Generally, the humidity is about 40-60%, and the human body is more comfortable. If the humidity is too low, the human body will feel dry, while if the humidity is higher than 65%, germs will multiply on the surface of the human body. The amount of hormone secreted by the pineal gland in the human body will increase, which will lead to a decrease in the concentration of thyroxine and adrenaline, and the cells will be lazy, and the human body will be listless and sluggish.

The humidity is 70%. Humidity is expressed in percentages, and there is no unit of humidity.

Humidity is the amount of moisture in a certain volume of air at a certain temperature, which is the physical quantity of the dryness of the atmosphere, that is, the dryness and wetness of the air; Commonly used are absolute humidity, loudness humidity, comparative humidity, mixing ratio, etc.; Among them, the most commonly used in our life is relative humidity, which is the percentage of the ratio of the actual water vapor pressure in the air to the saturated water vapor pressure at the temperature at that time, and it is an integer, so this relative humidity is 70%.
-
The relative humidity varies greatly in summer, it can reach 80 to 90 after rain and when it rains quickly, and it does not rain for many days in a row, only 60%.
-
Since it has been said, the humidity is 70 percent, that is 70 percent.
-
Isn't it all written on it, the humidity is 70%, and there is no other result.
-
The temperature is 34 degrees Celsius, the humidity is 70%, it is a very hot environment, I don't know what environment you are talking about, is it a laboratory or a place? What the humidity should be should also depend on the requirements of the environment.
-
This all says that if the humidity is 70%, then it should be 70%.
-
The humidity is 70%, isn't it already written, and there is no necessary connection with the previous temperature.
-
You've done it yourself, the temperature is 34 degrees, the humidity is 70%.
-
That is, 34 70% is a value, that is, a state of humidity, in many cases, the reason why humidity is not manifested is because it is still affected by many factors in the air, so it will be roughly presented in the form of percentages.
-
This should be inaccurate. If the indoor temperature is heated, it is generally around 25 degrees Celsius, and the humidity is generally between 40 and 60.
Comparison table of temperature and humidity meter + principle of hygrometer - humidity: In the measurement law, humidity is defined as "the amount of the state of the object". The humidity referred to in daily life is relative humidity, which is indicated by rh.
This is the percentage of the amount of water vapor (water vapor pressure) contained in a gas (usually in air) and the amount of saturated water vapor (saturated water vapor pressure) when it is the same as its air.
Normal observations: Thermometer readings should be accurate. When the temperature is below 0, a minus sign ("-The reading should be recorded in the corresponding column of the observation book, and the deviation correction should be carried out according to the attached verification certificate.
If the indication exceeds the range of the certificate, the correction is based on the correction value of the highest (or lowest) temperature value listed on the certificate.
Attention should be paid to thermometer readings:
1. When observing, the line of sight must be flush with the top of the red alcohol column (or mercury column) to avoid parallax.
2. The reading action should be fast, strive to be agile, do not breathe into the thermometer, try to shorten the residence time, and do not make the head, hands and lamp close to the ball to avoid affecting the temperature indication.
3. Pay attention to re-reading to avoid misreading or reversing the error of zero up and down zero.

It is more appropriate to keep the indoor temperature between 18 and 22 degrees, and the relative humidity should be set between 40% and 70%.
However, it should also be divided into different seasons, such as summer, the indoor temperature is about 25 degrees, and the relative humidity should be 50% to be more comfortable. In winter, the air is relatively dry, and the corresponding indoor temperature can reach 22 degrees, while the humidity is controlled between 60% and 70%.
Methods of humidification.
There are more and more types of humidifiers on the market, and the functions are becoming more and more user-friendly, controlling the degree of humidification, including the setting time. However, the use of humidifiers also needs to pay attention to the correct method, on the one hand, the humidifier should be cleaned regularly, and the humidity should also be within a reasonable range, not excessive, otherwise it will cause air pollution.
You can also place plants, raise some hydroponic plants, or place a pot of water in the room and place a fish tank, which can not only increase the humidity, but also increase the ornamentality.

The humidity is too low, and staying for a long time will make it tight, dry, and easy to catch fire. The most pleasant indoor temperature and humidity are: (more than 95% of people feel comfortable in this range).
Winter temperature is 20 to 25 with relative humidity.
30% to 80%.
In summer, the temperature is 23 to 30 and the relative humidity is 30 to 60 percent.
People will feel most comfortable in an air-conditioned room with a room temperature of 20 to 25 and a humidity of 40 to 50 percent.
Efficiency. High room temperature: 20, relative humidity should be 40% to 60%, at this time, people's mental state is good, thinking is the most agile.

Normal humidity ranges from 40%-80%. Generally speaking, humidity around 40%-60% is the most appropriate, if the humidity is too low, the human body will feel dry, if the humidity is too high, the human body will also feel uncomfortable, studies have shown that when the humidity is above 65%, the breeding and reproduction of germs will be significantly accelerated.
According to the requirements of the national indoor air quality standards, the indoor air humidity standard is 30%-60% in winter, and the humidity divergence index is 50%-60%.
When the humidity in the mold rolling room is too high, you can use a dryer to reduce the humidity in the room, and when the humidity in the room is too low, you can use a humidifier to increase the humidity in the room.

Humidity of 60% is a physical quantity that indicates the degree of dryness of the atmosphere.
The less water vapor is contained in a certain volume of air at a certain temperature, the drier the air, and the more water vapor there is, the more humid the air, and the degree of dryness and wetness of the air is called "humidity".
Humidity indicates the physical quantity of how dry the atmosphere is. The less water vapor is contained in a certain volume of air at a certain temperature, the drier the air; The more moisture, the more humid the air. The degree of wetness and dryness of the air is called "humidity". In this sense, absolute humidity is commonly used.
Relative humidity, comparative humidity, mixing ratio, saturation difference and other physical quantities; If the weight of water vapor in wet steam is expressed as a percentage of the total weight (volume) of steam, it is called the humidity of steam.
Dry. Relative humidity.
The upper limit value should not exceed 80 and the lower limit value should not be less than 30. Not very humid in the range, the most pleasant indoor temperature and humidity are: 18 to 25 and 30 humidity. Air humidity. >>>More

Cutting the stems to promote germination All kinds of orchids, especially black orchids (primrose), should be cut off as soon as possible after the flowers have withered, and do not let them bear fruit, so as not to consume nutrients and affect the germination of axillary buds. After the peduncle is removed, the leaf surface and back of the orchid should be gently rubbed with soft gauze or dimethoate or dichlorvos solution dipped in a cotton ball to remove eggs, dust and stains, and welcome the arrival of the new growth season. >>>More
