Effects of sleep deprivation on cognitive performance

Sleep deprivation means you don't get enough sleep. This can have a big impact on your cognitive performance, which is how well you think and do things like remember information. When you don't get enough sleep, it can make it harder to learn or pay attention. It also makes you more forgetful and unable to concentrate on things. Your reaction time can be slower too, so it can be harder to react quickly to things.
