High blood pressure

[JinglingAllTheWay]

Anyone know what can cause it?

Can things e.g. Stress raise the higher and lower reading??

How can it be naturally lowered?

Argh. Did that wrong

Treatment

Causes

Stress can certainly cause it.
Exercise is good (after taking medival advice)

sorry typo above should be 'medical'

Wondering what medieval advice on exercise would be? Jousting, perhaps...
