暖暴胀是一种暴胀现象，其中在暴胀过程中，热浴与暴胀子共存。这与标准的冷膨胀不同，在标准的冷膨胀中，宇宙在膨胀过程中实际上没有粒子。暖暴胀中的热浴是通过暴胀子与其他场的耦合耗散暴胀子的能量来维持的。人们已经提出了许多关于暖膨胀的模型，并将它们的预测与宇宙学数据进行了比较。某些在冷通货膨胀背景下被数据所禁止的通货膨胀模型在暖通货膨胀情景中是允许的，反之亦然。
Warm inflation is an inflationary scenario in which a thermal bath coexists with the inflaton during inflation. This is unlike standard cold inflation in which the Universe is effectively devoid of particles during inflation. The thermal bath in warm inflation is maintained by the dissipation of the inflaton's energy through its couplings to other fields. Many models of warm inflation have been proposed and their predictions have been compared with cosmological data. Certain models of inflation that are disallowed in the context of cold inflation by the data are allowed in the warm inflationary scenario, and vice versa.
