Heat Strain in Cold

Heat strain in cold.

In spite of increased environmental cold stress, heat strain is possible also in a cold environment. The body heat balance depends on three factors: environmental thermal conditions, metabolic heat production and thermal insulation of clothing and other protective garments. As physical exercise may increase metabolic heat production from rest values by ten times or even more, the required therm...

Cold drink attenuates heat strain during work-rest cycles.

There is limited information on the ingestion of cold drinks after exercise. We investigated the thermoregulatory effects of ingesting drinks at 4°C (COLD) or 28°C (WARM) during work-rest cycles in the heat. On 2 separate occasions, 8 healthy males walked on the treadmill for 2 cycles (45 min work; 15 min rest) at 5.5 km/h with 7.5% gradient. Two aliquots of 400 mL of plain water at either 4°C ...

Ice Slurry and Cold Drink Reduces Exercise Induced Physiological Strain in the Heat

Investigation of stress and heat strain in asphalt workers

Heat stress is one of the harmful factors in workplaces. Asphalt workers are exposed to thermal stress due to the open environment and process. The aim of this study was to assess the heat stress and strain in asphalt workers. This study was conducted on 29 employees of asphalt workstation. The heat stress was measured based on Wet-Bulb Globe Temperature (WBGT). Also, physiological parameters s...

Evaluating physiological strain during cold exposure using a new cold strain index.

A cold strain index (CSI) based on core (Tcore) and mean skin temperatures (T sk) and capable of indicating cold strain in real time and analyzing existing databases has been developed. This index rates cold strain on a universal scale of 0-10 and is as follows: CSI = 6.67(Tcoret - Tcore 0) ⋅ (35 - Tcore 0)-1 + 3.33(T sk t -T sk 0) ⋅ (20 -T sk 0)-1, where Tcore 0 andT sk 0are initial measuremen...
