Cardiovascular diseases are one of the top three killers threatening human health in modern times. Excessive diet, lack of exercise, and environmental pollution are all external causes of cardiovascular diseases such as hypertension, hyperlipidemia, high blood sugar, and atherosclerosis.

Hypertension

Hypertension is a common disease among modern people, especially urban residents. Due to adverse external and internal stimuli disrupting the excitation and inhibition processes of the cerebral cortex, abnormal angiotensin production occurs in the liver. Inactive angiotensin I is converted into active angiotensin II under the action of a converting enzyme, leading to increased blood pressure.

Dark Tea to the Rescue: The catechin compounds and theaflavins in dark tea have a significant inhibitory effect on the activity of angiotensin I-converting enzyme. The caffeine and catechins in tea can relax blood vessel walls, increase their effective diameter, and lower blood pressure through vasodilation. The flavonoids in tea help maintain normal capillary resistance and enhance the toughness of blood vessel walls. Therefore, regularly drinking dark tea can help lower blood pressure while maintaining vascular elasticity, eliminating vascular spasms, and preventing blood vessel rupture.

Hyperlipidemia

Hyperlipidemia refers to cholesterol and triglyceride levels in the blood being higher than normal. It can easily lead to cerebral hemorrhage, coronary heart disease, atherosclerosis, thrombosis, and obesity.

Dark Tea to the Rescue: The tea polysaccharides in dark tea can reduce serum low-density lipoprotein (LDL) cholesterol, which is responsible for depositing cholesterol into blood vessels and causing atherosclerosis. Tea polysaccharides can also bind with lipoprotein lipase, promoting its entry into the blood from arterial walls, thereby exerting an anti-atherosclerotic effect.

Respiratory Diseases

Heavy fog and very low visibility weather can affect human health. The main危害 to human health comes from aerosol particles with a diameter of less than 10 micrometers, which can directly enter and adhere to the upper and lower respiratory tract and lungs, causing conditions such as rhinitis and bronchitis. Long-term exposure to such an environment can also induce lung cancer.

Studies have shown that when air pollution worsens, the mortality rate of cardiovascular patients increases. Particulate pollutants in hazy weather can not only trigger myocardial infarction but also cause myocardial ischemia or damage.

Dark Tea to the Rescue: The tea polyphenols in dark tea can not only precipitate submicron particles (PM2.5) inhaled into the lungs and excrete them through urine but also清除 free radicals in the human body, reducing the toxic effects of smog. For heavy metal toxins, tea polyphenols have a strong adsorption effect. Therefore, drinking more golden flower dark tea can also alleviate heavy metal poisoning. In addition, the "golden flower" in dark tea is a natural, healthy, and side-effect-free antibacterial king that can kill most bacteria and viruses.

Summary:

Regular consumption of dark tea can improve blood circulation, enhance oxygen transport capacity, and has excellent effects on cardiovascular diseases. Modern scientific research proves that dark tea contains rich substances.
