Rosemary often steals the headlines when it comes to strengthening hair health and stimulating hair growth. For decades, this aromatic herb has received praise for its ability to thicken hair and ward off thinning. And while rosemary certainly gets its due, there may be another herb that stands a better chance of improving hair health: ginseng. This age-old root is prized for its widespread benefits for health but has become part of the hair care regimen as a result of its strong influences on encouraging hair growth and scalp wellness.

For ages, ginseng is used as an effective adaptogen: this plant enhances general wellness, decreases stress, and boosts mental functioning. Newer research has shown another excellent advantage of ginseng: its promotion of hair growth. Most people have heard of ginseng in the Chinese traditional healing practices, but only over the last decade have researchers started to analyze it on a deeper level and look into its hair-related impacts. As it turns out, this humble root may hold the key to not just healthier hair, but more voluminous, thicker locks.

While genetics undeniably play a significant role in hair loss and thinning, factors such as stress, diet, scalp health, and circulation are all contributing elements that can exacerbate these conditions. This is where ginseng comes into play. It enhances the circulation of blood on its scalp, hence becomes fundamental in hair development and stimulating healthy growth in nourishing the scalp. That more blood flows into it thus enables the strong transport nutrients to the follicle site.

Recent studies have proven that ginseng is a potent herb that promotes hair growth. Red ginseng extract may significantly enhance hair growth, according to a study conducted in the Journal of Medicinal Food. It is crucial for those individuals who experience hair thinning or alopecia because such a discovery opens up a new window of possibilities through natural, herbal interventions.

Active ingredients of ginseng, especially ginsenosides, are considered to play a crucial role in this process. Ginsenosides enhance blood circulation towards the scalp, thereby stimulating hair follicles and increasing keratin production. The latter is a protein responsible for hair strength and structure. Moreover, the mentioned compounds inhibit the action of 5-alpha reductase, which causes male pattern baldness and female pattern hair loss. This helps ginseng in reducing the conversion of testosterone into dihydrotestosterone, a hormone that is responsible for hair loss.

Other Benefits of Ginseng for Hair Health

Aside from promoting hair growth, ginseng also offers a variety of other benefits that can help in creating a healthier scalp and stronger hair. Here are some reasons why ginseng should be part of your hair care routine:

1. Antioxidant Protection

Ginseng is full of antioxidants, which protect your hair from free radicals with harmful oxidative effects. In other words, these little molecules bring about oxidative damage, hair breakage and thinning, and unnatural aging of hair. All these problems are neutralized by powerful antioxidants in Ginseng from the inside hair cells outwards.

2. Keeps the Scalp Healthy

Ginseng has natural antimicrobial properties that keep the scalp clean and healthy. This is important in keeping conditions such as dandruff, seborrheic dermatitis, and folliculitis away from the scalp, thus impeding hair growth. A clean and balanced scalp ensures that hair follicles are not obstructed to create an optimal environment for hair to grow.

3. Hydration and Nourishment

Another property that is being provided by ginseng is to balance the scalp's natural oils. With fatty acids, it hydrates the scalp without getting greasy, making it ideal for people with both dry and oily scalps. This moisture balance will prevent hair breakage and split ends.

4. Stress Reduction

Stress is one of the most significant causes of hair loss, and ginseng is known to have an adaptogenic property. That is, it will make your body capable of resisting the effects of stress much more effectively. Ginseng would indirectly lead to a healthy scalp, as less stress would impact the body. This indirectly minimizes the chances of hair thinning due to the effect of stress factors.

How to Use Ginseng for Hair Health

If you want to add ginseng to your hair care process, then there are different ways through which you can do that. Many companies now create hair care products with added ginseng extract: shampoos, conditioners, hair masks- all of it. Thus, you'll be using ginseng without doing much.

Others prefer direct application of the ginseng-infused oils right on the scalp. However, pure ginseng oil can be quite strong, and blending it with a carrier oil like coconut or jojoba oil is suggested for the best results. Just apply this mixture to the scalp and massage it very gently to stimulate blood circulation and nourish the roots of the hair. The oil should be kept for an hour before it should be washed off the oily hair.

Another option is to create a nourishing ginseng hair mask. Combine ginseng powder with olive oil to create a mask that you can apply to your scalp. Leave it on for 20-30 minutes before rinsing thoroughly. This mask not only nourishes the scalp but also helps to repair damaged strands and improve overall hair health.

As with any hair care regimen, consistency is key when using ginseng for hair growth. To see the best results, these ginseng-based products should be used two or three times a week. One must be patient while using ginseng; hair growth is slow and gradual. If one suffers from hair thinning and scalp problems even after consuming ginseng, a visit to a dermatologist or trichologist to determine the underlying conditions will be advisable.

