Eye puffiness can be caused by physiological or pathological factors. Physiological causes may include poor sleep, an unsuitable pillow, or crying for too long. Pathological causes can be inflammation (recurrence of eye inflammation) or non-inflammatory conditions (allergies, heart disease, hypothyroidism, nephritis, etc.). During treatment, it is important to pay attention to diet, maintain a regular schedule, actively participate in physical exercise, adjust mental and physical health, and maintain good personal hygiene to avoid bacterial invasion.
