ABSTRACT
Indoor working exposure to cold offer constant and predictable climate conditions, which facilitates cold risk management and workers cold adaptation. The different types of cold adaptations are related to the intensity of the cold stress and to individual factors such as body fat content, level of physical fitness and diet. The hypothermic general cold adaptation seems the most beneficial for surviving in the cold but the interest of the development of general cold adaptation in workers in the cold are questionable since occupational activities can be organized to avoid cold disturbances (shelter, clothes, heat sources, time sharing). For the workers working in cold environments, adaptations of extremities are beneficial, as are developing cold induced vasodilation, improving manual dexterity and pain limits
1 INTRODUCTION
The frozen food deliver high quality, good value, safe foods with an extended storage life, helping the dietary portion control and reducing waste, offer the possibility to preserve and use seasonal foods all year round (Young et al. 2010). In emerging markets like Latin America, South East Asia and Eastern Europe, an increase demand for richer and more varied diets will occur and, importantly, increase demand for large domestic appliances such as freezers (Kennedy 2000). Further on, shifts in global economic, social and demographic trends will continue to put pressure on food supplies, as we already witness today, more frozen foods to be sold each year and new products introduced to swell the total sales (Artley, Reid, and Neel 2008). The structure of the labour market is constantly undergoing change, away from fresh and homegrown towards
(Launay and Savourey 2009). Workers with less years of activity seem to be more satisfied with the cold thermal ambient than veterans with more than 10 years (Oliveira et al. 2014). Cold work involves several adverse health effects that are observed in indoor work. Many of these adverse outcomes may be further aggravated in persons having a chronic disease (Mäkinen and Hassi 2009).
