3 unexpected reasons why your body feels tired after exercise

Common causes of post-workout fatigue include dehydration, lack of sleep, or poor diet, which is especially common in dieters. However, there are other less-expected causes that can also lead to extreme fatigue, even exhaustion, after a workout, according to Verywell Health (USA).

Overtraining causes the body to fall into a state of prolonged fatigue, increasing the risk of injury.

These causes include:

Central nervous system fatigue

Central nervous system fatigue is a condition in which the nervous system’s ability to control muscles is reduced. This results in impaired exercise performance and a generalized state of fatigue. Unlike normal muscle fatigue, which occurs in a specific area, central nervous system fatigue affects the entire body.

Neurotransmitters such as serotonin and dopamine play a key role in this process. When they are out of balance, motor skills and mental state are impaired. People who do long-term endurance training are prone to this phenomenon due to the stress of prolonged exercise.

Fatigue due to cognitive overload

If a person experiences a state of having to think a lot and think at a high level before exercising, the body will be more easily tired. This is because a tired mind also affects exercise performance, causing the body's endurance to decrease during exercise.

Overtraining Syndrome

Overtraining syndrome occurs when a person trains at an intensity and frequency that exceeds the body's ability to recover. The result is reduced performance and chronic fatigue. Symptoms include muscle pain lasting for weeks, irritability, insomnia, and weakened immune systems.

Recovery requires several days of rest and a revised workout plan. Regular exercisers and professional athletes should monitor their exercise load and ensure adequate rest to avoid this condition, according to Verywell Health .
