Do you find yourself struggling to fall asleep or stay asleep throughout the night? You’re not alone. Insomnia is a prevalent sleep disorder that impacts millions of individuals worldwide, disrupting their ability to get sufficient rest. While sleep requirements differ from person to person, most adults need at least seven hours of quality sleep each night. If you’re frequently tossing and turning, certain natural remedies and lifestyle changes may help restore a restful night’s sleep.

Mindfulness Meditation for Deep Relaxation

Practicing mindfulness meditation, which involves slow and steady breathing while observing thoughts and sensations without judgment, can significantly enhance relaxation. This method is known to reduce stress, improve focus, and promote a sense of calm, all of which contribute to better sleep. A study conducted in 2011 revealed that individuals who practiced mindfulness meditation experienced notable improvements in their sleep patterns. Taking 15 minutes each morning or evening to meditate, or following a guided session online, can help create a soothing pre-sleep routine.

Mantra Repetition for Mental Calmness

Repeating a mantra or a positive affirmation before bed can help quiet the mind and induce relaxation. A 2015 study found that homeless women who engaged in mantra repetition experienced reduced symptoms of insomnia. Select a calming phrase, such as “I am at peace” or "Sleep comes naturally to me" and repeat it mentally or aloud before bedtime to help ease your mind and transition into sleep more smoothly.

Yoga to Relieve Stress

Yoga has been linked to enhanced sleep quality, reduced stress, and improved mental clarity. Styles like yin yoga and restorative yoga focus on slow movements and controlled breathing, making them ideal for relaxation. Incorporating yoga into your weekly routine, or practicing a short session before bedtime, can prepare both your body and mind for restful sleep.

Exercise for Healthier Sleep Patterns

Engaging in regular physical activity not only benefits overall health but also enhances sleep quality. A 2015 study found that individuals who exercised for at least 150 minutes per week reported fewer symptoms of insomnia, along with decreased anxiety and depression levels. Aim for at least 20 minutes of moderate exercise daily, but try to complete workouts earlier in the day to avoid overstimulation before bedtime.

Massage Therapy for Relaxation

Massage therapy has been found to improve sleep quality by reducing stress, pain, and anxiety. While professional massages can be beneficial, self-massage or help from a partner can also promote relaxation. Focus on gentle techniques to calm the body and mind before heading to bed.

Magnesium for Muscle Relaxation

Magnesium is an essential mineral that helps relax muscles and alleviate stress, thereby promoting restful sleep. A 2012 study found that individuals who took 500 mg of magnesium daily for two months experienced significant improvements in sleep quality. Magnesium can be taken as a supplement or absorbed through a warm bath infused with magnesium flakes.

Lavender Oil for a Calming Effect

Lavender is widely recognized for its ability to improve mood and encourage relaxation. Studies suggest that lavender oil capsules can enhance sleep quality, particularly in individuals suffering from anxiety or depression. Diffusing lavender oil in the bedroom or adding a few drops to your pillow can create a tranquil atmosphere conducive to restful sleep.

Melatonin for Sleep Regulation

Melatonin, a hormone that regulates the sleep-wake cycle, has been shown to aid in falling asleep faster and improving overall sleep quality. A 2016 study found that melatonin supplementation significantly benefits individuals experiencing insomnia. Taking 1 to 5 mg of melatonin 30 minutes to two hours before bedtime can facilitate an easier transition into sleep.

When To Consult A Doctor

If natural remedies and lifestyle changes fail to improve sleep quality, seeking medical advice may be necessary. Chronic insomnia could be linked to underlying health conditions such as diabetes, thyroid disorders, cardiovascular issues, or respiratory diseases. In such cases, behavioral therapy or medical intervention may be required to address persistent sleep disturbances.

A simple biomarker blood test can now detect dementia in women 25 years before symptoms appear, a JAMA study suggests.

Researchers from the University of California San Diego have found a protein in the blood called plasma phosphorylated tau 217 (p-tau217), a protein linked to the brain changes seen in Alzheimer’s disease.

