Many middle-aged and older people are accustomed to drinking one or two liang (about 50–100 ml) of baijiu (Chinese liquor) with dinner, believing that the amount is small, that it promotes blood circulation and relaxes muscles and tendons, and even that it helps with sleep. This practice is widely circulated among the public, but from a medical perspective, drinking alcohol regularly every day, even in small amounts, places a continuous burden on the body. The World Health Organization has classified alcohol as a Group 1 carcinogen, and there is no "safe threshold" for alcohol intake.
How much alcohol is actually consumed with one or two liang of baijiu per day
Taking common 50-proof baijiu as an example, one liang is approximately 50 milliliters, containing about 20 grams of pure alcohol. This dose may seem small, but if consumed daily, the cumulative pure alcohol intake over a week exceeds 140 grams. The liver must continuously metabolize this alcohol, and the metabolite acetaldehyde is clearly toxic, directly damaging liver cells. In the long run, this "small amount" is actually not small at all; the body simply has not issued obvious warnings during the compensatory stage.
How long-term light drinking affects the liver and digestive system
The cumulative burden of liver metabolism
The liver is the core organ for alcohol metabolism. Drinking every day means liver cells have almost no window for repair and remain in a state of chronic overload. Even if only one liang is consumed daily, alcoholic fatty liver disease and elevated transaminase levels may develop after several years. As age increases, hepatic blood flow decreases and metabolic enzyme activity declines, so the same amount of alcohol causes greater damage.
Repeated irritation of the gastrointestinal mucosa
High-proof baijiu directly irritates the gastric mucosa. Daily drinking causes mucosal congestion and erosion, gradually progressing to chronic gastritis. Many people drink small amounts year-round and develop stomach pain, acid reflux, or heartburn in middle age; examinations reveal gastric mucosal atrophy or erosion, and only after reviewing lifestyle habits is the close link to long-term light drinking identified. This damage is progressive and is often overlooked in its early stages.
Chronic effects on the cardiovascular and nervous systems
Blood pressure fluctuations and vascular damage
After entering the body, alcohol first dilates blood vessels, then causes rebound constriction, leading to blood pressure fluctuations. Daily drinking subjects blood vessels to repeated pressure changes, accelerating the progression of atherosclerosis. For middle-aged and older people whose vascular elasticity has already declined, this stimulation increases the risk of hypertension, stroke, and myocardial infarction.
Disruption of sleep architecture
Many people mistakenly believe that a little alcohol helps them fall asleep. In reality, alcohol merely numbs the central nervous system, allowing people to enter light sleep quickly, but it suppresses deep sleep and rapid eye movement (REM) sleep. The result is frequent dreaming, easy awakening during the night, and dizziness and fatigue upon waking. Long-term reliance on alcohol as a sleep aid disrupts the circadian rhythm, worsens insomnia, and may even affect memory and emotional stability.
How hidden alcohol addiction forms step by step
When drinking at a fixed time every day, the brain gradually consolidates this behavior into a "required procedure." It begins as psychological anticipation and then develops into physiological tolerance and dependence. Once the body adapts to the stimulation of one liang of alcohol per day, the same dose no longer produces the same sense of relaxation, and people unconsciously increase the amount—from one liang to two liang, then three liang. Many people do not realize they have developed alcohol dependence until the day they want to stop but cannot. This process is often silent; the line between "a little drink for pleasure" and "feeling unwell without a drink" is far blurrier than imagined.
Why some people feel "drinking one liang a day keeps me in good health"
This mainly stems from two cognitive biases. First, the brief warmth and relaxation brought on by alcohol are misinterpreted as a "health-preserving effect," when in fact they are merely immediate reactions of vasodilation and neural inhibition. Second, the liver and blood vessels have strong compensatory capacity, so early damage produces no obvious symptoms; by the time fatigue, decreased appetite, elevated blood pressure, or other manifestations appear, organ damage may have already accumulated to a certain degree. The body not crying out in pain does not mean it has not been injured.
Health-preserving approaches that do not require alcohol
There are entirely safer ways to warm the body, relax, and improve sleep. Moderate exercise promotes blood circulation, regular routines and foot soaks help with falling asleep, and a light diet reduces the body's burden. These approaches do not produce alcohol's toxic metabolites and do not create dependence. True health preservation means reducing the body's extra burden, not using a Group 1 carcinogen to "invigorate blood circulation."
For those already accustomed to daily drinking, how to adjust scientifically
If a daily drinking habit has already formed, suddenly stopping completely is not recommended. Especially for long-term drinkers, abrupt cessation may trigger withdrawal reactions such as palpitations, sweating, irritability, and insomnia. A more prudent approach is gradual reduction—for example, cutting from one liang per day to half a liang, then lengthening the interval between drinks. If self-control is difficult or significant discomfort appears after reduction, the body may have already developed dependence, and professional evaluation and support are needed at that point.
Zhengzhou Beifang Alcohol Treatment Hospital is a member unit of the Zhengzhou People's Hospital medical consortium, specializing in the assessment and intervention of alcohol dependence. The hospital adopts an integrated approach of traditional Chinese and Western medicine, steadily controlling withdrawal discomfort while regulating the function of damaged organs such as the liver and gastrointestinal tract, helping long-term drinkers gradually reduce alcohol intake and rebuild a healthy rhythm. Learn more about the specific alcohol treatment path and plan, review safety precautions during the withdrawal period, or contact the hospital for professional advice.
