Hand gestures are everywhere—so ingrained in our daily lives that we often don’t realize how frequently we communicate through them. Whether expressing emotions, adding context to our words, or simply enhancing spoken communication, gestures are a vital part of our shared culture, passed down through generations for centuries. From ancient Rome to the modern day, here are 12 hand gestures and their fascinating origins explained.

The exact origins of the thumbs-up gesture remain uncertain, but its earliest documented use dates back to Roman gladiators, where a thumbs-up or thumbs-down was believed to signal life or death in the arena. Today, the gesture is nearly universal, thanks to its popularization through media, travel, and even emojis. However, it carries offensive meanings in certain cultures, and for divers, it signifies "ascend," rather than approval—so context matters!

Believe it or not, the V sign originally began as an insulting gesture, though with the back of the hand facing outward. A more positive meaning, however, was popularized during World War II when Winston Churchill used it as a "V for Victory" symbol. The double-entendre of the gesture likely added to its appeal—flipping the hand’s orientation easily turned it into a mocking snub toward the enemy. In the 1960s, the gesture took on new meaning during the counterculture movements, evolving into an enduring symbol of peace.

The wave as a friendly greeting traces back to medieval times when knights raised their visors to show they meant no harm. Its simplicity and universal appeal have made it a common gesture worldwide, transcending language barriers. However, in some countries like Nigeria and South Korea, certain types of waving can still carry offensive connotations.

The handshake might be one of the oldest hand gestures on this list, so it’s hard to be sure of its origins. Yet, there is evidence that it was already in use 3,000 years ago, as a way to seal alliances. In ancient Greece it was called dexiosis, and was practised as early as the 5th century BC. While the gesture is found in many cultures, the specifics as to when and how it should be used vary significantly.

Pointing likely originated as a practical gesture to indicate objects or directions, making it one of humanity's oldest forms of communication. Fascinatingly, it is the first communicative gesture to develop in human infants, and linguists believe it plays a crucial role in language acquisition. However, despite its universal utility, many cultures consider pointing at other people with the index finger to be rude or disrespectful.

The military salute, like the wave, originates in the medieval practice of knights raising their helmets as a gesture of recognition and peaceful intentions. By the 18th century, it had evolved into a formal military custom to signify respect and camaraderie. Today, variations of the salute can be seen across armed forces worldwide, each adapted to reflect the unique traditions and protocols of different nations.

While the phrase "give me five" was already slang for a type of handshake, the high five most likely evolved from the "low five," a gesture rooted in African-American culture since the 1920s. The first documented use of the high five occurred in 1977, credited to Dusty Baker and Glenn Burke of the Los Angeles Dodgers. It quickly became associated with sports, symbolizing shared triumphs and camaraderie.

The fist bump can trace its origins to boxers who were instructed to touch gloves at the start of a contest. However, its popularization is a relatively recent phenomenon, gaining traction in sports and youth culture during the 1990s as a more casual alternative to the handshake. During the COVID-19 pandemic, the fist bump became a common greeting, as shaking hands was discouraged to help slow the spread of the virus.

While the origins of clapping as a form of applause are difficult to pinpoint, it is a common practice in many cultures. One of its earliest documented uses dates back to ancient Roman theater, where audiences clapped or waved pieces of cloth to express approval for performances. The percussive sound of clapping has also found its place in music, particularly in genres like funk, gospel, doo-wop, and flamenco.

The "OK" gesture, made by forming a circle with the thumb and index finger, became popular in 19th-century America as a symbol for "all correct." However, its origins trace back to classical antiquity, where a thumb and forefinger touching was thought to mimic kissing lips, often used as a romantic gesture. It wasn’t until Roman rhetoricians began using it during public speeches that the gesture gained its modern connotation of approval or assent.

The crossed fingers gesture, often used to wish for luck, has its origins in ancient Christianity, where it was likely adopted for its resemblance to the Cross of Christ. Over time, it also became associated with telling lies, especially among children who use it as an excuse for telling a white lie or invalidating a promise.

Though likely as old as human frustration itself, the facepalm gesture became globally famous through internet memes, becoming a shorthand for disappointment or exasperation in both real life and online. Surprisingly, it’s not exclusive to humans—primates have been observed using similar gestures to signal a desire for solitude or to avoid social interaction.

What science says

It was false after all: 10 health myths that sound true—but aren't

Health myths are everywhere! These ideas were simply passed down for so long that they became part of what we believed. But now science has stepped in to clear things up. Does cold weather make you sick? Can lemon detox your body? Is reading in low light really harmful? Let's uncover the truth behind 10 common health myths!

Have you ever been told that cutting your hair will make it grow faster? We're sorry to say that's just a myth. Hair grows from the root, not the ends. So, trimming it won't boost growth, though it does help remove split ends that can make your hair look dry or unhealthy.

This is one of the most common health myths. Cold weather often gets blamed, but it's not the temperature that makes you catch a cold. During winter, we tend to stay indoors with others and keep the windows closed, an environment that makes it easier for viruses to spread. That's why colds tend to be more common in winter!

The idea that eating before bed automatically leads to weight gain is a myth. In reality, it has more to do with what you eat and how much, rather than the time of day. Often, when we eat very late at night, we're tired and more likely to reach for quick, high-calorie, heavy foods. This can disrupt sleep and lead to consuming more calories than we burn, both of which may affect weight. If it's close to bedtime, it's better to have something light and healthy in a moderate portion than to skip a meal altogether.

Does wearing glasses weaken your vision? Myth! If an eye doctor prescribes glasses, wearing them as directed helps correct your vision; it won't make it worse. Additionally, the right glasses can help prevent or reduce headaches caused by reading or spending long hours in front of a screen.

This myth is closely related to the previous one. If you love reading and sometimes have to do it in low light because of the situation, don't worry. According to experts, reading in low light doesn't cause permanent or irreversible eye damage. However, it's not recommended because it can make your eyes feel tired or strained, leading to discomfort or headaches.

We're all different, and so are our bodies. The idea that everyone should drink exactly eight glasses of water a day is more of a general guideline than a rule. Staying well hydrated throughout the day is extremely important, but how much water you need depends on factors like your weight, age, climate, and overall health. We should prioritize staying consistently hydrated instead of obsessing over the number of glasses we drink.

Some people say drinking lemon water helps eliminate toxins and cleanse the body. While adding a slice of lemon to your water is a refreshing way to stay hydrated, it doesn't have any special "detoxifying" powers. The vitamin C in citrus fruits is beneficial, but the body has its own natural detox system. The liver and kidneys are the main organs that filter waste and eliminate toxins.

Not all fats are bad! Just like other food groups, your body needs fats to function properly. The important thing is knowing the difference between healthy fats and those that can be harmful. Foods like avocados, seeds, olive oil, fish, and nuts are rich in healthy fats. On the other hand, the fats found in processed or fried foods are the ones that can have a negative impact on your body.

Liver diseases can be serious. While heavy and frequent consumption of alcohol and fats is a major contributor, it's not the only cause. Liver problems can also result from many other factors. These include viral infections, autoimmune diseases, genetic disorders, high blood pressure, and exposure to certain chemicals.

There's some truth to it: breakfast is important because it replenishes our glucose and energy levels and supports proper metabolism. However, the idea that it's the most important meal of the day might be an exaggeration. Everyone's body has different needs, and all meals are important, so we shouldn't skip any of them!
