Anxiety is a normal human response to stress, uncertainty or perceived threat. In short bursts, it can be helpful. It sharpens focus before an interview, increases alertness in a risky situation or motivates preparation for an important event. Fact is, if we didn’t feel some level of anxiety, we probably wouldn’t get out of bed in the morning.
However, when anxiety becomes persistent, overwhelming or disproportionate, it can begin to interfere with daily life.
Understanding the signs of anxiety is important because many people experience symptoms without realising that anxiety may be the cause. Contrary to common misunderstanding, anxiety doesn’t just affect the mind. It can impact both the body and behaviour.
The causes and symptoms often vary from person to person. This makes it difficult to identify triggers and to know if that disconcerting feeling is anxiety.
In this article, we explore the common signs of anxiety, possible causes, treatment options and when it may be helpful to seek professional support.
What is anxiety?
Anxiety is the body and mind’s response to perceived danger. It is closely linked to the nervous system and the fight, flight or freeze response. When the brain detects a threat, stress hormones such as adrenaline and cortisol are released, preparing the body to respond.
This reaction can be useful in genuinely dangerous situations – such as when we’re required to perform an emergency manoeuvre on the motorway. In such scenarios, the flood of emotion triggered by the threatening event is gone almost as quickly as it came. Very soon, we're back to our normal selves.
Problems arise when the alarm system activates too often, too intensely or without a clear external threat – worrying what people think of you. Instead of a flash flood of emotion, cortisol and other stress hormones are being drip fed into our system. Thus the 'anxious feeling' never really abates, it's always there, perculating under the surface.
For some people, anxiety becomes chronic and exhausting. Generalised Anxiety Disorder, Panic Disorder and Social Anxiety Disorder are examples of anxiety-related conditions.
Common signs of anxiety
The signs of anxiety can be grouped into four distinct categories: 1) emotional, 2) physical, 3) cognitive and 4) behavioural. Under each of these categories, commonly reported signs of anxiety have been listed.
Concluding the lists, a printable anxiety tracker document has been included. The purpose of this document is to enable you to track the frequency and grade the intensity of your anxiety symptoms.
This can be helpful because it makes the invisible visible. The signs of anxiety can be subtle and thus slip under the conscious radar, so to speak. But for many, even mild anxiety is disquieting and debilitating. By exposing it, you’ll be in control and thus able to take active steps to tackle the triggers while managing the symptoms. As P. F Drucker said:
'What gets monitored gets managed,' (Manging Oneself).
Emotional signs of anxiety
Many people first notice anxiety through how they feel emotionally. Common emotional signs include:
Persistent worry
Feeling on edge
Irritability
Restlessness
A sense of dread
Feeling overwhelmed
Difficulty relaxing
Fear that something bad will happen
These feelings may come and go, or they may feel present most days.
Physical signs of anxiety
As Bessel van der Kolk observes in his book, The Body Keeps the Score, signs of anxiety (historic trauma and other mental health conditions) often show up in the body. Because the nervous system is activated, physical symptoms can feel intense and sometimes frightening.
Common physical signs of anxiety include
Racing heart or palpitations
Sweating
Shaking or trembling
Tight chest
Shortness of breath
Dizziness
Nausea
Headaches
Muscle tension
Fatigue
Stomach discomfort
Tingling sensations
Some people worry these symptoms mean there is a serious physical illness. While medical causes should always be ruled out when symptoms are new or severe, anxiety can strongly mimic physical health problems. The NHS notes that anxiety can create both psychological and physical symptoms.
Cognitive signs of anxiety
Cognitive symptoms relate to thinking patterns. Anxiety can influence attention, memory and perception.
Common cognitive signs include
Overthinking
Difficulty concentrating
Racing thoughts
Catastrophising
Constant “what if” thinking
Trouble making decisions
Feeling mentally overwhelmed
Expecting the worst
When the mind is focused on threat, it becomes harder to think clearly or stay present.
Behavioural signs of anxiety
Anxiety can also change behaviour, often in ways designed to reduce discomfort in the short term.
Common behavioural signs include
Avoiding certain places or situations
Reassurance seeking
Procrastination
Social withdrawal
Checking behaviours
Overpreparing
Difficulty speaking in groups
Trouble leaving the house
Increased use of alcohol or other coping habits
Although these behaviours may bring temporary relief, they can reinforce anxiety over time.
What causes anxiety?
Now that we’ve familiarised ourselves with the signs of anxiety, the next essential step is to understand the causes. This is important because managing the symptoms alone will never result in the eradication of anxiety. But being able to identify and remove the triggers will enable you to tackle the problem at its root.
There is rarely one single cause. Anxiety usually develops through a combination of biological, psychological and environmental factors.
Genetics and biology: Some people may be more predisposed to anxiety because of temperament, family history or nervous system sensitivity.
Stressful life events: Work pressure, relationship difficulties, grief, financial stress or historic trauma (adverse childhood experiences) can trigger or worsen anxiety symptoms.
Learned patterns: Past experiences can teach the brain to anticipate danger, even in relatively safe situations.
Health and lifestyle factors: Poor sleep, excessive caffeine, alcohol misuse, chronic stress and certain health conditions can all contribute to anxiety.
