Cold-related diseases are health conditions that arise due to exposure to low temperatures. Common examples include hypothermia, where the body loses heat faster than it can produce it, and frostbite, which occurs when skin and underlying tissues freeze. These conditions can lead to serious complications if not treated promptly. Additionally, prolonged exposure to cold can weaken the immune system, making individuals more susceptible to illnesses like the common cold or influenza. It is essential to dress appropriately and limit time spent in extreme cold to prevent these health issues.
