Exploring Jet Lag: What It Is and How to Avoid It

Introduction

Jet lag is an often unavoidable side-effect of air travel across several time zones. With the speed and convenience we have become accustomed to, jet lag is something most of us just accept as part of the deal. But with a better understanding of what jet lag is, how it works and how you can try to combat it, you could be well on the way to a more stress-free journey.

What Is Jet Lag?

Jet lag is a condition usually caused by travelling across several times zones. This disruption of your ‘circadian rhythm’ can lead to insomnia, headaches and general fatigue, with symptoms lasting anywhere between a few hours and a few days.

It is common when travelling through two or more time zone, but even just a one-hour time difference can have an effect. This is especially true if you have to change your working hours straight away on arrival at your destination, or if you’ve had to catch a 6am flight, for example.

How Does Jet Lag Work?

We all have an internal body clock known as the circadian rhythm that regulates when we feel we should be awake and when we should be asleep. It’s controlled by our hormones and is however, programmed to work on a 24-hour cycle.

When we travel hundreds or thousands of kilometres across time zones, our body clock is left in a state of confusion as it is no longer in alignment with the new daylight and dark cycle of the new environment. This causes the dreaded midnight insomnia, daytime fatigue and general sleepiness until our body clock can adjust to the new situation.

How To Fight Jet Lag

Whilst jet lag is an often unavoidable disruption to our circadian rhythm, there are a few things you can do to try and minimise its affects.

Hydrate: Staying hydrated is essential in counteracting jet lag as dehydration has been known to make jet lag symptoms worse. Ensure you drink plenty of water both pre and post-flight to minimise the risk of dehydration.

Adjust To The Time Zone Pre-Flight: Before you fly, adjust your sleep schedule to the local time of your destination, or at least the time zone you’ll be in during the middle of your journey. It may be worth having an extra rest during the day to compensate for the more restful night, so you’re not exhausted before you even step foot on the plane.

Light Exposure: A great (and enjoyable) way to help adjust your body clock is to expose yourself to natural light. When you’re tired, opt to spend a few minutes in the sunshine rather than resorting to caffeinated drinks or energy bars. This will help to reduce your cortisol levels, which will in turn help you to sleep better at night.

Summary

Whilst jet lag can be an unavoidable side-effect of air travel, there are ways you can try to counteract it. By following a few simple tips and paying attention to your circadian rhythm, you can minimise the effects of jet lag and make the journey just that bit more bearable.
