Lines of the hand

The lines on the hand, known as palm lines, are ridges and creases that run across the palm's surface. They are primarily the heart line, head line, and life line, each representing different aspects of a person’s emotions, intellect, and vitality. These lines develop from the fetal stage and remain relatively stable over time, though they can change slightly with age or life experiences. While some view them as reflections of personality, scientifically they are primarily a pattern of skin ridges; their significance varies across cultures and beliefs.
