Small pits in the fingernails can be improved by replenishing the nutrients that the body lacks and by strengthening the body’s nutrition and taking care of rest, which can also improve malnutrition. In addition, you can improve the symptoms of small pits by increasing the concentration of inhaled oxygen and correcting hypoxemia. It is important to use more warm water in daily life and avoid prolonged contact with ice water, so that the degree of nail depression will gradually improve and heal. Heavy laborers during the day can also cause small pits in the finger nails, so pay attention to the maintenance of your fingers. When engaging in heavy work, it is important to give your fingers a moderate amount of rest or to re-choose the right type of work for you to reduce the damage done in the case of heavy work.
