Practicing simple breathing exercises like yoga and meditation can help reduce stress and bring balance to the body. Recent studies suggest that breath work may also lower the risk of Alzheimer’s disease.

A study done at USC Leonard Davis School of Gerontology and published in Scientific Reports found evidence that both young and old adults can reduce factors that increase the risk of Alzheimer’s disease.

The scientists discovered that breathing exercises that slow down heart rate can also decrease the buildup of amyloid and tau in the blood.

How is the study done?

A study with 108 participants, half aged 18-30 and half aged 55-80, were asked to inhale and exhale for a count of five, twice a day for four weeks. They were hooked up to a heart monitor. One group thought of calming things while the other paced their breathing with a pacer.

The breathing exercises changed the heart rate of the volunteers. The heart rate changed more during each exercise. The breathing exercises also lowered the levels of amyloid-beta peptides and tau protein in the blood of people in the study over four weeks.

This is important because scientists believe that Alzheimer’s disease is caused by abnormal tau proteins and amyloid beta peptides.

If amyloid beta builds up in the brain, it can cause damage that leads to Alzheimer’s disease. Unfortunately, there is no cure for this disease at the moment and it is the most common type of dementia.

It seems like our breathing affects our heart rate, which impacts the nervous system and protein production in the brain. The buildup of amyloid-beta proteins in the brain will then potentially cause Alzheimer’s disease. Research suggests that even healthy adults with amyloid beta 40 and 42 in their blood may be at risk of developing Alzheimer’s later on.

At the end of the study, researchers found lower levels of key proteins associated with Alzheimer’s disease in their blood

Breathwork and the brain

The researchers think that changing how we breathe could affect the build-up of Alzheimer’s proteins in the brain, but they need to do more work to find out exactly how this happens and how it affects our risk of getting dementia. The study found that a system in our body called the noradrenergic pathway, which is related to our “fight or flight” response, might be involved, but more study is needed.

The study also found that when heart rate variation increases, peptides decrease. However, we still don’t know why this happens. But we need more research to understand the mechanism and how it can help manage the risk of Alzheimer’s.

Larger studies could provide clarification

Although the study has yielded promising results, it is important to note that the sample size was limited. Therefore, it is recommended that larger scale studies be conducted in order to accurately determine the efficacy of the treatment or intervention being studied. This will allow for a more comprehensive analysis of the data and a better understanding of the potential benefits or drawbacks of the approach being investigated.
