When work becomes stressful, it can feel as though everything is moving faster than you can manage. Your shoulders may creep towards your ears without you noticing, your attention may narrow, and there may be little room left for humour. Difficult situations, unrealistic schedules and too many projects can all leave you feeling frantic.
Pressures outside work can add to that load. Family difficulties, illness or worries about money may make an already demanding period harder. Some stress is a normal part of life, but when it continues unchecked, it can have a serious effect on both mental and physical health. Recognising changes early can help you respond.
When does stress become concerning?
Ordinary stress is generally temporary and connected to a particular situation or challenge. More concerning stress lasts longer, becomes chronic or feels almost constantly present. An important distinction is how much it interferes with everyday life, rather than simply whether you have felt stressed at all.
Noticing a source of pressure early gives you more opportunity to address it and limit its longer-term impact. You may not be able to change the circumstances themselves. Even then, support and additional ways of coping can help you get through the situation and reduce its effect on you.
Signs are not always obvious
Stress does not always look like someone being visibly overwhelmed. It can show up as a loss of interest in an activity they previously enjoyed. Colleagues or family members might notice the lack of enthusiasm without realising that stress could be behind it.
Looking for changes from someone's usual pattern can be more useful than expecting one obvious warning sign. The main signs fall into four broad areas: physical, emotional, behavioural and cognitive. These areas can overlap, so a change in one part of life may be accompanied by changes elsewhere.
Physical signs: changes in your body
Stress can be felt physically through tiredness, headaches or disturbed sleep. Sleep difficulties can become part of an unsettling cycle, rather than a single bad night. These changes may be easy to overlook during a busy period, particularly when you are focused on getting through your responsibilities.
Appetite can change too. Some people feel less interested in eating, while others crave calorie-dense foods. People may also turn to alcohol or other substances to cope, whether to escape difficult feelings or to unwind when they feel unable to relax otherwise. These changes can be signs worth noticing alongside other shifts in wellbeing.
Emotional signs: changes in how you feel
If your emotions seem different from usual, or less steady, stress could be contributing. You may experience a persistent low mood, feel anxious or irritable, or have a general sense of being overwhelmed. Things you would normally tolerate may suddenly feel harder to handle, leaving you more likely to snap at someone at home or at work.
When considering someone else's wellbeing, pay attention to changes in their mood, words and actions. Do they seem more anxious or easily frustrated? Are they becoming overwhelmed more quickly, losing their temper sooner or worrying much of the time? Have they started overthinking things or lost their usual sense of humour?
Other changes to notice include lower self-esteem, especially if that is unusual for them, difficulty concentrating or making decisions, and avoiding situations they find difficult. These observations do not establish that stress is the cause, but they can help you recognise that something may have changed.
Behavioural signs: changes in what you do
Under pressure, your behaviour may shift in quieter ways. You might pull away from people or activities, put things off, or alter familiar habits and routines. Missing gym sessions or dropping a hobby you normally enjoy could reflect stress rather than a straightforward change of interest.
Work habits can change as well. You may begin working longer hours, take fewer breaks or let the boundaries around your working day slip. These patterns are worth noticing, particularly when they develop alongside withdrawal from activities that previously mattered to you.
Cognitive signs: changes in thinking
Stress can affect your ability to think clearly, reason, plan and analyse. Concentration may become more difficult, and you may be more forgetful than usual. Constant worry, racing thoughts and difficulty reaching decisions can also be part of the picture.
At work, this might feel like being unable to get through your workload, with panic or anxiety following that sense of being stuck. Some of these thinking-related signs also appear alongside emotional changes, which is why it helps to consider the overall pattern rather than treating each category separately.
What to do when you notice stress
Try not to add another layer of pressure by criticising yourself for feeling stressed. Life sometimes brings circumstances you cannot influence or change. Instead, consider what could help in the moment, even if it is something small, such as taking a few deep breaths.
Check whether the things that usually support your resilience are still in place. If they have slipped away, consider how you might restore them. Talking with someone you trust can also help, particularly if you think about what you need from the conversation.
Sometimes you may want help working through a problem, considering your options or finding ways to cope. At other times, you may need someone to stay with you through difficult feelings without trying to solve everything. Being clear about that difference can make support feel more appropriate to the moment.
When to seek further support
If stress is negatively affecting your wellbeing, mental or physical health, or relationships, consider professional support. If you are concerned about someone else but do not feel comfortable discussing it, or think they need professional advice, you can encourage them to speak with their GP.
