Jeremy HerveWe’ve all seen videos inviting us to sleep more, avoid blue light before bed, avoid coffee… This video goes beyond all that and explains why, in our modern world, we often feel tired.
It attributes much of this to mental fatigue, caused by decision overload. Our brains, originally built for simpler tasks, struggle with the thousands of decisions we make daily. It leads to a buildup of glutamate—a neurotransmitter that clogs neural pathways and makes decision-making harder, causing fatigue. And we make things even worse by drinking coffee! Adenosine is a chemical that naturally signals the brain to rest. It builds up throughout the day but caffeine blocks it, delaying tiredness, and stopping us from going to sleep when we should.
