Introduction
In general, excessive tea consumption may lead to sleep disturbances, impaired nutrient absorption, digestive discomfort, kidney dysfunction, and increased cardiovascular strain. It is recommended to drink tea in moderation to avoid unnecessary harm to the body. In daily life, moderate tea consumption is advised, with appropriate adjustments based on individual health status and drinking habits. Avoid excessive tea consumption before bedtime.
Generally, excessive tea consumption may lead to sleep disturbances, hinder nutrient absorption, cause digestive discomfort, impair kidney function, and increase cardiovascular strain. It is recommended to drink tea in moderation to avoid unnecessary harm to the body. A detailed analysis is as follows:
1. Sleep Disturbances
Tea contains caffeine, and excessive intake of caffeine may excessively stimulate the central nervous system, thereby affecting sleep quality and potentially causing insomnia or worsening existing sleep disorders.
2. Hindered Nutrient Absorption
Excessive intake of tea polyphenols contained in tea may interfere with the body's absorption of minerals such as iron and calcium, which may lead to malnutrition, iron-deficiency anemia, and other symptoms.
3. Digestive Discomfort
Although moderate tea consumption can aid digestion, excessive intake may overstimulate gastric acid secretion, leading to symptoms such as stomach pain, bloating, and acid reflux. Long-term excessive tea consumption may increase the risk of digestive system diseases such as gastritis and gastric ulcers.
4. Kidney Function Impairment
Tea contains a high level of oxalic acid. Excessive consumption may lead to the formation of calcium oxalate crystals when oxalic acid combines with calcium in the body. These crystals may deposit in the kidneys, leading to kidney stones and impairing kidney function.
5. Increased Cardiovascular Burden
Excessive intake of stimulatory substances such as caffeine in tea may accelerate heart rate and elevate blood pressure. For individuals with existing cardiovascular conditions such as hypertension or heart disease, this may worsen their condition or trigger acute events.
In daily life, it is recommended to consume tea in moderation and adjust intake according to individual health status and tea-drinking habits. Avoid excessive tea consumption before bedtime to prevent disturbances in sleep quality.
