Regular exercise is praised as one of the most important aspects of a healthy and balanced lifestyle. Knowing how to exercise properly, however, is just as important as participating in a regular exercise regimen. It is also important not to overlook the smaller details of exercise, particularly if and when it is safe to drop the head below the level of your heart while you exercise.
Explanation
The body is conditioned to adapt to mildly high blood pooling and pressure in the blood vessels of the cranium. When you exercise, your blood pressure naturally increases in order to pump more blood and oxygen to the working muscles. Lowering your head below your heart will cause gravity to draw more blood toward the ground, into your head, causing a pooling of blood and elevated blood flow and pressure to the head. In rare cases, this rapid shift in the natural intracranial pressure, or pressure in the head, can cause severe, long-term health problems.
Complications
Some people may be more prone to incur problems than others when placing their head below their heart during exercise. Pregnant women, people with low or high blood pressure, and even people with conditions like eye diseases should avoid exercise positions that require lowering the head below the heart. Doing so may cause dizziness, light headedness, and may also cause fainting, which can lead to greater injury. In severe cases, hemorrhaging of blood vessels may even occur.
Modifications
If you participate in group fitness classes like aerobics or yoga, and are pregnant, have diabetes, or suffer from high blood pressure, inform your class instructor of your condition. She may suggest exercise modifications that will allow you to participate in the class, and can help you to avoid developing problems.
Whether or not you have special health conditions, be mindful of your heart rate and energy level during exercise. Regardless of health status, anyone can be prone to fainting from raising the head above the heart level too quickly during exercise, so raise your posture slowly if your head is below your heart's level.
Considerations
Talk with your physician before beginning a new exercise program. One exercise program is not necessarily suitable for all. Your physician can help you determine the safest and most beneficial exercises for your needs and health conditions.
