You've probably heard that too much caffeine can cause jitters and sleeplessness. But could it also cause brain fog?
Some experts say yes. Caffeine can overstimulate the central nervous system, which can lead to problems with focus and concentration. It can also interfere with sleep, which is critical for optimal brain function.
If you're experiencing brain fog, it might be worth cutting back on caffeine or avoiding it altogether. Consider drinking decaf coffee or tea, or using a natural nootropic supplement like Brain Fog Buster to help you stay focused and energetic.
