Hot and humid days may not exactly be your favorite type of weather. This article may help you understand why they feel sticky and sometimes the temperature may feel hotter than the thermometer really says.
For many people, humidity is simply the amount of microscopic water particles floating in the air. The earth’s surface at this moment, is around 70 percent covered with water. A very minimal amount of this water becomes vapor. However, the amount of it is important for predicting the weather.
For those of you who know how evaporation works, it is simple to understand how humidity came to exist. Humidity simply occurs when a certain amount of heat comes from the sun or other sources, and that thermal energy transforms into kinetic energy; causing the water to rise above the surface and hover in the air. As thermal energy increases, humidity also increases at a significant rate.
When water evaporates it needs to go upwards, and it usually goes up into what is known as the stratosphere and forms clouds. When the cloud becomes saturated properly, it will precipitate. In other words, water will fall to the ground from the sky. It all depends on the temperature of the water.
When you read a hygrometer, the reality is that you are reading relative humidity. Weather forecasts usually include relative humidity in their reports. It is the amount of water vapor at a given time in the air compared to how much is required for precipitation (rain) at a temperature. The relative humidity displayed in a hygrometer is given in a percentage and can help predict the weather greatly. You know that rain is coming when the relative humidity reads 100 percent.
Humid conditions often make humans uncomfortable to some degree. For example, you might feel a little warm and sticky. Your body keeps its temperature stable by means of sweating, and in high humidity, it cannot properly become vapor. This causes uncomfortable feelings on a day with high humidity. Your sweat normally evaporates somewhat on a hot day, but if there is too much humidity, the sweat will not dissipate properly. Instead, the sweat will be re-moistened by the surrounding humidity. When your surroundings are too warm for you to release heat, you might even feel lazy. Environmental conditions have proven to be psychologically effective on people under many different circumstances.
So what is the proper amount of humidity for a person? People usually feel comfortable in the range of 30 percent to 60 percent humidity. Temperate climates, in places such as those above the Tropic of Capricorn or below the Tropic of Cancer, are the most appropriate for most people. Otherwise, people might be in need of humidifiers, or dehumidifiers.
Such a thing as humidity is exactly what drives us to behave in certain manners and feel in a certain manner also. We are all affected by our environmental conditions and can adapt to them. Some people feel more comfortable with higher humidity, and some of us can say the same about living in lower humidity than usual.
