Water is an essential component of nail health, as nails contain 7-12% water, and proper hydration is key to nail growth. However, prolonged exposure to water can weaken nails, making them soft, brittle, and prone to breakage. This is because water causes the nail plate to expand, and when the water evaporates, the nail plate shrinks back to its original size, exposing and exacerbating small fractures. Therefore, while water is necessary for nail health, excessive exposure can negatively impact nails.

What You'll Learn
Water can weaken nails, making them brittle
While water is an essential component of healthy nails, as they are composed of 7-12% water, and hydration is critical for nail health, overexposure to water can have detrimental effects. Prolonged exposure to water can cause nails to become weak and brittle, making them more prone to breakage. This occurs because the nail plate expands when soaked in water, and when the water eventually evaporates, the nail plate shrinks back to its original size. This shrinkage exposes and enlarges any small fractures present in the nail.
To prevent this, it is recommended to always dry nails thoroughly after swimming or showering. Wearing gloves can also help protect the nails from excessive water exposure during activities such as washing dishes, clothes, or surfaces. Keeping nails filed into a slightly rounded or squared shape can prevent them from snagging and breaking. Additionally, maintaining proper nail hygiene by regularly washing, drying, and oiling the nails is crucial for preventing bacterial and fungal growth.
It is worth noting that while water can weaken nails, other factors can also contribute to brittle nails. Nutritional deficiencies, particularly a lack of iron, can result in nail brittleness. Medical conditions such as diabetes can also reduce circulation to the nails, making them weaker and more susceptible to breakage. Changes in nail colour, texture, or growth rate can often serve as indicators of underlying health issues. Therefore, it is important to pay attention to any unusual symptoms and consult a doctor if concerns arise.
Furthermore, stress can influence nail health and growth. Stress has been linked to slower nail growth and can even temporarily halt nail growth. When nails resume growth after a stressful period, horizontal lines may appear across the nails. Additionally, nail biting, using nails as tools, and exposure to harsh chemicals can damage nails and hinder their growth. Protecting nails from these external factors and maintaining a well-balanced lifestyle can promote overall nail health and strength.

Nails are made of keratin, a protein
Keratin is a key part of many glands and lines internal organs. It forms the hard part of the nail, called the nail plate, which does not consist of living tissue. The nail plate is much like hair, made primarily from keratin. The nail bed is the tissue underneath the nail, and this is where nail growth begins. As new cells grow, they push old ones through your skin. The part you can see consists of dead cells, which is why it doesn't hurt to cut your nails.
Good nail hygiene can help promote nail growth. Nails grow faster in the summer than in the winter, and on your dominant hand. Keeping your nails filed into a slightly rounded or squared shape can prevent them from snagging and breaking. Water can weaken nails, making them soft and brittle, so it's important to dry your nails thoroughly after swimming or showering.
A balanced diet is also important for healthy nail growth. This should include protein, water, fruits, vegetables, and a wide array of vitamins and minerals. Some specific dietary changes can strengthen the nails and promote growth, such as supplementing with calcium and vitamin D.

Puberty is when nail growth peaks
Fingernails grow at an average rate of 3.47mm per month, or about a tenth of a millimeter per day. However, this rate is subject to variation due to several factors, including age, health, nutrition, and genetics.
During puberty, the body undergoes various physiological changes, and nail growth is one of the many processes influenced by this hormonal shift. The exact mechanism by which hormones affect nail growth is not fully understood, but it is believed to be related to the increased blood circulation that occurs during this time.
While puberty is a critical phase for nail growth, it is not the only factor that determines nail health and growth rate. Overall health, nutrition, and certain medical conditions also play a role. For instance, peripheral artery disease can reduce blood flow to the nails, slowing their growth. Additionally, illnesses like COVID-19 or pneumonia can interrupt nail growth and cause horizontal ridges known as Beau's lines.
To support nail health and promote optimal growth, maintaining a healthy and balanced diet is essential. A diet rich in proteins, omega-3s, iron, calcium, biotin, and vitamins can contribute to stronger and healthier nails. Staying hydrated is also important, as water helps maintain overall health, which indirectly impacts nail growth. However, prolonged exposure to water can weaken nails, making them soft and brittle, so it is crucial to dry nails thoroughly after swimming or showering.

Nails grow faster in summer
Fingernails grow at an average rate of about 3.47 millimetres per month or 0.1 millimetres per day. However, there are several factors that influence the speed of nail growth. Nails grow faster in the summer than in winter, although the reason for this is not yet fully understood. One theory is that cold weather slows down nail growth.
Nails on the dominant hand tend to grow faster, as they are more prone to minor trauma, such as tapping them on a table or using a keyboard. This promotes blood circulation in the hands, which stimulates nail growth. Similarly, nail biting and clipping have been associated with faster nail growth, as the trauma caused to the nail encourages the body to send more blood and nutrients to the area to aid repair.
Good nail hygiene, such as keeping nails trimmed and moisturising the hands and nails, can also support nail growth. A varied and nutritious diet, including protein, water, fruits, vegetables, vitamins, and minerals, is important for healthy nails. For example, people who do not get enough iron may experience brittle or dented nails.
While there is no proven way to make nails grow faster, maintaining healthy nail beds, matrices, and surrounding skin can help nails grow longer and stronger. The nail bed is the tissue underneath the nail, and the matrix is the structure at the base of the nail where nail growth begins.

Good nail hygiene helps growth
Good nail hygiene is essential for maintaining healthy nails and promoting their growth. Nails grow from underneath the skin, and certain factors, such as nutrition, age, and underlying health conditions, can influence their growth rate. While there is no proven way to make nails grow faster, good nail hygiene can help strengthen nails and prevent breakage, allowing for optimal growth.
Maintaining clean and dry nails is crucial for good nail hygiene. Dirt, bacteria, and fungi can accumulate under nails, particularly if they are long, leading to infections. Therefore, it is recommended to keep nails short and trim them regularly. When washing hands, scrub the underside of the nails with soap and water, and consider using a nail brush. This helps prevent the buildup of dirt and bacteria, reducing the risk of nail infections.
Nail grooming tools, such as nail clippers and files, should be sanitized before each use to avoid the spread of germs. It is also important to avoid biting nails and cutting cuticles, as this can damage the nail and increase the risk of infection. Instead, keep the cuticles pushed back or trimmed, and moisturize the nails and surrounding skin regularly to prevent dryness and maintain nail health.
Additionally, protecting nails from excessive water exposure is essential. Water can weaken nails, making them soft, brittle, and prone to splitting, peeling, or breaking. Wearing gloves when performing tasks such as washing dishes or cleaning can help prevent water damage to nails. Keeping nails filed into a slightly rounded or squared shape can also prevent snagging and reduce the risk of breakage.
Good nail hygiene practices, combined with a balanced diet that includes essential nutrients like protein, water, fruits, vegetables, vitamins, and minerals, can promote nail health and support their growth. By following these hygiene and dietary tips, individuals can help strengthen their nails, prevent breakage, and create optimal conditions for nail growth.
