Why Do We Shake Hands? The History and Meaning

What a handshake communicates

A handshake is a form of nonverbal communication: people convey a social message through a gesture rather than words. In many settings, it says, “I recognize you,” “It is good to meet you,” or “We are marking this moment together.” That makes it useful at introductions, reunions, farewells, celebrations, and business meetings.

The gesture can also signal a transition. A handshake may open a conversation, close a negotiation, congratulate someone, or acknowledge an agreement. It does not prove that two people trust each other or agree about everything. Rather, it follows a shared convention that can make an interaction feel orderly and respectful.

What a handshake means depends on the people and circumstances. A warm greeting between friends is different from a formal introduction between strangers. A brief, gentle handshake may communicate politeness; a prolonged or forceful one can feel uncomfortable. The gesture is only one part of the interaction, alongside words, facial expression, and the situation.

Where the custom came from

Handshaking is an old custom, but there is no single, universally accepted account of its origin. Ancient art and texts from different societies show people clasping hands, including scenes that may represent greeting, alliance, or agreement. These examples show that hand-to-hand gestures have had social meaning for a long time; they do not establish one simple origin story for the modern handshake.

A popular explanation says people once shook hands to show they carried no weapon. It is a plausible interpretation of what an open, visible hand might communicate, but it should not be treated as a proven explanation for how the custom began. Handshakes have appeared in varied settings and cultures, and their history likely reflects more than one practice or meaning.

Over time, handshaking became a conventional greeting in many European and North American settings and spread through diplomacy, trade, and other social contact. It is now common in many parts of the world, especially in formal and professional encounters, but it has never been the only way to greet someone.

Why hands became part of the greeting

Hands are visible, expressive, and useful for deliberate gestures. Extending one toward another person makes the act of greeting clear and creates a brief moment of mutual participation: both people choose to respond. The contact can make an encounter feel more personal than a nod or spoken greeting alone.

Some explanations emphasize the physical sensation of touch, while others focus on the handshake as a learned social signal. Both can matter, but there is no single effect that every handshake has on every person. People differ in comfort with touch, and the same gesture can feel friendly, formal, awkward, or unwelcome depending on context.

How handshakes vary

There is no single handshake used everywhere. Greeting customs vary by country, community, generation, religion, setting, and personal preference. Some people bow, nod, wave, place a hand over the heart, or exchange verbal greetings instead. Even in places where handshakes are common, not everyone expects one.

Expectations can also differ within one culture. A handshake may be routine at a job interview but unusual among close relatives. People may avoid physical contact for personal, religious, accessibility, or other reasons. When unsure, a simple spoken greeting and a pause give the other person room to signal what feels appropriate.

Handshakes are also not always between two people of the same gender. In some communities, norms around physical contact differ by gender, and extending a hand without considering those norms can cause discomfort. Following the other person’s lead is often more respectful than assuming everyone shares the same etiquette.

What makes a handshake respectful

In settings where a handshake is welcome, the aim is not to perform a test of strength. A respectful handshake is usually brief, comfortable, and responsive to the other person. Eye contact may accompany it in some settings, but expectations about eye contact also differ, so it should not be treated as a universal rule.

Offer, do not demand: Extend a hand naturally, but accept a wave, nod, or verbal greeting instead.
Keep the contact comfortable: Avoid squeezing hard, pulling, or holding on longer than the moment calls for.
Notice context: A formal introduction may invite a handshake; a crowded, casual, or sensitive situation may not.
Respect boundaries: If someone declines or does not respond, continue the conversation without making an issue of it.

Etiquette is not a measure of character. Someone who does not shake hands may be following a personal boundary or a custom that differs from yours; the absence of a handshake does not by itself mean hostility or disrespect.

Handshakes compared with other greetings

A handshake is one option among many. A wave or nod communicates acknowledgment without touch. A bow can convey greeting or respect in communities where it is customary. A spoken “hello” works in nearly any setting and can be paired with another gesture. These alternatives are not inferior versions of a handshake; each has its own conventions and meaning.

In professional situations, people sometimes treat a handshake as a sign of confidence or trustworthiness. That interpretation is subjective, and a person’s grip or willingness to make contact is not a reliable measure of competence, honesty, or intent. Clear communication and respectful behavior matter more than performing a particular greeting.

Frequently Asked Questions

Why do people shake hands instead of waving?

A handshake is a familiar greeting that involves mutual contact, while a wave acknowledges someone from a distance. Which one people choose depends on custom, relationship, setting, and comfort with touch.

Does a handshake mean an agreement is official?

It can symbolize agreement or conclude a conversation, but the gesture alone does not explain what was agreed. Its significance depends on the circumstances and any words or other actions around it.

Why do some people avoid shaking hands?

People may prefer not to shake hands because of personal boundaries, cultural or religious customs, accessibility needs, or other circumstances. A polite alternative greeting is a complete response.

Is a firm handshake always better?

No. A handshake should be comfortable for both people; squeezing hard is not a universal sign of confidence and can be unpleasant. A brief, natural greeting is usually more considerate.

Is shaking hands practiced around the world?

Handshakes are familiar in many places, but greetings vary widely. A nod, bow, wave, or verbal greeting may be more customary or appropriate, so it is sensible to follow local cues.
