Stress vs anxiety: how to tell them apart and why it matters

Stress is your reaction to a pressure you can usually name, such as a deadline, money worries or a sick parent, and it tends to ease once that pressure lifts. Anxiety is worry or fear that carries on after the pressure has gone, spreads to new things, or turns up with no clear cause at all, often about what might happen rather than what is happening. They feel very similar in the body, which is why they get mixed up, and long-running stress can slide into anxiety.

What is the actual difference between stress and anxiety?

The simplest way to put it: stress is about too much now, anxiety is about what if. Stress answers a real demand that’s in front of you. Anxiety is the mind’s alarm going off about possible threats, sometimes with a reason, sometimes long after the reason has passed, and sometimes with none you can find.

Both are normal human reactions. A bit of stress helps you meet a deadline, and a bit of anxiety makes you look both ways before crossing. They become a problem when they’re intense, last a long time or start to shrink your life.

Why do stress and anxiety feel the same in your body?

Because they run on the same system. Whether the threat is a pile of work or a fear of what might happen, your body responds in the same way: it gets ready to act. That’s the stress response, often called fight or flight.

When it switches on, you might notice:

• a faster heartbeat, or being aware of your heart thumping
• quicker, shallower breathing
• tight shoulders, jaw or chest
• a churning stomach or needing the loo more often
• sweating, a dry mouth or shaky hands
• trouble falling asleep, or waking with your mind racing

So the physical feelings alone won’t tell you which one you’re dealing with. The difference shows up in your thoughts and in what happens over time. One caution: chest pain, fainting or sudden breathlessness should always be checked by a doctor rather than put down to stress or anxiety.

How can you tell which one you’re dealing with?

Ask yourself a few questions about the last few weeks. Your answers usually point clearly one way or the other, or show that it’s a bit of both.

1. Can you name what’s causing it? If you can point to a deadline, a situation or a person, stress is likely playing a big part. If the feeling is there but you can’t say why, that leans towards anxiety.
2. If the problem were solved tomorrow, would the feeling go? With stress, mostly yes. With anxiety, the relief often doesn’t last, and the worry moves on to something else.
3. Is your mind on the task or on what might happen? “I have too much to do” is stress talking. “What if I mess it up and lose my job?” is anxiety.
4. Has it outlasted the pressure? Feeling wound up during a hard month is stress. Still feeling on edge months after it ended points to anxiety.
5. Are you avoiding things? Avoidance, such as turning down invitations, putting off calls or not opening emails out of dread, is more typical of anxiety.

Some people with long-running anxiety look calm and capable from the outside, and only they know how much worry is driving them. If that sounds like you, our post on anxiety that hides behind success goes into that pattern.

When does stress turn into anxiety?

Stress can turn into anxiety when it goes on for long enough that your alarm system stays switched on, even after the original pressure has gone. The body gets used to being on high alert, and the mind starts scanning for the next problem.

A common path looks like this: months of pressure at work or at home, poor sleep, no real breaks. Then the pressure eases, but the tension doesn’t. You find yourself worrying about things that never used to bother you, or lying awake going over conversations. The worry has become a habit of its own. Our post on why thoughts get stuck on a loop explains how that habit forms and what helps break it.

Long-running stress can also lead somewhere else: exhaustion and detachment rather than worry. If you feel drained, cynical and like nothing you do makes a difference, the signs of burnout may fit better than anxiety.

What does the DASS-21 show that a single score can’t?

The Depression Anxiety Stress Scales, developed by psychologists Peter Lovibond and Syd Lovibond in 1995, give you three separate scores side by side: one for low mood, one for anxiety and one for stress. The 21-question version looks at the past week only. That makes it especially useful when you can’t tell which of these is weighing on you most.

Its anxiety and stress scales are measured in different ways, which mirrors the difference described above:

• The stress scale asks about tension: finding it hard to wind down or relax, overreacting, feeling wound up or irritable, running on nervous energy, getting impatient.
• The anxiety scale leans on how fear shows up in your body: a dry mouth, trembling, trouble breathing, a racing heart without exercise, feeling close to panic or scared for no good reason.

