Humans and many other mammals have unusually efficient internal temperature regulating systems that automatically maintain stable core body temperatures(核心体温)in cold winters and warm summers. In addition, people have developed cultural patterns and technologies that help them adjust to extremes of temperature and humidity(湿度).
In very cold climates, there is a constant danger of developing hypothermia(低体温), which is a life threatening drop in core body temperature to below normal levels. The normal temperature for humans is about 37.0℃. However, differences in persons and even the time of day can cause it to be as much as 6℃ higher or lower in healthy individuals. It is also normal for core body temperature to be lower in elderly people. Hypothermia begins to occur when the core body temperature drops to 34.4℃. Below 29.4℃, the body cools more rapidly because its natural temperature regulating system usually fails. The rapid decline in core body temperature is likely to result in death. However, there have been rare cases in which people have been saved after their temperatures had dropped to 13.9-15.6℃. This happened in 1999 to a Swedish woman who was trapped under an ice sheet in freezing water for 80 minutes. She was found unconscious, not breathing, and her heart had stopped beating, yet she was eventually saved despite the fact that her temperature had dropped to 13.7℃.
In extremely hot climates or as a result of uncontrollable infections, core body temperatures can rise to equally dangerous levels. This is hyperthermia. Life threatening hyperthermia typically starts in humans when their temperatures rise to 40.6-41.7℃. Only a few days at this extraordinarily high temperature level is likely to result in the worsening of internal organs and death.
Want to explore new cultures, meet new people and do something worthwhile at the same time? You can do all the three with Global Development Association (GDA).Whatever stage of life you're at, wherever you go and whatever project you do in GDA, you'll create positive changes in a poor and remote community (社区).
We work with volunteers of all ages and backgrounds. Most of our volunteers are aged 17-24. Now we need volunteer managers aged 25-75.They are extremely important in the safe and effective running of our programmes. We have such roles as project managers, mountain leaders, and communication officers.
Depending on which role you choose, you could help to increase a community's access to safe drinking water, or help to protect valuable local cultures. You might also design an adventure challenge to train young volunteers.
Not only will you help our young volunteers to develop personally, you'll also learn new skills and increase your cultural awareness. You may have chances to meet new people who'll become your lifelong friends.
This summer we have both 4-week and 7-week programmes:

GDA ensures that volunteers work with community members and local project partners where our help is needed. All our projects aim to promote the development of poor and remote communities.
There is no other chance like a GDA programme. Join us as a volunteer manager to develop your own skills while bringing benefits to the communities.
