For the first time, it has been shown that holding hands can synchronize brain waves and relieve pain.

The thirteen fish and goat are reported from the cave. QbitAI, the official account, holds your hand. Although I can't see your soul, my brain waves are quietly in sync with you.this is not the nonsense of the godstick, but the conclusion proved by scientific experiments.a study from the University of Haifa in Israel has shown that physical contact with a close person can synchronize people's brain waves.and the closer the relationship is, the more obvious the magical effect will be.sounds a little weird? Think of the mantis woman in the Galactic guard who can attack the soul? Mantis, the Galactic guard, but the data don't lie. Professor Simone shamay tsoory of the research team said: This study shows for the first time that the brain waves of both sides are synchronized during the handshake.it seems that even scientific evidence is telling you that if you express your love with your body, you may understand the TA better.holding hands tightly, the researchers set up an electroencephalogram (EEG) experiment.they invited 22 heterosexual couples, aged between 23 and 32, who had no children and maintained a long-term relationship.in the experiment, a female subject would receive pain stimulation under five different conditions, while her male partner would consider whether there was physical contact: touch + pain (no touch pain) touch + no pain (no touch no pain) no pain (no pain), no pain (no pain), no pain (no pain) (baseline condition) △ the upper part is female and the lower part is male.the EEG signals of the two were collected synchronously.the experiment was divided into three stages.the first stage is behavior analysis. The empathy accuracy under touch + pain is higher than that without touch + pain, which indicates that the touch of partner increases the accuracy of empathy.under the condition of touch + pain, the score of female subjects on the degree of pain was lower than that under the condition of no touch + pain and only pain stimulation, which confirmed the analgesic effect of touch.the second stage is the analysis of brain connectivity.in the figure, "target" is the female partner (pain target), "Observer" is the male partner (touching person), the orange line represents the statistically significant brain connection, and the color on the scalp represents the number of connections in this area.it is not difficult to see that there is a certain coupling relationship between the two brain regions under certain conditions.figure a: in the condition of no touch and no pain, the brain connections were mainly concentrated in the female right parietal regions and the male parieto occipito temporalares; figure B: under the condition of touch + no pain, the main sets of brain connections were in the female central regions and the male fronto central regions Figure C: in the condition of no touch and pain, the brain connections were mainly concentrated in the right front regions, left central front areas in women and left central front regions in men. but in Figure D, it is very obvious that the number of brain connections under the condition of touch + pain is the most, which is 22. mainly concentrated in the left and right central frontal regions of women and the right frontal parietal occipital regions of male subjects. it is not difficult to see that the coupling relationship between the two sides is the most close under the condition of touch + pain. this shows that the brain waves of the two sides holding hands are synchronized. the third stage is the clustering analysis of brain connections. This step mainly uses the NMF (statistical analysis) method to cluster the brain connections under the conditions of touch + pain and no touch + pain. in both cases, the three cluster solution fits best. then, the researchers studied the relationship between behavioral data and brain connectivity. the results showed that cluster 2 was significantly associated with analgesia under the condition of touch + pain. however, there was no significant correlation between cluster and analgesia under the condition of no touch + pain. that is to say, the pain is relieved when the EEG is synchronized after holding hands. brain wave synchronization can relieve pain. What kind of experience did the subjects have? In a similar set of experiments, each female participant was tested under four different experimental conditions: the pain baseline test (partner in the next room): thermal stimulation with a pain intensity of 60 for 75 seconds. pain test without contact with partner (partner at the side): pain stimulation is the same as the previous item. pain test in contact with partner (handshake): no change in pain stimulation. pain test in contact with strange opposite sex (handshake): the pain stimulus was unchanged, and the stranger was acted by male researchers. keep 10 minutes of rest between each test to avoid affecting the experimental results. △ A: pain only; pnt: no contact with partner; PT: contact with partner; ST: contact with stranger. the results showed that when the subjects felt pain alone, the average pain level captured after 5 seconds of pain stimulation was 51.33. when contacting strangers, the average pain level of the subjects was 51.71. however, when the partner was in front of him but there was no physical contact, the average pain level dropped to 34.12. when holding hands with a partner, the pain level dropped to 23.14. that is to say, when shaking hands with a partner, people's physical pain really decreases. but contact with strangers doesn't help. It's almost like being alone. moreover, the more your partner sympathizes with your pain when you and your partner hold hands, the more your pain will be relieved. △ in contact and non-contact state, the relationship between partner empathy and the pain level of subjects is the same-sex "true love"? It is worth noting that the relationship between subjects plays a key role in the experiment. here comes the interesting results. this kind of interpersonal coupling relationship is still obvious when two strange same-sex subjects do the experiment. however, this coupling relationship will be weakened in two strange heterosexual subjects. the coupling relationship between couples is more obvious than that of only friends or strangers. What's more, if the positions of men and women are mutually adjusted, that is to say, boys are painful targets and girls are tacticians, the strength of this coupling relationship will also change. it seems that boys and girls do play different roles in the process of cooperation. unfortunately, the study did not focus on same-sex couples. one more thing since touch and empathy have synergistic analgesic effects, it may have important significance for acute pain. for example, delivery. in fact, it has been reported recently that in 60% of cases, the presence of a partner during childbirth is effective, and the presence of the father plays a positive role in all aspects of the delivery process. when a girl is visited by "relatives" every month, is there a new way for boys to relieve her pain besides preparing hot water? Anyway, don't be shy. after all, now that science supports you, it's good to have more physical contact with close people. portal paper link: - end - the gathering of the big names!
