20 Amazing Benefits Of Hugging According To Science

Over the centuries, various forms of interpersonal touch have become less common, influenced by changes in cultural values and new technology.

Nowadays, with twenty four hour access to mobiles, texting and email, many people spend more time interacting with their technology than they do with each other. This lack of touch has many effects on different aspects of our lives, and can lead to feelings of loneliness, isolation and insecurity.

So why is touch so important to us? We typically think of touch as a pleasant, but not very important part of life. But touch plays an integral role in our daily experiences. It influences what we buy, what we eat, who we love, and even how we heal. We use our sense of touch to gather information about our environment and to establish social bonds with each other.

Multiple studies have concluded that touch, especially hugging, provides numerous health benefits. If you’re looking for a great way to boost your immune system, reduce your stress, improve your sleep and even help cure depression, you need to consider hugging. Hugs have no side effects and require no prescription. Even better, they’re free and can be given and received anywhere, at any time.

Here are 20 great reasons why you should hug and allow yourself to be hugged every single day.

1. Hugging Helps to Fight Stress Induced Illness

It’s a well known fact that stress can weaken the immune system, leading to colds and other illnesses. As the body tries to cope with stressful situations, it responds by becoming physically sick.

Scientists have been investigating the link between physical touch and a healthy immune system. In a 2015 study involving 404 healthy adults, researchers from Carnegie Mellon University examined the effects of receiving hugs on the immune system. Participants were tested on their susceptibility to the common cold, after being exposed to the virus.

It turns out that the people who received more hugs, and greater social support, were less likely to get sick. In fact, researchers calculated that the stress-buffering effects of hugging explained thirty two percent of that beneficial effect. And amongst those participants that did get a cold, those that received hugs reported fewer symptoms.(1)

The researchers concluded that hugs are a way of providing support, and being hugged more frequently could be an effective means of reducing stress and stress related illness.(2)

Bottom line: Hugs help us fight stress and keep us healthier.

2. Hugging Boosts Our Immune System

Hugs strengthen the immune system. When you hug someone you are placing some gentle pressure on their sternum. This activates the Solar Plexus Chakra and stimulates the thymus gland. The thymus gland regulates and balances the body’s supply of white blood cells, keeping you healthy.(3)

The link between touch and a healthy immune system is also documented in a

2010 study published in the journal Developmental Review. The study examined the effects of massage therapy, and concluded that participants showed a noticeable drop in heart rate and blood pressure. They also exhibited a boost in their immune systems, increasing their white blood cell count and decreasing their levels of cortisol.(4)

Bottom line: Hugs boost the body’s immune system and keep us healthy.

3. Hugging Reduces Stress

When we are stressed our nerve endings send information to the body to release the hormone cortisol. This hormone slows down the body’s healing process. Cortisol stimulates the body’s ‘fight or flight’ response, which, if not controlled, creates a number of health problems.

Studies have shown that hugging can affect cortisol levels in the body by causing the release of a hormone, oxytocin, known as the ‘love hormone’. Oxytocin is also referred to as the hug hormone, cuddle chemical, moral molecule, and the bliss hormone due to its effects on behavior, including its role in love and in female reproduction.(5)

When we receive a hug, the body releases oxytocin, making us feel calmer and more relaxed, and stress levels are reduced. The oxytocin acts on the limbic system, the brain’s emotional centre, promoting feelings of contentment, reducing anxiety and helping women endure the pain of childbirth. Matt Hertenstein, a psychologist at DePauw University describes oxytocin as promoting feelings of devotion, trust and bonding, and says it lays the biological foundation and structure for connecting to other people.(6)

Bottom line: Hugs reduce stress by releasing oxytocin which relieves anxiety and helps us to bond.

4. Hugging Satisfies Our ‘Skin Hunger’

Skin is the body’s largest organ. It acts as a defence against the outside world, regenerating at an incredible rate Skin is also our brain’s data collector. The soles of our feet, the tips of our fingers, and our lips are all especially designed to collect the smallest details of sensory data and transmit them to the brain via nerve endings.(7)

Touch is the very first sense that we acquire, so it makes sense that touch and physical contact is necessary for our well being.

