Arpita Kohli, a psychologist at PSRI Hospital, explains that even mild dehydration can impair brain function and muscle performance while driving. This can lead to fatigue, slower reactions, and difficulty focusing – similar to the effects of alcohol. Signs of dehydration include dry mouth, thirst, headache, dizziness, and reduced alertness. Kohli advises staying hydrated before driving, especially on long trips or in hot weather. She warns that frequent dehydration may signal health issues like diabetes or kidney problems, requiring medical evaluation. (Updated 7 Oct 2025, 13:04 IST; source: link)
