Altitude, long rides and tired legs: small habits for the trip home from the mountains

Each summer, when the climbing season opens on Mount Fuji, the same advice goes out to the crowds heading up: start slowly, rest at the fifth station before climbing higher, drink water, and turn back if your head starts to pound. Every season, some climbers turn back because of altitude sickness.

The same thin air greets visitors to Colorado's mountain towns, and the trip home asks something of the body too. If you are planning the return from a ski week, pages describing an Aspen to Denver shuttle are one place to look at handing the mountain driving to someone else. This piece explains what altitude and a long ride do to the body, and the simple checks that make the last days of a trip and the drive down easier.

How altitude works on the body

Higher up, the air is thinner, so each breath brings in less oxygen than it would at sea level. The body adjusts over a few days by breathing faster, raising the heart rate and making other slower changes. Until it catches up, many visitors feel the effects in mild ways: a headache, poor sleep, a loss of appetite, nausea, tiredness, or feeling breathless on stairs that would be nothing at home.

This mild form, often called acute mountain sickness, is common in mountain resort towns and usually settles as the body adjusts. A few things tend to make it worse: going up quickly, heavy exercise in the first day or two, alcohol, and not drinking enough water in the dry mountain air. Most health bodies agree on one point above all others. The most reliable relief for altitude symptoms is going lower, which is why many people feel noticeably better somewhere on the road down.

Denver itself sits well above sea level, which is why it is called the Mile High City, so the drop from the mountains does not bring you all the way down. For most healthy visitors, though, the difference between a ski town and the city is enough for symptoms to ease, and the tired legs of the last ski day are a bigger concern than the altitude by the time you reach the plains.

Sleep deserves a word of its own. Many people sleep lightly at altitude, waking often or having vivid dreams, and some notice their breathing becomes uneven at night. This is common in the first nights and usually improves, but it means many travelers start the trip home already short of rest.

Rarely, altitude illness becomes serious, affecting the lungs or the brain. Those warning signs are covered in the last section and should never be waited out.

The last days of the trip

The final days of a ski week are often the hardest on the body. Legs are tired, sleep at altitude may have been patchy, and there is usually a farewell dinner. A short list of checks helps:

1. Drink water steadily through the day. Mountain air is dry, and you lose more water than you notice through breathing and exercise.
2. Go easy on alcohol, especially on the last night, when you will want a clear head for packing and travel.
3. Protect your skin and eyes. Sunlight is stronger at altitude, and snow reflects it, so sunscreen, sunglasses and lip balm matter even on cloudy days.
4. Eat proper meals, even if your appetite is low. Small, regular meals are easier than one large one.
5. Take the last morning gently rather than squeezing in a final hard run.
6. Pay attention to symptoms that are getting worse instead of better. That is a different situation from a mild headache that comes and goes.

Children and older relatives may not say how they feel, so it helps to ask. A child who is unusually cranky, off their food or not sleeping, or an older parent who seems more breathless or muddled than usual, deserves the same attention you would give your own symptoms.

Sitting still on a long ride

The road from the high country back to Denver takes several hours, and much of it is spent sitting in one position after days of hard exercise. Stiff backs, tight hips and swollen ankles are common results. In Japan, the term "economy class syndrome" is widely known for a related reason: after large earthquakes, health authorities have repeatedly warned people sheltering in cars that sitting cramped for long periods raises the risk of blood clots in the legs. The risk applies to long journeys of any kind.

Simple habits help:

• Get up and walk around at every stop, even for a minute or two.
• While seated, flex your ankles, circle your feet and shift position regularly.
• Wear loose, comfortable clothes and avoid sitting with your legs crossed for long periods.
• Keep drinking water during the trip.
• If you have had a blood clot before, have recently had surgery, are pregnant or have another condition that raises the risk, ask your doctor before a long journey.

Mountain roads also bring motion sickness. Sitting near the front, looking out at the horizon rather than at a phone or book, keeping some fresh air moving and eating a light meal beforehand all help many people. If you know you get travel sick, ask a pharmacist before the trip about options that suit you, rather than guessing at medicines.

Handing over the driving

In Japan, group travel by chartered bus is an old habit: company outings, school trips and neighborhood excursions often go this way, partly so that nobody has to drive and everyone can rest. There is a sensible health point inside that custom.

After several days of skiing, many drivers are more tired than they realize. Winter mountain roads can mean snow, ice and low light in the late afternoon, which ask for full attention. Drowsy driving is a recognized hazard, and tiredness creeps up on a long, quiet stretch of road. When someone else drives, everyone in the group can sleep, stretch at stops, drink water and simply watch the mountains slip past.

Luggage is the other strain people forget. Ski bags, boots and suitcases get lifted in and out of lodgings and vehicles several times on a travel day, often by tired people in a hurry. Bend at the knees, keep the load close to your body, avoid twisting while you lift, and share heavy bags between two people. A sore back from lifting a ski bag is one of the more avoidable souvenirs of a mountain trip.

Whatever transport you choose, it helps to plan the trip home around the body's needs rather than the schedule alone. Leaving after a proper breakfast, not after a late night, makes a real difference. So does allowing time for stops rather than pushing straight through.

When to see a doctor

Mild altitude symptoms usually ease with rest, water and going lower. Get medical help promptly, and arrange to go down if you are still at altitude, if anyone has breathlessness while resting, a cough that brings up frothy or pinkish fluid, confusion, unusual drowsiness, clumsiness or trouble walking in a straight line, or a severe headache that does not ease. These can be signs of serious altitude illness and need urgent care.

After the journey, pain, swelling, warmth or redness in one calf can be a sign of a blood clot and should be checked quickly. Sudden breathlessness, chest pain or coughing up blood is an emergency. Anyone with a heart or lung condition should talk to their doctor before traveling to high altitude at all, and ask what to watch for.

Yojo habit: On every long ride, stand up and walk for a minute at each stop, and drink a cup of water before you get back on board.

The one thing to remember

Altitude and long hours of sitting both ask the body to adjust, and both reward the same simple care: water, steady movement and rest. Plan the trip home so the people in it can actually rest, and pay attention to any symptom that gets worse instead of better.