Each scale’s seven answers are added up and doubled, so each score runs from 0 to 42. The bands are different for each scale:

The pattern is often more telling than any one number. High stress with low anxiety suggests you’re under real pressure but not yet stuck in fear. High anxiety with lower stress points to worry and physical alarm that isn’t mainly about workload. Both high together is common, and a raised low mood score alongside them is worth paying attention to as well. You can see all three scores in about six minutes. Like any questionnaire, it’s not a diagnosis: it shows how much you’ve felt each of these lately, and whether it’s worth talking to someone.

Where does the Perceived Stress Scale fit in?

The Perceived Stress Scale looks at stress over a longer window, the last month, and from a different angle. Developed by psychologist Sheldon Cohen and colleagues in 1983, it doesn’t count stressful events. It asks how unpredictable, uncontrollable and overloaded your life has felt, including how often you’ve felt on top of things and able to handle problems.

Scores run from 0 to 40. There are no official cut-offs, so Sprout describes results in rough thirds of the range rather than comparing you with other people: 0 to 13 is mostly manageable, 14 to 26 is some pressure, and 27 to 40 is a lot of pressure. The most useful way to use the 10-question stress test is to repeat it each month and compare your results with your own earlier ones, for example through a busy season at work or a period of caring for someone.

If you only want to know about worry, the GAD-7 anxiety check focuses on that, with a total from 0 to 21: 0 to 4 few signs, 5 to 9 mild, 10 to 14 moderate and 15 to 21 high.

Does it matter which one it is?

Yes, because what helps is different. Stress mostly responds to changing the situation or your load. Anxiety mostly responds to changing how you relate to worry and fear, because the situation often isn’t the real driver.

What tends to help with stress

• Cut or share the load. Drop, delay or hand over what you can. Say no to new things for a while.
• Solve the solvable part. Write down what’s stressing you and pick one thing you can act on this week.
• Build in real breaks. Short pauses during the day and some time each week that’s properly off.
• Protect sleep and movement. They’re the first things to go under pressure and the ones that make the most difference to how you cope.

What tends to help with anxiety

• Notice the “what if” loop. Naming a thought as worry, rather than treating it as a fact, takes some of its power away.
• Face avoided things gradually. Avoidance brings short-term relief but keeps anxiety going. Small, steady steps towards what you’ve been avoiding help it shrink.
• Cut back on reassurance-seeking. Checking and asking for reassurance feels helpful but tends to feed the worry.
• Consider a talking therapy. Approaches such as cognitive behavioural therapy (CBT) are widely used for anxiety. A doctor can tell you what’s available.

What helps with both

Slowing your breathing, especially making the out-breath longer than the in-breath, is a simple way to ease the body’s stress response, whichever one set it off. The free guided breathing practice takes two minutes, and our post on the 4-7-8 breathing method explains how the different patterns compare.

Should you see a doctor about stress or anxiety?

It’s worth seeing a doctor if either one has been going on for weeks, is affecting your sleep, work or relationships, or if the things you’ve tried aren’t helping. You don’t have to know whether it’s stress or anxiety first. Describing what you feel, when it started and what sets it off is enough.

Go sooner if you’re having panic attacks, if you’ve started avoiding everyday things such as going out or answering the phone, or if you’re also feeling low or hopeless. Sudden waves of intense fear can be confusing, and our post on anxiety and panic attacks explains what each one is. If you’re having physical symptoms that worry you, such as chest pain, get them checked rather than assuming they’re stress.

A simple way to start

If you can name the pressure and the feeling would mostly lift without it, you’re probably dealing with stress, and the most useful move is to change the load. If the worry outlasts the pressure, jumps from topic to topic or has you avoiding things, anxiety is more likely, and it deserves its own attention. If you’re still not sure, you can compare your stress and anxiety scores side by side, or track your stress over the month, and bring what you find to a conversation with your doctor.
