With winter just around the corner and temperatures dropping, many are wondering what the ideal temperature is to keep the house warm without causing a significant increase in the electricity bill. A recent study carried out in the United Kingdom, involving 2 thousand people, seems to have the answer. The conclusion is clear: 19.5°C is the recommended temperature for a comfortable and energy-efficient environment.
Although some may consider this value a bit cold, the World Health Organization () reinforces that this is a safe recommendation. In fact, the entity even suggests a slightly lower temperature: 18°C. “Internal temperatures in homes must be high enough to protect residents from the harmful effects of the cold on their health,” says the WHO. For the majority of the population in temperate climates, keeping the home at 18°C during winter is safe and balanced, providing effective protection against the risks of cold weather.
However, the WHO highlights that not everyone benefits from keeping the environment in this thermal range. “A minimum internal temperature above 18°C may be necessary for vulnerable groups, including the elderly, children and people with chronic illnesses, especially cardiorespiratory illnesses,” highlights the organization. In these cases, the recommendation is to adjust the thermostat to a slightly higher temperature to ensure well-being and reduce the risk of cold-related health problems.
In the European context, where energy costs are a growing concern, balancing comfort and energy efficiency is essential. In addition to avoiding overloads on the heating system, maintaining the environment at around 19°C can result in considerable cost savings, while promoting a safe and welcoming environment for everyone.
This rational approach to home heating reflects a compromise between health, well-being and family economics, which can help minimize the impact of winter on energy bills without sacrificing comfort, keeping the home at a balanced temperature.
