Why do I wake up feeling very sore and achey?

This could because of the position in which you lay throughout the night which could be causing the sore sensation also the amount of pillows used( e.g: too much ) can effect the neck & shoulder muscles aswell.

Well, how are sleeping at night? Does the position you wake up in seem uncomfortable. If so you could try to find a better sleeping position or trying to relax the nght before you go to sleep.

There may be a variety of reasons for this; maybe it's the position you're sleeping in, a draft of cold air from a window, anxiety or a medical issue. Take a look at some of those things just mentioned; maybe try sleeping in a different way, double check there isn't a draft before going to bed, do a mindfulness exercise and/or have a relaxing cup of warm milk (I like mine with some honey) before bed. If you think it might be a medical problem talk to your doctor.

It happens because you haven't done your supper properly or have a bad routine of waking up late. I just say I am not a medical student. But I also faced that. Try never to sleep with an empty belly. You know most of our problems start with our stomach. This small pocket of food contains a lot of sensations and even some time controls our emotions. Try to go early to bed at night and wake up early with a healthy belly. Because you know early to bed and early to rise makes a man healthy wealthy and wise. Take care.

How does your sleep schedule look? There are several different reasons that you may be sore when you wake up. The main reason is most likely your sleeping position. I used to always sleep on top of two pillows, and that made my back sore every single night. You can experiment and try what feels best for you. 2 is an unhealthy sleeping schedule. If you don't get enough sleep in a night, then you will undoubtedly wake up feeling weary or sore. You may be involved in sports or other physically rigorous activities. If this is the case, it's important to go to sleep earlier so your body can recover from injuries or sore muscles.
