Therefore, staying up past 11 p.m. disrupts kidney cell recovery, hormone levels, blood pressure, and the body’s natural rhythm. Prolonged disruption from late nights can begin to indirectly harm the kidneys.
Research shows that people who often stay up after 11 p.m. and sleep less than six hours a night have more kidney problems.
These include protein in the urine, faster kidney disease, and problems with blood pressure and blood sugar—all of which raise the risk of kidney failure.
A study also found that people who sleep less than six hours a night lose kidney function faster than those who sleep seven to eight hours. and eight hours.
