It is a well-known fact that human nails grow indefinitely, and this continuous growth serves an important purpose. Nails protect our fingers from damage and can regrow if broken or worn out. While the rate of nail growth varies depending on factors such as hand dominance, age, hormone levels, and overall health, the average growth rate is about a tenth of a millimeter per day. Interestingly, some people's nails may appear to grow longer after death due to the skin shrinking and pulling back from the nails. On the other hand, nail growth can be impacted by various medical conditions and nutritional deficiencies, and certain changes in nail appearance may signal underlying health issues. Maintaining good nail hygiene, including moisturizing and keeping nails trimmed, is essential for nail health.

What You'll Learn
The evolutionary purpose of nails
The human body is an incredible machine, and even the smallest parts, like our nails, serve a significant purpose. Nails are made of a tough protein called keratin, which also makes up our hair and the outer layer of our skin. From an evolutionary perspective, nails have played a crucial role in our survival and adaptation.
One of the primary functions of nails is to protect the sensitive nerve endings in our fingertips. Our nails act as a barrier, shielding these delicate areas from damage and infection. This protective function is especially important for our thumbs and index fingers, which have a particularly dense concentration of nerve endings. By having nails, we can manipulate small objects, pick at things, and perform precise tasks without constantly injuring these sensitive areas.
Nails also provide us with an enhanced sense of touch. The white crescent moon shape at the base of the nail (lunula) contains specialized nerve cells that detect even the slightest changes in pressure. These nerves send signals to the brain, providing us with tactile feedback. This heightened sense of touch would have been advantageous for our early ancestors, who relied on their hands for survival, whether it was through hunting, gathering, or crafting tools.
In addition to protection and sensory functions, nails also serve an aesthetic purpose. In many cultures, well-groomed nails are considered a sign of hygiene, health, and even social status. This is not merely a modern human concern; some anthropological evidence suggests that even early hominins may have recognized the social and health implications of well-maintained nails.
Finally, nails can also provide clues about our overall health. Changes in nail texture, color, or shape can indicate underlying health conditions, including nutritional deficiencies or liver and heart disorders. This diagnostic function is unique to nails and showcases their importance beyond simple physical protection and sensory enhancement. Thus, the existence of nails on our fingers and toes is not merely a coincidence but rather a testament to their evolutionary significance.

Factors affecting nail growth
Several factors influence the growth of nails, which, on average, grow about a tenth of a millimeter per day. Firstly, physical damage to the nail matrix, the structure at the base of the nail where nail growth originates, can slow down growth. For example, deep cuts or blunt force trauma to the nail can cause onychomadesis, a condition that warrants medical attention. In addition, the nails may temporarily stop growing in response to stress in the body, such as a high fever, serious injury, infection, or severe illness.
Secondly, the growth rate of nails is influenced by age, hormone levels, and overall health. Nails tend to grow faster during the summertime and on the dominant hand. Maintaining nail hygiene, including keeping cuticles pushed back or trimmed and moisturizing, can support nail health and growth. Additionally, a balanced diet is essential for providing the necessary nutrients to promote healthy nail growth.
Furthermore, certain medical conditions can impact nail growth. For instance, clubbing, where nails curve more than usual, can indicate low oxygen levels in the blood and may be linked to lung, heart, liver, or inflammatory bowel disease. Spoon nails or koilonychia, characterized by a ski jump-like nail growth pattern, is another condition that may signal underlying health issues. Changes in nail color, such as yellow or red discoloration, or the appearance of stripes or dots, could also indicate medical problems.
While nails are designed to protect the sensitive tips of our fingers and toes, certain habits can hinder their growth. Biting, picking, and improper nail shaping can negatively affect nail growth. Keeping nails filed into a slightly rounded or squared shape can prevent breakage and support overall nail health, allowing for optimal growth.

