chronic insomnia sufferers. A study performed by Dr. Kathryn J. Reid and others found that aerobic exercise had strong positive results on a group of participants who’d previously regularly encountered sleep problems. “Results from this study indicate that a sixteen-week program of moderate intensity aerobic physical activity plus sleep hygiene education is effective in improving self-reported sleep quality, mood, and quality of life in older adults with chronic insomnia,” the authors wrote. “These results highlight the potential of structured physical activity programs to improve the effectiveness of standard behavioral approaches for the treatment of insomnia, particularly in a sedentary older adult population.”15
A group at Northwestern University’s Feinberg School of Medicine built upon this study by drilling down on the data gleaned and then studying the interconnection between exercise and sleep. What they found is important to consider: exercise is not a magic pill. If you’re having trouble sleeping, you can’t solve the problem with one session at the gym. They found that, even after two months, the effects of exercise on sleep were minimal. But by the end of the 16-week study, the results were considerable, with participants getting as much as an hour-and-a-quarter extra sleep per night.16
So, there’s a clear connection between exercise and sleep, but you’re going to need to give it time. But, given the overall benefits of exercise on your health, committing to an exercise routine is always a good idea, even if you won’t feel the benefits on your sleep right away.
There are varying ideas about how much exercise is necessary to affect sleep, but a commonly stated amount is 2.5 hours a week of aerobic exercise, coupled with some resistance work. “Brisk walking, light biking, elliptical machine, anything that increases your heart rate so that you can still talk while exercising but have to catch your breath every few sentences or so, is considered moderate exercise,” recommends Dr. Christopher E. Kline of the University of Pittsburgh.17
Giving Your Mind a Break
One of the many reasons why people have trouble sleeping, is not being able to get your mind to turn off. We’ve all been there: You have a huge meeting coming up, or something disruptive (either positive or negative) happened during the day, or you got a phone call just before bedtime that got you riled up. Your head hits the pillow, but you might as well be running laps around your house because your mind is busy with this inciting event. You wind up lying there for hours, and sleep seems as unapproachable as Everest.
Fortunately, you have a tool available to you at all times that can help you deal with this: meditation. The benefits of meditation are numerous (and there are many, many books out there that detail them), including everything from boosting immune function to decreasing anxiety to actually increasing your gray matter. One of those many benefits is helping with insomnia.
In a study performed by Dr. David S. Black and others, a group of older adults with sleep problems were introduced to mindfulness meditation through six two-hour sessions. By the end of these sessions, this group showed meaningful improvement with insomnia.18
If meditation seems foreign to you (and, if that’s the case, you’re in the vast majority, as less than 15 percent of Americans meditate),19 it’s likely because you’ve heard that meditation is difficult or that it requires you to completely blank your mind. Ariel Garten, creator of Muse, a headband that assists in meditation, clarifies that it isn’t about emptying your mind, but rather, “training your mind to be aware in the present moment.”20
She told me that you can choose any time and any place to meditate and that you can feel the benefits from it with as little as three minutes spent with eyes closed, taking deep breaths and then releasing those breaths, counting as you go. Another tool she advocates is focused attention, a super-simple process of placing all your attention on your breathing. When your mind wanders from your breathing (as it invariably will), just notice this and bring it back. This technique promises to demystify meditation for anyone who thinks you need to be a Zen master to get anything out of it. Few of us are capable of locking our focus on one thing for an extended period, so it’s good to know refocusing is equally valuable.
When you regain your attention on your breathing, Garten says, “you’re exerting an important skill—you’re learning to observe your thinking. You’re not caught up in your thoughts, but you’re in