Whereas rosemary has long been the darling of herb enthusiasts claiming to help your hair grow, ginseng has emerged as one of the most powerful tools in the quest for healthy, thick hair. Through its properties of enhancing circulation, feeding the scalp with nutrients, and stimulating growth, ginseng proves to be an excellent remedy for people looking to get healthier-looking hair. Whether you use a commercially available product or make your own DIY treatments, you can enjoy great long-term benefits from ginseng when added to your hair care routine. The good news? It's completely natural and very effective as it supports the overall health of your scalp while fostering thicker, fuller hair.

Sleep disturbances are among the most debilitating symptoms of Alzheimer’s disease. It often appears years before significant memory decline and other symptoms.

A new study from researchers at the University of Kentucky suggests that this sleep loss may not be permanent.

Instead, it could be driven by an immune response in the brain that may be reversible, sparking hope for new treatments.

Published in the journal Alzheimer’s & Dementia, the study found that brain immune cells called microglia, rather than amyloid plaques themselves, are the primary cause of sleep disruption in Alzheimer’s disease.

In mouse-based trials, researchers were able to restore more than two hours of sleep per day by temporarily removing these immune cells, without reducing amyloid plaques.

Can Sleep Be Restored In Alzheimer’s Patients?

For years, scientists believed that sleep problems in Alzheimer’s were caused by the accumulation of amyloid plaques or the gradual death of brain cells. However, this study points in a different direction.

Researchers discovered that when amyloid plaques begin forming in the brain, they activate microglia, the brain’s resident immune cells.

Instead of protecting the brain, these cells cause inflammation that keeps brain circuits active, preventing sleep.

Using a drug called pexidartinib (PLX3397), the researchers temporarily depleted around 87% of microglia in Alzheimer’s mouse models.

This restored over two hours of daily sleep, particularly non-rapid eye movement (NREM) sleep, which is essential for tissue repair, memory strengthening, and clearing waste products from the brain.

Notably, the improvement occurred without changing amyloid plaque levels, suggesting that inflammation is manageable.

'Paradigm Shifting' Findings

Lead researcher Dr. Shannon L. Macauley, associate professor of physiology at the University of Kentucky College of Medicine, said, “Basically, we showed that it is not the plaques themselves, or solely dysfunctional neurons, that cause sleep loss but actually microglia.

Microglia are immune cells that, when they respond to plaques, kick off this elaborate cascade of inflammation, as if the microglia are partying all night, and keeping the brain awake.”

She also highlighted why losing restorative sleep can accelerate disease progression.

“That restorative sleep is super important for physical repair, learning and memory and washing out the toxins of the day. When Alzheimer’s patients lose this stage, they lose their brain’s primary cleaning cycle, creating a feed-forward loop that may drive further damage,” she explained.

First author Dr. Nicholas J. Constantino said one of the biggest surprises was that sleep problems did not worsen as amyloid plaques increased.

“I expected that as plaque burden became more severe, sleep disruption would also worsen. The disruptions in sleep… did not worsen by 18 months, despite more than double the amount of plaque burden,” Constantino said.

Why Do Alzheimer’s Patients Lose Sleep?

Poor sleep and Alzheimer’s create a vicious cycle. Sleep deprivation reduces the brain’s ability to clear amyloid-beta and tau proteins, which can accelerate disease progression, while worsening sleep.

Sleep disturbances affect up to half of people living with Alzheimer’s disease. The disease disrupts sleep due to various reasons:

Overactive microglia: As shown in the new study, immune cells become chronically activated by amyloid plaques, releasing inflammatory signals that keep the brain in a heightened state of activity.

Damage to sleep-regulating brain regions: Alzheimer’s progressively affects areas like the hypothalamus and brainstem that regulate the sleep-wake cycle.

Loss of NREM sleep: Due to lack of deep sleep, the brain’s ability to clear metabolic waste, including amyloid plagues weakens.

Circadian rhythm disruption: Degeneration of the brain’s internal clock leads to broken sleep and daytime drowsiness. This fuels confusion and agitation associated with the disease.

Obesity has always been considered as one of the contributors to heart disease, diabetes, and stroke.

Now, growing research suggests that excess body fat, particularly in your 40s and 50s, may also accelerate brain aging and raise the risk of long-term cognitive decline.

Researchers say that obesity is not just linked with memory problems but also to significant changes in the brain structure.

Maintaining a healthy weight, especially during midlife, could help prevent memory problems and overall cognitive decline.

Higher BMI Linked To Faster Brain Aging

A recent study by researchers at the University of Georgia followed more than 8,200 adults aged 50 years and older for nearly 24 years.

The researchers found that individuals whose body mass index (BMI) increased over time experienced faster declines in cognitive performance than it would with normal aging. Excess body weight affected several aspects of cognition, including memory, planning, decision-making, problem-solving, emotional regulation, and concentration.

Lead author Dr. Claire Sexton (University of Georgia College of Public Health) said, "Maintaining a healthy body weight throughout adulthood may be an important strategy for preserving cognitive health later in life."

The study adds to the evidence that preventing weight gain throughout adulthood could become crucial for reducing dementia risk.

How Does Obesity Affect The Brain?

