Why do we sleep at night

Dormir mejor por la noche que durante el día no es casualidad. La respuesta la tiene la melatonina, una hormona que segrega nuestro cuerpo de forma natural.

We sleep because our body need rest after a load of work done in the day and our brain needs to stop proccesing information for a while. We sleep at night because when there is lack of light our body immediately releases a substance called melatonin which kind of triggers the body to sleep.
