How Meditation Helps You Maintain Brain Health IMPROVE COGNITIVE FUNCTION IN MINUTES
Meditation has often been touted by New Age gurus as a way to find inner peace and stillness. But what if meditating could reduce the effects of aging on your brain? According to research, taking a few minutes out of your day to meditate may improve cognitive function. As meditation’s popularity has spread, so have studies of the practice. The results of 100 studies examining the cognitive effects of meditation all show evidence of improvements in psychological and cognitive functions. Some of the results are intuitive, such as how meditation helps us deal with stress. But other results are incontrovertible, such as scans showing that meditation causes structural changes in the brain. For people facing age-related changes like memory loss, the results of these tests are especially relevant. The studies point to evidence that meditation can strengthen certain areas of the brain — the prefrontal cortex, the hippocampus, and the amygdala — that weaken as we age. THE PREFRONTAL CORTEX Your prefrontal cortex thins with age, which is associated with decreased cognitive function in your later years. However, meditation may reduce this age-related thinning. Dr. Sara Lazar, a neuroscientist specializing in
the effects of yoga and meditation on cognitive and behavioral function, reports that long-time meditators don’t show a decline in the thickness of the prefrontal cortex. THE HIPPOCAMPUS Your hippocampus helps you process and form new memories, and it’s very sensitive to stress. In fact, research shows that your hippocampus will shrink in response to stressful situations and chronic stress. The remedy? Meditation. Dr. Lazar’s study showed a positive correlation between meditation and a higher concentration of gray matter in the left hippocampus. THE AMYGDALA Often called the fear center of the brain, the amygdala is triggered by stressful situations. But unlike the hippocampus, which shrinks in response to stress, the amygdala has been shown to become denser. In one study, people who attended mindfulness meditation classes showed a smaller stress response in brain scans compared to those who did not attend the classes. Meditation may help to decrease the density of the amygdala and therefore increase your ability to handle stress.
HOW MUCH SUNSHINE IS TOO MUCH?
Keep Your Family Safe
your own? What’s the best way to step out of the sun for a few minutes? Wearing sunscreen and protective clothing are great ways to shield yourself from UV rays, but it’s important to avoid being in direct sunlight for long periods. Taking a break from the sun gives your body the time it needs to recuperate and helps prevent sunburn and heatstroke. COMMON MYTHS ABOUT SUN EXPOSURE Many people think that a tan is better than a sunburn, but the result of tanning is still sun damage. When your skin tone changes due to the sun, regardless of whether it tans or turns red, it’s a result of the epidermis reacting to damage caused by UV rays. Both are symptoms of harmed skin. While vitamin D is important, the sun does not contribute to its creation as much as you might think. Doris Day, a New York City dermatologist, explains that if your skin were to constantly produce vitamin D from being in the sun, it would reach toxic levels. Vitamin D is the only vitamin that your body can produce on its own, through a common form of cholesterol or 7-dehydrocholesterol. Spending time in the sun does help vitamin D form, but you need far less exposure than you think.
To many people, summer is all about heading outside to enjoy the weather. But getting too much sun can be dangerous. To have a fun-filled summer with your family this year, remember that it’s essential to protect yourself from harmful UV rays. COVER UP Covering your skin is one of the best ways to avoid skin damage. Wide- brimmed hats, long-sleeved shirts, and long pants or skirts can protect your skin from direct exposure to UV rays. While this tactic protects you from the sun, it offers poor defense against the heat. So, if you opt for cooler attire, it’s important to cover all exposed skin with a copious amount of sunscreen. Be sure to reapply every two hours for maximum skin protection. SPEND LESS TIME IN THE SUN If you’re planning to spend a significant amount of time in the sun, consider your environment. Will there be plenty of shade? Will you have to bring
Knowing how to protect yourself from UV rays is the first step to having a safe, fun-filled summer!
