Fitness

It’s well-established that exercise improves health. Regular physical activity not only fortifies muscles but also enhances blood vessels, bones, and immune system. But might it also promote the growth of nerve cells? Recent research indicates that exercise can enhance neuron development not just through biochemical pathways but also through the mechanical actions of muscle contractions.

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.

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.

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. 

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.

According to a recent study, 20 years of a sedentary lifestyle is linked to two times the risk of premature death when compared to being physically active. The HUNT study’s findings suggest that in order to get maximum health benefits from physical activity to protect against premature cardiovascular and all cause death, a person needs to be continually physically active.
