The enjoyment of the feeling of weight on top of us, whether it's a cat resting on our lap or a weighted blanket, can be attributed to several scientific and psychological factors:
Comfort and Security: The sensation of weight can create a feeling of comfort and security. It might remind us of the comforting embrace of a loved one or the sense of safety we experienced as children when being held by our parents. This feeling of safety can trigger a relaxation response, reducing stress and anxiety.
Deep Touch Pressure Stimulation: The pressure from the weight, especially when evenly distributed, can provide what is known as Deep Touch Pressure Stimulation (DTPS). DTPS has been shown to have a calming effect on the nervous system, leading to the release of neurotransmitters like serotonin and dopamine, which are associated with feelings of happiness and well-being.
Vestibular Stimulation: The presence of weight can also provide gentle movement or vibrations, especially if the object on top of us shifts or breathes (e.g., a cat's purring). This can stimulate the vestibular system, which is responsible for our sense of balance and spatial orientation. Vestibular stimulation is thought to have a soothing effect on the nervous system.
Bonding and Connection: When a cat or a loved one rests on us, it fosters a sense of bonding and connection. Physical touch and closeness can trigger the release of oxytocin, often referred to as the "love hormone" or "bonding hormone," which enhances feelings of trust and attachment.
Sensory Integration: Humans have a complex sensory system, and different types of sensory inputs can be integrated to produce a harmonious experience. The weight on top of us adds to the sensory input we receive from our surroundings, creating a comforting and pleasurable experience.
Association with Positive Experiences: Over time, we might have developed positive associations with the feeling of weight on top of us, such as moments spent with beloved pets or loved ones. These positive associations can lead to a preference for this kind of physical contact.
It's important to note that individual preferences and experiences can vary. While many people enjoy the feeling of weight on top of them, some individuals might not find it as enjoyable due to personal preferences or sensory sensitivities. Additionally, the level of enjoyment may vary depending on the context, the relationship with the individual or animal providing the weight, and other situational factors.
