Health & Body
Timing answers for your health, from everyday illnesses to recovery milestones. Find out how long colds, flu, and infections really last, when common medications like antibiotics or antidepressants start working, how long substances stay detectable in your system, and what realistic recovery timelines look like after surgery or injury. Every answer leads with the typical range, explains the factors that stretch or shorten it — age, severity, treatment, overall health — and flags the warning signs that mean it's time to see a doctor. Ranges reflect published guidance from sources like the CDC, Mayo Clinic, and Cleveland Clinic, not worst-case anecdotes.
