does coughing burn calories?
Coughing, often referred to as a 'non-exercise activity thermogenesis' (NEAT), is a physiological response involved in protecting the respiratory system. The act of coughing causes the diaphragm and other accessory muscles to contract,expelling air from the lungs with a forceful burst of pressure, dislodging any obstructions or excess secretions. Although coughing is generally not categorized as a vigorous physical activity, it does require energy and thus contributes to a minimal calorie expenditure.
In terms of caloric expenditure, a study published in the Journal of Applied Physiology suggests that coughing can increase your metabolic rate by up to 20% for a short period of time, equivalent to burning an extra 5 to 10 calories per cough. However, the exact number of calories burned during a coughing episode can vary depending on factors such as the intensity of the cough (deep vs. shallow), its duration, individual differences in metabolism, body composition, and underlying health conditions.
While coughing may contribute a minimal amount of calories, it is important to note that this activity is far from the intense physical efforts required for activities such as running or weightlifting. Therefore, coughing does not significantly impact weight management or contribute to significant caloric deficits. Additionally, coughing has several other potential health benefits, including improved airway clearance, strengthened abdominal muscles, and relief from throat irritation, making it a useful behavior尽管它不直接影响体重管理.
So, while coughing may burn a trivial number of calories, its overall impact on metabolism and health is quite minor. For those interested inweight loss or overall fitness, regular exercise and a balanced diet are more appropriate and effective methods of achieving their goals.
