This Surprising Chilled Item Can Give You Shiny, Smooth Hair

How to Add Beer to Your Hair Routine

As the air begins to turn crisp with the changing season, I can’t help but notice the familiar struggles with my hair. My once smooth locks are now plagued with dryness, frizz and a general lack of shine. With every tug of a brush, my frustration grows. Like many, I’ve tried various products and routines, but a tried-and-true hair routine often feels elusive. After all, the same routine won’t work for everyone because there are so many factors—environment, hair type, and even diet. 

But here’s what I’ve learned: starting with the basics and experimenting with home remedies can make all the difference. Here’s a deep dive into what can bring your hair back to life, from nourishing shampoos to the unexpected benefits of beer.

If you’re feeling the same seasonal struggle, the first step in creating a hair routine that works for you is choosing the right shampoo and conditioner. Every hair type—whether straight, wavy, curly, or coiled—has unique needs, and finding products that suit yours can set the foundation for healthy hair. Hydrating shampoos are ideal for dry or frizzy hair, while volumizing formulas can help thin hair appear thicker. It’s all about what your hair needs to thrive. Once you’ve got the basics down, consider layering in other remedies to get that extra bit of shine and manageability.

<h2>Beer Rinse: Unconventional Yet Popular Choice?</h2>

Beer as a hair treatment? It may sound unusual, but beer has been used as a rinse for years due to its potential conditioning effects. Though clinical evidence on its hair benefits is limited, beer contains several nutrients including calcium, protein, selenium, and vitamins D and E which are beneficial for overall health. According to Dr. Ryan Welter, founder and CEO of Regeneris Medspa &amp; Cosmetic Surgery and the New England Center for Hair Restoration, based in Massachusetts, told Fox News Digital, "Beer doesn’t directly stimulate hair growth, but when applied as a rinse, it may provide a conditioning effect by binding to the protein structure of the hair strands, giving them a temporary boost in smoothness and shine."

<h2>How to Add Beer to Your Hair Routine</h2>

If you want to give beer a try, you can incorporate it into your hair-washing routine. It’s best to do so in moderation, perhaps once a week as overuse could lead to dryness due to its alcohol content.

After shampooing, pour a cup of flat, room-temperature beer through your hair. Let it sit for about five minutes to allow the beer’s proteins to bind with your hair.

Finish with a quick rinse to remove excess beer without washing away the conditioning effect.

While the idea of beer as a hair rinse might seem quirky, many people swear by its ability to bring out natural shine and tame frizz- though it’s best suited for occasional use.

While store-bought products offer excellent support, at-home remedies have proven benefits that are worth exploring. Many people incorporate natural ingredients to nourish their hair- think coconut oil for moisture, avocado for shine and even aloe vera for scalp health. One remedy I recently encountered was surprising but intriguing: beer.

For those not quite sold on beer, several other natural ingredients can work wonders. Essential oils like rosemary, lavender, and peppermint are popular choices. According to Dr. Brooke Jeffy, a board-certified dermatologist from Scottsdale, Arizona, previously told Fox News Digital, these oils are believed to help promote hair growth by stimulating the scalp and improving circulation.

For an alcohol-free alternative to beer try an apple cider vinegar rinse. Mixing one part apple cider vinegar with three parts water and using it as a rinse can remove buildup on the scalp, leaving your hair shiny and fresh. This mixture’s acidity helps balance the scalp’s pH and prevents excessive oil production, perfect for those struggling with greasy roots.

<h2>How Often to Wash and Oil your Hair?</h2>

Finding the right balance in your wash routine is essential. Washing too frequently can strip the hair of natural oils, leading to dryness, while infrequent washing can result in oil buildup. According to Dr. Welter, it’s essential to monitor your scalp’s health—if it’s too oily, you might experience greasiness or even acne on the scalp, while an overly dry scalp can cause flakiness and dandruff. Adjust your washing schedule based on how your scalp feels, whether it’s once a week or every few days.

