The herb ashwagandha is one of the most important herbs in Ayurveda, a form of natural Indian folk medicine. It has been used for more than 3,000 years to boost energy and ease stress. And modern research is discovering that this ancient herb can treat a host of modern illnesses.
Ashwagandha’s Latin name, somnifera, means sleep-inducing, and a new Japanese study found that the herb truly does improve sleep.
Researchers at the University of Tsukumba used a neurological test (EEG) to record activity in the brains of mice that were given ashwagandha. They found that an extract of ashwagandha leaf, which was rich in the component triethylene glycol (TEG), significantly increased non-rapid eye movement (NREM) sleep.
The sleep induced by TEG was similar to normal sleep, and researchers believe that ashwagandha could revolutionize the natural plant-based therapies for insomnia and sleep-related disorders, producing natural sleep without side effects.
An earlier study published in Alternative Medicine Review found that volunteers reported an improvement of 66.9 percent in sleep quality. Participants also reported a 42 percent improvement in emotional health and a 45.8 percent improvement in their social life and activities.
In addition to inducing sleep, ashwagandha also provides the following health benefits:
Inhibits Alzheimer’s. Herbal doctors have been using ashwagandha for centuries as a remedy for memory loss, and scientists at the U.K.’s Newcastle University may have discovered why it is effective. They found that ashwagandha inhibits the formation of the beta-amyloid plaques that accumulate in the brains of Alzheimer’s victims.
The study, which was published in Phytotherapy Research examined the effects of water-based ashwagandha extracts on beta-amyloid peptides in test tubes, and found that the herb prevented them from forming clumps, a main characteristic of Alzheimer’s.
In a study conducted at India’s National Brain Research Center on mice with Alzheimer’s, their brain function returned to normal after 30 days of treatment, and the amyloid plaques in their brains decreased.
Another study published in the Chemical Pharmacy Bulletin found that ashwagandha inhibits acetylcholinesterase, the enzyme that breaks down the neurotransmitter acetylcholine. (Neurotransmitters are chemicals made by nerve cells that send signals to other cells.) Current drugs prescribed to treat Alzheimer’s disease target this mechanism.
Reduces stress. A 2012 Indian study of people with chronic stress found that taking ashwagandha supplements for two months lowered stress by 44 percent and eased depression and anxiety by 72 percent. Tests showed that blood levels of cortisol — the stress hormone — were reduced substantially.
The study, which was published in the Indian Journal of Psychological Medicine concluded that the herb was safe and “effectively improves an individual’s resistance towards stress and thereby improves self-assessed quality of life.”
Aids weight loss. A 2016 double-blind, randomized, placebo-controlled study of stressed volunteers found that ashwagandha reduced stress and food cravings and also helped subjects lose weight. The eight-week study was published in the Journal of Evidence-Based Complementary & Alternative Medicine.
Fights cancer. Studies show that ashwagandha slows the growth of many types of cancer cells. It works in multiple ways to prevent or slow cancer. In a study published in PLoS One, mice with ovarian cancer that were treated with ashwagandha either alone or with an anti-cancer pharmaceutical reduced tumor growth by 70 to 80 percent and also prevented the cancer from spreading to other parts of the body.
A 2011 study published in Biochemical Pharmacology found that ashwagandha was effective against four types of cancer — lung, colon, breast, and central nervous system (CNS) lymphoma — and a steroidal component of the herb called withaferin A showed a stronger effect on breast and colon cancer cell lines than the chemotherapy drug Adriamycin.
Other studies have found that ashwagandha also protects normal cells against cancer, shelters normal cells from being harmed by chemotherapy, and stops the growth of new blood vessels that help cancer grow and spread.
New US research has found evidence that including omega-3 and omega-6 fatty acids in the diet can help to promote healthy brain aging.
Led by Marta Zamroziewicz from the University of Illinois, the research team carried out two studies which looked at omega-3 and omega-6 polyunsaturated fatty acids in the blood of adults ages 65 to 75, and a possible relationship between these fatty acids and the participants’ brain structure and cognitive performance.
As the brain is made up of interconnected parts which age at their own pace, some brain structures and their function deteriorate earlier than others.
