Mourning practices are rituals and customs that people observe after the death of a loved one. These practices can vary widely across different cultures and religions, often reflecting beliefs about life, death, and the afterlife. Common elements may include wearing black clothing, holding memorial services, and creating altars or shrines to honor the deceased. In many cultures, mourning periods are observed, during which family and friends may refrain from certain activities or celebrations. Some traditions involve specific ceremonies, such as shiva in Judaism or Dia de los Muertos in Mexico, where families gather to remember and celebrate the lives of those who have passed away.
