South Africans under money pressure are not only losing sleep. Growing evidence shows the strain is settling into their bodies, with the lower back taking the worst of it.
The link between debt and back pain
A study in the journal BMC Public Health compared people under severe financial strain with the general population. The difference was stark. Back pain affected 80% of the financially strained group against 20% of everyone else, making heavily indebted people eleven times more likely to suffer from it.
The biology behind it is well documented. Ongoing stress keeps cortisol and adrenaline circulating in the body. Muscles stay tense, inflammation rises, and pain sensitivity increases. American pain specialists note that money worries most often surface as pain in the lower back, neck and shoulders.
A South African problem
Local numbers suggest the country is squarely in this territory. The 2025 DebtBusters Money-Stress Tracker reported that 70% of South Africans experience financial stress, and 73% of that group say it affects their health.
One place this pattern becomes visible is at the point where people finally replace their beds. Mr Mattress, a South African memory foam mattress company, surveys every customer at purchase. More than 1000 buyers completed the questionnaire over the past six months, and a consistent theme runs through the answers: financial pressure by day, an aching back by night.
“Nobody mentions thread counts. They mention pressure,” says founder Andries Taljaard. “What stands out is how long people wait. By the time they buy, the back pain has usually been building for months while they saved up. The economy delays the purchase, and the body pays the price in the meantime.”
Why the cycle matters
Researchers describe a loop that is hard to escape. Stress tightens the back. The painful back disrupts sleep. Poor sleep weakens the ability to cope, which raises stress further. Each turn of the cycle makes the next one worse.
Taljaard says the practical answer is to break the loop at the point a person can control. “Nobody fixes the economy from their bedroom. But sleep is the one recovery tool that keeps working night after night once the right support is under you. A foam mattress that holds the lower back properly removes one fight from the list, and South Africans need every win they can get right now.”