<h2>Are there Any Downsides of Using Beer for Haircare?</h2>

While beer has its benefits, it’s crucial to remember the potential drawbacks. The alcohol content in beer can dry out hair, leading to increased frizz. Additionally, too much protein from beer or other protein-rich treatments can make hair feel gritty or stiff, so it’s essential to use these remedies sparingly. Dr. Welter advises monitoring your hair’s texture and moisture levels to avoid a counterproductive effect.

Every hair type is unique, and what works wonders for one person may not suit another. A little trial and error is often part of the process. Start with a solid foundation by choosing the right shampoo and conditioner, then gradually add in one or two at-home treatments, like beer or essential oils, to see how they work for you. Adjust your wash schedule according to your scalp’s needs, and give your hair the chance to find its natural balance.

Trump’s Surgeon General Pick Raises Eyebrows With Vaccine Comments And Wellness Claims

trump’s surgeon general pick raises eyebrows with vaccine comments and wellness claims

Being the most common cause of <span>dementia</span>, Alzheimer’s is a brain disorder that slowly destroys memories, thinking skills and behavioral abilities. These symptoms eventually grow enough to interfere with daily tasks. According to the Alzheimer’s Association over seven million Americans live with Alzheimer’s and that number is said to increase to 13 million by 2050. Nearly 12 million Americans provide unpaid care for people with Alzheimer’s or other dementia issues. 

However, are there certain places that have more people affected by Alzheimer’s? According to the South Texas Alzheimer's Disease Research Center, Texas has the fourth highest number of Alzheimer’s and second highest number of deaths from Alzheimer’s in the US. The Global Alzheimer’s Platform Foundation states that the Starr County is where 26% of Medicare beneficiaries come from. It is a rural Hispanic centric county in the Rio Grande City. 

<h2><span rel="noindex">What Causes Alzheimer’s Disease</span>? </h2>

<span>National Institute on Aging</span> explains that one of the biggest risk factors for Alzheimer’s is aging, most people develop Alzheimer’s when they are 65 or older with less than 10% cases happening before this. Other things include genetics, and research has shown conditions such as heart disease, stroke and high blood pressure could also be risk factors. 

Researchers do not fully understand what causes Alzheimer's. They think it's due to clumps of proteins in the brain that damage brain cells. It's likely a mix of genes, how people live, and what's around them. However, one common factor that has been observed by the researchers is that many of these families come from poor economic backgrounds. 

Being poor might play a big role because people in poorer areas often have worse air, drive more instead of walking, have more stress, and don't see people as much. She also mentioned that there might be bad things in the water, like arsenic, that can hurt the brain. The very hot weather in Texas could also be a problem, adding stress to the body. Finally, she noted that the large Hispanic population in the area might be more likely to get dementia for reasons we don't yet know.

<h2>How Socioeconomic Background of People Affects Alzheimer's </h2>

To understand how financial backgrounds could affect Alzheimer's, a 2018 study done by the International Journal of Alzheimer's Disease showed that the number of people without jobs in a region didn't seem to change how much Alzheimer's affected lifespan. This study looked at different areas in Slovakia to see if things like how much money people have, how many people have jobs, and how much education people get affect how long people might live if no one ever got Alzheimer's disease. 

However, they found that the amount of money a region had (GDP), the average pay people got, and how educated people were, did have an impact. 

More education seemed to indirectly lead to a bigger impact from Alzheimer's on lifespan, which matches what other studies have found. Surprisingly, they also found that when wages and the overall wealth of a region were higher, Alzheimer's seemed to have a bigger effect on shortening lifespan. This is different from what other studies have suggested, where more money usually means less Alzheimer's.

