SATURDAY, Aug. 2 (HealthDayNews) -- When you're hitting the links this summer, make sure you don't get teed off by heat-related illnesses.

Those wide open golf fairways are fully exposed to the sun and can be dangerous places if you don't take the proper precautions.

Heat-related illnesses occur when your body temperature control systems overload and your body can no longer cool itself, says the U.S. Centers for Disease Control and Prevention (CDC).

The two most serious forms of heat illnesses are heat exhaustion and heat stroke. Heat exhaustion warning signs include: heavy sweating, paleness, muscle cramps, tiredness or weakness, headache or dizziness, nausea or vomiting, and faintness.

If left untreated, heat exhaustion can lead to heat stroke. As many as 40 percent of people who get heat stroke may die as a result of brain damage. Heat stroke warning signs include: body temperature of 103 degrees F or higher; red, hot, dry skin; throbbing headache or dizziness; nausea; confusion or unconsciousness.

It's easy to prevent your golf game from turning into a life-threatening heat-related emergency. Here's are some prevention tips from the CDC:

• Avoid dehydration by drinking plenty of water, sports drink or other suitable beverage. Do not drink liquids that contain alcohol, caffeine or large amounts of sugar. These will actually cause you to lose more body fluid.
• Try to play golf at cooler times of the day, such as morning or evening.
• Rest as often as you can in shady areas. Many golf courses have trees lining the fairways. Take advantage of them.
• Wear a wide-brimmed hat and lightweight, light-colored, loose-fitting clothing.
