Research from the early aughts looked into the instantaneous and long-term calming effects of breathing exercises like chanting a mantra and coherent breathing – a style of breathing which ...
Shortness of breath (SOB), known as dyspnea (in AmE) or dyspnoea (in BrE), is an uncomfortable feeling of not being able to breathe well enough. The American Thoracic Society defines it as "a subjective experience of breathing discomfort that consists of qualitatively distinct sensations that vary in intensity", and recommends evaluating dyspnea by assessing the intensity of its distinct ...
Since paroxysmal nocturnal dyspnea occurs mainly because of heart or lung problems, common risk factors include those that affect the function of the heart and lungs. Risk factors for cardiac diseases include high blood pressure, high cholesterol, diabetes, obesity, and a lifestyle lacking exercise and a healthy diet.
Reduced breathing effort (drug effects, brain stem lesion, extreme obesity) A decrease in the area of the lung available for gas exchange (such as in chronic bronchitis) Neuromuscular problems (Guillain–Barré syndrome, [2] motor neuron disease) Deformed (kyphoscoliosis), rigid (ankylosing spondylitis), or flail chest.

In other words, if you have nasal congestion and a scratchy or sore throat (like an uncomplicated cold), exercising might still be on the table, but if you have chest congestion, body aches and ...
Early symptoms of emphysema vary. They can include a cough (with or without sputum), wheezing, a fast breathing rate, breathlessness on exertion, and a feeling of tightness in the chest. There may be frequent cold or flu infections. [1] Other symptoms may include anxiety, depression, fatigue, sleep problems and weight loss.
Heavy breathing during exercise also provides cooling for the body. After some time the veins and capillaries dilate and cooling takes place more through the skin, so less heavy breathing is needed. The increase in the temperature of the skin can be felt at the same time as the "second wind" takes place.
The exact mechanisms behind exercise hyperpnea are not well understood, and some hypotheses are somewhat controversial. However, in addition to low oxygen, high carbon dioxide, and low pH levels, there appears to be a complex interplay of factors related to the nervous system and the respiratory centers of the brain that governs hyperpnea.
