Smoking isn't part of a healthy lifestyle: nicotine constricts vessels and reduces flow. Your doctor simply had you stop so your body would resume normal healthy flow.rebel2011;439124 said:Blood flow has everything to do with how a body heals. That's why I had to stop smoking when I had a compound fracture to my lower leg. That's is why people with diabetes often get major infections in the feet and lower legs. If a part that is injured does not get enough blood your asking for trouble.
Diabetes is not "healthy" either. They have unhealthy blood flow - abnormally low in certain areas.
So both examples you give about blood flow point back to what I said: if you're healthy don't worry about it.
But increasing blood flow isn't going to do anything but work your heart and vessels. Cells won't receive any more nutrients because more blood than normal is flowing by them. Cells aren't ravenously hungry, hoping more blood will flow their way. They use a process of chemical balances. Normal blood flow is more than adequate. In an exaggerated example: if more blood flow means growth it must also mean you have to eat more.
But in reality, flowing the same blood past the same cells every minute versus every 90 seconds isn't going to make any difference.
