How can you help someone suffering from hypothermia?

Moving someone suffering from hypothermia to a warmer place and removing their wet clothing is the most effective way to help them. Hypothermia occurs when the body loses heat faster than it can produce it, leading to a dangerously low body temperature. Wet clothing can exacerbate this condition because it conducts heat away from the body more rapidly than dry clothing. By relocating the person to a warmer environment and allowing them to get into dry clothes, you can significantly increase their chances of warming up effectively.

In addition to moving to a warmer location and removing wet clothing, providing gentle warmth through body heat or blankets can also aid recovery. However, it's crucial to ensure that any warming is done gradually to avoid shock to the system.

The other options, such as giving cold water to drink or leaving the person outside, would worsen their condition. Wrapping someone tightly in a blanket can potentially restrict circulation and is less effective than using multiple layers or ensuring warmth through a proper means of insulation while still allowing for circulation.
