stimulates the cardiovascular system and sympathetic nervous system, resulting in symptoms such as arrhythmias, rapid heartbeat, and chest tightness. The presence of caffeine stimulates the mucosa of the digestive tract, which may lead to mucosal lesions and cause stomach cancer and esophageal cancer.
Therefore, drinking tea is still based on light, do not drink strong tea, hot tea, and do not drink too much tea in one day. Normal drinking tea will not cause harm to the body, and the incorrect way of drinking tea is the cause of cancer risk in the body.
3. Other matters needing attention
In addition to the above two bad ways of drinking tea will affect the health of the body, there are some places to pay attention to, which may also have adverse effects on the body.
1. Do not drink tea when you have a fever
Tea contains caffeine, which stimulates nerves and accelerates blood circulation. When the body temperature rises when the fever is high, the heat cannot be dissipated, and it is already urgent to dissipate heat. The tannic acid contained in tea has an astringent effect, which will affect the heat dissipation of the human body, under normal circumstances, there is no big problem, once the fever, the consequences will be serious.
2, do not drink tea while smoking
The caffeine in tea and the nicotine in cigarettes can cause irritation to the stomach. If you drink tea while smoking, it will cause double irritation to the stomach, damage the gastric mucosa, and increase the risk of cancer.
3. Clean the tea set in time
Many cups that have been used for a long time will appear tea scale and appear brown. This is due to the minerals and trace amounts of harmful heavy metal ions in the air, such as cadmium, mercury, etc. When heating, with the increase of temperature, there will be some substance precipitation, these substances will enter the tea cup with water brewing tea, tea is exposed to the air, and the tea polyphenols in the tea leaves will react with these substances, which will produce tea scale.
These tea scales are brown tea rust containing cadmium, over and other harmful metals, endangering human health. Therefore, after drinking tea, we must clean the utensils in time to avoid long-term placement leading to harmful substances in the cup to harm themselves. If you have found that there is a residual brown substance in the cup, the old dirt can not be washed clean, it is best to change a clean utensils to drink tea to ensure that there will be no harmful substances.
Fourth, drinking tea is addictive
People who like to drink tea will not only drink tea when they are alone, but also make tea when there are guests to entertain, and over time, it will become uncomfortable not to drink tea for a day, just like coffee, tobacco and alcohol, there is a situation of drinking tea addiction. People with tea addiction often need to drink tea every day to refresh their minds, if they do not drink, they will feel that they have no energy all day and cannot lift their energy. So how does tea addiction form? Do you want to quit?
1. Caffeine
Caffeine in tea is the culprit of tea addiction, and long-term consumption of caffeine-containing foods will make people addicted. Caffeine suppresses the adenosine receptors, and the lack of adenosine receptors will increase the nervous system thinking that the body needs more adenosine receptors. Adenosine promotes the conduction of neurotransmitters, and once caffeine-containing foods are suspended, the body expects adenosine and becomes addicted to caffeine.
2. Dopamine
Dopamine is a brain endocrine substance responsible for the brain's emotions and feelings, transmitting information such as pleasure, and is a factor that affects human emotions. Tea also contains amino acids, which stimulate the brain to secrete dopamine, produce a sense of pleasure, and make people excited and active. The human body will have a pleasant feeling of wanting to have more dopamine, and it will also expect to drink tea to achieve its goal.
3. The aroma of tea leaves
The tea itself has a unique fragrance, delicate and elegant, so that tea tasters have a sense of pleasure. The fragrant substances of tea are different from industrial processed products, and the pure natural aroma will soothe people's mood and calm down. When drinking tea, some people will pay more attention to the aroma of tea leaves, smelling a unique fragrance that is unforgettable.
4, too much stimulation
The taste of strong tea is even more fascinating and addictive, and it is said that it is easy to fade from thick to light, and it is difficult to go from thick to light. The stronger the tea, the more irritating it is, the more sensitive the human body's taste buds and nerves are, which is difficult to forget. Tea addiction is actually a common phenomenon, and there is no need to worry more, but also to go with the flow and maintain an optimistic attitude.
Tea is one of the three major health drinks in the world, which is conducive to human health, but tea drinking is the need to master, according to the physical situation to choose the right tea varieties, the thickness is suitable, the temperature is appropriate, enjoy the fun of drinking tea. If there is a great tea addiction, it is also not possible, excessive tea drinking will still damage the health of the body, serious and even life-threatening.
Fifth, the harm of excessive tea drinking
1. Overexcited brain
People with large tea addictions drink a lot of tea every day, and the substances in the tea leaves make the brain overexcited. Once you do not drink tea and do not consume caffeine, amino acids and other substances, you will have difficulty concentrating and do not have enough energy to work and live. Drinking tea in large quantities leads to insomnia, and during the day there is no spirit, and can only rely on drinking tea to refresh the mind, a vicious circle, making the tea addiction even greater. In the long run, the body's energy loss is huge, endangering health.
2. The spleen and stomach are overburdened
In addition to the brain will be overexcited to consume energy accidents, the spleen and stomach will also receive great damage. Excessive stimulation makes the spleen and stomach overburdened, and after a long time, it will induce indigestion and even affect the detoxification function.
The harm of excessive tea drinking is not small, and it must not be taken lightly. When you find that you have a certain addiction to tea, you can consciously control your intake of tea, rather than allowing yourself to drink more and more every day. You can slowly reduce the frequency and amount of tea drinking, control it little by little, and don't let yourself become more and more addictive.
summary
Tea culture is our unique Chinese culture, passed down to today, many people have forgotten its unique charm, just to reflect their own taste of rude tea drinking, do not understand its essence. Drinking tea has many benefits for the human body, can effectively prevent various diseases, can be used in daily life to refresh the mind, improve work efficiency, calmly face life, enhance happiness.
But the incorrect way of drinking tea will be counterproductive, but it will increase the chance of cancer. I hope that more and more people can drink tea and taste tea, and I hope that more people can understand tea, understand its advantages and disadvantages to the human body, pay attention to it at all times in daily life, and do not do things that are harmful to the body.
