Tech Tools Helping Travellers Beat 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’s like your body saying, “Wait, why am I awake when I should be sleeping?” This can cause tiredness, difficulty sleeping, and even stomach problems. It can take a few days for your body to catch up, leaving you feeling jet-lagged.

The science behind jet lag lies in the body’s production of the hormone melatonin, which helps regulate sleep-wake cycles. Exposure to light suppresses melatonin production, signalling to our bodies that it’s time to be awake. However, crossing time zones can confuse this process, disrupting our sleep patterns.

Luckily, there are steps and tools available to help avoid the onset of jet lag. By using these resources effectively, travellers can minimise the impact of jet lag on their well-being and enjoy a smoother transition when crossing time zones.


Tips To Dodge Jet Lag


There are precautionary measures available to mitigate the effects of jet lag or prevent it entirely. These measures can significantly alleviate the discomfort associated with traveling across time zones. By implementing these precautions, individuals can better adapt to new time zones and maintain their well-being during travel.


Adjust your sleep schedule: Start adjusting your sleep routine a few days before your trip by going to bed and waking up closer to the local time of your destination.

Stay hydrated: Drink plenty of water before, during, and after your flight to prevent dehydration, which can worsen jet lag symptoms.

Get sunlight exposure: Spend time outdoors in natural sunlight upon arrival to help reset your body’s internal clock.

Avoid caffeine and alcohol: Limit your intake of caffeine and alcohol, as they can disrupt your sleep patterns and exacerbate jet lag.

Take short naps strategically: If you need to nap upon arrival, keep it short (20-30 minutes) to avoid interfering with your nighttime sleep schedule.

Stay active: Engage in light exercise or take walks to stay awake and alert during the day, but avoid vigorous exercise close to bedtime.

Consider melatonin: Consult with a healthcare professional about using melatonin supplements to help regulate your sleep-wake cycle if needed.
