Quick Answer: Managing Jet Lag
Jet lag occurs when your internal clock is misaligned with the local time zone. Eastward travel is harder than westward. Recovery takes roughly 1 day per time zone crossed. The most effective strategies: timed light exposure (bright light in the morning at your destination), low-dose melatonin (0.5-3 mg at destination bedtime), pre-trip schedule shifting, and staying hydrated. Avoid relying on sleeping pills or alcohol to sleep on planes.

Why Jet Lag Happens
Your circadian rhythm is controlled by a master clock in the brain (suprachiasmatic nucleus) that runs on roughly a 24-hour cycle, synchronized by light exposure. When you cross time zones rapidly, your internal clock remains set to your departure time zone. Your body thinks it is midnight when the local clock says 8 AM, or vice versa.
It takes your body about one day per time zone to fully adjust. Crossing 6 time zones (Toronto to London) means roughly 6 days for complete adaptation. During this adjustment, you experience fatigue, insomnia, digestive issues, difficulty concentrating, and general malaise.
Eastward Is Harder Than Westward
The human circadian clock naturally runs slightly longer than 24 hours (about 24.2 hours). This means your body finds it easier to delay sleep (stay up later) than to advance it (go to bed earlier). Westward travel requires delaying, which is more natural. Eastward travel requires advancing, which fights your biology. This is why flying from Canada to Europe typically causes worse jet lag than the return trip.
Common Canadian Travel Routes
Toronto to London (5 hours ahead): Moderate jet lag. Arrive in the morning feeling exhausted. Stay awake until evening using bright light exposure.
Toronto to Tokyo (14 hours ahead): Severe jet lag. Consider intermediate adjustment. Pre-shift your schedule 2-3 hours before departure.
Toronto to Vancouver (3 hours behind):
Mild jet lag. Most people adjust within 1-2 days. Westward shift is easier.
Toronto to Honolulu (5 hours behind): Moderate. You will want to sleep early and wake early at first. Seek evening light to push your clock later.
Science-Backed Strategies
Jet Lag Action Plan
Before your trip: Shift your sleep schedule 30-60 minutes per day toward your destination time, starting 3-4 days before departure.
On the plane: Set your watch to destination time immediately. Sleep if it is nighttime at your destination. Stay awake if it is daytime. Avoid alcohol (dehydrating and sleep-fragmenting). Stay hydrated.
At your destination: Get bright light exposure at the right time. For eastward travel: morning light, avoid evening light. For westward travel: evening light, avoid morning light. Take 0.5-3 mg melatonin at the destination bedtime. Avoid napping longer than 20 minutes. Exercise moderately during daytime hours.
Come Home to a Great Sleep
One thing seasoned Canadian travellers know: coming home to a comfortable bed makes jet lag recovery much faster. If your mattress is uncomfortable on a normal night, recovering from jet lag on it is miserable. At Mattress Miracle, we want your first night back in Brantford to feel like the best part of coming home. A quality mattress is your recovery room after every trip.

Does melatonin help with jet lag?
Yes. Melatonin is most evidence-supported for jet lag. Take 0.5-3 mg at bedtime in your destination time zone. Start the first night of arrival. Use for 3-5 days. It helps reset your circadian clock faster.
Should I take sleeping pills on the plane?
Sleep medications on planes carry risks: reduced mobility (DVT risk), disorientation, and poor sleep quality despite appearing asleep. Short flights rarely benefit. For long-haul flights, discuss with your doctor. A neck pillow, eye mask, and earplugs are safer.
How long does jet lag last?
Roughly one day per time zone crossed for full adjustment. Eastward travel takes slightly longer than westward. Most symptoms (fatigue, sleep disruption) improve within 3-5 days even for long-distance travel.
Does coffee help with jet lag?
Coffee can help with daytime alertness at your destination but avoid it within 6-8 hours of your target bedtime. Strategic caffeine use (morning only at destination) supports adaptation. Unlimited coffee backfires by preventing nighttime sleep.
Do frequent flyers adapt to jet lag?
Somewhat. Frequent travellers develop better coping strategies and recognize their patterns. But the circadian clock does not "get used to" jet lag. Pilots, flight attendants, and business travellers still experience physiological disruption with each time zone change.
