Feeling short of breath after climbing one or two flights of stairs is a common occurrence in people of all ages and physical fitness levels.
The question arises whether this is a normal reaction of the body to stress or a signal that requires medical examination.
Experts point out that although short-term shortness of breath during exertion is usually not dangerous, there are situations in which it requires extra attention, writes HuffPost.
Physiological reaction to exertion
Climbing stairs is an intense physical activity that places significantly more strain on the body than walking on a flat surface, reports Net.hr.
Research shows that this activity requires up to nine times more energy than sitting. During physical exertion, the metabolic need for oxygen increases, which leads to increased work of the heart and lungs to ensure an adequate supply of oxygen to the muscles.
"The feeling of shortness of breath after climbing stairs is a normal physiological response. The body is put under greater demands, the work is more intense, and therefore the need for oxygen," explained Katherine Polgirs, a doctor of family and sports medicine.
Karl Erickson, a sports medicine expert at the Mayo Clinic, agrees, adding that such a reaction is expected.
"Essentially, you're lifting your own body mass against gravity. Each step is biomechanically similar to a squat or lunge, which is significantly more strenuous than regular walking," he adds.
The intensity of shortness of breath depends on a number of factors, from climbing speed to carrying additional weight.
When is shortness of breath a cause for concern?
While shortness of breath is an expected reaction, it's crucial to recognize when it's beyond the normal physiological response. If it takes you up to two minutes to normalize your breathing and you feel fine afterward, there's probably nothing to worry about. However, experts warn of a few signs that warrant caution.
The first warning sign is if shortness of breath is a new occurrence or if its intensity worsens over time.
"The most important thing is not to jump to conclusions about a serious illness, but you also shouldn't simply attribute the symptom to poor physical condition," Dr. Polgirs points out.
A sudden change in the ability to endure exertion is something that doctors take seriously.
Another important indicator is the time required for recovery.
"Recovery time is a reliable indicator. It's normal for breathing to be rapid for a minute or two, but if the elevated breathing rate lasts longer than three minutes, it can be concerning," says Erikson.
Also, shortness of breath should never be ignored if it is accompanied by other symptoms such as chest pain, headache, vision changes, dizziness, palpitations, nausea, or swelling of the feet and ankles. Such symptoms may indicate more serious health problems, including heart and lung diseases (such as asthma, COPD, or heart failure), anemia, or thyroid disease.
Ways to improve physical endurance
If you want to make climbing stairs less tiring, the solution, provided there are no medical obstacles, is regular physical activity.
"The body adapts to the demands you place on it. So if you practice climbing stairs regularly, it will become easier for you," explains Erikson.
Strengthening your lower body muscles is key to making it easier to climb stairs. Exercises like squats and lunges will increase your strength and endurance.
Additionally, improving your overall cardiovascular fitness through activities such as brisk walking, cycling, or swimming will also help reduce fatigue. At least 150 minutes of moderate aerobic activity per week is recommended.
Dr. Polgirs advises a gradual approach. There's no need to immediately put yourself through a major effort like climbing the fifth floor. Instead, build fitness gradually and sustainably, whether through more frequent walks, gardening, or consciously choosing the stairs over the elevator.
If you notice that your shortness of breath is getting worse, lasts for an unusually long time, or is accompanied by other worrisome symptoms, it is recommended that you seek medical advice.
