The 120-Minute Rule: Why Time in Nature Is Good for You

August 29, 2026 · 4 min read · Sleep & Recovery

Most of us spend the vast majority of our time indoors. A large study suggests there may be a simple, measurable target for getting back outside.

The study

In 2019, Mathew White and colleagues analysed data from almost 20,000 adults in England (White et al., 2019). Participants reported how much time they had spent in natural settings — parks, woodland, beaches and countryside — over the previous week, along with their health and wellbeing.

120 minweekly threshold for benefits

200–300minutes a week, where benefits peaked

White et al., 2019

The findings

Weekly time in nature	Association with health and wellbeing
None	Baseline
Under 120 minutes	No clear benefit
120 minutes or more	Significantly higher odds of reporting good health and high wellbeing
200–300 minutes	Benefits appeared to peak

Two details make this practical:

It didn’t matter how the 120 minutes was split. One long weekend walk or several short visits worked similarly.
The association held across age groups, occupations and ethnic groups, and for people with long-term health conditions.

This was observational research, so it can’t prove that nature causes better health — healthier people might simply get outside more. But it gives a clear, achievable target.

How to get your 120 minutes

That’s about 17 minutes a day, or two one-hour outings a week.

Approach	Weekly total
17-minute park walk every day	~120 min
Lunch outside 3× (20 min) + weekend hike (60 min)	120 min
Two 1-hour weekend outings	120 min
Walking route through a park on 5 commutes (15 min each way)	150 min

Ideas:

Walk through a park on your commute instead of along the main road.
Take lunch outside two or three times a week.
Do your weekend workout outdoors — a run, a hike, a park bodyweight session.
Take walking meetings in green spaces.
Plan one longer outing each weekend: a hike, a beach walk, a forest trail.

Double up with movement

Combining nature with activity also helps you towards the WHO’s recommendation of at least 150 minutes of moderate activity a week (Bull et al., 2020). A brisk 30-minute walk in a park, four times a week, ticks both boxes.

Week plan	Nature minutes	Activity minutes
4 × 30-min brisk park walk	120	120
+ 1 × 45-min weekend hike	45	45
Total	165	165

No big park nearby?

Urban green space counts. Tree-lined streets, community gardens, riversides and small parks all qualify as natural settings in the study’s terms. “Blue spaces” — beaches, lakes and rivers — counted too.

Make the most of your time outside

Leave the headphones off for some of it and notice what you can see and hear.
Go in daylight when you can — morning light also helps anchor your body clock.
Bring someone along — combining nature with social time is a bonus.
Dress for the weather so it’s not a reason to stay in.

Winter and bad weather

Short days and rain make this harder. Lower the bar: 10-minute walks around the block at lunchtime still count, and a waterproof jacket opens up far more days. Save longer outings for the brighter weekend days.

Why might nature help?

Researchers have suggested several explanations: time outdoors often comes with physical activity, less noise and air pollution, more daylight, social time, and a break from screens and work. The study wasn’t designed to tell these apart, and it’s likely several work together. You don’t need to know which one matters to benefit: getting outside covers them all.

A 4-week plan to build the habit

Week	Target	How
1	60 minutes	Two 30-minute walks in a park
2	90 minutes	Add outdoor lunch breaks on two days
3	120 minutes	Add a longer weekend outing
4	120+ minutes	Make it routine: same days, same places

Track your minutes on paper or in your phone for the first month. Once it’s routine, you won’t need to.

Getting outside with family

Make weekend outings an activity: a picnic, a nature trail, a bike ride.
Let children choose the route or set a challenge, like spotting five types of tree.
Walk or cycle to school or the shops when possible.
Swap one indoor activity a week for an outdoor one.

FAQ

Does my garden count? Time in natural settings near home may help, but the study focused on visits to places like parks, woodland and beaches. A walk to a local park is an easy upgrade.

What about exercising in a gym near a window? Good for fitness, but it’s not the same as being outside.

The bottom line

Aim for at least two hours a week in green or blue spaces, split however you like. Pair it with walking or training and you’re improving several habits at once.
