Rubbing your hands without oil creates more friction between the surfaces of your hands, as there is less lubrication to reduce the resistance between them. This can lead to more heat being generated and potentially causing irritation or discomfort.
On the other hand, rubbing your hands with oil reduces the friction between the surfaces of your hands, as the oil acts as a lubricant. This allows your hands to glide more smoothly against each other, reducing the heat generated and making the rubbing process more comfortable and effective.

Hand Rubbing Without Oil:
- Friction: Lower friction due to the lack of lubrication between the surfaces of the hands.
- Surface: Dry and rough, creating greater resistance and increased friction.
Hand Rubbing With Oil:
- Friction: Higher friction due to the presence of oil, which reduces the surface area in contact and creates a smoother surface.
- Surface: Lubricated and more slippery, resulting in reduced resistance and friction.
Why the Difference?
Oil acts as a lubricant, filling in the microscopic gaps between the surfaces of the hands. This reduces the actual surface area in contact, which in turn decreases the frictional force. The slippery nature of oil also allows the hands to slide more easily over each other, further reducing friction.
