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.

An international team of researchers has developed an artificial intelligence (AI)-based tool that can significantly improve care for glaucoma -- a leading cause of irreversible blindness worldwide, according to a study published in The Lancet Primary Care journal today.

Researchers led by those from the University of Lisbon in Portugal found that the AI-based screening tool halved the number of unnecessary referrals for glaucoma.

The study, released during the Glaucoma Awareness Week, also showed an accuracy level at par with human eye doctors.

"The high accuracy at excluding people without glaucoma is especially important, as false alarms can lead to unnecessary hospital visits, patient anxiety, and added strain on healthcare services," the researchers said.

According to the researchers, AI-based screening could:

• support earlier detection,
• reduce unnecessary specialist referrals,
• prevent avoidable vision loss,
• can be integrated into routine primary care in a cost-effective way

Key Findings

The study was carried out at a single screening center in Lisbon, Portugal, in 2023.

The experts screened 671 adults aged 55-65 for glaucoma via the AI tool, analyzing images of the eyes. The images were then independently graded by six glaucoma experts.

The AI-tool:

• referred 66 people (9.8 percent) vs 118 referrals (18.0 percent) by the eye doctors,
• diagnosed glaucoma in 40 participants (6.4 percent).
• It correctly identified 78 percent of people who truly had glaucoma, vs 75 percent identified by the eye doctors
• Correctly ruled out the disease in 95 percent of people, vs 91 percent by eye doctors

While modelling studies suggest that screening could substantially reduce glaucoma-related visual impairment and blindness, barriers include the need for specialised diagnostic equipment and trained personnel, particularly in low- and middle-income countries, and the intrinsically low positive predictive value of screening tests.

In such a scenario, the new study showed that "AI may provide a more viable option than population-wide screening", which may seem impractical.

What Is Glaucoma?

Glaucoma is a chronic disease that affects an estimated 80 million individuals globally, according to the World Glaucoma Association.

It is a progressive, degenerative disorder of the optic nerve that produces characteristic visual field damage.

The disease stems from a long asymptomatic phase, resulting in substantial underdiagnosis and delayed treatment.

Even in high-income countries, up to 50 percent of individuals with glaucoma remain undiagnosed, frequently presenting moderate to advanced disease at first detection.

By the year 2040, it is estimated that there will be 22 million individuals worldwide who are blind from glaucoma.

When to see a doctor for glaucoma:

• Vision suddenly gets blurry
• Severe eye pain
• Headache
• Nausea
• Vomiting
• Rainbow-colored rings or halos around lights

In adults, long periods of sleep deprivation has been linked to problems such as weakened immunity, weight gain, depression, and an increased risk of dementia. However, scientists are now paying closer attention to how sleep affects the brain much earlier in life.

However, a new University of North Carolina School of Medicine study suggests that disrupted sleep during early childhood may interfere with key stages of brain development and asl well as increase the risk of developing autism.

Why Sleep Matters For The Developing Brain

Sleep plays a crucial role in helping these synapses form and strengthen. During sleep, the brain organizes and stabilizes these neural connections, shaping the foundation for future brain function. If sleep is repeatedly disrupted during this delicate stage of development, the process may be affected.

Frequent waking or sleep disturbances could interfere with how these neural connections are formed, potentially influencing behavior and cognitive abilities later in life.

The Link Between Sleep And Autism

“The unique effects of sleep loss during development are largely unexplored,” Diering said. “Our data show that babies and children are more vulnerable to the negative effects of sleep disruption. We also found that sleep loss during this crucial period of time can negatively interact with underlying genetic risk for autism spectrum disorder.”

Sleep problems are already known to be common in people with autism. In fact, sleep disruption has been reported in more than 80 percent of individuals with autism spectrum disorder. However, researchers have long debated whether these sleep issues are a cause of the disorder or a consequence of it. Understanding how sleep interacts with brain development could help scientists detect autism earlier and potentially develop new treatment strategies.

Studying Sleep Disruption In Early Life

In earlier work conducted in 2022, researchers examined how sleep disruption during early life might interact with genetic factors linked to autism. Using mouse models, they disrupted sleep during the third week of life, a developmental stage roughly comparable to ages one to two in humans.

