Body art is more popular than ever, with roughly one-third of people in the U.S. having at least one tattoo. However, tattoo inks often contain harmful chemicals, including carcinogenic pigments and metals. A recent study found that people with tattoos are 21% more likely to develop malignant lymphoma. Researchers conducted a case-control study among roughly 1,400 people diagnosed with malignant lymphoma ("cases") in people aged 20 to 60 over 10 years. They matched the cases with age- and sex-matched people without cancer ("controls") from the general population. Then, they gathered informati... cancer immune system
Read morePhysical exertion and strong emotions activate the body's stress response, triggering the release of hormones that restrict blood flow to the body's tissues, including the heart. A 2016 study found that these stressors increase the risk of myocardial infarction (heart attack). Researchers conducted a case-control study involving more than 12,000 cases of acute MI among people living in 52 countries. They asked the participants about their physical activities and emotional state in the hours before the onset of symptoms. They estimated the odds of acute MI within one hour of triggers. They fou... exercise heart disease mental health
Read moreCardiorespiratory fitness is a measure of the body's aerobic capacity – the ability to deliver oxygen to skeletal muscles – during sustained physical activity. A 2009 meta-analysis found that people with low cardiorespiratory fitness were 70 percent more likely to die prematurely and 56 percent more likely to experience a heart or cardiovascular disease-related event. Researchers evaluated data from 33 studies examining connections between cardiorespiratory fitness and the risk of premature death from all causes (more than 102,000 participants) and combined heart disease and cardiovascular dis... exercise mortality cardiovascular
Read more[toc position='left'] Introduction Omega-3 fatty acids are polyunsaturated fats that play critical roles in human health, participating in a wide range of biochemical pathways and processes and modulating the expression of genes throughout the lifespan. Omega-3 fatty acids include plant-derived alpha-linolenic acid (ALA) and marine-derived eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), among others. A growing body of evidence indicates that omega-3 fatty acids may prevent or ameliorate symptoms associated with chronic health conditions such as cardiovascular disease,[ref doi='10.3... cancer depression mortality omega-3 nutrition brain diet aging immune system mental health development intelligence

Watch nowCOVID-19 primarily manifests as a respiratory illness, but cardiovascular, gastrointestinal, and neurological symptoms have been reported in some cases. Although most of these symptoms are acute and resolve within a few weeks, many people experience long-term complications of the illness, a phenomenon referred to as "post-COVID-19 syndrome (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7491255/_"). A recent report describes the long-term neurological effects of COVID-19. Mounting evidence indicates that COVID-19 affects the neurological system. A previous report found that the range of acute ne... brain covid-19
Read more[toc position='left'] Brain-derived neurotrophic factor, or BDNF, is a growth factor relevant to aging, brain function, behavior, metabolism, energy expenditure, and satiety. BDNF serves as a cell signaling protein, plays vital roles in numerous signaling pathways associated with a variety of disorders ranging from depression, (https://www.foundmyfitness.com/topics/depression) schizophrenia, and addiction to obesity and diabetes, and may serve as a hormone. It is perhaps best known for its influence on the formation, growth, survival, and development of neurons and for its role in mediating th... exercise omega-3 meditation brain alzheimer's parkinson's fasting memory interesting

Read more[toc position='left'] Background Vitamin C, also known as ascorbic acid, is an essential nutrient, widely recognized for its antioxidant properties. These properties arise from its potent redox potential due to its capacity to donate electrons to oxidized molecules. Even in small quantities vitamin C can protect critical molecules in the body such as proteins, lipids, carbohydrates, and nucleic acids (DNA and RNA) from damage by reactive oxygen species, which are generated during normal metabolism, by active immune cells, and through exposure to toxins and pollutants (e.g., certain chemotherap... cancer nutrition exercise interesting

Variations of its use are seen today in the banyas of Russia, the sweat lodges of the American Indians, and, most famously, the saunas of Finland. Sauna use, sometimes referred to as "sauna bathing," is characterized by short-term passive exposure to extreme heat. This exposure elicits mild hyperthermia – an increase in the body's core temperature – that induces a thermoregulatory response involving neu... exercise inflammation sauna aging performance depression bisphenol a heat stress interesting alzheimer's
