April 25, 2013— -- intro: Ever wonder why you feel so great after you break a sweat? Turns out, exercise isn't just an effective flab-fighter—it's a remedy for pretty much any troubling health issue you are facing: anxiety, insomnia, back pain—even hot flashes.

"When it comes to preventing health problems, exercise is one of the best medicines we have," says David Katz, MD, founding director of the Yale University Prevention Research Center. But some workouts are better than others for healing what ails you. Try these active solutions.

Getting your heart pumping increases the release of mood-stabilizing neurotransmitters, like serotonin, norepinephrine and GABA, which is why you can feel like you're sweating off stress during Spinning class.

The good vibes continue: A study in the journal Medicine & Science in Sports & Exercise showed that doing 30 minutes of moderate-intensity exercise (jogging, not sprinting) makes you more resilient against stressors hours later, like preparing for that big meeting with your boss. And over the long term, "people who work out consistently report less overall stress, anxiety and depression," Otto says.

Your fitness Rx: Do a quick blast of cardio on the morning of a hectic day, or to unwind at the end of one. If possible, take it outside—numerous studies show that fresh air provides a big mood boost.

Folks who meet the recommended physical activity guidelines of 150 minutes a week are 65 percent less likely to feel tuckered out during the day, a 2011 study found.

"Exercisers fall asleep faster, suffer fewer middle-of-the-night wake-ups and have a reduced risk of sleep disorders," says study co-author Brad Cardinal, PhD, co-director of the sport and exercise psychology program at Oregon State University.

Translation? You'll snooze more soundly and feel more energized on the go.

"We aren't sure why activity primes your body for sleep so well, but it's likely a combination of factors, including lowering your core body temperature, increasing the sleep-promoting hormone melatonin and supporting a biological need to restore energy levels and repair cells and tissues when you sleep," Cardinal says.

Your fitness Rx: Aim for 150 minutes per week of moderate activity. Try to work in some yoga; a 2012 study found that practicing yoga along with deep-breathing techniques relieved insomnia within four months. Wrap up your workout at least three hours before you hit the sack: Exercise can be too stimulating near bedtime.
