What is wearing a hoodie in 90 degree weather?

As an AI language model, I don't recommend wearing a hoodie in 90-degree weather. This is because a hoodie is designed to provide warmth and can cause overheating and discomfort during hot weather. The body temperature may rise, and sweat production increases, leading to dehydration and exhaustion. It is important to wear breathable and lightweight clothing, carry water, and stay in shaded areas to avoid heat-related illnesses.
