How to Beat Jet Lag: A Science-Backed Strategy

Jet lag isn't just tiredness — it's your circadian rhythm fighting against a new time zone. After dozens of long-haul flights, I've developed a system that minimizes recovery time from days to hours.

Before You Fly

Shift your schedule gradually. Three days before departure, move your bedtime 30 minutes earlier or later each day toward your destination time. Use the app Timeshifter — it creates a personalized plan based on your sleep pattern and flight details.

Fast before flying. A 16-hour fast before your destination's breakfast time helps reset your body clock. Eat your last meal at the appropriate time for your destination, then break the fast with a substantial breakfast after landing.

During the Flight

Control light exposure aggressively. If it's nighttime at your destination, wear an eye mask and avoid screens. If it's daytime, keep the window shade open and stay awake. Blue light blocking glasses help if you must use devices during "night" hours.

Time your melatonin carefully. Take 0.5-3mg of melatonin 30 minutes before your destination's bedtime — not your departure time. More is not better; higher doses can cause grogginess.

After Landing

Get outside immediately. Natural light is the strongest signal for resetting your circadian rhythm. A 30-minute walk in morning sunlight works better than any supplement.

Exercise lightly. A 20-minute jog or yoga session boosts alertness and helps your body adjust. Avoid intense workouts in the evening — they can delay sleep.

Eat on local time immediately. Even if you're not hungry, eat breakfast at local breakfast time. Your digestive system plays a major role in circadian rhythm regulation.
