We study the cosmological effects of two-body dark matter decays in which the products of the decay include a massless and a massive particle. Here, we show that if the massive daughter particle is slightly warm it is possible to relieve the tension between distance ladder measurements of the present-day Hubble parameter with measurements from the cosmic microwave background.
