Moderate consumption of oolong tea can help refresh the mind and promote digestion, but excessive consumption may cause insomnia or gastrointestinal discomfort. Oolong tea contains components such as tea polyphenols and caffeine, and its benefits, risks, and intake are closely related. The caffeine in oolong tea can stimulate the central nervous system, help alleviate fatigue, and enhance attention. For people who need to concentrate on work or study, moderate consumption can improve efficiency. But drinking in the afternoon or evening may interfere with sleep quality. Tea polyphenols and catechins can accelerate fat breakdown and assist in regulating blood lipid levels. Long term regular intake can be helpful for weight management, but it needs to be combined with exercise to achieve significant results. The antioxidant components of oolong tea can help reduce low-density lipoprotein cholesterol and lower the risk of endothelial damage. Moderate consumption by middle-aged and elderly people may be beneficial for preventing arteriosclerosis. But drinking strong tea on an empty stomach may cause excessive secretion of stomach acid, leading to symptoms such as acid reflux and abdominal pain. Tannic acid can bind with non heme iron in food, reducing the absorption rate of iron elements. Anemic patients should avoid drinking tea immediately after meals.
It is recommended to drink no more than 800 milliliters of oolong tea per day and avoid consuming it 3 hours before bedtime. Choosing fragrant tea can reduce gastrointestinal irritation. Pregnant women, patients with arrhythmia, and patients with severe stomach diseases should consult a doctor before drinking.
