Many factors influence how fast your nails grow, from the time of year to how old you are, and even which hand the nail is on. It is commonly believed that sun exposure makes nails grow faster. While there is no scientific proof of this, it is true that exposure to sunlight is essential for overall health, as it helps the body produce vitamin D, which is important for nail growth.

What You'll Learn
Sun exposure and nail growth correlation
It is believed that sun exposure plays a role in nail growth. Many people have observed that their nails grow faster during the summer or after spending time in sunny places. While there is no scientific evidence directly linking sunlight to nail growth, there are several factors related to sun exposure that may influence nail growth.
Firstly, the sun helps the body produce vitamin D, which is essential for overall health, including nail health and growth. Increased sun exposure during the warmer months can lead to improved blood circulation and higher metabolic activity, which may contribute to faster nail growth. Additionally, people tend to be more active during the summer, engaging in activities that enhance blood flow to the extremities, including the hands and feet. This increased blood flow can provide more nutrients to the nails, supporting their growth.
However, excessive sun exposure without protection can have negative effects on the nails and surrounding skin. Prolonged sun exposure can cause sunburns and dry out the cuticles, affecting nail growth. Sun damage can also lead to the formation of vertical ridges in the nails, which can take several months to grow out. Therefore, while sun exposure may indirectly influence nail growth through improved circulation and vitamin D production, it is important to maintain a balance and protect the nails and skin from excessive sun damage.
Apart from sun exposure, there are other factors that can influence nail growth. Nails on the dominant hand tend to grow faster due to more frequent use, which increases the risk of trauma and stimulates the body to send more blood and nutrients to the area, promoting nail growth. Additionally, the rate of nail growth depends on the specific finger, with little fingers' nails growing slower than others. Frequent nail clipping can also encourage faster nail growth, as it removes any weak ends that may break off and slow down overall growth.

Nutritional deficiencies and nail growth
While some factors that affect nail growth are outside of our control, nutritional deficiencies can play a role in nail growth and overall nail health. Nails are considered a mirror of the body's internal constitution and nutritional status. Nutritional deficiencies can cause nail changes, including softness, weakness, and discolouration.
Protein deficiency, for example, can cause Beau's lines, which are transverse linear depressions in the nail plate. These lines indicate a disruption in normal nail growth and can be caused by any severe disease. Kwashiorkor, a nutritional syndrome caused by severe protein malnutrition, can result in soft and thin nails. Marasmus, a wasting syndrome caused by prolonged starvation, can lead to fissured nails and impaired nail growth.
Iron deficiency can also impact nail health, causing brittle nails and spoon nails, a condition where the nail appears concave. Additionally, vitamin B12 deficiency may cause nail discolouration. Weak nails may also be associated with a deficiency in calcium and B vitamins.
It is important to note that nail issues can also occur due to injury, overexposure to moisture, or external factors such as the use of certain chemicals or nail treatments. If you are concerned about your nail health, it is recommended to consult a doctor or a healthcare professional. They can help determine the underlying cause and advise on any necessary steps to improve nail health.

Toenail vs. Fingernail growth rate
Sun exposure has been linked to faster nail growth. Many people have reported that their nails grow faster in the summer or after moving to a sunnier country. While there is no scientific proof of specific methods to make nails grow faster, there are ways to increase overall nail health, such as taking biotin.
On average, fingernails grow faster than toenails. Fingernails grow at a rate of about 3.47 mm per month, or about a tenth of a millimeter per day. Toenails, on the other hand, grow at a slower rate of approximately 1.62 mm per month. This difference in growth rate may be attributed to the fact that fingernails are more prone to trauma, such as catching on something or being hit, which stimulates circulation in the nail bed and increases nail growth.
The rate of nail growth also varies depending on which finger or toe the nail is on. For example, the little finger's nail grows slower than the other fingernails, while the big toe's nail grows faster than the other toenails. Additionally, the nails on the dominant hand tend to grow faster, possibly due to increased use and trauma.
Age, hormone levels, and overall health also influence nail growth rates. Nail growth is said to peak during puberty and decline as hormone levels balance out with age. Blood circulation slows down as we age, affecting the speed of nail growth.

Blood circulation and nail growth
While sun exposure does not directly influence nail growth, it is essential for our overall health and well-being. Sunlight helps our bodies produce vitamin D, which is crucial for nail growth. Therefore, an indirect relationship exists between sun exposure and nail growth.
During the summer, nails may grow faster due to increased blood circulation and metabolic activity. Warmer temperatures encourage people to be more active and engage in activities that stimulate blood flow to the extremities, including the hands and feet. This increased blood flow delivers essential nutrients to the nails, supporting their growth.
Additionally, the nails on our dominant hand tend to grow faster because we use that hand more often. This frequent use increases the risk of trauma, such as catching our nail on something or hitting it accidentally. In response to such trauma, our body naturally increases blood flow and nutrient supply to the affected area, promoting repair and potentially accelerating nail growth.
Good nail hygiene practices and overall hand care are also important for nail health and growth. Cuticles, which cover the base of the nails and protect new nail growth, can dry out, impacting nail growth. Keeping them moisturized and protecting them from excessive sun exposure can help maintain nail health.
While sunlight may contribute to faster nail growth indirectly, it is important to remember that excessive sun exposure without protection can be detrimental. Sun damage can cause vertical ridges in the nails, and drying out the nails and surrounding skin, affecting their growth. Therefore, while enjoying the sun, it is crucial to practice sun protection and maintain proper nail and hand care.

Sun protection for nails
Sun exposure has been linked to faster nail growth, with many people reporting that their nails grow faster in the summer or after moving to a sunnier climate. While this may be the case, it is important to remember that the sun's ultraviolet radiation can also cause damage to your skin and nails.
- Apply sunscreen to your hands and nails: Use a broad-spectrum sunscreen with a high SPF and remember to reapply every couple of hours or after swimming. There are also sunscreens specifically formulated for hands and nails that can provide extra protection.
- Wear sun-protective gloves: Invest in a pair of UPF 50+ gloves to block most of the harmful UVA and UVB rays from reaching your skin and nails.
- Choose a beach-inspired nail polish colour: Opt for shades that complement the seaside atmosphere, such as vivid orange or soft, ultra-light beige.
- Prepare a nail emergency kit: Carry a small kit with you to the beach to quickly touch up any chips or wear on your nails. Use light, thin layers and allow each coat to dry before applying the next.
- Restore moisture: After a day in the sun, sand, and saltwater, be sure to moisturize your nails and cuticles to prevent dryness and maintain their health.
In addition to sun protection, there are other ways to promote nail health and growth. Maintaining good nail hygiene and addressing any nutritional deficiencies can help. Regular nail clipping can also stimulate growth without the same risks as nail biting. Taking biotin supplements may also strengthen your nails and prevent them from breaking.
