By the numbers

What studies say about nature, water and the mind.

Nature & mind

120 mina week in nature was linked with better reported health and wellbeing in a study of 19,806 adults in England.
35studies were included in a 2017 review of blue spaces like lakes, rivers and the sea. Many linked more time near water with better mental wellbeing.
8studies were pooled in a 2019 review of forest bathing. Stress hormone levels were lower after forest time in the short term.
36studies on natural sounds were reviewed in 2021. Sounds like water and birdsong were linked with less stress and better mood.

Access & fairness

100 millionpeople in the U.S., including 28 million children, do not have a quality park within a 10-minute walk of home (Trust for Public Land).
1 kmUrban adults in England living within about 1 km of the coast reported better mental health. The link was clearest in the lowest-income households.
4,960adults in England took part in a study showing that feeling connected to nature mattered for wellbeing, beyond how often people visited.

Green, blue and wide-open spaces

The kinds of natural places researchers study.

Researchers often sort natural places into “green spaces” (parks, forests, fields, gardens) and “blue spaces” (coasts, lakes, rivers, even fountains). Mountains, deserts, prairies and big skies are open spaces that many people find just as powerful.

🌳 Green spacesForests, parks, fields, gardens and tree-lined streets.
Read more

Green spaces can be wild or very ordinary. A city park, a school field or a cemetery with old trees all count. A large study in England found links with better wellbeing at about two hours a week in nature, whether in one visit or several short ones.

For simple ways to add everyday green time, see Nature & the outdoors.
🌊 Blue spacesCoasts, lakes, rivers, ponds, canals and fountains.
Read more

A review of 35 studies found fairly consistent links between more time near water and better mental health and wellbeing. People near water also tended to be more physically active.

The links with physical health were less clear. The authors said more long-term studies are needed.

⛰️ Mountains and high placesBig views that can make everyday worries look smaller.
Read more

Standing somewhere high and looking out can bring a feeling of awe: the sense of being in the presence of something vast. Awe is one of the reasons people describe mountains as restoring.

You don’t need a summit. A hill in a park, a rooftop or a bridge with a long view can give the same “bigger picture” feeling.
🌅 Deserts, prairies and big skiesWide, quiet places with long horizons.
Read more

Open landscapes give the eyes somewhere far away to rest. Sunrises, sunsets, storms rolling in and starry nights are moments of awe that many people treasure.

In one study, older adults who looked for awe on short weekly walks reported more joy and less daily distress over eight weeks.

Every place counts. The “best” natural space is the one you can actually get to and enjoy.

Why might nature calm us?

The main ideas researchers use to explain it.

Nobody knows the full answer yet. Researchers have a few main ideas, and they likely work together. Most studies show links rather than proof, so it’s fair to call these good ideas, not settled facts.

🫀 A calmer stress responseNatural scenes may help the body settle after stress.
Read more

One idea is that calm natural scenes help the body switch out of “alert” mode. In a review of forest bathing studies, levels of the stress hormone cortisol were lower after time in a forest than after time in a city, at least in the short term.

Lower stress hormones for an hour or two is a real effect, but it’s not the same as curing stress or illness.
🍃 Rest for tired attentionNature holds your attention gently, so focus can recover.
Read more

Another idea, called attention restoration, is that screens and traffic demand hard, effortful focus. Leaves, clouds and water draw attention softly, which may let the “effort” part of the mind rest.

In a small Stanford study, a 90-minute walk in a green area reduced brooding, repetitive thinking. The same walk along a busy road did not.

🪟 A view can matterEven looking at trees may help.
Read more

In a well-known 1984 study, hospital patients recovering from surgery whose windows looked out on trees had shorter stays and fewer negative notes from nurses than patients whose window faced a brick wall.

It was a small study of 46 patients using past records, so it shows a link, not proof. Still, it changed how many hospitals think about windows and gardens.

✨ Awe and a “small self”Feeling small next to something vast can feel freeing.
Read more

In an eight-week study, older adults who took short “awe walks” took selfies that showed more of the scenery and less of themselves over time. They also reported more joy and less daily distress than people on ordinary walks.

The study didn’t find changes in anxiety or depression scores, and it was small. But it suggests awe can lift everyday mood and help people feel connected.

Forests and forest bathing: what’s known

Going deeper than the basics, with honest limits.

Forest bathing, or shinrin-yoku, means spending slow, quiet time in a forest, walking or simply resting and taking in the air. Nature & the outdoors has a simple 20-minute forest walk. This section looks at what the research really shows.