<span>Gardening</span> preserves cognitive function and may also help prevent <span>neurodegenerative diseases</span> like <span>Dementia</span>, Parkinson's Disease, among others. A new study, which was conducted by researchers in the UK, showed that those who grew and nurtured plants as well as lived in greener environments slowed down their <span>cognitive decline</span>. Intrestingly, there is already enough empirical evidence that shows plants reduce stress and improve memory and recall. 

It is because of this that many countries have care farms, which get their name from the way they serve people's impulses to work and connect with others. Speaking to the <em>BBC</em>, Henreitte Bringsjord, whose parents founded one of such farms, said, "My mum and dad loved farm work, and they thought about how hard it is for people with dementia to stop working and lose their social life. So, they wanted to help people with dementia become a part of life again." 

<h2>How Do Plants Help You Boost Neurological Pathways?</h2>

The study, which was published in the Journal of Environmental Psychology, stated that nature can significantly increase physical activity and social connection while reducing stress, which has multiple positive knock-on effects such as blood pressure, blood sugar control and healthy weight. According to health experts, physical activities really have immense health benefits, but gardening surcharges those.

To test the same, researchers from the University of Edinburgh investigated if there might be a link between gardening and changes in our intelligence over our lifetimes. The study compared the intelligence test scores of participants at age 11 and age 79. All the participants in the study were residents of Edinburgh and were traced throughout their lifetimes. Of the 467 people tested, almost 31 per cent had never gardened, but 43 per cent regularly did. The results showed that those who spent time gardening showed greater lifetime improvement in their cognitive ability than those who never or rarely did. "Between the ages of 79 and 90, cognitive ability, including memory, problem solving, and word fluency, generally declined across the board, but the earlier advantage of gardeners endured", researchers of the study said. 

Besides gardening, these are the activities that can also help you boost cognitive health. 

1. Physical Exercise: Improves blood flow to the brain and promotes neurogenesis.

2. Mental Exercises: Engaging in puzzles, chess, and memory games enhances problem-solving skills and memory.

3. Reading and Learning: Reading diverse materials or learning a new language strengthens neural connections.

4. Playing Musical Instruments: Enhances cognitive processing and coordination.

5. Social Interactions: Meaningful conversations and group activities stimulate cognitive and emotional processing.

6. Mindfulness and Meditation: Reduces stress and improves focus and attention span.

7. Adequate Sleep: Supports memory consolidation and cognitive function.

8. Healthy Diet: Consuming foods rich in omega-3s, antioxidants, and vitamins promotes brain health.

9. Hobbies and New Skills: Learning new skills or hobbies keeps the brain active and engaged.

10. Cognitive Training Apps: Apps designed for memory and focus training can provide structured mental workouts.

Male Menopause: Is Andropause A Reality Or A Myth?

male menopause: is andropause a reality or a myth?

A wave of social media posts has sparked curiosity around a simple bedtime habit: switching off your Wi-Fi router at night. Some claim it boosts sleep quality, reduces headaches, and even improves mental clarity. But is there any science to back this? Here's what experts say happens when you turn off your Wi-Fi for seven nights in a row.

<h4>Does Wi-Fi Radiation Affect Your Body?</h4>

Wi-Fi routers emit non-ionising radiation — a low-level form of electromagnetic radiation (EMF) — that is widely considered safe under normal household exposure. Dr Hiran S. Reddy, consultant physician, diabetologist, and critical care specialist at Gleneagles Hospital, Hyderabad, who spoke to Indian Express said that for most people, turning off the router is unlikely to cause any physiological changes.

“WiFi devices emit low-level, non-ionising radiation, which current scientific consensus deems safe at everyday exposure levels,” he explained.

However, Dr Reddy noted that people who report heightened sensitivity to electromagnetic fields — a condition known as electromagnetic hypersensitivity — may experience perceived relief from symptoms like headaches, fatigue, and sleep disturbances. But clinical evidence for this condition remains inconclusive.

