In clinical practice, I often see office workers whose lower backs ache after hours at a desk. Between writing code, attending meetings, and meeting deadlines, they can spend much of the day barely moving.
The discomfort may begin as stiffness, but it can become a recurring problem. My starting advice is simple: give the body regular opportunities to move. Brief walking breaks, gentle exercises, and appropriate strengthening can help make movement part of even a busy day.
Traditional Chinese medicine (TCM) also offers approaches to managing stiffness and supporting overall well-being, including acupoint stimulation and dietary therapy.
Effects of Prolonged Sitting
Prolonged sitting can have wide-ranging effects on the body, influencing the nerves, brain, and metabolism.
Nerve Compression
After sitting for a long time, posture often leans forward, which can cause muscle tightness and soreness and increase pressure on the spine.
Over time, forward leaning may lead to a herniated disc, which can then compress nearby nerves.
When nerves around the lumbar or sacral spine are compressed, pain may radiate from the lower back down the leg, causing numbness, shooting pain, or an electric shock sensation.
If the cauda equina nerves become compressed, more severe symptoms can develop, such as muscle wasting in the legs or loss of normal bladder and bowel control. In such cases, medical attention should be sought as soon as possible.

Reduced Cerebral Blood Flow
Some people feel mentally dull or less focused after sitting for long periods.
Increased Risk of Metabolic Disorders
People who sit for long periods are often found to have fatty liver or elevated blood lipid levels during routine health checkups.
In this context, phlegm-dampness does not refer only to the phlegm coughed up from the respiratory tract.
It may also be understood as metabolic waste that has not been properly processed or eliminated. Over time, accumulation may manifest as abdominal obesity, abnormal blood lipids, or fatty liver.

Break up Long Sessions of Sitting
One of the main problems with prolonged sitting is that it keeps the body inactive for extended periods. Circulation in the lower limbs slows when the muscles are inactive. As a result, the lower back can become stiff, and the mind may feel sluggish.
The following movements are designed to interrupt prolonged sitting, activate the muscles, and relax the posterior fascial chain. These effects reengage the legs, lower back, and brain.
Wu-Style Half Squats
I recommend that people who sit for long hours make it a habit to move for one minute every 20 minutes. The squat does not need to be deep; the key is to safely and gently activate the thigh and gluteal muscles.
For people with knee degeneration or frequent knee pain, regular squats may not be suitable if done with too much depth. An option is to modify the movement into a gentler half squat.
Step 1: Stand with both feet naturally apart and keep the body upright.
Step 2: As you squat down, move the hips backward as if you are about to sit on a chair, while keeping the back as straight as possible.
Step 3: Allow the knees to move slightly past the toes naturally, but do not forcefully push them forward.
If the knees feel tight or painful, reduce the range of motion. You may also hold on to a chair for support.
One key point of this movement is to place both hands in front of the knees while squatting down. As you stand back up, gently slide your palms upward along the knees.
This hand movement helps remind the body to rise slowly. From a TCM perspective, it also helps guide qi and blood around the knees upward in a smoother direction.
Some patients report that this method feels more comfortable to perform than a regular squat and places less pressure on the knees.
The squat should be performed slowly and does not need to be deep. The goal is simply to gently engage the thighs, hips, and knee joints.
Tap Supporting Middle (Wei Zhong, BL40)
The Supporting Middle acupoint is located at the back of the knee, in the center of the popliteal crease.
In TCM, this acupoint is often used to support the management of lower back soreness and discomfort in the lower limbs.
For daily care, gently tap the Supporting Middle acupoint on both legs using your palm or a loose fist, about 50 to 100 times on each side, until the area feels slightly warm and mildly sore.
Tapping may help relieve tension in the lower back and the back of the legs.
However, if lower back pain is accompanied by noticeable leg numbness, an electric shock sensation, or weakness when walking, medical evaluation should be sought promptly.
Stretch the Posterior Chain
After tapping the Supporting Middle acupoint, gently stretch the muscles along the back of the legs.
According to TCM meridian theory, the Bladder meridian runs along the back of the body, extending from the head and neck down through the back, lower back, and the backs of the legs.
This pathway roughly corresponds to the posterior chain, which links the calves, hamstrings, hips, and lower back.
When the muscles at the back of the legs become too tight, they can tug on the pelvis and strain the lower back, leading to stiffness in the lower back and weakness in the legs.
