Since ancient times, tea has been considered a premium product for health preservation. According to scientific analysis, tea leaves contain protein, fats, over 10 vitamins, and nearly 300 components such as tea polyphenols, caffeine, and lipopolysaccharides, which can provide various health care and pharmacological benefits. Drinking two cups of tea daily can regulate the internal organs, purify the blood, activate blood vessels, combat aging, and detoxify the body. Moreover, during the cold and dry winter, a warm cup of tea not only helps ward off the chill but also nourishes and promotes overall well-being.

Drinking Tea in Winter Can Prevent Dryness

Winter is cold and dry, and many people experience itchy skin during this season. Drinking tea can help prevent winter itch because tea contains the trace element manganese, which protects human skin.

The protective effect of manganese on the skin is reflected in three aspects: First, manganese participates in many enzymatic reactions in the body, promotes protein metabolism, and helps excrete substances harmful to the skin, thereby reducing adverse skin stimulation. Second, manganese aids in the accumulation of vitamin B6 in the liver, enhancing the skin's anti-inflammatory function. Third, manganese can increase the activity of polysaccharide polymerases and galactosyltransferases, catalyzing the metabolism of certain vitamins in the body. All of these contribute to normal sebum metabolism and prevent skin dryness.

If people drink tea brewed from 4–6 grams of green tea daily, they can obtain one-third or more of the body's daily manganese requirement. This is undoubtedly very beneficial for protecting the skin and preventing dryness and itchiness.
