An In-depth Examination of Anxiety: Causes, Symptoms, and Treatments

Shining a light on this common yet often misunderstood mental health experience can help reduce stigma, encourage those suffering to seek help, and equip everyone with a deeper understanding of anxiety's impact.

What is Anxiety?

Anxiety is an emotion characterised by feelings of tension, worried thoughts, and physical changes like increased blood pressure. It is extremely common, with around 40 million American adults suffering from an anxiety disorder in any given year. While anxiety is a normal human response, some people experience excessive, persistent anxiety that can interfere with daily life.

The Difference Between Normal and Clinical Anxiety

Mild anxiety in response to stressful life events is normal and often helpful. Clinical anxiety disorders like generalized anxiety disorder (GAD), panic disorder, and social anxiety disorder involve more severe symptoms that persist for at least 6 months and impede normal functioning. People with anxiety disorders frequently have intrusive thoughts, avoid situations that cause distress, and experience physical symptoms like heart palpitations and trembling.

How Anxiety Manifests

Anxiety can manifest in different ways depending on the individual. For example, someone with social anxiety may avoid parties and speaking in public, while someone with panic disorder may experience sudden panic attacks with heart racing and difficulty breathing. Factors like genetics, brain chemistry, trauma, and stress influence how anxiety presents.

While anxiety is common, clinical anxiety disorders severely impact quality of life. Recognizing the nuances in anxiety disorders is key for diagnosis and treatment.

Causes of Anxiety

Anxiety disorders can stem from a complex interplay of biological, psychological, and environmental factors. Understanding the root causes of anxiety is key to effective prevention and treatment.

Genetics and Brain Chemistry

Research suggests that genetics account for around 30-40% of individual differences in anxiety. Having a close family member with an anxiety disorder increases your risk. Specific genes influence neurotransmitters like serotonin and norepinephrine, which regulate mood and stress response. Imbalances in these chemicals are linked to anxiety disorders.

Stress and Trauma

Stressful or traumatic life events can trigger anxiety disorders. Things like childhood trauma, grief, financial troubles, or relationship issues can overload our coping abilities. High levels of stress hormones like cortisol disrupt brain circuits involved in managing emotions and reactions to perceived threats.

Environmental Triggers

Environmental factors like pollution, noise, overcrowding, and even low-grade infections may contribute to anxiety. Things like poor diet, lack of exercise, and substance abuse can also play a role. Exposure to stress and adversity in childhood is a particularly strong predictor of anxiety disorders later in life.

Neurotransmitter Imbalances

Neurotransmitters like serotonin, dopamine, and GABA help regulate mood, fear response, and cognition. Low serotonin is linked to increased anxiety and depressed mood. Excess glutamate can cause overstimulation. Low GABA fails to inhibit brain and nerve cell overactivity. Correcting these chemical imbalances with medications or supplements may help relieve anxiety symptoms.

The development of clinical anxiety is complex, with genetic, environmental, trauma-related, and neurochemical factors all potentially playing a role. Understanding these diverse causes is important for developing personalized and effective treatment approaches.

Symptoms of Anxiety

Anxiety can produce a wide range of physical, cognitive, and emotional symptoms that can significantly impact daily life. Recognizing these symptoms is crucial for seeking early intervention and treatment.

Physical Symptoms

Some common physical symptoms of anxiety include:

  • Racing heart rate
  • Shortness of breath
  • Dizziness or lightheadedness
  • Muscle tension and aches
  • Headaches
  • Fatigue
  • Nausea or stomach aches
  • Sweating and chills

Cognitive Symptoms

Anxiety can also produce several cognitive or mental symptoms, such as:

  • Difficulty concentrating
  • Impaired memory
  • Racing thoughts
  • Difficulty making decisions
  • Worrying and rumination
  • Feeling restless or on edge
  • Irritability

Emotional Symptoms

Some common emotional signs of anxiety include:

  • Feelings of panic, fear, and uneasiness
  • Feeling tense or nervous
  • Sense of impending danger
  • Feeling overwhelmed
  • Avoidance of situations or places
  • Difficulty controlling worry
  • Insomnia

If anxiety is significantly impacting daily activities and quality of life, it is important to seek professional treatment and support. Recognizing symptoms early on can lead to more effective management.

Understanding Anxiety Treatments

When it comes to treating anxiety, there are several effective options to consider. Medication, therapy, and self-help strategies all play an important role in managing anxiety disorders. Understanding the benefits and limitations of each approach is key to finding the right treatment plan.



