Activities that require deep, mindful, or intense breathing can help improve lung health. Here are some alternatives.
The human body needs oxygen to live, so you must keep the respiratory system in good condition. Strengthening lung health can be achieved through some care and exercises that increase the capacity of the lungs.
When you exercise, your heart and lungs are activated. The lungs oxygenate the body, initiate oxygen delivery to all cells, and remove carbon dioxide.
For its part, the heart is responsible for pumping oxygen to the muscles involved in exercise through the blood. This is how the body maintains energy, thanks to the combustion of certain nutrients in contact with oxygen, as explained in a publication by the European Lung Foundation.
Exercises that help strengthen lung health.
1. Yoga
Yoga is also a very beneficial discipline for lung health. This traditional activity helps you control your breath, bringing your body and mind into harmony.
More than physical yoga, it is advisable to practice pranayama, which is the primary breathing technique in yoga. This modality teaches breathing and develops lung capacity, which results in more endurance in physical activities.
• You should take long, deep breaths and exhale slowly.
• The ideal posture or asana to do pranayamas is the lotus pose. This requires being seated and with the spine straight, so that the air flows more easily.

2. Aerobic exercises
Performing aerobic exercises such as jogging, walking, running, or dancing can also be an excellent option to strengthen your lung health. In this way, you will help your heart rate increase and, therefore, you need more oxygen.
When the body is subjected to these aerobic activities, it demands more oxygen, so you must control your breathing and take all the air you need. This causes lung capacity to increase, as described in the specialized publications cited above.
Interval exercises are perfect for strengthening lung health, due to the degree of demand they represent. The body varies its oxygen demands according to the intensity of the exercise. Thus, it becomes necessary to take control of your breathing to keep you going.
• A simple interval exercise is jogging for four minutes and running for one.
• The idea is to do a certain amount of exercise at a moderate intensity and combine it immediately with a short period of high intensity.
• Repeat the cycle as many times as you can.

One of the main benefits of HIIT training - High-Intensity Interval Training - promotes fat burning, as detailed in a study published by the Journal of Obesity.

3. Breathing from the diaphragm
The way to breathe correctly is by using the diaphragm, so that the lungs expand and fill with oxygen. Not everyone is proficient in this type of breathing, but it can be done with practice.
According to a publication from the International University of Valencia, the technique for diaphragmatic breathing is as follows:
• Relax your upper body and put one hand on your abdomen.
• Take a deep breath through your nose, make your abdomen inflate, and then push the air out as slowly as possible.
• If when you exhale, the abdomen contracts, you are breathing correctly.
• Repeat the exercise five times and rest between each repetition. Try to do it as many times a day so that your body gets used to breathing the right way.

4. Blow for as long as possible
