5 Physically Demanding Jobs Linked to Higher Dementia Risk, New Study Reveals



New research has identified five jobs that may place workers at a higher dementia risk, challenging the adage of “healthy body, healthy mind.” Let’s learn more!

The study, published in The Lancet and led by Vegard Skirbekk, a professor of Population and Family Health at Columbia Public Health, sheds light on the potential link between physically demanding jobs and cognitive decline.

Which Jobs Are Linked to Higher Dementia Risk?

The study, conducted in collaboration with the Norwegian National Centre of Ageing and Health and the Butler Columbia Aging Center, examined the impact of occupational physical activity (PA) on dementia risk.

It defined physically demanding jobs as those requiring significant use of the arms and legs, involving activities like climbing, lifting, balancing, walking, stooping, and material handling. Occupations falling into this category included salespeople, nursing assistants, farmers, and livestock producers.

Researchers analyzed data from 7,005 participants in the HUNT4 70+ Study, one of the world’s largest population-based studies on dementia. Of these participants, 902 had been diagnosed with dementia later in life, while 2,407 had mild cognitive impairment, which doesn’t necessarily lead to dementia.

The study found that individuals in physically demanding occupations faced a 15.5% higher risk of developing dementia compared to those in low occupational PA jobs, which posed only a 9% risk. The reasons for these findings were multifaceted, encompassing both the physical and mental toll of demanding jobs.

Occupations like nursing and sales were noted for their characteristics, including a lack of autonomy, prolonged standing, strenuous physical work, rigid hours, and high stress levels.

These factors were found to have adverse effects on brain health in older individuals. Increased physical activity in later life was linked to reduced hippocampal volume and poorer memory performance.

Interestingly, previous research had identified jobs that may help preserve healthy brain function, including managerial, teaching, legal, social work, engineering, physics, medicine, dentistry, and pharmacy roles.

Dr. Skirbekk emphasized the importance of monitoring individuals with high lifetime occupational and physical activity levels due to their heightened risk of dementia.

While this study contributes to existing research on the connection between occupational PA and brain diseases, it addresses limitations seen in previous studies that relied heavily on self-reported data, which could be subject to recall bias and misinterpretation, especially in older subjects.

In conclusion, future research should explore the relationship between occupational physical activity and dementia risk in older age groups, deepening our understanding of this complex issue.

New Study Suggests Balanced Diet Better Than Vegetarian Diet for Brain Health

In a groundbreaking study published in Nature Mental Health, researchers have shed light on the relationship between dietary patterns and brain health. The study suggests that a balanced diet, comprising various food types, may be superior to a vegetarian diet in supporting mental well-being and cognitive function.

The research, which analyzed data from nearly 182,000 participants, focused on four main dietary patterns: starch-free/reduced starch, vegetarian, high-protein/low-fiber, and balanced diet. Participants’ food preferences were examined in categories such as fruits, vegetables, starches, protein, and snacks.

Optometrists Share Expert Tips to Prevent Eye Sunburn as Summer Approaches

As we gear up for the longer and sunnier days of summer, it’s essential to protect our eyes from potential harm caused by UV rays. Optometrists have shared expert advice on how to prevent eye sunburn and what to do if you experience it.

Eye sunburn, also known as photokeratitis, occurs when the sun’s UV rays damage the cornea and conjunctiva, leading to symptoms like pain, redness, sensitivity to light, and blurry vision. While discomforting, these symptoms typically resolve within 24 hours as the cornea heals.

Moreover, prolonged exposure to UV rays can also damage the retina, particularly if one stares directly at the sun. This damage, known as solar retinopathy, can cause distorted vision or even vision loss.

Unfortunately, retinal damage is often permanent due to the lack of pain receptors in the ret

Researchers Share 5 Strategies to Complete Stress Cycle and Prevent Burnout

In a recent article published by The Conversation, Theresa Larkin and Susan J. Thomas, both associate professors at the University of Wollongong, shed light on the significance of completing the stress cycle to avoid burnout and depression. Chronic stress, they warn, can lead to severe health issues including heart disease, stroke, and diabetes.

The authors delineate the three stages of the stress cycle: perceiving the threat, experiencing the fight-or-flight response driven by stress hormones like adrenaline and cortisol, and finally, achieving relief which signifies the completion of the cycle.

While stress is an inevitable part of life, remaining in the heightened state of fight-or-flight can have detrimental effects on both physical and mental health.
