Look after yourself

Nature prescription: 120 minutes a week

In a study of about 20,000 people in England, those who spent at least 2 hours a week in nature reported noticeably better health and wellbeing. It made no difference whether those 2 hours came in one go or in several shorter visits. In Istanbul, nature is closer than you think: a park, a grove, the shore or the seaside all count.

Nature in Istanbul

Where to this week?

You don’t need to go far; the park closest to your home counts too. A few suggestions:

European side

  • Belgrad Forest
  • Emirgan Grove
  • Yıldız Park
  • Maçka Park
  • Gülhane Park
  • Atatürk Urban Forest
  • Bebek–Rumelihisarı waterfront
  • Florya seafront

Asian side

  • Validebağ Grove
  • Fenerbahçe Park
  • Göztepe 60th Anniversary Park
  • Moda seafront
  • Büyük Çamlıca Hill
  • Kuzguncuk–Beylerbeyi waterfront
  • Polonezköy
  • Princes’ Islands

Even seeing trees from a window

In a famous study published in Science in 1984, researchers looked at the records of patients who had had gallbladder surgery. They compared 23 patients whose window looked out on trees with 23 similar patients whose window faced a brick wall.

  • Those who could see trees stayed in hospital for less time: 7.96 days on average versus 8.70 days.
  • They needed fewer strong painkillers.
  • Nurses’ notes contained fewer negative comments about them.
  • It was a small study, but it inspired hospital designers to make room for nature.

The awe walk

52 healthy older adults took a 15-minute walk once a week for 8 weeks. In the group asked to pay attention to a feeling of “awe” as they walked (that sense of wonder in the face of something far bigger than yourself), daily distress fell and emotions such as compassion and gratitude increased. In the photos they took on their walks, they gradually gave less space to themselves and more to the scenery, and their smiles became more noticeable.

1

Put your phone in your pocket

Taking photos is fine, but don’t walk along staring at the screen.

2

Notice what is vast

The breadth of the sea, the sky, the trunk of an old plane tree: look at things bigger than you.

3

See the small things too

The veins of a leaf, the moss between the stones, the flight of the gulls.

4

Something new each time

Choose a different route or time of day; even familiar places can surprise you with new details.

Frequently asked questions

Do I have to go to a forest or the countryside?

No. In the research, visits to open green and blue spaces such as city parks, groves, beaches and the countryside were all counted together. The park in your neighbourhood or the seafront works too.

Do I need to exercise?

No. Sitting or walking slowly in nature counts too. In the study that measured the stress hormone, participants were specifically asked not to do brisk exercise or use their phones. If you do walk, you get the benefits of movement as well.

Do I have to do the 120 minutes all at once?

No need. In the research, it made no difference whether the weekly time was made up of one long visit or several short ones. For example, 30 minutes on 4 days works too.

I can’t leave the house. What can I do?

Even seeing greenery from a window has been linked to better recovery. Open the curtains, sit near a window if you can, and grow plants on your balcony or windowsill. If you find it hard to get out of the house, physiotherapy can help you walk with confidence again.