The first study, published in the journal Nutritional Neuroscience, focused on the frontoparietal network. This part of the brain plays an important role in fluid intelligence, which is the ability to solve new problems that have not been encountered before.
The team looked for a link between the size of this network, performance on tests of fluid intelligence, and the levels of several omega-3 fatty acids in the blood.
The results showed those with higher blood levels of three omega-3 fatty acids — ALA, stearidonic acid and ecosatrienoic acid — also tended to have a larger frontoparietal cortex, which predicted the subjects’ performance on tests of fluid intelligence.
The second study, published in the journal Aging & Disease, looked at the white matter structure of the fornix, which is found at the center of the brain and is important for memory. Previous research has also found that the fornix is one of the first brain regions to be affected in Alzheimer’s disease.
In the new research the team also found that the size of the fornix was associated with a balanced level of omega-3 and omega-6 fatty acids in the blood, and that a larger fornix was linked with better memory in older adults.
Although the team noted that further research is needed to test their hypothesis, Zamroziewicz added that “These findings have important implications for the Western diet, which tends to be misbalanced with high amounts of omega-6 fatty acids and low amounts of omega-3 fatty acids.”
“A lot of research tells us that people need to be eating fish and fish oil to get neuroprotective effects from these particular fats, but this new finding suggests that even the fats that we get from nuts, seeds and oils can also make a difference in the brain,” she added.
For men experiencing emotional distress like depression, anxiety or thoughts of suicide, having high cardiorespiratory fitness may cut the risk of death in half compared to those in poor condition, researchers say.
“The prevalence of mental health issues is growing in the U.S. and globally,” said lead study author Mei Sui of the University of South Carolina in Columbia. “People are facing many stressors in their daily lives linked to depression, anxiety and other mental disorders.
“Medication to treat these mental problems is not only expensive but also comes with significant side effects such as weight gain,” she told Reuters Health. “Identifying modifiable factors that are beneficial to those with emotional distress has important clinical and public health applications.”
Mental health conditions cost the U.S. about $2.5 trillion in 2010 and are projected to cost the country $6 trillion by 2030, the authors write in Mayo Clinic Proceedings.
To see how cardiovascular fitness might affect healthcare costs and outcomes for people with mental health disorders, Sui and colleagues analyzed data from the Aerobics Center Longitudinal Study at the Cooper Clinic in Dallas, Texas, which conducted preventive health exams on more than 43,000 men between 1987 and 2002.
The researchers focused on 5,240 participants who reported a history of emotional distress, including 2,229 who reported more than one emotional distress condition. To measure cardiorespiratory fitness, participants ran on a treadmill until they were exhausted.
Among men who experienced emotional distress, 46 percent reported depression, 58 percent had anxiety, 51 percent had a history of mental counseling, and 8 percent reported ever having thoughts of suicide.
By the end of the follow up period, there were 128 deaths from any cause.
The researchers found that men with the lowest cardiovascular fitness tended to have higher weight, blood pressure, cholesterol and blood sugar levels and were more likely to smoke and to be sedentary.
In addition, men who reported more than one type of emotional distress were more common in the low-fitness group.
Compared to the lowest-fitness group, men with moderate cardiovascular fitness were 46 percent less likely to die of any cause during the study, and those in the high fitness group were 53 percent less likely to die.
“This significant strong inverse association between high levels of fitness and longevity in men with emotional distress is particularly interesting,” Sui said. “Clearly lifestyle behavior interventions to increase fitness levels could help those with emotional distress.”
Even moderate levels of fitness were associated with a 46 percent lower risk of dying, she noted. This moderate level of fitness means 30 minutes per day of activity such as swimming, jogging or biking, and is the current level recommended under American sports medicine guidelines.
The study mostly included non-Hispanic whites, and Sui would like to see more research about fitness in women and minority groups.
“This was the missing piece of the puzzle. We know now that assessing fitness and treating it should be at the center of mental health care,” said Davy Vancampfort of the University of Leuven Psychiatric Center in Belgium. He wasn’t involved in the current study but recently published an analysis that found people with severe mental illness are at heightened risk for heart disease
“This adds to our call to include assessment of physical activity and treatment to the standard mental health care package,” he told Reuters Health by email. “Mental health care settings and primary care settings should work closely together on this.”
