Staying Healthy During Your Ski Season

Ski resort environments are physically demanding — altitude, cold, daily exercise — and socially pressured in ways that reliably compromise your immune system and recovery. Late nights, drinking culture, dense communal living, and inconsistent food all stack on top of the physical load. Most seasonaires arrive expecting the physical side and underestimate the rest.

This is a practical guide to the specific health challenges of a ski season and what actually helps.

Why ski resort environments are hard on health

Altitude. Even at 1,000–2,000m, dry mountain air dehydrates faster than sea-level environments. At 2,000–3,000m — where many European and North American resorts sit — reduced oxygen partial pressure stresses the cardiovascular and immune systems noticeably in the first two to three weeks. You'll feel this as fatigue, broken sleep, and mild breathlessness before your body adapts. Treat the first two weeks as an acclimatisation period, not a period to push volume.

Dryness. Alpine winter air has very low humidity. Mucosal membranes in the nose, throat, and lungs — your first line of immune defence against airborne viruses — dry out faster in these conditions, reducing their effectiveness. This is a significant and underappreciated factor in why ski resort communities get ill.

Proximity. Resort communities are dense. Everyone uses the same chairlifts, bars, chalet bathrooms, and staff accommodation kitchens. Respiratory viruses move rapidly through resort populations. The first major snowfall of the season — which brings a surge of new arrivals — often coincides with the first wave of illness as the community's immunity establishes itself. Budget for getting ill in the first month. It's the norm, not the exception.

Social pressure. Late nights and drinking are embedded in resort culture. Both suppress immune function measurably: alcohol impairs T-cell response; sleep deprivation reduces cytokine production. A sustained pattern of 2am finishes and 8am starts across several weeks will result in illness. This isn't moralising — it's mechanics. Build rest into your calendar rather than reacting to it when you crash.

Practical immune support

Hydration. The single most consistently underestimated factor. Aim for 2.5–3.5 litres of water per day in dry alpine environments; ski days with high output need the upper end. Headaches, afternoon fatigue, and increased illness susceptibility are all consistent with chronic mild dehydration. A 1-litre water bottle on the mountain is not optional.

Vitamin D. Despite spending time outdoors, ski resort workers often develop significant Vitamin D deficiency across a season. High-SPF sunscreen — necessary on the mountain — limits synthesis. Short daylight hours in December and January, plus fully covered skin in cold weather, compound this. A daily supplement of 1,000–2,000 IU is cheap, safe, and well-evidenced. Take it from the start of the season.

Sleep. Seven to eight hours is the evidence-based target for immune function and recovery. Budget this into your après calendar actively — three consecutive late nights will make the fourth a forced rest day whether you planned it or not. Prioritising sleep is not a sign of failing to embrace resort life; it's why some people finish the season healthily and others don't.

Food. Chalet staff often eat well — the food they cook for guests. Hotel and restaurant staff eat staff meals that vary significantly by employer. If your staff meals are heavy on carbohydrate and light on vegetables, supplement them actively. A weekly supermarket shop for fruit (kiwi and citrus are practical for mountain environments), vegetables, and protein goes a long way. This sounds obvious and is consistently neglected.

Managing illness when it arrives

Assume you'll get ill at least once during a season — one respiratory illness is a realistic baseline given the environment. When it happens:

Take the sick day early. Working ill in a customer-facing role passes illness to guests and colleagues. More practically, a one-day rest taken when symptoms first appear typically results in faster recovery than pushing through for three days and then being forced off for five. This is not a hard rule — judge by severity — but the instinct to "push through" in resort culture often makes illness worse and longer.

Know your sick leave policy before you're ill. French employers require a médecin's arrêt de travail (sick note) for sick leave to be paid — this requires a GP visit, which in ski resorts means the local cabinet médical. The cabinet is often a short bus ride from the resort, not on-mountain. Know where it is before you need it. Some employers will require this note for absences of even one day; others apply it from day two or three. Find out in advance.

Rest and hydration outperform most OTC treatments. For typical respiratory illness — the majority of what circulates in resort communities — paracetamol for fever and aches, hydration, and sleep are more effective than most combination cold products. Decongestants can be useful for symptom management; antihistamines cause drowsiness that may help sleep but is not a treatment. If symptoms worsen after day five, or include fever over 39°C, shortness of breath, or chest pain, see a doctor.

The physio reality

Skiing five to six hours per day, five to six days per week, is physically demanding in ways that compound over a season. Most injuries happen in two windows: weeks one and two (unfamiliar terrain, overconfidence, poor conditioning arriving into the season) and weeks eight to ten (fatigue, complacency, reduced reaction time).

Reduce risk in both windows with the same approach:

• Warm up before skiing. Ten minutes of dynamic movement — leg swings, hip circles, squat to stand — before your first run. It takes ten minutes and is almost universally skipped by people who haven't had a knee injury.
• Cool down afterward. Hamstring, hip flexor, quad, and calf stretches after skiing, when muscles are warm. Five to ten minutes daily significantly reduces chronic tightness accumulating into injury.
• Listen to fatigue signals. A tired skier skiing technical terrain makes the mistakes that cause injury. If you're exhausted on day five of a run, take a cruising run or an early finish rather than pushing the off-piste in poor visibility.

The difference between a physio appointment in week eight and finishing a season without significant injury is usually made in weeks one to four.

A note on mental health

Season life can be isolating in ways that don't look like isolation from the outside — surrounded by people, always busy, but far from existing support networks, in a culture where stress and homesickness are rarely named. A separate article covers this in more detail. If you're struggling, the cabin pressure phenomenon (everything accelerated and amplified in a small resort community) is well-documented. Getting outdoors beyond the ski area, keeping contact with people at home, and naming what's happening to someone you trust are all practical starting points.
