Remember in this cold weather the temperature in your dance studio is important so that your dancers do their best.
To make sure that dancers can work efficiently and safely, the temperature of a dance studio should be around 18° to 24° degrees Celsius. An ideal temperature would be around 20°-21° degrees Celsius. This will help dancers to avoid either overheating or not being able to warm-up and stay warm efficiently, both of which can contribute to ill effects and injury.
Make sure that all your dancers keep their warm up clothes on longer in this cold weather so that muscles can be fully warm.
