While I'm not going to get into the argument whether pharma companies want to keep people sick to sell drugs, there was an interesting item at the AADE conference to help patients lower their blood pressure--without drugs.
It's called Resperate and claims to be the only non-drug solution to high blood pressure available as an over the counter treatment to lower blood pressure.
Resp@rate as you can see from the photo is a device that trains you to do therapeutic breathing exercises to slow your breathing so that you your breath intake from 14 to 19 breaths per minute--down to what they call a "therapeutic zone"--just under 10 breaths/minute. The physiological result is muscles surrounding the small blood vessels in your body relax and dilate; blood flows more freely and pressure lowers.
The company says practicing 15 minutes, 3 to 4 times/week can create a significant all-day reduction in blood pressure. I don't endorse products, especially when I haven't tried them, as I don't have high blood pressure, but it seems worth investigating if you do.
Of course doing any relaxation technique like meditation or yoga, or right now just slowing down your breathing and taking deeper breaths likely creates a similar effect (including getting the anger out of your life). The trouble with slowing your breath sans device is it's easy to get distracted, but I have done meditation for decades and can attest to the benefits at slowing breathing and clearing the head and taking a break to recharge--and look mom, "no drugs."
