EDITOR’S SUMMARY: Fascia is a continuous, dynamic network that supports your body’s structure, movement, and internal communication—yet its role has long been overlooked. From elasticity and fluid balance to sensory signaling and adaptation, this tissue responds directly to how you move, rest, and nourish yourself. While research continues to uncover its full significance, caring for it through varied movement, adequate hydration, and regular bodywork such as stretching or massage may help preserve mobility, resilience, and function over time.

From your first morning stretch to curling up at night, you can thank the unsung hero of your body: fascia. This intricate, web-like network of fibers runs throughout your body from head to toe. One continuous piece, it works with (and within) bones and muscles, tendons, ligaments, and organs to quite literally hold you together. You might’ve seen this material in the kitchen—it’s the thin, whitish layer you can peel away from a chicken breast, the marbling in a cut of beef, or, for the vegetarian crowd, something akin to the pith of an orange that holds everything in place. Its importance is only now being recognized, as it turns out that the health of your fascia is crucial to staying mobile, functional, and comfortable throughout your life.

Regardless of candles on a cake, one factor that can make you feel old is a shift in flexibility: waking up feeling “stiff,” discomfort when bending over to pick up the phone you dropped, or tweaking a muscle when reaching up high for something. Your mobility depends on healthy fascia—this is the material that must stretch, recoil, and glide for you to move with ease. The earlier you begin to care for your fascia, the longer you’ll be able to maintain a wide range of motion and function in everyday life.

Strength, Signal, and Structure

Just as a spiderweb appears fragile, its strength rivals that of steel. Your web of fascia is equally remarkable, with a tensile strength of up to 2,000 pounds per square inch—able to withstand that amount of force before breaking. Despite its vital role, for decades, fascia was regularly cut away and tossed out of cadavers in medical school, with scientists treating it more as filler than a structure worthy of study. It wasn’t until 2013 that the first textbook specifically about fascia appeared.^,

Still, this level of appreciation is long overdue, especially for a substance that holds your whole body together and accounts for roughly 40–50 pounds of your total weight. Its structural function is the reason you can be 60% water and not exist as a puddle on the ground. It’s made up of collagen—thick, strong fibers that give your body its shape; elastin—thin, flexible fibers that can stretch up to 150 percent of their length; and “ground substance,” or hyaluronan, which acts as a lubricant between fascial layers, allowing them to glide smoothly.

Fascia runs throughout your body, including beneath and attached to the skin, similar to a wetsuit. Structurally, it functions via the principle of tensegrity—a system in which rigid elements and continuous tension balance each other. In his book “Anatomy Trains,” manual therapist Tom Myers mapped out 12 fascial routes, or “lines”—8 through the lower body and trunk, plus 4 arm lines running from the spine to the fingertips. For example, the spiral line connects the two sides of your body, running from your feet to your skull and crisscrossing near your belly button, providing balance and stability for walking, twisting, and rotational movements. These interconnected pathways help explain why tension in one area can show up as pain in another.

Among fascia’s many important functions is its ability to sense and adapt to what you need, meaning your repetitive positions and movements shape your connective tissue over time. Cells known as fibroblasts help produce tissue in response to these demands. This is why, for example, champion javelin thrower Thomas Röhler was found to have fascia measuring 3 mm deep in his right pectoral muscle—three times thicker than in his left. As fascia expert Dr. Robert Schleip, who conducted the measurements, noted in a research forum, it’s not surprising for a frequently used muscle to grow larger, but such a pronounced difference in the surrounding fascia was unexpected. This suggests that as muscle develops, the surrounding supportive fascia adapts alongside it.

Even the understanding of how fascia grows has changed in recent years. In a 2018 study led by Italian Professor Carla Stecco, her team discovered an entirely new type of cell they dubbed “fasciacytes.” It was previously thought that fibroblasts generated new connective tissue, but Stecco’s research found that fibroblasts are responsible for producing collagen and elastic fibers, while fasciacytes produce hyaluronan. If this component is not functioning properly, it can cause pain and restricted movement. Fasciacytes appear to line the boundaries of different fascial layers—positioning them to detect when more hyaluronan is needed and produce it accordingly. Your fascia is also piezoelectric, meaning the tissue can generate small electrical charges. Collagen—your body’s most abundant protein—plays a central role in this property and is involved in virtually every movement you make.

