My blood pressure is 101 over 66 and my pulse is 68. I am a male, age 51 , non-smoker, weight is 155 lbs. and height is 5'5". I'm a healthy eater, and don't eat alot of meat or greasy foods. Mostly chicken, fresh fish and veggies. Very little salt added if any. I walk on a regular basis. Sometimes feeling tired and out of energy by end of day. I know I have low blood pressure and wanted to know if pressure should increase and if so, how does one increase blood pressure? does more exercise help? please advise
