This is how i counter by anxiety and bp
i) do not allow your mind to consistently dwell on past /recent incidents. this may draw much blood to your brain and your heart may have to pump stronger.Instead, live and feel each moment with all your senses...i.e while driving, do you smell the distinct aroma in your car, can you feel the tires hitting occasional pebbles on the road, do you notice the pedestrians and other drivers on the road, notice the swaying leaves and branches, notice the birds circling above....
ii)while you are sitting,standing or lying, try noticing that some muscles in your limbs actually remain tensed..it will take a while to notice or come to a realization of it..feel and allow your limbs to relax and always remember to deliberately relax all your muscles..this helps the most to reduce bp.
iii) when you sleeping, try sleeping in the corpse pose...
you'd feel the difference in the morning..try googling for "yoga corpse".
iv) go for brisk walks..the docs are correct on this..and while you are on it...do not work you mind...instead awaken all your senses and embrace the joy of walking and being alive...working your muscles improves blood circulation and faraway cells will soon stop asking for more quota of blood,nutrients or oxygen..
v) be active at your workplace/home or whatever you do...do not delegate if you have the time to work it out yourself.
vii) fruits , milk and vsop did help me a lot too. not related to bp, but avoid processed/gm food , go natural.
viii) notice your breathing pattern..do not breath shallow(most in later years do it only to the level of thorax unconsciously).Make it a habit to inhale deep drawing more oxygen and exhale out more of CO2.. this also helps with metabolism to keep you lean and cells more energy efficient( less of glucose in bloodstream). this may explain why smokers (deliberately inhaling deeply) put on weight upon quitting...
vi) realize the ultimate truth...all problems vanish when you die ...which means, whatever problems you are seeing now are only a projection of your perspective in current circumstances and by shifting your perspective you can face or solve the problems in a much relaxed manner..
