A new study conducted by the University of Georgia, showed a ten minute walk up the stairs and down much much stronger than the drinks with caffeine, reports The Daily Mail.
The study involved students suffering from chronic lack of sleep. They slept less than 6.5 hours a day. On different days the participants took capsules containing caffeine or placebo, or slowly walked the stairs for ten minutes. Women held approximately 30 floors.
Also the participants performed cognitive tests and filled out questionnaires designed to assess their well-being. After the walk participants were more cheerful than after ingestion of capsules with caffeine.
Exercise and caffeine almost did not effect on memory and concentration.
However, walking the stairs increases the working motivation, the researchers say.
Earlier scientists from the University of Canberra (Australia) called the way to keep a clear mind in old age.
To save people over the age of 50 cognitive abilities (e.g. attention and memory) are sufficient, according to the authors, the weekly physical education lessons with a total duration of about 45 minutes.
