What will happen to your blood circulatory when you do a headstand?

When you do a headstand, blood flow to the upper body, particularly the head and brain, increases due to gravity. This can enhance oxygen and nutrient delivery to the brain, potentially improving focus and clarity. However, it can also lead to increased pressure in the head and eyes, which may cause discomfort or headaches if held for too long. Overall, while beneficial in moderation, it's important to practice headstands safely to avoid strain.