🔬 What happens in the bodyShort-term drops in a stress hormone.
Read more

A 2019 review screened 971 articles and pooled 8 studies on cortisol. Forest time was linked with lower cortisol than city time, in the short term.

An earlier review of 20 studies found short-term drops in low mood and anxiety after forest bathing and nature therapy.

🎈 The “looking forward” effectSome of the calm may start before you arrive.
Read more

In some studies, people’s cortisol was already lower right before their forest session started. The review authors said expectation, a kind of placebo effect, may play a real part.

That’s not a bad thing. Planning a nature outing you look forward to may be part of what helps.
❓ What isn’t known yetStrong claims online often go beyond the evidence.
Read more

The reviews are clear that studies are few, often small, and mostly measure short-term effects. Their authors call for larger, longer studies in more countries.

Be wary of claims that forest time…

  • Can replace care from a clinical provider
  • Cures anxiety, depression or physical illness
  • Only works with a paid guide or special program
  • Works the same for everyone
Forest time is a lovely way to care for yourself. It works best alongside, not instead of, other support.
🪵 A sit spotReturn to the same quiet spot again and again.
Read more

A sit spot is one place outdoors you visit often, even for ten minutes. Over weeks you start noticing small changes: a new bird, the light shifting with the seasons. Many people find it deepens their sense of belonging to a place.

Try it

  1. Pick a spot you can reach easily, like a bench, a tree or a step.
  2. Sit for 10 minutes without your phone in your hand.
  3. Notice what has changed since last time.
  4. Write one line about it when you get home.

Coasts, lakes and rivers

What research says about living and moving near water.

Water seems to have its own pull. Many people seek out a river path, a lake or the sea when they need to think. Research on “blue spaces” has grown quickly in the last decade.

🐚 Living near the coastA link with better mental health, especially for lower-income families.
Read more

A study of more than 25,000 urban adults in England found that living within about 1 km of the coast was linked with better mental health than living more than 50 km away.

When the researchers split people by income, the link showed up only in the lowest-income households. They suggested coasts may help narrow health gaps. The study can’t say what causes the link.

🚶‍♀️ Moving near waterGreen exercise plus water may give an extra lift.
Read more

A pooled analysis of 10 UK studies found that being active in nature improved mood and self-esteem. Green places that included water gave a bigger boost.

The biggest jump in self-esteem came in the first five minutes, so a short walk by a river still counts.

🧒 Growing up by waterChildhood time near water is linked with adult wellbeing.
Read more

In a survey of 15,743 adults in 18 countries, people who spent more time near water as children reported better wellbeing as adults.

Puddle-jumping, a trip to a pond, or skipping stones at a creek can all be part of a child’s blue-space time.
🛟 Safe around waterEnjoy water with care.

Simple habits

  • Check weather, tides and currents first
  • Go with someone, especially in open water
  • Keep children within arm’s reach near water
  • Wear a life jacket on boats and paddleboards

Mountains, big views and awe

How to look for awe close to home.

Awe is the feeling you get in front of something vast that you can’t quite take in: a mountain range, a canyon, a sky full of stars. You don’t need to travel far to find it.

Take a 15-minute awe walk

  1. Choose a route with some open sky or a view, even a city street.
  2. Put your phone away except for one photo.
  3. Look for things that are vast (sky, hills, tall trees) or detailed (a spider web, frost patterns).
  4. Pause and take in one of them for a full minute.
  5. Notice how you feel compared with when you started.
📷 What the awe-walk study foundMore joy, less daily distress.
Read more

Sixty healthy older adults took weekly 15-minute walks for eight weeks. Those asked to look for awe reported more joy and kindness-related feelings on their walks and less distress in daily life.

Their smiles in selfies also grew bigger over time. The study was small and short, so it’s a hint rather than proof.

🌌 Awe close to homeEveryday places can hold big moments.

Ideas

  • A full moon rising over rooftops
  • A thunderstorm watched from a safe window
  • An old, huge tree in a park
  • Clouds at sunset
  • Stars on a clear night away from streetlights
🥾 Going higherTrails and summits take more planning.
Read more

Mountain weather can change fast, and trails can be harder than they look. Start small, go with others, and tell someone your plan.

Hiking, camping & outdoor adventure covers awe on the trail, planning and safety in more depth.

Nature through a window, a speaker or a screen

When you can’t get out, nature can still come in.

