Getting all hot and bothered isn’t necessarily good for your heart.

During times of extreme heat, those with heart disease or who take diuretics and high blood pressure medicine are more susceptible to heat exhaustion and heat stroke.

Heat exhaustion occurs when a person is overexposed to heat, resulting in loss of body fluids and salt. Symptoms include weakness, heavy sweating, nausea, giddiness, dizziness, collapse, fatigue, and cool, clammy, red or flushed skin. Those suffering from heat exhaustion should immediately go inside. Rest, cool liquids to drink and cool baths are recommended.

If left untreated, heat exhaustion can become heat stroke, a life-threatening condition in which the body becomes dangerously overheated. Symptoms include: faintness, headache, loss of consciousness, body temperature at or above 104 degrees Fahrenheit, rapid pulse and symptoms of heat exhaustion. Victims of heat stroke should seek immediate medical attention.

Those at risk of heat exhaustion and heat stroke need to protect themselves. Some tips include:

• Stay out of direct sunlight.
• Stay in air-conditioned areas.
• Take cool baths or showers.
• Place ice bags or wet towels on your body, and sit or lie near a fan.
• Avoid strenuous activity.
• Wear lightweight, light-colored, loose-fitting clothing made of natural fibers.
• Drink plenty of fluids, such as water, vegetable juices and iced tea.
• Avoid alcoholic beverages or drinks with a high salt content.
