A hug is universal. Hugs are so versatile, people all around the world use them to express everything from joy and affection to sadness and despair.
During times of social, emotional and mental turmoil, individuals seek out the comfort and social bonding that hugs bestow.
Some people even believe a hug is at the heart of humanity since it has the ability to transcend race, religion, gender and age. In fact, being a professional hugger and/or cuddler is a legitimate job.
Professional huggers and cuddlers provide hug benefits to people during all different points of their lives. For instance, some specialize in using this touch therapy on premature babies in neonatal intensive care units.
Other hug and cuddle professionals focus on nursing home or hospice situations, while others are available for hire by anyone in need of human touch.
Similarly, Ken Nwadike Jr., a peace activist and founder of the Free Hugs Project, attends rallies and protests to spread love and compassion. During the 2016 protests in Charlotte, Nwadike wore a “free hugs” T-shirt and was captured sharing hugs during a time of riots, protesting and intense emotion.
How to Hug During a Pandemic
During a pandemic, keeping social distance is important. We also know about the importance of human connection, so if you’re going to hug a loved one, there are ways you can do it more safely.
For starters, both huggers should wear masks. During your embrace, put your faces in opposite directions in order to reduce the risk of exposure.
For children, hugging an adult around the waist is safer. You should also keep your hugs brief during a pandemic.
It’s also helpful to wash hands after hugging and avoid making contact with someone’s skin.
Although the idea of changing up your hugging may seem strange, it’s best to make these little adjustments right now so we can continue occasional close contact with loved ones while keeping them safe.
How Many Hugs a Day Does a Person Need?
How many hugs a day does a person need? Although not technically proven by science, the late psychotherapist Virginia Satir once said:
“We need four hugs a day for survival. We need eight hugs a day for maintenance. We need 12 hugs a day for growth.”
Although these numbers aren’t an exact science, it suggests that we could probably all stand to give (and receive) more hugs every day. There is a pretty large body of research proving the importance of hugs and physical contact.
It’s not only the amount of hugs you give or receive in a day, but the amount of time that the hug lasts that’s important. While the average length of a hug is about three seconds, some researchers suggest that longer hugs, lasting 20 seconds or more, are even more therapeutic for the body and mind.
The science behind a longer hug being better comes from the oxytocin release that occurs during an extended hug. This “love hormone” is able to calm our anxiety and ease our fears.
Benefits of Hugs
In order to understand the benefits of hugs, we have to first take a look at the sensory pathway involved.
When an individual is hugged, the sensory receptors in the skin are activated. There are several sensory receptors within the skin, and they respond to touch or distortion on the skin.
Along with the sensory receptors, there are also sensory nerves that innervate the skin and respond to touch.
One group in particular, the C-tactile afferents, play a major role in the effects of hugging and touch. Research shows that C-tactile afferents are found in hairy skin and respond optimally to a low-intensity, stroking touch, and they have been shown to fire most strongly to what people perceive as pleasant touch.
These sensory nerves also play a prominent role in the touch hypothesis. This hypothesis states that the sensory nerves are developed to signal the rewarding value of physical contact.
Once activated, the sensory receptors and nerves transduce the mechanical stimulation into electrical and chemical signals that travel along the peripheral nerve to the spinal cord and continue onto the opposite side of the brain.
Sensory pathways activate brain regions associated with:
- Social bonding
Now that we’ve got a little pathway education under our belts, let’s take a look at the fun part: hug benefits.
1. Vital for Healthy Childhood Development
Ever wonder what a hug does? Turns out, hugs/human contact are a vital first part of life.
Interaction through touch is so crucial to the human experience, especially to a child’s well-being. The sense of touch is widely believed to be the first of the senses that develops in utero.
Immediately following the birth and the early stages of life, physical contact (skin-to-skin) between the mother/caregiver and the infant is crucial for child development.
That’s why whether you’re having a natural childbirth or C-section, getting that mother-to-child, skin-to-skin contact as soon as possible is so very important.
The touch of the mother enhances feelings of attachment, security and positive emotions. A 2010 study showed that babies with affectionate mothers grew up to be happy, resilient, less stressed and less anxious adults.
