An asthma diagnosis doesn't mean you have to give up sports – quite the opposite. Regular physical activity can improve asthma control, strengthen lung function, and increase quality of life. Many top athletes, including Olympic champions, live with asthma and achieve peak performance.

The paradox: Exercise can trigger asthma symptoms (exercise-induced asthma), but regular exercise improves asthma control in the long term. The key lies in the 'how' – in choosing the right activity, warming up, managing triggers, and using preventative medication.

This guide is for people diagnosed with asthma who want to stay or become active. It does not replace medical advice or individually tailored therapy. However, it provides guidance on how to exercise safely and effectively with asthma.

The most important message: Asthma is no reason to stay on the couch. With the right knowledge and management, you can participate in almost any sport. It requires a little more planning and attention than for people without asthma, but the benefits far outweigh the limitations.

Speak to your doctor before starting a new exercise program, especially if your asthma is not well controlled. Optimized baseline therapy is the foundation for safe exercise.

Exercise-induced asthma (EIA), or more precisely, exercise-induced bronchoconstriction (EIB), refers to the narrowing of the airways triggered by physical exertion. It affects 70-90 percent of people with asthma, but also about 10 percent of the general population without other asthma symptoms.

Symptoms typically appear 5-15 minutes after the start of exertion or shortly after it ends: shortness of breath, chest tightness, coughing, wheezing. Some may experience only a persistent cough after exercise or an unusually long recovery time.

The cause: During strenuous breathing, the air is not sufficiently warmed and humidified before it reaches the bronchi. The cold, dry air irritates the sensitive mucous membranes, which react with swelling and mucus production. The smooth muscles of the bronchi contract – the airways narrow.

Risk factors for EIB: Cold, dry air (winter sports, indoor swimming pools with high chlorination). High-intensity and long-lasting training. Mouth breathing. Poor air quality (smog, pollen). Respiratory infections. Poorly controlled asthma.

The diagnosis is made by a lung function test before and after standardized exercise. A decrease in FEV1 (forced expiratory volume in one second) of more than 10 percent is considered positive.

EIB is no reason to avoid exercise. With the right strategies, most affected individuals can train without symptoms.

In principle, people with asthma can participate in almost any sport. However, some are more suitable than others, especially if EIB is a problem.

Especially suitable: Swimming is considered ideal – the warm, moist air above the water is less irritating to the airways. The horizontal position can make coughing up mucus easier. Caution: Heavily chlorinated indoor pools can cause problems for some people. Hiking, moderate cycling, yoga, Pilates, strength training – activities with moderate, steady exertion and rest periods.

Caution is advised: Endurance sports with high, sustained intensity (running, cycling) require good management. Winter sports in cold air are a known trigger. Team sports with sprints and high intensity can be challenging, but are possible.

Potentially problematic: Diving requires special caution and medical clearance due to the pressure changes. Extreme endurance under difficult conditions (ultramarathons, high-altitude mountaineering) is more demanding.

No absolute prohibitions: The list of top athletes with asthma includes long-distance runners, cyclists, and cross-country skiers – sports that would actually seem 'unfavorable'. With individually tailored management, much is possible.

Recommendation: Start with asthma-friendly sports, optimize your management, and then expand once you have good control. Listen to your body and work together with your doctor.

A thorough, structured warm-up is particularly important for asthmatics – it can significantly reduce or even prevent EIB symptoms.

The phenomenon of the 'refractory period': If you warm up properly and thereby provoke mild EIB symptoms, a period of 30-60 minutes follows in which the airways are less sensitive. This 'protective phase' allows for more intensive training with fewer symptoms.

Here's what an optimal warm-up looks like: At least 15-20 minutes, preferably longer. Start with very low intensity and increase gradually. Include a few short intervals of high intensity (30 seconds) to take advantage of the refractory period. Then let the intensity drop again before the actual workout begins.

Example for runners: 5 minutes of slow walking, 5 minutes of light jogging, 3-4 short sprints (15-30 seconds fast, then slow again), 5 minutes of light jogging. Only then does the actual training or competition begin.

Breathing during warm-up: Breathe through your nose as much as possible. This warms and humidifies the air. In cold weather: Wear a face mask or buff over your mouth and nose.

Skipping the warm-up is the most common mistake made by people with asthma. It may feel like a waste of time, but it's the most effective non-drug protection against EIB (excessive asthma). Make it a firm part of every workout.

Asthma triggers vary from person to person. Identifying your personal triggers is crucial for successful training.

