What causes urine to be below 90 degrees?

Urine temperature below 90 degrees Fahrenheit can occur due to several factors, including environmental conditions, such as exposure to cold air or surfaces, and the time elapsed since urine was produced. Additionally, if urine is stored in a container for an extended period before testing, it can cool down significantly. In some cases, certain medical conditions or medications may also affect body temperature regulation, potentially leading to cooler urine.
