It is not recommended to have sex during a cold because the majority of people have discomfort during a cold, lightly including sneezing, runny nose or sore throat, and if only these discomforts are present, sex will not aggravate the symptoms and the cold will not appear to worsen. However, cold may also have general discomfort symptoms, such as repeated fever, weakness, obvious fatigue and lack of energy, when having sex may not only aggravate the symptoms, but also the feeling of sex will be more affected, so it is not recommended to have sex. Some other more specific colds are likely to lead to complications, such as liver inflammation or even myocarditis, which cannot be detected without the relevant blood tests, and if you do more strenuous activities, physical exercise will aggravate the original inflammation. Therefore, it is not recommended to have sex during the cold, but to wait until the symptoms have completely disappeared and then have sex with confidence.
