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 impact of personal care products on water resources in the Free State

Water is of the utmost importance in personal hygiene. Most people can hardly have a day go by without taking a shower in the morning and at night. However, it is this very habit that is increasingly polluting the water resources in South Africa.
Contaminants found in pharmaceutical and personal care products have been accumulating in water masses in recent years. These contaminants especially refer to hormones in medication, as well as colouring agents and fragrances used in soap, shampoo and body lotions.
“Little information and data are available on the prevalence of these contaminants, and on how high the level of pollution really is,” says Jou-an Chen, researcher in the Department of Microbial, Biochemical and Food Biotechnology at the UFS.
Her research particularly focuses on the prevalence and impact of those contaminants.
“Because these substances have not been properly investigated, we are not sure how widely it occurs and whether it is harmful to the environment. It was precisely the lack of information that has inspired me to investigate further.”
“If we could identify the contaminants and what it is doing to the environment, it could make a valuable contribution to directives on water quality standards.”
