With the development of economy and the gradual improvement of living standards, people have drunk enough "tasteless" boiled water, but they are looking for various ways to replenish water, such as "tea", especially for middle-aged and elderly people in their fifties and sixties. Drinking tea has become a must every day.
However, some people always prefer boiled water, so the question is, who is healthier and who often drinks boiled water or tea? Let's listen to the doctor.

The benefits of tea
Helps to inhibit cardiovascular diseases.
Tea polyphenols play an important role in human fat metabolism, such as cardiovascular diseases such as high cholesterol and triglyceride, such as fat deposition on the inner wall of blood vessels after proliferation of vascular smooth muscle cells and atherosclerotic plaques.
Tea polyphenols, especially catechins ECG and EGC in tea polyphenols and its oxidation products theaflavins, are helpful to inhibit this mottled proliferation, reduce the formation of fibrinogen that enhances coagulation viscosity, make coagulation clear, and thus inhibit atherosclerosis.
cancer prevention
Tea mainly fights cancer by resisting oxidation and scavenging free radicals, the products of human cell oxidation reaction.
As long as the human body keeps in contact with the outside world, such as breathing and pollution, it will constantly induce the production of free radicals, and the occurrence of tumors is related to the excessive production of free radicals.
Tea is rich in tea polyphenols, which has strong antioxidant and free radical scavenging effects. Therefore, drinking tea regularly can play a certain role in preventing cancer.
Detoxify
Tea has detoxification effect. In daily life, the human body will absorb all kinds of heavy metals and harmful substances. Excessive accumulation of these substances will cause damage to organs, and tea polyphenols in tea can adsorb and excrete these harmful substances.
In addition, people who smoke regularly can also drink more tea. Polyphenols in tea can precipitate nicotine and excrete nicotine with urine, thus reducing the harm of nicotine to the body.
Prevent premature senility
Many women want to look better or maintain their skin better, so they will go to beauty salons or use expensive skin care products for maintenance. In fact, drinking tea can also make you young.
Many studies have confirmed that tannic acid contained in tea is a powerful antioxidant, and its neutralization and oxidation ability is 18 times that of vitamin e, which can play an anti-aging role in human body.
The main cause of human aging is chromosome breakage, and tannic acid in tea can prevent chromosome breakage due to oxidation, thus achieving the purpose of delaying aging.

The benefits of drinking water
skin care
We often say, drink plenty of water, detoxify and maintain beauty, because drinking water can help the human body excrete urine, and excrete toxins in the body in this way, which can reduce pigmentation of skin spots and avoid edema.
Especially for people who especially like to stay up late, getting up early and drinking a cup of warm water is of great benefit to beauty.
Promote physical recovery.
When people catch a cold, or have a sore throat or cough, doctors always advise us to drink more water. In fact, there is some scientific reason for this. Drinking plenty of water is beneficial to expel toxins from the body, promote the excretion of harmful substances and relieve various discomfort symptoms.
Improve resistance
When the body is short of water, the body will have various symptoms, such as getting angry and catching a cold. Adequate water in the body not only helps to expel toxins, but also enhances immunity.
Water plays two key roles in human body: one is to participate in cell tissue, and the other is to participate in human metabolism.
Relieve fatigue
Modern people have the habit of going to bed late, but they have to get up early to go to work in the morning, which is prone to headaches, mostly because of dehydration caused by lack of water in the body or a lot of sweating, so if you can drink a cup of warm water at this time, you can get rid of headaches and be full of energy.
Especially in summer, due to the climate, it is easy to have listlessness and fatigue, which is also caused by physical deficiency, so drinking more water at this time can alleviate physical discomfort such as fatigue.

Through the above introduction, I believe everyone knows that whether drinking boiled water or drinking tea water, the body can get certain benefits, which is a very good way to replenish water. As for which is healthier, there is no specific answer.

Precautions for drinking water
It is not advisable to drink boiled water.
If the water is not boiled, the chlorine in the water will interact with the residual organic matter to produce a carcinogen called trihydroxy. If the pregnant mother drinks this water, it will not only be harmful to the body, but also have a bad influence on the baby.
Don't drink long-standing and reheated boiled water.
Nitrogen-containing organic matter in boiling water will be decomposed into nitrite which is harmful to human body. Nitrite can easily combine with hemoglobin in human body, thus hindering the normal oxygen transmission function of blood. Repeatedly boiled water will cause the rapid loss of beneficial minerals in the water.

Matters needing attention in drinking tea
Drinking tea is not greedy for novelty
From a nutritional point of view, the nutritional components of new tea (tea picked less than one month) are not the best.
Because these tea leaves have not been placed for a period of time, some substances that affect the body, such as polyphenols, alcohols, aldehydes, etc., have not been completely oxidized, and people may have diarrhea, bloating and other uncomfortable reactions after drinking.
Avoid drinking tea on an empty stomach.
Drinking tea on an empty stomach will dilute gastric juice, reduce digestive function, and also cause "tea drunkenness", which is characterized by palpitation, dizziness, headache, fatigue and instability. In addition, drinking tea on an empty stomach will aggravate hunger, and severe cases can cause hypoglycemia shock.