Future research could also look at older populations, follow people for a longer period of time and account for medication such as psychotropic prescriptions in particular, said Brandon Stubbs of King’s College London in the UK.
“One in four of us will at some point experience a common mental illness in our lives,” Stubbs, who wasn’t involved in the study, told Reuters Health by email. “We can no longer view mental health and physical health separately given that they are so inextricably linked.”
A growing number of U.S. children may develop vision problems before they reach kindergarten, according to a study that suggests eye screenings will become increasingly important for the preschool set.
For the study, researchers analyzed data from U.S. census records and from eye exams on about 12,000 kids under 6 years old. Nationwide, researchers estimated that more than 174,000 kids from 3 to 5 years old had vision impairment as of 2015 and projected that their ranks will swell by 26 percent to more than 220,000 by 2060.
Most of these kids have what’s known as refractive errors, or difficulties focusing on things either up close or far away, that can be often be corrected with glasses. This means parents should take kids for at least one comprehensive eye exam by age 3 and watch for signs of vision issues, said lead study author Dr. Rohit Varma, director of the Roski Eye Institute and dean at the Keck School of Medicine at the University of Southern California in Los Angeles.
“Parents should watch out for signs such as sitting close to the TV or holding a book too close, squinting, tilting their head, frequently rubbing their eyes, short attention span for the child’s age, turning of an eye in or out, sensitivity to light, difficulty with eye-hand-body coordination when playing ball or bike riding, or avoiding coloring activities, puzzles and other detailed activities,” Varma said by email.
“If children display such symptoms or behaviors then they should certainly get an eye examination,” Varma added.
Hispanic children were most likely to have vision problems, researchers report in JAMA Ophthalmology. As of 2015, Hispanic kids accounted for 38 percent of vision impairment cases, and researchers estimated this proportion would climb to 44 percent by 2060 aided by higher birth rates in this population relative to other racial and ethnic groups.
Based on changing demographics across the country, the second most-affected group is expected to shift from non-Hispanic white kids, who represented 26 percent of cases in 2015, dropping to 16.5 percent in 2060, to African American kids, representing 25 percent of cases in 2015 and 22 percent in 2060, according to the researchers.
The states projected to have the most children with vision impairment by 2060 are California, Texas and Florida, all of which have large Hispanic populations.
Overall, the types of vision problems found in kids are projected to remain little changed by 2060, however.
Refractive errors will make up about 70 percent of cases by 2060, followed by amblyopia, or lazy eye, accounting for 24 percent. About 6 percent of cases will result from eye disease.
One limitation of the study is the reliance on census records with self-reported data on race and ethnicity, the authors note. Researchers also assumed the prevalence of impaired vision within different racial and ethnic groups would not change over time, so increases and decreases are based just on population changes.
Still, the findings should serve as a reminder to parents not to wait to get children’s eyes checked until kids complain about their vision, said Dr. Janet Leasher of the Nova Southeastern University College of Optometry in Fort Lauderdale, Florida.
“Many children don’t know that the way they see may not be normal, and the only way to find out is to have them assessed by a qualified eye care professional,” Leasher, who wasn’t involved in the study, said by email. “There are pediatric ophthalmologists and optometrists who specialize in children’s vision, but any eye doctor can conduct the tests necessary to determine if there is a problem.”
As warm weather approaches, U.S. health officials are warning that outbreaks of diarrhea caused by swallowing swimming pool water containing parasites have doubled in the past few years.
The infections occur when swimmers ingest water contaminated by diarrhea from a person infected by Cryptosporidium or Crypto, a parasite that is notoriously difficult to kill.
Crypto caused at least 32 outbreaks in swimming pools or water parks in 2016, compared with 16 in 2014, according to a report published in the U.S. Centers for Disease Control and Prevention’s weekly report on death and disease.
