Excuse me, you will probably say, I thought we were talking about foods that will give me energy? Exactly. As you know, over 2/3 of our body is made up of water, we need it to keep us functioning so it is only natural that a lack of water will have a negative impact on our health and energy level.
Take a glass or two in the morning before breakfast to ensure you start the day well-hydrated. If you feel hungry inbetween meals, chances are your body is actually just thirsty, so try drinking some water before getting something to eat. Studies have also shown that even slight dehydration can impact our concentration and energy-levels, so being well-hydrated is basic when you are searching for ways to get more energized.
A good idea is having your refillable water bottle on your desk and drinking 1-2 bottles during your work day. Having the bottle close to you helps you remember to stay hydrated during office hours.