“Every time we move, stretch, or even shift in our seats, we create mechanical stress that deforms the collagen fibers in our fascia. This deformation generates tiny electrical currents . . . These currents help guide biological processes, especially in bones. For example, when you land from a jump, your bones bend ever so slightly, generating piezoelectric charges in the collagen. These charges signal bone cells to strengthen and grow, reinforcing the areas under stress. This is why weight-bearing exercise is so important for bone health–it literally electrifies your bones!”

Where the Body Feels and Responds

This piezoelectric quality may be part of the mechanism by which acupuncture works. In her team’s research, neuroscientist Dr. Helene Langevin, former director of the National Center for Complementary and Integrative Health, discovered that about 80 percent of acupuncture points correspond to areas where connective tissue planes converge—often compared to intersecting roads. This could be the physiological “Western” explanation aligning with the Eastern focus on energy and meridians. While the exact mechanism of signaling that occurs via an acupuncture needle is still not fully understood, whatever communication it initiates may have an effect both spatially “(connecting different parts of the body) as well as across physiological systems (connective tissue permeates all organs and surrounds all nerves, blood vessels, and lymphatics).”

When acupuncture needles are removed, your body’s resistance is known as “needle grasp.” While it was long thought that this resistance was due to muscles contracting, Langevin’s research suggests it is more likely caused by fascia wrapping around the needle. Her team found that once inserted, needles that were rotated produced greater resistance upon removal than those left still. Ultrasound imaging shows fine connective tissue fibers wrapped around the needle during rotation. Those same areas also reveal measurable changes in connective tissue architecture—indicating that an acupuncture session can physically alter fascial structure.

As if electrical signaling wasn’t enough, your fascia is also viscoelastic. This means it both springs back like a solid (the “elastic”) and slowly adapts like a fluid when gentle forces are held over time (the “viscous”). The elastic aspect allows you to jump and land, with tissue stretching quickly and returning to its original shape. The viscous aspect comes into play with sustained pressure—such as during a massage or longer stretches like yoga poses. You might notice that a quick stretch feels different from a long one because your connective tissue relies on different properties for each.

Fascia has since surpassed skin as your body’s largest sensory organ, with approximately 250 million nerve endings compared to skin’s 200 million. The release and relief felt after a yoga session or a massage are not always purely physiological. Because fascia is both your largest sensory organ and one continuous network—extending from your toes to your brain and gut (often referred to as your “second brain”) and facilitating communication—some experts believe emotions may be stored within this versatile tissue.

Whatever causes stress—a piece of bad news, a deadline you just remembered—you’ve probably felt it somewhere in your body. It could be a “pit” in your stomach, a knot in your throat, or tension in your shoulders. Of course, this happens with good news, too—like “butterflies” in your stomach when you’re excited or tearing up when moved. Feeling the internal state of your body is known as interoception—a sense that covers everything from thirst and hunger to nerves before a presentation or test. While interoception is an “accepted” sense, there is still disagreement on whether parts of your body are so connected to emotions that those sensations can be alleviated through treatments like myofascial release (MFR).

Similar to massage, MFR focuses on specific areas of restriction within the body. Where a Swedish massage typically uses consistent pressure and flowing movements for relaxation, an MFR therapist concentrates on areas where the fascia shows restriction. The pressure on each point can be deeper and is sustained longer than in a traditional full-body massage, held until the restriction begins to release. The therapist then follows the fascia’s loosening to the next restriction, and so on, as your body “communicates” its needs.

There are anecdotal reports of people experiencing emotional relief during fascial release, but studies have yet to support the idea that these are directly causal. Because of the complexity of emotions and the makeup and pervasiveness of fascia, it can be difficult to pinpoint how they directly influence one another. It’s possible that emotions or traumas can get “stuck” in your bodily tissues, especially since trauma or long-term stress can result in chronic muscular tension as the body attempts to protect itself, known as “armoring.” But it’s also possible that myofascial release feels emotionally meaningful because slow touch strongly affects the body’s interoceptive and nervous system pathways.

