What's happening in your body and brain when you're homesick

Huff Post quotes Daniel Rifkin in an article reporting what happens to your body and mind when you feel homesick. Rifkin states the symptoms related with homesickness are similar to what people experience when they are grieving or dealing with an unimaginable loss. Rifkin explains this is due to abnormal distress signals originating in the deepest parts of your brain. “From there, through your sympathetic nervous system, your adrenal gland is triggered to release abundant amounts of adrenaline. Usually, you have your parasympathetic nervous system to offset those abnormal signals, but in heightened states of anxiety or stress, your parasympathetic system is no match,” Rifkin says.
