Why am I always tired no matter how much I sleep?

I’m 17, and no matter how much I sleep, I’m always tired. I don’t understand why this keeps happening. Any ideas?

It might be your thyroid, vitamin deficiencies, depression, or even a sleep disorder. I’m always tired too, so I understand how frustrating it is. Try to get some lab work done; it could help you figure out what’s going on!

Thanks for the advice! I don’t think it’s physical since my blood tests didn’t show any deficiencies, and I take magnesium at night. But does mental health really affect sleep this much?

It definitely can! Mental health conditions like depression or anxiety can cause constant stress and fatigue. Did your blood test check your thyroid, or was it just for vitamins? Thyroid issues, like hypothyroidism, can also cause extreme tiredness.

@Shannon
The test was only for vitamin deficiencies, and my mental health hasn’t been great for a while now. So maybe it’s a combination of both?

It could be a mix of things—hypersomnia, oversleeping fatigue, thyroid issues, or even lifestyle factors. If you can, try seeing a doctor to narrow it down. Good luck! I’m 16 and also deal with crazy fatigue, so I totally get it.

@Shannon
Thank you so much, and good luck to you too. I’ll try to make an appointment with my doctor soon.

What kind of blood tests did you have done?

@Ashton
Just a basic blood test to check for vitamin deficiencies and stuff like that.

There’s a 99% chance it’s related to your diet or hydration. Do you eat a lot of processed foods like chips, white bread, or soda? If so, that might be a good place to start improving.

Actually, I eat pretty healthy, so I don’t think it’s my diet. I also take magnesium pills before bed.

@Alby
Did they check your iron and vitamin D levels? Those are often missed but can cause tiredness if low.

I recently had a blood test, and everything was fine. Plus, I take vitamin D3 + K2 every morning.

It could be a lot of things—diet, lack of exercise, screen time, or even mild sleep apnea that you might not know about. If this keeps up, you might want to look into getting a sleep study done to rule out underlying sleep issues.
