At first I didn't know, the health advicer just told me, anyway, thanks for ur advice!
IF your BP is that high u should get checked out. Reducing your salt-intake is a significant factor in lowering your BP. For example, don't eat those salty chips and all those extra salty snacks..just avoid adding salt that's not needed. If u are overweight, start exercising. Get checked out by a doctor. Of tell your parents. As long as your pulse rate goes.. Are u an athlete? Your pulse is below average but it's very common in athletes. High BP is really dangerous especially if it's already high at your age ( I am 14 and also have high BP and are on meds) I wish u all the best!!
