Circadian Rhythm

The Circadian Rhythm

It's the time of year where summertime begins and we reset our body clock. In the UK we move our clocks forward an hour which signifies longer days of sunlight and also coincides with the revision and exam period. The circadian rhythm is responsible for sleep patterns, body temperature, blood pressure and mood.

Find out about your circadian rhythm, how it can effect you, where it is, and where it originates from.
