At first glance, placing a bowl of water in the fridge might seem pointless. However, this seemingly meaningless action can help your refrigerator operate more efficiently — and ultimately help you save on electricity bills.

Here’s how this small change makes a big impact:

Why Put a Bowl of Water in the Fridge?

Refrigerators are designed to maintain a stable internal temperature. But when the fridge is nearly empty, there's more empty space for warm air to circulate whenever the door is opened. This forces the fridge to work harder to maintain its cool environment, consuming more energy.

By adding a bowl of water, you help fill up some of that space. Water holds cold temperatures well and acts as a thermal stabilizer, helping reduce temperature fluctuations inside the fridge.

The Science Behind It

• Water has high heat capacity, meaning it can absorb and retain cold better than air.

• When placed in the fridge, the water cools and stays cold, reducing the workload of the cooling system.

• This helps prevent the compressor from turning on and off frequently — which is one of the major contributors to higher energy consumption.

 Tips to Make It Work Better

• Use a ceramic or glass bowl, which retains cold better than plastic.

• Place the bowl on the middle or bottom shelf, where airflow is stable.

• Don’t block vents or overfill the fridge — the goal is to support efficiency, not reduce airflow.
