About Jet Lag
Jet lag occurs when your internal body clock (circadian rhythm) is out of sync with the local time at your destination. Symptoms include fatigue, insomnia, difficulty concentrating, digestive issues, and mood changes. The general rule is that it takes about 1 day to recover for every 1.5 hours of time zone change. Light exposure is the most powerful tool for resetting your circadian rhythm.
