What should you avoid giving to a casualty in moderate hypothermia?

In situations of moderate hypothermia, it is vital to be cautious about what is provided to the casualty. Alcohol is particularly detrimental because it causes blood vessels to dilate, which can lead to a further drop in core body temperature. This reaction can also impair the body's ability to shiver and generate heat, ultimately worsening the hypothermic condition. Providing alcohol not only fails to help rewarm the exposed individual but also increases the risk of complications such as cardiac arrest or further hypothermia.

In contrast, warm tea, hot soup, and fruit juices are safer options that can contribute to rewarming and hydration, as they do not have the same negative effects on circulation and thermoregulation. Therefore, avoiding alcohol is crucial in the management of moderate hypothermia to ensure the best outcome for the casualty.
