What is an appropriate precaution and/or modification for exercising in higher ambient temperatures?

Salt tablets are not recommended because they can irritate the gastrointestinal tract and worsen dehydration if fluid intake is insufficient; electrolyte needs are better met through food and sports beverages.

Eight ounces of water once per hour is far below adequate hydration for exercise in heat; ACSM recommends drinking regularly before, during, and after exercise based on sweat rate, typically every 15-20 minutes.

Loose-fitting, lightweight, and light-colored clothing minimizes heat absorption from the environment and allows air circulation around the body, enhancing convective and evaporative cooling. This supports the body's primary heat-dissipation mechanisms during exercise in hot conditions. It is a widely recommended behavioral modification by ACSM and public health guidelines for exercising in the heat.

Clothing designed to trap body heat would impair evaporative and convective cooling, dramatically increasing core temperature and the risk of heat exhaustion or heat stroke.
