「うがい」(ugai) is a Japanese term that refers to the act of gargling. It is commonly practiced to maintain oral hygiene and prevent illnesses, especially during cold and flu seasons. The process involves swishing a liquid, often saltwater or mouthwash, in the throat and then expelling it. This helps to remove bacteria and soothe a sore throat. In Japan, many people perform うがい after brushing their teeth or when they feel a sore throat coming on. It is considered a simple yet effective way to promote health. The practice is often accompanied by washing hands, emphasizing overall cleanliness and wellness.