When anxiety becomes a problem
As we acknowledged in the introduction, occasional anxiety is part of life. Without it, we would lake the drive to take on big tasks and prepare for important events. In saying that, though, anxiety may become problematic when:
Symptoms persist for weeks or months
Daily functioning is affected
Sleep is regularly disrupted
Relationships suffer
Work or study becomes harder
Avoidance is increasing
Panic attacks occur
You feel unable to cope
The intensity of symptoms matter, of course, but arguably less so than the impact they have on your life. A person who struggles with severe anxiety prior to that once-a-year conference is less affected than the person who experiences mild symptoms every time they are in a social setting.
Panic attacks and severe anxiety
Some people experience panic attacks, which are sudden episodes of intense fear accompanied by physical symptoms such as rapid heartbeat, dizziness, chest tightness and a sense of losing control.
Panic attacks can feel alarming, but they are treatable – usually with simple techniques such as grounding exercises and mindfulness breathing. Many people benefit from understanding what is happening physiologically and learning strategies to regulate the nervous system.
How anxiety is treated
Anxiety is highly treatable, and support can be tailored to individual needs. In most cases, mild anxiety symptoms are self-managed. For example, people who suffer uncomfortable physiological responses to social situations may quell the symptoms with mindfulness meditation.
However, chronic and/or prolonged anxiety may require therapeutic intervention. Below, we explore a range of some of the most effective methods for treating severe anxiety.
Cognitive Behavioural Therapy (CBT)
National Institute for Health and Care Excellence recommends therapies such as Cognitive Behavioural Therapy (CBT) for many anxiety presentations. CBT helps identify unhelpful thought patterns and behavioural cycles that maintain anxiety.
Mindfulness and acceptance approaches
Mindfulness-based approaches help people notice anxious thoughts without becoming overwhelmed by them. In addition, because of its ‘non-judgemental’ ethos, it also helps to attenuate self-criticising voices. Another strength of mindfulness is its broad range of techniques and exercises – diaphragmic breathing, choiceless awareness, body scanning, to name a few. The multifaceted nature of mindfulness makes it eminently tailorable to personal preferences.
Somatic and nervous system regulation approaches
Breathing exercises, somatic grounding, progressive muscle relaxation and body-based approaches can help regulate physiological arousal. Studies have shown that such strategies disrupt the cycle of negative rumination that fans the flames of anxiety.
Lifestyle changes
Scores of studies demonstrate that improving sleep, reducing caffeine and alcohol consumption, exercising regularly, creating healthy routines and eating wholesome, fresh foods can support recovery. In addition to promoting general health and vitality, making these lifestyle changes confer positive psychological outcomes as well. How? Well, when we’re looking after our body, it makes us feel good.
Medication
If after trialling the above methods anxiety symptoms persist, pharmacological interventions maybe required. When considering the course, it is imperative first to speak to a qualified medical professional. They will provide an assessment prior to prescribing suitable medication.
Practical self-help strategies for anxiety
Many of the methods for managing the signs of anxiety outlined above do not deliver instant results. They take time and consistent application before a noticeable attenuation of the severity of anxiety symptoms occur.
Though they certainly have their place in the treatment process, those who are struggling now need strategies that help in the moment.
If you are noticing signs of anxiety, the following seven strategies may help:
Name what is happening – recognising anxiety can reduce fear of symptoms.
Slow your breathing – longer exhales can calm the nervous system.
Limit stimulants – caffeine can worsen symptoms for some people.
Reduce avoidance gradually – small steps build confidence.
Challenge catastrophic thinking – ask what evidence supports the fear.
Stay connected – speak with trusted people.
Seek support early – anxiety often responds well to treatment.
When to seek professional help
In some cases, a sufferer of anxiety will need to seek professional support. The problem is, because of the (largely perceived) social stigma surrounding anxiety, coupled with our (real) reluctance to reach out, many do not access the help that they desperately need.
These two barriers contribute to a lot of needless suffering. Sad as it is, some people would rather endure the debilitating effects of daily panic attacks than face the (imagined) scrutiny of contacting a trained therapist or speaking to their GP.
To overcome anxiety and reclaim control of our lives, it’s imperative to breakthrough these barriers.
But when is it time to seek support? Below is a list of situations that suggest a person needs to speak with a trained professional.
Consider professional support if
Anxiety feels unmanageable
Symptoms are frequent or intense
Panic attacks are occurring
You are avoiding more of life
Work, relationships or sleep are affected
Self-help strategies are not enough
A GP, counsellor, psychologist or mental health professional can help assess what is happening and recommend appropriate treatment.
Reducing stigma around anxiety
Many people feel embarrassed about anxiety, particularly when symptoms are invisible. Yet anxiety is common and treatable. Seeking support is a practical step, not a sign of weakness.
Open conversations, education and compassionate workplaces that prioritise mental health can all help reduce stigma and encourage early intervention.
Final thoughts
The signs of anxiety can appear in many forms: racing thoughts, muscle tension, dread, avoidance, fatigue or difficulty concentrating. Some symptoms are obvious, while others are subtle. The key is noticing patterns and recognising when anxiety is affecting quality of life.
With the right support, anxiety can become far more manageable. Whether through therapy, lifestyle changes, self-help strategies or professional treatment, recovery is possible.
