But he always felt tasteless in his mouth recently, and he was always forgetful, so he made an appointment with Uncle Li to go fishing, but he couldn't remember anything!
Uncle Li waited for a day and saw no one, and when he came back in the evening and saw Master Gao's state, he persuaded him: "Master Gao, your face is much worse than before, why don't you remember things in your head?" You are just 49 years old this year, so let's go to the hospital for a check-up." ”
Master Gao didn't think he had forgotten to go to the appointment? He didn't have to curse himself for Alzheimer's disease. So I ignored Uncle Li's suggestion.
But then the symptoms became more and more serious, and Master Gao didn't even remember to go to the toilet! The children realized that something was wrong and quickly sent their father to the hospital for examination, and the results showed that Alzheimer's disease. The doctor said that it may be related to Master Gao's excessive tea drinking.
1. Don't be careless, frequent tea drinking may bring 4 major harms to the body!
Drinking tea is a health preservation technique in the hearts of many people in life, because tea contains tea polyphenols and other substances, and developing the habit of drinking tea can even promote metabolism, help the body detoxify, and even prevent cardiovascular diseases.
However, Wang Juan, attending physician of the Department of Medical Imaging of Tengzhou Central People's Hospital, said that drinking tea will cause harm to some specific groups of people, such as patients with iron deficiency, drinking tea will aggravate the symptoms of anemia, for insomniacs with mental weakness, drinking tea will deepen the symptoms of mental fragility, and for patients with imperfect liver function, the ingredients in tea will prevent the normal play of metabolic function and even increase the burden on the liver.
Therefore, we need to make it clear that not all groups of people are suitable for drinking tea. Moreover, drinking tea also has many hidden dangers to our body, for example, after drinking tea, the blood pressure of some people will fluctuate, because the caffeine and theophylline in tea will stimulate the central nervous system, so that the heart contractility is enhanced, thus causing a temporary increase in blood pressure.
Sometimes, it can also cause insomnia, because tea contains substances such as caffeine, which can stimulate the central nervous system and keep people awake, thus affecting the quality of sleep. It is manifested as difficulty falling asleep, waking up easily or early, and long-term insomnia may lead to problems such as daytime fatigue and difficulty concentrating.
It can even cause anemia because the tannic acid in tea can hinder the absorption of iron, and drinking strong tea may cause hemorrhagic anemia. Patients may have symptoms such as dizziness and fatigue, and in severe cases, they may have paleness and difficulty breathing.
When the condition is severe, it can even cause palpitations in people with pre-existing cardiovascular diseases, because excessive tea consumption will cause sympathetic nerve excitement, make the heart beat faster, and produce a feeling of palpitations.
Second, these 4 types of people must be cautious when drinking tea
Tea is an indispensable part of many people's daily life, and a cup of fragrant tea can refresh the mind, relieve fatigue and get rid of boredom. However, for some groups of people, drinking tea may not be an ideal option. For example, people with stomach ulcers who drink too much tea can cause stomach upset and even aggravate the condition. Who else is not suitable for tea?
1. Children
Since children's physical development is not yet mature, the caffeine in tea may affect the central nervous system, leading to problems such as insomnia, difficulty concentrating, etc. If children drink a lot of tea for a long time, they may develop health problems such as malnutrition and anemia. In addition, excessive caffeine intake may also cause symptoms such as increased heart rate and increased blood pressure.
2. Pregnant women
Hormone levels in pregnant women vary greatly, and drinking tea at this time may affect the growth and development of the fetus and even increase the risk of miscarriage. For example, pregnant women drinking excessively strong tea will cause rapid heartbeat and increased blood circulation, which can cause symptoms such as heart palpitations and chest tightness.
3. Menopausal women
Menopausal women have endocrine disorders and are prone to mood swings such as irritability, anxiety and depression. Tea contains a certain amount of caffeine, which can enhance the excitability of the central nervous system and aggravate the above uncomfortable symptoms.
4. Patients with epilepsy
Tea contains theophylline, which can irritate the gastric mucosa and irritate the ulcer surface, thus aggravating the condition. For people with ulcer disease, drinking tea may exacerbate symptoms such as stomach pain, nausea and vomiting.
3. Drink tea correctly, or reap the 3 major benefits
Tea, as one of the world's top three beverages, is an indispensable part of many people's daily lives, along with coffee and cocoa. Not only does it provide a pleasant mouthfeel, but it also has a number of unexpected benefits.
First of all, drinking tea can help digestion, because tea contains tea polyphenols and other substances, which can stimulate the secretion of gastric juice and promote gastrointestinal peristalsis, thereby improving the efficiency of digestion and absorption. In addition, the catechins in tea also have antibacterial and anti-inflammatory effects, which can effectively inhibit the growth and reproduction of harmful bacteria in the intestine and maintain the balance and stability of the intestinal microecological environment.
Moreover, the tea polyphenols in tea have antioxidant effects, and since oxidative stress plays a key role in the development of Alzheimer's disease, increasing antioxidants in the body can reduce the risk of Alzheimer's disease. Tea polyphenols act as a natural antioxidant that scavenges free radicals and reduces cell damage, thereby slowing down the aging process of the brain.