A slant board may be used to assist with stretching and help relieve tension along the lower back and the posterior side of the lower limbs.
When standing on a slant board, keep the heels firmly planted and the body upright. Allow the backs of the calves to stretch gradually, then slowly extend the stretch toward the hamstrings and hips.
The angle should not be too steep at first, and the stretch should not be forced to the point of significant pain. Older adults may hold on to a wall or the back of a chair for support.
If numbness, tingling, knee discomfort, or lower back discomfort occurs, reduce the angle or stop the movement.
Leg Raises
People who sit for long periods often develop abdominal fat. The extra weight around the abdomen can shift the body’s center of gravity forward, increasing the strain on the lumbar spine.
The core muscles function like a support belt for the lumbar spine. If the abdomen is soft and the core is weak, the lumbar spine has to bear more of the load.
The Epoch Times
Exercises such as leg raises can help activate the abdominal core muscles and reduce the burden on the lumbar spine.
Step 1: Lie flat on the floor with both legs together and straight. Slowly raise both legs to about 30 to 45 degrees, hold for about seven seconds, then slowly lower them back down.
Step 2: Focus on maintaining control throughout the movement, ensuring it feels stable without straining the lower back.
People with a larger abdomen or weaker core strength can begin with a smaller angle and a shorter hold.
When combined with weight management and a balanced diet, strengthening abdominal support can help improve lumbar spine stability.
A Traditional Soup for Dietary Support
In practice, I also see older patients with poor muscle strength and significant spinal problems. Some have severe difficulty walking. Their care may include treatment, rehabilitation, and adjustments to daily habits, with dietary therapy used as an additional form of support.
The following soup combines kudzu root, Chinese yam, poria, and black soybeans. In TCM, these ingredients are traditionally used to support digestion, address dampness, and nourish the body.
Kudzu root is traditionally used to ease muscle tension; Chinese yam supports the spleen and kidney systems; poria supports the spleen and the handling of fluids; and black soybeans are traditionally associated with nourishing the kidney system.
The TCM kidney system encompasses functions related to bones, marrow, and vitality. It is broader than the anatomical kidneys. These traditional uses explain the recipe’s place in TCM dietary therapy; the soup should not be presented as a treatment for nerve compression or spinal damage.
Kudzu Root, Chinese Yam, Poria, and Black Soybean Soup
Preparation: 10 minutes, plus 4 to 6 hours of soaking
Cooking: 60 to 90 minutes
Yield: Approximately 6 small servings, depending on evaporation
Ingredients
-
0.5 ounces (15 grams) kudzu root slices
-
1.1 ounces (30 grams) dried Chinese yam (shan yao)
-
0.5 ounces (15 grams) poria
-
1.1 ounces (30 grams) dried black soybeans
-
2 slices fresh ginger
-
6 cups water
Optional additions traditionally selected according to TCM patterns include 0.4 ounces (10 grams) lotus seeds for fatigue or restless sleep, or 0.1 ounces (3 grams) dried tangerine peel for bloating associated with phlegm-dampness.
Instructions
-
Soak the black soybeans in water for 4 to 6 hours, or overnight in the refrigerator. Drain and rinse.
-
Briefly rinse the kudzu root, Chinese yam, and poria.
-
Put all ingredients in a large pot, including any optional additions. Add the water.
-
Bring to a boil, reduce the heat, and simmer covered for 60 to 90 minutes, until the beans are fully tender.
-
Strain out tough herbal pieces if desired and serve warm.
Use black soybeans rather than ordinary black beans, and obtain herbal ingredients from a reputable supplier. If trying the soup for the first time, begin with a small portion and observe how your digestion responds.
Pregnant people, those with impaired kidney function or undergoing cancer treatment, and anyone taking regular medication should consult a qualified clinician or TCM practitioner before using the herbal soup regularly. Individual ingredient choices should reflect medical history and TCM assessment.
The most useful change can begin before the next meal or exercise session: stand up and take a short walk. Repeated throughout the day, small movement breaks turn caring for the back into a habit that fits everyday life.
If lower back pain is accompanied by noticeable leg numbness, an electric shock sensation, weakness while walking, numbness in the perineal area, or abnormal bladder or bowel function, medical evaluation should be sought as soon as possible. TCM herbs can be purchased from licensed or reputable Chinese medicine shops to help ensure quality and authenticity.