Arizona last year reported that 352 people became sick with Cryptosporidiosis from July through October, compared with no more than 62 cases per year from 2011 to 2015. Ohio reported 1,940 infections in 2016, compared with no more than 571 in any one year from 2012 to 2015.
The CDC said it was not clear if there are actually more outbreaks, or if states are doing a better job of reporting them since it introduced a new DNA-based tracking tool in 2010.
Crypto is the most common cause of diarrhea outbreaks linked with swimming pools or water parks because it can survive up to 10 days in chlorinated water. It only takes a mouthful of contaminated water to make a healthy person sick for up to three weeks. Infections can cause watery diarrhea, stomach cramps, nausea or vomiting, and can lead to dehydration.
To kill the parasite, the CDC recommends closing pools and treating the water with high levels of chlorine, called hyperchlorination.
The CDC advises parents not to let children swim if they have diarrhea. People who are infected with Crypto should wait two weeks after the diarrhea stops before swimming. And to keep from getting sick, the CDC advises swimmers not to swallow pool water.
Women in their early 40s with the highest intake of vitamin D and calcium from food sources may have a lower than average risk of starting menopause before age 45, a recent study suggests.
Taking vitamin D or calcium in supplement form had no benefit in the large study of U.S. nurses, the study team writes in American Journal of Clinical Nutrition, and there may be other substances in dairy foods that also contribute to their apparent protective effect.
“Early menopause can have substantial health impacts for women. It increases their risk of cardiovascular disease and early cognitive decline and osteoporosis,” lead author Alexandra Purdue-Smithe told Reuters Health.
In addition, as women are delaying having kids into their later reproductive years, having early menopause can have a substantial impact on their ability to conceive as they wish, which can have psychological and financial consequences, said Purdue-Smithe, an epidemiologist with the School of Public Health and Health Sciences at the University of Massachusetts Amherst.
“Given that (early menopause) affects roughly 10 percent of women in the U.S. and other Western populations, it felt like a worthwhile problem to start investigating and seeing if there are any potentially modifiable risk factors for it,” she said.
Menopause, when a woman stops menstruating and her levels of hormones like estrogen decline, typically happens between the ages of 45 and 55. Menopause before age 45 is considered “early.”
Vitamin D may be involved in some of the hormonal mechanisms of early menopause, but little is known about how dietary vitamin D and calcium affect the risk, Purdue-Smithe and her colleagues write.
They analyzed data from the Nurses’ Health Study II, a long-term study of more than 100,000 U.S. registered nurses who were 25 to 42 years old in 1989 when they began answering health questionnaires every two years.
The questionnaires were designed to assess the nurses’ lifestyles, behaviors and overall health. Questions about diet were asked five times over 20 years. Researchers followed the participants until 2011, by which time 2,041 women experienced early menopause.
“The women who consumed the most vitamin D from food sources had a 17 percent lower risk of having early menopause as compared to women who consumed the least,” Purdue-Smithe said. The researchers found this association only with dairy sources of vitamin D, like milk, not with non-dairy sources like oily fish.
Women who consumed the most calcium from food sources were also about 13 percent less likely to experience early menopause compared to women who consumed the least calcium, and once again, only dairy foods seemed to provide a benefit.
“Our next direction is to look at actual individual dairy foods and see if there’s something else going on with dairy itself,” Purdue-Smithe said.
The study team also found that taking high doses of calcium in supplement form was associated with a higher risk of early menopause. But the researchers speculate that these women might have been diagnosed with osteoporosis or other conditions that are also risk factors for early menopause.
“Most of what is known about the relationship between calcium and Vitamin D and women’s issues is related to bone health,” said Sandra Arevalo, a dietitian and director of the Nutrition Services and Community Outreach for Community Pediatrics at Montefiore Medical Center in New York.
Lack of Vitamin D and calcium in a woman’s diet, mainly as age progresses, increases her risk of low bone mineral density, osteoporosis and bone fractures, said Arevalo, who wasn’t involved in the study.
The top 10 food sources of calcium are low-fat yogurt, low-fat cheese, sardines, calcium-fortified soy milk, calcium-fortified orange juice, salmon, calcium fortified ready-to-eat cereal, turnips, kale and bok choi, she noted in an email.
