Arina Engelbrecht from Organisational Development and Employee Well-being believes physical activity has a number of benefits for one’s health, including stress relief.

Being physically active plays a big role in preventing the development of mental-health problems and in improving the quality of life of people experiencing mental-health problems.

Treatment for depression

Physical activity can be an alternative treatment for depression. It can be used as a stand-alone treatment or in combination with medication and/or psychological therapy. It promotes all kinds of changes in the brain, including neural growth, reduced inflammation, and new activity patterns are formed that promote feelings of calm and well-being. It releases endorphins – powerful chemicals in the brain that energise your spirit and make you feel good.  

Physical activity can be very effective in relieving stress. Research in adults has found that physically active individuals tend to have lower stress levels compared to individuals who are less active.  It also leads to improved sleep. When a person sleeps better and feels more rested, overall quality of life improves. They cope better with daily life stressors.

Reduce Alzheimer's risk

Regular physical activity can reduce your risk of developing Alzheimer's disease by up to 50%. It can also slow down further deterioration in those who have already started to develop cognitive problems.  It stimulates the brain’s ability to maintain old connections as well as to make new ones.

A study asked people to rate their mood immediately after periods of physical activity (e.g. going for a walk/run, cycling, doing housework) and periods of inactivity (e.g. reading a book or watching television). Researchers found that participants felt more content, more awake, and calmer after being physically active compared to after periods of inactivity.

In conclusion, people who are physically active feel a sense of well-being, feel more energetic throughout the day, sleep better at night, have sharper memories, and feel more relaxed and positive about themselves and their lives.

“Being physically active not only changes your body, it changes your mind,
attitude, and your mood.” – Arina Engelbrecht

The planet has more species than ever before, but humans are responsible for the biggest mass extinction of all times. This is according to Prof. Jo van As, Head of the Department of Zoology and Entomology. He was speaking at the launch of the book The Story of Life & the Environment: An African Perspective.

The book was published by Random House Struik in July 2012 and is a sister publication of The Story of Earth & Life by Prof. Bruce Rubidge, which was published in 2005.

The Story of Life & the Environment: An African Perspective took five years to complete. Prof. Van As was the compiling author, with Prof. Johann du Preez, Head of Plant Sciences at our university, Prof. Leslie Brown of Unisa and Prof. Nico Smit of the North-West University as co-writers.

Prof. Van As said, “No other species has destroyed the earth as we have done. Biological diversity disappears at the rate of mass extinction. The effects of human activities on the biological diversity is bigger that the extinction of the dinosaurs.”

He, however, added that The Story of Life & the Environment: An African Perspective does not sketch a doomsday scenario. It has also a message of hope. Prof. Van As said it was good to see progress in conservation and care for the environment. Trans-frontier parks the size of some countries are a good example of work in this regard.

Mr Stephen Johnson, chairperson of the board of Random House Struik, said at the launch that the publishing house was proud to be associated with the impressive book. The publication will be a touchstone for thoughtful readers for a long time. It will also remain a general book for the public and learners on the topic. The content and design was done in such a way that the publication will be relevant to all audiences.

The Afrikaans version of the book, Die Verhaal van Lewe en die Omgewing, will be published soon.
