- Standing up too fast. It takes additional effort for your heart to pump blood through your body when you stand up, compared to when you lie down. In fact, your blood pressure naturally changes based on your position in order to maintain homeostasis, a state of balance that allows your body's many systems to function properly.
- Overheating and dehydration. If you don't drink enough water, especially when it's hot out, you can easily overheat and get dehydrated. When the temperature of your environment increases, your blood pressure naturally decreases, leading to feelings of dizziness and lightheadedness.
- Alcohol consumption. Alcohol can damage and narrow your blood vessels, decreasing blood flow and making your body work harder to regulate blood pressure.
- Vigorous exercise. As you exercise, your muscles encourage blood flow to your heart. When you rest, your blood tends to rush back to your extremities. This rush of blood, coupled with the exertion on your lungs, means you may feel a little dizzy when standing up or moving after exercise.
