Feeling tired among adults is quite common. Our lifestyle these days is such that we don’t get enough rest and even when we are not working, there is so much to distract us (for example streaming services and social media) that we don’t get enough rest. When you are depriving yourself of sleep for entertainment, it doesn’t mean you are resting. Hence, if you feel fine after taking a good night sleep or after taking some healthy food, it means the fatigue is normal. If the fatigue does not go away, maybe you need a fatigue test after consulting your doctor.
