Air conditioning is a sleep saviour when heatwaves have transformed your bedroom into an oven, but it could be the reason why you keep waking up at 3 a.m. This year, research has found that air conditioners can reduce indoor air quality, and now a doctor is warning that the reliance on AC can negatively impact sleep.
"Sleep is critical for recovery and repair, so anything that impairs respiratory comfort can interfere with the body's ability to fully recover overnight," says Dr Dale Christensen, Chief Science Officer for Climatic Health and Adjunct Associate Professor of Medicine at Duke University Medical Center.
