It’s a common misconception that nails grow faster in the sun. While exposure to sunlight does have some benefits for nails, it doesn’t actually speed up the growth process.
Nails are made of a tough protein called keratin, which is produced by the cells in the nail bed.
The rate at which these cells produce keratin is determined by a number of factors, including genetics and overall health.
Although sunlight can help improve circulation and strengthen nails, it won’t make them grow any faster.
The jury is still out on this one, but there are some compelling arguments for why nails might grow faster in the sun.
For one, the sun is a source of Vitamin D, which is essential for healthy nails (and bones). Additionally, the heat from the sun can help to improve circulation, which could also lead to healthier nails.
Of course, there are some downsides to spending too much time in the sun – you could get dehydrated or sunburned – so make sure to take breaks and stay hydrated if you’re going to be out in the sun for extended periods of time. And if your nails do seem to be growing faster in the sun, enjoy it while it lasts!

Do Nails Grow Faster in the Sun
There is no scientific evidence to support the claim that nails grow faster in the sun. However, some people believe that this is the case because they have observed that their nails seem to grow more quickly during the summer months when they are exposed to more sunlight.
It is possible that the increased circulation and blood flow caused by exposure to sunlight may contribute to faster nail growth.
Additionally, warmer weather can make nails softer and easier to trim, which may give the appearance of them growing more quickly.
Does Exposure to Sunlight Help Promote Nail Growth
There are a lot of old wives’ tales out there about how to make your nails grow faster. Some people swear by rubbing lemon juice on their nails, while others say that soaking your nails in olive oil can do the trick. But what does the science say?
Does exposure to sunlight actually help promote nail growth? Here’s what we know: our bodies need vitamin D for a whole host of reasons, including maintaining strong bones and teeth and keeping our immune system functioning properly.
And it just so happens that one of the best ways to get vitamin D is by exposing our skin to sunlight.
So, does this mean that if you want healthier, faster-growing nails, you should head outside for some sun time?
Maybe. While there’s no direct evidence that sunlight helps promote nail growth specifically, we do know that vitamin D is important for overall health, and exposure to sunlight is one of the best ways to get it.
So it stands to reason that getting enough vitamin D could indirectly lead to healthier nails. Of course, there are other things you can do to promote healthy nail growth, like eating a balanced diet and taking supplements like biotin or fish oil (which are thought to improve nail strength).
But if you’re looking for an excuse to spend more time outdoors in the sunshine, promoting healthy nail growth might just be one more benefit!
Are There Any Benefits to Letting Your Nails Soak in the Sun
There are a few benefits to letting your nails soak in the sun. Sun exposure can help improve circulation and increase blood flow to the nails, which can promote healthy nail growth.
Additionally, the UV rays from the sun can help kill bacteria that may be present on the nails or in the nail bed, helping to keep your nails clean and free of infection.
Finally, soaking your nails in the sun can also help to soften and loosen any hardened skin on the nails or cuticles, making them easier to trim and care for.
