Short answer

Set the seat and lumbar support before you leave, sit back fully rather than perching, and move every hour — ankle circles, calf raises, standing where possible. Most journey discomfort comes from a poor initial position held for hours, not from the duration itself.

A long journey is several hours in a fixed position, so a small setup error becomes a real ache. Nearly all of it is decided in the first minute and then endured.

Safety

Long periods of immobility raise the risk of blood clots in the legs, particularly on flights over about four hours and for anyone with a history of clots, recent surgery, pregnancy or certain conditions — ask a GP about precautions before travelling if any apply. Swelling, pain or warmth in one calf after a long journey needs urgent medical attention. Never adjust a car seat while driving.

Step by step

Set the seat up before setting off.Adjusting at 70mph or once wedged in an aircraft seat is difficult and usually not done. Two minutes at the start is worth more than anything else here.
Sit right back into the seat.Hips as far back as they go, so the backrest supports you. Perching forward means your own muscles hold you up for hours, which is the main cause of back ache on a journey.
Set the lumbar support to fill the gap.It should meet the inward curve of your lower back without pushing you forward. If the seat has none, a small rolled towel or a cushion in the same place works well.
Get the seat height and angle right in a car.High enough to see clearly, with thighs supported along most of their length and a slight downward slope. A seat base tilted back compresses the lower back.
Set the backrest to about 100 to 110 degrees.Slightly reclined rather than upright. Bolt upright loads the lower back; too reclined means craning forward to see.
Position the headrest correctly.The middle of it level with the top of your ears and close to your head. It is a safety device rather than a comfort one and most are set far too low.
Keep the steering wheel close enough.Elbows slightly bent with hands on the wheel. Reaching for it pulls the shoulders forward and off the seat back, which causes neck and shoulder ache.
Support your feet if they do not reach the floor.A bag under them on a train or plane. Dangling feet put the whole leg's weight on the underside of the thighs, which restricts circulation.
Move every hour, on a schedule.Ankle circles, heel and toe raises, tensing and releasing calves, shoulder rolls, gentle trunk turns. Set a reminder rather than relying on noticing.
Stop and walk every two hours when driving.Standard advice for a reason — it addresses circulation, stiffness and concentration together. Ten minutes and a short walk.
Take the wallet out of your back pocket.Sitting on it tilts the pelvis and is a genuine and easily fixed cause of one-sided ache on a long drive.
Consider a neck pillow if you may sleep.A proper one stops the head dropping sideways, which is what causes the neck pain people arrive with. A rolled scarf works.
Drink enough despite the inconvenience.Deliberate dehydration to avoid stops causes headaches and tiredness, and it does not help circulation. Plan the stops instead.
Dress for it.Nothing tight at the waist or knees, and layers for changing temperature. Restrictive clothing over hours is a common and unnoticed cause of discomfort.
Take clot risk seriously on long flights.Move regularly, keep hydrated, and ask a GP about compression stockings or other precautions if you have any of the risk factors.

Tips

Two minutes setting the seat up before you leave is worth more than anything you can do during the journey.
Set an hourly reminder to move. Relying on noticing means it happens once, three hours in.
Wallet out of the back pocket. It is the single most overlooked cause of one-sided ache on a long drive.

Common mistakes

Perching forward off the seat back — Your own muscles then hold you upright for hours, which is the main cause of back ache on a journey. Sit hips fully back into the seat.
Drinking less to avoid stopping — It causes headaches and tiredness and does nothing for circulation, which is a real consideration on long journeys. Plan the stops instead.

If it doesn't work

Lower back ache after an hour

Cause: Sitting forward, or no lumbar support — Fix: Sit fully back and add a rolled towel at the inward curve of the lower back.

Neck and shoulder ache while driving

Cause: Reaching for the wheel, or a low headrest — Fix: Move the seat closer so elbows are slightly bent, and raise the headrest to ear level.

Legs numb or tingling

Cause: Pressure on the underside of the thighs, or restrictive clothing — Fix: Support the feet, adjust the seat height, and avoid anything tight at the waist or knees.

Ankles swollen on arrival

Cause: Immobility and fluid pooling — Fix: Ankle circles and calf raises hourly, and walk whenever possible. Persistent one-sided swelling with pain needs urgent medical attention.

One-sided hip or back ache

Cause: Often a wallet or phone in a back pocket — Fix: Empty the back pockets before setting off.

Questions people ask

How do I stop my back hurting on a long drive?

Set the seat up before setting off, sit with your hips fully back so the seat supports you, add lumbar support at the inward curve, and stop to walk every two hours.

How often should I move on a long flight?

Every hour at least — ankle circles, calf raises and walking the aisle where possible. Keep hydrated, and ask a GP about precautions if you have any clot risk factors.
