Potassium in an essential mineral needed for your body to function. The brain, heart and muscles are especially susceptible to the effects of high or low potassium. You can lose potassium through urine, sweat and waste. Potassium is found in your diet in fruits, vegetables, milk and most other foods. Persistently high or low potassium levels can be a sign of an underlying medical condition and require treatment by your doctor.
Step 1
Drink a sports drink containing potassium to replenish potassium and other electrolytes lost through sweat. This is especially important when being active for extended times or in hot environments. Once you are thirsty, you are already dehydrated. Begin drinking when you start being physically active.
Step 2
Avoid using diuretics that deplete potassium by expelling large amounts in the urine. If you are on a prescription diuretic under the direction of your doctor, ask him for specific instructions regarding potassium intake.
Step 3
Eat foods rich in potassium, including fruits such as bananas, vegetables and milk. Although it is rare to have potassium deficiency due to low amounts in your diet, you can still benefit from these healthy foods.
Step 4
Always take potassium supplements according to label directions. Taking large amounts of potassium from supplements is a medical emergency that can decrease the ability of your heart to pump blood.
