Are you confused about whether you can shower after getting a flu shot, or when you can resume exercise or drink alcohol? You might also worry about whether pain at the injection site or a slight fever is a normal reaction or if you need to visit a doctor. The key is to avoid putting additional strain on your body immediately after vaccination and to monitor the severity and duration of symptoms. Short showers are permitted if you follow the conditions, and you should return to your daily routine as your body allows, while avoiding high-intensity exercise and drinking for at least 48 hours.

The causes can vary, ranging from hypersensitivity remaining in the airways to postnasal drip, cough-variant asthma, and gastroesophageal reflux. A post-infection cough can also manifest as a subacute cough lasting 3 to 8 weeks. However, since the response differs depending on whether the cough subsides over time or repeatedly worsens in specific situations, it is necessary to examine the progression of symptoms and accompanying signals together… Read more

For a humidifier, it is more important to adjust the humidity within the 40–60°C range according to the indoor temperature and season, rather than raising it too high.
