In this seminar I will review how current cosmological probes can help us to constrain the properties of neutrinos. I will briefly describe how neutrinos decouple in the early universe and what is the state-of-the-art prediction on their energy density and the constraints we obtain from cosmological measurements in the standard scenario. Then, I will show how the constraints change when considering non-standard cases, such as non-standard interactions, neutrino decay, or different properties of the cosmological model under consideration.
