It would feel pretty hot, because 40°C=104°F, which is hot.

Unbearably hot.

Humidity is a measure of how saturated the air is with water; 100% humidity means that no more water can be suspended in the air. The human body cools itself by sweating. This involves the evaporation of sweat from the skin, which absorbs energy in the form of heat, drawing it away from the body and cooling it. If there is less water already in the air - i.e. a low humidity - it will be easier for sweat to evaporate; higher humidity means it is harder, and 100% means it is impossible. Thus, a higher humidity means it will feel hotter because your body cannot cool itself down as well as normal.
Air at a higher temperature can hold more moisture, so the warmer air at 30 degrees Celsius will evaporate less sweat from your skin compared to the cooler air at 10 degrees Celsius. This reduced evaporative cooling can make you feel stickier in the warmer air even though the relative humidity is the same.

The relationship between temperature and relative humidity impacts comfort level in an environment. High humidity can make it feel hotter than it actually is, while low humidity can make it feel cooler. When the temperature and humidity are balanced, it can create a more comfortable environment.
The relative humidity is typically higher in the early morning and evening due to cooler temperatures causing saturation levels to rise, leading to higher humidity. In contrast, relative humidity is usually lower during the afternoon when temperatures are higher and the air can hold more moisture, making the air feel drier.
Relative humidity is a measure of the amount of moisture in the air compared to the maximum amount it can hold at a specific temperature. It is expressed as a percentage, with 100% representing saturated air. Relative humidity affects how comfortable we feel in a given environment and can influence the likelihood of condensation or mold growth.
High relative humidity in the summer can make the air feel more sticky and oppressive. This can result in a feeling of discomfort because the body's ability to sweat and cool down is reduced when the air is already saturated with moisture.
Relative Humidity is measured with a HygrometerHumidity is the amount of water vapor in the air.On hot days, when it feels sticky, the humidity would then be high.
Relative humidity does not measure how hot it feels, but rather it measures the amount of water vapor present in the air compared to the maximum amount the air can hold at a particular temperature. High relative humidity can make it feel hotter because it affects the body's ability to cool itself through sweating.
Humidity plays an important role in human comfort. People feel cooler in drier air because their perspiration can readily evaporate. They feel warmer in air with a higher relative humidity because the evaporation process is slower. The surrounding air has to be able to absorb water or sweat so that evaporation occurs. Evaporation requires that the body produce sweat and that the air is able to absorb it. Relative humidity in excess will make a human feel discomfort because the air will not be able to absorb the perspiration from their body which removes heat.
The heat index, or "feels like" temperature, is 97 degrees Fahrenheit when the air temperature is 88 degrees Fahrenheit and the relative humidity is 74%. This indicates how hot it actually feels to the body when both temperature and humidity are taken into account.
A relative humidity of 75 percent means that the air is holding 75 percent of the maximum amount of moisture it can contain at a given temperature. This indicates that the air is quite humid, which can make it feel warmer and more uncomfortable. When relative humidity reaches this level, condensation may occur, leading to the potential for dew or fog. High relative humidity can also affect drying processes and increase the risk of mold growth.
The "RH" on a thermostat stands for relative humidity, which measures the amount of moisture in the air. This affects temperature control in a room because higher humidity levels can make a room feel warmer, even if the temperature setting on the thermostat is the same. Conversely, lower humidity levels can make a room feel cooler. Monitoring and adjusting the relative humidity on a thermostat can help maintain a comfortable and consistent temperature in a room.
