Low blood pressure readings after exercise

Written by: Dr. Rowena | Posted: May 04 2007

Q: I have noticed that 1 or 2 hours after strenuous aerobic exercise my BP readings are very low (90/65) and sometimes I feel very lethargic. Is this because of the water loss during exercise? Do I need to watch my sodium intake?

A: It is essential to maintain hydration with strenuous exercise. Keep in mind that sweat contains more than just water so you also lose electrolytes like sodium. Sports drinks are designed to help replace these losses.
