5 Preventive Health Habits That Matter Most

Physical activity helps your brain, but did you know even some sedentary activities can ward off cognitive decline? Creative crafts, reading, and puzzles such as Sudoku or Scrabble keep your brain mentally stimulated. Try word and number games rather than TV or gaming. So, when you rest your body, make sure you're still engaging your brain. Summary: New research highlights that some sedentary activities, like reading or crafting, are better for brain health than others, such as watching TV or gaming. A study of 397 older adults found that mentally stimulating and socially engaging activities support memory and thinking abilities, while passive screen time is linked to cognitive decline.This insight is crucial, as 45% of dementia cases are linked to modifiable lifestyle factors. Researchers suggest swapping passive activities for more engaging ones to protect brain health, even during indulgent holiday marathons.Key FactsCognitive Benefits: Reading and social engagement improve brain function, unlike passive screen time.Preventable Risk: 45% of dementia cases could be reduced through lifestyle changes.Healthy Swaps: Small activity changes, like breaking up TV time with reading or movement, benefit the brain.Source: University of South AustraliaIts that time of the year when most of us get the chance to sit back and enjoy some well-deserved down time. But whether you reach for the TV controller, or a favourite book, your choice could have implications for your long-term brain health, say researchers at the University of South Australia.Assessing the 24-hour activity patterns of 397 older adults (aged 60+), researchers found that the context or type of activity that you engage in, matters when it comes to brain health. And specifically, that some sedentary (or sitting) behaviours are better for cognitive function than others.When looking at different sedentary behaviours, they found that social or mentally stimulating activities such as reading, listening to music, praying, crafting, playing a musical instrument, or chatting with others are beneficial for memory and thinking abilities. Yet watching TV or playing video games are detrimental.Researchers believe that there is likely a hierarchy of how sedentary behaviours relate to cognitive function, in that some have positive effects while others have negative effects.Its a valuable insight that could help reduce risks of cognitive impairment, particularly when at least 45% of dementia cases could be prevented through modifiable lifestyle factors.In Australia, about 411,100 people (or one in every 1000 people) are living with dementia. Nearly two-thirds are women. Globally, the World Health Organization estimates that more than 55 million people have dementia with nearly 10 million new cases each year.UniSA researcher Dr Maddison Mellow says that not all sedentary behaviours are equal when it comes to memory and thinking ability.In this research, we found that the context of an activity alters how it relates to cognitive function, with different activities providing varying levels of cognitive stimulation and social engagement, Dr Mellow says.We already know that physical activity is a strong protector against dementia risk, and this should certainly be prioritised if you are trying to improve your brain health. But until now, we hadnt directly explored whether we can benefit our brain health by swapping one sedentary behaviour for another.We found that sedentary behaviours which promote mental stimulation or social engagement such as reading or talking with friends are beneficial for cognitive function, whereas others like watching TV or gaming have a negative effect. So, the type of activity is important.And, while the move more, sit less message certainly holds true for cardiometabolic and brain health, our research shows that a more nuanced approach is needed when it comes to thinking about the link between sedentary behaviours and cognitive function.Now, as the Christmas holidays roll around, what advice do researchers have for those who really want to indulge in a myriad of Christmas movies or a marathon of Modern Family?To achieve the best brain health and physical health benefits, you should prioritise movement thats enjoyable and gets the heart rate up, as this has benefits for all aspects of health, Dr Mellow says.But even small five-minute time swaps can have benefits. So, if youre dead set on having a Christmas movie marathon, try to break up that time with some physical activity or a more cognitively engaged seated activity, like reading, at some point. That way you can slowly build up healthier habits.This research was conducted by a team of UniSA researchers including: Dr Maddison Mellow, Prof Dot Dumuid, Dr Alexandra Wade, Prof Tim Olds, Dr Ty Stanford, Prof Hannah Keage, and Assoc Prof Ashleigh Smith; with researchers from the University of Leicester, and the University of Newcastle.Author: Annabel MansfieldSource: University of South AustraliaContact: Annabel Mansfield University of South AustraliaImage: The image is credited to Neuroscience NewsOriginal Research: Open access.Should We Work Smarter or Harder for Our Health?

