1. Not getting enough sleep
When you don't get enough sleep, your body releases more cortisol and adrenaline, which can cause stress and fatigue. In addition, high-intensity exercise can increase cortisol levels, causing a prolonged state of high stress and reducing the body's ability to heal itself.
2. Dehydration
Dehydration is one of the causes of fatigue.
Along with that, sweating during exercise will also cause the body to lose water and sodium and potassium. That is the reason why the body is more tired after exercise.
3. Cut down on too much starch
If you are on a low-carb diet, chances are you will not have enough carbohydrates to fuel your exercise.
Although your body can use protein and fat for energy, they cannot replace carbohydrates. Therefore, when you are on a low-carb diet after exercising, you will often feel more tired.
4. Lack of rest and recovery time
If you overtrain, your body is more susceptible to stress and injury. Overtraining without adequate rest causes stress, which also reduces the body's ability to heal itself.
Experts advise that after exercising, especially heavy exercise, take time to let your body rest or at least get enough sleep.
