Sleep has a major impact on reaction time. Lack of sleep slows down brain function, making it harder to process information quickly. Even a single night of poor sleep can significantly increase reaction time. On the other hand, proper rest improves alertness, focus, and response speed. Athletes and gamers often prioritize sleep to maintain peak performance. If you notice slower reaction times, improving your sleep schedule can make a big difference. Aim for 7 to 8 hours of quality sleep to ensure optimal cognitive and physical performance.
