The "Mother Touch" Idea 🤱
The term "mother touch" usually refers to the deeply soothing and regulating effect a parent's gentle touch has on a baby or even a child. While it sounds a bit magical, science actually backs up that this is a real and very important effect!
Soothing Power: Gentle, slow stroking, often called C-tactile (CT) touch, is known to trigger special nerve fibres in our skin.
Benefits: For babies, especially premature ones, this kind of touch can lower their heart rate and reduce stress. It seems to be a built-in way for humans to feel safe and connected.
Instinct: Many parents seem to do this type of stroking naturally, often at just the right slow speed without even thinking about it!
Special Nerves for Slow Touches 🤏
Yes, we absolutely have special nerves that are perfectly tuned for very slow, light touches!
These specialised nerve fibres are called C-tactile (CT) afferents.
How they work: They are a type of low-threshold mechanoreceptor found in the skin, particularly in hairy areas.
Optimal Speed: These nerves are most sensitive and fire most strongly when a light touch moves at about 1 to 10 centimetres per second. The suggested speed of 3 cm/s falls right in the sweet spot for these nerves!
What they signal: Unlike nerves that tell you about pressure or pain, CT afferents mainly signal that the touch is pleasant or soothing. They send this calming message straight to areas in the brain linked to feeling safe and social.
So, "Mother touch" is real in terms of its scientific basis in how our nerves react to slow, gentle contact, and yes, we have C-tactile fibres specifically made to react to touches moving at about 3 cm/s!
This information is based on studies about C-tactile fibres and their role in social touch.
