So, what is fatigue? It’s not a fancy word. Most of us probably think it’s synonymous with being tired. But, is it?
Wikipedia’s entry for fatigue includes:
Fatigue is a subjective feeling of tiredness that has a gradual onset. Unlike weakness, fatigue can be alleviated by periods of rest. Fatigue can have physical or mental causes. Physical fatigue is the transient inability of a muscle to maintain optimal physical performance, and is made more severe by intense physical exercise. Mental fatigue is a transient decrease in maximal cognitive performance resulting from prolonged periods of cognitive activity. It can manifest as somnolence, lethargy, or directed attention fatigue.
There were frequent times when I felt like I had a good night’s sleep but I would experience sudden fatigue during the day. It didn’t make sense until I started paying attention to when the fatigue would appear. It took awhile before I fully understood a pattern and started to have more control over the bouts of fatigue.
Aside from doing my best nightly sleep hygiene, I changed my diet to smaller, more frequent meals. My body can’t handle larger meals nor certain types of food. Once I made these dietary changes, my bouts of fatigue became less frequent.
