In essence, arm encircling (even hand touching) will send a signal to relieve stress to the brain. Fields said: "As the skin moves, the stimulation of baroreceptors increases the activity of vagus nerve and finally relaxes your nervous system."
improve immunity
The nervous system in Buddhist countries, including lower heart rate and more relaxed brain wave patterns, may help to alleviate the effects of colds. A psychological science study on 20 14 found that the form of social support is hug. Among those who are initially stressed by interpersonal conflicts, hugs seem to provide a buffer between conflict-related stress and the risk of respiratory infection.
"Stress hormones, including cortisol, decrease and natural killer cells increase," Field said. They can kill bacteria, viruses and even cancer cells. "
Sleep better
Do you hug each other before sleeping with your lover? According to the National Sleep Foundation (NSF), as many as 63% of American couples sleep in separate beds. If you need space to have a good rest, that's fine, but try to hug secretly before going to bed. According to the National Science Foundation, just 10 minutes of touching can help you sleep better.
A little touch during the day can also improve your sleep and sensory experience.
"Many people get massages and practice yoga because of pain," Field said. We found that behaviors involving skin activities can reduce the amount of neurotransmitters that cause pain, thus alleviating pain.
The whole body is full of happy hormones.
The biochemical function of touch also includes the increase of serotonin (the natural antidepressant and analgesic neurotransmitter in human body) and oxytocin (phenylethylamine).
There is also good news for couples: a study published in Psychological Science 20 17 shows that the higher the oxytocin level, the stronger people's perception of their partner's response and gratitude, and the richer their love experience. As we all know, oxytocin plays an important role in the relationship between mother and child, as well as in the relationship between adults.
