Alcohol contained in red wine is harmful to the body. Excessive drinking will increase various health risks, such as liver damage, gastrointestinal irritation, vision and nervous system.
Therefore, it is necessary to control the daily intake. Drinking red wine in moderation is beneficial to health, and it is generally recommended to drink 80ml~ 100ml every day.
If the amount of red wine you drink every day exceeds this range, it will be harmful to your health, especially if you drink half a bottle of red wine every day for a long time, the harm will increase with time.
In a word, whether drinking half a bottle of red wine every day is harmful to your health needs to consider personal health, drinking habits, alcohol intake and other factors. If you feel unwell, you should seek medical advice promptly.
