Individuals in affected areas are advised to stay well hydrated (drink at least 1.5 liters [0.4 gallons] of water per day and avoid alcohol) and to avoid spending time in direct sunlight during the hottest part of the day (generally from 12:00 to 16:00). Be especially on guard against symptoms of dehydration or heat stroke in young children and seniors, as they are particularly vulnerable. Do not hesitate to contact emergency services if necessary.
