A short YouTube monologue by Joy Kong, MD arguing that serotonin buildup during exercise contributes to fatigue and limits the ability to keep pushing. The speaker references Dr. Andrew Huberman and states a personal preference to avoid deliberately increasing serotonin because it can blunt dopamine, leading to reduced motivation, apathy, and anhedonia.
Did you know that when you exercise, the reason why people feel fatigued and they can't keep pushing harder is because serotonin levels have built up? Serotonin can contribute to fatigue during exercise. I was actually listening to Dr. Andrew Huberman talk about serotonin this morning on a podcast. He doesn't deliberately want to increase serotonin, and I'm the same. I personally don't want to increase serotonin on purpose. Why? Because serotonin, for me, actually blocks and blunts the effects of dopamine. Basically can make you feel like anhedonic, apathetic, like you're not actually motivated. It actually makes you want to just chill. This is a well known fact of why some people can keep pushing and others are like, nah, I can't be bothered. You know, like, I just can't.
