We have all experienced it. That general feeling of being out of sorts when traveling to a new time zone. We are ready to experience our adventure and yet physical we may not be at our best. Our bodies are the last to know that there is a change in time and location and sometimes is slow to adjust. Our body’s internal clock is designed to follow a roughly 24-hour cycle, which helps regulate various physiological functions such as sleep, hunger, and alertness. Our bodies need time to adjust to the change.
What is jet lag? Jet lag is a temporary sleep disorder that occurs when your body’s internal clock (circadian rhythm) is disrupted after traveling across multiple time zones. It commonly affects people who travel by air, as they quickly move from one time zone to another. The symptoms of jet lag can include fatigue, sleep disturbances, difficulty concentrating, irritability, and digestive issues. It usually takes a few days for your body to adjust to the new time zone and for your internal clock to realign with the local time. There are various strategies to help manage jet lag, such as adjusting your sleep schedule before travel, staying hydrated, exposing yourself to natural sunlight, and gradually adjusting to the new time zone.
When we rapidly travel across different time zones, our body clock gets disrupted because it doesn’t immediately synchronize with the new local time. This leads to a mismatch between our internal clock and the external environment, resulting in symptoms like fatigue, sleep disturbances, difficulty concentrating, gastrointestinal issues, and mood changes.
Exposure to daylight plays a significant role in regulating our internal clock. The hormone melatonin also influences our sleep-wake cycle, and disruptions in its production during travel can contribute to jet lag. Additionally, other factors like dehydration, cabin pressure changes, and limited physical activity during flights can further aggravate the symptoms.
To minimize the effects of jet lag, it can be helpful to gradually adjust your sleep schedule a few days before travel, stay well-hydrated during the flight, expose yourself to natural light upon arrival, and consider taking short naps strategically to ease the transition.
-
Adjust your sleep schedule: Before your trip, slowly adjust your sleep schedule to align with the time zone of your destination. Gradually shift your sleeping and waking times by an hour each day leading up to your departure.
-
Stay hydrated: It’s important to stay well-hydrated before, during, and after your flight. Drink plenty of water and avoid alcohol and caffeine, as they can dehydrate you and disrupt your sleep patterns further.
-
Get sunlight: Exposure to natural light can help reset your body’s internal clock. Spend time outdoors during daylight hours upon arrival at your destination. If it’s not possible, open the curtains in your room and let natural light in.
-
Nap strategically: Short power naps can provide a quick energy boost, but be cautious not to nap for too long or too late in the day. Keep your naps brief (around 20-30 minutes) and try to avoid napping closer to bedtime.
-
Stay active: Engage in light exercise or take a walk upon arrival to help combat fatigue and increase alertness. Regular physical activity can also aid in adjusting your body clock faster.
-
Avoid heavy meals: Stick to light, healthy meals during your flight and upon arrival. Heavy meals can make you feel lethargic and disrupt your digestion, complicating your adjustment to the new time zone.
-
Consider melatonin: Melatonin is a hormone that helps regulate sleep. Taking it in supplement form, following the recommended dosage and consulting your healthcare provider first, may help reduce jet lag symptoms for some individuals.
Remember, these tips can help manage jet lag, but everyone responds differently. It might take a few days for your body to fully adjust, so be patient with yourself.█