Cold, dry air is the most common trigger for EIB (Excessive Illness). In winter or in air-conditioned rooms: wear a mask or buff to pre-warm the air. Alternatively: train indoors in cold weather.

Pay attention to air quality: On days with high ozone or particulate matter pollution, it's best to train indoors or reduce the intensity. Air quality is worse in busy areas (main roads) – choose parks or quieter routes.

Pollen: During pollen season, allergies can worsen asthma. Check pollen forecasts, exercise in the morning or after rain (less pollen), and shower and change your clothes afterward.

Infections: Asthma is often more unstable during respiratory infections. Avoid or reduce intensive training during and shortly after infections. Only resume training once fully recovered.

Chlorine in indoor swimming pools can irritate the respiratory tract in some people, although swimming is generally good for them. Choose well-ventilated pools; if you experience problems, try swimming outdoors.

Emotional stress and laughter can trigger symptoms in some people with asthma. Stress management is also asthma management.

Keep a symptom diary: When do problems occur? What are the prevailing conditions? Over time, you will recognize patterns and be able to take targeted preventative measures.

This section provides an overview – you should discuss the specific therapy with your doctor.

The basic therapy must be right: If your asthma is poorly controlled overall, EIB will also be more difficult to manage. Optimized long-term medication (usually an inhaled corticosteroid) is the foundation.

Short-acting beta-2 agonists (SABA, e.g., salbutamol): The classic choice for premedication. Inhaled 15-30 minutes before training, they provide protection for 2-4 hours. Not ideal for long-term use, but very effective in specific situations.

Long-acting beta-2 agonists (LABA): For frequent, regular training, daily intake may be more beneficial than situational use of short-acting beta-2 agonists (SABA). Always in combination with an inhaled corticosteroid.

Leukotriene antagonists (e.g., Montelukast): Can be helpful as an adjunct, especially in cases of combined asthma and allergies.

Always have your emergency inhaler with you: No matter how well your asthma is controlled, take your reliever inhaler to every workout. Keep it in a belt pouch, in the car, within easy reach. There's no excuse not to have it with you.

If symptoms occur during training: Stop the activity, inhale your rescue inhaler, and wait 15-20 minutes. If the symptoms do not subside or worsen: Stop training and seek medical help if necessary.

Doping regulations must be observed: Some asthma medications are on the doping list. For competitive athletes: Apply for a Therapeutic Use Exemption (TUE).

The way you breathe significantly affects the strain on your airways. Breathing exercises can reduce EIB (excessive bronchial inflation) and improve asthma control.

Nasal breathing: The nose filters, warms, and humidifies the incoming air. All of this reduces irritation of the bronchi. Train yourself to breathe through your nose as much as possible – even during exercise. This requires lower intensity at first, but in the long run, it builds CO₂ tolerance and breathing efficiency.

Diaphragmatic breathing: Deep abdominal breathing instead of shallow chest breathing. The lungs fill more efficiently, and the respiratory muscles work more relaxed. Practice diaphragmatic breathing in a relaxed state until it becomes automatic.

Slow exhalation: At the onset of symptoms, consciously slowing and controlling your exhalation can help. Don't force it, exhale calmly – like through a straw.

Pursed-lip breathing: A technique for shortness of breath – exhale through pursed lips, as if you were blowing out a candle, but very slowly. This creates a slight back pressure that keeps the airways open.

Buteyko Method: A breathing technique that relies on reduced lung volume and increased CO₂ tolerance. Studies show improvements in asthma symptoms and reduced medication requirements. Not a replacement for medication, but worth considering as a supplement.

Respiratory muscle training: Devices like the PowerBreathe train the respiratory muscles against resistance. This can improve breathing efficiency and reduce the feeling of shortness of breath.

Environmental conditions have a significant impact on EIB. Adjustments depending on the weather and location make all the difference.

Cold weather: The biggest trigger for many. Strategies: Cover your mouth and nose (mask, buff, neck warmer), breathe through your nose, reduce intensity, use indoor alternatives. Below 0°C: Be especially careful or train indoors.

Hot, humid air: Actually, often better for asthmatics because the air is already humid. But: Heat itself can be stressful, and high temperatures are often accompanied by poor air quality.

High humidity: Generally better for the respiratory system than dry air. Swimming in warm indoor pools benefits from this.

Altitude: At high altitudes, the air is colder and drier. Asthmatics should be especially careful when spending time at high altitudes (mountaineering, skiing) and acclimatize slowly.

