It’s the holiday season now, with many families travelling abroad. One of the most common questions asked is about jet lag, especially how to prevent it.
What is Jet Lag?
Jet lag is a problem of the modern world — we travel faster than our body clocks can adjust. Since every cell in the body has a daily rhythm, jet lag affects everyone, child and adult regardless. It is not just about being tired, but a combination of being too awake or too tired, often with a general feeling of being unwell.
Jet lag is a common issue when travelling out of Singapore, and is typically much worse when you are heading east than west.
How Do We Recover From Jet Lag?
Usually, recovery from jet lag takes one day for every hour of change in the time zone, therefore, travel to Europe or the USA can potentially disrupt sleep for more than a week until our bodies adjust.
However, children may often take much less time to adjust, especially children less than 3 months old (as most of them wake every few hours to feed) and children below the age of 2 years (as many of them are poor sleepers and wake often at that phase).
How to Beat Jet Lag?
There is some good science in helping our bodies adjust more quickly to or avoid jet lag entirely.
a) Sunlight appears to be the best way to adjust our body clock.
Light acts to delay your body’s release of melatonin,which helps to promote sleep. So afternoon sun helps more when you fly west. When coming home from the east, morning sun may help.
b) Timing your flight
Timing your flight can help you to arrive in the late afternoon or evening. This is particularly helpful if you have a child who just won’t sleep on flights.
Some people recommend overnight/red-eye flights so that the travel itself may be easier with a child sleeping through the flight. But if you have a poor sleeper, many times the noise and dry air of a plane only makes it harder for your child to sleep, giving you a grumpy and overtired child.
c) Adjust your sleeping hours
Try to wake up in the morning and stay up until evening, but for children, keep nap times as close to what they were in your home country (e.g. an 11AM nap in Singapore should still try to be as close to 11AM local time of your destination country).
While there is also the advice to adjust bedtime and waking times by 30 minutes a night prior to travel until you match your destination country, it is not really practical for time zones 8-12 hours apart from Singapore.
