What’s the Difference Between SI3 and BL62?
Both acupoints are frequently confused because they both improve headaches and are effective for nervous system stabilization. However, SI3 is the “upper body specialist” that solves problems in the upper body, especially the neck and head area, while BL62 is the “nervous system stabilization specialist” that helps those suffering from insomnia and dizziness. Since their locations are on opposite body parts—the finger and the ankle—you should approach them based on your specific body area.
Understanding SI3 in Depth
Exact Location
The acupoint is located on the outer side of the little finger, in the depressed area at the boundary where skin color changes, right behind the fifth metacarpophalangeal joint (the second joint of the finger). When you make a light fist, a crease forms under the finger—use the end of this crease and the finger joint as reference points to locate it. Since it covers only about 0.1 cun (a very small area), precise location identification is important.
Recommended For
This acupoint is especially effective for those with stiff neck muscles or cervical disc discomfort, chronic headaches and migraines, frequent eye fatigue and eye pain, tinnitus or ringing sounds in the ears, text neck syndrome from smartphone and computer use, and lower back pain, particularly in the mid-to-lower lumbar region.
Acupressure Method and Tips
Using your thumb or the tip of a pen, press firmly for 3–5 seconds and release, repeating 10–15 times. Maintain a pressure level of “pleasantly painful,” but start with gentle pressure and gradually increase intensity. Stimulate twice daily—morning and evening—or up to 3–4 times daily during acute neck pain. Pressing both hands together, rather than just one side, helps balance your entire body.
Understanding BL62 in Depth
Exact Location
The acupoint is located about 0.5 cun (approximately 1.5 cm) below the lateral malleolus (outer ankle bone). Find the protruding bone on the outside of the ankle, then locate the depressed area about one finger width below it. When you gently bend your ankle inward, a more distinct hollow becomes visible, making acupressure more accurate in this position. Both feet have this acupoint.
Recommended For
This acupoint is excellent for those with insomnia—difficulty falling asleep or frequent waking—restlessness even when lying down, tension headaches with heavy head sensation, frequent dizziness or vertigo, ankle pain or frequent ankle sprains, nervousness, and psychological anxiety from stress. It also promotes blood circulation in the lower body and helps relieve cold hands and feet.
Acupressure Method and Tips
Lie down, bend one knee slightly, and apply gentle pressure with your thumb. Press for 3–5 seconds at a time, maintaining consistent medium pressure rather than excessive force. Repeat at least 10 times, and if you have insomnia, apply pressure 30 minutes before bed for best results. Stimulating between 10 p.m. and midnight is especially effective, as it regulates kidney energy and promotes deeper sleep. Press both feet, starting with the left side, which is technically easier.
Key Comparison Summary
| Item | SI3 | BL62 |
|---|---|---|
| Primary Effects | Neck pain, headaches, tinnitus, eye pain, lower back pain | Insomnia, headaches, dizziness, ankle pain |
| Body Area | Upper body focus (neck, head, eyes, ears) | Nervous system, lower body (ankle, legs) |
| Location Difficulty | Difficult (very small area) | Moderate (clear bony landmarks) |
| Pressure Intensity | Strong pressure recommended | Medium pressure recommended |
| Best Time to Stimulate | Morning/evening (immediately for neck pain) | Before bed (10 p.m.–midnight) |
| Repetitions Per Session | 10–15 times | 10–20 times |
| Best For | Acute headaches, neck stiffness | Chronic insomnia, anxiety |
Combined Stimulation Creates Synergy
When you stimulate both SI3 and BL62 together, you achieve a “yin-yang balancing” effect that regulates energy throughout your upper and lower body. This is especially effective for people whose upper body feels stiff from stress while their lower body feels unstable. The method is to first stimulate BL62 on both ankles for 3 minutes, then press SI3 on both hands for 3 minutes. This stabilizes your nervous system, releases upper body tension, and improves blood flow to the brain, simultaneously relieving headaches and insomnia. Practice this 15-minute routine 3–4 times weekly between 7 p.m. and 10 p.m., and you’ll notice changes within a week.
Conclusion: Selection Guide by Situation
Choose SI3 when: Your neck and shoulders feel stiff, you experience a sudden headache, your eyes feel tired and heavy, or your head feels weighted down after computer work. Use SI3 when you need immediate pain relief.
Choose BL62 when: You toss and turn all night unable to sleep, you feel dizzy or physically unstable during the day, your ankles frequently sprain or you have cold hands and feet. Use BL62 when you need nervous system stabilization and long-term improvement.
Optimal combination: It’s ideal to awaken your upper body with SI3 in the morning and calm your nervous system with BL62 in the evening. These two acupoints complement each other’s opposite functions, so using them together provides complete body balancing.
