BETTER HEART HEALTH
Cycling is a cardiovascular activity, so it goes without saying it makes your heart stronger and healthier. Exercise like cycling also makes your skeletal muscle more insulin-sensitive, so you’re better able to control your blood sugar level—something scientists now know is essential for clear arteries and good heart health. The overall protective impact cycling has on your heart is pretty impressive. The British Medical Association reports that cycling just 20 miles a week slashes your risk of coronary heart disease in half when compared with staying sedentary. That’s just three miles a day, or five miles four times a week.
A BIGGER, HEALTHIER BRAIN
Neuroscientists think of exercise as Miracle-Gro for the brain because it’s a powerful, neuron-building stimulant that works remarkably fast. Exercise that raises your heart rate, like cycling, dramatically increases the production of nitric oxide (a potent vasodilator) and neurotrophins (growth factors) such as brain-derived neurotrophic factor and a protein aptly named noggin, which promotes stem cell division and new brain cell formation. The end result is that cycling will give you better, sharper memory skills, stronger concentration ability, more fluid thinking and reasoning, and greater problem-solving abilities. All this brain-health building also protects you from age-related cognitive decline and Alzheimer’s disease and other dementias.
SLEEP LIKE A BABY
It’s hard to overstate the importance of sleep. Your body and brain heal while you rest. Without enough sleep, your hormone levels (especially stress hormones) get out of whack, and you’re more likely to overeat and gain weight, as well as have more mood disorders and lowered immunity. In one of the most striking studies on the subject, the sleep habits and body-weight trends of 68,000 women were studied over a period of 16 years. The researchers found that those who slept only 5 hours a night were 32 percent more likely to gain 33 pounds or more over the course of the study compared with their peers who slept 7 hours a night.MILES OF SMILES
You rarely see someone finish a ride grumpy. To the contrary—they’re usually grinning from ear to ear. Cycling lifts your spirits—nearly immediately. In one study from Bowling Green State University, researchers found that as little as 10 minutes of cycling improved the mood in a group of volunteers compared with their peers who just relaxed for the same amount of time.
