It is important an adequate regulation of temperature in highly hot and cold months. It is advisable to keep home between 22°C and 25°C in summer and between 19°C and 21°C in winter during the day and between 15°C and 17°C at night. As humidity increases in summer, it may be necessary to reduce temperature to maintain the same wind chill. It is recommended to keep temperature at 25°C or even higher in the summer months. A difference of more than 7° C compared with outside temperature may be unhealthy, and any extra degree of temperature increases energy consumption over 8%. In winter, turn down the temperature level when you are at home. You can exercise at an adequate temperature to reduce the risks of cardiovascular disease, diabetes and also to lose weight. Wear warm clothes and try to have hot drinks from time to time.
