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.

Ranges reflect published guidance from sources like the CDC, Mayo Clinic, and Cleveland Clinic, not worst-case anecdotes.
