Understanding Anxiety: Symptoms, Causes & Science-Backed Relief
It is almost like anxiety is this quiet, invisible presence that is working away in the background, affecting your thoughts and your body, and it's what keeps you stuck in this circular motion of discomfort.
It is more than worrying. For many of us, it is the presence of this underlying anxiety that simply will not turn off.
You might be experiencing rapid heartbeat, tense muscles, or the nagging feeling that you’re ‘on edge’ all the time. Situations that don’t seem to threaten you might leave you with these feelings. It’s all quite baffling and can even be frightening.
But it’s not just about recognising the symptoms of anxiety. It’s about working out why your body is responding in this way and how you can coax it back to balance.
This article will take you through the symptoms and causes of anxiety and the ways to relieve it.
What is Anxiety?
Anxiety is the body’s natural response to stress, designed to protect you from danger. However, when this response becomes overactive, it can lead to persistent symptoms such as a racing heart, tight muscles, and constant worry—even in safe situations.
At its core, anxiety is your body’s inbuilt system for survival. Your body is wired to detect threats and get you ready to respond as quickly as possible. This system is also known as the “fight or flight” system. This system speeds up your heart rate, improves focus, and releases stress hormones.
This system is good in small dosages. The trouble starts when this system is overactive or overstimulated. Your brain starts to see threats that aren’t really there. This is when anxiety becomes overwhelming. This is also when anxiety becomes an anxiety disorder.
This is when anxiety symptoms appear without any immediate threats. Understanding anxiety at this level is important. This is because it helps you see that you are not “broken.” Your system is overprotecting and overstimulated.
Common Anxiety Symptoms You Shouldn't Ignore
Anxiety symptoms come with various physical, emotional, and mental effects. However, these effects are usually misunderstood and ignored, particularly when they occur without an obvious trigger.
Physical Symptoms of Anxiety
• Racing or pounding heartbeat
• Tense muscles, such as in the shoulders and chest
• Shortness of breath or shallow breathing
• Sweating and chills or changes in body temperature
• Fatigue and dizziness
The physical symptoms of anxiety can be quite severe and may make one think that something is seriously wrong, even when medical investigations do not indicate anything.
Emotional and Cognitive Symptoms
• Persistent worry or fear
• Feeling restless or constantly on edge
• Trouble concentrating or “brain fog”
• Irritability or emotional sensitivity
• Sleep disturbances
In addition, sleep disturbances can also contribute to an increase in anxiety. Many people find their symptoms intensify at night when rest becomes inconsistent—a pattern closely connected to deeper sleep issues, as explored in our guide on conquering insomnia for better sleep.
What Causes Anxiety? (The Hidden Causes)
Anxiety is all about digging deeper than the surface symptoms. It’s about finding what’s causing your anxiety in the first place.
1. Chronic Stress
Chronic stress is stress that is ongoing. It’s what happens when your body is in a state of heightened alertness. This is not good. Your nervous system is constantly on high alert. Eventually, your nervous system gets used to being in that state, even if there is no more stress.
2. Negative Thought Patterns
How your brain learns is by repetition. If you always think that bad things are going to happen, your brain is going to think that way too.
This is why learning how to observe and manage your emotional responses, similar to techniques used in building emotional balance, can help break this pattern over time.
While avoidance behaviour might give you relief in the short term, in the long term, it will make your anxiety much worse. Every time you avoid something, your brain is learning that something bad is going on. That’s why your anxiety is always there.
4. Lifestyle Causes
• Sleep deprivation
• Most caffeine consumption
• Lack of physical activity
All of these can make your nervous system more sensitive. Your nervous system is what makes your anxiety symptoms more or less visible.
Nutrition and daily habits also play a subtle but powerful role, particularly when it comes to energy levels and mental clarity—something further explored in our guide on foods that boost focus and reduce brain fog.
5. A Sensitised Nervous System
One of the most neglected contributors to anxiety states is a nervous system that has become too sensitive.
This is where anxiety moves away from external events and into how your nervous system responds to your internal world.
This is also why body-based approaches are becoming more widely used, especially simple techniques like somatic exercises for stress relief, which focus on calming the body rather than overthinking the mind.
Why Anxiety Feels Like a Trap (The 5F Cycle)
One of the primary reasons for the persistence of anxiety is that there is a strong cycle that is often termed the 5F cycle.
The 5F Cycle Explained
• Fear - You notice a symptom (e.g., a racing heart)
• Focus - Your attention zooms in on it
• Fix - You try to control or eliminate the feeling
• Frustration - The sensation doesn’t go away
• Fear (again) - The cycle restarts
This cycle is responsible for making anxiety feel like a trap from which there is no escape.
The more you attempt to fix your anxiety, the more you focus on it, and hence, it gets even stronger. This is why your anxiety feels like a trap that cannot be escaped by thinking your way out.
However, escaping this cycle requires a new approach that is more about comprehension than control.
Science-Backed Anxiety Relief Strategies
The good news is that anxiety is highly manageable. Research has shown time and again that it is possible to alleviate anxiety considerably by using a mix of mental and physical techniques.
1. Regulate Your Nervous System
The body is the source of anxiety, and therefore, it is vital to calm your nervous system.
Some of the techniques include:
• Slow and deep breathing
• Grounding techniques
• Mindfulness techniques
Some people also find additional relief through gentle pressure-based techniques, similar to methods used to unlock calm with acupressure, which can help release built-up tension in the body.
2. Break the Avoidance Cycle
The avoidance cycle is what maintains the anxiety.
Working through the avoidance at your own pace is one of the most well-researched methods of treating anxiety.
3. Reframe Anxious Thoughts
Your anxious thoughts may seem true, but they are not necessarily true.
Being able to challenge your anxious thoughts and challenge them in another way is one of the most powerful weapons against anxious thoughts. Emotional regulation is key to this process.
4. Improve Sleep and Recovery
Sleep is one of the key factors that affect emotional stability. If your sleep improves, your symptoms of anxiety will be reduced too. It is good to create a routine that will aid in the improvement of your sleep.
5. Use Physical Relaxation Techniques
There are physical interventions that help your brain feel safe.
This may include:
• Gentle movements
• Stretching
• Using pressure-based techniques such as acupressure
This helps your brain to release anxiety and consequently reduce the symptoms of anxiety.
When Anxiety Turns into Anxiety Disorder
While anxiety is a normal part of the human experience, if the following conditions are met, the presence of anxiety could be a symptom of an anxiety disorder:
• The anxiety has lasted for a long time
• Your daily life is becoming increasingly difficult to manage
• You are feeling trapped, overwhelmed, or unable to relax
Final Thoughts: Breaking Free from the Anxiety Cycle
Recognising anxiety is a powerful step towards recovery. What may seem like a never-ending, silent struggle is actually a product of a nervous system that is overprotecting itself, not a broken one.
While recognising the symptoms of anxiety and the underlying cause of it, and implementing the scientifically-based methods of relieving it, it is possible to step out of the cycle of anxiety.
It may take some time, but it is possible.
