why do you feel dizzy after exercising

Pushing yourself when you're exercising can help you see the results you want. But sometimes, overexerting yourself, not staying hydrated or exercising in the heat can lead to dangerous repercussions, particularly if your workout makes you feel dizzy, nauseous or faint. By understanding your risk factors for feeling dizzy after a workout, you can prevent the feeling from ruining a good session at the gym. However, if symptoms persist, see your doctor. Dizziness after a workout can have a variety of causes. One of the common causes of feeling faint after a workout is simply overexerting yourself. Pushing your body too hard can result in your heart working too hard and not getting enough blood to your head. You may also feel dizzy if you haven't been hydrating your body during exercise, or have been exercising in the heat. As part of the cooling response, the blood vessels throughout your body dilate. The dilation of the blood vessels in your brain can lead to dizziness. Dizziness may also be the result of exercising on a continual motion machine, such as an elliptical or a treadmill.

Upon stepping off the machine, you may experience vertigo, or the sensation you're still in motion when you've stopped. When you consult with your healthcare practitioner about your post-workout dizziness, she will likely evaluate your risk factors to determine the cause of your dizziness. Being overweight or out of shape can lead to dizziness, as can exercising in warm environments, being dehydrated and suffering from chronic benign paroxysmal positional vertigo. If you feel dizzy while exercising, stop immediately. Continuing to exercise while feeling faint could lead to tripping, falling and injuries. Take a break. You may find it helpful to sit down with your head between your knees as you restore blood flow to the head. If you feel dizzy while exercising on a machine, hold tightly to the rails and slow your pace until it's safe to get off. If you're away from home when you feel dizzy, wait until the feeling passes before trying to drive. Preventing a dizzy spell can help you avoid a workout that's cut short by light-headedness or a longer recovery than necessary.

By allowing your body to properly warm up to strenuous exercise, you give your heart time to adjust to the change in the need for blood to your muscles. Proper hydration -- to the tune of 7 - 10 ounces for every 10 to 20 minutes of exercise -- and exercising inside when it's above 90 degrees Fahrenheit, can help you avoid dizziness from heat and dehydration. Finally, if you constantly have issues with benign paroxysmal positional vertigo, talk to your doctor about exercises that can help improve your balance and exercise with a friend who can help you in the event of a dizzy spell.
After you finish a particularly strenuous exercise session, it's not uncommon to experience a feeling of lightheadedness or dizziness. Symptoms may include feeling as if you are going to faint, weakness or a perception that the room is spinning. Although this condition is not always cause for concern, lightheadedness can make you feel unstable and unsteady. You can take steps to eliminate exercise-related lightheadedness by increasing the amount of oxygen to your tissues.

Think of your body like a car. Just as your car requires gas to run, your body requires its own kind of fuel in the form of the foods you eat. When you exercise, your body uses energy stored in your tissues to enable you to exercise. When these energy stores run low, you might experience lightheadedness or dizziness. Always make sure you have БfuelБ in your body before exercising. A good way to accomplish this is to eat a 200-calorie snack 30 minutes to one hour before exercising. Examples include half a peanut butter sandwich, cereal and milk or a banana and juice. These foods contain carbohydrates, which are your bodyБs chief energy source. Some medications, including those used to treat blood pressure, can contribute to lightheadedness after exercising. Read the information labels or pamphlets associated with your medications for listed side effects such as dizziness or fainting. Discuss with your physician how you can minimize the effects of these medications while exercising.

When you exercise, your heart works harder to pump needed blood to your muscles. This enlarges your blood vessels, allowing them to compensate for the added blood flow. When you cease exercising, your heart may start beating more slowly, but your blood vessels may have not yet caught up. Because of the sudden decrease in circulating blood, your blood pressure can drop. This can lead to feelings of lightheadedness or dizziness. This can be a normal occurrence and typically does not indicate cause for concern. If you do get lightheaded after your exercise session, lie down and keep your head above your heart, which encourages blood flow to the body. If you did not cool down -- performing activities to lower your heart rate --- after your exercise session, you should do this at your next exercise session. However, if your symptoms continue, see your physician, who can evaluate your symptoms and help to determine if your lightheadedness after exercising is the sign of a more serious condition.
