How To Get Over Jet Lag

Whether you’re traveling for business, vacation, or an athletic competition, a big trip is usually cause for excitement. Unfortunately, problems can arise from the process of traveling. When long airplane flights are involved, jet lag is frequently encountered.

Jet lag is commonly associated with international plane travel, but it can arise on any flight that goes east or west across three or more time zones. Jet lag frequently causes sleep disruptions, which can throw your body’s internal clock out of sync with the day-night cycle at your destination.

Knowing how to prevent and recover from jet lag can help you maintain your sleep schedule and overall wellness during your travels, so you can make the most of your trip.

What Is Jet Lag?

Jet lag is a disruption of the body’s circadian rhythm that occurs with plane travel across three or more time zones Trusted Source Centers for Disease Control and Prevention (CDC) As the nation’s health protection agency, CDC saves lives and protects people from health threats.

Not everyone is affected by jet lag. Trip itinerary and individual factors can affect the severity and duration of jet lag.

What’s the Best Way To Reduce or Resolve Jet Lag?

The key to getting over jet lag is to get your body’s circadian rhythm aligned with the sunrise and sunset schedule at your destination. Many steps can also be taken to minimize symptoms caused by jet lag.

Realigning Your Circadian Rhythm

Overcoming jet lag depends on getting your body’s 24-hour internal clock synchronized with the 24-hour day at your destination. However, the best way the achieve this varies, depending on factors specific to your trip:

• Whether you’re traveling east or west. (Eastward travel is associated with an increased likelihood of jetlag.
• The number of time zones crossed. (Crossing more than three time zones increases the likelihood of jetlag).
• Total travel time, including stop-overs
• Flight arrival time
• Length of your trip (including subsequent flights)
• Your normal sleep schedule
• Plans during your trip, including any scheduled obligations

Because of these variables, there’s no single remedy for jet lag. Instead, quickly overcoming jet lag typically requires a plan that involves light exposure and melatonin. Both are power influencers of the circadian rhythm and can help retrain your internal clock Trusted Source National Library of Medicine, Biotech Information The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.

Proper timing Trusted Source National Library of Medicine, Biotech Information The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.

In fact, light exposure and melatonin intake at the wrong time of the day can further desynchronize your circadian rhythm and exacerbate jet lag.

Even with a well-developed plan, you may still experience symptoms of jet lag. Every individual adjusts differently to a rapid time zone change, but working to reorient your circadian rhythm can reduce the chances that jet lag will negatively impact your trip.

Light Exposure

Light, especially natural light, has the biggest influence on circadian rhythm. Light from the sun, even on a cloudy day, is a critical signal interpreted by the brain to regulate our internal clock.

Exposure to natural light at your destination speeds up the process of acclimating to the new time zone; however, you may not want to immediately rush outside. Depending on how far you’ve traveled and the time you land, it may be better to avoid light when you first arrive and then have extended light exposure earlier the next day.

Artificial light, including electronic devices, also affects circadian rhythm. For this reason, try to avoid artificial light during planned periods of darkness and sleep.

When natural light exposure isn’t an option, a high-powered lamp used for light therapy, also called a lightbox, can provide higher illuminance with a greater circadian effect.

Melatonin

The hormone melatonin is naturally made by the body. Melatonin production usually starts at night in the hours before your normal bedtime. Two key functions of melatonin are helping sleep initiation and regulating your circadian rhythm.

When your circadian rhythm is disrupted by jet lag, the timing of melatonin production can be thrown off. A number of studies have found that taking melatonin supplements Trusted Source National Library of Medicine, Biotech Information The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.

Melatonin is sold as an over-the-counter dietary supplement available without a prescription. Some prescription drugs also boost melatonin levels.

Most people can take melatonin without significant side effects, but in some people, it can cause grogginess or stomach problems and may have interactions with other medications. As with any drug or supplement, it’s best to consult with your doctor before taking melatonin.

Pre-Trip Adjustments to Your Sleep Schedule

For many travelers, the best way to get over jet lag is to take steps to prevent it.

You may achieve this by gradually shifting your circadian rhythm in the days leading up to the flight. Then, you’ll be more adjusted to the time zone at your destination when you arrive.

A revamped sleep schedule along with strategically timed light exposure and melatonin supplements can help adjust your circadian rhythm. These changes require careful coordination and may pose logistical challenges for many travelers. However, for people who prioritize optimal physical and mental performance after travel, such as athletes and business executives, the effort may be worth it.

Tools to Plan a Trip and Avoid Jet Lag

With so many factors to account for, planning to avoid jet lag can feel overwhelming. Several online resources and apps are can help you generate a tailored strategy to reduce jet lag based on the details of your trip.

You can also consult with your doctor, a sleep specialist, or a travel clinic for specific advice about overcoming jet lag given your travel plans and personal health history.

• Get solid sleep before your trip: Try to start off by getting plenty of uninterrupted sleep in the nights leading up to your flight.
• Bring helpful accessories: A sleep mask, earplugs, and comfortable clothes for sleep are examples of items that can decrease disruptions when sleeping in a new place.
• Avoid unnecessary stress: Being anxious can impede quality sleep and exacerbate symptoms of jet lag.
• Don’t over-schedule your first days: Anticipate some degree of jetlag symptoms and don’t overbook your first days at your destination. Budget enough time for sleep and keep buffers in your schedule in case you aren’t feeling well.
• Limit alcohol: Alcohol reduces the overall quality of your sleep. Therefore it’s best to cut out or limit alcohol both in-flight and after arriving.
• Don’t overdo caffeine: Caffeine can give boost alertness in the short-term, but use it in moderation. Too much caffeine can leave you jittery and may linger in your system, making it difficult to fall asleep.
• Stay hydrated: Airplane cabins can induce dehydration Trusted Source National Library of Medicine, Biotech Information The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.

• Stretch on the plane: It’s important to stand up and move a few times to prevent muscle stiffness and reduce the risk of blood clots.
• Exercise: Exercise has beneficial effects on the mind and body, so make time to be physically active at your destination. While research is inconclusive, properly timed exercise may also help align your circadian rhythm.

Can Naps Help With Jet Lag?

A quick nap may help you overcome excess daytime sleepiness related to jet lag, but it’s important to be careful with naps. If you nap for too long or too late in the day, it may throw off your sleep schedule even more. Try to keep naps less than 30 minutes and nap at least eight or more hours before your planned bedtime.

Can Sleep Aids Help With Jet Lag?

Sleep aids other than melatonin, including both prescription sleeping pills and over-the-counter drugs, do not cure jet lag because they don’t realign your circadian rhythm. That said, if jet lag is causing sleep deprivation, a sleep aid may help address that symptom.

Most sleeping pills have a powerful effect that can make you feel out-of-sorts and groggy for longer than expected, including after you wake up. The risk of falls or accidents is often higher after taking sleep medications. Frequent use of sleep aids may also make it harder to recognize an ongoing case of jet lag.

Before taking any sleep aid, it’s best to consult your doctor. They can review the potential benefits and side effects and offer advice on how to safely take them, based on your specific travel plans.