The top 10 sources of Vitamin D are cod liver oil, swordfish, salmon, tuna fish, vitamin D fortified orange juice, low-fat vitamin D-fortified milk, yogurt, fortified margarine, sardines and liver, Arevalo said.
Many Americans are overweight or obese and find low back pain is a debilitating problem. Studies have shown that losing weight might have an important effect on controlling low back pain. Weight loss programs can be very helpful for patients that are overweight or obese and who need to relieve their back pain that is low.
However, there are numerous weight loss programs to select from, plus they have their differences. Some are commercialized, others managed with a doctor. Nutritional supplements are endorsed by some plans; drug is prescribed by others. Some are insured by insurance companies; many aren’t.
With each one of these aspects to consider, it�s significant to do a little research to discover the proper weight loss program before signing up and spending any cash. Some weight loss programs might not follow the very best practices recommended by doctors, and it might be hard to tell just by looking at their respective websites.
Health and Wellness Details
A recent study looked at 191 different weight-loss programs in the Maryland�Washington, DC�Virginia region. The overwhelming bulk of programs did not offer enough important info on their websites.
The kind of diet, the amount of exercise, types of behavioral treatments, use of drugs�these are all vital details that were missing online. Many sites aren’t designed to provide details of a program, but alternatively to offer contact information for prospective clients.
Finding the Proper Weight Loss Program
A comprehensive lifestyle program should feature:
A somewhat- caloric meal plan that is reduced
A regimen for increased physical action
A behavioral therapy strategy
These are three vital aspects to a highly effective weight loss plan, as recommended by the American Heart Association, American College of Cardiology, as well as the Obesity Society (AHA/ACC/OBS). FDA-approved medications to help treat obesity are accessible, but have to be prescribed by an accredited physician.
Some programs may include weight loss supplements ; again, information that might not be mentioned on an internet site. Patients ought to be mindful with products not accepted by the FDA. Some materials may be ineffective or possibly harmful, which explains the reason why it is essential to consult a physician before taking something to lose weight.
Seek Professional Advice
Many weight loss programs are commercialized products or services that don’t meet professional standards. Based on Dr. J. Michael Gonzalez-Campoy, MD, PhD, FACE, a specialist in obesity medicine, patients should first seek guidance from health care professionals who are trained to treat obesity and overweight.
�With the epidemic of overweight and obesity in this country, two-thirds of Americans will seek help managing their weight. The point is well taken that there is a lot of commercialism�selling products with a promise of unrealistic accomplishments. It’s best for every patient to address weight control with their personal health care professional first. � Speaking into a licensed pro is a course that is more efficient and far safer. Patients can locate obesity medicine doctors through the web site of The American Board of Obesity Medicine (ABOM).
Physical Activity With Low Back Pain
Many patients might think it is challenging to be active with low back pain. Nonetheless, inactivity can lead to weak and back muscles that are stiff, and core strength is required to assist support the spine. Walking or working out in a pool (aquatic treatment) is low-impact motion which may be a great choice to help reduce weight and strengthen muscles.
Patients with obesity are more inclined to have weak muscles in their lower back, making it tough to walk on a treadmill or measure mill. A good approach to remaining active with low back pain would be to talk with a specialist�such as physical therapist, physician assistant, or a primary care doctor. It could be wise to procure a precise analysis if pain worsens, and/ although obesity or overweight can cause/contribute to pain in the low back or is accompanied by numbness weakness or tingling sensations.
Regular Exercise is Beneficial
Regular exercise can enable you to prevent exacerbating low back pain during physical action that is prolonged or intense. Over time, routine exercise can increase flexibility, strength and endurance.

Additional Topics: Weight Loss Eases Back Pain
Back pain and symptoms of sciatica can affect a majority of the population throughout their lifetime. Research studies have demonstrated that people who are overweight or obese experience more back complications than people with a healthy weight. A proper nutrition along with regular physical fitness can help with weight loss as well as help maintain a healthy weight to eliminate symptoms of back pain and sciatica. Chiropractic care is also another natural form of treatment which treats back pain and sciatica utilizing manual spinal adjustments and manipulations.
