If you frequently feel the need to nap during the day, you’re not alone. Many people turn to a quick power nap to recharge and combat tiredness. The quality and duration of sleep are closely tied to both physical and mental well-being. Adults should strive for 7-9 hours of sleep per night, which can become increasingly difficult with age. A new study suggests a link between daytime napping and increased mortality risk factors in older adults and seniors.
For decades, scientists have explored the impact of calorie restriction on overall health. Reducing calorie intake may decrease metabolic rate, potentially slowing the aging process and activating key biological pathways essential for maintaining good health and muscle rejuvenation. Additionally, it may lower the production of free radicals, enhance cellular tolerance to stress, and guard against diseases that can shorten lifespan.
Dementia is a growing global health challenge that takes a significant toll on both individuals and society. With no cure yet available, finding ways to slow its progression or reduce the risk of developing it is critical for supporting healthy aging. Now, new research points to weight training as a potential way to help protect the brain from dementia.
A recent study suggests that phosphate additives, commonly used to preserve and enhance the flavor of processed packaged foods, may increase blood pressure. This is due to causing the protein FGF23 to build up in the blood and infiltrate key brain areas, such as the brain stem, that regulate blood pressure.
Adequate sleep is crucial for overall health. Insufficient sleep often leads to heightened cognitive deficits. A recent study reveals that older adults with insomnia face a higher risk of memory decline and long-term cognitive impairments, which can lead to dementia. The study utilized a large dataset and primarily focused on sleep disorders.
PFAS, or "forever chemicals," are widespread in the environment and can accumulate in our bodies. These synthetic chemicals infiltrate our food, water, household products, and even our bodies. They resist breakdown and persist in the environment and the human body, earning the label "forever chemicals". Specific strains of human gut bacteria can effectively absorb these "forever chemicals", trapping them within their cells. The full impact of PFAS on health remains unclear, but studies have connected these chemicals to cancer, heart disease, reduced fertility, and other adverse effects.
Scientists are increasingly focusing on nutrients that go beyond basic bodily functions to promote healthy aging. Recent research reveals that vitamin D supplements may counteract cellular aging signs.
A recent report from the CDC reveals a troubling increase in prediabetes among U.S. adolescents, raising alarms about the health of American youth. In 2023, nearly one in three U.S. teens aged 12 to 17 was diagnosed with prediabetes. This is a warning sign for diabetes, a condition where blood sugar levels become excessively high. It is marked by mildly elevated blood sugar, signaling a risk of progressing to Type 2 diabetes.
A new brain imaging study indicates that ultra-processed food consumption increases hunger and overeating resulting in weight gain. This is concerning and sparks worries that these widespread products may fundamentally reshape our eating patterns. This may be a result of altered brain structure by changing neural pathways.
Vitamin C, also called ascorbic acid, is vital for the body, acting as a strong antioxidant and helping with important chemical reactions. A recent study reveals that Vitamin C enhances skin cell growth and repair by stimulating key genes that promote cell regeneration and strengthening of the skin without altering the DNA sequence.
Recent research indicates that smoking marijuana or consuming THC gummies can adversely affect vascular health. Even healthy individuals who use cannabis may have a higher risk of developing heart disease.
Stem cells impact the immune system in various ways, influencing tissue repair, modulating immune responses, and affecting the progression of certain diseases, both directly and indirectly. Blood is composed of various cell types that evolve from a common precursor, the blood stem cell. A research team has recently explored the developmental pathways of human blood cells and have found surface proteins that help them inhibit the activation of inflammatory and immune responses within the body.