Our eyes are incredibly precious, yet its easy to take our vision for granted until problems arise. Lets focus on proactive steps to maintain and improve our eye health. Here are some tips to keep your vision in top shape:Schedule Regular Eye Exams:One of the best ways to safeguard your vision is by scheduling regular eye exams. Comprehensive eye exams can detect vision problems early on, allowing for prompt treatment and prevention of further complications. Make it a priority to see your eye doctor at least once a year, even if you dont currently wear glasses or contact lenses.Protect Your Eyes from UV Rays: Just like your skin, your eyes can be damaged by the suns harmful UV rays. Whenever youre outdoors, especially on bright, sunny days, wear sunglasses that offer UV protection. Look for sunglasses that block 100% of UVA and UVB rays to shield your eyes from potential damage. Give Your Eyes a Break from Screens: In todays digital age, many of us spend a significant amount of time staring at screens, whether its for work, leisure, or staying connected. Prolonged screen time can lead to digital eye strain, characterized by symptoms like dry eyes, blurred vision, and headaches. To reduce eye strain, follow the 20-20-20 rule: every 20 minutes, take a 20-second break and look at something 20 feet away.Eat a Balanced Diet:Nutrition plays a crucial role in maintaining eye health. Incorporate foods rich in vitamins and antioxidants, such as leafy greens, colorful fruits and vegetables, fish high in omega-3 fatty acids, and nuts and seeds. These nutrients can help protect against age-related vision problems like macular degeneration and cataracts.Practice Good Eye Hygiene:Proper eye hygiene is essential for preventing eye infections and irritation. Wash your hands frequently, especially before touching your eyes or handling contact lenses. Follow your eye doctors recommendations for contact lens care, including proper cleaning, disinfecting, and storage.Stay Hydrated: Dehydration can contribute to dry eyes, so be sure to drink an adequate amount of water throughout the day. Aim for at least eight glasses of water daily to keep your eyes and body hydrated.Get Plenty of Sleep:Adequate sleep is crucial for overall health, including eye health. During sleep, your eyes receive much-needed rest and replenishment. Aim for 7-9 hours of quality sleep each night to help reduce eye fatigue and maintain optimal visual function.By incorporating these simple yet effective tips into your daily routine, you can help protect and preserve your precious eyesight for years to come.Your eyesight is irreplaceable, so take care of your eyes today for a brighter tomorrow!

Hot summer days are a good time for everyone to think about staying hydrated. For older adults the topic of hydration is a year-round discussion that never goes away. Its a serious issue for most seniors but doesnt get resolved because it needs to be addressed every day and cant be solved with a pill.Seniors have a very high risk for dehydration, which is one of the most frequent causes of hospitalization after the age of 65. They have a greater risk of dehydration for many reasons, including the fact that as we age, our kidneys become less efficient at conserving fluids, our sense of thirst weakens, and we are less able to adjust to changes in temperature. Some medications like diuretics, sedatives, and laxatives can also cause increased fluid loss.Dehydration can cause temporary symptoms that mimic symptoms of Alzheimers. If dementia-like symptoms seem to appear suddenly, it could be dehydration which is easily curable.Symptoms of dehydration range from minor to severe and include persistent fatigue, muscle weakness, headaches, dizziness, nausea, forgetfulness, confusion, lethargy, increased heart rate, sunken eyes, dry mouth, dark colored urine.  Urine should be clear to pale yellow. I tell my clients that if their urine is darker than pale yellow, they should head straight to the kitchen from the bathroom and drink a full glass of water.  Keeping a glass of water beside you all day to sip on rarely results in someone drinking enough fluids.  Its more effective to drink the entire glass, even if its a small glass.  Seniors cant rely on their sense of thirst to tell them when to drink water.  Scheduling a glass at each meal and/or after a bathroom visit, making sure to drink the full glass, is the best way to make sure youve gotten your full daily amount.If you have any questions, please call us at 303-444-4040.
