How does a lack of sleep affect the brain?
Sleep deprivation makes us moody and irritable, and impairs brain functions such as memory and decision-making. It also negatively impacts the rest of the body – it impairs the functioning of the immune system, for example, making us more susceptible to infection.

Is 5 hours enough for sleep?

Which is worse too much sleep or not enough?
