The Thirsty Spine: Dehydration as a Contributor to Back Pain


Many suffer from back pain, not knowing why. One cause could be dehydration. This makes the spine stiff and reduces the cushion and flexibility between the vertebrae. This can cause more pain and tension in the back. Hydration can prevent it.

In this article, we’ll discuss how dehydration can lead to back pain. Plus, we’ll show what to do to ease it:

Causes of Back Pain

Back pain can have many different sources. It can stem from underlying medical conditions, bad habits, or lifestyle choices. Dehydration is a less known cause of back pain. It can lead to physical, emotional and mental distress. To understand and treat back pain, you must know its cause. People don’t always think of dehydration as a potential source. Yet, it can affect your spine in a serious way, so it should be taken into account.

If you suffer recurring back pain, consider all possible causes, including your fluid intake, in order to get the right treatment:

  • Underlying medical conditions
  • Bad habits
  • Lifestyle choices
  • Dehydration

Role of Dehydration

Dehydration has a big effect on the human body. It can cause physical and mental issues, like lower energy, headaches and muscle cramps. It’s proven that it can even affect our spinal health. Fluid in our body helps control joint movements in the spine. When dehydrated, this fluid is thinner, making it harder to move around the spine. This causes muscles to contract more easily and cause pain in the area near vertebrae and discs. Plus, dehydration stops us from taking in the right nutrients from food, which can worsen back pain or cause new problems.

To prevent back pain from dehydration, we need to understand how it works and drink enough fluids.

Anatomy of the Spine

To understand back issues and how dehydration affects them, it’s crucial to know the anatomy of the spine. This includes bones, discs, ligaments, muscles, and nerves. Let us dive deeper into this topic.


Vertebrae are divided into four areas. These include the cervical (neck), thoracic (mid-back), lumbar (lower back), and sacral (near the tailbone). There are 24 moveable vertebrae connected together by discs that act as shock absorbers when we move. Inter-spinous ligaments help hold the spine in position. Each vertebral body has bony protrusions called spinous processes. They support nearby muscles and tendons.

The spine holds and guards the spinal cord. Nerves run in and out of each level and send signals to different organs.

The job of bone tissue is to provide structure and protection for delicate tissues inside. The thick bone tissue of each vertebra also helps give a base for movement along our spinal axis. This is because of joint motion given by discs, ligaments, zygapophyseal joints, and synovial joints. All of this lets us move easily when we do things during the day, which makes life easier.

Intervertebral Discs

Intervertebral discs are the gliding surfaces between vertebrae. They have three parts: the outer annulus fibrosus, the inner nucleus pulposus and the endplate. The annulus is made up of 2-5 layers of tough collagen fibers and can withstand 70kg of compressive loads. It takes up 60-70% of the disc. The nucleus consists of proteins and polysaccharides, making up 30-40%. It is not solid but gel-like and it helps carry stress and absorb force while moving.

Water content is important for spinal health. It helps structures move freely without friction or pain. As we age, dehydration happens more frequently and this can lead to intervertebral discs becoming stiff and cracking. This is called Degenerative Disc Disease. To understand how dehydration impacts our bodies, it’s important to study the anatomy and hydration levels of the spine. Staying hydrated by drinking water every day is key!


Nerve roots in the spine come from different parts of the spinal cord. Every level of the spine has several nerves. These form a larger nerve, called a spinal nerve. Most nerves have three main branches. These leave the spine through small gaps around each vertebra. They spread out across the neck and back muscles. At the end, they reach body tissues and organs. These “spinal nerves” carry information from the peripheral body to the central nervous system (brain and spinal cord).

Certain tissues of your body receive oxygen-enriched blood through particular arteries. These arteries run close to the nerve pathways. This means the nerves and tissues receive nutrient-rich blood. They are also connected to the performance centers in our brains. These are the brainstem and cerebral cortex. They are important for our bodies to function well.

Dehydration can cause pain due to nerve issues. This includes disc problems like herniations or bulges. It can also include other musculoskeletal issues. It is important for people with chronic pain to consider dehydration as a possible cause. Rehydrating is simpler than operations.

Effects of Dehydration on the Spine

The spine is key for our body’s support and movement. But, dehydration can really hurt it! Discomfort, pain and even injuries can result. In this article, we explore the effects of dehydration on the spine and how it can cause back pain.

