Why Long Journeys Leave Travellers More Tired Than Expected
Long trips can make people tired even when they do not exercise much.
In an aeroplane, the air pressure is lower than at ground level, so the body may work slightly harder to get oxygen.
The air is also very dry, which can make the body lose water.
Dehydration may cause headaches and tiredness.
Vehicles vibrate and move, so muscles make many tiny adjustments to keep the body steady.
Noise and bright lights can also tire the senses.
Sitting for a long time can slow blood circulation in the legs.
Taking short walks or moving the ankles can help blood flow.
Drinking water and avoiding alcohol and caffeine may help travellers feel better.
Long journeys can cause fatigue even when travellers remain seated and appear to be resting.
Aircraft cabins are pressurised to the equivalent of 6,000–8,000 feet, reducing available oxygen and mildly increasing the body’s workload.
Very dry cabin and air-conditioned transport environments can contribute to dehydration, headaches, and lethargy.
Vehicle vibrations, noise, motion, and bright terminal lights create sensory and postural fatigue.
Prolonged sitting can reduce blood circulation, while walking and seated ankle rotations may help reduce sluggishness and stiffness.
- Who
- Travellers taking journeys by car, train, or aeroplane.
- What
- Long journeys can produce unexpected fatigue through dehydration, reduced circulation, mild oxygen reduction, sensory strain, and continuous muscle adjustments.
- Where
- In cars, trains, and especially commercial aeroplane cabins and terminals.
- When
- During journeys lasting several hours and after reaching the destination.
- Why
- Extended travel exposes the body to low cabin pressure, dry air, motion, noise, bright lights, prolonged sitting, and reduced movement.
Key facts
- Aircraft cabin pressure
- Commercial aeroplanes are pressurised to an altitude equivalent of 6,000–8,000 feet, or up to 2,400 metres.
- Cabin humidity
- Aeroplane cabin humidity frequently falls below 20 per cent.
- Oxygen effect
- Lower air pressure can reduce the amount of oxygen the blood absorbs, creating mild hypoxia.
- Dehydration effects
- Fluid loss during travel can contribute to headaches, dry skin, and lethargy.
- Muscle strain
- Core muscles make subconscious micro-adjustments to counter vehicle movement.
- Circulation advice
- Short walks and seated ankle rotations may help maintain blood flow and reduce stiffness.
