SAN DIEGO , California ( CNN ) -- Many among the thousands of evacuees from California 's wildfires were suffering from stress and worry about their homes after seeking shelter at San Diego 's Qualcomm Stadium , said a pair of Navy medical volunteers Wednesday . Navy medics Daniel Brautigam , left , and Jacob Hackfeld volunteered to help wildfire evacuees . The stadium -- home to the NFL 's Chargers -- at one time housed 11,000 evacuees , but that number dropped to 7,500 this morning . Of the thousands of people who 've been sleeping , eating and passing time at the arena , many are showing symptoms of stress , said Petty Officer Daniel Brautigam . Patients are showing `` a lot of smoke-induced nausea , '' he said . `` A lot of people are watching TV while they 're here -- they 're watching their houses burn . '' Brautigam said the word `` panic '' came to mind to describe how some evacuees were feeling . `` But it 's not . People are just worried sick . That phrase alone explains it all . '' Watch sailors tell more about treating evacuees » . According to the San Diego 's mayor 's office , medical staff treated between 70 to 100 people since the stadium opened to evacuees . He said counselors are being made available to the evacuees at Qualcomm , where volunteers have also been providing food , tents and cots to families and others fleeing the fires . `` We 've been working nonstop now for about 48 hours with a few hours of sleep in between -- just enough to get well-rested , '' said Brautigam . Brautigam and another sailor , Seaman Jacob Hackfeld , stepped forward on their own to offer medical services after their nearby base was evacuated . Hackfeld said he was `` sitting on my couch watching TV and I 'm thinking to myself , why ca n't we come out here ? The community provides for us -- the military . Why ca n't we give back to them all the things that they 've given to us ? '' Although both men said they helped in the aftermath of 2005 's Hurricane Katrina , they said the emergency response to both disasters was markedly different . `` Here you have complete organization , '' Brautigam said . `` You have a community coming together getting things done , helping people out -- cooperation between civilians , military , everybody . See dramatic photos of the disaster » . `` Here everybody comes together , and we 're all just people . I think that 's the most important thing that 's going on right here right now . The main focus is just getting people the help that they need . '' About 300 convalescent patients who had been evacuated to Qualcomm from nearby facilities were expected to be returned later Wednesday , said George Biagi , spokesman for the San Diego mayor . More than 20 fires have scorched 400,000-plus acres from the Mexican border to northern Los Angeles County and inland into the San Bernardino Mountains since the weekend . Statewide , an estimated 950,000 people have sought refuge from the fires in shelters , hotels and at friends ' homes . The National Weather Service said a red-flag warning for extreme gusty winds was in effect through 3 p.m. PT ( 6 p.m . ET ) Wednesday , but forecasters said firefighters should see an end to the Santa Ana winds that have fueled the fires by Thursday . Some residents wo n't have to wait for Thursday to get home . People who evacuated earlier this week from Rancho Bernardo , Scripps Ranch and Del Mar Heights can go home immediately , San Diego emergency spokeswoman Lynda Pfieffer said Wednesday morning . The blazes have killed one person and injured at least 70 more . Thirty-four firefighters have been hurt , authorities said . E-mail to a friend .
