Have you ever felt your heart race before a meeting, even when nothing dangerous was happening? Or woken up with a knot in your stomach without knowing why? These reactions can feel confusing, but anxiety affects more than your thoughts. Your body responds to stress, too.
According to Statistics Canada, 5.2% of Canadians aged 15 and older met the criteria for generalized anxiety disorder in 2022, compared with 2.6% in 2012. These figures show how common anxiety can be, yet its effects often go beyond emotional discomfort.
You might notice tight shoulders while working, headaches after a demanding day, or an unsettled stomach before an important conversation. These sensations are easy to dismiss as everyday stress, especially when you do not feel particularly worried. Understanding the connection between anxiety and physical symptoms can help you recognize patterns and decide when further support may be useful.
What Happens in the Body During Anxiety?
For every threat you perceive, your body has an alarm system that allows you to prepare for it. The amygdala is a part of your brain that becomes active when there is a danger or threat, and triggers a stress response that releases hormones like adrenocorticotropic hormone (ACTH), adrenaline, and cortisol. The Government of British Columbia provides the following explanation of what this response does for the body in preparation for action, even if there is no physical danger.
Your heart rate may increase, your breathing may alter, and increased blood flow to your muscles may occur as your response progresses. Ontario Science Centre describes how these alterations enable the body to respond. You may also notice your senses are keener and that you are more aware of the ordinary sounds or sensations that are around you.
These physical changes can also have an impact on your emotions. You may experience fear, anxiety or agitation or the freeze response may cause you to feel stuck or foggy. According to Anxiety Canada, fight, flight and freeze are the natural reactions to perceived threats. In fact, when you notice a racing heart and become frightened by it, the additional stress can contribute to the physical feelings being even stronger.
6 Physical Symptoms Anxiety Can Trigger
The stress response can manifest in various ways; anxiety may present as tight muscles, breathing changes, or digestive upset, among other symptoms. Understanding these symptoms can help to make them easier to understand, but the presence of these symptoms alone will not confirm anxiety as the cause.
- Muscle tension: Your muscles tighten when your body is getting ready for action. That tension can remain around the jaw, neck and shoulders if the stress persists. Otherwise, you may also bite your teeth at night without even noticing you’re doing it. Medimap explains the relationship between anxiety and muscle tension and discomfort.
- Rapid heartbeat: Adrenaline makes the heart pump faster to get your body ready for activities. At an anxious time, someone may experience pounding, fluttering or an awareness of the heart beating, even when they are sitting down. These feelings can be symptoms of anxiety, but if you are experiencing new or unexplained heart symptoms, you shouldn’t assume they are stress-related.
- Headaches: Neck, scalp and surrounding muscle tension may be a cause of headache, particularly during stressful times. Low sleep quality, a lack of nutrition, and sitting for hours at a computer can contribute to discomfort. When headaches continue to recur, it may be useful to keep a headache diary to review with a health care provider to identify potential causes.
- Stomach discomfort: Your brain is in touch with your digestive system via an intricate system of messages. As Harvard Health explains, this connection can influence digestion and how your stomach feels. In anxious times, you might have nausea, cramps or heartburn and these can cause more worry.
- Sweating: Sweat glands in your body can be stimulated by stress hormones, which can cause your palms, armpits or forehead to sweat even if you’re not active. This may be observed prior to an address or in an uneasy dialogue. Being afraid to sweat, or that others will notice the sweat, can then exacerbate an already stressful situation.
- Breathing changes: You may find that your breathing is either quicker or shallower than normal, due to anxiety. At times, rapid breathing can cause a decrease in carbon dioxide levels in the blood, which can lead to dizziness, tingling or light-headedness. According to Johns Hopkins Medicine, hyperventilation can cause the following effects on the body. If breathing problems are recent, more serious or unexplained, get medical advice, don’t just assume it is due to anxiety.
Why Do Anxiety Symptoms Feel Different From Person to Person?
