The reasons why you may feel tired and depleted of energy can vary from simple, such as lack of sleep or dealing with stress at work, to much more complex ones.

One of our main sources of energy is, of course, the food we eat. So, if we want to keep our energy levels up, we must eat healthfully and try to integrate the most nutritious foods in our diets. We measure the energy that we can derive from foods in calories .

If we don't consume enough calories our bodies may feel tired, as they don't have enough "fuel" to run on. At the same time, however, if we get too many calories, there's a system overload, and we may end up feeling sluggish.

So, in order to feel fresh and ready for action, we must learn to maintain a balance in terms of our calorie intake.

At those times, I find it useful to get up from my chair, stretch a little, walk around the office, and then continue work at the standing desk.

Practicing yoga and meditation might also help to boost your energy levels. This is because these practices focus on techniques — such as mindful breathing — that aim to promote a state of calm.
