Drowsiness is a condition where a person feels like sleeping. This can happen at the wrong time, for example when working, while studying, or when driving. Sleepiness is usually characterized by fatigue, loss of consciousness, sleep, and can interfere with activity. Drowsiness generally occurs due to lack of sleep. Everyone has different sleeping needs, depending on age and daily activities. Ideally, adults need 7-9 hours of sleep per day, children up to teenagers need 9 hours, toddlers take 10-12 hours, and newborns take 16-18 hours. Although it looks simple, sleepiness can lead to problems, such as interrupting performance and productivity at school, college, or office, affecting one's emotions, interfering with social interaction, and the most fatal is that it can cause accidents on both the road and workplace.
