Shi Mian Lost Sleep

What does Shi Mian do?

Shi Mian calms the spirit (Shen) and promotes sleep, and alleviates pain in the heel and sole — an extra point on the bottom of the heel, and the classic point for insomnia.

• Calms the Shen and promotes sleep — the point’s whole reputation; its name literally means “Lost Sleep” (i.e. insomnia)
• Alleviates pain in the heel and sole of the foot — the local action, the point sitting on the heel

The name is the indication. “Shi Mian” means Lost Sleep — the Chinese term for insomnia — and this extra point (coded EX-LE-15 / M-LE-5) is, traditionally, the point of first choice for it, whether needled, warmed with moxa, or simply pressed, tapped or massaged at the centre of the heel. The idea, in classical terms, is of drawing the yang and the spirit downward at day’s end (the sole being the lowest, most yin point of the body), settling an over-active mind for sleep.

A local heel point too. Sitting on the sole of the heel, it doubles as a local point for heel and plantar pain — plantar-fasciitis-type heel pain and sole pain — used where the ache is.

On the name. “Shi Mian” — Lost Sleep, insomnia, as noted above.

What is Shi Mian used for?

Shi Mian is used above all for insomnia, and locally for heel and sole pain. These follow directly from its two recorded actions.

• Insomnia — difficulty falling or staying asleep; the point’s defining use
• Restlessness and an over-active mind at night — the spirit-calming use
• Heel pain and sole pain — including plantar-fasciitis-type pain, the local use

An accessible point. Because it works by pressure and moxa as well as needling, Shi Mian is one of the extra points a person can be shown to press or warm themselves at bedtime — a genuinely usable self-care point, unlike most of the library.

An honest note. Persistent insomnia deserves proper assessment — it can stem from stress, pain, depression, sleep apnoea, thyroid disease, medication or caffeine, and treating the cause matters more than any single point; good sleep habits (a regular schedule, a dark cool room, limiting screens and caffeine) are the foundation. Heel pain that is severe, persistent, or follows an injury warrants assessment. This record documents classical use only.

How it is combined. With HT-07 Shen Men, SP-06 San Yin Jiao and An Mian (another “peaceful sleep” extra point behind the ear) — the classical insomnia combination. All held here.

Where is Shi Mian located?

Shi Mian is on the bottom of the heel, at its centre.

• On the sole, in the centre of the heel — on the midline of the foot, at the middle of the heel pad
• Commonly located at the midpoint of the line from the heel-sole to the back of the heel, directly below the ankle

The centre of the heel. The point sits at the middle of the fleshy heel on the sole — an easy landmark to find and to press. Some traditions place a second location on the back of the heel; the sole-centre location is the common one.

On the name. “Shi Mian” — Lost Sleep, as noted above.

How is Shi Mian needled?

Our own record states perpendicular insertion of 0.3–0.5 cun, and notes that moxibustion may also be used. What follows is a neutral record of what the reference literature documents. It is not instruction, and this page does not teach technique.

• Angle and depth as recorded: perpendicular, 0.3–0.5 cun. The skin over the heel is thick, so insertion can be uncomfortable and calls for a firm, decisive technique.
• Moxibustion: recorded as usable — and warming the point with moxa, or simply pressing it, is a common and gentler alternative to needling for sleep.
• Regional anatomy: the point lies on the thick heel pad over the calcaneus (heel bone); the medial and lateral plantar nerves and vessels run more toward the sides of the sole; the heel bone is immediately deep.

Hazard, stated proportionately. This is a low-hazard point: no cavity, no organ, bone beneath thick skin. The main issue is comfort — the heel skin is thick and needling is felt sharply. Our record carries no arterial caution at Shi Mian. As with any foot point, clean technique matters (the sole picks up dirt).

What is not claimed. No study measuring a safe depth at Shi Mian could be located, and none is needed at this shallow depth over the heel bone. No case report naming Shi Mian was located.

Is there research on Shi Mian, and what should a reader know?

No trial isolates Shi Mian. Where it appears it is one component of an insomnia protocol, and a study that includes a point in a protocol is not evidence about that point.

What this page can state with confidence. Shi Mian (“Lost Sleep”, EX-LE-15) is an extra point at the centre of the heel whose name is the word for insomnia — the traditional first-choice point for it, workable by needle, moxa or simple pressure, which makes it a rare genuinely usable self-care point. It doubles as a local point for heel and sole pain.

A note on sleep. Persistent insomnia is best addressed by finding and treating its cause and by good sleep habits; a heel point is a small adjunct, not a cure.

A note on searching for it. Shi Mian is coded EX-LE-15 (older texts: M-LE-5); “Shimian” also returns place and personal names, and the word itself means “insomnia”, so searches are noisy. Any claim should be checked against what a study actually used.