<h4>Is Sleep Impacted by Wi-Fi Signals?</h4>

Dr Sudhir Kumar, consultant neurologist at Apollo Hospitals, Hyderabad, speaking to Indian Express told that most studies on Wi-Fi radiation have been conducted on animals. “There’s no conclusive evidence that Wi-Fi disrupts melatonin production from the pineal gland or interferes with human sleep,” he says.

He explains that Wi-Fi routers typically operate at 2.4 GHz or 5 GHz frequencies, which emit far less energy than a mobile phone held close to the head. At common indoor distances (1–2 metres), the signal strength drops significantly, making it unlikely to influence melatonin or sleep in any measurable way.

<h4>The Real Sleep Disruptor: <span rel="noindex">Screen Time</span></h4>

Interestingly, both doctors agree that if anything is affecting sleep, it’s likely the screen time, not the router itself. Blue light emitted from phones, tablets, and laptops interferes with the pineal gland and suppresses melatonin — the hormone that regulates the sleep-wake cycle.

“Disabling Wi-Fi might reduce digital engagement, particularly screen exposure late at night. That can indirectly improve melatonin production and sleep quality,” says Dr Reddy.

<h4>Better <span rel="noindex">Sleep Hygiene</span>, Not Less Radiation</h4>

While switching off your Wi-Fi router for seven nights won’t likely cause direct changes in your brain or body, it may lead to better bedtime routines. Less internet access could mean fewer late-night scrolls, reduced digital distractions, and an earlier wind-down — all of which support better sleep hygiene.

“Quality sleep enhances everything from mood and cognitive function to immune health,” Dr Reddy noted.

As per the 2020 study published in the International Journal of Hygiene and Environmental Health, titled: Spending the night next to a router – Results from the first human experimental study investigating the impact of Wi-Fi exposure on sleep, a night of Wi-Fi exposure doesn’t seem to cause sleep problems for healthy young men — but it might make very subtle changes in brain activity that scientists are still trying to understand.

Researchers studied how Wi-Fi exposure might affect sleep. They invited 34 healthy young men (average age around 24) to stay in a sleep lab for five nights. The first night helped them get used to the lab. Then, they had two test nights — each one following a “normal” night to compare results.

During the test nights, some participants were exposed to Wi-Fi signals (at 2.45 GHz, like your home router), while others got fake (sham) signals. The researchers didn’t tell the participants which one they were getting. Sleep was measured in two ways:

<strong>Subjective sleep: </strong>How well participants felt they slept (through a questionnaire).

<strong>Objective sleep: </strong>What actually happened in their brains and bodies during sleep (measured using special equipment called polysomnography).

The Wi-Fi signals did not cause any major or noticeable effects on:

<ul><li>How well participants thought they slept</li><li>The general structure and stages of their sleep (called sleep macrostructure)</li></ul>

However, a detailed look at brain activity showed a small change:

There was a slight decrease in brain wave activity in the alpha frequency range (8–11.75 Hz) during deep (non-REM) sleep when Wi-Fi was on. This change is called a reduction in EEG alpha power.

Wi-Fi signals didn’t seem to change how people felt they slept or the main parts of their sleep.

There was a small, measurable brain activity change, but it’s unclear if this has any real impact on health or sleep quality.

Sleep was measured in two ways:Subjective sleep: How well participants felt they slept (through a questionnaire).Objective sleep: What actually happened in their brains and bodies during sleep (measured using special equipment called polysomnography).What They FoundThe Wi-Fi signals did not cause any major or noticeable effects on:How well participants thought they sleptThe general structure and stages of their sleep (called sleep macrostructure)However, a detailed look at brain activity showed a small change:There was a slight decrease in brain wave activity in the alpha frequency range (8–11.75 Hz) during deep (non-REM) sleep when Wi-Fi was on. This change is called a reduction in EEG alpha power.What It MeansWi-Fi signals didn’t seem to change how people felt they slept or the main parts of their sleep.There was a small, measurable brain activity change, but it’s unclear if this has any real impact on health or sleep quality.
