1. Delaying going to a toilet
Keeping your urine in your bladder for too long is a bad idea. A full bladder can cause bladder damage. The urine that stays in the bladder multiplies bacteria quickly. Once the urine refluxes back to the ureter and kidneys, the toxic substances can result in kidney infections, then urinary tract infections, and then nephritis, and even uremia. When nature calls – do it as soon as possible.
2. Eating too much salt
You should eat no more than 5.8 grams of salt daily. Too much of salt does great damage to the kidney.
