What can prolonged exposure to water do to nails?

Prolonged exposure to water can weaken nails and lead to splitting due to the way water affects the structure of the nail. Nails are composed mostly of keratin, a protein that can absorb moisture. When nails are frequently submerged in water or exposed to high humidity, they can become overly saturated, causing them to swell. This swelling disrupts the integrity of the nail, making them more prone to damage and splitting.

In addition, the consistent moisture can weaken the adhesive properties of any coatings or enhancements, which contributes to further deterioration of the nail surface. Those who regularly perform tasks involving water exposure may notice this weakening effect, leading to an increased risk of nail breakage.

The other options suggest benefits of water exposure to nails, which do not reflect the reality of nail health. While hydration is vital for overall health, the condition of nails specifically suffers from excessive moisture without proper care or protection.
