I feel tired since i have been busy for work for many days. is there a way that i can work ultimately without being tired? seeking for advice.

Expending energy: When you work, you expend energy and then feel tired. Daily exercise and eating well, staying well hydrated can all combat excessive energy loss, and may ultimately help you feel less tired when working. Some times, we need to work harder than the amount of exercise we can do to stay fit, and you just get tired from a "long days work." Stay well, God Bless, Best wishes.