Sadly, many people are touch-deprived. One study found that one-third of people receive no hugs on a daily basis while 75 percent said they wanted more hugs.(8)

Humans become nearly unrecognizable in the absence of touch. Two hundred years ago, French scientists spotted a creature resembling a human running through the forests. Eventually the creature was caught, and it turned out to be an 11 year old boy. They named the child Victor, and determined that he had been living wild in the forest for most of his life. Initially doctors thought that Victor was mentally retarded, but eventually the physicians and psychiatrists concluded that he had been deprived of human physical touch, which had retarded his social and developmental capacities.(9)

These findings are validated in a study conducted by the Miami Touch Research Institute, which demonstrated the importance of touch for preterm babies. Babies that received daily massages has an accelerated growth rate forty seven percent greater than the babies in the control group, who were not given massages.(10)

Bottom line: Hugs provide the skin contact that our bodies need to remain healthy.

5. Hugging Increases Serotonin Levels

Serotonin is a neurotransmitter which is produced and spread by neurons in the brain. It is formed by the amino acid called tryptophan, which sends messages through the blood and tells the brain to produce serotonin.

Serotonin is known as the ‘feel good’ hormone because it helps to make us feel happy, relaxed and confident. It also acts as an appetite controller, and mood regulator.(11)

Health issues such as depression and obesity have been linked to an imbalance in serotonin levels. Serotonin affects and controls mental and emotional processes, motor functions, hormones, blood pressure and motor functions.

Low levels of this hormone can cause sleep disorders and even obesity, as most of our serotonin is found in the body’s digestive system. When levels of serotonin are too low, the brain receives a signal that the body is hungry, and we feel the urge to eat. Studies have shown that there is a direct link between obesity caused by overeating and low levels of serotonin.(12) Once serotonin levels normalise, the desire to keep eating disappears.

Serotonin flows when we feel important or significant, and the reverse is true when serotonin is absent. We feel lonely and depressed. This can lead to unhealthy attention seeking behaviour, or even cause people to join gangs and fall into criminal behaviour.(13)

Many antidepressants on the market today are based on increasing the production of serotonin. However, there is an easier and healthier way; hugging. Hugging releases serotonin into the body, which improves our mood and helps to increase our happiness.(14) High levels of serotonin negate sadness and increase pleasure. This has an immediate effect on our mood and how we feel.

Bottom line: Hugging increases serotonin levels in the body, making us happier.

6. Hugging Balances the Nervous System

When we receive a hug, a network of tiny, egg-shaped pressure sensors called the pacinian corpuscles send messages to the brain via the Vagus nerve. These corpuscles can sense touch and react to it.

Studies have shown that when a person receives a hug, their galvanic response shows a noticeable difference in skin conductance. This is due to a transfer of electricity and moisture from the person doing the hugging. These electricity and moisture levels create a more balanced nervous system.(15)

According to neurologist Shekar Raman, MD, forms of touch such as a hug or pat on the back are processed by the reward centre in the central nervous system, making us feel happiness and joy.(16) The more we connect with others, the happier we feel.

Bottom line: Hugging leads to a balanced nervous system.

7. Hugs Are Anti-Aging

As we age, our hormone levels drop, leading to a loss of muscle mass. In fact, our bodies lose up to five percent of our muscle mass each decade past our thirties.(17)

Now studies are focusing on the benefits of oxytocin in regenerating muscle mass and activating muscle signal pathways.

In a study conducted on mice, in which researchers injected oxytocin into older mice with muscle damage, they exhibited better healing after nine days than mice who did not receive the hormone. The mice that received oxytocin were able to repair muscle damage up to eighty percent more than the young, untreated mice.(18)

The results demonstrated that oxytocin is important in maintaining a youthful body and healthy muscles. Since hugging increases the body’s capacity to release oxytocin, it also has the capability to help prevent aging.

Bottom line: Hugging keeps us young and maintains muscle strength.

8. Hugging Protects Against Heart Disease

Scientists have shown that hugging causes the body to produce oxytocin, helping to calm the nervous system and create relaxation, but oxytocin has another as well. It reduces blood pressure and heart stress.

