The Impact of Cardio on Health: Understanding the Connection Between Cardio and High Cortisol

  • by

Cardiovascular exercise, or cardio for short, has been a staple in fitness routines for decades. From running on a treadmill to cycling outdoors, many people have turned to cardio as a way to improve their health and fitness levels. However, recent studies have shown that too much cardio can have negative effects on health, particularly when it comes to the stress hormone cortisol.

Cortisol is a hormone that is released by the adrenal glands in response to stress. It plays a vital role in the body’s fight or flight response, but when cortisol levels remain elevated for extended periods of time, it can lead to a host of health problems. High cortisol levels have been linked to weight gain, poor immune function, and even depression.

One of the primary ways that cardio can lead to high cortisol levels is through overtraining. When individuals engage in too much cardio or don’t allow their bodies enough time to recover between workouts, cortisol levels can become elevated. This can cause the body to enter a state of chronic stress, leading to a cascade of negative health effects.

In addition to overtraining, other factors can contribute to high cortisol levels during cardio exercise. For example, performing cardio first thing in the morning on an empty stomach can cause cortisol levels to spike. Similarly, performing cardio in a fasted state or engaging in high-intensity cardio workouts can also lead to elevated cortisol levels.

While it is important to stay active and engage in regular exercise, it is equally important to balance cardio workouts with other forms of exercise, such as strength training and yoga. This can help reduce the risk of overtraining and prevent the negative health effects associated with high cortisol levels.

In conclusion, cardio can be a valuable component of a healthy lifestyle, but it is important to understand the potential negative impacts on health, particularly when it comes to cortisol levels. Individuals should strive to balance their cardio workouts with other forms of exercise, allow for adequate recovery time, and listen to their bodies to prevent overtraining. By doing so, individuals can reap the benefits of cardio exercise without putting their health at risk.
