The benefits of walking

Walking is often called the perfect exercise. It’s remarkable something so simple – putting one foot in front of the other – can be so restorative and invigorating. But the medical evidence is compelling. Taking regular brisk walks helps you stay healthy, live longer and boosts your self-esteem and mood.

Television presenter and Ramblers president Julia Bradbury is the modern face of walking. Her passion started as a six-year-old in the Peak District with her father: ‘I love the Peak District and, over the years, walking with Dad through the valleys and limestone hills, I developed a comfortable outdoor spirit.’
Bradbury’s television series Wainwright Walks and Railway Walks have helped inspire a renewed interest in country walking. A Ramblers survey revealed 77 per cent of UK adults – about 38 million people – walk for pleasure at least once a month. Of these, 62 per cent cover more than two miles a time. With so many demands on our time, it can be hard to make space for a worthwhile walk. But if you can manage to fit one in, the payback can be enormous – an all-round lift for the mind, body and soul.
1. Refresh your mind
There’s something about the regular roll and rhythm of walking that frees the mind and sparks creative connections, so it’s not surprising many writers have used walking to stimulate creativity. ‘Walk and be happy, walk and be healthy,’ said Charles Dickens. A phenomenal walker, in his diaries he recorded how, during 20-mile treks, he would come up with the plots for his novels.
Whether you’re dreaming up your own bestseller, or figuring out a challenge at work or home, walking gives you time to reflect. ‘I try to walk home from the office once or twice a week,’ says Katie, 26, from north London. ‘It helps me escape my computer and emails, and gives me space to think through new projects.’ For children, the words ‘let’s go for a walk’ might trigger groans of protest, but with a little imagination you can turn a trial into a treat. ‘Children need paths to explore… paths down the garden, the way to school, corridors through the bracken or long grass,’ wrote the late travel writer Bruce Chatwin.
If you can, create ways to plan routes that will trigger children’s curiosity and sense of discovery. Sarah, 38, from Tonbridge in Kent, uses a storytelling approach with her nieces, Becky, seven, and Amelia, five. ‘I devised a short route around the Ashdown Forest where we read out a few snippets from Winnie The Pooh and even played a game of Pooh Sticks. The girls were hooked.’
2. Boost your body
‘Walking is man’s best medicine,’ said Ancient Greek physician Hippocrates, although he was probably talking more from gut instinct than medical research. These days, there is plenty of scientific evidence to show that regular walking helps reduce the risk of high blood pressure, raised levels of cholesterol, heart disease, stroke, type 2 diabetes and some cancers.
The government recommend at least 30 minutes of brisk walking or other physical activity five times a week. ‘Brisk’ meaning you will breathe a little faster than normal, feel warmer and your heart beats slightly faster, but you are still able to carry on a conversation.
As a result, walking programmes are on the rise. In the London borough of Tower Hamlets, sustainable transport officer Rachel Maile has set up a Walks On Prescription scheme, where local GPs can refer patients for a 10-week programme. ‘By joining our weekly walks, participants can proactively manage their weight, diabetes and other health conditions,’ says Maile. ‘They’re given a step counter and encouraged to monitor their progress, week by week, towards a more active lifestyle.’ Even going for a relatively short daily stroll can help. ‘Studies show people who walk at least part of the way to work are more productive, happier and off sick less,’ says Maile.
3. Restore your soul
As Slow Movement pioneer, and author of In Praise Of Slow, Carl HonorĂ© says, ‘Travelling on foot can be meditative, fostering a slow frame of mind. When we walk, we are aware of the details around us – birds, trees, the sky, shops and houses, other people. We make connections.’ Making these connections with our surroundings can lift our spirits.
An Essex University research team has shown that ‘green exercise’ – walking in a natural environment – markedly reduces stress levels, and enhances mood and self-esteem. So take the chance to reconnect with nature whenever you can. When you head for your local park, woodland, river or beach, keep your senses alert and tune in to what’s around you. The sky, for example. The Cloudspotter’s Guide by Gavin Pretor-Pinney tells you the difference between cirrocumulus (rippling, mackerel skies) and nimbostratus (rain on the way), or Will Cohu’s Out Of The Woods will help you distinguish ash trees from oaks and maples. You can even learn to find your own food.
Suzie, 59, from Surrey, joined one of Fergus the Forager’s courses to hunt for edible fungi, flora and seaweed, then cooked dinner over an open fire, using the foraged ingredients. ‘I was amazed at the number of edible plants growing in our hedgerows and woods, and learned how to distinguish tasty pickings from toxic lookalikes,’ she says.
4. Enhance your social life
‘The true charm of pedestrianism does not lie in the walking, or in the scenery, but in the talking,’ said Mark Twain. You can use a walk to chat and catch up with your partner, family and friends; enjoy the puff-and-pant challenge of climbing a hill together; or maybe join a walking group.
BBC sports presenter Clare Balding enjoys walking as a social activity. Her interviews for Radio 4’s Ramblings dispel the idea of rambling being a niche activity. ‘There are different sorts of walking and very different sorts of walkers,’ she says. ‘Not everyone has to wear a cagoule, gaiters and wield a stick.’
In her latest series, Balding walked with artists, musicians and dog owners. As she says, ‘The gym experience is not for everyone. Salvation comes in the form of a good old-fashioned walk.’ So, what are you waiting for? It’s hardly a new idea – but sometimes, the old ones are the best.
Graham Barker runs Walk East, a social enterprise to encourage more walking in east London.

How to Deal with Stress


Stress causes physical changes in the body designed to help you take on threats or difficulties.
You may notice that your heart pounds, your breathing quickens, your muscles tense and you start to sweat.
This is sometimes known as the 'fight or flight' response.
Once the threat or difficulty passes, these physical effects usually fade. But if you're constantly stressed, your body stays in a state of high alert and you may develop stress-related symptoms.

