Smoking is not only bad for your lungs, it is also severely bad for your kidneys as well. No, in fact, it is bad for almost every organ in our body, as stated by the Centers for Disease Control and Prevention.
The relation of smoking and kidney disease has been shown by many studies. As the American Association of Kidney Patients (AAKP) explains, smoking is the number one cause for ESRD (end stage renal disease).
Smoking increases the heart rate and blood pressure, as well as decreases the blood flow and narrows the blood vessels in kidneys. This unhealthy habit can aggravate existing kidney disease, and can speed up the loss of kidney functions. The best way to prevent this is to stop smoking, as this habit is harmful for every part of your body.
RECOMMENDATION: Try your best to quite smoking. I know it’s not easy, but you will benefit a lot from not smoking.
8. Drinking too much coffee (or caffeine, in general).
If you consume too much caffeine, your blood pressure will be increased, which will burden the function of kidneys. Over longer periods, this can cause kidney damage. Kidney International has published a 2002 study according to which the consumption of caffeine is strongly related to kidney stones. Caffeine can raise the excretion of calcium in urine.
Nevertheless, most people won’t have any problem if they consume caffeine in moderate amounts. So consuming 3 cups of tea, 1 to 2 cups of coffee a day is perfectly fine. But you shouldn’t forget the other sources of caffeine like energy drinks, cocoa, soft drinks, chocolate, and some medications, so make sure you limit their amount too.
