Why do I wake up every hour, on the hour?

Maybe you are regretting something from the past or something is stopping you from something you must do

Could be many things. Restless leg syndrome? Overactive bladder? You aren't tired? You need ear plugs or an eye shade? 7 Cups has a really great unit on sleep. I have struggled with sleep most of my life. And for me its finding a great rhythm and sticking to it. Even when its extreme. I used to be on a 12am bed time. Wake at 230, then go back to sleep and wake at 5am. i stuck to that for 4 years and was rested enough. Now a days I'm in different beds often and sometimes sleeping by 9pm and waking at 520am. so I keep waking up at odd moments. For me its also connected to if I had coffee, if i drank too much water before bed, if I payed video games before bed etc etc. But I would encourage you to look through the sleep unit on 7 cups or google it a little bit find your rhythm. You also might be snoring and waking yourself up :D I have done that too.

Sometimes, this could be caused by menstrual cramps. Have you had these lately? This is a common cause.

You might be having insomnia, the kind that makes it hard for you to stay asleep. Maybe you could see a sleep doctor to determine the cause.

This could be for many different reasons. Emotionally, there could be some reason for you waking up. There also could be some medical reasons behind it as well. The best thing to do is think about if you're experiencing any heavy thoughts before bed, whether the sleep environment you're in is comfortable, or if there is a medical cause, get to the bottom of it by speaking with a doctor. Also, if at all possible, ask someone who has been around you while you're sleeping if they've noticed anything.

You might be stressed, there is maybe something that is haunting you, in which case the best thing you can do is to monitor your thoughts to see what you are struggling with.

It might be anxiety. I would suggest talking to your doctor about your current health concerns. They would be best able to provide an expert opinion.

Are you under stress in your life? Are you having nightmares? or perhaps are you going to bed too early? These are some reasons why you are waking up several times a night.

It sounds like a sleeping disorder to me. It's not good for your mental health to not get enough sleep. I recommend speaking to your doctor.

How have you been feeling lately? Any anxiety or depression? Something in your life making you worry?
