Orleans- Orleans has issued a wind chill advisory that is in effect until 11 a.m. on Sunday, with temperatures as low as -15 with wind chill. Even if your local area has not declared a wind chill advisory, it is important to remember the temperatures we are facing can be hazardous to you if exposed for even a few minutes while unprepared.
Exposure to -15 degree wind chill-adjusted temperatures, like those expected over the next week, can have severe effects on the human body. It’s important to note that wind chill makes it feel colder than the actual air temperature, intensifying the impact on the body. Here are some potential effects:
- Frostbite: The most immediate risk is frostbite, which occurs when skin and underlying tissues freeze. Extremities like fingers, toes, ears, and the nose are particularly susceptible. Symptoms include numbness, tingling, and a pale or hardened appearance of the affected area.
- Hypothermia: Prolonged exposure to extreme cold, including wind chill, can lead to hypothermia. This occurs when the body loses heat faster than it can produce it, resulting in a dangerously low body temperature. Symptoms include shivering, confusion, slurred speech, and in severe cases, unconsciousness.
- Hypothermia-Like Conditions: Even without reaching full hypothermia, the body can experience hypothermia-like conditions, leading to increased strain on the cardiovascular system and potential organ damage.
- Increased Heart Rate and Blood Pressure: The body responds to cold by constricting blood vessels, which can raise blood pressure. The heart works harder to pump blood to vital organs to maintain core body temperature.
- Respiratory Issues: Breathing in extremely cold air can irritate the respiratory system, potentially leading to conditions such as bronchospasm. People with pre-existing respiratory conditions may experience worsened symptoms.
- Dehydration: Cold air can be very dry, leading to increased fluid loss through respiration. Combined with the body’s natural response to cold (reduced thirst sensation), this can result in dehydration.
- Reduced Immune Response: Prolonged exposure to extreme cold can weaken the immune system, making individuals more susceptible to infections and illnesses.
It’s crucial to take precautions in such extreme conditions, including dressing in layers, covering exposed skin, and limiting outdoor exposure. Understanding the potential risks and knowing the signs of cold-related illnesses is essential for staying safe in severe winter weather. If you suspect someone is experiencing severe cold-related symptoms, seek medical attention immediately.
