Science Explains Why Hugs Bring Happiness: The Key Role of Temperature.
According to ТСН: Hugs are a complex physiological phenomenon where pleasant sensations are caused not only by emotions but also by the physiological aspects of our body. Research published in the journal Trends in Cognitive Sciences shows that warm contact is crucial for our self-awareness and mental stability.
Evolutionary Connection: From Survival to Love
The ability to feel heat and cold evolved as a protective mechanism against environmental dangers. As co-author of the study Laura Kruchanelli notes, thermoreception is one of the oldest ways our bodies communicate with the brain.
The first signals of comfort we receive are still in the womb, and later through the warm touches of our parents. This thermal experience shapes our sense of wholeness. When we embrace someone, the brain receives two important impulses: tactile (touch) and thermal (warmth), enhancing the sense of our body and groundedness.
The Neurobiology of the 'Hormone of Happiness'
Why do warm touches have a calming effect? This can be explained as follows: warmth activates specific nerve fibers in the skin – C-tactile afferents. These signals are sent to the insular cortex of the brain, causing a powerful release of oxytocin – a substance known as the 'hormone of love' or 'hormone of trust.'
This process reduces stress levels, improves overall well-being, and brings comfort.
The Impact on Mental Health
Scientists emphasize that disturbances in body perception often accompany depression and eating disorders. Co-author of the study Gerardo Salvato states that studying the reaction to temperature can help better understand complex conditions, such as the aftermath of a stroke, when a patient loses their sense of limb as their own.
In addition to medical aspects, researchers stress the importance of studying thermoreception in the context of climate change. Global warming may affect our mood and daily stress levels through constant temperature fluctuations.
An Interesting Fact About Kisses
Other forms of intimacy also have deep roots. Recent studies have shown that the habit of kissing originated in the animal kingdom about 17-21 million years ago and was common among many species, from primates to insects.
It should be noted that pets can support the emotional well-being of their owners.
Research indicates that living with a dog, especially during adolescence, can not only improve one's emotional state but also bring changes in the gut microbiome.
The psychological and physiological benefits of hugs and closeness become especially relevant in today's world, where stress and anxiety have become common companions. Understanding these processes allows us to seek new ways to improve the quality of life and support mental health.
