Systolic pressure went up an average of about 4 points, and diastolic, 3 points, in a study of middle-aged women who hadn’t gone to the bathroom for at least 3 hours. Men and women of different ages saw similar effects. High blood pressure becomes more likely as you age, so you need to get accurate readings. An empty bladder could be one way to help do that.

Ingredients like pseudoephedrine and phenylephrine can narrow your blood vessels. That means the same amount of blood has to squeeze through a smaller space, like a crowd pushing through a hallway. These drugs can also make blood pressure medications less effective. Your doctor or pharmacist can help you choose over-the-counter products for sinus problems and colds that are safer if you have high blood pressure.