Most of the nerve receptors in your fascia are sympathetic nervous system receptors, and many of these nerve endings are vasoconstrictive, controlling blood flow, so it makes sense that “subtle changes in skin temperature often reflect acute and chronic changes in emotions.” While randomized controlled trials haven’t shown that emotions “live” inside your fascia, these tissues are so closely linked to the brain that, as Andrew Taylor Still, the founder of osteopathy, believed, “All fascial tissues should be treated with the same respect as if dealing with ‘the branch offices of the brain.’”

If connective tissue is so important, is more always better? Not necessarily. Tissue that develops in an organized manner in response to exercise reflects a healthy adaptation. When it forms excessively and in a disorganized way—due to scarring or chronic inflammation—it’s known as fibrosis. If this condition progresses, it can lead to organ failure and even death. When it comes to your fascia, it’s not quantity, but quality—making how you care for it essential.

Movement as Maintenance

Keeping your fascia loose and lubricated is important, and that can be achieved in several ways. Getting adequate sleep and hydration is always important, but especially so for connective tissue, which (when young and healthy) is composed of approximately 70% water. The regeneration it undergoes, including the secretion of human growth hormone, only occurs during deep sleep. General hydration guidelines, such as drinking roughly half your body weight in ounces, can be a helpful starting point, but don’t forget your electrolytes, as they help your cells more effectively hold moisture. This is where some water-rich foods can be helpful: watermelon, celery, and cucumber—each contributing hydration along with supportive compounds like natural electrolytes and silica, which support elasticity and structural integrity.

Protein is the most important building block in your connective tissue, and the amino acids it requires cannot be made by the body, so dietary intake is essential. Animal protein provides a complete source, while vegetarians can obtain adequate amounts from legumes and lentils with careful planning. Vitamin C is vital for collagen synthesis and is often more readily obtained from vegetables like spinach, parsley, and peppers, which can contain higher levels than many fruits. Zinc, found in foods like nuts and legumes, is a key mineral for synthesizing collagen and protein. Copper (via fish, cocoa, liver, nuts, and seeds—ideally not all in the same bite) and sulfur (found in cruciferous vegetables, onions, and garlic) are necessary to create the “crosslinks” (fibers) that connect new collagen and elastin fibers to each other when fascia is stimulated.

Nutrition and rest matter, but the way fascia primarily hydrates is through movement. Think of a sponge and how dribbling water on it won’t reach every part, whereas squeezing it allows moisture to spread throughout the material. To this end, Schleip penned a book titled “Fascial Fitness: How to Be Vital, Elastic and Dynamic in Everyday Life and Sport,” in which he lays out a plan that requires only 20 minutes of your week in the form of two 10-minute sessions. He recommends six exercises in a specific sequence, beginning with foot rolling and working your way through your legs, your front and back fascial lines, your waist and sides, followed by the shoulders, and a neck-back combo. The only “equipment” necessary is a tennis ball and a chair.

The exercises are designed to strengthen and nurture what Schleip calls the four functions of fascia: movement, communication, supply, and shape. The function of shape is as it sounds—giving structure to what would otherwise be an unorganized mass of organs, muscles, and bones. Fascia’s relationship to movement is that it maintains tension and elasticity, as well as supporting energy storage and transfer. The function of “supply” is about moving fluid and nutrients throughout your body, and communication refers to the transmission of stimuli and information. The corresponding exercises involve what he refers to as spring, revive, feel, and stretch.

“Spring” encompasses motions like hopping or swinging the upper body, promoting elasticity. Think of childhood activities like skipping and playing hopscotch—these increase elastic recoil capacity, or your tissues’ ability to return to their original shape after being stretched. This is one reason children tend to have much more malleable fascia than adults. Rebounders (small trampolines) have become increasingly popular and can also support cardiovascular exercise, but you don’t need equipment. Schleip’s jumping protocol involves gentle hops with a goal of landing as quietly as possible, only using (walking) poles if necessary for support.

