Tea has a long history of medicinal use, and in general, its effects on the kidneys are positive. However, as with most things, moderation is key. Improper tea consumption can negatively impact health. While tea is often believed to support kidney health, incorrect drinking habits can harm the kidneys instead. If you engage in any of the following practices, it is advisable to avoid them to protect your health......

1. Drinking tea while consuming alcohol harms the kidneys.

Some believe that strong tea can "sober up" after drinking, but this is a misconception. Drinking tea alone does not harm the kidneys, but combining it with alcohol or using strong tea as a remedy for intoxication can damage them.

Alcohol is broken down in the liver into water and carbon dioxide, which are excreted by the kidneys. Theophylline in tea has a diuretic effect, causing undecomposed acetaldehyde (a byproduct of alcohol metabolism) to enter the kidneys prematurely. Acetaldehyde is highly damaging to kidney tissues.

2. Excessive tea consumption harms the kidneys.

Tea contains fluoride, and excessive intake can damage the kidneys. The kidneys are the primary organs responsible for fluoride excretion. When fluoride intake exceeds the kidneys' capacity, it accumulates in the body, particularly in the kidneys. Studies show that excessive fluoride retention can damage renal tubules in the cortex and medulla.

3. Drinking tea on an empty stomach harms the kidneys.

Some people habitually drink tea first thing in the morning on an empty stomach. However, tea contains caffeine, which stimulates the body, accelerates heart rate, and increases kidney workload by promoting frequent urination. In severe cases, this can impair kidney function. To avoid harm, drink water before consuming tea.

4. Drinking overly strong tea harms the kidneys.

Tea is rich in oxalic acid, and excessive consumption can lead to hyperoxaluria, increasing the risk of calcium oxalate kidney stones. Additionally, strong tea forces the kidneys to work harder, potentially causing damage. Therefore, drinking mild tea is healthier for the body.

As the saying goes, "Rome wasn't built in a day." Neglecting small details can lead to significant harm over time. To safeguard your health, avoid these tea-drinking mistakes and cultivate better habits.
