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

Unconventional oil and gas extraction – study for Water Research Commission reveals possible impacts

The Centre for Environmental Management (CEM) at the University of the Free State (UFS) recently completed a three-year project for the Water Research Commission. The purpose was to develop an interactive vulnerability map and monitoring framework for unconventional oil and gas extraction (final report still to be published).

Due to the complexity of this field, a number of participants across different disciplines and universities were involved in this trans-disciplinary study. Contributors included the Departments of Sociology, Physics and Mathematical Statistics from the UFS, the University of Pretoria Natural Hazard Centre, Africa, as well as the Institute of Marine and Environmental Law from the University of Cape Town.

Unconventional oil and gas extraction, its related impacts and the management of this activity to ensure environmental protection, is a controversial issue in many countries worldwide. Since the extraction of oil and gas using unconventional techniques is an unprecedented activity in South Africa, the project focused on understanding this extraction process as well as hydraulic fracturing and identifying possible environmental and socio-economic impacts associated with this activity in the South African context. An understanding of the possible impacts could aid government during the development of policy aimed at protecting the environment.

The researchers subsequently identified indicators to develop an interactive vulnerability map for unconventional oil and gas in South Africa. The vulnerability map focuses on specific mapping themes, which include surface water, groundwater, vegetation, seismicity and socio-economics. In addition, the map provides information on the vulnerability of the specified mapping themes to unconventional gas extraction on a regional scale. This map is intended as a reconnaissance tool to inform decision-makers on areas where additional detail field work and assessments may be required. It can also be used during Environmental Impact Assessments and determining licensing conditions.

Lastly, a monitoring framework was developed, which describes monitoring requirements for specific entities – surface water, groundwater, vegetation, seismicity and socio-economics – for the different phases of unconventional oil and gas extraction. Such monitoring is an important part of environmental protection. It is especially important for South Africa to perform baseline monitoring before exploration starts to ensure that we will have reference conditions to identify what impact oil and gas extraction activities has on the biophysical and socio-economic environments.
