Introduction
If there is no discomfort such as fever, headache, or fatigue after vaccination, and only mild soreness or swelling at the injection site, light exercises such as walking, yoga, or slow walking may be performed on the day of vaccination or the following day. These low-intensity activities do not increase physical strain and can promote blood circulation, without adversely affecting vaccine absorption or recovery.

Generally, if there are no discomforts after vaccination, light exercise is acceptable. However, if symptoms such as fever, fatigue, or local discomfort at the injection site occur, strenuous exercise should be avoided. If in doubt, it is advisable to consult a healthcare professional beforehand. Detailed explanations are as follows:

If there is no fever, headache, fatigue, or other discomfort after vaccination, and only mild soreness or swelling occurs at the injection site, light activities such as walking, yoga, or slow walking may be performed on the day of vaccination or the following day. These low-intensity exercises do not increase physical burden and can promote blood circulation, without negatively affecting vaccine absorption or recovery.

If systemic symptoms such as fever, dizziness, or nausea occur after vaccination, or if the injection site shows obvious redness, swelling, pain, or hard nodules, strenuous activities like running, jumping rope, or ball games should be temporarily avoided. At this time, the body needs to focus its energy on the immune response; strenuous exercise may worsen symptoms and potentially impair the immune response triggered by the vaccine. Exercise should only be gradually resumed after all symptoms have completely resolved.

Exercise after vaccination should be progressive, avoiding sudden increases in intensity. If palpitations, dizziness, or increased pain at the injection site occur during exercise, stop immediately and rest. Monitor your physical condition throughout, and contact medical personnel promptly if any abnormalities arise.
