Why is winter more likely to cause urinary tract infections?

THIỆN NHÂN (THEO onlymyhealth) |

Winter is prone to urinary tract infections due to cold weather reducing blood circulation, weakened immunity and the habit of drinking less water.

Why does cold weather increase the risk of urinary tract infections?

According to Dr. P Vamshi Krishna, Senior Consultant and Head of the Department of Urology, CARE Hospital, Banjara Hills, Hyderabad (India), cold weather can affect urinary tract health through mechanisms such as immunodeficiency, reduced blood circulation, changes in lifestyle habits and creating a favorable environment for bacteria to grow.

During winter, several factors can increase your risk of urinary tract infections (UTIs):

Reduced blood circulation: Cold weather constricts blood vessels, reducing blood flow to the kidneys and bladder, reducing the ability to eliminate bacteria.

Reduced fluid intake: Drinking less water and going to the bathroom less often can create conditions for bacteria to grow in the urinary tract.

Weakened immune system: Prolonged cold weakens the immune system, making the body susceptible to infection.

Warm, tight clothing: Wearing tight, warm clothing can create a moist environment, ideal for bacteria to grow.

Vitamin D deficiency: Reduced sunlight exposure in winter can weaken the immune system and increase the risk of UTIs.

Taking vitamin D supplements and taking precautions will help reduce the risk of infection during cold weather.

The link between vitamin D deficiency and urinary tract infections

Vitamin D deficiency is strongly linked to urinary tract infections due to its role in maintaining the immune system and protecting the body from bacteria, says Dr. Krishna. Vitamin D helps stimulate the production of antimicrobial peptides in the urinary tract, which help prevent bacteria from entering and growing. When the body is deficient in vitamin D, its natural defenses are reduced, increasing the risk of UTIs, especially recurrent infections. Studies show that people with UTIs often have lower vitamin D levels than healthy people.

Common habits that contribute to your risk of UTIs

Dr. Krishna says many factors besides seasonal changes can increase the risk of urinary tract infections. Women are at higher risk due to their shorter urethra. Factors such as sexual activity, hormonal changes, chronic diseases (diabetes, kidney stones), poor hygiene habits, and winter (less bathing, wearing damp clothes, less exercise) all create conditions for bacteria to grow and weaken the immune system, thereby increasing the risk of UTI.

How to Prevent UTI in Winter

To prevent urinary tract infections (UTIs) in winter, you can:

- Drink plenty of water to flush out bacteria.

- Wipe from front to back and avoid harsh soaps.

- Do not hold urine to prevent bacteria from accumulating.

- Wear warm clothes and avoid cold pelvic area.

- Choose cotton underwear, avoid tight pants.

- Pee after sex.

- Eat foods rich in vitamin C and probiotics.

- Limit sugar to reduce bacterial growth.

- Exercise regularly to boost immunity.
