Physical Activity Concerns

General considerations for physical work and exercising in environmental extremes include:

♦ Plan for decreased physical performance the first two weeks.

♦ Plan your workouts to avoid the hottest or coldest times of the day and allow adequate time for warm-ups.

♦ Drink plenty of fluids and eat enough kcals to replace lost fluids, CHO, and electrolytes.

♦ Be aware of conditions that may predispose you to dehydration (diarrhea, vomiting, fever). Also, avoid substances that can lead to dehydration such as caffeine and alcohol.
