Elevated cortisol levels
One of the adverse side effects of cardio is hormonal issues. Too many aerobic workouts put your body in a state of constant stress. This leads to the release of high amounts of cortisol. It disrupts the functioning of the thyroid gland, produces less testosterone, and store more belly fat.
Fatigue & sleep disruption
During overtraining, your sympathetic nervous system runs in overdrive, making it impossible for you to sleep naturally. You constantly experience fatigue, disrupted sleep, and fatigue-related disease in your central nervous system.
Loss of muscle & strength
During too much cardio without adequate strength training, your system will use protein from lean muscle tissue. During this catabolic phase, your basal metabolic rate decreases significantly, and your overall power and strength will also be affected.
Weak immune systems
Continuous exhaustion of energy supply deprives immune cells of important recovery time. Unregulated overtraining compromises immune system defences and increases the risk of catching infections in the upper respiratory tract, some viruses, and chronic inflammation.
Risk of repeated injuries
Constant cardio exposes the joints, tendons, and bones to overuse injuries without sufficient downtime. Symptoms such as chronic joint pain, stress fractures, or tendinitis are some of the adverse side effects of cardio.
