How to Reduce Stress: Nutrition, Movement, CBT and Breathwork

How to manage stress when it becomes too much

You already know what stress is. You recognise the symptoms of stress and have felt how stress affects the body: tight shoulders, racing thoughts, broken sleep.

So how can we manage stress when it threatens to take over?

The techniques below work in different ways to reduce stress levels. What works depends on how your symptoms manifest.

If that is tension or restless energy, start with movement. If you tend to overthink or catastrophise, cognitive behavioural therapy (CBT) may be the right starting point. If stress hits as panic in the moment, breathwork can help.

Nutrition and sleep set the level you start each day at. If one approach is not working after a few weeks, try another or combine them.

How to reduce stress with movement and exercise

Exercise and stress relief are closely connected. Regular activity can lower cortisol over time and increase “feel-good” endorphins, helping improve mood and reduce tension. People who exercise at least once a week recover faster from stress and experience smaller dips in mood.

You do not need long sessions. The NHS recommends 150 minutes of moderate activity per week. If you only have 10 minutes, a brisk walk still helps.

Yoga and pilates are great forms of physical activity because they combine movement with slow breathing. Studies show that yoga has the largest cortisol-lowering effect among the exercises examined.

If you are already burnt out, high-intensity exercise can make things worse. Start with walking and build from there. If exercise consistently leaves you more drained than before, that may be a sign you need rest, not more activity.

Breathwork, relaxation and mindfulness for stress

Stress often appears at night. You lie awake, thoughts racing, chest tight. Fast, shallow breathing signals to your brain that danger is near, triggering the release of more stress hormones.

In the moment, how to relieve stress often comes down to reversing this pattern. Slowing your breath and extending the exhale activates your parasympathetic nervous system. This acts as the brake to your stress response.

The British Heart Foundation describes the 4-7-8 method. Breathe in for 4 counts, hold for 7, breathe out slowly for 8. Box breathing is another option: close your eyes, inhale for 4 counts, hold for 4, exhale for 4, hold for 4.

If that feels too long, the NHS suggests a simpler approach. Breathe deep into your belly, in through your nose and out through your mouth, counting to 5 each way.

Breathwork for stress does not require equipment or training, though apps like Headspace or Calm can help if you prefer structure.

If breathing exercises make you feel more anxious rather than calmer, try progressive muscle relaxation instead. Tense each muscle group for five seconds, then release. Start with your feet and work upward. The physical release can help interrupt the stress cycle if focusing on your breath feels hard.

CBT for stress

NICE recommends CBT for stress-related conditions because of strong trial evidence showing it helps. The approach works at the level of thought. Thoughts, feelings, body sensations, and actions are all linked. Change the thought pattern, and the body often follows.

Here is how it works in practice:

You send an email, and your manager does not reply for two hours. You assume you have made a mistake and that your job is now at risk. CBT helps you recognise that you are catastrophising and challenge the thought before it spirals out of control. It gives you a framework for responding to any stressful situation.

You do not need a GP referral to access CBT. In England, you can self-refer to NHS Talking Therapies if you are 18 or over and registered with a GP.

CBT takes time and practice. It requires engagement and homework between sessions. Once learned, it reshapes how to cope with stress long-term.

If you are not seeing any shift after six to eight sessions, discuss this with your therapist. If your stress is primarily physical, movement or breathwork may be better starting points. But if overthinking drives your stress, CBT targets that pattern directly.

Nutrition and stress

You might think comfort food helps with stress. In the short term, it does. Sugar and fat trigger the release of dopamine, which feels good.

Diets high in processed food can raise cortisol, increase inflammation, and make weight harder to shift. The connection between stress and your weight is often underestimated.

The Mediterranean diet works the other way. It emphasises vegetables, fruits, whole grains, legumes, nuts, fish, and olive oil. A 2023 clinical trial found people following a Mediterranean diet had lower cortisol levels first thing in the morning. These foods appear to reduce inflammation, which helps your body recover more easily from stress.

Three changes matter most.

