You can drink room-temperature beverages after vaccination, but you should avoid consuming too many sweet and stimulating beverages and cold drinks to avoid certain stimulation of the gastrointestinal tract, which may easily cause symptoms such as abdominal pain, diarrhea and enteritis, which may be confused with adverse reactions to vaccination and be detrimental to doctors’ diagnosis. After vaccination, some people may have adverse reactions to vaccination, such as weakness, fever, diarrhea, abdominal pain, nausea, vomiting and other adverse reactions. At this time, it is recommended to drink more warm water to promote the body’s metabolism. Avoid cold drinks, coffee, tea and various kinds of alcohol in your diet. Coffee and tea are refreshing and not conducive to sleep and can affect the immune function of the body; drinking alcohol may cause reactions such as rapid heartbeat, nausea and vomiting; drinking cold drinks may cause discomfort such as diarrhea and abdominal pain, all of which may be confused with or aggravate the adverse reactions produced by vaccination. Therefore, after vaccination, it is recommended that you should pay attention to a light and easily digestible diet, drink as much warm water as possible, eat less spicy and stimulating food, carbonated drinks, etc., and avoid foods that easily cause allergies, such as seafood. In life, you should take proper rest and sleep, avoid strenuous exercise for 7 days, pay attention to keeping the injection site dry and hygienic, and avoid bathing for 24 hours to avoid infection.
