Why is summer so problematic? Dr. Jang-hee Lee, a urologist at Incheon Himchan General Hospital, points to a combination of factors: “Hot weather causes dehydration, while prolonged exposure to cold environments or frequent intake of chilled foods can constrict pelvic blood vessels, impairing prostate circulation and function.” These conditions can aggravate urinary symptoms and prostate inflammation.
Three Summer Risks to Prostate Health: Dehydration, Infection, and Cold Exposure
Several factors make summer a perilous season for prostate health. First, dehydration. High temperatures drive excessive sweating, lowering bodily fluids and concentrating urine. This concentrated urine irritates the urinary tract, potentially causing inflammation in both the bladder and prostate. Elevated levels of calcium, uric acid, and salts in urine also increase the risk of urinary tract or prostate stones.
Second, bacterial infections thrive in summer’s heat and humidity, which create a moist environment around the genitals, encouraging bacterial growth. Bacteria from the urethra or anus can migrate to the prostate, triggering inflammation. For those with prior prostatitis, summer’s toll on immunity heightens the chance of symptom recurrence or worsening.

Practical Steps to Safeguard Prostate Health in Summer
To protect prostate health during warmer months, consider these recommendations:
- Hydrate Wisely
Drink 1.5 to 2 liters of water daily, but reduce intake two hours before bedtime to minimize nighttime urination (nocturia). Avoid diuretic drinks such as coffee, alcohol, and caffeinated or sugary carbonated beverages.
- Limit Cold Air Exposure
Maintain indoor-outdoor temperature differences within 5–6°C and protect the lower body from direct air conditioning. Extended cold exposure to the pelvic area can reduce blood flow, triggering inflammation.
- Stay Active
Prolonged sitting compresses the pelvis and prostate. Stand, stretch, or walk briefly every hour to boost pelvic blood circulation.
- Use Warm Sitz Baths and Maintain Underwear Hygiene
A warm sitz bath for 10–15 minutes improves pelvic blood flow and relieves discomfort. Wear breathable cotton underwear and change frequently to curb bacterial growth.
- Seek Early Medical Care
Burning during urination, a persistent feeling of incomplete emptying, frequent nighttime urination, reduced libido, or ongoing fatigue may signal prostate problems. Consult a urologist promptly to pinpoint the cause and prevent complications.
Dr. Lee stresses the need for vigilance: “Prostate symptoms in summer can easily recur or become chronic. Healthy habits and timely medical intervention are the best defenses against long-term problems.”
By recognizing summer’s unique risks and adopting proactive strategies, men can maintain prostate health throughout the year.
