Why Do We Have Toenails? Exploring Their Significance and Care

Why Do We Have Toenails?

Toenails may seem like a trivial part of our body, but they are essential for our overall health and well-being. These small, hard structures found at the tips of our toes protect our toes from injuries and infections, help us maintain balance and grip, and even have cultural and fashion significance in some societies. In this article, we’ll explore why we have toenails and how to take care of them properly.

Scientific and Evolutionary Perspective

The first question that arises is why do we have toenails? Toenails serve many purposes, but their primary function is to provide protection and support to our feet. They help us maintain balance, grip, and stability while walking or running, especially on uneven or slippery surfaces. In evolutionary terms, toenails evolved from claws in primate ancestors and helped them climb trees and grab or hold objects.

Today, different animals use their toenails for various purposes, such as digging, climbing, or hunting. Some animals, like cats, use their retractable claws for self-defense or catching prey, while others, like primates, have flat fingernail-like claws. Our toenails have become flattened over time as we no longer need them for climbing or other physical activities.

Recent studies have revealed interesting facts about toenails, such as how they grow at different rates depending on their location on the foot, how their thickness varies with age and health, and how they can provide clues about various medical conditions. For example, thick, yellow, and brittle toenails may indicate a fungal infection or other underlying health problem.

Practical Tips for Toenail Maintenance

Toenail care is essential for keeping them healthy, strong, and looking good. Here are some practical tips for toenail maintenance:

  • Trim your toenails regularly using proper toenail clippers, ideally straight across and not too short or rounded at the corners.
  • Avoid wearing tight-fitting shoes or high heels that can squeeze your toes and damage your toenails.
  • Keep your feet clean and dry, especially after sweating, swimming, or showering. Use mild soap and lukewarm water, and pat dry with a clean towel.
  • Avoid walking barefoot in public places or sharing nail clippers or files with others, as it can increase the risk of fungal infections.
  • If you have any toenail concerns, such as ingrown toenails, thickening, or discoloration, seek medical attention promptly.

Ingrown toenails occur when the nail grows into the skin, causing pain, inflammation, and infection. To prevent ingrown toenails, avoid trimming them too short or rounding the corners, wear comfortable shoes, and avoid injuring your toes. If you have an ingrown toenail, soak your feet in warm water with Epsom salt, gently push back the skin, and elevate the affected foot to reduce swelling.

Fungal infections are another common toenail concern, especially in warm and humid climates. To prevent fungal infections, keep your feet clean and dry, avoid wearing tight-fitting or non-breathable shoes, and use antifungal creams or powders if necessary. If you have a severe fungal infection, your doctor may prescribe oral antifungal medications or recommend toenail removal in rare cases.

Cultural Significance of Toenails

Toenails have cultural significance in many societies, dating back centuries or even millennia. In some cultures, toenails are considered a symbol of beauty, health, or status, and are painted, decorated, or enhanced in various ways. In other cultures, toenails are used for medicinal purposes, such as treating headaches, fever, or digestive problems.

For example, in ancient Egypt, women painted their toenails with henna and other plant extracts to signify their social class and role. In China, toenails were used for acupuncture and reflexology to treat various ailments. In some Native American cultures, toenails were adorned with feathers, beads, or other natural materials to honor their spirituality and connection to nature.

Today, toenail fashion has become a popular trend, with many people experimenting with different colors, shapes, and designs to reflect their personality and style. From French pedicures to neon nail art, there are countless toenail trends to choose from. However, it’s essential to prioritize your toenail’s health and safety over fashion, especially if you’re prone to toenail problems or infections.

The Role of Toenails in Athletics and Sports

For athletes and sports enthusiasts, toenail care is crucial for preventing injuries and maximizing performance. Whether you’re a runner, dancer, or soccer player, your toenails can affect your comfort, agility, and speed. Ill-fitting shoes, improper trimming, or excessive pressure can lead to blisters, calluses, or toenail loss, which can impact your training and competition.

Here are some tips for athletes on toenail care and injury prevention:

  • Choose the right shoes for your sport or activity, with adequate cushioning, support, and flexibility.
  • Trim your toenails properly, with straight cuts and not too short or long.
  • Wear moisture-wicking socks to keep your feet dry, and change them frequently.
  • Stretch your feet and toes before and after exercise to reduce the risk of injuries.
  • If you experience toenail pain, swelling, or bleeding, seek medical attention and rest until you recover fully.

Some sports are more prone to toenail problems than others. For example, runners often experience black toenails, which result from repeated impact and pressure on the nails, while ballet dancers may develop blisters or calluses from pointe shoes. Being aware of the specific risks and taking preventive measures can help athletes stay on top of their game and avoid toenail problems.

Historical Perspective on Toenail Care and Fashion

The history of toenail care and fashion spans many cultures and periods, reflecting changing attitudes towards beauty, hygiene, and social norms. In ancient Egypt and Greece, toenails were colored with natural pigments like indigo or alkanet to enhance their appearance. During the Renaissance period, toenails were cut straight across and filed into various shapes, with gold or silver ornaments for the wealthy.

In the 20th century, toenail care and fashion became more mainstream, with the invention of toenail clippers, nail polish, and other grooming tools. During the 1950s and 1960s, painted toenails became a popular trend among women, with bright and contrasting colors to match their outfits. In the 21st century, toenail art and natural nail care have gained popularity, with many people opting for minimalist or eco-friendly options.

The future of toenail care and fashion seems to be moving towards more customized and sustainable solutions, with advancements in technology and materials. From 3D-printed toenails to biodegradable nail polish, there’s a growing demand for innovative and ethical products that cater to diverse needs and preferences.


Toenails may seem insignificant, but they serve many crucial functions for our health, wellness, and self-expression. Whether you’re an athlete, a fashionista, or simply someone who wants to take care of their feet, knowing how to maintain your toenails properly can make a significant difference. From trimming and cleaning to preventing injuries and infections, there’s a lot you can do to enhance your toenails’ beauty and functionality.

Remember, your toenails are an essential part of your body, and you should treat them with care and respect. If you have any concerns or questions about your toenails, don’t hesitate to consult a doctor or specialist for expert advice.
