Homes can be kept cooler during a heatwave without relying on fans or air conditioning by closing curtains, blinds and shutters before temperatures peak, using reflective materials on windows, and opening windows and doors in the evening to create cross-ventilation. Residents are advised to concentrate cooling efforts on one or two rooms, avoid heat-producing kitchens and sun-facing rooms, and use fans only when occupied; placing a bowl of ice beneath a fan may provide additional cooling.

Natural yoghurt is made by fermenting milk with live bacterial cultures, while Greek yoghurt undergoes an additional straining process that removes much of the whey. This makes Greek yoghurt thicker and typically higher in protein, whereas natural yoghurt has a lighter consistency and milder taste. Both can form part of a balanced diet, with Greek yoghurt suited to dips, marinades and sauces and natural yoghurt commonly used in cereals, smoothies, puddings, baking and salad dressings.
