202 What Coffee Does to Your Health Coffee can be considered one of nature's greatest gifts. It gives mental and emotional clarity without harmful side effects, (like alcohol or tobacco), and it contains a wealth of nutrients. Yet, when most people drink coffee, they are not thinking that the beverage is improving their health. In fact, some may even feel a little guilty, since they believe coffee isn't good for you at all. Well, here's the truth of the matter. Coffee, like anything else, can cause problems if too much is consumed (taken). In the short-term, too much coffee will cause insomnia, nausea and hypertension. In the long-term, too much coffee will cause stomach problems, teeth staining, and high cholesterol. As for the benefits, moderate consumption of coffee, (which means 1 to 4 cups a day), supplies your body with a wealth of antioxidants. These substances are responsible for eliminating free radicals. They are the chemical byproducts produced any time your body does something. A small number of them can help serve as a buffer against negative elements, but if they aren't kept in check, they can cause health problems. Antioxidants ensure that this doesn't happen. The psychological effects of caffeine cannot be ignored either. Not only does caffeine make you more alert, but it can actually affect your mood. If you were feeling depressed or overwhelmed, a nice cup of coffee could change your perspective. The stack of work that seemed impossible before isn't even a problem now. In addition, caffeine helps stimulate creativity as it speeds up the body's functioning. That's why coffee is often associated with writers and other intellectual professions. Other drugs tend to make people dumber. Consider what happens when people get high off of crack or when they get drunk off of alcohol. They won't be functional at all. But with coffee, an individual gets a creative boost while still helping their bodies. In conclusion, don't feel bad when you're brewing your morning cup of coffee. Unlike a can of soda or a shot of alcohol, coffee will make you feel wonderful while keeping you healthy. Just remember, you do have to consume the beverage in moderation.
78 203Brain Actions Researchers in Europe and the US wanted to find out exactly what happens to our brain when we find ourselves stunned with fright in the hope of better understanding how fear interplays with human anxiety disorders. For the first time, they traced and linked three parts of the brain responsible for freezing behaviors: the amygdala, ventrolateral periaqueductal grey region and magnocellular nucleus. Mice are excellent lab animals where it comes to anxiety and fear experiments. When a mouse is scared, its defensive behaviors range from freezing, attacking, risk assessment or fleeing the scene. How a mouse acts depends on variables such as access to escape routes or the level of threat faced.