Studies using EEG to measure brain activity have shown cuddling increases brain responses when infants are presented with displays of affection from parents, which may cause lasting effects on the way the brain builds connections. These interactions and new-forming brain connections enable children to learn how to manage stressful situations on their own and how to manage their emotions appropriately.
On the other hand, children with little affection or skin-to-skin contact following birth have been shown to have cognitive, emotional and physical issues, as well as have an increase in cortisol levels. (Cortisol is the hormone commonly associated with stress.)
In 2015, a study done at Notre Dame found that children experiencing just a small amount of touching and hugging in early infancy grew up to have worse health and more emotional problems compared to kids experiencing more hugs. This illustrates the damaging effects of a lack of affection.
2. Boosts Oxytocin
Following activation of the C-tactile afferents, the “love” hormone, oxytocin, is released from the neurons projecting from the hypothalamus, the region of the brain that is part of the limbic system or reward system. It is responsible for regulation of many of the metabolic processes of the autonomic nervous system.
Oxytocin is made within the hypothalamus and is largely known for its effects on social bonding. Studies indicate that neurons that produce oxytocin project widely throughout the brain, including into regulatory regions associated with social interaction, fear, aggression, calm and stress.
While much of the oxytocin that is released acts on various structures that have an impact outside of the brain, some of the oxytocin remains within the brain and influences behavior, mood and physiology by acting on the limbic (emotion) center, stimulating the feeling of contentment, decreasing anxiety/stress and increasing social bonding.
3. Provides Immune System Support
The increase of oxytocin also helps the effectiveness of the immune system. Yes, that’s right: Hugging can be considered a natural immune system booster.
Hugging induces the “stress buffering effect” in which an individual who is hugged often is less likely to become sick due to stress-induced illness.
Oxytocin acts on the pituitary gland to decrease the stress hormone cortisol. Along with a decrease in cortisol, the social support through physical contact also allows an individual to cope with stressful situations, rather than wearing down the immune system and leaving room for illness.
A study in 2015 at Carnegie Mellon exposed healthy adults to the cold virus and found that individuals with social support had a decreased chance of getting sick due to the stress-induced buffering effects of hugging. The results concluded that those individuals who did get sick had less severe symptoms if they were hugged and had a stable social support than those that did not.
Simultaneously, as the activated sensory receptors send signals to the brain, signals are also sent to the vagus nerve. The vagus nerve is the cranial nerve that helps mediate the parasympathetic response of the heart, lungs and digestive tract.
This decreases the blood pressure, helping both individuals involved in the hug feel calmer. In animal studies, activation of the vagus nerve has also been shown to increase the release of oxytocin, decreasing the heart rate and cortisol, leaving the person feeling less stressed and more relaxed.
4. Produces “Chill Out” Neurotransmitters
Several neurotransmitters are increased in the brain following the activation of the sensory neurons that play a role in the positive emotions associated with being touched. The neurotransmitter dopamine is associated with motivation, goals and reinforcing behavior.
Research shows that hugging releases dopamine within the limbic pathway in the brain, creating feelings of pleasure and satisfaction.
It is through the increased release of oxytocin, in conjunction with the neurotransmitters, that creates the soothing and calming feelings one experiences following a hug.
5. Boosts Self-Esteem
Hugging and human contact are critical for infants, children and adults. There are also associations of self-worth and tactile sensations that are established when we are babies, which have a lasting impact on our nervous system.
Who knew that hugs have a major impact, even at a cellular level?
Research shows that hugging is an effective means of conveying social support, which we know is so important for our self-esteem and sense of self-worth.
- The simple act of human touch, including a hug, causes a cascade of events, beginning with the sensation of a touch on the skin traveling along nerves to the brain, causing changes that affect the entire body.
- Sensory receptors and nerves work together sending signals to the central nervous system to provide enough information for the individual to create an appropriate motor and emotional response.
- This allows an individual to engage with the environment through the neuronal processing of a touch stimulus, which leads to eliciting a response that is often emotional in nature.
- Hugging increases oxytocin and other neurotransmitters associated with happiness and pleasure, while decreasing stress hormones, blood pressure and heart rate.
- The overall general effects of hugging lead to an increase in social bonding, relaxation and a decrease in stress — and therefore result in a better quality of life.
