Stepping outside

Go outside for a few minutes, ideally somewhere with trees, grass or sky. Short time in nature lifts mood in studies, but most tested 10 minutes or more.

Short answer

Go outside for a few minutes. If you can, stand or sit where you can see trees, grass, water or open sky, and look at it rather than your phone. Brief time in nature reliably nudges mood up in studies. But most of those studies used 10 minutes or more, so a 4-minute version is an educated guess at a smaller dose.

How to do it

  1. Go out of the nearest door. A garden, a balcony, a courtyard, the pavement outside your building.
  2. Find something green or open if there’s any nearby: a tree, a patch of grass, a park bench, a view of the sky.
  3. Stand or sit still for a few minutes. You don’t need to walk. If you want to move, see A short walk.
  4. Look around on purpose. Notice the light, the weather, what’s moving. Leave the phone in your pocket.
  5. If you have 10 minutes, take them. That’s closer to what the research tested.

Can’t get outside? Open a window and look out at the furthest thing you can see. It’s not the same, but it’s better than nothing.

When to use it

  • When you’ve been indoors under artificial light for hours.
  • In the middle of a long day at a screen.
  • When you feel cooped up, restless or irritable.
  • First thing in the morning. For why daylight matters beyond a quick mood boost, see Daylight and time outdoors and sleepgood.now.

Evidence

A meta-analysis of 32 studies with 2,356 people found that contact with nature increased positive feelings by a moderate amount and reduced negative feelings by a smaller but consistent amount, compared with control conditions. The size of the boost varied with the type of nature exposure and how feelings were measured [1].

A review of 14 studies with college-age people, most of them in Japan, concluded that as little as 10 minutes of sitting or walking in nature improved measures of mental well-being compared with the same time in urban settings [2].

In an 8-week study, 36 city dwellers took “nature breaks” of at least 10 minutes when it suited them. A stress hormone dropped more than it normally would across the day. The best return for the time spent was between 20 and 30 minutes [3]. There was no separate control group; people were compared with their own daily patterns.

Rated Weak for this quick version. The case for time in nature lifting mood is reasonable, but the studies are mostly small and short, many used students, and almost none tested a few minutes outside on its own.

Try this week

Pick one break a day this week, like after lunch or mid-afternoon, and spend it outside instead of at your desk. Find the greenest spot within a minute of your door. Stay at least 4 minutes, longer if you can, and leave your phone in your pocket.
