What does research say about physical affection between partners?

What counts as affectionate touch in this research

In these studies, affectionate touch means physical contact meant to show care that isn't sexual: hugging, holding hands, an arm around a shoulder, a back rub, sitting pressed together on a couch, a kiss hello. Researchers usually separate it from sexual touch and from functional contact like handing over a mug.

For a long time this kind of touch was studied mainly in infants, where its importance is well established. In 2017 the psychologists Jakubiak and Feeney reviewed the adult research and found that the effects of touch in adult close relationships had been largely unexplored (Jakubiak and Feeney, 2017). Their review proposed a model that much of the later work set out to test, so it is a useful map of what follows.

Two routes from a hug to feeling better

The 2017 model describes two kinds of immediate change when someone receives affectionate touch from a partner (Jakubiak and Feeney, 2017):

• A change in how you think about the relationship. Touch may signal that your partner is available and on your side, which can raise your sense of security and make you feel more like part of a pair.
• A change in the body. Touch may dampen the body's stress response, through hormones and the nervous system.

Those changes, the model proposes, can improve well-being in two ways: by softening the impact of stress when something hard is happening, and by adding to well-being on ordinary days when nothing is wrong. It's a theory, and the authors presented it as an agenda for research rather than a settled account. The studies below each test a piece of it.

Experiments that assigned couples to touch

Correlational studies can't tell whether touch helps or whether happy couples just touch more. Experiments get closer by deciding at random who gets touched.

Two patterns stand out. First, physical contact did something that words did not, at least in the massage study, where women whose partners talked supportively showed stress responses no lower than women left alone (Ditzen and colleagues, 2007). Second, the effects show up both in bodies (cortisol, heart rate, blood pressure) and in behavior (how couples argued), which fits the two routes the review described.

A hand you trust works better

One of the most cited touch studies is small but striking. Sixteen married women lay in a brain scanner and faced the threat of a mild electric shock while holding their husband's hand, a stranger's hand, or no hand (Coan and colleagues, 2006). Holding the husband's hand reduced activity in brain systems tied to threat; a stranger's hand helped less. The calming effect of the husband's hand was larger in higher-quality marriages.

Sixteen women is a tiny sample, and fear of a shock is far from a Tuesday night argument. But the direction of the finding is worth noticing: touch is not a neutral input that soothes regardless of who supplies it. The relationship carries into the touch.

Does touch help unhappy couples?

Most touch research has used couples who are fairly satisfied, often college students. Jakubiak set out to address that with two nationally representative samples (Jakubiak, 2022). In the first, people who kissed their partner more often reported greater well-being, and the link was strongest in the most satisfying relationships. In the second, people were randomly assigned to imagine receiving affectionate touch from their spouse, or not. Those who imagined touch expected less stress, more life satisfaction, and more security and closeness with their spouse. The benefits were larger when the relationship was moderately or highly satisfying, but they still appeared among the roughly one third of participants who rated their relationship as distressed.

The second study measured what people expected touch would do for them, not what real touch did. Even so, together with the hand-holding brain study above, it points to a sensible middle position: touch probably isn't wasted in a struggling relationship, but it does the most where there is already goodwill to amplify.

When touch isn't welcome

People differ in how much touch they want, and that difference runs through the research. In two studies of people in dating, engaged and married relationships, women and people in higher-quality relationships wanted more touch, while people higher in attachment avoidance wanted less (Jakubiak and colleagues, 2021).

Does touch still do anything for the people who want less? Anik Debrot and colleagues tested this directly across three preregistered studies with self-reports, lab observation and daily diaries (Debrot and colleagues, 2021). Avoidant people touched less and reported lower well-being, but touch went with better well-being at every level of avoidance, and less touch partly explained the avoidant group's lower well-being. The authors framed this as a reason to take touch seriously even for people who value distance. The data are correlational, so they can't show that adding touch would raise well-being for avoidant people.

The reasons behind touch also matter. A separate pair of studies found that touching a partner to feel close went with better daily relationship well-being for both people, while touching mainly to avoid something unpleasant, such as a partner's disappointment, went with worse (Jakubiak and colleagues, 2021). A hug given grudgingly may not carry the benefits in the table above. The page on a partner who isn't affectionate turns this into practical steps for couples with different appetites for touch.

The widest lens: touch interventions across 137 studies

A 2024 meta-analysis in Nature Human Behaviour pooled 137 studies of touch interventions, with 75 more in its systematic review and 12,966 people in total (Packheiser and colleagues, 2024). Every included study compared touch with a no-touch condition. For adults, touch reduced pain, depressive feelings and anxiety by moderate amounts (for depressive feelings, a standardized effect of about 0.59; for momentary anxiety, about 0.64). Adults in clinical groups benefited more on mental health than healthy adults. Touch from a familiar person, such as a partner or friend, helped adults about as much as touch from a health professional.

The caution is in what was studied. These were deliberate interventions, many given by health professionals or to clinical groups, not the passing hugs and hand-holding of daily couple life. The authors also flagged some small-study bias, and nobody can be blinded to whether they are being touched. So the meta-analysis supports touch as a reliable mild help with stress and mood. It doesn't tell you how many hugs a day a relationship needs, and we found no study that does.

What the research cannot tell you yet

• Long-term effects. The longest experiment above ran four weeks. Nobody has randomly assigned couples to touch more and followed them for years.
• Who was studied. Samples skew young, Western and heterosexual, often students, and several key studies included women only. Same-sex couples, older couples and many cultures are barely represented.
• Real versus imagined touch. Several studies, including two of the conflict experiments and the large representative experiment, asked people to imagine touch. Imagined effects may be larger or smaller than real ones.
• Sample sizes. Many of the experiments had a few dozen couples. Results from studies that small can shrink when repeated.
• Popular numbers. Claims about an exact number of daily hugs or seconds per hug did not appear in any study we reviewed for this page.

Using the evidence without overselling it

Touch between partners who both want it is one of the cheapest things a couple can do that has experimental support behind it. It is not a repair for contempt, betrayal or a partner who feels unheard, and the research above suggests it works best when the relationship already has some warmth to build on.

A few practical readings of the studies:

1. Before a hard day, not only after. In the massage study the touch came before the stressor. A hand on the shoulder before your partner's difficult meeting may help more than a hug at the end.
2. During a disagreement, if you both agree. Sitting close or holding hands while you talk through a calm disagreement is what the conflict experiment tested. Agree on it beforehand; a hand grabbed mid-argument is a different situation, covered on the page about wanting a hug after a fight.
3. Ask rather than assume. People differ widely, and touch given to avoid trouble seems to lose its benefit. Asking for more affection has wording for that request.
