After suffering from heatstroke, due to the weakened immune system and internal environmental disorders, one is prone to catching a cold. The common symptoms of a cold include sore throat, fever, generalized weakness, nasal congestion, runny nose, and cough. There might also be complications such as electrolyte imbalances and symptoms of dehydration. Therefore, if one develops the aforementioned cold symptoms after experiencing heatstroke, it is crucial to increase fluid intake, get adequate rest, and possibly visit a hospital for routine blood tests and other relevant examinations to determine whether there is an electrolyte imbalance while dehydrated, and to actively seek appropriate treatment.
