Why is it essential to test water temperature before applying it during a service?

Testing the water temperature before applying it during a service is crucial primarily to avoid discomfort or burns to the client. When water that is too hot is used, it can lead to physical harm, such as scalding or irritation of the skin, which not only causes immediate discomfort but can also result in longer-term skin issues. Ensuring that the water is at a comfortable, safe temperature promotes a positive experience for the client and maintains their trust in the service provider's professionalism and care. Proper temperature management is a key aspect of client safety and comfort in any service involving water use.
