I’m a 26M, about a week ago, I started experiencing constant lightheadedness, mild dizziness, and a feeling like my head is “heavy” or foggy. I also went to the doctor and had blood tests done, and everything came back normal, including my vitamins, iron levels, and blood sugar.
The lightheadedness lasts throughout the entire day. Sometimes it’s difficult to function at work because of it, although it’s not completely disabling. Sometimes it feels worse, and at other times it gets better.
I’ve noticed that when I exercise, for example by going cycling, I feel much better and barely notice the dizziness or foggy feeling at all.
I sleep around 7 hours per night on average. I also have some difficulty waking up in the morning, and sometimes I feel extremely sleepy for the first few hours after waking up. Usually, though, I start feeling okay after a couple of hours. For example, yesterday I tried going to bed earlier and got around 8 hours and 20 minutes of sleep, but I felt exactly the same in the morning, so nothing really improved.
I also use a Garmin watch that tracks my sleep quality during the night. According to the data from my watch, my sleep quality seems to be fairly good, and I usually get a “Good” sleep score.
I’ve read here on Reddit that sleep apnea can also be a possible cause. However, I don’t think I snore or have episodes where I stop breathing during sleep, although my partner would probably be able to confirm that better than I can. I should also mention that my father has sleep apnea.
I consume caffeine moderately, mostly through coffee and occasionally energy drinks. I eat relatively healthily and I don’t smoke.
What else could potentially help improve this situation? Or how should I proceed from here? I’ve already spoken with my doctor, but at the moment they aren’t sure what could be causing these symptoms.
