Environment is everything

Cool, dark and quiet are the three keys to sleep. A supportive pillow will keep your neck aligned, and an eye mask and earplugs will block environmental disturbances.

Following your normal sleep habits like brushing your teeth, changing your clothes or performing a simplified version of your skincare routine can also get you in the mood for snoozing.

For Chan, setting the mood with calming music, nature sounds or aromatherapeutic essential oils can also help. For extra relaxation, he recommends deep breathing or meditation before takeoff to calm your mind and prepare your body for sleep.

Don’t lose sleep over it

Can’t fall asleep right away? Chan recommends reading a book or listening to calming music. "Sleep will find you one way or another,” he says.
