Weather Can Have a Chilling Effect on Workouts, Say Experts
June 30, 2005 -- The weather in your area may be a plus or a minus when it comes to exercise.
Sure, you can exercise year-round inside. And many people brave hot, cold, rainy, or snowy conditions to be active. But the weather can still make a difference, new research shows.
The CDC advises getting at least half an hour of moderate intensity physical activity five or more days per week. According to the CDC, moderate-intensity physical activity includes walking at a brisk pace, biking on a level terrain, using a stationary bicycle, aerobic dancing, or water aerobics.
Ray Merrill, PhD, MPH, and colleagues aren't offering new excuses to slack on fitness. Instead, they looked at the weather's effects on workout habits.
Merrill is an associate health sciences professor at Brigham Young University. His report appears in the American Journal of Health Behavior.
Prime Exercise Conditions
Looking for the best weather for exercise? Head to "big sky" country.
Here are the five top-ranked areas, with the percentage of people meeting moderate physical activity guidelines:
- Montana: 60.9%
- Utah: 59.2%
- Wisconsin: 57.9%
- New Hampshire: 55.9%
- Vermont: 55.6%
The five with the lowest percentages were:
- Puerto Rico: 30.9%
- Hawaii: 36.4%
- North Carolina: 37.4%
- Kentucky: 37.6%
- Mississippi: 38.4%
For the complete list,
Montanans are most likely to meet physical activity recommendations, says Merrill. People living in Puerto Rico are the least likely to do so, he writes.
You don't need radar to tell the difference between those climates.
The highest-ranked regions for physical activity also had the most dry, moderate days. Those at the bottom 25% of the list had the highest percentage of sticky, steamy, tropical days.
The time of year also affected activity. Activity peaked with:
- Moist, moderate winters
- Dry "polar" springs
- Dry, tropical summers
- Dry "polar" falls
Why the Difference?
The researchers suggest three reasons for the patterns:
- Some active people may consider climate in choosing where to live.
- Some older people may not feel comfortable in gyms. They may wait for good weather to be active.
- Good weather is often considered safer and more pleasant.
- Walking and cycling, two popular activities, are more convenient in good weather.
