Stressed all the time? Your body could be paying the price

Chronic stress affects more than just emotions; it can have tangible impacts on the body. For South Africans, who already struggle with metabolic diseases like obesity, type 2 diabetes, and cardiovascular issues, managing stress may be vital for long-term health. According to the International Diabetes Federation, about 2.32 million South African adults were living with diabetes in 2024, making up 7.2% of the adult population.

Work-related stress is also prevalent, with Gallup reporting that 36% of South African employees felt significant stress the previous day.

When stress becomes chronic, it can disrupt normal physiological processes. One key hormone involved in the stress response is cortisol. High levels of cortisol over time can alter blood sugar regulation, decrease insulin sensitivity, and promote fat storage, particularly visceral fat around vital organs. This type of fat is metabolically active and linked to a higher risk of type 2 diabetes and heart disease.

The connection between stress and metabolic health is complex. Stress can lead to unhealthy habits such as poor eating, reduced physical activity, and poor sleep. These lifestyle changes can worsen metabolic conditions and create a vicious cycle where metabolic disorders, in turn, intensify stress responses. For instance, stress-related overeating can contribute to weight gain, which further elevates the risk of diabetes and cardiovascular issues.

The relationship is bidirectional: chronic health conditions can also amplify stress. Poor sleep, a common outcome of stress, can lead to decreased energy for exercise and difficulties maintaining a healthy diet. This creates a loop where stress affects sleep and behavior, and declining health adds more stress.

In South Africa, where workforce pressures include financial strain, job insecurity, and demanding workloads, stress is a significant issue. The 2025 Profmed Stress Index revealed that financial pressure and workplace challenges are major stressors for South African professionals. The survey also noted that stress can negatively impact health behaviors like exercise, sleep, and eating habits.

To address this, a holistic approach to health is necessary. Regular physical activity, adequate sleep, a balanced diet, avoiding smoking, and moderate alcohol consumption are crucial. Additionally, mindfulness practices and strong social support can aid in stress management. Heart Awareness Month serves as a reminder of the importance of understanding and mitigating the stress-metabolism link for long-term cardiovascular health.
