Excessive Exercise
Excessive exercise can cause lightheadedness or dizziness because the body is overexerting to strenuous activities. Post-workout dizziness is not a serious concern, as it only results from several factors, such as forgetting to breathe. Muscles consume too much oxygen when exercising. Breathing and heart rate increase to compensate for the flow of oxygenated blood in the muscles,
The brain may not receive sufficient oxygenated blood from the heart if a person doesn’t breathe during and after working out. As a result, dizziness may occur because there is insufficient oxygen in the brain. In addition, excessive exercise can cause lower blood sugar, leading to lightheadedness or fainting because the body uses more energy than usual.
The first 15 minutes of a workout are crucial for the body, as it uses the sugar in the muscles and bloodstream to provide strength. However, blood sugar level drops once it’s depleted. Sugar is one of the essential components for the brain to work properly. When starved of sugar, the body starts to feel dizzy, weak, and faint.
