Follows the Herpes virus causing neuro-inflammation and accelerated brain atrophy theory.

Would be good to see a similar study in non-shingles and other Herpes patients esp HSV-1 (oral herpes)

Also so dope that Wales can do a population based study like this just based on birth dates.

Shingles Vaccine Might Lower Dementia Risk

New research shows the shingles vaccine (Zostavax) could do more than just prevent painful rashes — it might also help protect against dementia.

A study in Wales found that older adults who got the vaccine had a 20% lower risk of dementia over seven years. Interestingly, women seemed to benefit even more than men.

The Brain Ages Faster Than We Thought — Starting at 44

New research reveals that brain aging doesn’t happen gradually — it accelerates sharply starting around age 44, peaks near 67, and then slows down by 90. This midlife brain shift is linked to neural network instability and even insulin resistance in brain cells.

Only 5 Minutes? That’s Enough to Boost Health

New research shows that just five minutes of simple bodyweight exercises a day like slow squats, wall push-ups, or chair reclines can improve strength, flexibility, and even mood.

After just four weeks, even people with sedentary lifestyles saw real results. No gym, no gear just short, slow movements focusing on eccentric muscle contractions (like lowering into a chair slowly).

This challenges the idea that workouts need to be long or intense. A few minutes here and there might be all it takes to feel better both physically and mentally.

HPV and Your Heart? A Surprising Link

we all know HPV as the virus behind some cancers but what if it’s hurting your heart too?

A new analysis of 250,000 patients found that people with HPV have a 40% higher risk of heart disease, and double the risk of coronary artery disease. Even after factoring in age, lifestyle, and meds, the risk stayed high.

Researchers think chronic inflammation from the virus may be the culprit. Some are even asking: could the HPV vaccine help protect the heart, not just prevent cancer?

It’s early, but this could reshape how we think about infections and heart health.

Did you know chewing gum might expose you to microplastics?
A recent study found that both regular and “natural” gums can release hundreds of microplastic particles into your saliva — most within the first 2 minutes of chewing.

If you chew gum regularly, that could mean swallowing up to 30,000 plastic particles a year.

The health impact is still unclear, but this discovery highlights yet another everyday source of microplastic exposure — one most of us never considered.

The Gut-Brain Axis

🔴 Did you know your gut talks to your brain?
Gut bacteria produce stuff like serotonin that affects your mood. That’s why what you eat impacts not just your body, but your mental health too!

📍The gut microbiome communicates with the central nervous system through the gut-brain axis, a bidirectional pathway involving neural, hormonal, and immune mechanisms. Gut bacteria produce neurotransmitters like serotonin, which are crucial for mood regulation. Imbalances in this system can contribute to mental health issues such as depression

Why Does One Nostril Always Feel Blocked? The Science Behind Nasal Cycling

Ever noticed that one nostril always seems clearer than the other? This isn’t just your imagination, it's called the nasal cycle. Your nostrils naturally alternate between being congested and clear every few hours. This happens because your body intentionally directs blood flow more to one side, allowing the other nostril to rest and recover moisture

Is Modern Living Causing a Diabetes Crisis?

Your daily habits—morning coffee, late-night scrolling, and even breathing polluted air—could be quietly causing insulin resistance, the root of Type 2 diabetes. A recent groundbreaking study in The Lancet Diabetes & Endocrinology (March 2025) shows that environmental factors and our modern lifestyle (poor diet, air pollution, disrupted sleep patterns) are weakening our body's insulin response, pushing even healthy people closer to diabetes

Did you know your gut bacteria can influence the quality of your sleep? Recent research suggests a significant relationship between gut microbiome diversity and improved sleep patterns. Individuals with a more diverse range of gut microbes were found to experience deeper sleep, shorter sleep onset, and fewer sleep disturbances. This discovery highlights how maintaining a healthy gut microbiome isn't only important for digestive health-it might also play a critical role in achieving restful, quality sleep

Gut microbiome diversity is associated with sleep physiology in humans

The human gut microbiome can influence health through the brain-gut-microbiome axis. Growing evidence suggests that the gut microbiome can influence sleep quality. Previous studies that have examined sleep deprivation and the human gut microbiome have yielded conflicting results. A recent study found that sleep deprivation leads to changes in gut microbiome composition while a different study found that sleep deprivation does not lead to changes in gut microbiome. Accordingly, the relationship between sleep physiology and the gut microbiome remains unclear. To address this uncertainty, we used actigraphy to quantify sleep measures coupled with gut microbiome sampling to determine how the gut microbiome correlates with various measures of sleep physiology. We measured immune system biomarkers and carried out a neurobehavioral assessment as these variables might modify the relationship between sleep and gut microbiome composition. We found that total microbiome diversity was positively correlated with increased sleep efficiency and total sleep time, and was negatively correlated with wake after sleep onset. We found positive correlations between total microbiome diversity and interleukin-6, a cytokine previously noted for its effects on sleep. Analysis of microbiome composition revealed that within phyla richness of Bacteroidetes and Firmicutes were positively correlated with sleep efficiency, interleukin-6 concentrations and abstract thinking. Finally, we found that several taxa (Lachnospiraceae, Corynebacterium, and Blautia) were negatively correlated with sleep measures. Our findings initiate linkages between gut microbiome composition, sleep physiology, the immune system and cognition. They may lead to mechanisms to improve sleep through the manipulation of the gut microbiome.

In continuation of the post about posture.

To determine the state of posture, you can stand with your back to the wall and press the back of your head, shoulder blades, buttocks, and heels tightly against it. If it is uncomfortable to hold such a position, then the posture is incorrect.

I will write recommendations in the next post.

I want to say a few words about posture 🩻 📏

The correct posture looks like this: the head is raised high, the chin is exposed forward, the body is straightened, the chest is deployed, the shoulders are at the same level and slightly pulled back, the stomach is pulled up. If you look at a person from behind, the head, neck and spine should form a straight vertical line.

Why do you need proper posture? If the posture is correct, the load distribution is uniform. This allows you to save joints, protect cartilage tissue from premature wear. A straight back, straightened shoulders promote full-chest breathing, and gas exchange occurs more efficiently in the lungs.

I will continue in the next caste.

Do exercises in the morning!🤸

The human body is not able to fully wake up when the alarm clock rings. And even at the moment when you have already got out of bed, all internal organs and systems still continue to "rest".

During sleep, blood circulation slows down, metabolism slows down, and mental activity decreases. That is why, during awakening, a person feels a slight lethargy. He has decreased performance, both physically and mentally. In the morning, the reaction rate is significantly worsened.

This condition can last (depending on individual characteristics) from 1 to 3 hours. To fully wake up and shake off such "inhibition", it is necessary to develop joints and muscles. In other words, you just need to do some exercises.

Sleep 7-9 hours every day💤

Sleep affects performance, emotional balance, brain and heart health, immune system, creativity, vitality, and even weight. In a dream, the body gains strength, and the brain processes the information received during the day. If there is not enough sleep or it is of poor quality, the brain does not have time to do night work and the person may feel sluggish and unable to concentrate.
Hello everyone I decided to publish simple ways and habits to be healthy! Let's start with the simplest thing that we do every day, but not so much.

Drink more water 💧
An adult needs about 8 glasses of liquid per day. This amount includes all drinks and liquid products (for example, soups). But it is better to replace strong tea and coffee with clean water. Try to get used to drinking a glass of water immediately after waking up: this allows you to wake up faster yourself and "wake up" the gastrointestinal tract.
