Many people consistently miss out on enough sleep, prompting searching for better sleep solutions. A person's diet and eating habits significantly affect sleep duration and quality. A recent study revealed that individuals consuming more ultra-processed foods had a 53% greater risk of insomnia than those who ate less of these foods.

About one-third of U.S. adults now have tattoos, a significant rise over the past two decades. People get tattoos for various reasons, including personal identity, commemorating memories, or embracing self-transformation. A recent study indicates a possible connection between tattoos and a higher risk of developing malignant lymphoma, a type of blood cancer impacting the lymphatic system.

New research reveals that using smartphones or tablets an hour after getting into bed increases insomnia risk by 59%. This insight, drawn from a major study on university students' screen habits and sleep, underscores how late-night devices may significantly disrupt a person’s sleeping habits.

Water makes up over half of the adult human body weight and is essential for key functions like waste elimination and joint lubrication. Every cell, organ, and tissue in the body depends on water to operate. Your body continuously loses water daily, so you need to replenish it through foods and drinks to avoid dehydration. Typically, a person can survive only a few days without water.

Swimming is an excellent form of exercise, but the chemicals used to keep pools germ-free can pose health to various parts of the body. A recent study highlights that disinfectants commonly used in swimming pools, such as chlorine and bromine, produce disinfection by-products when they interact with organic materials in the water. These by-products, called chloramines, form when chlorine reacts with substances like sweat and urine. Chloramines can irritate the eyes, skin, and respiratory passages, posing health risks to swimmers.

A recent study indicates that eating mostly plant-based foods, limiting ultra-processed products, and consuming minimal amounts of animal-based foods may improve our odds of reaching age 70 without chronic illnesses.

Bone regeneration is a key focus in regenerative medicine, as strong bones are vital for movement and overall health. Stem cells are essential in this process, transforming into bone-forming cells and releasing growth factors that speed up healing. Recent research has revealed new understanding into how stem cells maintain and repair bones, and how aging and poor healing conditions disrupt this process.

Researchers have found that earwax is a rich source of health information. Its chemical makeup is now being studied, which could potentially uncover new methods for diagnosing diseases such as Alzheimer’s, diabetes and cancer.

As a person ages, the brain gradually shrinks, losing about 5% of its volume per decade after age 40, impacting its functionality. In a pioneering study, neuroscientists investigated how regular aerobic exercise affects the hippocampus, the brain region responsible for memory. 

Household dust is an intricate blend of organic material, microbes, and hazardous chemicals. These include biological contaminants such as mold, bacteria, mildew, and dust mites, alongside toxic substances such as mercury, lead, and flame retardants, posing potential health risks. Driven by the harmful impact of cleaners, medications, and environmental pollutants, dust often accumulates over months or years, creating a potent microbial mix.

Centenarians are exceptional in that they avoided the diseases, stresses, and misfortunes that claimed the lives of others in their generation. To truly understand how to extend life, it's more useful to study the reasons why most people don't reach 100, and address those factors, rather than focusing on those who may have simply been fortunate in terms of lifestyle or genetics.

Lung cancer has not typically been considered linked to diet. Yet, recent research has revealed an unexpected factor contributing to lung cancer risk. The mix of sugar and fat in our diets. A diet high in sugar and fat could cause glycogen, a form of stored sugar, to build up in lung tissues. Researchers believe this buildup could potentially set the stage for cancer development.
