1. Protect Your Brain

Protecting the brain from injury, pollution, sleep deprivation, and stress is the first step to optimizing its function. The brain is very soft, while the skull is really hard. Inside the skull there are many sharp bony ridges. Several brain areas are especially vulnerable to trauma, especially the parts involved with memory, learning, and mood stability. In order to be your best it is essential to protect your brain from injury. Wear your seatbelt when you’re in a car, and wear a helmet when you ride a bicycle, motorcycle, or go snowboarding. Make sure children wear helmets. My eleven-year-old knows that if she rides her bicycle without a helmet she’ll be grounded from it for a month. One head injury can ruin a life. Along the same lines, do not let children hit soccer balls with their heads. Soccer balls are heavy. Repeatedly slamming a child’s head against a soccer ball may cause minor repetitive trauma to the brain. At this time there are not enough studies to say heading soccer balls is safe. I encourage my children to play golf, baseball, and tennis, rather than football, soccer, or hockey.

Current brain imaging research has shown that many chemicals are toxic to brain function. Alcohol, drugs of abuse, nicotine, much caffeine, and many medications decrease blood flow to the brain. When blood flow is decreased the brain cannot work efficiently. In one study done at UCLA, cocaine addicts had 23% less overall brain blood flow compared to a drug free control group. Those cocaine addicts who smoked cigarettes had 45% less blood flow than the control group. In a study I performed on chronic marijuana users, 85% had less activity in their temporal lobes than the control group. The temporal lobes are involved with memory and mood stability. Caffeine constricts blood vessels and has been shown to decrease brain activity. A little bit of caffeine probably doesn’t hurt much. Unfortunately, many people use excessive amounts, such as 6 to 10 cups of coffee, tea, or sodas a day. It is hard to be your best when brain activity is diminished. Stay away substances known to be toxic or those that decrease brain activity.

In a similar way, sleep deprivation also decreases brain activity and limits access to learning, memory, and concentration. A recent brain imaging study showed that people who consistently slept less than 7 hours had overall less brain activity. Sleep problems are very common in people who struggle with their thoughts and emotions. Getting enough sleep everyday is essential to brain function.

Scientists have only recently discovered how stress negatively affects brain function. Stress hormones have been shown in animals to be directly toxic to memory centers. Brain cells can die with prolonged stress. Managing stress effectively is essential to good brain function.
