Touching your face while sleeping

In bed one morning — many, many years ago now — a partner asked me if I knew that I often have my hand touching some part of my face while sleeping.

I think of this often, in fact almost every time I wake up and discover I’m doing it. The two most common scenarios are: 1) one or two fingers on my cheek or 2) my thumb and forefinger like a horseshoe around my chin.

I hadn’t realized I do that, so naturally, I did some research on it. And I find one of the reasons very interesting.

The research says:

There is a recognized correlation between sleeping with your hands touching your face and the behaviors established in the womb. This sleeping position is considered a form of self-soothing that mimics the comfort, warmth, and security experienced during fetal development.

The Womb Connection (Fetal Development)

• Early Development: Touch is the first sense to develop, with receptors forming around 8 weeks of gestation.
• Self-Soothing Behaviors: Ultrasound scans indicate that as early as the second trimester, babies frequently touch their faces and suck their thumbs for comfort.
• Space Limitations: In the third trimester, limited space causes many babies to rest with their arms flexed near their faces.
• Long-term Imprint: These early movements and positions establish a “map” of the body and create a “memory” of comfort that continues after birth.

Why Adults Sleep with Hands on the Face

• Self-Soothing and Security: This posture, sometimes called “T-Rex arms,” acts as a subconscious way to calm the nervous system.
• Comfort: Touching the face can trigger the release of neurotransmitters that create a sense of safety, similar to being in the womb.
• Sensory Regulation: It can be used to manage sensory input or reduce anxiety.

Types of “Womb” Sleeping Positions

• Fetal Position: Sleeping on the side with knees drawn up often mimics the protective, warm posture of the womb.
• “Dinosaur Hands” (T-Rex): Elbows bent with hands tucked under the chin or on the chest, often to feel secure.
• Face Touching: Resting hands on the forehead, cheeks, or covering the mouth for comfort, often to reduce anxiety.
