jet lag
Jet lag is a temporary condition that occurs when your body's internal clock, or circadian rhythm, becomes out of sync with a new time zone after rapid travel across multiple time zones. This disruption affects your sleep-wake cycle, causing symptoms like fatigue, difficulty sleeping, irritability, and difficulty concentrating. Your body naturally follows a 24-hour cycle based on daylight, but crossing time zones shifts this rhythm. Re-adjusting involves gradually syncing your internal clock with the local time through exposure to natural light, sleep timing, and other lifestyle adjustments.