Urban environment: Traffic, industry, and smog negatively impact air quality. Prefer green parks to main roads for outdoor sports. Use air quality apps and exercise indoors on bad days.

Indoor swimming pools: The warm, humid air is good, but chlorine compounds can be irritating. Choose well-ventilated pools, prefer outdoor pools in summer, and look for alternatives if problems arise.

Indoor training: More controlled conditions (temperature, humidity, air quality). Ensure good ventilation in sports halls – dust can be a problem.

Regular exercise improves asthma control in the long term – this is not wishful thinking, but has been proven by studies.

Improved lung function: Endurance training strengthens the respiratory muscles and improves ventilation efficiency. Lung capacity can increase, and the airways remain more open.

Reduced inflammation: Regular moderate exercise has anti-inflammatory effects throughout the body – including the respiratory tract. This can positively influence the underlying causes of asthma.

Improved fitness, less shortness of breath: As your fitness increases, your breathing rate decreases at the same level of exertion. You're less short of breath, not because your asthma has disappeared, but because you're fitter.

Weight management: Being overweight worsens asthma. Exercise helps with weight management and thus reduces a risk factor.

Psychological benefits: Chronic illnesses like asthma are often accompanied by anxiety – fear of attacks, fear of losing control. Regular, successful training builds self-confidence and reduces anxiety.

Reduced medication needs: Many asthmatics who exercise regularly report needing less rescue inhaler. Some can reduce their maintenance therapy in consultation with their doctor (not on their own!).

The initial hurdle is the biggest. Many asthmatics avoid exercise for fear of symptoms. This leads to a decline in fitness, worsening symptoms during exertion, and further avoidance – a vicious cycle. Exercise breaks this cycle.

Can I run marathons if I have asthma?

Yes, many people with asthma run marathons and longer distances. The prerequisites are: well-controlled asthma, individually tailored management, thorough warm-up, an emergency inhaler, and an understanding of your own limits. Gradually increase the distance and gain experience under different conditions.

Should I exercise if my asthma is not well controlled at the moment?

No. If you need your rescue inhaler more than twice a week, wake up at night because of asthma, or have constant symptoms, your asthma is not adequately controlled. First, optimize your basic therapy with your doctor, then resume training. Exercise with unstable asthma is risky.

What is the difference between asthma and poor fitness?

With poor fitness, you'll experience shortness of breath, but you won't have wheezing, chest tightness, or a persistent cough. Recovery after exercise is quick. With EIB (exertional bronchial asthma), typical asthma symptoms appear, often only after exertion, and they last longer. If you're unsure, have a lung function test.

Can exercise cure asthma?

No, asthma is a chronic condition that cannot be cured, but it can be very well controlled. Exercise improves control, reduces symptoms, and can lower the need for medication. However, the underlying hypersensitivity of the airways remains.

Is swimming really the best sport for asthmatics?

Swimming is often a good choice because of the warm, humid air. But the 'best' is individual. Some asthmatics react to chlorine. The best sport is the one you enjoy and where you can control your asthma. Try different activities.

What should I do if I develop symptoms despite premedication?

Stop the activity, use your emergency inhaler, and wait. If the symptoms subside, you may be able to continue at a reduced intensity. If they don't improve or worsen: stop training. In case of severe shortness of breath: call emergency services. Discuss recurring problems with your doctor – your preventative measures may need to be adjusted.

Should children with asthma participate in sports?

Absolutely! Sport is especially important for children with asthma, both for their physical and mental development. The same principles apply: warm-up, knowing triggers, having an emergency inhaler on hand, and pre-medication if necessary. Teachers and coaches should be informed. With well-controlled asthma, children can participate in regular school sports.

How do I explain my asthma to my coach or training partners?

Be open and factual. Explain that you have asthma, what that means (your airways are sensitive), that you have it under control, but that you need your inhaler in case of an emergency. Most people are understanding. It can be helpful if someone knows where your inhaler is in an emergency.

Can I exercise if I have a respiratory infection?

With mild cold symptoms (runny nose, slight sore throat), light exercise is often possible. If you have symptoms below the throat (cough, chest tightness, fever), you should take a break. Start again slowly after an infection. Infections can temporarily worsen asthma.

Which warning signs should I take seriously?

Symptoms that do not improve despite using a rescue inhaler. Worsening symptoms over several days. Waking up at night due to asthma. Needing to use a rescue inhaler more than twice a week. Blue lips or extreme shortness of breath: emergency, seek immediate medical attention.