The researchers found a strong association between higher levels of p-tau217 in the blood and a higher chance of developing both mild cognitive impairment (MCI) and dementia, a key contributer in the developemnt of Alzheimer’s.

Neuroscientist Linda McEvoy, from the Kaiser Permanente Washington Health Research Institute: "Blood-based biomarkers like p-tau217 are especially promising because they are far less invasive and potentially more accessible than brain imaging or spinal fluid tests.

"This is important for accelerating research into the factors that affect risk of dementia and for evaluating strategies that may reduce risk."

The connection between higher p-tau217 and dementia was stronger in women over 70, the researchers also found, and in those carrying the APOE ε4 gene that has been linked to Alzheimer's disease in the past.

What Is Dementia?

Dementia is an umbrella term used to describe a significant decline in mental function that is serious enough to affect everyday life. It commonly impacts memory, thinking, and reasoning skills.

Dementia itself is not a single disease but a collection of symptoms caused by underlying conditions such as Alzheimer’s disease or vascular dementia.

Common signs include memory problems, confusion, difficulty finding words, changes in mood or behaviour and trouble completing familiar tasks.

These symptoms usually worsen over time and are not considered a normal part of ageing. Although there is no cure, treatment options can help manage symptoms, and early diagnosis plays an important role in care planning.

Alzheimer’s Disease: The Leading Cause of Dementia

Alzheimer's disease is one of the most common forms of dementia and mostly affects adults over the age of 65.

About 8.8 million Indians aged 60 and above are estimated to be living with Alzheimer's disease. Over seven million people in the US 65 and older live with the condition and over 100,00 die from it annually.

Alzheimer's disease is believed to be caused by the development of toxic amyloid and beta proteins in the brain, which can accumulate in the brain and damage cells responsible for memory.

Amyloid protein molecules stick together in brain cells, forming clumps called plaques. At the same time, tau proteins twist together in fiber-like strands called tangles. The plaques and tangles block the brain's neurons from sending electrical and chemical signals back and forth.

Over time, this disruption causes permanent damage in the brain that leads to Alzheimer's disease and dementia, causing patients to lose their ability to speak, care for themselves or even respond to the world around them.

While there is no clear cause of Alzheimer's disease, experts believe it can develop due to genetic mutations and lifestyle choices, such as physical inactivity, unhealthy diet and social isolation.

Early symptoms of Alzheimer's disease include forgetting recent events or conversations. Over time, Alzheimer's disease leads to serious memory loss and affects a person's ability to do everyday tasks.

There is no cure for this progressive brain disorder and in advanced stages, loss of brain function can cause dehydration, poor nutrition or infection. These complications can result in death.

Once seen only among the elderly, glaucoma, also known as irreversible blindness, is increasing among younger adults in their 20s and 30s, said experts.

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

Beyond the role of genetics, unhealthy lifestyles with increased screen time and stress are the major reasons for the rise in glaucoma cases in young adults.

"We have seen an increasing incidence of glaucoma among younger adults in their 20s and 30s because of lifestyle habits such as increased screen time and lack of sleep, an increase in diabetes and high blood pressure, and a genetic predisposition," Dr. Mahipal Singh Sachdev, Chairman & Medical Director, Centre For Sight Group of Eye Hospitals, told HealthandMe.

Why Is Treatment Difficult

A major challenge with glaucoma is its lack of symptoms in the initial stages. As a result, the condition is often diagnosed at an advanced stage, where treatment yields the least results.

More than 75 percent of glaucoma cases globally remain undiagnosed.

Although the condition does not directly lead to mortality, glaucoma-led blindness is categorized as a severe form of disability (category VI) out of seven World Health Organization (WHO) classifications on the global burden of diseases.

"Often referred to as a silent thief of sight, glaucoma usually has no warning signs until the damage to the optic nerve has already caused permanent vision loss," Sachdev said.

"Because there are no noticeable symptoms in the early stages of glaucoma, many people have been unaware that they are developing it until it has progressed to a point where there is already significant damage and vision loss; this often translates to blindness," he added.

However, increased awareness of glaucoma and increased frequency of eye examinations have helped reduce the time between the onset of the disease and the diagnosis, the expert said.

