Britain's National Trust is distributing away bottles of fresh air with a view to lift London city workers out of their stressed-out states.

The air, which was accumulated from seaside and rural areas around the UK, is reported to come in several scents, including the seaside smell of Townend, and the lakeside aroma of Windermere in Cumbria.

In addition, the scents include essence of Townend on the shores of Lake Windermere, the grassy scent of Stourhead in Wiltshire and the woodland aroma of Box Hill, Surrey.

"With most of us living in an urban environment and having little time to escape to the great outdoors, we thought it was about time the National Trust shared just a fraction of our copious amounts of fresh air with the nation," quotes, Andrew McLaughlin, National Trust head of communications.

The figures claims that nearly 74% of the UK workers experience stress on a daily basis, however, 70 per cent post that escaping from the city makes them feel instantly relaxed, according to a National Trust study.

The National Trust fresh air has been captured in environmentally-friendly British-made recycled glass jars which can be re-used for jams, preserves or capturing your own locally-sourced fresh air.