In a study conducted by the University of North Carolina, Chapel Hill, researchers worked with two groups of women. The first held hands with their partners for ten minutes then hugged them, while the second group just sat quietly next to their partners. After the ten minutes were up, the women discussed a recent event that had been stressful for them. The women in the no-contact group showed significantly higher blood pressure readings than those who hugged and held hands.(19)

The participants who did not have any contact with their partners also developed a quickened heart rate of ten beats per minute compared to five beats per minute among those who got to hug their partners during the experiment.(20)

Bottom line: Hugging leads to lower blood pressure and a reduced heart rate.

8. Hugs Act as Nonverbal Communication

Almost seventy percent of communication is nonverbal. The interpretation of body language can be based on a single gesture and hugging is an excellent method of expressing yourself nonverbally to another human being or animal.

Judith Kestenberg, a psychoanalyst specializing in child development, has conducted research on muscle tension. Her study shows that all muscles exhibit an ever-changing alternation in muscle tension during any activity.

Based on her observations of babies, Kestenberg identified ten rhythmic patterns changes that she felt corresponded to particular developmental tasks. Each rhythm has its own specific meaning and non-verbal signal. For example, one type of rhythm indicated a withdrawal or separation between two bodies, while another rhythm simulates the need for bonding and connectedness.(21)

In a well documented case, twin babies born twelve weeks prematurely were placed in an incubator together. This allowed skin to skin contact and stabilised the weaker baby. This practice has come to be known as ‘kangaroo care’, and is often used to help premature infants regulate their temperature, gain more weight, and sleep better.(22)

Kangaroo care is not a new phenomenon. In the early 1980s, the mortality rate for premature infants in Bogota, Colombia was seventy percent. The babies were dying of infections and respiratory problems as well as lack of attention paid to them by a bonded parent.

‘Kangaroo care’ for these infants evolved out of necessity. Mothers were given their babies to hold twenty four hours a day, keeping the baby tucked under their clothing as if in a kangaroo’s pouch. If a baby needed oxygen, it was administered under an oxygen hood placed on the mother’s chest.

When doctors studied the health of these babies, they noticed a drop in neonatal deaths. Babies were not only surviving, they were thriving. Currently in Bogota, babies who are born as early as ten weeks before their due date are allowed to go home within twenty four hours, as long as they can breathe on their own, are able to suck and have a healthy colour.(23)

Bottom line: Hugging is an important form of nonverbal communication and provides multiple health benefits.

9. Hugging Relieves Pain

Sales of over the counter pain medications have exploded in recent years, even though in many cases their effectiveness is limited.

Now scientists have found that emotional bonds can reduce pain aches and pains. They call this effect ‘love induced analgesia’.

Researchers at Israel’s Haifa University recruited dozens of female volunteers and repeatedly subjected them to temporary, mild pain by touching them with a hot metal rod. In the first experiment, a complete stranger held the women’s hands to try to comfort them, while in the second experiment they had a partner standing near them but not touching them. In the final experiment the partner was allowed to hold and stroke the woman’s hand as she was being touched by the hot metal.

The results showed that when a loved one touched their skin, volunteers’ pain scored dropped significantly. The researchers also found that the more a woman’s partner expressed empathy and support during the experiment, the lower the level of pain and the greater the level of relief. The study concluded that social touch has a powerful pain killing effect and suggests that empathy between romantic partners may explain the powerful effects.(24)

Bottom line: Hugs from loved ones provide drug free pain relief.

10. Hugs Can Help with Depression

In addition to releasing oxytocin, hugging also causes the body to produce dopamine. Known as the pleasure hormone, dopamine is a neurotransmitter that helps control the brain‘s reward and pleasure centers. Dopamine also helps regulate movement and emotional responses. It allows us to see rewards and pushes us to take action to achieve them. Dopamine deficiency results in Parkinson’s Disease, and people with low dopamine activity may be more prone to addiction.(25)

Deficient levels of dopamine activity in the brain can cause depression characterised by low energy, and lack of motivation. In some cases, a severely dopamine deficient person may even wish to commit suicide, but often won’t do anything about it.(26)

Using MRIs and PET scans, scientists have shown that hugging stimulates the release of dopamine.(27) This is a much safer way of alleviating some of the symptoms of depression, than taking medications with multiple side effects.

Bottom line: Hugging raises our level of dopamine and reduces symptoms of depression.
