Humanitarian aid is material and logistic assistance, usually in the short-term, to people in need. Among the people in need are the homeless, refugees, and victims of natural disasters, wars, and famines. The primary objective of humanitarian aid is to save lives, alleviate suffering, and maintain human dignity.

Suffering, agony, or pain in a broad sense, may be an experience of unpleasantness or aversion, possibly associated with the perception of harm or threat of harm in an individual. Suffering is the basic element that makes up the negative valence of affective phenomena. The opposite of suffering is pleasure or happiness.
