Crying due to a cold is a symptom of a common viral infection. The symptoms of a common cold mainly include nasal and throat issues, such as dry mouth, sore and swollen throat, runny nose, tearfulness, and increased eye discharge.

Drinking plenty of warm water, taking vitamin C tablets, and using Levocetirizine Dihydrochloride Dispersible Tablets can help promote the repair of tissue mucosa and suppress gland secretion, effectively alleviating symptoms of tearfulness.