Glaucoma: Are Children At Risk?

Although rare, children can be born with congenital or paediatric glaucoma as a result of ocular drainage abnormalities.

Dr Devindra Sood, Senior Consultant — Ophthalmology, Max Multi Speciality Centre, Panchsheel Park, told HealthandMe that glaucoma in children is uncommon.

"Its presentation for diagnosis and treatment is also different from that in adults," Sood said.

The symptoms of pediatric glaucoma include:

• enlargement of the globe,
• excessive lacrimation,
• photophobia,
• corneal cloudiness.

Sood stated that traditionally, large eyes are considered to harbor glaucoma.

These children usually do not respond to medical treatment, and surgical intervention is required.

However, early detection and treatment of congenital glaucoma are vital to reducing the risk of permanent visual impairment, Sachdeva said.

Glaucoma: A Global Health Burden

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

The chronic disease affects an estimated 80 million individuals globally. By the year 2040, it is estimated that there will be 22 million individuals worldwide who are blind from glaucoma.

In India, around 12 million people suffer from glaucoma, and 1.5 million are blind due to it.

When to see a doctor for glaucoma:

• Vision suddenly gets blurry

• Severe eye pain

• Headache

• Nausea

• Vomiting

• Rainbow-colored rings or halos around lights.

A team of researchers in the US has developed a nanoparticle-based technique that could make laser surgeries for kidney stones faster, safer, and potentially reduce the chances of recurrence.

Engineers from the University of Chicago and doctors from Duke University added dark nanoparticles to a common saline solution used in kidney stone laser surgeries. Their method also promised less recurrence of disease.

The research focused on laser lithotripsy, a widely used surgical method in which lasers are used to break kidney or urinary tract stones into tiny fragments that can then be removed by suctioning or pass naturally.

How Nanofluid Boosts Lasery Surgery

Traditionally, surgeons use a small video-guided laser to fragment the stones. However, achieving effective fragmentation often requires higher laser power, which generates additional heat and causes damage to the surrounding tissues.

Thus the new method “is a way to better utilize the laser energy that is already being employed,” said Po-Chun Hsu, assistant professor at the University of Chicago Pritzker School of Molecular Engineering (UChicago PME).

Hsu noted that their nanoparticle-based “nanofluid” also has the potential to enhance the performance of lasers without increasing power levels. This will effectively fragment the stones and remove the dust particles.

The study, published in the journal Advanced Science, describes an innovative saline solution that enhances the performance of existing laser systems without requiring modifications to the equipment.

By adding dark nanoparticles that absorb laser wavelengths, the solution ensures that more of the laser energy is directed at the kidney stone rather than being reflected or dispersed.

“This improves the amount of laser energy that is transmitted to and absorbed by the stones,” said corresponding author Pei Zhong, a professor of engineering at Duke University.

“Nanofluid introduces a new dimension that can influence this complex physical process, independent of the stone composition or the laser being used,” Zhong said.

Kidney Stone Laser Surgery In 10 Minutes

Laboratory tests using artificial kidney stones showed that the nanofluid increased stone ablation efficiency by between 38 and 727 percent in spot treatments and by 26 to 75 percent in scanning treatments.

The researchers also tested the nanoparticle solution on living cells for up to 24 hours and found it to be non-toxic and safe.

In clinical settings, however, exposure would be much shorter. Laser lithotripsy is typically an outpatient procedure lasting about 30 minutes. The researchers believe that improved laser absorption could reduce the procedure time to around 10 minutes.

“If surgeries take too long, waste heat from the laser can accumulate and cause more harm than the stone removal itself,” Hsu said.

Kidney Stones: Symptoms And Prevention

Kidney stones are hard mineral or acid salt deposits formed in the kidneys. It occurs due to concentrated urine, and causes intense, radiating back/side pain, nausea, and blood in urine.

Common causes include

• dehydration,
• diet,
• obesity,
• family history
• metabolic issues

• staying well-hydrated
• reducing sodium levels
• eating fewer oxalate-rich foods
• consuming sufficient calcium-rich foods
• increasing citrus intake.
