Kate Garraway gave Good Morning Britain viewers some handy heatwave hacks to help people get a better night's sleep - but she still struggled to sleep, despite taking her own advice.
She told GMB co-stars Adil Ray and Laura Tobin she slept terribly, struggling to get some rest because of the humid and "muggy" night.