Chronic Inflammation

Obesity causes chronic low-grade inflammation, which can potentially damaging neurons essential for learning and memory.

Insulin Resistance

The brain relies on glucose for energy. Insulin resistance, common in obesity, may impair how brain cells use glucose, affecting memory and thinking.

Reduced Blood Flow

Obesity increases the risk of hypertension, atherosclerosis and vascular disease, reducing blood supply to brain tissue and potentially accelerating cognitive decline.

Visceral Fat

Experts believe visceral fat, the fat surrounding internal organs, may be more damaging than body weight alone. It produces inflammatory chemicals linked to brain changes and dementia risk.

Growing Evidence

The latest findings are supported by several years of research. A large review published in Practical Neurology concluded that obesity is associated with smaller hippocampal volume, temporal lobe atrophy, mild cognitive impairment and increased Alzheimer's disease risk.

Some studies have suggested that obesity during midlife may nearly double the risk of developing Alzheimer's disease or dementia later in life.

Another review on obesity and aging reported that higher BMI is associated with poorer verbal memory, slower information processing and reduced executive function, particularly among older adults.

In January 2026, researchers also used genetic analyses to suggest that obesity and high blood pressure may directly contribute to dementia.

Can The Risk Be Reduced?

With a few lifestyle improvements, overweight and obese individuals can maintain a healthy BMI, reducing the risk of faster brain ageing and cognitive degradation. Experts recommend focusing on overall metabolic health rather than the number on the weighing scale alone.

Maintaining a healthy weight, regular exercise, controlling blood pressure, cholesterol and diabetes, following a Mediterranean diet, getting adequate sleep, remaining socially and mentally active can help maintain a healthy body weight.

Living with someone who has hepatitis can be worrying. People tend to immediately wonder whether they are at risk simply by sharing meals, hugging, or living under the same roof.

Fortunately, the answer depends on the type of hepatitis, and in most cases, everyday household contact does not spread the virus.

Dr. Shalimar, Prof. Department of Gastroenterology, AIIMS explains, "Hepatitis means inflammation of the liver. There can be many causes, but viral hepatitis is one of the most common. There are different hepatitis viruses, including A, B, C, D, and E. Some cause acute illness, while others can lead to long-term liver damage, including cirrhosis and liver cancer."

Experts say misinformation surrounding hepatitis often leads to unnecessary fear and stigma, causing patients to feel isolated. Understanding how different hepatitis viruses spread can help families protect themselves without avoiding normal interactions.

Can You Get Hepatitis By Living With Someone?

Dr Nanda Kishore M, Gastroenterology, Athulya Geriatric Care Hospital, answers our question, "No, Hepatitis is not a communicable disease that spreads through everyday contact such as hugging, holding hands, coughing, or sneezing."

For most forms of hepatitis, the answer is no. However, hepatitis B is spread through contact with infected blood and certain body fluids. Household transmission is possible, but it generally occurs when infected blood enters another person's bloodstream.

Possible household risks include sharing:

• Razors
• Toothbrushes
• Nail clippers
• Glucose monitoring devices
• Any item contaminated with blood

Dr. Kishore says that the mode of transmission largely depends on the type of hepatitis infected.

He says, "Hepatitis A and E are predominantly spread via means of contaminated food and water, while Hepatitis B and C are transmitted through infected blood and certain bodily fluids."

Hepatitis B is preventable by vaccine. Household members of someone with chronic hepatitis B are usually advised to get tested and vaccinated if they are not already immune.

Dr. Shalimar says, "For hepatitis B, current treatment controls the infection, and newer therapies under development offer hope for a functional cure in the future. Vaccination has dramatically reduced hepatitis B in many parts of the world. Expanding vaccination coverage remains one of the most effective ways to prevent the disease."

Living with a hepatitis infected individual is generally safe given that basic hygiene and recommended precautions are followed strictly. Understanding these facts helps reduce unnecessary fear and stigma associated with it.

Importance of Screening & Prevention

Living with someone who has hepatitis does not mean you need to keep your distance. Instead, focus on practical precautions:

• Never share personal items that may come into contact with blood.
• Cover cuts and wounds.
• Wear disposable gloves while cleaning blood spills.
• Practice good hand hygiene.
• Ensure hepatitis B vaccination if recommended.
• Attend regular medical follow-ups if advised by your healthcare provider.

Dr. Ankur Jain, Associate Director & Unit Head, Gastroenterology, Hepatology & Endoscopy, Max Hospital, Dwarka, explains, "Hepatitis B and Hepatitis C continue to affect millions of people worldwide and remain major causes of liver cirrhosis and liver cancer. Individuals with a history of blood transfusions before routine screening, unsafe injections, or other risk factors should discuss screening with their physician.

He adds, "The liver has an extraordinary capacity to heal, but only if we identify problems early and address the underlying causes. Prevention, timely screening, and simple lifestyle modifications remain our most powerful tools in reducing the growing burden of liver disease in India."
