Indeed, measurements of heat stress figure prominently in your daily weather report. At about 30.3 million km 2 (11.7 million square miles) including adjacent islands, it covers 20% of Earth's land area and 6% of its total surface area. But humid air has less capacity to hold additional moisture, so water evaporates more slowly in humid conditions. Heat exhaustion - Weakness, lassitude, dizziness, visual disturbance, feeling of intense thirst and heat, nausea, palpitations, tingling and numbness of extremities after exposure to a hot environment. Both wet-bulb temperature and heat index are calculated using data on air temperature and humidity -- the two most important factors that affect heat stress. As water evaporated from the cloth, the thermometer recorded the drop in temperature. Blood rushes to your skin to try to release heat, starving your internal organs. Manual work creates additional metabolic heat and adds to the body heat burden.