The study found that sleep disruption during this period produced long lasting behavioral changes. Male mice that were genetically vulnerable to autism showed deficits in social behavior later in life. These results suggested that sleep disruption during critical stages of development may interact with genetic risk factors in ways that shape long term behavior.

Younger Brains Respond Differently To Sleep Loss

To investigate further, researchers studied how developing and adult mice respond differently to sleep deprivation.

Using specially designed housing systems equipped with sensitive sensors, scientists tracked the animals’ breathing and movement. This allowed them to determine when the mice were awake and when they were asleep.

The researchers observed that adult mice were able to compensate for lost sleep. After experiencing sleep deprivation, the adults increased their sleep later during their normal active period. This process, known as sleep rebound, allowed them to recover some of the lost rest.

Younger mice behaved very differently. They showed no sleep rebound at all, meaning they did not compensate for the sleep they had lost. This finding suggests that younger brains may be far more vulnerable to the effects of sleep disruption.

The consequences were also visible in cognitive performance. Sleep deprived young mice performed poorly on learning and memory tasks, while adult mice were significantly more resilient after losing sleep.

Changes At The Level Of Brain Synapses

The results showed that sleep deprivation in young mice significantly altered the formation of synapses. These changes were not seen in adult mice. “This now provides one of the largest and most comprehensive datasets to examine the molecular effects of sleep loss across the lifespan,” Diering said.

Potential Future Treatments

“Development is not something that one can go back and do again,” Diering said. “Sleep is important for the entire life and especially during development. Understanding what we know now will place greater emphasis on understanding sleep issues in ASD and could lead to an important therapeutic avenue to treat ASD and other developmental conditions.”

The findings highlight an important message for parents and caregivers. During early childhood, healthy sleep patterns may play a critical role in shaping the brain for years to come.

Using amphetamines, cocaine and cannabis can significantly increase your risk of having a brain stroke particularly among younger adults, according to a new University of Cambridge analysis

The findings highlight how recreational drug use may contribute to a preventable health risk, especially among people under the age of 55.

Megan Ritson, a stroke genetics researcher at the University of Cambridge and lead author said the results provide strong evidence linking certain drugs to stroke risk.

“These findings provide compelling evidence that drugs like cocaine, amphetamines, and cannabis are causal risk factors for stroke,” Ritson noted.

A stroke occurs when blood flow to part of the brain is interrupted. This can happen when a blood vessel becomes blocked by a clot, known as an ischemic stroke, or when a blood vessel bursts and causes bleeding in the brain, known as a hemorrhagic stroke. Both types can lead to serious brain damage and can be life threatening.

Amphetamines Associated With The Highest Risk

When researchers combined data from eight previous studies, they found that recreational amphetamine use was associated with more than double the risk of stroke across all adult age groups. For individuals under the age of 55, the increase was even greater. In this group, amphetamine use was linked to nearly triple the risk of stroke compared with people who do not use the drug.

Across all age groups, the analysis found that amphetamine use increased the risk of ischemic stroke by 137 percent and hemorrhagic stroke by 183 percent. These figures reflect relative risk, meaning the probability of stroke is higher among users compared with non users.

Cocaine Shows A Similar Pattern

The analysis showed that cocaine use nearly doubled the risk of stroke of any kind and more than doubled the risk of hemorrhagic stroke. Additional genetic investigations were conducted alongside the main analysis to better understand whether the relationship might be causal rather than simply linked to other lifestyle factors.

Eric Harshfield, a genetic epidemiologist at the University of Cambridge, said the findings suggest the drugs themselves may play a direct role. “Our analysis suggests that it is these drugs themselves that increase the risk of stroke, not just other lifestyle factors among users,” Harshfield said.

Cannabis Linked To Smaller But Significant Risk

Among people under the age of 55, cannabis use was linked to a 14 percent increase in stroke risk. Although the increase is lower than that associated with stimulant drugs, researchers say it remains important because cannabis is widely used.

Opioids Showed No Clear Association

A Preventable Health Risk

The researchers also note that many of the studies included in the analysis relied on participants reporting their own drug use. Because of this, other lifestyle factors could potentially influence the results. Further research will be needed to better understand the biological mechanisms involved and how different patterns of drug use may affect stroke risk. Still, scientists say the evidence now available provides an important foundation for future public health strategies.

“These findings give us stronger evidence to guide future research and public health strategies,” Ritson said.
