Q: I've been trying not to drink coffee in the afternoon, but I need some type of pick-me-up. Is there a snack I can eat that will give me a boost?
A: Believe it or not, it's completely normal to feel a bit sleepy in the afternoon due to the natural hormonal and temperature changes regulated by our circadian rhythm, also known as our biological clock.
For a quick pick-me-up that isn't loaded with caffeine, focus on increasing fluids. Try gulping a large glass of cool water or seltzer with a splash of cranberry or mango juice. If you prefer a hot beverage, a cup of green or herbal tea will also do -- however, test yourself to see if hot or cold beverages work better for pepping you up.
Fruits and vegetables are also a natural source of fluid and can provide energizing vitamin C. Grab a handful of grapes or a medium sized orange.
Sometimes we need energy from food, but try not to load up on high-sugar items as they raise blood sugar quickly. Keep on hand an emergency snack of trail mix made with dried fruit and nuts. Nuts and fruit provide a balance of carbohydrates, fat and protein, which helps give us a boost without a drastic crash in blood sugar afterwards.
