Dizziness and nausea can be relieved by stopping the exercise immediately, resting appropriately and replenishing water in time. Dizziness and nausea in excessive exercise is mainly due to the fact that during exercise most of the blood is allocated to the limbs to adapt to the needs of the movement, resulting in less blood supply allocated to the head and insufficient cerebral blood supply, which can lead to dizziness and nausea and other symptoms. If the usual basal blood pressure is low, coupled with more sweating after exercise, the blood volume will be relatively reduced, which will lead to a reduction in blood perfusion in the head, affecting the blood supply, can also lead to dizziness and nausea. The best thing to do in this situation is to stop exercising immediately, take proper rest, and replenish water or supplement sports drinks in time. Usually when you exercise, you should pay attention to avoid sudden and intense, a large number of exercise, should be gradual, according to their own situation, according to their own strength. If you can not effectively relieve the symptoms of dizziness and nausea through the above ways, it is recommended to seek medical advice in time, under the guidance of the doctor to improve the symptoms, to rule out the factors of the disease, so as to avoid triggering adverse consequences.
