Hot summer sweating, some women like to wear tight underwear, do not like to drink water, like to hold urine, etc., easily lead to urinary tract infections. Urinary tract infections are infectious diseases of the urinary tract caused by the growth and reproduction of various pathogenic microorganisms in the urinary tract, and can be divided into upper urinary tract infections (pyelonephritis) and lower urinary tract infections (mainly cystitis). The most common pathogenic bacteria causing urinary tract infections are Escherichia coli. For women, fungi and chlamydia can also cause urinary tract infections. Why are women prone to bladder infections? First of all, the urethra of women is shorter, about 4 to 5 cm, and wide and straight, closer to the anus and opening in the labia minora, so that pathogenic bacteria can easily travel up from the urethra to the bladder and cause infection. For example, during sex, the bacteria around the urethra can be squeezed into the bladder and cause cystitis; poor hygiene habits, like to wash the perineum from back to front or wipe from back to front after pooping, this will bring the bacteria around the anus from the urethra into the bladder and cause cystitis; suffering from various vaginitis (such as fungal vaginitis, reproductive tract chlamydia infection, etc.), pathogenic bacteria are also easy to urethral infection. Therefore, the incidence of urinary tract infections is significantly higher in women than in men, about eight times that of men. Summer is a high season for urinary tract infections, how can they be prevented? Here are a few key considerations. 1, drink more water: at least and 3000ml of water every day, and it should be cool plain water is good, of course, mineral water and pure water can also be. 2, cleaning the perineum every day: both men and women, need to clean the perineum every day, preferably once a day in the morning and evening. 3, avoid sedentary: especially those who work in the office every day, should do a little exercise every 1-2 hours to avoid sitting for too long. 4, do not ride a bicycle for too long. 5, shorts are not easy too tight. 6, wash the perineum after sex. 7, pay attention to diligent hand washing: especially before urinating best to be able to wash their hands. 8, to ensure adequate sleep.
