Loss of consciousness during exercise can be a real shock. However, this is not always a signal of a serious illness. Perhaps the training schedule was not drawn up correctly or the load did not correspond to physical capabilities. Sometimes you just need to make small adjustments so that this situation never happens again.
Syncope
Fainting, or syncope, occurs when the brain is deficient in oxygen from the blood. The brain needs a continuous supply of oxygen. If, for some reason, cerebral circulation is impaired, the person experiences symptoms preceding loss of consciousness. This is dizziness, disorientation, darkening in the eyes, and fainting is the extreme point. Of course, consciousness returns after a few seconds, but the general condition can be restored within 15-30 minutes.
Causes of loss of consciousness during exercise
There are several situations that can lead to loss of consciousness. One of them is dehydration of the body. If the load during exercise is high, a person loses a lot of water through sweat. Dehydration leads to a decrease in blood pressure. As a result, symptoms such as dizziness, weakness and fainting occur. Therefore, fitness experts recommend that you always have a bottle of still water with you at room temperature. Indeed, by the time a person begins to feel thirsty, he is already 20% dehydrated. Also of great importance is the environment in which the training takes place. Stuffiness, poor ventilation and large crowds can cause a lack of oxygen. In such an atmosphere, even with a light load, loss of consciousness can occur.
A high level of physical activity, especially with irregular training, leads to overwork of the body. With an unreasonably sharp increase in the load, the heart rate rises significantly, which means that the cardiovascular system is working to wear and tear. This pace makes you breathe more often, sometimes too often. A condition called pulmonary hyperventilation occurs. Substances such as oxygen and carbon dioxide are distributed throughout the body through the blood only in a partially optimized form. And it can also lead to loss of consciousness.
Long-term or intense exercise can lower blood sugar levels. Hypogleukemia occurs. Like all other organs of life, the brain also needs sugar. With a deficiency of this substance, the normal functioning of the brain is disrupted and a state close to fainting may occur.
What to do at the first sign of fainting
If during exercise you feel dizzy, nauseous, sweaty, blurred vision, or a tingling sensation in your lips and fingertips, these may be symptoms that precede fainting. You need to pull yourself together and do everything to avoid injury or injury from a fall. First of all, call for help. Move away from the equipment as much as possible. Lie on the floor and do not move. Do not resume training before consulting your doctor.