Loss of Elasticity

Dehydration can cause our spinal discs to lose elasticity and not absorb shock well. The discs between vertebrae are made of a gel-like center encircled by fibrous rings. This gel is what gives them cushioning and shock-absorbing power. When dehydrated, it can’t cushion correctly, increasing tension in surrounding muscles and ligaments, leading to pain.

If not treated, this can worsen to sciatica or degenerative disc disease. Also, the nerves may be limited in moving, sending pain signals all over. Dehydrated discs may compress nerve tissue, resulting in back pain, pins and needles feelings, and numbness.

Compression of Nerves

Dehydration can cause nerve compression. It causes intervertebral discs to shrink and thicken, creating pressure on nerve structures. This can lead to pain, tingling, or numbness in the legs and feet. Hydration can help this, but underlying spine issues should still be treated.

Dehydration also causes a lack of lubrication between vertebrae. This increases friction when moving, causing neck and lower back strain and increased risk of inflammation. People with spinal issues should stay hydrated to maintain joint fluidity and limit strain on weak tissue.

Loss of Lubrication

Dehydration reduces the cushioning fluid between vertebrae, which is made of 99% water. This fluid reduces friction between moving bones. Without it, there can be more impact injuries, wear and tear on the spine, muscle spasms, joint dysfunction, and chronic pain.

Dehydration of the discs also affects nutrition since disc cells need water to stay healthy. When disc cells die, they cannot repair themselves. This can lead to herniated discs, which put pressure on nerve roots and cause more back pain, radiating down into the legs.

Prevention and Treatment

Dehydration can cause back pain! To keep your spine healthy, you need lots of hydration. To reduce your risk of back pain, make sure you stay hydrated. Thankfully, treatments are available to reduce dehydration-related back pain. Let’s dive into prevention and treatment of this type of back pain!

Increase Water Intake

The human body needs water for survival and basic functions. But, the importance of staying hydrated goes beyond life support. Dehydration has a huge effect on back health. Drinking more water is key to both preventing and treating lower back pain due to dehydration.

Water consumption helps support healthy discs in the spine. It lubricates them and keeps them hydrated, so they can better absorb shock. Drinking plenty of water also helps with constipation, another cause of back pain. People who are active or live in hot climates may need electrolyte supplementation.

Don’t wait to be thirsty – by then it may be too late. Increase daily water intake: infants need 40-60 ounces and adults need over 100 ounces (3 liters). To get the most out of it, have a glass or two with meals throughout the day. Stay hydrated and give your discs what they need!

Improve Posture

Posture is key to reducing dehydration-related back pain. Poor posture can cause muscular imbalances, leading to compression of your spine. To improve posture, focus on postural awareness. Sit or stand with your chin parallel to the floor, shoulders relaxed and feet shoulder-width apart with a slight bend in the knees. Use chairs that fully support your back, and don’t slump forwards.

Exercises like Pilates and Yoga can help. These target weak muscles and tight muscle groups around the spine. They improve stability and flexibility, and can prevent backaches from dehydration. This can help reduce stiffness and aches from dehydration-induced joint pain in your torso.


Exercising can protect against dehydration, which brings back pain. Exercise makes you healthy and boosts blood flow to organs. When you exercise, you lose water from sweat. So, look out for signs of dehydration, like headaches, tiredness, and dry eyes and mouth. Quickly replace lost fluids after exercise with drinks or beverages with electrolytes.

When back pain is caused by dehydration, do light exercise if it does not make the pain worse. Good stretching exercises can reduce tension in the back muscles. They increase circulation and send oxygenated blood to the area. Strengthen core muscles with Pilates or yoga to improve posture and aid your spine. Lastly, do low-impact activities like swimming or walking. These will help you stay mobile while not straining your spine.


The “Thirsty Spine” hypothesis links healing to fluids. It claims dehydration is linked to slower healing and long recovery times from spinal inflammation and injury. There is controversy about how much fluid should be taken and its effect on pain. But, it is reasonable that hydration can help back pain.

Medical professionals agree that hydration is important for good spinal health. It can reduce soreness and stiffness. Drinking more water and doing a balanced exercise program can help with pain in the spine area. Anyone with back pain should visit a physical therapist or doctor.

Frequently Asked Questions
