Summary
Siim Land shares his biohacking toolkit for frequent travelers, covering practical strategies to beat jet lag, optimize sleep on the road, and maintain immune function while traveling. The conversation touches on light exposure timing, supplementation for circadian rhythm support, fasting protocols during travel, and how to keep up a fitness routine when your schedule and time zones are constantly shifting.
Key Points
- Shift your light exposure schedule 1-2 days before travel to pre-adapt your circadian clock to the destination time zone.
- Fasting during the flight and eating your first meal at the destination's normal mealtime accelerates circadian resetting.
- Melatonin (0.5-3mg) taken at the destination's bedtime for 2-3 nights helps lock in the new sleep schedule.
- Morning sunlight at your destination is the single most powerful jet lag reset tool.
- Blue-light-blocking glasses on the flight protect melatonin production when crossing time zones.
- Maintain immune function during travel with vitamin C, zinc, and adequate sleep -- airports and planes are high-pathogen environments.
Key Moments
Fasting during flights resets your circadian clock faster than melatonin alone
Siim Land explains that fasting during a flight suspends your metabolism and makes it receptive to the new time zone signal from your first meal, helping you adjust to jet lag faster than relying on melatonin alone.
"One of the best ways to actually help with jet lag in my opinion is this innovative fasting. So not eating because food has also like a really powerful effect on this is okay and clocks"
Start intermittent fasting by eliminating snacks, not skipping meals
Land advises newcomers to intermittent fasting to start by simply eliminating snacking rather than jumping into extended fasts, as even removing between-meal eating reduces blood sugar spikes and improves energy.
"if you're new to this, then yeah, just start off by like the first thing is probably just eliminate snacking."
Blue light at night shuts down melatonin and sleep quality
Land explains how artificial blue light from screens suppresses melatonin production at night, preventing the body from entering its natural repair processes even if you manage to fall asleep.
"the blue light, the artificial light that you get from your smartphone and the screens, you know, that's fine during daytime in moderation, but at night time, when you're about to go to sleep, then it does shut down a lot of these sleep hormones that your body produces or would produce naturally."
Sauna boosts immunity and reduces illness duration through heat shock proteins
Land describes Finnish research showing that regular sauna use activates heat shock proteins, inhibits viral replication, and significantly reduces both the frequency and duration of respiratory illness.
"regular habitual habitual use before getting sick has like a you're basically going to be less sick less often sick and your duration of the sickness is also going to be greatly reduced"