Not everyone can get outside easily. Illness, disability, work, weather or safety can all get in the way. Research suggests some of nature’s calm can reach you through views, sounds and even video, though being there in person seems to help most.

🐦 Natural soundsWater and birdsong were linked with calm and better mood.
Read more

A 2021 review of 36 studies found natural sounds were linked with less stress and annoyance, better mood and better thinking. Water sounds were most linked with mood and focus, and birdsong with easing stress.

Open a window in the morning to hear birds, or play a recording of a stream while you wind down.
🪟 A window viewTrees, sky or a garden outside your window.
Read more

The hospital window study found patients with a tree view did better than those facing a wall.

Make the most of a window

  • Move your chair or desk to face outside
  • Put a bird feeder where you can see it, if allowed
  • Keep a plant on the sill
  • Take a two-minute “look out” break each hour
🥽 Nature on a screenHelpful, but not quite the same as the real thing.
Read more

In one experiment, six minutes outdoors and six minutes of a 360-degree nature video both felt more restoring than an indoor room. But only the real outdoors lifted positive mood.

Nature videos can be a good stand-in on days you’re stuck inside. When you can, the real thing seems to do a little more.

Feeling connected, not just visiting

How you relate to nature may matter as much as how often you go.

A study of 4,960 adults in England looked at both time in nature and “nature connectedness”: feeling that you are part of the natural world. Connectedness was linked with wellbeing and caring for nature, over and above how often people visited.

The authors suggested that the kind of experience matters, not just the number of visits. Noticing, feeling and caring seem to be part of it. The study shows links, not proof of cause.

Feel bark, smell rain on warm ground, listen for wind in the trees. Using your senses turns a walk into an experience.

Grounding & calming skills has more ways to use your senses to settle.
🧤 Care for a placeLooking after nature can deepen your bond with it.
Read more

In the England study, people who felt connected to nature were also more likely to do things that help it, like recycling and conservation.

Ideas

  • Join a park or beach clean-up
  • Plant something for bees or birds
  • Learn the names of five local trees or birds
  • Pick up three pieces of litter on your walk

Not everyone has a park nearby

Access to nature is not shared equally, and that’s not your fault.

The Trust for Public Land estimates that 100 million people in the U.S., including 28 million children, don’t have a quality park within a 10-minute walk of home.

Cost, transport, time, safety and not feeling welcome can all keep people from natural places. The England coastal study suggests nature may matter most for people with the fewest resources.

🌿 Nearby nature countsSmall, close places add up.

Look for

  • A churchyard or cemetery with trees
  • A college campus
  • A library garden or courtyard
  • A riverside, canal or rail-trail path
  • Street trees on a quieter route
🚌 Getting thereTransport and cost can be real barriers.

Ideas that can help

  • Ask your city or county parks department about free events and shuttles
  • Check for free entry days at state and national parks
  • Go with a group that shares rides
  • Libraries in some areas lend park passes
🤝 Feeling welcomeEveryone belongs in nature.
Read more

Some people feel out of place in parks or on trails because of how they look, their body, their disability or their background. That feeling is real, and it’s not a sign you don’t belong.

Hiking, camping & outdoor adventure has a section on feeling like you belong outdoors, including groups led by and for many communities.

How community helps

Nature shared with others, and caring for places together.

The CDC suggests spending time with others in nature, joining a community garden and volunteering as ways to build connection.

🏞️ Friends of the parkLocal groups that care for parks, rivers and trails.
Read more

Many parks and waterways have volunteer groups that plant trees, clear trails or remove litter. It’s nature time, movement and new people in one.

🔭 Citizen scienceCount birds, butterflies or stars with others.
Read more

Bird counts, butterfly surveys and night-sky watches invite anyone to help scientists by noticing nature. It gives your walks a purpose and connects you with others who care.

👨‍👩‍👧 Nature with familyShare the places you love across generations.
Read more

Children who grow up with more green space and time near water tend to have better mental health and wellbeing later on. Sharing nature with kids is a gift that lasts.

If climate change or damage to places you love weighs on you, Climate anxiety & eco-grief has ways to cope and connect with others.

When and where to get help

Nature helps, and sometimes you need more support too.

Time in nature is a good way to care for yourself, but it isn’t a treatment on its own. If you’re struggling, reaching out is a sign of strength.

Talk to your clinical provider or a therapist if…

  • Low mood, worry or stress lasts for weeks
  • Even things you used to enjoy, like being outdoors, don’t help anymore
  • It’s affecting your sleep, eating, work, school or relationships
  • You’re having thoughts of hurting yourself
