Relaxation rates provide important characteristics both for classical and quantum processes. Essentially they control how fast the system thermalizes, equilibrates, decohere, and/or dissipate. Moreover, very often they are directly accessible to be measured in the laboratory and hence they define key physical characteristics of the system. In my talk I show that relaxation rates for any Markovian evolution of an open system satisfy a universal tight constraint (valid for all quantum systems with finite number of energy levels). Some implications of this result are discussed as well.