Everyone experiences anxiety differently, as people react differently to stress, their experiences and feelings of physical sensations. Symptoms may also vary based on age and other factors. There were differences across population groups: Between 2012 and 2022, the incidence of generalized anxiety disorder tripled among women aged 15 to 24, according to Statistics Canada.
The differences may be compounded with everyday behaviors. Consider two co-workers that are both on a tight deadline, one has had a proper night’s sleep and proper meals over the past few days, while the other has slept little and has been relying on a few extra cups of coffee. The first could feel stress, while the second could experience a more noticeable heart rate, muscle tension or inability to concentrate.
How you perceive a sensation is important, as well. While a fast pulse may not appear to be a problem to one person, it may seem to be to someone who is health conscious. Psychology Tools discusses how normal body sensations can be misinterpreted as a warning and result in greater anxiety. Understanding this can make you more aware of how you are reacting, rather than springing into your automatic negative behavior.
How Can Anxiety Symptoms Interfere With Daily Life?
When physical symptoms begin to interfere with everyday life, relationships or work, it may be more difficult to manage them. After a bad night’s sleep you might find it hard to focus the following day, and on the day of the meeting, if your heart is pounding, you may find it difficult to listen to what someone is saying. Over time, these effects may appear in several areas of daily life, such as:
- Sleep disruption: Racing thoughts and muscle tension may make it hard to fall asleep or to stay asleep. According to Canada’s 24-Hour Movement Guidelines, adults 18 – 64 years old should get 7 – 9 hours of sleep. Everyday stresses may be more difficult to manage when you are tired the next day due to poor sleep.
- Reduced concentration: If you keep getting back to how things feel and what might be wrong, it can be more difficult to do daily tasks. You may have to read the same paragraph again, miss meetings or find it hard to get your thoughts in order. This can be frustrating, especially when you know what you need to do, but can’t concentrate.
- Lower energy: You may feel exhausted when you’re stressed and alert all day long. Simple tasks can feel like a burden if you’re sleep-deprived or have spent hours worrying. The fatigue can make it more difficult to keep up with routines and could cause an additional aggravation in an already stressful day.
- Appetite changes: Anxiety can cause a change in appetite, either an increase or a decrease. May not be able to settle down enough to eat or eat more often to get comfort. As these changes progress, it may be more challenging to eat well at regular intervals, which can impact your energy level and make it more difficult to handle everyday activities.
- Social withdrawal: You might prevent yourself from attending events or from talking to other people if you’re afraid that they will notice your shaking, sweating, or discomfort. While it may help to cancel plans and get some relief from the situation, but if it’s a situation that’s kept avoided, that can make it harder to reconnect. However, maintaining relationships with supportive individuals can offer support without making you feel like you are overloaded.
- Work difficulties: Anxiety symptoms may make meetings, deadlines and decision-making more challenging. It can be hard to focus on the task as you’re busy managing a tight chest or tense shoulders. Knowing the signs can prompt you to think about making some changes to your work and getting the right support if you find it just becomes too much.
What Everyday Factors May Make Physical Symptoms Worse?
When anxiety symptoms start to interfere with daily life, there are some habits and pressures which might exacerbate the symptoms. You might feel more awake after a poor night’s sleep, a busy schedule or after consuming several caffeinated drinks. Looking at these everyday factors can help you identify patterns without blaming yourself for how your body responds.
- Sleep patterns: With a short sleepless night, minor concerns may seem more difficult to deal with, and your body may be more sensitive to stress. You can also be disrupted by an irregular sleep schedule. Having regular sleep hours and waking times can help you to sleep better and cope with demands of daily life.
- Daily pressures: Deadlines, family pressure and constant uncertainty can keep the stress response going for extended periods of time. If you aren’t getting much time between demands, muscle tension and digestive discomfort may be more apparent. Making the tasks simpler, and allowing time to pause can help make a busy day feel less overpowering.
- Lifestyle habits: Eating too little and staying in a sitting position for long periods of time can cause sluggishness or discomfort. The guidelines for movement in Canada suggest that for adults 18-64 years, try to spend no more than 8 hours a day sitting. Incorporating short movement breaks throughout the day can give you opportunities to move and add activity to your day.
