The Impact of Tea and Coffee on Sexual Function
The Impact of Tea and Coffee on Sexual Function
Tea is the most widely consumed beverage worldwide, both historically and today. It contains various alkaloids such as caffeine and theophylline, which, when absorbed by the body, have a clear stimulating effect on the central nervous system. This helps eliminate fatigue, invigorate the mind, and improve sensitivity and responsiveness to sexual stimuli. Therefore, moderate tea consumption can enhance and improve libido, benefiting sexual function.
However, since many people engage in sexual activity shortly before bedtime, drinking tea at night may increase nervous system excitability, potentially causing insomnia. Thus, it is not recommended to drink strong tea at night to boost sexual arousal, as this could disrupt sleep.
Tea has both positive and negative effects on sexual function. According to Traditional Chinese Medicine, excessive consumption of strong tea can lead to over-diuresis, damaging the kidneys. Impaired kidney qi then leads to reduced sexual capacity. Additionally, due to tea’s bitter and cold nature, individuals with deficient kidney yang should avoid drinking too much.
Coffee has quietly entered the homes of ordinary Chinese families in recent years as a foreign beverage. It acts as a stimulant, enhancing one’s perception of external stimuli or self-awareness to some extent. After consuming coffee, sensations during sexual activity are often more vivid and intense. Its stimulating properties increase sexual excitement, elevate libido, shorten the time to orgasm, and its effect is more pronounced in women than men. Some overseas studies suggest that drinking one cup of coffee daily can enhance libido and improve sexual function.
Nevertheless, coffee is a stimulant, and excessive intake offers no health benefits. It may keep the body in a state of excitement after sex, hindering physical and mental recovery. Recent studies abroad have found that high doses of coffee possess mutagenic potential. Experts therefore caution against long-term or excessive coffee consumption—moderation is best.
