Newswise — The summer is a great season for getting in shape, whether by playing a sport, an aerobic exercise routine, or just returning to that familiar running path -- this is the time for activity.

However, exercising during the warmest season of the year can lead to dehydration, profuse sweating, exhaustion, and even to a cardiac event.

Dr. Holly Andersen, director of education and outreach at the Ronald O. Perelman Heart Institute at NewYork-Presbyterian Hospital/Weill Cornell Medical Center, says, "Exercise is the fountain of youth and summer is the perfect time to get re-connected with your body."

She offers the following tips to those looking to resume or begin a workout routine this summer:

* Talk to your doctor. You should always consult your physician before beginning or changing your exercise regimen in any way.

* Take your workout indoors. When it is too hot or humid outside you should exercise in a cool, air-conditioned space. Extreme temperatures can interfere with circulation, making breathing more difficult and causing chest pain.

* Drink plenty of fluids. Throughout your workout routine it is important to drink plenty of water, even before you feel thirsty. If you are prone to lightheadedness (from low blood pressure), are an endurance athlete, or over age 75, you should replenish your "electrolytes" as well -- having a little salt can be important for you.

* Try to maintain an even body temperature. After your workout you should not take an extremely hot or cold shower, or a sauna bath, as these can increase the workload on your heart.

* Be an early bird. If you truly enjoy exercising outdoors, take advantage of the coolest times of day -- the early morning and evening hours.

* Wear sunscreen. If you have a sunburn, it will decrease your body’s ability to cool itself off. Always remember to apply sunscreen to your entire body every morning.

* Take it slow. Start your exercise regimen slowly and pace yourself throughout the workout, including plenty of time for breaks and to drink fluids.

* Have fun. Taking time to exercise is taking time for you. Enjoy it -- smile, breathe deeply and clear your mind. Exercising to music is mood and energy enhancing, but if you are outside wearing headphones, PAY ATTENTION!
