Another thing that could be impacting your sleep is your pillow. A truly comfortable pillow that supports your head and neck can make all the difference between having a good night's sleep and not being able to sleep at all. Choosing the best pillow for you will depend on your preferred sleeping positions. If you like to sleep on your back or on your stomach, you can benefit from thinner pillows. If you are a side sleeper, a more ticker and more supportive pillow may be best for you.
