Scientists have discovered that lack of sleep doesn’t just make you drowsy—it can cause your brain to start eating away at itself. When you go without proper rest for too long, certain brain cells become overactive.
They begin breaking down the tiny connections called synapses, which are responsible for communication between neurons.
This self-damage, sometimes called “cellular cannibalism,” can affect memory, focus, and even speed up brain ageing. Missing one night of sleep may not harm you permanently, but constant deprivation can have serious effects.
Getting enough deep, regular sleep isn’t just about energy—it’s essential for protecting brain health and long-term mental sharpness.