“Revive” is designed to rejuvenate fascia via squeezing, as this is how your body dynamically hydrates—essentially wringing out old fluid and metabolic waste, allowing fresh fluid to fill the space. Dynamic hydration becomes especially important as you age, since studies have shown that by age 60, the water content of your fascia may drop from 70–80 percent to 50 percent. Professional massage can help in this endeavor and offers benefits beyond fascia, but a daily massage would be quite the financial investment. Instead, Schleip’s program begins with self-massage, often using a rubber ball, tennis ball, or foam roller under your feet. You may meet resistance and discomfort with this type of work, at least initially. In this situation, one tip physical therapist Dr. Kelley Starrett offers is to take a slow inhale (around four seconds), allowing the muscle to gently contract, holding for four seconds while applying pressure with the roller or ball, then exhaling (longer than your inhale) and allowing the muscle to relax. This sequence helps signal safety to your nervous system and can reduce resistance after a few repetitions.

“Feel,” in the quartet of workout principles, is characterized by awareness of your movement and coordination. This means being present with your body, staying connected rather than distracted during exercise. “Stretch” is fairly self-explanatory, except that when it comes to fascia, longer stretches are thought to be more beneficial, as it takes time to release and refresh tissue—something for which there is no shortcut. Stretch not only helps invigorate and hydrate your fascia—emerging research suggests it may also influence broader physiological processes, including those related to cancer.

In her lab, Langevin has worked with rodents in a practice she dubs “rat yoga.” In her 2018 study, mice were injected with breast cancer cells and divided into two groups: one non-stretch and one where the mice were put into a yoga-like gentle stretch for about ten minutes a day. After four weeks, the tumors of the mice who stretched were 52 percent smaller than those in the non-stretch group, without drugs or other treatment. Regarding Langevin’s results, it has been suggested that many people develop cancer but don’t die from it: “Whether we die from it depends mostly on how fibrotic is the connective tissue around it.”

In the case of cancer, if connective tissue surrounding the tumor builds up excessively, it can act “almost like scaffolding that helps a tumor take root, connect to blood vessels, and grow.” What many of the biomarkers in the study showed was that “stretching appeared to do something extraordinary: it helped the body ‘turn up’ its cancer-fighting immune response while simultaneously ‘turning down’ the chronic inflammation that helps cancer thrive.” Considering that approximately 45 percent of worldwide deaths in developed countries are attributed to fibrotic diseases, this finding has potential beyond cancer.

Fortunately, rejuvenating your fascia is very doable, with no fancy equipment or gym membership required. Schleip even proposes the idea of adults using playground equipment to awaken movement patterns you may have left behind in childhood but that still play a role in restoring fascia. His book includes a playful photo of Schleip, now in his 70s, on a playground rope climbing structure, hanging by his arms and legs. This, of course, should be approached with caution and common sense—no dangling upside down from a jungle gym on day one.

In some parts of the world, like the “Blue Zones”—areas where people regularly live past 100—physical activity such as lifting loads, bending, squatting, and walking steep slopes is woven into daily life. For example, in Ikaria, Greece, nonagenarians (those over age 90) reported spending less than three hours per day sitting—far less than the roughly 9.5 hours per day reported among older adults in the United States. These environments demand a lifestyle that includes activities like “walking to commute, working labor-intensive occupations, participating in outdoor hobbies, and navigating complex terrain with constant exposure to uneven surfaces.”

It’s not just the movement but how they move—reaching, bending, adjusting to slopes and rocky paths, and engaging leg and foot muscles in varied ways to maintain balance. These demanding motions help maintain fascial hydration and elasticity—a stark contrast to the American perception of aging as inherently fragile. These same types of movements—walking and running, climbing and swinging, throwing, squatting, carrying, digging, and playing—form the foundation of a healthy, resilient musculoskeletal system, no matter where you live.

If you’re looking for more real-time guidance, there are many fascia-focused exercises available online. Some involve dance-type movements, others focus on more standard workouts with minimal equipment, and some are even specific to facial fascia (say that three times fast), where the movements and self-massage are geared toward the muscles in your face and neck.

Since your fascia can both generate and conduct electrical signals, is one continuous piece, and runs throughout every part of your body, it’s worth devoting time to caring for this remarkable system. Attention to it can help ensure your mobility and flexibility—key components of freedom and independence as you age. The research is still catching up—but your body doesn’t need to wait for it.
