Feel Tired and Euphoric

Exercise can cause both fatigue and euphoria due to various physiological and psychological factors.

Fatigue:

1. Muscle exhaustion: Prolonged physical activity leads to muscle fatigue, which is caused by the depletion of energy stores, such as glycogen and ATP, and the accumulation of lactic acid. This can make you feel tired and weak.

1. Cardiovascular strain: Intense exercise can increase heart rate and blood pressure, which can lead to cardiovascular strain and fatigue.

1. Hormonal changes: Exercise can cause changes in hormone levels, including the increase in cortisol and adrenaline, which can contribute to feelings of fatigue.

Euphoria:

1. Endorphins: Exercise can trigger the release of endorphins, which are natural painkillers that can also produce feelings of euphoria and well-being.

1. Dopamine: Physical activity can increase dopamine levels in the brain, which can lead to feelings of pleasure and reward.

1. Serotonin: Exercise can also increase serotonin levels, which can help regulate mood and reduce stress, leading to feelings of euphoria.

1. Self-esteem: Regular exercise can boost self-esteem and confidence, which can contribute to feelings of euphoria and overall well-being.

1. Social connections: Exercising with others can provide social support and a sense of community, which can also contribute to feelings of euphoria.

It's important to note that the intensity and duration of exercise can impact the levels of fatigue and euphoria experienced. Generally, high-intensity exercise will lead to greater fatigue, while lower-intensity exercise may result in less fatigue and more euphoria. Additionally, individual differences in physiology, psychology, and personal preferences can also influence the experience of fatigue and euphoria during and after exercise.
