Whether you're planning a vacation to get a break from the winter blues or taking advantage of some local beaches during the summer -- failing to follow basic beach safety rules can throw sand on your plans.

Too much exposure to the sun can cause heat exhaustion or short- and long-term damage to your skin. Meanwhile, hidden dangers may lurk within those placid waters lapping at the shore.

Taking the following steps can keep you sand-and-surf safe so you can make the most of your beach days.

Heat dangers

It is easy to become overheated while lounging on the beach. As the sun's rays beat down, the body's cooling system can become overwhelmed. Heat exhaustion occurs as body temperature rises, preventing perspiration and leading to thirst, fatigue, and leg and abdominal cramps. Left untreated, heat exhaustion can develop into heat stroke, a potentially life-threatening condition.

While heat illness can strike anybody, certain populations are especially vulnerable. This includes:

• Children
• Seniors
• People who are obese
• Patients with certain medical conditions (e.g., diabetes or heart disease)

Avoid heat illness by taking these steps to stay cool. Sit under an umbrella, or other shade, wear a wide-brimmed hat and drink plenty of water or other fluids to keep from overheating. Remember to avoid alcohol and drinks that contain caffeine, which can cause dehydration.
