When You Gotta Go - Full Bladder Linked to Heart Strain

The good news is that coffee drinking is back on the menu, if you don't overdo it. Think in terms of 4-6 cups a day. The bad news is that coffee, along with the other liquids you drink throughout the day, can put quite a strain on your bladder.
 
If you're tempted to hold it, don't.
 
A study at National Taiwan University showed that a full bladder is nothing to sneeze at, especially if you have any heart problems. Along with being uncomfortable, the stress of having a full bladder can increase your heart rate by an average of 9 beats per minute. That may not sound like a lot, but if you're overweight, smoke, or don't get a lot of exercise, your heart is already under strain.
 
How does needing to pee affect your heart? As your bladder expands, it puts pressure on your nervous system. Your body reacts in part by causing the veins and arteries of your heart to narrow, decreasing blood flow. This in turn forces your heart to pump harder, putting more stress on your heart, and boosting your risk of a possible heart attack.
 
What can you do? Don't wait for the pressure to build up. Stop at gas stations, restaurants or rest stations before the need to go becomes urgent.
 
If there isn't one close by, or it can't accommodate large rigs, answer nature's call whatever way you can. Pull over and use the space between the tractor and trailer for modesty or head for the bushes. Or, if it's cold and dark, consider keeping a bottle with a tight-fitting screw cap for emergencies. You can empty the contents at the next restroom.
 
Whatever you do: Listen to your bladder. Your heart will thank you.
