Tea is a traditional beverage of the Chinese nation.
green tea, yellow tea , white tea ... Different varieties of tea have different properties, tastes and tastes, and their effects on health are also different.
01
The season has changed, should we change the tea?
In fact, drinking tea should be different throughout the day, year, and life.
Among the six major teas in China, green tea is unfermented tea, white tea and yellow tea are lightly fermented tea, oolong tea is semi-fermented tea, black tea is fully fermented tea, and dark tea is post-fermented tea.
Green tea is the coolest, black tea is the warmest, white tea, yellow tea, oolong tea, and black tea are among them, and the temperature increases with the degree of fermentation.
When drinking tea in daily life, we can follow the above rules to choose:
During the day
Drinking a cup of stimulating green tea in the morning will make people more energetic. If you eat greasy in the evening, drinking a cup of black tea can assist metabolism. .
During the year,
drink green tea and white tea, which are more irritating and relatively cool in summer to relieve the heat; drink black tea and dark tea which are less irritating and relatively mild in winter to warm the stomach.
Throughout life
The quality of sleep is better when you are young. Drinking a cup of green tea with high caffeine content will not affect sleep; in old age, you often "doze off while sitting and cannot fall asleep when lying down". If you switch to microbial fermentation, Black tea with lower caffeine content will not affect your sleep much.
Of course, the above suggestions are not absolute, and personal tea drinking preferences and body differences need to be considered.

Several misunderstandings about drinking tea
Myth 1: Drinking tea can be unlimited
Drinking tea is beneficial, but drinking it improperly also has disadvantages.
If you drink too little tea, it will not be able to play a health care role. Drinking too much tea will increase the burden on the heart and kidneys, especially people with heart disease, high blood pressure, etc., should pay more attention.
Judging from the human body's water demand, combined with the medicinal ingredients and nutritional components of tea, generally speaking from the perspective of health care needs, a healthy adult should consume 6 to 15 grams of tea per day.
Use 3 to 5 grams of tea per cup, 2 to 3 cups a day. After brewing three times, the active ingredients have been basically leached, and the tea should be discarded.
Myth 2: Drinking tea can help you lose weight
Drinking tea can relieve fatigue and make people hungry faster. This is related to the caffeine, theophylline and other ingredients contained in tea.
These ingredients can stimulate gastric acid secretion, increase gastric motility, accelerate food digestion, and reduce the "greasy feeling" in the digestive tract. However, tea itself cannot consume calories, so it is not helpful for weight loss.
Moreover, Pu'er tea and black tea have a stronger effect on stimulating gastric acid secretion than green tea, so drinking Pu'er tea makes you more likely to get hungry.
Myth 3: Drinking tea can cause osteoporosis
There are many reasons for osteoporosis. The main influencing factors are intake and metabolism, which have little to do with drinking tea.
Although some components in tea, such as organic acids and polyphenols, can combine with calcium and affect their absorption, this effect is actually very small because the content of those components in tea is not high.
Therefore, drinking tea will not accelerate the formation of osteoporosis without any special disease.
Myth 4: You can’t drink tea after it’s cooled
You can drink tea after it’s cooled down, but relatively speaking, it’s better to drink warm tea.
Especially for unfermented green tea, its nature and flavor are yin. If it is taken cold, the three yins will be combined, which will easily damage the middle yang and cause abdominal pain and other discomforts.
Of course, it is not recommended that you drink tea that is too hot. According to research, people who often drink tea with a temperature exceeding 62°C are more likely to damage the stomach wall and are prone to stomach problems symptoms.
Therefore, after brewing the tea, it is best to wait for a while until the temperature of the tea cools down to below 60°C before enjoying it slowly.
Myth 5: Brewing a cup of tea can last you a day.
Many people know that you cannot drink overnight tea, but overnight tea does not have a strict definition. What needs to be paid more attention to is that it is tea that has been brewed for a long time.
Because the tea is brewed for too long, the tea polyphenols, lipids , aromatic substances, etc. in the tea are automatically oxidized. Not only is the tea soup dark in color, poor in taste, low in aroma, and loses its tasting value, but also due to the vitamin C in the tea. , vitamins P, amino acids , etc. are reduced due to oxidation, which greatly reduces the nutritional value of tea soup.
In addition, if the tea soup is left for too long, it will be contaminated by microorganisms, etc., which is not good for health, so it is best to brew it and drink it now.
Myth 6: Strong tea can relieve hangover
Many people think that tea can relieve hangover, but tea has a certain effect of stimulating the nerve center . For drunk people, drinking tea will increase the burden on the heart.
Especially some elderly people with poor heart and kidney function should pay special attention not to drink strong tea after drinking.
In addition, for some people who need to take sedative, sleep-aiding drugs and anti-arrhythmic drugs, it is not recommended to drink tea, because the theophylline and other ingredients contained in tea will reduce the efficacy of the drugs, which is detrimental to the control of the disease.
