We’ve all heard it before – encouragement to exercise to trim our waistline or to speed up our metabolism. However, there may be more benefit to lacing up those sneakers than you’d think. Recent studies have established a link between exercise and cognition, making physical activity even more important.
Exercise has been shown to improve sleep and mood, decrease stress, and even increase libido. It also can bolster our self-esteem and ability to problem-solve and to remember details. In fact, strength training has even been shown to reverse cognitive decline to a degree in aging adults with mild impairment. Though the medical community is still trying to elucidate exactly how exercise boosts our brains physiologically, increased circulation to the brain and modulation of the hypothalamus-pituitary-adrenal axis that regulates the body’s response to stress have been implicated as the bearers of benefit. While exercise can be advantageous for everyone, it perhaps is even more valuable to those struggling with mood disorders. Exercise can help combat anxiety and depression and quell the symptoms of Attention Deficit Hyperactivity Disorder and Post Traumatic Stress Disorder as it helps the brain to pump out neurotransmitters and pain-fighting endorphins. Exercise makes addiction management easier, as well, and has recently been shown to help alcoholics lessen consumption.
So, how much exercise exactly is enough to illicit tangible cognitive benefit, you ask? Any amount of weight lifting, running, walking, or yoga helps, but habitual activity helps the most. Studies cite that a few consecutive weeks of participation in a fitness regimen yielded notable, positive results in subjects. Try to make exercise part of your daily routine to encourage good fitness habits. If you find the idea of adopting a strenuous new fitness program intimidating or off-putting, have no fear. Moderate exercise is enough to do the trick. The Mayo Clinic cites both brisk walking and mowing the lawn as examples of moderate activity, so an average fitness level is adequate for yielding positive mental results.
If you’re thinking about beginning an exercise program for the first time, start gradually. Begin with walking for 10 to 15 minutes twice daily, and add 1 or 2 minutes to your session every time you walk until you can walk continuously for 45 to 60 minutes. The same principle can be used when beginning other fitness routines involving biking, swimming, running, etc. Begin a weight training program to strengthen bones and tendons using 3 to 5 pound dumbbells, and increase the weight you use by a pound once you can easily perform 30 consecutive repetitions. Be careful to pay close attention to posture and form. Contact your physical therapist or a personal trainer for assistance with designing an appropriate exercise program. Don’t hesitate to contact your physician, either, if you have questions about whether a particular exercise program is safe and suitable for your age group or current fitness level. Consider these tips to make the most of your workout:

According to the National Institutes of Health, an estimated 19.1% of U.S. adults 18 and older had an anxiety disorder in the past year. Anxiety disorders were higher for females (23.4%) than for males (14.3%). An estimated 31.1% of U.S. adults experience an anxiety disorder at some time in their lives.
There are a wide variety of anxiety disorders and will vary by the objects or situations that induce them. However, the features of excessive anxiety and related behavioral disturbances are similar. Anxiety disorders can interfere with daily activities such as job performance, school work, and relationships. Symptoms include: distress, nausea, shortness of breath, bowel pattern changes, excessive perspiration, frequent laughing or crying, restlessness, and is often associated with depression. While there are many types and degrees of anxiety and there is no substitute for medical and psychological care, there are some simple and basic tools to help manage the problem…daily exercise is one easy, affordable and accessible suggestion for most. Multiple studies have discussed the incidence of unhealthy self management of anxiety, including the use of alcohol and recreational drugs.
Last week, I presented coping tips for the management of anxiety. In this column, I will discuss one of the most understated benefits of exercise – mental health! Specifically, aerobic exercise (exercise that increases your heart rate for 30 minutes or more) such as walking, biking, running, swimming, hiking, elliptical & stepper machines to name a few, is the secret to “runner’s high.” This exercise euphoria is not limited to runners alone, but all who engage in aerobic exercise are more likely to experience high energy, positive attitude and mental wellness.
Physical activity, specifically aerobic exercise, is a scientifically proven useful tool for preventing and easing anxiety and depression symptoms. Studies in the British Journal of Medicine and the Journal of Exercise and Sports Science found that anxiety and depression scores were significantly reduced in groups that engaged in aerobic running, jogging or walking programs, 30-45 minutes 3-5 days per week for 10-12 weeks, when compared to a control group and a psychotherapy counseling group.
According to research reported in sports medicine journals, exercise reduces anxiety and depression in two ways, psychologically (mentally) and physiological (physically).
