At 3.6 million square miles (9.4 million square kilometers), the Sahara, which is Arabic for The Great Desert, engulfs most of North Africa. The desert covers large sections of Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Western Sahara, Sudan and Tunisia.This is the image many people have of the Sahara: a vast sea of sand dunes.The terrain is actually quite varied.alf of the Sahara receives less than an inch of rain per year, and the rest receives up to 4 inches (10 centimeters) per year. The infrequent rain is usually torrential. The highest peak in the Sahara is the volcano Emi Koussi (11,204 feet or 3,415 meters) in the Tibesti Mountains in northern Chad.
Is Depression All in the Stomach? Pierre Pallardy, the French alternative therapist, is certain that the roots of depression lie in the stomach. In his 2007 book Gut Instinct: What Your Stomach Is Trying to Tell You, he outlines his belief in the power of the stomach to cause or cure a wide range of physical and mental ailments.
Dr. Randi Fredricks, Ph.D. is a therapist, researcher and author with a Ph.D. in Psychology and a Doctorate in Naturopathy. It turns out that stomach problems can cause a lot more than just physical discomfort. Research has suggested that gastrointestinal troubles may be linked with anxiety and depression as well. It is probably no surprise that stomach issues can cause stress, but they can also lead to significant mental health problems. The stomach complaints most strongly associated with anxiety and depression appear to be conditions such as irritable bowel syndrome (IBS). However, a 2011 Stanford University study discovered that even short-term digestive problems can lead to mental health issues later.
