The Impact of Sleep Deprivation on Cognitive Functioning and Emotional Well-Being

Sleep is a vital biological process essential for maintaining both cognitive functioning and emotional well-being. We already know that not sleeping enough messes with our brain, making it hard to focus, slowing down our reactions, and making us more likely to overreact emotionally. Big health organizations like the World Health Organization and the Indian Council of Medical Research say that not sleeping enough is a serious health problem, and they emphasize how important good sleep is for our overall health. Existing research shows that lack of sleep impairs brain functions, leading to poor concentration, slower reaction times, and heightened emotional responses. Health organizations like the World Health Organization (WHO) and the Indian Council of Medical Research (ICMR) have recognized sleep deprivation as a public health issue, stressing the importance of proper sleep for overall well-being. Despite growing awareness, there remains a gap in understanding the combined impact of sleep deprivation on cognitive and emotional health, especially in the Indian context. This paper aims to bridge that gap by reviewing existing literature and emphasizing the need for promoting better sleep hygiene and mental health practices.
