This page shows two of the most interesting tables (Humidex Index and Thom's Index) useful to evaluate how current temperature and relative humidity can affect the sultriness or discomfort sensation and cause health danger in the population. ... Thom's Index: Up to 21[°C:] No discomfort. From 21 to 24. Less than half population feels discomfort. From 25 to 27. More than half population feels discomfort. From 28 to 29. Most population feels discomfort and deterioration of psychophysical conditions. From 30 to 32. The whole population feels an heavy discomfort. Over 32. Sanitary emergency due to the the very strong discomfort which may cause heatstrokes.  7, record 1, English, - temperature%2Dhumidity%20index

Effets de la température et de l'humidité sur le corps humain exprimés par la formule: DI = 0.4 (Td + Tw) + 15 où Td = température du thermomètre sec (en degrés F); Tw = température du thermomètre mouillé (en degrés F).

Indice température-humidité. D'origine américaine, l'indice température-humidité est similaire à l'humidex canadien. C'est l'équivalent estival du facteur éolien en hiver. De même que le vent accentue la perception (et l'impact physiologique) du froid, l'humidité accentue la perception et l'impact de la chaleur. Chacun sait qu'un temps chaud et humide est beaucoup plus pénible qu'un temps chaud et sec!  4, record 1, French, - indice%20temp%C3%A9rature%2Dhumidit%C3%A9

Un índice conocido y usado [...] para guiar el desconfort o el confort, basado en las condiciones de temperatura y humedad, es el índice de temperatura- humedad (ITH). A fin de calcular el ITH [...] se usa la siguiente fórmula: ITH = T - 0.55 (1-HR) (T-14) donde T es la temperatura del aire (en grados centígrados) y H es la humedad relativa expresada en fracciones decimales. [...] un ITH entre 15 y 20 es aceptable por la mayoría [de las personas] como confortable.  1, record 1, Spanish, - %C3%ADndice%20de%20temperatura%2Dhumedad

The comfort index provides an indication of the body's reaction to heat, cold, humidity and wind chill. High temperatures and humidity stress the body's ability to cool itself, and low temperatures can stress the body's ability to heat itself. It is not an absolute measure as everybody's reaction to heat and cold is different.  3, record 2, English, - comfort%20index
