The difficulty to walk can vary depending on various factors such as personal tolerance, clothing, wind chill, and overall health. However, extremely cold temperatures can make it challenging to walk comfortably or safely for most individuals.
In general, when the temperature drops below -20 degrees Celsius (-4 degrees Fahrenheit), it becomes increasingly difficult to walk due to the extreme cold. At such low temperatures, exposed skin can freeze within minutes, and the risk of frostbite and hypothermia significantly increases. Additionally, icy conditions and reduced traction can make walking more hazardous.
It's important to note that the specific temperature at which it becomes difficult to walk can vary among individuals. Factors such as age, physical condition, clothing insulation, and acclimatization to cold weather can affect an individual's tolerance. It is always recommended to dress warmly in multiple layers, cover exposed skin, and prioritize safety when venturing out in extremely cold temperatures.
