Shocking New Research Shows Picking Your Nose Could Skyrocket Your Risk of Alzheimer's!
- Replies 15
It's a habit many might dismiss as a harmless, albeit unsightly, quirk. However, recent research suggests that picking your nose could have far more serious consequences than social embarrassment. According to scientists, this common habit could significantly increase the risk of developing Alzheimer's disease.
The connection between nose picking and dementia is a topic that has piqued the interest of the medical community, prompting calls for more extensive research. In a letter published in the American Journal of the Medical Sciences last month, researchers highlighted the scarcity of studies but pointed to existing research that identifies nose picking as a 'significant risk factor' for Alzheimer's.
The concern is that by picking your nose, you may inadvertently transfer germs from your fingers into your nasal passages. From there, these pathogens can travel to the brain, potentially causing inflammation. Alzheimer's disease is characterised by the accumulation of harmful protein deposits, known as amyloid proteins, in the brain. When the brain becomes inflamed, it produces an amyloid precursor protein that can clump together, disrupting the function of healthy brain cells.
Over time, this inflammation can damage brain cells, leading to the cognitive decline and memory loss associated with dementia. Additionally, the act of picking your nose may damage the delicate lining of the nasal wall, making it easier for micro-organisms to enter the bloodstream, potentially leading to infection and further inflammation.
The letter, authored by scientists at the Services Institute of Medical Sciences in Pakistan and the Hamad Medical Corporation in Qatar, cited ten studies that suggest a potential association between nose picking and Alzheimer's. One such study, backed by the National Institutes of Health (NIH) from the previous year, also warned of the potential link.
The researchers in the letter stated, 'Several pathogens, including those that invade the brain via the nasal epithelium... have been linked to Alzheimer's disease and have been isolated during post-mortem analysis.' They concluded that nose picking plays a role in the progression of Alzheimer's and called for more extensive case-control studies with larger sample populations to understand the association better.
Interestingly, surveys suggest that nearly every American engages in nose-picking, with many doing so four times a day on average. These germs can travel along the olfactory nerve, which connects the nose to the brain, to the olfactory bulb, an area linked to smell, and potentially cause an infection.
This research follows similar findings from a team in Australia, which also warned of a link between nose-picking and Alzheimer's. They advocated for simple intervention measures, such as regular hand washing, to reduce the risk posed by nose picking. In light of the COVID-19 pandemic, the value of hand hygiene has been underscored, with frequent hand washing and the use of hand sanitisers becoming part of our daily routines.
The Australian researchers suggested that these hygienic practices should be mandatory for those who can't resist the urge to pick their nose, labelling it an 'easy prevention step' for the disease.
Alzheimer’s disease is the most common form of dementia globally, affecting an estimated 6.7 million Americans aged 65 and older. While the exact origins of the disease are still under investigation, scientists have pointed to the buildup of amyloid plaques and tau protein tangles in the brain. Other theories suggest that damage to blood vessels in the brain, leading to reduced blood flow and unnoticed strokes, may also contribute to the development of Alzheimer's.
Given the potential implications of these findings, it's clear that a seemingly innocuous habit like nose-picking could have serious health consequences. As research continues to unravel the mysteries of Alzheimer's disease, it's worth considering the impact of our everyday behaviours on our long-term health.
So, dear readers, it might be time to rethink this common habit and adopt better hygiene practices. Not only could this protect you from the social stigma associated with nose-picking, but it could also play a role in safeguarding your cognitive health in the years to come.
