lets cure jet lag!

Jet Lag Meaning

Jet lag is a common issue when you travel across different time zones. It’s not just one time; it’s your body’s internal clock trying to catch up with the new time. This can make you feel tired and a bit off, like your body and the clock, aren’t in sync.

But don’t worry, there are ways to deal with it and enjoy your trip!

Jet lag happens when your body’s internal clock is out of sync with the time zone you’re in. This can make you feel tired and unwell.


If you live in New York (Eastern Time) and fly to India (Indian Standard Time), the time difference can be 9.5 hours. Your body is used to one time, but now it’s a whole lot different.

Best Way to Cure Jet Lag

  • Gradually Adjust Your Schedule – Before your trip, try to sleep and eat at the times of your destination.
    • Example – If you’re going to Mumbai from New York, start shifting your bedtime and mealtime closer to Mumbai’s hours.
  • Stay Hydrated – Drink lots of water to prevent dehydration during the flight.
  • Use Light Right – Get sunlight during the day at your destination to help your body adjust.
    • Example – If you arrive in Delhi early in the morning, spend time outdoors to signal to your body that it’s daytime.
  • Avoid Alcohol and Caffeine – These can mess up your sleep and make jet lag worse.
  • Example – Instead of having a lot of coffee on a flight, opt for water.
  • Short Naps – If you’re really tired after landing, a short nap can help. But don’t sleep too long or too late.
    • Example – A 20-minute nap is better than a 2-hour one.
  • Use Apps – Apps like Timeshifter can create personalized plans based on your travel details to reduce jet lag.
    • Example – Input your flight times, and the app will tell you when to seek light or sleep to beat jet lag.
  • Remember, it can take a day or two for your body to fully adjust.

Be patient, and soon you’ll be enjoying your trip without the lag!

Important FAQs about Jet Lag

What is Jet lag?

Jet lag is a condition that happens when your body’s internal clock is out of sync with the time zone you’re in. It can make you feel tired, and disoriented, and affect your sleep, digestion, and overall well-being after long flights.

What causes jet lag?

Jet lag occurs because your body’s internal clock, which regulates your sleep-wake cycle and other bodily functions, needs time to adjust to a new time zone. Traveling quickly across multiple time zones disrupts this clock, causing the symptoms of jet lag.

What are the common symptoms of jet lag?

Jet lag can cause various symptoms, including fatigue, insomnia, difficulty concentrating, irritability, digestive issues, and general discomfort. The severity of symptoms can vary depending on the number of time zones crossed and individual differences. Refer here.

How long does jet lag typically last?

The duration of jet lag varies from person to person and depends on factors like the number of time zones crossed and individual adaptability. Typically, it takes about a day for your body to adjust to each time zone crossed. So, for a three-hour time difference, it may take around three days to fully recover.

Can jet lag be prevented or minimized?

While you can’t completely prevent jet lag, you can take steps to minimize its impact. Strategies include gradually adjusting your sleep schedule before your trip, staying hydrated, avoiding alcohol and caffeine, and seeking exposure to natural light at the destination.
