Early-Life Exposure to Dogs Linked to Decreased Schizophrenia Risk

Owning a pet has been associated with many health benefits, ranging from decreased blood pressure and cholesterol levels to increased life expectancy. Pet dogs specifically provide opportunities for increased physical activity, socialization, and time spent outdoors while also improving emotional well-being by providing their owners with companionship. As a result, pet ownership is on the rise, according to data from the American Pet Products Association’s National Pet Owners Survey. Per current estimates, 67% of households in the United States own at least one pet – which equals approximately 85 million homes across the country.

The full extent of the health benefits – and risks – of pet ownership is yet unknown, however, the latest research reveals that there may be positive neurologic implications of owning a dog. Published online in the journal PLOS One, a recent study from Johns Hopkins Medicine implicates that exposure to dogs at an early age may have psychiatric health benefitsincluding the lessening of the likelihood of schizophrenia development in adulthood.

The Benefits and Potential Risks of Calcium Supplements

A sufficient amount of calcium is critical for overall health, keeping the bones, organs, and skeletal muscles functioning properly. For decades, calcium intake has been thought to be helpful in the prevention and treatment of osteoporosis — one of the leading causes of disability in the elderly population. In order to promote bone health in aging individuals, a daily dietary calcium intake of 1,000-1,2000 mg is recommended for both women and men. However, this can be difficult to achieve through nutritional choices alone, resulting in the wide use of calcium supplements to boost overall intake.

A Look into Senolytic Therapies for Longevity

With a focus on extending and improving the human lifespan, the medical community continues to explore potential avenues in longevity. One such development has directed increased attention to the practice of senolytics – or, the process of flushing senescent cells from the body to discard harmful proteins. Senescent cells are malfunctioning, aged cells which can trigger inflammation and dysfunction, developed in response to disease, injury, or cancerous formations. 

These cells can remain in the body, contributing to the development of many diseases and features of aging, such as heart disease, dementia, osteoporosis, and lung disease. Removing senescent cells from mice was found to alleviate insulin resistance, cell dysfunction, and ameliorate other complications in cases of kidney failure and disease.
