<p style=";text-align:left;direction:ltr">Arabia Weather - In the winter, many people find themselves suffering from a common problem, which is a runny nose in cold weather. Have you ever wondered? Why does this happen? Why is the breathing experience different in cold than in warm weather? In this article, we will explore the body&#39;s mechanisms and responses when dealing with cold, and how the nose in particular reacts to cold air.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"></p><h2 style=";text-align:left;direction:ltr"> Why do our noses run in cold weather?</h2><p style=";text-align:left;direction:ltr"> A runny nose is a common phenomenon that occurs in a large percentage of people, ranging between <strong>50 and 90 percent</strong> , when they are exposed to cold weather. This condition is known as <strong>“cold-induced rhinitis,”</strong> and it appears more frequently in individuals who suffer from conditions such as asthma and eczema.</p><p style=";text-align:left;direction:ltr"> The nose plays a vital role in warming and humidifying the air that a person breathes, to avoid irritation of the cells in the lung. When cold air passes through the nose, it reaches a temperature of about <strong>26-30 degrees Celsius</strong> , with a humidity of up to 100 percent. This process shows that the nose It plays an effective role in converting air into a warm and moist state before it reaches the lungs.</p><p style=";text-align:left;direction:ltr"> The nerves in the nose respond to dry, cold air by sending signals to the brain, which increases blood flow to the nose, causing the blood vessels to heat the air. This response also increases the production of mucus to moisten the air, and activates the cells of the immune system to increase humidity.</p><p style=";text-align:left;direction:ltr"> Although this process is necessary to maintain respiratory comfort, it is accompanied by the loss of large amounts of fluid, and nasal fluid loss can range between <strong>300 and 400 milliliters</strong> , which highlights the importance of the balance of heat and humidity to maintain nasal comfort under cold conditions.</p><p style=";text-align:left;direction:ltr"> In this process, it shows how the body reacts intelligently to adapt to cold challenges, and how it efficiently tries to balance the amount of heat and moisture lost from the nose. This amazing reaction of the body reflects advanced biological technology in adapting to the changing environmental conditions of the human body. </p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"><img alt="" src="/sites/default/files/uploads-2020/%D9%84%D9%85%D8%A7%D8%B0%D8%A7%20%D8%AA%D8%B3%D9%8A%D9%84%20%D8%A3%D9%86%D9%88%D9%81%D9%86%D8%A7%20%D9%81%D9%8A%20%D8%A7%D9%84%D8%B7%D9%82%D8%B3%20%D8%A7%D9%84%D8%A8%D8%A7%D8%B1%D8%AF%D8%9F.jpg" style="width: 400px; height: 600px;" /></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> Read also:</p><p style=";text-align:left;direction:ltr"> <a href="https://www.arabiaweather.com/ar/content/%D9%85%D8%A7%D9%87%D9%8A-%D9%85... is Raynaud&#39;s syndrome?
