The heat index is going to be dangerously high this week and it won’t cool down much at night. Warm nighttime temperatures can increase your risk of heat illness because your body can’t recover from the day’s heat. If you don’t have air conditioning, use ice packs or frozen water bottles to help you cool off overnight and drink plenty of water throughout the day, even before you start to feel thirsty.

El índice de calor será peligrosamente alto esta semana y no refrescará mucho por la noche. Las altas temperaturas durante la noche pueden aumentar el riesgo de enfermedades relacionadas con el calor, ya que el cuerpo no puede recuperarse del calor del día. Si no tienes aire acondicionado, utiliza bolsas de hielo o botellas de agua congelada para refrescarte durante la noche y bebe mucha agua a lo largo del día, incluso antes de empezar a tener sed.
