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

In order to advance innovative Mathematics and Science teaching and learning, Science-for-the-Future from the University of the Free State’s (UFS) Faculty of Education hosted close to 100 Grade 10 Mathematics and Science achievers from 18 local secondary schools at the Boyden Observatory in Bloemfontein on 7 June 2017.
According to Dr Cobus van Breda, the Programme Director of Science-for-the-Future, the purpose of such events is also “to encourage learners to enter into science-related studies and careers, including the teaching profession, since we are in desperate need of good Maths and Science teachers in South Africa”.
The evening included contributions by two visiting National Science and Technology Forum (NSTF) award-winning presenters.
Prof Peter Dunsby from the Cosmology and Gravity Centre at the University of Cape Town gave the audience much to think about with his presentation titled ‘From the Big Bang to the Big Rip. Should we be afraid of the Dark Side of the Universe?’
Prof Jan Smit from the North-West University, on the other hand, explained basic Physics concepts using mostly household items. Mariette Erwee and Prof Matie Hoffman from the UFS concluded the evening with stargazing through the telescopes, as well as an open-air session on constellations.
