Our old friends, stress, anxiety and plain old exhaustion contribute to your morning brain fog. And you are probably thinking, a cup of Joe can help dissipate that fog hanging over you. But have you ever wondered if that morning cup of caffeine has any benefits?

Though there’s no solid evidence that caffeinated beverages will help you remember where you last left your car keys, briefcase, or children, for that matter, part of what makes you smart can retrieve the information you’ve learned in the past.

However, stress, anxiety, information overload and plain old exhaustion can contribute to your morning brain clouds, making you feel less than sharp. That’s where caffeine comes in.

As a stimulant, caffeine can make you feel more alert. If you’re more alert, you’re better able to process information, but too much caffeine can create jitteriness, making it more difficult to focus and process information.

Bummer, just when you thought you found an easy way to boost your intelligence.

So how do you strike a balance? Getting enough sleep and reducing your stress level can help. Try focusing on the tasks at hand during your workday, avoid phone calls, if you can, to roll to voice mail and try not to check your e-mail as often.

It is all easier said than done, but I must say it does work. I have gotten myself down to two cups of coffee a day; reducing my intake of Pepsi is another story.

Another health note for coffee drinkers: stick to filters. A new study suggests that coffee brewed without filters may increase your risk of a heart attack or stroke.

Unfiltered coffee contains diterpenes, and chemicals are known to increase the amount of homocysteine in the bloodstream (homocysteine has long been suspected to increase the risk of heart problems).

When you use coffee filters, they remove these diterpenes, thus lowering your risk of homocysteine.

So use that boost of intelligence you get from coffee and use your filters. Use your French Press to hold flowers or your coffee filters.
