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

INORG2009, the biennial conference of the South African Chemical Institute (SACI), was recently held on the Main Campus of the University of the Free State (UFS) in Bloemfontein. The conference, co-sponsored by the Royal Society of Chemistry: Dalton Division in the UK was attended by some 165 delegates from more than 40 different institutions and 14 countries. The conference focused on pure and applied aspects of inorganic chemistry with industrial (e.g. homogeneous catalysis, separation technology, hydrogen storage, etc.), bio-inorganic and medical and environmental relevance. From the left are: Prof. Jannie Swarts, Department of Chemistry at the UFS and member of the organising committee and plenary lecturer at the conference; Prof. André Roodt, Chairperson of the Department of Chemistry at the UFS and Chairperson of the organising and scientific committees of INORG2009; Prof. Jan Boeyens, University of Pretoria and plenary lecturer; Dr Jaco Erasmus, Delta EMD and session chairperson; Prof. Roger Alberto, University of Zürich, Switzerland and plenary lecturer; Prof. Peter Tasker, University of Edinburgh, Scotland, co-Chairperson of the organising committee and plenary lecturer; and Prof. Peter Comba, University of Heidelberg, Germany and plenary lecturer.
