In addition to cooling gadgets such as fans, humidifiers or ice machines, there are also a few basic things to consider to keep a room cool in summer:

Half of Germans feel most comfortable at a temperature of 19 to 21 degrees- In summer, this is hardly feasible without an expensive air conditioning unit. But even without a money- and energy-consuming air conditioning unit, you can lower the temperature in your home and even save money. Because what many people don't think about is that plugged-in appliances are always under power and electricity in turn produces heat. Appliances that are only used in the household for a few hours and run on standby the rest of the time should be unplugged, especially in summer.

Also be careful with appliances that generate extra heat: blow-drying your hair in summer, for example, generates unnecessary heat and consumes energy. It is therefore better to air-dry your hair, which not only reduces the heat in your home, but also saves time and money and is good for your hair too.

It's the same with the oven: of course you can't always do without the oven in summer, but you can still bake or cook more consciously. Just opening the oven door - to take a look at the contents - allows a lot of heat to escape: 20 percent of the heat is lost every time the oven door is opened. This not only makes the kitchen warmer - the loss of energy means you have to reheat, which in turn leads to higher energy costs.
