Ever notice how even the shade feels hot? That’s because our infrastructure wasn’t built for a heatwave. Dark tarmac and grey concrete soak up that weak northern sun like it’s going out of style.
They then radiate that stored heat back at you at night. So you lie there, sweating into your pillow at 11 p.m., wondering why your brain feels like porridge.
