It can keep you up at night, make you feel exhausted at strange hours of the day, hungrier or less hungry, and cause irritability because your circadian rhythm is out of whack.
Your circadian rhythm is your 24-hour body clock. You get used to doing certain things within a 24-hour period that tells you when you’re tired, alert, hungry and so on. Travelling through time zones upsets this rhythm.
If you’re someone who suffers from jet lag, it may be worth giving this new process a go.
Dave Asprey, the founder of the Bulletproof Diet, which claims to be able to help people improve their biochemistry, body and mind, says the trick to overcoming jetlag is reconnecting with the earth.
According to The Sun Asprey wrote in his book Head Strong that flying can disrupt the electrical charge in our body’s water cells, resulting in a tired feeling.
“When you go up in an aeroplane, you build up a static charge in your body that slows the mitochondrial function,” he said.
“In other words, the battery in your body doesn’t hold a charge as well because you were disconnected from the earth.”
To overcome it, he recommends ‘grounding’ where you walk barefoot on the earth after arriving in your holiday destination or when you return home. Apparently grass, dirt and sand work just fine.
While there may be no miracle cure to jet lag, it certainly helps to get a good sleep before you leave as this will make the effects a little less than if you got a bag night’s sleep.
On the plane, remember to drink plenty of water, wear comfortable clothing, nap, eat small meals and limit alcohol and caffeine as much as possible.
