The benefits of drinking Tea

Drinking tea has many benefits, mainly including the following aspects:
1、 In terms of physical health

1. * * Antioxidant effect**
   -Tea contains abundant tea polyphenols, which are natural antioxidants. Tea polyphenols can eliminate free radicals in the body, which are harmful substances produced during human metabolism. They can attack cells, causing cell damage and leading to various diseases such as cancer and cardiovascular disease. For example, catechins are one of the main components of tea polyphenols, and their antioxidant capacity is stronger than that of vitamin C and vitamin E. Drinking tea regularly can help the body resist the invasion of free radicals and slow down the rate of cellular aging.
2. * * Cardiovascular Health**
   -Helps to lower cholesterol. The components in tea can inhibit the absorption of cholesterol in the intestine, reduce the level of low-density lipoprotein cholesterol (LDL-C, commonly known as “bad cholesterol”) in the blood, and increase the level of high-density lipoprotein cholesterol (HDL-C, “good cholesterol”). For example, oolong tea has a certain role in regulating blood lipids, and long-term drinking has positive significance in preventing atherosclerosis and other cardiovascular diseases.
   -Adjust blood pressure. Some teas have a certain vasodilatory effect, which helps to lower blood pressure. For example, some components in green tea can promote the release of nitric oxide from vascular endothelial cells. Nitric oxide can relax vascular smooth muscle, reduce peripheral vascular resistance, and assist in lowering blood pressure. However, for hypertensive patients who are already taking antihypertensive drugs, drinking tea cannot replace medication treatment.
   -Reduce blood viscosity. Tea can inhibit platelet aggregation and reduce the risk of thrombosis. Excessive blood viscosity can easily lead to thrombosis, causing cardiovascular and cerebrovascular accidents such as myocardial infarction and cerebral infarction.
3. * * Preventing cancer**
   -Although it cannot be said that drinking tea can completely prevent cancer, many studies have shown that the components in tea may have a certain preventive effect on certain cancers. For example, some components in tea polyphenols can induce cancer cell apoptosis, prevent cancer cell proliferation and metastasis. For digestive tract cancers such as gastric cancer, colon cancer, etc., the preventive effect of tea may be related to its detoxification of carcinogens in the gastrointestinal tract. Meanwhile, the components in tea can also regulate the human immune system, enhance the body’s ability to recognize and eliminate cancer cells.
4. * * Helps with digestion**
   -The caffeine and tea polyphenols in tea can stimulate gastric juice secretion and promote gastrointestinal motility. For example, drinking a cup of tea after a meal can help digest food and relieve greasiness. For people with indigestion and loss of appetite, drinking tea in moderation can improve digestive function. Different types of tea have varying degrees of digestive assistance. For example, Pu erh tea, after fermentation, contains more microorganisms and enzymes, which have a good effect on improving gut microbiota and promoting food digestion and decomposition.
5. * * Control weight**
   -The caffeine in tea can increase the body’s metabolic rate, allowing the body to consume more energy during rest. Meanwhile, tea can reduce fat absorption and promote fat breakdown. For example, some studies have found that the components in green tea may activate enzymes related to fat breakdown, accelerating fat metabolism. Long term adherence to drinking tea, combined with a reasonable diet and exercise, has a certain auxiliary effect on weight control.
6. * * Enhance immunity**
   -The components in tea can regulate the function of the human immune system. For example, amino acids, polysaccharides, and other components in tea can enhance the activity of immune cells and improve the body’s resistance. Especially during seasonal changes and when it’s easy to catch a cold, drinking tea appropriately can help the body better resist the invasion of viruses and bacteria.
7. * * Protecting teeth**
   -The fluoride element in tea can enhance the acid resistance of teeth and prevent dental caries. Fluoride ions can combine with hydroxyapatite in teeth to form more insoluble hydroxyapatite, thereby improving the hardness and anti caries ability of teeth. Meanwhile, tea polyphenols and other ingredients can also inhibit the growth of bacteria in the oral cavity and reduce the formation of dental plaque.
   2、 In terms of mental health
8. * * Refreshing and refreshing**
   -The caffeine in tea is a central nervous system stimulant. When a person feels tired or sleepy, drinking a cup of tea can stimulate the cerebral cortex, increase the excitability of the nervous system, and make people more alert and focused. For example, drinking a cup of tea during work or study can help improve work efficiency and learning outcomes. However, excessive intake of caffeine may lead to problems such as insomnia, so it is important to pay attention to the timing and amount of tea consumption.
9. * * Relieve stress**
   -The process of drinking tea itself is a ritual of relaxing the body and mind. During the process of brewing tea and tea, people can temporarily put aside the pressure and troubles in life and focus on their current feelings. Moreover, some components in tea, such as theanine, have a certain sedative effect. Theanine can regulate neurotransmitters in the brain, produce a sense of relaxation, and alleviate anxiety and tension.
