It's National Caffeine Month Too
It's quite likely that your student is consuming quite a bit of caffeine. This month also provides the perfect opportunity to share some health tips about this interesting drug:

• Higher doses of caffeine can cause anxiety, dizziness, headaches and the jitters. Caffeine can also interfere with normal sleep patterns.
  
• Caffeine is a diuretic, meaning it causes a person to urinate more. The verdict isn't out yet on whether or not this causes dehydration.
  
• Caffeine may also cause the body to lose calcium, and that can lead to bone loss over time.
  
• Caffeine can aggravate certain heart problems.