Prescription medications are commonly used to treat anxiety. Antidepressants such as selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) are first-line medications. They can help regulate brain chemistry and neurotransmitter imbalances that contribute to anxiety. Medications begin working in 4-6 weeks and must be taken regularly. While effective for many, some experience side effects like insomnia, headaches, and sexual dysfunction.

Cognitive behavioural therapy (CBT) is an evidence-based form of talk therapy that helps identify unhealthy thought and behavior patterns contributing to anxiety. CBT teaches coping skills, relaxation techniques, and challenging irrational fears. Therapy works to get to the root of anxiety triggers. It takes time but can provide long-lasting benefits. Group therapy offers additional support. Overall, therapy is very effective but requires time, effort, and financial investment.

Self-Help Strategies

Many simple self-help strategies can aid in coping with anxiety. Relaxation techniques like deep breathing, meditation, yoga, and mindfulness can reduce symptoms. Exercise boosts mood and relieves tension. Maintaining healthy sleep, diet, and social support also helps manage anxiety. While useful additions, self-help strategies work best alongside professional treatment. They may not fully address severe clinical anxiety.

The most effective approach is often a combination of medication, therapy, and self-help. It is important to work with a mental health professional to develop an individualized treatment plan catered to your needs and symptoms. Be patient, as finding the right treatment takes time. Seeking help is a courageous first step in reclaiming mental health.

Coping Strategies for Anxiety

Anxiety can feel overwhelming, but there are many effective coping strategies that can help manage symptoms. Making lifestyle changes, learning relaxation techniques, and seeking support can go a long way in reducing anxiety.

Relaxation Techniques

Practicing relaxation techniques is one of the most useful ways to cope with anxiety. Deep breathing, progressive muscle relaxation, and meditation can activate the body's relaxation response and lower stress hormones. Dedicate at least 10-20 minutes per day to practice these techniques. Apps like Calm and Headspace provide guided meditations that can help train your mind to remain calm and focused.

Exercise and Healthy Lifestyle

Regular exercise helps burn off stress hormones and boost feel-good endorphins. Aim for 30 minutes of activity per day, even if it's just a brisk walk. Establishing healthy sleep habits, eating a balanced diet, and reducing alcohol and caffeine intake can also keep anxiety in check.


Mindfulness involves paying attention to the present moment in a non-judgmental way. This can short-circuit the endless worrying that accompanies anxiety. Try a simple mindfulness exercise like focusing on your five senses or doing a short body scan meditation.

Social Support

Anxiety can be isolating, but surrounding yourself with a strong support system is vital. Confide in trusted friends and family about what you're going through. Join an anxiety support group to connect with others facing similar challenges. Therapists can also provide objective guidance.

Don't struggle alone. Implementing lifestyle changes, learning coping techniques, and utilizing your support system can all help manage anxiety symptoms and give you a greater sense of control.

The Role of the Endocannabinoid System and Endocrine System in Anxiety

The endocannabinoid system plays an important role in regulating anxiety and stress responses. This system consists of cannabinoid receptors found throughout the brain and body, as well as the endocannabinoids that bind to them. When the endocannabinoid system is disrupted, it can lead to heightened anxiety and alterations in mood and cognition.

Research suggests that deficiencies in endocannabinoid signaling may contribute to anxiety disorders. Endocannabinoids like anandamide act as neuromodulators, influencing the release of neurotransmitters involved in anxiety, like serotonin and GABA. Compounds that supplement the endocannabinoid system, like CBD oil, have shown promise in reducing anxiety symptoms.

The endocrine system is also closely tied to anxiety regulation. Stress triggers the release of hormones like cortisol and epinephrine from the adrenal glands. While these hormones help us respond to acute stressors, chronic stress can cause hormonal imbalances that increase anxiety. Hormones like estrogen, progesterone, and testosterone also influence anxiety levels.

Some research indicates that targeting the endocannabinoid system and hormonal regulation may provide new avenues for anxiety treatment. Potential approaches include:

  • Endocannabinoid system modulators like CBD oil to improve deficient signaling
  • Hormone therapies and supplements to restore optimal hormone levels
  • Stress management techniques to regulate cortisol and epinephrine
  • Lifestyle changes like diet, exercise, and sleep to support hormonal balance

While more research is still needed, preliminary studies show promise for therapies that address the endocannabinoid and endocrine systems' role in anxiety. A greater understanding of these complex systems may unlock more personalized and effective treatment options for those suffering from anxiety disorders.
