What the experts say
Why is sleep so important to our overall health and wellness?
Sleep is not downtime. It is one of the most active and essential processes in the body, as fundamental to health as nutrition and exercise. During sleep, the brain consolidates memory and clears metabolic waste, and the body repairs tissue, regulates hormones, balances blood sugar, and strengthens immunity. When sleep is consistently short or disrupted, almost every system is affected. Poor sleep is linked to higher risks of obesity, type 2 diabetes, high blood pressure, heart disease, stroke, depression, and anxiety. People who routinely sleep too little also have a higher risk of dying early. Put simply, sleep is the foundation that everything else in health is built on.
How important is spinal alignment and support while we sleep?
Sleep is when the spine recovers. When we lie down, the load of standing comes off the spine, and the discs between the vertebrae rehydrate and regain height. This is why we are slightly taller in the morning. How well that recovery happens depends partly on how the spine is supported. When the spine is held in a relatively neutral position, muscles, joints, and ligaments can fully relax. Positions that twist or strain the neck and back are associated with waking up stiff or sore. This matters beyond comfort because pain and sleep feed each other. More than half of people with lower back pain report poor sleep, and poor sleep in turn increases sensitivity to pain, which can set up a cycle that is hard to break. Good support, particularly from a medium-firm sleep surface, has been shown to reduce back pain and improve sleep quality.
What role does the mattress play in supporting healthy sleep?
A mattress can make a meaningful difference to comfort and to back pain. The best available evidence favours medium-firm mattresses over very firm ones for comfort, sleep quality and spinal alignment. Replacing an old, worn mattress has also been shown to improve sleep quality. An uncomfortable one can undermine good sleep.
How important is the pillow to good-quality sleep?
A pillow should keep the neck in line with the spine. As a rule, side sleepers need more height and back sleepers need less. Personal comfort and waking without neck pain or stiffness are the best guides.
