There are health benefits to exercising in higher temps.
In addition to getting more vitamin D, a study conducted by The American Physiological Society found that exercising in warmer environments (slightly above 99 degrees Fahrenheit) raises overall alertness and mental awareness and increases blood plasma volume, which ultimately leads to better cardiovascular fitness. Perhaps most surprisingly, these developments make a person train better in cold temperatures, and additionally far exceed the benefits of conditioning at altitude, according to research conducted at the University of Oregon. Athletes in this latter test performed at 100 degrees Fahrenheit at no altitude and 55 degrees Fahrenheit for ten consecutive days at altitude before their fitness was evaluated. "Be it temperature or altitude, your body will adapt to the stress those variables create in order to perform at its best," explains Matt Berenc, director of education at the Equinox Fitness Training Institute. "Those adaptations will persist for a period even after the stress is removed. So if you have an event coming up like a race, then this could be an additional tool to help give you a competitive edge." Of course, Berenc adds that exercising in heat increases sweat rate and the potential for dehydration, so it should be approached with caution. Here, three summer locales that are both sybaritic and perfect for outdoor activities.
Palm Springs, California
Average summer temperature: 70 to 105 degrees Fahrenheit
While the city is known for its luxe golf courses and tennis courts, it’s worth doing the easy two-mile hiking trail at Tahquitz Canyon. You’ll cross a 60-foot waterfall and find Native American rock art. Afterward, book a Desert Rain Drench at the spa at downtown’s Colony Palms Hotel. The refreshing treatment includes a massage, facial, and moisturizing body wrap.
Scottsdale, Arizona
Average summer temperature: 77 to 103 degrees Fahrenheit
For gorgeous views, hike to the top of Camelback Mountain, a feat that requires strength, discipline, and of course, good heat tolerance. For golfers, take advantage of increased availability at some of the town’s best courses such as Troon North, which passes through Pinnacle Peak’s natural ravines. Then, cool off by kayaking the tranquil Salt River where you might spot wild horses. Regenerate at the Sanctuary on Camelback Mountain, where an Asian-inspired spa menu includes treatments like luk pra kob, a vigorous massage with Thai herbal compresses.
Texas Hill Country
Average summer temperature: 73 to 104 degrees Fahrenheit
This little pocket between Houston, Austin, and San Antonio has winding roads that are quiet and great for cyclists training for long-distance rides. Guests who stay at the secluded Inn at Dos Brisas, a 300-acre resort in Washington, Texas, can also explore the surrounding landscape on horseback (the resort has an expansive equestrian center) or by foot. Afterward, take an organic gardening lesson or borrow one of the resort’s telescopes for some of the best stargazing in the Southwest.
