Prenatal pesticide exposure linked to changes in teen’s brain activity

A new study led by University of California, Berkeley, researchers is one of the first to use advanced brain imaging to reveal how exposure to these chemicals in the womb changes brain activity

Prenatal pesticide exposure linked to changes in teen’s brain activityOrganophosphates are among the most commonly used classes of pesticides in the United States, despite mounting evidence linking prenatal exposure to the chemicals to poorer cognition and behaviour problems in children. The study, which appeared this week in the journal Proceedings of the National Academy of Sciences, used functional near-infrared imaging (fNIRS) to monitor blood […]

Screen time ‘not to blame’ for teenagers mental health problems, says study

A new study, published in the journal Clinical Psychological Science, suggests that the time adolescents are spending on their phones and online is not that bad

Screen time ‘not to blame’ for teenagers mental health problems, says studyThe study tracked young adolescents on their smartphones to test whether more time spent using digital technology was linked to worse mental health outcomes. The researchers – Candice Odgers, professor of psychological science at the University of California, Irvine; Michaeline Jensen, assistant professor of psychology at the University of North Carolina at Greensboro; Madeleine George, […]

Joining a choir may help elders enjoy life, suggest researchers

Singing in a community choir may provide some psychological benefit to seniors, a small study suggest. Researchers had primarily hoped to see choir participation yield improvements in elderly people’s thinking skills and physical fitness, but that didn’t happen. They did, however, see improvements in loneliness and interest in life among seniors in the singing groups

Joining a choir may help elders enjoy life, suggest researchersThe study was conducted at 12 senior centers serving racially and ethnically diverse communities in and around San Francisco. Half of the centers were randomly selected for the choir program; the others served as a control group. Ultimately, 208 people participated in the choirs and 182 in the control group. None of them had been […]

Time-restricted eating may prevent tumour growth, suggests study

A new study suggests that rather than changing what they eat to prevent tumour growth, a person may benefit from simply timing their meals differently

Time-restricted eating may prevent tumour growth, suggests studyResearchers have already identified obesity as a risk factor for cancer, so some doctors recommend reducing caloric intake to help prevent tumours. However, a new study now finds that prevention may be less about how many calories you consume and more about when you eat your meals. This study states that time-restricted eating can prevent tumour […]

Could beetroot fight salt-induced high blood pressure?

Adding tiny amounts of beetroot or dietary nitrate to salty food products might help prevent high blood pressure, according to a preliminary study of rats

Could beetroot fight salt-induced high blood pressure?While findings in animals may not translate to humans, researchers of the new study, released Thursday in the American Heart Association journal Hypertension, hope to find a new tool to help battle the epidemic of high-salt diets, a major risk factor for hypertension.  Findings of the new study state beetroot fight salt-induced high blood pressure. […]

Teens who seek solitude may know what’s best for them

Teens who choose to spend time alone may know what’s best for them, according to new research that suggests solitude isn’t a red flag for isolation or depression

Teens who seek solitude may know what’s best for them  The key factor is choice, say researchers at the University of California, Santa Cruz, and Wilmington College: When solitude is imposed on adolescents and young adults, whether as punishment or as a result of social anxiety, it can be problematic. But chosen solitude contributes to personal growth and self-acceptance, they found. “Solitude has gotten […]

Study finds: Exercise can shift human body clock depending on time when people work out

Exercise can shift the human body clock, with the direction and amount of this effect depending on the time of day or night in which people exercise

Study finds: Exercise can shift human body clock depending on time when people work outThat’s according to new research in published in The Journal of Physiology. These findings suggest exercise could counter the effects of jet lag, shift work, and other disruptions to the body’s internal clock (e.g. military deployments) helping individuals adjust to shifted schedules. The circadian ‘body’ clock is the 24 hour cycle that regulates many physiological […]

#WorldCancerDay: Missed cancer screenings tied to earlier death from other causes

Adults who skip recommended cancer screenings may be more likely than those who don’t skip them to die prematurely from causes unrelated to malignancies,  suggests an American study 

#WorldCancerDay: Missed cancer screenings tied to earlier death from other causesResearchers think skipping screenings may be a marker for more generally neglecting one’s own health. “It was not a direct effect of missing the cancer screening that led to the increased mortality in the non-compliers,” said study co-author Dr Paul Pinsky of the National Cancer Institute in Bethesda, Maryland. “Rather, we believe that non-compliance with […]

Scientists reveal why sleep is the best painkiller that nature can provide

A lack of sleep impairs the brain's natural mechanisms for relieving pain, finds the new study, which draws attention to potential links between the public health crises of sleep deprivation, chronic pain, and prescription opioid addiction

Scientists reveal why sleep is the best painkiller that nature can provideNew research, published in the Journal of Neuroscience, finds that sleep deprivation increases sensitivity to pain by numbing the brain’s painkilling response. The effects of sleep deprivation on the brain are numerous, from inducing an inebriation-like state of cognitive impairment to hindering our ability to learn and form new memories. New research highlights another neurological […]

Fasting might help prevent age-related diseases, suggest US study

Fasting may protect you against age-related diseases and improve your overall health, reveal researchers. While food is known to influence clocks in peripheral tissues, it was unclear, until now, how the lack of food influences clock function and ultimately affects the body

Fasting might help prevent age-related diseases, suggest US studyFasting may not be just a mere religious or lifestyle practice. It might actually serve to protect you against age-related diseases and improve your overall health, reveal researchers. This study opens new avenues of investigation that could ultimately lead to the development of nutritional strategies to improve health in humans Each and every one of […]
