It's weird how sometimes, despite having had a solid eight hours of sleep the night before, you can find it almost impossible to get out of bed. How can this be? It doesn't make sense. Sure, your bed is nice and warm and cozy, but it shouldn't be this hard to force yourself to get up!
However, it seems there might be a real, scientific reason behind the problem: atypical depression. While it certainly won't be the case with everyone—the signs and symptoms of atypical depression are different to the classic indications of the mental health disorder—it could be the reason you're unable to get out of bed each day.
Health looked into it and spoke to their contributing psychology editor, Gail Saltz, for answers. Saltz explained what atypical depression is: a sub-type of the common mental health disorder which means that sufferers don't always feel down. People who have atypical depression might not even be aware of it, because their mood can lift with positive circumstances.
Describing the symptoms, Saltz said: "Instead of trouble sleeping and loss of appetite, you sleep too much and eat too much."
It's worth noting that these kinds of symptoms should be noticeable for at least two weeks in potential cases of atypical depression. If you're concerned it might be something that's affecting you, it's definitely necessary to go see a medical professional, because atypical depression can be treated in exactly the same way as depression—with the aid of either therapy or medication.
But don't immediately jump to conclusions that atypical depression is what's causing your unexplained tiredness, either. As the NHS points out, there are several possible causes, including anemia, celiac disease, chronic fatigue syndrome, diabetes, thyroid issues, and more.
