11 Summer Cooling Foods That Beat Air Conditioning

8. Buttermilk (Chaas) — Traditional Digestive Cooler

Buttermilk, known as chaas in many Indian homes, is a thin, seasoned yogurt drink that cools and replenishes fluids. It’s made by whisking plain yogurt with water until smooth, then adding salt, roasted cumin, and sometimes chopped coriander or mint. Because it’s fermented, buttermilk supports gut comfort and provides a light source of electrolytes. Serve it chilled in a steel tumbler for an authentic touch and better temperature retention. Buttermilk is often served with lunch to counteract hot, spicy dishes and to avoid sluggishness later in the day. In North America you can make it easily with store-bought plain yogurt or find bottled versions in South Asian grocery sections. Drinking a glass of chaas after a heavy meal keeps the digestive system calm and helps you stay comfortable without relying solely on air conditioning for immediate relief.
