Which technique is utilized to prevent ingrown toenails?

Trimming nails straight across is an important technique for preventing ingrown toenails. When toenails are cut in a straight line, the edges of the nail are less likely to grow into the surrounding skin as the nail grows. This method allows for the natural curvature of the toe, while also reducing the risk of the nails digging into the skin at the corners, which can lead to discomfort, inflammation, and the development of ingrown toenails.

In contrast, trimming toenails in a rounded shape can promote the nail edges growing into the skin, increasing the likelihood of ingrown toenails. Filing the edges of the toenails may smooth out sharp corners but does not address the fundamental issue of nail shape propagation. Soaking feet in warm water can help with relaxation and skin hydration but does not directly affect nail growth direction or shape. Thus, the most effective preventive measure is to trim nails straight across to maintain proper nail alignment and health.
