Yes I’m going to let you in on the little not so secret secret. Drum roll please – it is water! Yes H2O. Scientists believe that we should be drinking at least 40 millilitres of water a day, for every kilogram that we weigh. As the brain is made up up of 85% water even a 2% decrease can effect how we function, our reaction time and fatigue.
Other drinks such as coffee and soft drinks can actually dehydrate the body so you also need to drink more water to compansate for this.
Try and keep your working body in tip top shake. Fill a bottle or put a jug next to your desk, you will be amazed by how much better you feel at the end of each day!
