How I defeated jet lag in 24 hours

I just got back from Southeast Asia (Thailand, Hong Kong) and landed in Canada (Vancouver) last Thursday. Typically when making this east-west trip, I suffer from at least 4-6 days of jet lag, but this time, I basically got over it in 24 hours.

It was thanks to the advice given to me by researcher Ian Dunican ( @sleep4perform on Twitter) who was kind enough to give me a free analysis and sleep prescription.

My flight was less than ideal. I woke up at 7am Hong Kong time for a 10am departure in Hong Kong. I flew for the first part of my connection from Hong Kong to Tokyo, where I had a 3-hour layover. The Tokyo flight departed at 6:43pm and would eventually arrive in Vancouver at 10:30am local. That's 2:30am at my point of origin, so that's a rough one - I'd be arriving in the morning, at what would be a couple hours past my bedtime in Hong Kong.

On the flights I consumed no caffeine and very little food. I slept at much as possible on the plane using eye shades and headphones and probably got about 4-5 hours of total sleep between the two flights.

Upon arrival in Vancouver I had some coffee and walked around. We opened all the windows in the apartment to let in as much sunlight as possible. At around 4pm I succumbed to a 30-minute nap, but forced myself to wake up after it. I struggled until about 7pm when I went down to the gym for an hour of cardio and 20 minutes of sauna.

After exercise, I took a 5-minute ice-cold Canadian shower (my own idea, not Ian's) and ate dinner. I tried to stay up until 10pm, but could only make it until 9pm.

I'd hoped to sleep in late, but my body woke me up at 5am, but not bad considering that's 9pm Hong Kong, right when my body would be starting to get tired.

On day 2, I went back off the caffeine. I did some light morning exercise (low-intensity kickboxing and BJJ session at the gym), came home, ate breakfast, and promptly passed out for two 90-minute naps. I was pretty worried that this would affect my sleep at night, but it didn't. At 7pm I did a moderate-intensity kickboxing class, came home, had dinner, and slept all the way to 9:30am, granted, with some wakeups in the middle of the night.

Mission accomplished! Thanks to Ian for the free analysis; I recommend you follow him on Twitter if you're at all interested in sleep and performance.
