The head should be kept wet, and an ice pack applied to the neck and lower portion of the head. This will help protect the brain and central nervous system from the effects of extreme heat exposure. It will be noted that a tremendous volume of heat will be radiated by the diver. Keep cooling until the diver feels peaceful and comfortable in the cold water and is breathing deeply and easily. sighing deeply, and generally emphasizing the expulsion of air rather than struggling to get air in or holding the breath. As with febrile illness, avoid exertion, flying, trips to higher altitudes, hot tubs, saunas, electric blankets, sun bathing, tanning or other forms of manmade or natural heat and radiation.
Air conditioning presents a problem.
While some moderation of air temperature to a temperate range can enable people to work and function more comfortably, the methods of air conditioning may cause greater thermogenesis to take place. Thermostats should be set for no more than 7 to 10 degrees Farenheit below the air temperature. Greater cooling results in thermogenesis in most individuals. Baths and showers should continue to be tepid to cool for a week or more. As with any extreme of fever, the patient will not find this a comfortable regime at first.
