Shorter, more frequent touches are better than longer, rarer ones

Parents and romantic partners naturally touch at speeds optimizing nerve activation

A small observational research study shows that when parents are asked to caress their infants and volunteers are asked to caress their partners, both groups spontaneously stroke their loved ones at velocities that, on average, fell within the optimal range to stimulate the C-tactile afferent nerve receptors. This wasn't the case when volunteers were asked to do the same with an artificial arm, which they stroked much faster.

73% of people report they crave more physical touch in their lives

This figure came from a 2019 survey of 110 adults and examined what's formally called a "touch gap." Touch helps reduce stress, strengthening our immune system, and overall well-being. It can also improve children's health, adjustment, and IQ scores.

Touch helps newborns regulate stress, gain weight, and feel less pain

Conclusions from this 2024 analysis from a team of Danish researchers included that touch interventions were particularly useful for newborns in regulating cortisol levels, helping newborns gain weight, and reducing pain. (Some users may experience a paywall.)

Generally, NBA basketball teams whose players touch each other more win more games

This 2010 research finding underscores the importance of touch in promoting trust, bonding, and cooperation, thereby apparently improving team success. Touch also promotes cooperation in other settings: In a separate "prisoner's dilemma" study, when the experimenter gently touched some participants with a quick pat on the back, the touched individuals were more likely to cooperate and share with their partner.

Blindfolded people could identify objects by touch alone a week after encountering them

These touch memories are more complex and durable than previously thought. In research published in 2018, blindfolded volunteers touched over 150 household objects for about 10 seconds each, and afterward correctly identified the objects more than 90 percent of the time when presented with the object and a similar one. Participants still knew most of the objects a week later with about 85 percent accuracy. (Some users may experience a paywall.)

A researcher thinks she knows why people keep touching museum exhibits

A museologist who studied unauthorized touch at the British Museum concluded that people may feel it's difficult to learn about things "unless you handle them" and that people are trying to connect with the past, viscerally. Her work has included interviewing British Museum visitors who committed unauthorized touches and spending extensive periods observing people touching prohibited items across 2004 and 2005.

We can sense touch even through a tool

Research published in 2019 indicates that the same brain regions involved in sensing touch on the body also process it when humans use a tool to do the touching. Essentially, it's acting as a sensory extension of the body. (Some users may experience a paywall.)

Touch is the first sense a fetus develops in the womb

During gestation, our sense of touch begins to develop around 8 weeks, starting with the development of sensory receptors in the face and, about a month later, in the palms and soles of the feet.

Baby monkeys chose a soft, warm doll over a wire one with food

Harry Harlow performed controversial experiments with newborn monkeys, separating them from their mothers and letting them bond with stand-in mother figures made from either wire or figures covered in cloth—both with monkey-like faces. The work investigated touch, bonding, and attachment, and found that monkeys overwhelmingly preferred the cloth dolls over the wire ones in various stressful situations.

Consistency and emotional engagement can improve the formation of memories

While sleep lets the brain re-trigger neurons associated with our experiences to cement them in long-term memory, repeating actions, like storing one's keys in the same location, can mimic these benefits. Emotionally charged memories are often ruminated upon, improving their future recall.

Genetics may account for nearly 67% of mosquito attractiveness

In a mosquito attraction study published in 2015, identical twins appeared equally attractive to mosquitoes in lab tests, whereas some nonidentical twins were far less likely to be bitten than their siblings. Other work related showed that body odor is also more similar between identical twins.

Who provides therapy is more important than what method they practice

What makes therapy work well is the connection that patients feel with their therapist, and the trust in that relationship. Some research suggests that while the therapeutic model—say cognitive behavior therapy or psychodynamic therapy—accounts for roughly 15% of outcomes, the therapeutic relationship with the therapist accounts for more than 30%.

Electromagnetic repulsion prevents objects from making contact with one another

The feeling of touching something is a sensation caused by the electromagnetic force between the electrons on the surface of objects. Since this force grows to infinity with proximity, no two surfaces can ever achieve matter-to-matter contact.

How texture affects taste

Texture is the brain's interpretation of several sensations, including pressure, as registered by our teeth, tongue, and finger tips, and sound, as recorded by our ears. Texture also speaks to food particle sizes—smaller than 35 microns contributes to the sensation of creamy—and the balance between flavor and mouth time, such as the crunch of a crispy chip or the bounce of a chewy caramel.

Studies suggest when you sleep is as important as how much you get, and syncing with your circadian rhythms may lead to less fatigue and improved long-term health outcomes

Helping support others in older age linked to longer life

Analysis of findings from a long-term study of older couples first interviewed in 1987 and then followed for the next five years found that individuals who lend support to friends, neighbors, and relatives live longer. Non-helpers were more than twice as likely to die as helpers during the five-year period. That's even after controlling for factors including age, gender, and physical and mental health.

Are we too attached to attachment styles?

Attachment theory was developed to help understand the impact of caregiver relationships on children. Recently, the theory has been applied to adults, categorizing them into different attachment styles. Is it accurate? This podcasts takes a closer...

Sleep is often viewed individually, when its impact and meaning may be more communal

At any given point, roughly 2 billion people may be asleep on Earth. The typical scientific description of sleep focuses on its individual impact, but the phenomenon shapes whole cultures and eons. This essay prompts a fresh rethinking of the importance of sleep for humanity.

The exercise sweet spot is shorter than you'd think—and longer workouts aren't generally better

A meta-analysis concluded that resistance training for about 60 minutes per week provided the best health benefit—decreasing the likelihood of death for individuals within a specific timeframe around 27%.

How the buildings you occupy may affect your brain health

Beautiful spaces filled with light and natural motifs aren't just aesthetic, but likely key to your health. Researchers had study participants view photographs of two distinct buildings, one designed with more natural elements while the other featured more abstract shapes and lines. Using electroencephalograph readings of each participant, they discovered participants had less brain inflammation while viewing the "biophilic," or natural, architecture. Learn more about the interdisciplinary framework of so-called neuroarchitecture here.

The most common types of touchscreens are capacitive and resistive

Capacitative screens are coated with a conductive material that creates a uniform electric field, which is disrupted by fingers. This disruption is registered by the device across a grid to determine where contact was made. Resistive screens identify touch when fingers push gap-separated sheets into contact with one another.

Eliminating distractions is essential to improving one's attention span

Setting a baseline, removing distractions, establishing focus rituals, taking breaks, and finding purpose in your task are five science-backed practices that can help address a short attention span. Bestselling author Daniel Pink breaks down how to approach each part of the plan and introduce these habits to your life today.

Is using VR as a tool to enhance empathy ethical?

This research paper explores whether virtual reality should be used as a tool for improving our moral character — and, if not, what ethical alternatives could be.

Humanity's reduced body hair slows down wound healing

Cuts to human skin take twice as long to heal compared to chimps and other mammals. Scientists argue this is due to the reduced number of hair follicles on human bodies. Hair follicles contain stem cells which help repair skin cells faster, so as humanity shed its hair over time, so to speak, it also slowed its wound healing.

Recent research found that the brain doesn't seem to massively rewire following amputation—upending earlier beliefs about the cause of phantom limb pain.
