Detailed explanation-1: -Vasodilation is the widening of your blood vessels. It happens when smooth muscles found in the walls of arteries or large veins relax, allowing the blood vessels to become more open. This leads to an increase in blood flow through your blood vessels as well as a decrease in blood pressure.
Detailed explanation-2: -Vasodilation is a natural process that increases blood flow and decreases blood pressure. Vasodilation is mostly beneficial, as it helps deliver oxygen and nutrients throughout your body. But, vasodilation can be harmful in some cases, leading to severe hypotension (low blood pressure).
Detailed explanation-3: -Indeed, these arterioles are referred to as resistance vessels for they dominate the total peripheral resistance (because of their small size and large number) that controls mean blood pressure.
Detailed explanation-4: -Increase cardiovascular exercise. If you smoke, quit. Drink black or green tea. If you are anemic, take iron supplements or eat iron-rich food. Dry brush your body. Decrease stress. Include more omega-3 fatty acids in your diet. Wear compression socks and elevate your legs. 27-Oct-2020
