5 surprising benefits of #walking: Any physical activity is a boon to your overall health. But walking in particular comes with a host of benefits. https://bit.ly/3uyNvhI #HarvardHealth

The next time you have a check-up, don’t be surprised if your doctor hands you a prescription to walk. Yes, this simple activity that you’ve been doing since you were about a year old is now being touted as “the closest thing we have to a wonder drug,” in the words of Dr. Thomas Frieden, former director of the Centers for Disease Control and Prevention.

Of course, you probably know that any physical activity, including walking, is a boon to your overall health. But walking in particular comes with a host of benefits. Here’s a list of five that may surprise you.

1. It counteracts the effects of weight-promoting genes. Harvard researchers looked at 32 obesity-promoting genes in over 12,000 people to determine how much these genes actually contribute to body weight. They then discovered that, among the study participants who walked briskly for about an hour a day, the effects of those genes were cut in half.

2. It helps tame a sweet tooth. A pair of studies from the University of Exeter found that a 15-minute walk can curb cravings for chocolate and even reduce the amount of chocolate you eat in stressful situations. And the latest research confirms that walking can reduce cravings and intake of a variety of sugary snacks.

3. It reduces the risk of developing breast cancer. Researchers already know that any kind of physical activity blunts the risk of breast cancer. But an American Cancer Society study that zeroed in on walking found that women who walked seven or more hours a week had a 14% lower risk of breast cancer than those who walked three hours or fewer per week. And walking provided this protection even for the women with breast cancer risk factors, such as being overweight or using supplemental hormones.

4. It eases joint pain. Several studies have found that walking reduces arthritis-related pain, and that walking five to six miles a week can even prevent arthritis from forming in the first place. Walking protects the joints — especially the knees and hips, which are most susceptible to osteoarthritis — by lubricating them and strengthening the muscles that support them.

5. It boosts immune function. Walking can help protect you during cold and flu season. A study of over 1,000 men and women found that those who walked at least 20 minutes a day, at least 5 days a week, had 43% fewer sick days than those who exercised once a week or less. And if they did get sick, it was for a shorter duration, and their symptoms were milder.

With all of the new and emerging information on pain science, yoga students and teachers have the opportunity to apply modern research to their practices and help alleviate and prevent pain.

Preliminary research suggests that gentle movement of your nerves is vital to both managing pain and supporting the general health of your nervous system. The idea is that healthy nerves should be able to gently slide, elongate, and angulate within neural tissues (some nerves can move as much as ¾ inch) in order to adapt to different loads and minimize pressure that can worsen existing pain, alter sensation, or lead to new pain patterns. Sometimes, tone and tension around neural tissues can be a problem. These tissues are bloodthirsty and rely on an important pressure gradient around them to maintain adequate blood flow. So even small changes in tissue tension around a nerve can be enough to block nerve mobility and lead to compression that disrupts blood flow and nerve signaling back to the brain, contributing to pain.

To help you keep your nerves adaptable and protected, try the asana technique on the following pages based on an understanding of neurodynamics (the study of nerve movement through its surrounding tissues) and nerve pathways. We have the ability to alternately put tension on different ends of the nerve to create a movement of the nerve through the tissues, often referred to as nerve gliding. As you floss the nerve, you potentially allow it to move more freely so that it can communicate more efficiently with your brain. For example, the sciatic nerve runs through the back of your leg, so in Supta Padangusthasana (Reclining Hand-to-Big-Toe Pose) if you bend your knee (raised leg) and flex your foot, you’ll put tension on one end of the nerve (by your foot) and slack the other end (by your knee). This action draws the sciatic nerve and its branches toward your foot. Then, as you extend your knee and point your toes, you’ll reverse the areas of tension and slack. This action draws the branches of the sciatic nerve toward your knee. When you put these movements together you can encourage the sciatic nerve to move back and forth through its tissues more effortlessly. You also may down-regulate local inflammatory responses, restore healthy blood flow to the hard-working nerve, and encourage more efficient communication between your brain and body. Optimal signaling is crucial if you want your immune and nervous systems to function at their best, which is another reason to add nerve gliding to your repertoire.

The key to nerve gliding is to move gently within an easy range of motion. Since your target is the pain-free movement of your nerves, not of your muscles and fascia, you want very little sensation or stretch. It’s a great reminder that even in the physical body there’s clearly more to what we do than just sensations or the feel-good endorphins associated with them. Another thing I love about this approach is that, in addition to being a safe way to work with pain, it’s very accessible since it’s about simple, gentle movements.

Sequence – Neurodynamic Movement

To begin, pick a nerve you want to focus on and find a range of motion that’s accessible, pain-free, and with very little (if any) stretching sensation. Do 5–10 repetitions of the pose or this sequence once or twice a day. If you’re using these moves more preventatively, try rotating a few of them into your regular practice a couple times a week, and remember that in group classes there’s more than just stretch and sensation affecting the tissues. Happy flossing!
