What is the optimum temperature and humidity for the hotel?

According to the research of physiologists, when the indoor temperature is too high, it will affect people's body temperature regulation function. Due to poor heat dissipation, it will lead to higher body temperature, vasodilation, faster pulse and faster heart rate. In winter, if the indoor temperature is always above 25℃, people will be exhausted, dizzy, slow-thinking and poor memory. At the same time, due to the large temperature difference between indoor and outdoor, it is difficult for human body to adapt and it is easy to catch a cold. If the indoor temperature is too low, the metabolic function of the human body will be reduced, the pulse and breathing will slow down, the subcutaneous blood vessels will contract, the skin will be excessively tense, and the resistance of the respiratory mucosa will be weakened, which will easily induce respiratory diseases. Therefore, scientists set the lower limit temperature of "cold tolerance" and the upper limit temperature of "heat tolerance" as 1 1℃ and 32℃ respectively.

While paying attention to indoor temperature adjustment, we should also pay attention to indoor humidity. In summer, the indoor humidity is too high, which will inhibit the heat dissipation of the human body and make people feel very stuffy and irritable. Indoor humidity is high in winter, which will accelerate heat conduction and make people feel cold and depressed. When the indoor humidity is too low, people will feel thirsty, even sore throat, hoarse voice and nosebleeds. And it is easy to catch a cold because of the large loss of water in the upper respiratory mucosa. Therefore, experts believe that the upper limit of relative humidity should not exceed 80% and the lower limit should not be lower than 30%.

However, people's somatosensory perception is not simply affected by temperature or humidity, but the result of their joint action. The most comfortable indoor temperature and humidity are: 18 ~ 25℃ in winter and 30% ~ 80% in humidity; In summer, the temperature is 23-28℃ and the humidity is 30-60%. More than 95% people feel comfortable in this range. In an air-conditioned room, people will feel most comfortable when the room temperature is 19 to 24℃ and the humidity is 40% to 50%. Considering the influence of temperature and humidity on people's thinking activities, the most suitable room temperature should be 18℃ and humidity should be 40% to 60%. At this time, people have a good mental state, the most agile thinking and high work efficiency.
