Should We Really Heat to 19°C? Here’s the Ideal Temperature According to Experts
As the chilly months set in, it’s easy to reach for the thermostat and crank up the heat. But how warm should we really make our homes? Is 19°C (or 66°F) the right temperature, or is it too cold—or even too warm? Many people debate the ideal indoor temperature during the winter, and with rising energy costs and environmental concerns, it’s essential to find a balance between comfort, energy efficiency, and health. Here’s what experts recommend and why 19°C might or might not be the best target for your home.
The Common 19°C Debate
The idea that 19°C is the “ideal” indoor temperature has become popular in some parts of the world. It’s often cited as a comfortable, energy-efficient setting that keeps both your heating bills and environmental impact lower. But is this actually the ideal temperature, or is it a bit of a misconception? Let’s break it down based on expert advice.
What Experts Say About the Ideal Indoor Temperature
According to health and comfort experts, the “ideal” indoor temperature can vary based on a few different factors, including personal comfort, energy efficiency, and the specific activities you’re doing in your home. However, there are a few general guidelines:
- Comfortable Temperature Range: Most experts agree that the ideal indoor temperature during colder months is typically between 18°C to 21°C (64°F to 70°F). This range is usually comfortable for most people, balancing warmth and energy efficiency. Within this range:
- 18°C is considered comfortable for resting or sleeping.
- 19°C to 21°C tends to be more appropriate when you’re active at home, working, or moving around.
- Sleeping Temperature: When you’re asleep, your body temperature naturally drops. Experts suggest a cooler room temperature of around 16°C to 18°C (60°F to 64°F) is optimal for sleep. This cooler environment can promote better sleep quality and improve overall rest. 19°C might feel slightly warm for some during sleep, potentially affecting sleep quality if you prefer a cooler room.
- Energy Efficiency: From an energy efficiency standpoint, 19°C is often touted as a good compromise. Setting your thermostat to 19°C instead of warmer temperatures can reduce heating costs significantly, especially over the winter months. For every degree lower, you could save up to 3% on your heating bills, which adds up quickly over time. Additionally, lower indoor temperatures can help reduce the strain on your heating system and conserve energy.
- Health Considerations: Health experts emphasize that temperatures too low (below 18°C) can make some people vulnerable to cold-related health issues, especially the elderly or those with respiratory problems. On the other hand, consistently higher temperatures (over 21°C) can dry out the air, leading to dry skin, irritated sinuses, and dehydration. Maintaining a steady temperature around 19°C can strike a balance between comfort and maintaining a healthy environment.
