What Is the Difference Between Stress and Anxiety?
You might feel tense after a difficult day, lie awake thinking about everything you need to do, or find your mind jumping from one worry to another. When this happens, it can be hard to know what you're actually experiencing. So, what is the difference between stress and anxiety? Although they can feel very similar, stress and anxiety aren't quite the same.
Understanding what may be behind these feelings can help you make sense of your experience without blaming yourself for struggling.
What Is Stress?
Stress is your body's natural response to pressure or demands. It can happen when you have a lot to manage, face an important deadline, deal with conflict or go through a significant change in your life.
Perhaps work has become particularly demanding. You might be caring for your family while trying to keep up with everything else, or you may be dealing with financial pressure, relationship difficulties or an unexpected change.
When you're under stress, your body can move into a heightened state of alertness. You might notice:
Muscle tension or headaches
Feeling overwhelmed or irritable
Difficulty concentrating
Changes in your sleep
Feeling tired or drained
A racing heart
Changes in your appetite
Stress isn't always harmful. In some situations, it can help you respond to a challenge and focus on what needs to be done. The difficulty can come when stress becomes intense, happens often or continues for a long time without enough opportunity to recover.
What Is Anxiety?
Anxiety involves feelings such as worry, fear, nervousness or apprehension. It can arise when you anticipate something going wrong or feel uncertain about what might happen.
You might find yourself thinking through every possible outcome before an important event. Perhaps you keep worrying about something even when you can't identify exactly what you're afraid will happen. Your body may also respond, leaving you feeling restless, tense, shaky or unable to switch off.
Some common signs of anxiety include:
Persistent or difficult-to-control worry
Feeling restless or on edge
Racing thoughts
Difficulty concentrating
Trouble sleeping
Increased heart rate
Avoiding situations that cause fear or worry
Feeling tense or unable to relax
Anxiety is a normal human response at times. You might feel anxious before an interview, medical appointment or difficult conversation. However, anxiety can become harder to manage when it persists, feels overwhelming or begins to interfere with your everyday life.
Why Do Stress and Anxiety Feel So Similar?
Understandably, stress and anxiety are often confused because they can affect your thoughts, emotions, body and behaviour in similar ways. The key difference often lies in what is driving the response and whether it eases when the situation changes.
Stress is usually linked to a specific pressure or demand, such as several work deadlines, and may settle once the pressure passes. Anxiety can continue even when there is no immediate problem, with ongoing worry about what might happen or things going wrong.
That doesn't mean the two are completely separate. Ongoing stress can contribute to anxiety, and anxiety can make everyday pressures feel harder to manage.
Stress | Anxiety |
Often linked to a specific pressure or demand | Can involve worry about potential threats or uncertainty |
Usually connected to something happening in your life | Can continue even when there is no immediate threat |
May ease when the stressful situation is resolved | May continue even after the original situation has passed |
Can leave you feeling overwhelmed or under pressure | Can involve persistent worry, fear or apprehension |
If you're experiencing both, you don't need to work out exactly which label applies to you. What matters is understanding how you're feeling and how much it's affecting your life.

FAQs
What's the difference between stress and anxiety?
Stress is usually a response to a specific pressure or demand, while anxiety can continue even when there is no immediate problem to solve. They can feel very similar, and you can experience both at the same time.
Can anxiety cause physical symptoms?
Yes. Anxiety can affect your body as well as your thoughts and emotions. You may experience a racing heart, muscle tension, headaches, sweating, shakiness, stomach discomfort or difficulty sleeping.
When should I see a psychologist?
Consider speaking with a psychologist if anxiety, stress or other concerns are affecting your sleep, relationships, work or everyday life. You don't need to wait until things feel overwhelming to ask for support.
How do I know if I need therapy?
Therapy may be helpful if you're finding it difficult to manage your thoughts, emotions or behaviour on your own, or if something is getting in the way of your daily life. A psychologist can help you understand what's happening and work out what support may be right for you.
How can I relieve stress and anxiety?
Start by identifying what's contributing to how you feel and give yourself opportunities to slow down and recover. Regular sleep, movement, time away from ongoing demands and talking to someone you trust can help. If stress or anxiety continues to interfere with your life, professional support can also help.
How can I sleep with anxiety?
Try giving yourself time to wind down before bed and avoid working or repeatedly checking your phone when you're trying to sleep. If your thoughts are racing, writing down what's on your mind can help you step away from it for the night. If anxiety regularly keeps you awake, a psychologist can help you address what's driving it.
Can anxiety cause sleep deprivation?
Yes. Anxiety can make it difficult to fall asleep, stay asleep or switch off at night. Poor sleep can then leave you more tired and less able to cope with worry the next day, creating a difficult cycle.
Why am I so anxious all the time?
Ongoing anxiety can have many possible causes, including prolonged stress, difficult life experiences, uncertainty or patterns of worry that have become hard to switch off. There isn't always one obvious reason. If anxiety is persistent or affecting your everyday life, speaking with a psychologist can help you understand what's contributing to it.
