It is important to remember that beyond just the high air temperature, wind, humidity and sun can also play a role. These other factors affect how hot it feels to a person, which can vary quite a bit from the air temperature. Known as the Heat Index, how hot it feels isn't just a matter of mental comfort, it also affects the body's response to the heat.<\/p>\n<p>A strong dry wind&nbsp;can remove moisture from the skin very quickly,&nbsp;fooling a person into thinking that it is not so hot because there is no sweat.<\/p>\n<p>Conversely, high humidity with relatively less heat can also be dangerous without&nbsp;the cooling effect of&nbsp;evaporating sweat.<\/p>\n<p>Finally, direct exposure to sunlight can increase the heat effect by up to 8\u00baC above the air temperature.<\/p>\n<p>The chart below&nbsp;shows the Heat Index, a&nbsp;way to indicate&nbsp;how the combination of air temperature and humidity can lead to a&nbsp;perceived temperature. For example, if the air temperature is 40\u00baC and the relative humidity is 25%, it can feel to a person as if it is 41.1\u00baC, which is not very different. However, if the humidity is 35% then it will feel as if the surrounding temperature is 45.6\u00baC. As another example, if the air temperature is 45\u00baC and the humidity is 25%, it can feel to a person as if it is 50.6\u00baC.<\/p>\n<p>&nbsp;<\/p>\n<p><a href=\"http:\/\/newspie.in\/en\/wp-content\/uploads\/sites\/3\/2016\/05\/heatindex_c.jpg\" rel=\"attachment wp-att-3970\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-thumbnail wp-image-3970\" src=\"http:\/\/newspie.in\/en\/wp-content\/uploads\/sites\/3\/2016\/05\/heatindex_c-270x250.jpg\" alt=\"Beyond temperature, the Heat Index tells you how hot it feels\" width=\"270\" height=\"250\"><\/a><\/p>\n<p>To find the Heat Index, along the left side locate the closest temperature value&nbsp;to the outside temperature, then find the relative humidity that is closes to the actual condition along the top.
