What anxiety actually is
Anxiety is your body's fear and threat response, a feeling of nervousness, worry or unease that can show up as a racing heart, restlessness, muscle tension, trouble sleeping or trouble concentrating. Some anxiety is a completely normal part of being human, it's what your body does before a hard conversation or a big deadline.
It becomes an anxiety disorder when it doesn't go away and starts interfering with daily life, something roughly a third of adults experience at some point, according to the US National Institute of Mental Health. Here in South Africa, the national SASH study, the largest population survey of its kind, found anxiety disorders are the single most common category of mental health condition in the country, ahead of mood disorders and substance-use disorders.
