Caffeine is probably the most commonly used chemical stimulant. More than 90% of Americans consume caffeine on a daily basis in their coffee, soda, tea, or chocolate. Pure caffeine is a white bitter-tasting powder that can be extracted from coffee, tea, the guarana berry, or from other sources.
Caffeine is a brain stimulant. It works in the brain by blocking the natural effect of adenosine on the nerve cells, causing increased mental activity. It also causes the body to release adrenaline, which causes the heart to beat faster, blood pressure to rise, muscles to tighten up, and extra sugar to be released into the bloodstream for a burst of energy. This is why it is often used to counteract sleepiness.
Caffeine is an addictive substance. When the effects from caffeine wear off, the feelings of fatigue, depression, and irritability set in. Taking more caffeine can counteract these feelings, but this leads to a dangerous cycle. With prolonged use, it can interfere with the brain's ability to reach deep sleep and become fully rested, which means that the person will feel tired in the morning and be more inclined to take even more caffeine.

"I had been more than half suspicious of the seeming sincerity of the Kaolian jeddak's sudden apostasy, but the alacrity with which he embraced my suggestion, and the despatch with which a force of officers and men were placed at my disposal entirely removed the last vestige of my doubts." --Burroughs, Edgar Rice
Free radicals are molecules that are naturally produced by the body during normal functioning. Free radicals are highly reactive and thus are likely to take part in a chemical reaction. In the body these reactions tend to be destructive, and over time can contribute to various problems, including memory decline. Antioxidants are chemicals that can neutralize these free radicals and thus prevent them from initiating any harmful reactions.

Vitamin C: Found in citrus and green leafy vegetables.
Vitamin E: Found in nuts, seeds, whole grains and green leafy vegetables.
Bio-flavonoids: Found in berries and green tea.
In one study, vitamin E was shown to help prevent normal age related memory decline. In another study vitamins C and E showed some promise in helping patients with dementia. Many other studies have shown additional health benefits from eating antioxidants. So, eat your vegetables!
Chronic stress can cause an imbalance in the neurochemicals that contribute to elevating our mood and reducing anxiety. Fortunately, research has shown that you can reduce the imbalance simply by smiling or laughing, regardless of your actually mood. When you smile or laugh, your brain gets fooled into thinking that it is happy, and releases the corresponding neurochemicals. Laughter has been shown to have the following benefits.
1. Lowering levels of the stress hormone, cortisol
2. Reducing blood pressure
3. Boosting the immune system
4. Improving respiration and circulation
5. Reducing pain
6. Reducing depression and improving mood
If you are having a hard time getting motivated to do something and you need a pick me up, try smiling or laughing out loud. It may sound silly, but it can actually improve your mood and get you thinking more creatively. So, when life gives you a frown, turn it upside down!
