Stop 4 PM brain fog with these 5 steps | Dr. Arif Khan #productivity #focus

Have you ever wondered why your brain feels broken by 4pm, no matter how well you slept or how much coffee you drank? In 2022, a Paris research team made a striking discovery: prolonged thinking causes a measurable buildup of glutamate in your lateral prefrontal cortex, the part of your brain responsible for focus and self-control. Once this chemical crosses a certain threshold, your brain begins to throttle itself on purpose, slowing you down to protect itself from damage. In this video, Dr. Arif Khan, British Board-certified Consultant Pediatric Neurologist, breaks down the science of cognitive exhaustion, explains why modern life is wearing your brain out faster than at any other point in human history, and shares five neuroscience-backed steps you can start applying today to feel like yourself again.
