Many factors influence nail growth, including genetics, overall health, and daily habits. While sunlight does not directly accelerate nail growth, it plays a vital role in vitamin D production, which is essential for nail health and growth. Increased sun exposure during summer may contribute to faster nail growth due to enhanced circulation and metabolic activity. Additionally, sunlight can protect nails from UV damage by activating keratinocytes to produce melanin, acting as a natural sunscreen. However, excessive sun exposure without protection can lead to nail and skin dryness, emphasizing the importance of sunscreen when spending time in the sun. Thus, sunlight indirectly influences nail growth by providing vitamin D and protecting nails from UV damage, contributing to overall nail health.

What You'll Learn
Sunlight and vitamin D
Sunlight plays a role in nail growth, but not directly. One of the reasons nails may grow faster in the summer is because of increased blood circulation and overall metabolic activity during warmer months. People might also be more active and engage in activities that stimulate blood flow to the extremities.
The sun does, however, provide us with vitamin D, which is important for nail growth. Vitamin D plays a vital role in the growth and maintenance of nails, and sunlight is one of its easiest sources.
It is important to note that excessive sun exposure without protection can lead to damage, including drying out the nails and surrounding skin. Therefore, it is recommended to use sunscreen to protect your skin and nails when spending time in the sun.
In addition to sunlight, vitamin D can also be obtained through other sources. For example, mild winters and hot summers can help create vitamin D, which is beneficial for nail growth. Additionally, vitamin D supplements are available for those who may not get enough sun exposure.
Overall, while sunlight may not have a direct impact on nail growth, it is important for overall health and can contribute to nail growth through the production of vitamin D.

Genetics and health
While nail growth is primarily determined by genetic factors and overall health, sunlight does play a role in nail growth. Sunlight helps the body produce vitamin D, which is important for nail growth. Nails may also grow faster in the summer due to increased blood circulation and metabolic activity. Additionally, people might be more active during the warmer months, engaging in activities that stimulate blood flow to the extremities.
Genetics play a significant role in determining the size and shape of nail beds. Nail growth is also said to peak during puberty and decline as hormone levels balance out with age. Cell reproduction slows down as people get older, reducing the production of new nail cells and resulting in slower nail growth.
Overall health is another critical factor influencing nail growth. Nutritional deficiencies can affect the appearance of nails. Ensuring adequate nutrient intake and addressing any deficiencies can promote nail health and growth. For example, biotin, a B vitamin, is known to enhance nail health and strength, reducing breakage. It can be found in foods such as cooked eggs, sardines, nuts, cauliflower, bananas, and mushrooms or taken as a supplement.
Additionally, maintaining healthy cuticles is vital as they protect nails as they grow. Moisturising the hands and using cuticle oils can help achieve this. While nail hardeners can strengthen nails and prevent breakage, they should be used sparingly as prolonged use can break down the nail over time.
Certain medical conditions, such as diabetes or circulatory issues, can impact nail health and growth. Monitoring nail health and seeking medical advice when necessary are important. Trauma to the nail, such as through nail-biting or nail injuries, can also affect growth. Nail biting stimulates circulation in the nail bed, potentially increasing nail growth. However, it is essential to consider the risks associated with nail biting, and regular nail clipping is recommended as a safer alternative.

Nail trauma and circulation
While exposure to sunlight does not directly influence nail growth, it is crucial for the overall health of an individual. Sunlight helps the body produce vitamin D, which is essential for nail growth. Nails may grow faster in the summer due to increased blood circulation and metabolic activity. However, it is important to note that excessive sun exposure can lead to nail and skin damage.
Nail trauma refers to any injury to the nail, which can range from a bruise under the nail to the separation of the nail from the nail bed. One common type of nail trauma is a subungual hematoma, which is a collection of blood under the nail that causes severe throbbing pain. It typically occurs due to blunt force or crush injuries, such as hitting your nail with a hammer or dropping a heavy object on your toe. Subungual hematomas can also result from repetitive pressure, such as wearing tight-fitting shoes that press on your toenails.
The treatment for a subungual hematoma aims to relieve pressure by draining the blood trapped under the nail. While some people may attempt to drain the blood at home, it is generally recommended to seek medical care. For small hematomas, a needle or paper clip can be heated until red-hot and then used to create a small hole in the nail for the blood to drain. However, it is important to note that the nail may remain discolored even after the procedure.
Other types of nail injuries include lacerations or cuts to the nail, nail bed, cuticle, or surrounding skin. More serious injuries may involve the amputation of a portion of the fingertip or toe, including the nail. In the case of any laceration or amputation, it is crucial to seek medical attention within six hours, especially if there is bleeding under the nail that occupies more than half of the nail area, as it could indicate a potential bone fracture or tissue tear.
To prevent nail trauma, it is important to wear properly sized shoes and keep your nails trimmed. Additionally, it is recommended to be cautious when using sharp objects or machinery to avoid potential nail injuries.

Biotin and nutrition
While sunlight does not directly influence nail growth, it is essential for overall health and plays an indirect role in nail growth by helping our bodies produce vitamin D, which is crucial for nail growth and maintenance.
Biotin, also known as vitamin B7, is a water-soluble vitamin that plays a vital role in nail health and growth. It is a part of the B-complex vitamin family and is considered an essential nutrient. Biotin is naturally present in some foods, and it is also available as a dietary supplement.
Food Sources of Biotin
Biotin is most abundant in organ meats, such as liver. Other good sources include eggs, salmon, pork, beef, seeds, nuts, and sweet potatoes. Consuming a well-rounded diet that includes these foods can help ensure adequate biotin intake.
Benefits of Biotin for Nails
Biotin is often touted as a remedy for weak and brittle nails. While there is limited evidence to support this claim for individuals without a biotin deficiency, studies have shown positive results in those with a biotin deficiency. A Swiss study found that patients with brittle nails who received biotin supplementation experienced a 25% increase in nail plate thickness, indicating improved nail health and strength.
Recommended Intake
For most adults over the age of 19, a daily biotin intake of 30 micrograms is considered sufficient for optimal nail, hair, and general health. If you believe you may have a biotin deficiency, it is advisable to consult a healthcare professional for an evaluation.
In addition to biotin, other nutrients that contribute to nail health include zinc, vitamin B12, folate (vitamin B9), iron, and omega-3 fatty acids. A well-balanced diet that includes a variety of fruits, vegetables, nuts, seeds, and adequate protein sources can promote overall nail health and support nail growth.

Sun protection and nail care
While sun exposure does not directly influence nail growth, it does help the body produce vitamin D, which is essential for nail growth. However, excessive sun exposure can lead to nail damage, including drying out the nails and surrounding skin.
- Apply sunscreen to your nails and cuticles to protect them from harmful UV rays, which can cause colour fading and yellowing. Use a broad-spectrum sunscreen with a high SPF, and reapply every few hours or after swimming.
- Keep your hands and cuticles moisturised throughout the day to prevent your nails from drying out. Hydrated nails are less likely to chip or break.
- Apply a nourishing cuticle oil or cream to keep your nails and cuticles hydrated and prevent dryness.
- When removing nail polish, only soak your fingertips in acetone instead of your whole hands or fingers to protect the surrounding skin. Alternatively, use cotton balls soaked in acetone and wrap small pieces of aluminium foil around your fingertips.
- Take breaks from nail polish. Try not to wear nail polish for one to two weeks to allow your nails time to repair and rehydrate.
- If you're going to the beach, opt for a gel polish in a shade that complements the seaside atmosphere. Gels are less likely to chip or dull than regular nail polish.
