Health Fact: Your Brain Uses 20% of Your Body’s Energy

Post
Health Fact #47:
Your brain is only ∼2% of your body weight… but it uses about 20% of your daily energy.

That’s why skipping meals, poor sleep, or dehydration makes you feel “foggy” and slow. Your brain runs mainly on glucose + oxygen.

3 simple ways to fuel your brain daily:

1. Hydrate: Even 2% dehydration = lower focus + headaches. Water > energy drink.
2. Eat smart carbs: Oats, beans, plantain, sweet potato give steady glucose. Sugar spikes = crash later.
3. Sleep 7-8hrs: Memory + decision-making get “saved” while you sleep. All-nighters hurt more than they help.

Bottom Line:
If your brain feels tired, check water + sleep + food first before coffee.

Important: This is general health information, not medical advice. For persistent fatigue, headaches, or memory issues, speak with a doctor, nurse, or pharmacist.
