Can you get brain damage from lack of sleep?
At a more advanced level, sleep deprivation can over-stimulate parts of the brain and even lead to permanent brain damage, according to a report on sleep deprivation among students published by The Guardian. “This is because of the brain’s ‘neural plasticity’ – which means its ability to adapt to new situations.
