But you and I have to work on events, in restaurants, small apartments and in the heat of the sun outdoor. Sometimes we have to work in concert halls under dusty wings with overheated and very dry air. Of course, the environment at the celebrations is always not ideal.
It would be great to humidify and cool the air in the room before work. It can be done with a regular ventilation in the cool and humid season of the year. Or we can use conditioners and humidifiers. Many professional performers measure the temperature and humidity of the air to adjust it before performing. It's time-consuming process and not every performer is ready for that. But if you have a desire, abilities and power, then it makes sens to take a thermometer and a hygrometer with yourself. In any case, if the room is stuffy and hot, airing or cooling the room will not hurt. It's even better to be able to humidify the air by: using humidifiers, boiling dry ice, a steam generator, or, at worst, a spray gun.
