Winter has officially started and it is imperative to stay warm now.
Doctors have shared health risks caused by lower temperatures and the protective measures the public could take.
Lu Chin-heng, director of Peace of Mind’s Urology Clinic, wrote on Facebook that urinary problems, such as frequent urination, nocturia (waking up at night to urinate), or urinary retention due to benign prostatic hyperplasia (BPH), increase during cold days.
Cold temperatures cause “cold-induced diuresis,” which increases the frequency of urination, he said.
Lu advised people not to reduce their water intake, and instead avoid excessively caffeinated drinks in the evening, and keep their abdomen and lower body warm, adding that people with BPH or existing urinary tract problems should seek medical attention.
When cold receptors are activated, the muscles around the bladder contract, he explained, suggesting people wear thermal pants or waist warmers, avoid sitting on cold chairs for long periods of time and urinate more often.
There is also an increased risk of urinary tract infections because people tend to hold their urine or drink less water on cold days, which can lead to an infection, Lu said.
“Do not retain urine, maintain consistent water intake and consult a doctor immediately if you experience pain or burning during urination,” he advised.
Lu further said, “Low temperatures also reduce the flow of synovial fluid, reducing joint mobility, which could lead to joint stiffness and increased pain.”
He suggested that people warm up their bodies before exercising after waking up, keep their joints warm and avoid sudden or strenuous exercise.
Furthermore, Lu revealed the reason why they feel depressed during winter, saying, “People may also experience seasonal depression because less sunlight would affect the secretion of serotonin and melatonin. So they should get more sunlight during the day, maintain social interactions and regular activities, and seek professional help if the feeling lasts for more than two weeks.”
“Staying warm, drinking enough water, not urinating and moving slowly are important health guidelines for cold days,” the health expert suggested to keep health risks caused by winter at bay.
