Dizziness and blurred vision after strenuous exercise is a physiological phenomenon, as exercise can lead to an increase in heart rate and blood pressure, and for people who do not exercise regularly, there may be a lack of blood supply to the brain, so it is advisable to rest and observe if the symptoms persist, and if they do, consider seeking medical attention. If it gradually subsides after rest, there is no cause for concern. In future, care needs to be taken to readjust the amount of exercise and ensure gradual exercise to give the body sufficient time to adapt.
