1. Stop running suddenly: On the treadmill, we usually stop running suddenly, which will lead to a sudden drop in blood pressure, which will lead to dizziness.
2. Lack of water: When exercising, people will sweat a lot, so the body will lose water. If you don't replenish water in time, you will feel tired and dizzy.
3. Hypoxia: Your body needs more oxygen to exercise when you exercise on the treadmill for a long time. If you can't get enough oxygen, your body will easily feel dizzy.
4. Excessive exercise: Exercise on the treadmill for a long time will consume a lot of energy and produce lactic acid, leading to fatigue and dizziness.
5. Air pollution in gymnasiums: Many gymnasiums are poorly ventilated, and toxic gases such as carbon dioxide in the air will affect your body and cause dizziness.
If you feel dizzy on the treadmill, you should stop immediately, let your body have a rest and drink some water to supplement your body's needs. Avoid stopping exercise suddenly, simply slow down your pace and let your body adapt to such changes. If you still feel dizzy, you should consider seeing a doctor to assess your health.
