Research (Field, 2010) suggests that the severity of borderline personality disorder (BPD) symptoms and human touch are negatively correlated. In other words, those suffering from severe symptoms of BPD experience less physical contact with other human beings than do ‘BPD sufferers with less severe symptoms (all else being equal). This finding provides further evidence in favor of the many benefits, both mental and physical, of the experience of human touch and the deprivation of human touch can be severely detrimental to a person’s psychological and emotional welfare, as we shall see below.
First, let’s look at the benefits of human touch:
- Reduces anxiety and stress
- Improves immune system
- Lowers risk of heart disease
- Reduces blood pressure
- Reduces heart rate
- Increases levels of oxytocin
- Increases levels of serotonin
- Increases levels of serotonin
- Signals safety and trust
- Reduces pain
- Activates the body’s vagus nerve which is involved with our compassion response. (Read more about the vagus nerve here).
Now let’s look at the potentially detrimental effect of being deprived of touch:
Highly Controversial Study Involving Monkeys And What We Might Infer From Such Studies:
This famous (or notorious) study was carried out by Harlow (and its controversial nature acted as a catalyst for the emergence of the animal rights movement). The study involved keeping infant monkeys in isolation chambers for up to 2 years so that they were deprived of touch. These monkeys became extremely disturbed. An earlier experiment by Harlow had already established the importance of touch to these monkeys as it was found that when given the choice between clinging to
- A surrogate ‘mother’ made of wire and holding a bottle of food
2. A surrogate ‘mother’ made from soft cloth (like a cuddly toy) and NOT holding a bottle of food
the monkeys preferred number 2, suggesting that they prioritized the sense of comfort derived from the soft touch of the surrogate mother made of cloth to the easy access to food.
It is reasonable to extrapolate from this finding, given how closely related humans are to monkeys in evolutionary and genetic terms, that touch is equally indispensable to human welfare.
Some Examples Of Human Studies Showing The Benefits Of Touch:
– Research conducted by Field (of The Touch Research Institute at the University of Miami’s Miller School of Medicine) that involved HIV and breast cancer patients found that massage strengthens our immune system by increasing levels of our natural killer cells which kill viral and bacteria cells.
– Research conducted by the neuroscientist Edmund Ross found that touch stimulates the brain’s orbitofrontal cortex which is involved in feelings of compassion and reward.
– Research conducted by Feldman et al. (2013) involved 2 groups of premature babies There were 73 babies in each group):
GROUP ONE BABIES: Received skin-to-skin touch with their mothers
GROUP TWO BABIES: Received incubator care
Later, between the ages of 6 months and 10 years, all of the 146 individuals (i.e. the total of groups one and two) were given intermittent COGNITIVE TESTS.
It was found that, overall, individuals from GROUP ONE (skin-to-skin group) did significantly better than individuals from GROUP TWO (incubator group).
At AGE 10 YEARS individuals from GROUP ONE (skin-to-skin group):
- slept better
- contended better with stress
- had more advanced autonomic nervous systems
- had better cognitive control.
- pets (e.g. stroking a dog or cat regularly)
- massage therapy; research suggests it can ameliorate symptoms of depression and increase the effectiveness of the immunity system)
- tai chi
- weighted blankets (can provide the sensation of being held with beneficial physiological effects including calming the nervous system.
