The clothing is your first line of defense against change. In the cold, many layers of clothing trap air inside, so heat more than just one thick garment. Keep the center of your body warm. To wear a hat is important. And a gold standard against the cold. To consider how to protect yourself before you start feeling cold. Avoid sweating and keep your clothes dry. Wet clothing can lose up to 90% of the insulating properties.
In a hot climate, clothes and hat can be the main safeguard you from the sun. Keep your skin covered to prevent sunburn. A makeshift hat or head scarf, can provide shade and keep the body cool, if you sweat. (Think of it as a last resort there is urine or any other liquid you can find) .- Remember that survival is rarely attractive .-
