To our knowledge, this study is the first to show a relationship between time spent in the supine sleep position and dementia.
Sleep on your side to boost brain power
Concerned about your brain health? Side sleeping could help keep you sharp and possibly reduce your dementia risk.
Researchers suggested the supine position reduces blood movement in and out of the brain, and reduces lung efficiency, resulting in lower brain oxygenation.
Research shows that a side-sleeping position improves the brain's glymphatic system, which is the cleansing system that removes waste from the brain. This waste is believed to contribute to the development of Alzheimer's disease and other neurodegenerative diseases.
Specifically, sleeping on the side or back is considered more beneficial than sleeping on the stomach. In either of these sleep positions, it's easier to keep your spine supported and balanced, which relieves pressure on the spinal tissues and enables your muscles to relax and recover.
Sleeping on your stomach is by far the worst position for your health. It's particularly bad for your spine if you're turning your head to one side to breath. Keeping the neck in a twisted position all night can lead to neck pain from muscle strains.
Sleeping on your left side can help naturally open the airways and make breathing easier. You may also find relief if you rest on your right side, but doctors believe sleeping on your left side to be more effective. It's also the recommended sleeping position for people with sleep apnea.
Administration: The examiner reads a list of 5 words at a rate of one per second, giving the following instructions: “This is a memory test. I am going to read a list of words that you will have to remember now and later on. Listen carefully. When I am through, tell me as many words as you can remember.
Damage to particular left brain regions can cause people to become apathetic, lose their inhibitions, or show no consideration for the feelings of others. With Alzheimer's disease, memory-related areas in the lower and back parts of the brain tend to be affected first.
Many people affected by dementia are concerned that they may inherit or pass on dementia. The majority of dementia is not inherited by children and grandchildren. In rarer types of dementia there may be a strong genetic link, but these are only a tiny proportion of overall cases of dementia.
Low lighting can increase shadows, which may cause the person to become confused by what they see. They may experience hallucinations and become more agitated. Noticing stress or frustration in those around them may cause the person living with dementia to become stressed as well.
Alzheimer's disease, the most common dementia diagnosis among older adults. It is caused by changes in the brain, including abnormal buildups of proteins known as amyloid plaques and tau tangles.
Semantic memory is at first impaired in the language of AD patients, affecting verbal fluency and naming. Semantic loss in AD may occur several years prior to diagnosis. The hippocampus is essential to the consolidation of information from short-term to long-term memory.
The Mini-Cog test.
A third test, known as the Mini-Cog, takes 2 to 4 minutes to administer and involves asking patients to recall three words after drawing a picture of a clock. If a patient shows no difficulties recalling the words, it is inferred that he or she does not have dementia.
You have trouble following a conversation. You find it hard to make decisions, finish a task or follow instructions. You start to have trouble finding your way around places you know well. You begin to have poor judgment.
The Self-Administered Gerocognitive Exam, known as SAGE, is a brief, pen-and-paper cognitive assessment tool designed to detect the early signs of cognitive, memory, or thinking impairments. The test evaluates your thinking abilities. This can help your doctors understand how well your brain is functioning.
Reflux and heartburn: If you suffer from heartburn, sleeping on your right side can make symptoms worse, Salas says. That's true for people who have gastroesophageal reflux disease (GERD) and for people who have heartburn for other reasons, such as pregnant women. Flip to your left side to cool the burn.
Cons: Sleeping on the left side can put pressure on the stomach and lungs, and affect blood flow, so it is best to switch it up… or you may experience numbness in your arms from resting on one for too long.
This muscle is more relaxed during sleep, and it controls whether or not gas present in the large intestine is released. This muscle also spontaneously relaxes multiple times per hour in the morning. As a result, passing gas overnight or in the morning is common.
Research reveals more women prefer to sleep on the left side of the bed than the right - and the reason why is super cute.
Sleeping with your legs lifted relieves back pain
Sleeping on your back with your legs laid straight puts pressure on your lower back, which may result in more back pain over time. By elevating your legs as you sleep, you will take some of the pressure off, relieving your lower spine.