Eat regular meals to keep blood sugar steady. Skipping meals can trigger a stress response.
Reduce ultra-processed food where possible and replace it with whole foods.
Cut caffeine after early afternoon. It stays in your system for hours and blocks the brain chemicals that help you wind down.

No supplement will fix a poor diet, but some have shown promise for reducing stress. A 2017 review found magnesium may reduce anxiety, while another 2019 study found that ashwagandha may lower cortisol levels. However, evidence for both is limited.

Speak to a pharmacist or GP before starting supplements to check they are safe and will not interact with other medicines.

Managing stress through sleep

Most people try to fix sleep last. But you cannot out-exercise or out-breathe a pattern of broken nights.

Sleep and cortisol affect each other. When one suffers, the other often follows, creating a cycle that is hard to break without addressing both. Multiple studies show that exercise improves sleep quality and reduces cortisol levels. This only works if you do not sacrifice sleep to fit in the workout.

Sleep hygiene is key. The NHS Every Mind Matters programme recommends:

a consistent wake-up and bedtime every day
an hour of screen-free wind-down
a cool, dark, quiet room

Place your phone on silent and consider using earplugs if you are a light sleeper. Or white noise can be another helpful option for many people.

Sleep apps and trackers can make sleep anxiety worse. Checking your sleep score every morning adds a new stressor.

If sleep problems persist for more than 2 weeks despite these changes, or if you wake up unrefreshed every day, speak to your GP.

How to deal with stress at work

When you dread Sunday evenings or check emails before getting out of bed, work stress has become a problem. The NHS recommends taking control where you can, even in small ways, as feeling powerless often makes stress worse.

Batch your email and set up two or three windows during the day to process messages. Outside those windows, turn off your notifications. The constant ping can keep your fight-or-flight response active.

Decide in advance how to push back: “I cannot take this on right now, but I could look at it next week.”

Take breaks away from your desk, and go outside if you can. A 2019 study found that 20 minutes spent outdoors lowered cortisol by more than 20%.

Chronic work stress takes a toll. If you are noticing stress and blood pressure changes, or effects on hormones, take it seriously. The links between stress and menopause and between stress and erectile dysfunction are stronger than most people realise.

If these strategies are not enough, talk to someone: your manager, HR, a colleague, or a friend. The NHS lists social connection as one of its key stress-busters. If your workplace pushes back on boundaries, that is a problem with the environment, not with you.

Why most stress advice fails

Most stress advice assumes you have time, energy, and headspace to spare. If you are already running on empty, adding a new habit can feel like another demand. This is why starting with what you can manage beats doing everything at once.

Being stress free is not a realistic goal. Some stress is useful. It sharpens focus before a presentation or pushes you to meet a deadline. The aim is not to eliminate stress but to recognise when it is helpful and when it becomes a problem.

When should I see a doctor?

Self-help works for everyday stress. If you have an existing condition or take regular medication, speak to your GP before trying new approaches.

See your GP if chronic stress is affecting your physical and mental health, and these techniques are not helping after a few weeks. Physical signs worth noting include persistent headaches, chest discomfort, or significant weight changes. Stress can also show up in ways you might not expect. The links between stress and hair loss and stress and your skin are often overlooked.

If left unaddressed, ongoing stress can contribute to mental health problems. If you are struggling to cope, have thoughts of self-harm, or feel unsafe, this is urgent. Call NHS 111 for advice.

In an emergency, call 999 or go to A&E. Asking for help is a sign of strength.

Not all stress is a crisis, but it can affect everyday goals. Your GP can discuss options that may help with managing stress through your weight loss journey.

Key takeaways

If you do one thing: match the technique to how your stress presents itself. Movement helps if stress sits in your body as tension. CBT works best for negative thoughts. Breathing techniques are useful when feeling overwhelmed.
If you can do two, add sleep hygiene: a consistent bedtime, screen-free wind-down, and a cool, dark room.
To go further: shift toward Mediterranean eating, cut caffeine after noon, and get outside during the workday.
If nothing helps after a few weeks and feelings of stress are affecting your daily life, see your GP for support.
