Anxiety symptoms: in your mind and in your body

Anxiety is a whole-body state, not just worried thoughts. It is the nervous system stuck in "threat mode" when there is no threat — which is why it produces such convincing physical symptoms that many people first suspect a heart or stomach problem.

The symptoms below span the mental and the physical. Generalized anxiety is marked by worry that is excessive, hard to control, and present more days than not for six months or more. If this sounds familiar, the GAD-7 anxiety screening gives you a quick, private read.

The symptoms, one by one

Uncontrollable worry

Your mind jumps from one "what if" to the next, and telling yourself to stop doesn't work. The worry often outsizes the actual risk, and lands on everyday things — health, money, work, loved ones.

Feeling on edge or restless

A background hum of tension, as if waiting for bad news. Sitting still can feel impossible; some people pace, fidget, or feel a need to keep busy.

Physical tension and aches

Clenched jaw, tight shoulders, headaches, and a knotted stomach are anxiety showing up in muscle. Chronic tension is exhausting in its own right.

Racing heart and shortness of breath

The body's alarm system firing: a pounding or fluttering heart, tight chest, or the sense you can't get a full breath. Alarming, but not dangerous in itself.

Digestive upset

The gut is deeply wired to anxiety. Nausea, cramping, or urgent trips to the bathroom before stressful events are common and real.

Trouble concentrating

Worry hijacks working memory, so focus and recall suffer. People often fear this means something is wrong with their brain — it's the anxiety using up the bandwidth.

Sleep disruption

A racing mind at bedtime, or waking at 3am unable to switch off. Poor sleep then feeds more anxiety the next day — a loop worth breaking.

Irritability and dread

Being quicker to snap, and a persistent sense that something awful is about to happen even when nothing is wrong.

How it varies

• Panic attacks are anxiety at full volume: sudden, intense physical surges that peak within minutes.
• Social anxiety centers on fear of judgment in social or performance situations.
• In children and teens, anxiety often shows as physical complaints or refusal to go to school.
• Anxiety and depression frequently travel together, which is why our screens are worth taking as a pair.
