Why do blueberries keep me awake?

Blueberries contain natural sugars and carbohydrates that can provide a quick source of energy, potentially contributing to wakefulness. Additionally, they are rich in antioxidants and vitamins that may stimulate brain function and enhance cognitive performance. The presence of certain compounds, such as caffeine or other stimulants in combination with your overall diet, could also influence your alertness. If you're experiencing difficulty sleeping after consuming blueberries, consider the timing and portion size.
