Not simply a state of rest, sleep has its own specific, positive functions. Sleep is considered vital to human health and well-being, and is critical to physiological and cognitive functioning. Elite athletes experience high training and competition demands, and are often exposed to various factors, situations, and environments that can cause sleep impairments. The objective of this study is to see the effect of sleep loss and mood on athlete’s performance. Total sample size of 200 has been taken by using the simple random sampling. Three questionnaires have been used for data collection. Firstly sleep-loss questionnaire, secondly mood questionnaire and thirdly self-rating scale to measure athlete’s performance. Data has been collected from athletes of government and private sector universities of Lahore. The Cronbach’s Alpha reliability statistics over all value is 0.767. To find out the relationship between sleep loss and mood and performance the correlation is applied and the result are the sleep loss has the low (𝑟 = −0.161) level correlation and that it is statistically significant (𝑝 = .022) which is negative and significant. The mood has the low (𝑟 = 0.267) level of correlation and that it is statistically significant (𝑝 = .000) which is positive and significant. This study has been conducted on the students of different games. Sleep loss has insignificant (p>0.01) positive impact while mood has significant (p
