Millions of people suffer from lower back pain as a result of factors such as work, exercise, excessive prolonged positioning, or chronic conditions. Your lower vertebrae, or lumbar region, is prone to pain and muscle exhaustion. One aspect of taking care of your spine is learning how to sleep properly. Some of these positions may take time for your body to get used to; however, changing your positioning and supporting your back will pay off in the long term. If you suffer from back pain, invest in a good mattress and pillows, learn a supportive sleeping posture and take some steps to ensure a good sleep every night. Sleep can help to relax muscles and reset pain receptors, so that you wake up in the morning feeling pain-free.
