Reduce stress: the methods with evidence behind them, for a full diary

Stress is not the enemy, the excess is

The WHO definition is worth reading slowly. Stress is a response to a difficult situation, and a moderate dose is useful: it sharpens attention before a negotiation and gets a report finished. The problem is pressure that never lets up, so the response stays switched on through the evening and into the night.

The aim is therefore not to feel nothing. It is to come back down between peaks. Each method below works on that return, from a different angle.

The WHO's five habits

WHO's public guidance on coping with stress is brief and practical. It comes down to five habits.

• Keep a daily routine, with set times for meals, family and exercise.
• Get plenty of sleep.
• Be physically active during the day, which WHO notes also helps you fall asleep at night.
• Connect with others, which can lift mood and lower the sense of stress.
• Eat healthily.

WHO also publishes an illustrated guide, Doing What Matters in Times of Stress, which teaches self-help skills. It states that a few minutes each day are enough to practise them. That matters for someone who will not add an hour of anything to the day.

Exercise: a measured effect, with limits

The evidence on activity and mental symptoms is now large. The umbrella review by Singh and colleagues pooled 97 reviews and found effect sizes of 0.43 for depression, 0.42 for anxiety and 0.60 for psychological distress. Those are meaningful effects for something that also improves fitness and sleep at no cost.

The NHS puts it in plain words: exercise will not make your stress disappear, but it can reduce some of its emotional intensity. That is the right expectation.

There is a longer-term benefit too. A meta-analysis by Forcier and colleagues found that fitter people showed smaller rises in heart rate and blood pressure in response to psychological stressors. Fitness does not make a crisis smaller; it may make the body's reaction to it smaller.

For a busy diary, frequency matters more than heroics. A brisk 30-minute walk on most days reaches the WHO minimum of 150 minutes a week. On heavy weeks, the guide to exercise and stress explains how to adjust intensity so that training relieves the load instead of adding to it. A walk can even replace a seated meeting: see walking meetings.

Mindfulness training

Mindfulness-based stress reduction is a structured course in meditation and attention, usually taught in a group. A meta-analysis by Khoury and colleagues covered 29 studies and 2,668 healthy adults. Compared with control groups, the overall effect was moderate, with an effect size of 0.53. The effects were large on stress, moderate on anxiety, depression and quality of life, and small on burnout. The studies varied widely, so the size of the benefit is uncertain.

WHO's 2022 guidelines on mental health at work also say that stress-management training based on mindfulness or cognitive behavioural approaches may be considered for workers. If you prefer structure, a course run by a qualified instructor is one of the better-supported options.

Five minutes of breathing

Breathing is the fastest tool, because it needs no equipment and no change of place. In a one-month remote trial by Balban and colleagues, five minutes a day of cyclic sighing, a slow breathing pattern with long exhalations, improved mood and lowered breathing rate more than the same time spent in mindfulness meditation. Most participants were university students, and the authors list the remote format as a limitation.

The NHS offers a simple version: breathe in and out gently, counting to five each way if that helps, for at least five minutes. Slow breathing at about six breaths a minute has its own body of research, explained in coherent breathing. The calculator above counts ten minutes a day of any such practice as a habit in place. That threshold is our convention, chosen to sit just above the five minutes used in the trial.

Sleep, the base under everything

The American Academy of Sleep Medicine and the Sleep Research Society recommend 7 hours or more a night for adults. Sleep loss and stress feed each other. In a laboratory study by Leproult and colleagues, partial sleep deprivation raised cortisol the next evening by 37%. A stressed mind sleeps worse, and a short night leaves the next day's stress response running higher.

When pressure rises, protect the night first. Sleep for executives lists the habits that carry the most weight, and the guide to HRV explains how some people follow the effect of short nights on their own body.

What we could not verify

Supplements, cold-water immersion and so-called adaptogens are widely sold as stress remedies. We found no evidence strong enough to recommend them here, so this guide makes no claim for them. If you are tempted, ask your doctor, particularly if you take other medicines.

Putting it into a working week

A realistic minimum, built from the evidence above, fits into about 40 minutes a day.

1. A 30-minute walk or session, most days.
2. Five to ten minutes of slow breathing, before the first meeting or after the last.
3. A fixed time to stop work, early enough to leave seven hours for sleep.
4. One conversation a day that is not about work.

Use the calculator to see which of the three measurable habits are in place: activity, sleep and a daily calming practice. Then add the missing one, not all of them at once.

When stress needs more than habits

See a doctor if you are struggling to cope, or if the things you try yourself are not helping, as the NHS advises. If stress stops you sleeping, working or enjoying life for more than a couple of weeks, do not wait. If you are in crisis or think about harming yourself, contact emergency services now.

Habits are easier to hold when someone else organises them. A coach of the Club plans sessions around your diary and adapts them to the state you arrive in. Your space opens with one email.
