The Impact of Temperature and Humidity on Physiology

According to the research of physiologists, when the indoor temperature is too high, it will affect the human body's temperature regulation function, causing body temperature to rise, vasodilation, pulse acceleration, and heart rate acceleration due to poor heat dissipation. In winter, if the indoor temperature is often maintained at25"℃" is the symbol for Celsius temperature scale.以上，人就会感到神疲力乏、头晕脑涨、思维迟钝、记忆力差。同时，由于室内外温差悬殊，人体难以适应，容易患伤风感冒。如果室内温度过低，则会使人体代谢功能下降，脉搏、呼吸减慢，皮下血管收缩，皮肤过度紧张，呼吸道粘膜的抵抗力减弱，容易诱发呼吸道疾病。因此，科学家们把人对“cold tolerance”的下限温度和“heat tolerance”的上限温度，分别定为11"℃" is the symbol for Celsius temperature scale.and32"℃" is the symbol for Celsius temperature scale.。

At the same time, we should also pay attention to the humidity in the room. In summer, when the indoor humidity is too high, it will inhibit human heat dissipation, making people feel very hot and irritable. In winter, when the indoor humidity is high, it will accelerate heat conduction, making people feel cold and depressed. When the indoor humidity is too low, due to the large loss of water in the upper respiratory tract mucosa, people will feel dry mouth, tongue dry, even sore throat, hoarse voice and nasal bleeding, and are more prone to catch a cold. Therefore, experts believe that the upper limit value of relative humidity should not exceed80%The lower limit should not be lower than30%。

然而，人的体感并不单纯受气温或气湿两种因素的影响，而是两者综合作用的结果。通过实验测定，最宜人的室内温湿度是：冬天温度为20℃，相对湿度为40%；夏天温度为25℃，相对湿度为50%。18to25"℃" is the symbol for Celsius temperature scale.Humidity: 30%to80%Summer temperature is23to28"℃" is the symbol for Celsius temperature scale.Humidity: 30%to60%。在此范围内感到舒适的人占95%The above. In an indoor room with air conditioning, the room temperature is19to24"℃" is the symbol for Celsius temperature scale.Humidity: 40%to50%When it comes to the comfort of people, the temperature and humidity can have a significant impact on their thinking.activityThe most suitable room temperature for high work efficiency should be.18"℃" is the symbol for Celsius temperature scale.The humidity should be40%to60%At this time, people's mental state is good and their thinking is most agile.

Question markOperating Method

1. Push the battery door in the direction indicated by the machine's back, remove the battery separator, then replace the battery door, and the machine is ready to use.
2. Button Function: [MODE] Switches display mode between clock and alarm clock/sets current time, alarm, 12-hour or 24-hour format, date; [ADJ] Adjusts the value of the set item; [MEMORY] Displays the highest and lowest temperature and humidity values in memory/clears the highest and lowest temperature and humidity values in memory; [℃/℉] Switches temperature unit to ℃ (celsius) or ℉ (fahrenheit) display; [RESET] Clears all settings and memory values, returns to the initial state.
3. In the initial state, press [MODE] for 2 seconds, and the minute number of the current time begins to flash. Press [ADJ] to adjust the minute number. Press [MODE] continuously to set the "clock", "12/24", "month (M)", and "day (D)".
4. In the current clock mode (the two o'clock marks flash once per second), press [MODE] once to switch to the alarm mode (the two o'clock marks do not flash). At this time, pressing [ADJ] can switch the "alarm" function / "alarm" function on and off. Press [MODE] for 2 seconds to set the alarm time and simultaneously start the "alarm" function, (Vbcd symbols appear).
5. In the alarm mode, if no operation is performed, the current clock will automatically return after one minute. At this time, pressing [ADJ] once will switch to the calendar display, and after 3 seconds, it will automatically return to the current clock.

Press the MAX/MIN button to display the maximum value since the last time the temperature/humidity was cleared (CLEAR).

1. Press [MEMORY] to display the maximum (MAX) and minimum (MIN) temperature/humidity values of the memory, holding [MEMORY] for over 2 seconds will clear the maximum/minimum values of the memory.

• Question markNotes

1. Please press the [RESET] button once when you first use or change the battery (on the back of the machine).
2. If the machine experiences any problems, press the [RESET] button once.
3. Please return the used batteries to the government-designated location.
