Why is lower back pain worse when sleeping?

Answered by Michael Wilson

Lower back pain can often be exacerbated when sleeping due to the position in which we sleep and the impact it has on the spine. When lying flat on your back on a soft mattress, your lumbar spine may naturally bend forward or flex, resembling the position of looking down. This flexion can compress the discs in your spine, leading to increased pain and discomfort.

Similarly, if you sleep on your stomach in a soft bed, this can cause extension or backward bending of your back. This extended position can also contribute to worsening lower back pain.

The softness of the mattress can further contribute to the problem. While a soft mattress may feel comfortable initially, it lacks the necessary support to keep the spine properly aligned. This lack of support can cause the spine to sag or twist, leading to increased strain on the lower back and potential aggravation of pain.

In addition to the position and mattress firmness, other factors can also contribute to worsening lower back pain during sleep. These include:

1. Poor sleeping posture: Sleeping in an awkward or unsupported position can cause stress on the muscles, ligaments, and joints of the lower back, leading to increased pain. It is important to maintain a neutral spine position while sleeping, with proper support for the head, neck, and lower back.

2. Lack of movement: Spending prolonged periods in one position can cause stiffness and muscle imbalances, which can contribute to lower back pain. It is important to change positions regularly during sleep to prevent excessive strain on specific areas of the back.

3. Existing spinal conditions: Individuals with pre-existing conditions such as herniated discs, spinal stenosis, or degenerative disc disease may be more prone to experiencing worsened lower back pain when sleeping. The combination of the position and lack of support can aggravate these conditions and lead to increased discomfort.

4. Stress and tension: Psychological factors such as stress and tension can manifest physically, leading to increased muscle tension and pain in the lower back. These factors can be further exacerbated during sleep, as relaxation may not be optimal, and the body may still hold onto stress and tension.

To alleviate lower back pain when sleeping, it is essential to consider several factors:

1. Choose a supportive mattress: Opt for a mattress that provides adequate support for your spine. Medium-firm mattresses are often recommended as they offer a balance between comfort and support.

2. Improve sleeping posture: Use pillows to support the natural curves of your spine and maintain proper alignment. For back sleepers, a pillow under the knees can help relieve lower back strain. For side sleepers, placing a pillow between the knees can help keep the spine aligned. Stomach sleeping is generally discouraged due to the strain it puts on the back, but if unavoidable, a pillow under the pelvis can help reduce extension and strain.

3. Incorporate gentle stretching and exercise: Engaging in regular exercise, particularly exercises that strengthen the core and promote flexibility, can help alleviate lower back pain. Gentle stretching before bedtime can also help relax the muscles and prepare the body for sleep.

4. Practice stress management techniques: Incorporating relaxation techniques such as deep breathing, meditation, or yoga into your daily routine can help reduce stress and tension, which may contribute to lower back pain.

It is important to note that if lower back pain persists or worsens despite these measures, it is advisable to consult a healthcare professional for a proper diagnosis and appropriate treatment plan.
