CHARLESTON, W.Va. -- Dear Cindy,
I don't know if it is my age or simply the heat, but I can't seem to exercise like I once was able to. I'm a walker and a tennis player and love to be outside, but I've had to stop the past two times out because I was feeling exhausted. -- Renee
Dear Renee,
It's official. Summertime is here and it's hotter than the Fourth of July. We're eager to burst through the walls that surround our workouts and get reacquainted with fresh air and natural settings. The sunshine puts smiles on our faces and sweat on our brow as we take our favorite activities outside. However, this time of year can actually drive people inside where the atmosphere is a more predictable.
But don't throw in the towel just yet. Instead, carry it with you and give yourself time to adapt. You can prepare to handle the heat and humidity that accompanies this beautiful season. Sure, we can't control nature's thermostat, but we can make sure our own is in good working order.
As we age, it takes a little longer for our body to adapt to hot temperatures. Gradually introducing muggy workout conditions requires time, patience and a healthy respect for the sun -- particularly how dramatically it can impact your activity and your health.
Many factors affect your ability to work and to play outside: age, temperature, humidity, exercise intensity, hydration, diet and time of day. Simply sitting in the heat can be a challenge for some. For instance, a 90-degree day with 80 percent humidity feels like 113 degrees. Obviously, this is not an ideal environment to play tennis if you normally play on an air-conditioned court. The same is true for walking. The process of heat acclimation -- getting accustomed to the outside temperatures -- is a must to exercise safely and to prevent heat illness.
Exercise caution

The same is true for walking. The process of heat acclimation -- getting accustomed to the outside temperatures -- is a must to exercise safely and to prevent heat illness.
Exercise caution
We need at least seven to 10 days of repeated exposure to heat to safely acclimate to the change of environment. The amount of stress on the body is directly related to a combination of air temperature, humidity level, hydration level and length and intensity of the workout. Any one factor or a combination of them can be dangerous -- even fatal -- if symptoms are ignored.
Initially, cut the duration of your activity in half. Go easy on the intensity. Your heart is working twice as hard trying to keep up with the exercise demands while cooling you at the same time.
If possible, exercise early in the morning or late in the evening when the heat and humidity are lower. If you have no control over the time of day, the duration or the intensity -- for example, a competitive tennis match -- use caution from noon to 5 p.m. by taking the allotted breaks, hydrating frequently and using cool, wet towels around your neck whenever possible.
It is essential to drink plenty of water before your activity. It is just as important to continue drinking 6 to 8 ounces of water or sports drink every 15 to 20 minutes until you have completed your activity. This will make a tremendous difference in your system's ability to deal with the heat and stress.
Don't ignore symptoms
Heat-illness symptoms indicate stress and a need to stop exercise. These symptoms are: dizziness, headache, chills, fatigue, tachycardia (rapid heart rate), diarrhea, nausea, leg cramps or any general feeling that something isn't "right." If any one of these is present, stop the workout, remove yourself from the heat and drink water.
How hot is too hot?
Because it can be different for everyone, pay attention and base your decisions on your feelings and the presence of heat stress symptoms. Never rely on someone else's perception as to whether it's too hot to continue. You need to know when to throw in the towel. However, by preparing for the heat and by listening to your body, you can safely move your activities to the beautiful outdoors.
