In the scorching summer, many people rely on tea to cool down and beat the heat. Additionally, drinking tea helps replenish the body's needed proteins and amino acids. According to relevant data, the polyphenols in tea (primarily catechin compounds) are beneficial for preventing and assisting in the treatment of various cancers, such as stomach and colon cancer.

It's important to note that while many know alcohol can intoxicate, few realize tea can too. Those who drink strong or excessive tea may experience symptoms like allergies, insomnia, trembling hands and feet, weakness, or nausea—this is known as 'tea drunkenness.' The culprit is caffeine, a stimulant in tea that, when consumed excessively, overstimulates the central nervous system. Therefore, summer tea drinking should follow these guidelines:

1. Not Too Much

Tea contains various vitamins and amino acids, aiding digestion, boosting mental alertness, and promoting diuresis. However, excessive tea can accumulate in the intestines, hindering diaphragm movement and absorption. It also increases heart strain due to rapid fluid intake. Generally, 1–2 cups a day is ideal.

2. Not Too Strong

Caffeine in strong tea can cause dizziness, headaches, hypersensitivity, nervousness, or even muscle tremors and irregular heartbeat—'tea drunkenness.' This is especially true for those with light diets or no tea-drinking habits.

3. Not on an Empty Stomach

Drinking tea on an empty stomach dilutes gastric acid, impairing digestion. Excessive tea leads to more sweating, further depleting salt and causing fatigue or dizziness.

4. Varies by Individual

People with conditions like neurasthenia, tuberculosis, heart disease, or ulcers, as well as pregnant or breastfeeding women and infants, should avoid tea. For tea drunkenness, eating snacks, sweets, or meals can help alleviate symptoms.

The above outlines key considerations for summer tea drinking. Always drink tea mindfully and follow these tips.
