Science-Backed Strategies to Beat Jet Lag
Shift your circadian rhythm faster with our expert protocols on light exposure, fasting, and melatonin.
Understanding Your Circadian Rhythm
Jet lag is not just about being tired; it's a physiological mismatch between your internal body clock and the external environment. Your body clock is primarily regulated by two things: Light and Food.
The Light Exposure Protocol
Light suppresses melatonin.
- Traveling East: You need to advance your clock (sleep earlier, wake earlier). Seek intense morning light and strictly avoid light (wear sunglasses) in the late afternoon.
- Traveling West: You need to delay your clock (stay up later). Seek evening light and avoid early morning light.
The Fasting Trick
Your digestive system has its own peripheral clock. Some experts recommend the "Jet Lag Fast." Fast for 12-16 hours before you arrive in your new destination, and break your fast at the exact time of normal breakfast in your new time zone. This signals to your body that a new day has officially started.
Strategic Melatonin Use
Melatonin is not a sleeping pill; it's a darkness signaler. Taking a very small dose (0.5mg to 3mg) a few hours before your target bedtime in the new time zone can help trick your brain into thinking the sun has gone down, facilitating a faster shift.
