“…This evidences the possible influence of sea proximity, which appears to relieve uncomfortable conditions. This result confirms the outcomes of Cannistraro et al 49 , which revealed better comfort conditions in coastal cities subject to constant ventilation than in inner areas, using different approach and index and comparing the data of various stations.…”

Several studies evidenced the importance of the knowledge of the bioclimatic comfort for improving people's quality of life. temperature and relative humidity are the main variables related to climatic comfort/discomfort, influencing the environmental stress in the human body. In this study, a stochastic approach is proposed for characterizing the bioclimatic conditions through the Humidex values in six sites of calabria (southern italy), a region often hit by heat waves in summer months. the stochastic approach is essential, because the available time series of temperature and relative humidity are not long enough and present several missing values. the model allowed the characterization of sequences of extreme values of the Humidex. Results showed different behaviours between inner and coastal stations. For example, a sequence of 20 consecutive days with maximum daily Humidex values greater than 35 has a return period ranging from 10 to 20 years for the inner stations, while it exceeds 100 years for the coastal ones. The maximum yearly Humidex values for the inner stations have a larger range (40-50) than the coastal ones (38-45), reaching higher occurrence probabilities of serious danger conditions. Besides, the different influence of temperature and relative humidity on the Humidex behaviour has been evidenced. Bioclimatic comfort is a cognitive process that mixes many stimuli influenced by physical, physiological, and psychological factors 1. Previous researches evidenced the fundamental importance of the knowledge of the bioclimatic comfort for improving people's quality of life. In fact, in the last years temperatures over 36 °C, especially in situations of heat waves, severely affected people's health, mainly if children, elderly and chronically ill 2,3. An increase of severe heat waves in the current century has been forecasted in areas already affected by heat stress, such as the southern part of the European continent 4-6 and the Mediterranean basin, which is expected to face particularly high impacts from global warming and climate change and to be most vulnerable to their deleterious effects 7. The effects of heat can be various: increase of mortality 8 , working/exercise capacity 9,10 and cognitive performance 11,12. For the analysis of bioclimatic comfort, in studies conducted at different spatial scales in various parts of the world (e.g. in America 13-16 , in Europe 17-19 , in Asia 20-22 and in Oceania 23) several parameters such as temperature, relative humidity of the air, wind and radiation have been analysed. In particular, given their influence on the environmental stress in the human body, temperature and the relative humidity of the air are the key basic parameters related to climatic comfort/discomfort 1. In fact, as stated by Masterton and Richardson 24 , with different humidity conditions the same temperature can provide very different feelings to people. For this reason, in order to detect the effect of heat on human health, an index that combines the effects of temperature and humidit...

“…These indices could be calculated through empirical formulas, depending on specific environmental parameters such as temperature, relative humidity, solar radiation and wind speed. Cannistraro et al [30] produced a thorough description of some of the main indices (e.g., Scharlau Index, Heat Index, New Summer Simmer Index, Equivalent Temperature, Thom index and Wind Chill) evidencing for each index the parameters considered and the field of application. For example, the Summer Simmer Index considers temperature and relative humidity and can be applied for temperature ranging between 22 • C and 53 • C. Temperature, relative humidity, solar radiation and wind speed are required to determine the Equivalent Temperature where the parameters depend on the geographical location.…”

“…The humidity index (Humidex) is one of the most popular indices, and consists of a simple thermal comfort index using air temperature and humidity [28]. This index can be applied for temperature values ranging between 20 • C and 55 • C [30]. Its results directly compare with dry temperature in degrees Celsius and its values have corresponding degrees of thermal comfort.…”

Knowledge of bioclimatic comfort is paramount for improving people’s quality of life. To this purpose, several studies related to climatic comfort/discomfort have been recently published. These studies mainly focus on the analysis of temperature and relative humidity, i.e., the main variables influencing the environmental stress in the human body. In this context, the present work aims to analyze the number of visits to the hospital emergency department made by the inhabitants of the Crati River valley (Calabria region, southern Italy) during the heat waves that accompanied the African anticyclone in the summer of 2017. The analysis of the bioclimatic comfort was performed using the humidity index. Results showed that greater the index, the higher the number of accesses to the emergency department, in particular by the most vulnerable population groups, such as children and the elderly.
