@Sobeit - It sounds like you're already doing the right things for your circulation if you live a healthy lifestyle. It isn't hard to increase your circulation if you exercise at least 30 minutes every day. And you can break that up into 10 minute segments to increase blood flow. Short walks, jump rope, bike riding, deep breathing through yoga are all good options for busy people.
There are plenty more ideas but I'm sure your capillaries will thank you for upping your exercise and deep breathing!
