How many times a day is deep breathing exercise rec./day? What if you have work and school? I still need to keep my heart rate down. Advice please?

NoResearch, Answers: Deep breathing recommended by some, but the actual issue is relaxation, breathing, yoga, day dreaming (also called self-hypnosis), etc. Whatever works for you. People promote simplistic stuff which may, sort-of, help some (looking for mass market) yet rarely optimal for anybody. The bigger issue: reactions to life driving anger, frustration, fear, both external & especially internal (subconscious). ...Read more

What are the consequences for decreased heart rate that varies with respiration?

What are the consequences for decreased heart rate that varies with respiration?

Probably nothing: Heart rate varies with respiration normally. It is usually not sensible however. A low heart rate may be a normal occurrence in a conditioned person, however if the low heart rate causes fatigue, dizziness or passing out episodes, it needs to be evaluated. Usually, a treadmill stress test is done to see if the heart rate responds appropriately, if not, the person may need a pacemaker. ...Read more

What position would have a higher heart rate and breathing rate and why?

What position would have a higher heart rate and breathing rate and why?

Standing erect: When you lie or sit, your body doesn't have to fight gravity to get blood to your head. When you stand up, it does, and heart rate rises and leg blood vessels tighten to maintain blood flow to your brain. Breathing is less affected. If you have heart failure, breathing and heart rate may rise upon lying down since more blood returns to the heart than it can handle and it backs up into the lungs. ...Read more