Health conditions indicated by nails
Our nails can reveal a lot about our health. While most nail issues are harmless and can be resolved on their own or with home treatments, some may indicate underlying health conditions requiring medical attention. Here are some health conditions that can be indicated by changes in our nails:
Infections and Diseases
Nail infections, such as onychomycosis, can cause spots, discolouration, and nail separation. Fungal infections are common, leading to thick, discoloured, and brittle nails. Viral infections like warts (periungual warts) can also affect nails. Additionally, conditions like nail psoriasis can cause nail denting or crumbling, and people with skin psoriasis may experience nail symptoms.
Nutritional Deficiencies
Nutritional deficiencies can impact nail health. For example, vitamin B12 deficiency may cause nail discolouration. Nails can also develop Beau's lines, which are depressions across the nail, indicating malnourishment or vitamin and mineral deficiencies. A balanced diet that includes whole foods like fruits, vegetables, and whole grains can provide the necessary nutrients for nail health.
Chronic Conditions
Nail abnormalities may indicate chronic conditions or underlying diseases. For instance, Terry's nails, characterised by a dark band on the nail tip, can be a sign of ageing or chronic conditions. Spoon nails or koilonychia, where nails curve outward like spoons, can be associated with inflammatory bowel disease, heart disease, or liver problems. Leukonychia, or white spots or lines on the nail, can be harmless in healthy individuals but may be associated with poor health or nutritional deficiencies in other cases.
Physical Trauma and Injuries
Injuries to the fingers, hands, or nails can cause nail abnormalities. Horizontal lines on the nails, known as Mees' lines, can indicate arsenic poisoning. Onycholysis occurs when the nail separates from the nail bed, which can be due to trauma, infection, or products used on the nails. Physical damage to the nail matrix can also slow nail growth.
It is important to note that while nails can provide insights into potential health issues, a visit to a healthcare professional is necessary for proper diagnosis and treatment.

Maintaining nail health
Our nails are a window to our health, and proper nail care is important. Here are some tips for maintaining nail health:
Firstly, keep your nails clean and dry. Bacteria and fungi thrive in a moist environment, so maintaining clean, dry nails prevents bacteria from growing underneath them. Cut your nails straight across with sharp nail scissors or clippers, and slightly round the tips for added strength. Avoid biting your nails or removing the cuticle, as this can damage them.
Secondly, file your nails regularly in one direction to keep them shaped and free of snags. Use an emery board for this purpose. It is also important to protect your nails from water exposure. Too much water can weaken your nails, causing them to split, peel, or break. Wear gloves when cleaning or washing dishes, and make sure to moisturize your hands and nails afterward.
Thirdly, a balanced diet should provide all the nutrition your nails need. Ensure you are eating a nutrient-dense and varied diet, including foods high in protein. Drinking enough water throughout the day is also essential for nail health. Without adequate moisture, nails can become brittle and break and peel easily.
Lastly, be mindful of any changes in your nails, such as swelling, pain, or discoloration, as these can indicate underlying health issues. For example, clubbing of the nails, when they curve more than usual, can be a sign of low oxygen levels in the blood and may be related to lung, heart, liver, or bowel disease. If you notice any nail changes, it is important to consult a dermatologist or healthcare provider for advice and treatment.

What to do if your nails stop growing
If your nails have stopped growing, there are several factors that could be at play. Firstly, it is important to consider any physical trauma to the nail, such as a deep cut or heavy blunt impact, which may have damaged the nail matrix and slowed growth. In such cases, it is advisable to consult a healthcare professional to assess the risk of onychomadesis and provide appropriate treatment.
Additionally, certain underlying medical conditions can cause changes in nail growth. For instance, clubbed nails, which curve more than usual, can indicate low oxygen levels in the blood and may be linked to lung, heart, liver, or inflammatory bowel disease. Spoon nails, or koilonychia, is another condition where nails grow in a ski-jump pattern. Changes in nail colour, such as yellow or red stripes or dots, may also signal an underlying issue.
Stress, high fever, serious infections, or other severe illnesses can also cause your nails to temporarily stop growing. Furthermore, nutritional deficiencies can impact nail growth, so ensuring a balanced diet is important. Nails need a variety of nutrients, including those found in lotions or oils containing jojoba oil, vitamin E, or shea butter, which can help keep them moisturized, healthy, and flexible.
Practicing good nail hygiene can also support nail health and growth. This includes keeping nails filed into a slightly rounded or squared shape to prevent snagging and breaking, as well as maintaining trimmed cuticles and moisturized nail beds. These simple steps can help encourage nail growth and prevent further complications.
