We have all had the ‘blah’ feelings when suffering a cold. A new study indicates why we feel not only sick but also depressed when we have a cold. What the researchers found is that the transporter for serotonin (depression and low serotonin have long been linked together) activity is increased, so there is less serotonin at the synapse to do its job. This reduced level of serotonin at the synapse could explain the depressive mood when infected with a cold.
So try to keep healthy to prevent the catching of a cold (yes, easier said than done). To better brain health now, and the coming new year.