Symptoms of stress

Stress can affect how you feel emotionally, mentally and physically, and also how you behave.
How you may feel emotionally
How you may feel mentally
  • racing thoughts
  • constant worrying
  • difficulty concentrating 
  • difficulty making decisions
How you may feel physically
How you may behave
  • drinking or smoking more
  • snapping at people
  • avoiding things or people you are having problems with
Visit the Mind website for more signs of stress.

How to tackle stress

You can't always prevent stress, but there are lots of things you can do to manage stress better. You could:
Other things that may help:
  • share your problems with family or friends
  • make more time for your interests and hobbies
  • take a break or holiday
  • take some regular exercise and make sure you are eating healthily
  • make sure you are getting enough sleep (see tips on better sleep)
Read how 'workaholic' Arvind learned to deal with stress.

What causes stress?

Big life changes often create stress, even happy events like having a baby or planning a wedding.
Feeling that you aren't in control of events in your life – for example, if you are diagnosed with a serious illness or you get made redundant – can also cause stress.
Stress may be related to:
  • work – for example, unemployment, a high workload or retirement (see Beat stress at work)
  • family – for example, divorce, relationship difficulties or being a carer
  • housing – for example, moving house or problems with neighbours
  • personal issues – for example, coping with a serious illness, bereavement or financial problems
It's important to tackle the causes of stress in your life if you can. Avoiding problems rather than facing them can make things worse.
However, it's not always possible to change a stressful situation. You may need to accept there's nothing you can do about it and refocus your energies elsewhere. For example, if you're a carer, find ways to take breaks and do the things you enjoy.

When to see your GP about stress

If you've tried self-help techniques and they aren't working, see your GP. There are lots of other options open to you, such as guided self-help or cognitive behavioural therapy (CBT).
You may be able to attend a stress management course. Ask your GP or self-refer to your local psychological therapies (IAPT) services.

Resilience | How stress affects your body and brain



What does it really mean when we talk about stress? Clinical Physiologist Lead, Marcus Herbert, explains what's going on inside your body and your brain when stress strikes.
Stress is a very personal matter, in that it relies on our own perceptions. Put simply, stress is when a situation, pressure or change exceeds our coping abilities.
Take a rollercoaster ride for example. You might have two people that go on a rollercoaster together - one person may take genuine enjoyment from the experience. The other may experience genuine fear or anxiety. The rollercoaster itself doesn't change but our perceptions of it will differ. The same can be said for other stressful situations.
Of course, this example is just short-term stress, which in isolation may not cause us any harm at all. It's only when stress accumulates and exceeds our coping ability without adequate recovery that it becomes a problem. Stress is likely to occur after a build-up of life-change events that can be either positive or negative. They could include a business realignment, a promotion or even something enjoyable such as a holiday. What matters is that there is a change to you normal routine.
We all know that stress can make us feel overwhelmed, agitated and sometimes overwhelmed. The question is how does stress affect our body and our mind, and what can we do about it?

The physiological effects of stress

Within your central nervous system (your brain and spine) you have the autonomic system. This controls all of the processes that you do without thinking, such as breathing, digestion and your heart beat.
Within the autonomic system there are two systems of interest, which work in tandem with each other. These are the sympathetic system, known as the ‘fight or flight’ system, and the parasympathetic system, or the ‘rest and digest’ system.
The sympathetic system is responsible for increasing heart rate, increasing blood pressure and increasing blood sugar to help you to perform when stress hits. When you are stressed, this system triggers these necessary responses, and the function of your rest and digest system is reduced. The parasympathetic system is responsible for suppressing heart rate and bringing you back down to homeostasis.
Another hormone released when we are stressed is cortisol. Cortisol is an energising hormone which increases the level of blood sugar. This is great in the short term to provide energy to react quickly, but in the long term it can be bad for the immune system (as DHEA, which is also released by the adrenal glands and supports our immune system, can’t be released when cortisol is released).
Excess release of cortisol over a long period of time can also lead to increased risk of strokes and heart attacks. When blood sugar levels are raised it can lead to inflammation of artery walls. This damage can cause the immune system to respond, leading to a build-up of fatty deposits which can block the arteries. If some of this build up breaks away and is released into the bloodstream then it can block smaller arteries that lead into your brain or heart.
Stress can also limit our ability to think clearly. When we are stressed our ‘amygdala’ labels information coming into the brain as threatening and at the same time, limits activity in the cerebral cortex, the part of our brain that allows us to think strategically. This reduces our ability to make decisions, be sociable and take on new ideas and information. As a result, you may act in a way that you might later regret.

Coping strategies

So how can we combat these effects of stress and learn to develop resilience and perform better under pressure? When it comes to effective stress management, it's important to focus on the factors that are within your control.

1. Better sleep

Getting a good night’s sleep is important in reducing stress because when we are deprived of sleep, the amygdala becomes much more reactive and so will our minds and bodies. It’s also important to take regular breaks during the day to re-energise.

2. Gentle exercise

Low to moderate intensity exercise with a focus on muscle activation and breathing, like yoga can also have a positive effect on stress. That’s because it drives up the activation of the rest and digest system, rather than the fight or flight system which is activated during more intense exercise. Therefore, going for a gentle walk before bedtime can be more beneficial than a high intensity run. Furthermore, exercise can be a welcome distraction from the stressors in your life.

3. Don't look to substances to unwind

There are some lifestyle considerations that can help reduce stress too. Ingesting caffeine, alcohol and nicotine all increase the activation of the fight or flight system. So smoking and drinking wine are not the destressors that people think they are.
Taking these factors on board and modifying your behaviour can help you to improve your ability to prepare for, react to and recover from the stressors in your life, ultimately improving your resilience.
