Identify a valid reason some people experience nose bleeding at high elevations. A higher red-blood-cell count (relatively) is required to maintain physical activity in lower oxygen levels. O Individuals who live at high elevations are statistically more likely to insert a finger into a nostril. Relatively low pressure outside thin-walled veins. Relative humidity is lower at high elevation.

ASHRAE standard 55, Thermal Environmental Conditions for Human Occupancy, notes that for thermal comfort purposes, the indoor temperature should range from approximately 67ºF to 82°F (19.4ºC to 27.8ºC), and systems designed to control humidity must be able to maintain a dew-point temperature of 16.8°C (62.2°F). ASHRAE standard 62.1, Ventilation and Acceptable Indoor Air Quality, recommends that relative humidity in occupied spaces be controlled to less than 65% to reduce the likelihood of conditions that can lead to microbial growth. Determine the minimum allowable indoor temperature that will ensure a humidity control system designed according to ASHRAE standard 55 will also satisfy the humidity requirements of standard 62.1
