The Body Clock and Alcohol

This week, we are acknowledging and paying homage to the fact that some of us will get an extra hour in bed this week. This happens because a chemical corded denosene builds up in the brain when we're awake and it gets flushed out when we nod off. But sleep is not an on-off process - our brains cycle every 90 minutes or so through phases of lighter and deeper sleep. Although booze can send use to sleep paradoxically, it also robs you of restful sleep,. contributing to feeling rough next day.
