With wildfire smoke from fires throughout the Northwest continuing to linger in the Gorge, health officials continue to remind people about potential issues that come from that, especially for the elderly and very young.  Ellen Larsen of the Hood River County Health Department says the particles in this kind of smoke are very fine, and are easily breathed into the lungs, so strenuous exercise is discouraged.  She adds staying hydrated is important.  Larsen also pointed out the need to drink plenty of water during the hot temperatures that have been in the area over the past couple of weeks.
