Question

My three-and-a-half-year-old son has an inner eyelid, and every time he has a cold and fever, one of his eyes will temporarily become double-lidded. Is there an inevitable connection between this change and the disease? Why does this happen every time?

Answer

This is a normal phenomenon. When people are tired or over-exhausted, the slightly creased single eyelid may temporarily become double-lidded. Similarly, people with double eyelids may also temporarily become triple-lidded when tired, sick, or sleep-deprived. Cold-induced dehydration not only causes changes in eyelids but also severely affects the normal metabolic function of the human body. Therefore, when feverish, it is important to replenish fluids by drinking plenty of plain water and fruit and vegetable juices, especially beetroot juice and carrot juice. During the cold, it is advisable to avoid solid foods until the condition improves.
