Brazilian experts advise winter precautions for muscles, skin and kidneys

Health professionals in Brazil highlight several risks that the cold season can bring and offer practical measures to mitigate them. Physiotherapist Thais Tarabal explains that low temperatures cause natural muscle and blood‑vessel contraction, reducing circulation and increasing joint stiffness. She recommends protecting the body with proper clothing, maintaining regular physical activity, doing daily stretches and staying hydrated to preserve mobility and lessen pain.

Geriatrician Bruno Vial notes that aging reduces muscle mass, body fat and peripheral circulation, making older adults feel colder and more vulnerable to respiratory infections, cardiovascular issues and kidney problems. He advises caregivers to keep indoor environments warm, dress elders in layers, encourage fluid intake and avoid sudden temperature shifts.

Dermatologist Gabriela Grossi warns that winter’s low humidity, wind and heated indoor spaces can dehydrate skin and lips, especially in seniors and people with diabetes. She recommends regular use of moisturisers, avoiding overly hot showers and keeping environments ventilated.

The Rio de Janeiro State Health Secretariat adds that reduced thirst in winter leads many, particularly the elderly, to drink insufficient water, raising the risk of urinary‑tract infections and kidney stones. They suggest consuming two to three litres of water daily, staying active and limiting salty or ultra‑processed foods.

Otolaryngologist Alexandre Kumagai clarifies that cold water itself does not damage the throat or voice; discomfort stems mainly from dry air, dehydration and vocal overuse. Proper hydration and avoiding extreme temperature changes are the key preventive steps.
