3.D 该段最后一句说 The regular use of a sauna may decrease the likelihood of getting a cold;第四句说 they may help to … speed recovery time;第一句说 Saunas are … stress relieving.所以，A、B、C都是桑拿可以做的。第三句Asthma patients find that the heat enlarges air passageways of the lung and facilitates breathing，这不足以说明桑拿有治愈小船的作用。因此，应选择D.
4.A 该段第三局提供了答案。
