Weegy: Anxiety is a natural human reaction that involves mind and body. [ It serves an important basic survival function: Anxiety is an alarm system that is activated whenever a person perceives danger or threat. When the body and mind react to danger or threat, a person feels physical sensations of anxiety — things like a faster heartbeat and breathing, tense muscles, sweaty palms, a queasy stomach, and trembling hands or legs. These sensations are part of the body's fight-flight response. They are caused by a rush of adrenaline and other chemicals that prepare the body to make a quick getaway from danger. They can be mild or extreme. It's completely normal to worry when things get hectic and complicated. But if worries become overwhelming, you may feel that they're running your life. If you spend an excessive amount of time feeling worried or nervous, or you have difficulty sleeping because of your anxiety, pay attention to your thoughts and feelings. They may be symptoms of an anxiety problem or disorder. for more information and source: kidshealth.org › Teens › Your Mind ] (More)