- Stimulants: Caffeine from coffee, energy drinks, and other sources can make you more awake and at times can cause a racing heartbeat or jitteriness. The recommendation from Health Canada for healthy adults is that they should not have more than 400 mg of caffeine a day. The University of Guelph also recommends to not consume caffeine 4-6 hours prior to going to bed.
What Can Help You Manage Anxiety Related Physical Symptoms?
It’s not necessary to completely alter your way of life to start dealing with discomfort related to anxiety. Practicing these small, realistic habits could help you to promote better sleep, have more energy, and get through daily stressors. The most effective strategy is the one that can be adhered to regularly, so try these simple steps.
- Regular sleep: Try to go to bed at the same time and get up at the same time to get into a regular routine. As an adult (18-64) get 7-9 hours of sleep, and allow yourself time to unwind before you go to bed. Cutting back on late-night screen time can help make that transition easier, too.
- Balanced meals: Regular meals will help you get a steady supply of energy for the day. Consider pairing protein with fibre from carbohydrates, like eggs and whole-grain toast or beans and brown rice. Planning simple meals and snacks in advance might help if you find that you feel shaky or unsettled when you miss meals.
- Gentle exercise: Adults should aim to get 150 minutes of moderate to vigorous physical activity in a week, according to Canada’s physical activity guidelines. You can work up to this amount over a period of time, by walking, biking, or whatever activity you choose. Exercise can also be a good distraction from work and daily stress.
- Relaxation techniques: Listening to music or playing soothing music, taking a warm bath or hot tub, or using progressive muscle relaxation can help you relax. Progressive muscle relaxation is the technique of relaxing and tensing the various muscle groups in a gentle manner. Experiment with a few and see which ones you feel comfortable with and that you can easily fit into your day.
- Breathing exercises: If your breathing feels rushed as a result of your anxiety, slowing down and making it gentle can help you to feel more settled. Practice breathing in and out comfortably; let the out-breath be a little longer, but do not try to take a deep breath. If a specific exercise causes greater discomfort, discontinue the exercise and try another.
- Stress management: Putting your worries on paper, dividing big projects into something more manageable or establishing reasonable limits can help stress seem more manageable. You can also discuss issues with a trusted friend or counsellor, which can help you to tackle any ongoing worries. You don’t need to solve it all at once to start making changes.
When Should Persistent Physical Symptoms Be Evaluated?
Physical symptoms are worthy of investigation if they persist, cause problems with daily activities or can’t be explained. Anxiety may lead to actual physical changes, but it is not necessarily the only cause. Being aware of the progression of the symptoms will enable you to know when to seek expert advice from a healthcare provider.
- Persistent symptoms: If a racing heartbeat, headache or stomach discomfort does not improve after a longer period of time, seek a medical assessment. Any symptoms that keep coming back and disrupt your sleep or daily life should be addressed, too. Instead of having to figure out the reasons for your experiences by yourself, a healthcare provider will be able to review them and provide suggestions for any potential explanations.
- Increasing frequency: Determine if there are more symptoms or they are occurring more often, or if they are more difficult to manage. A short note of when they occur and how long they last, and what was happening before them, could help to explain the pattern during an appointment.
- Daily disruption: If your symptoms make it difficult to work, sleep, study or maintain relationships, it’s time to see your health care provider. Also watch for when you start avoiding activities that you normally do because you’re afraid your body will respond in some way. Support can assist you to understand what is happening and contain information about what you can do next.
- New or concerning symptoms: Don’t assume that new or different physical sensations are due to anxiety. However, if there are problems with breathing or if a person develops new symptoms, such as chest discomfort, it may be due to other causes, and should be evaluated accordingly.
- Unclear causes: If symptoms persist and there is no clear link to stress, consult with the health care provider. Sometimes, shakiness and rapid heartbeat are attributed to dysfunction of the thyroid glands or of the blood sugar. An evaluation may help to distinguish between various possibilities and may direct the next steps.
