Need to remember something important today? Have a little caffeine.
A new study finds whether it is coffee, tea, or even soda, caffeine can improve your long-term memory.
At this point, researchers don't know how or why this happens but they think caffeine somehow helps the hormones that are related to making new memories.
But moderation may be key.
Experts warn, drinking too much caffeine or highly caffeinated products like energy drinks can lead to sleep problems.
