Every summer, wildfires worsen air quality in many regions of Canada. At the same time, many people do not realize that the danger exists not only near the fire itself. Smoke can be carried by air currents for hundreds and even thousands of kilometres, so air quality can deteriorate significantly in places where there is no visible fire nearby at all.
Leafy salads and other fresh leafy greens have traditionally been considered an important part of a healthy diet. They contain dietary fiber, natural folates (including folinic acid), chlorophyll, vitamin K, vitamin C, carotenoids, polyphenols, and various minerals. At the same time, most types of leafy greens are relatively low in calories, making it possible to significantly increase the nutritional value of the diet without substantially increasing its caloric content.
Asbestos is a group of naturally occurring fibrous minerals that were widely used in construction and industry due to their strength and fire-resistant properties.
Although the physiological changes of pregnancy develop simultaneously across many systems, different processes may dominate at different stages. In early pregnancy, hormonal shifts, restructuring of vascular tone, activation of the thyroid gland, and increased toxic load associated with the processing of a large volume of hormonal metabolites are more pronounced. In mid-pregnancy, the increasing metabolic load and the expansion of circulating blood volume come to the forefront. In late pregnancy, mechanical and compressive factors related to uterine growth become more prominent.
Pregnancy is a period when the body begins to function under significantly altered conditions. Within a short time, the systems of circulation, digestion, hormonal regulation, immunity, metabolism, and the functioning of internal organs undergo restructuring. These changes are normal and are aimed at the development of the child; however, they require a large amount of resources and stability of all physiological processes.
Many people believe that if their cholesterol level is normal, their heart is safe. However, statistics show the opposite: heart attacks and strokes often occur in people whose test results do not raise any concerns.
One of the reasons for such “unexplained” cases is lipoprotein(a) or Lp(a) - a little-known but extremely important marker of cardiovascular risk.
The speed and pattern of aging differ for each person: in one, blood vessels are the first to be affected, in another — the joints, and in a third — the cognitive sphere. Therefore, an effective program must be based on objective data, not only on the clinical picture.
Aging is a natural biological process that affects every level of the body’s functioning. Over time, the ability of cells to repair themselves declines, damage accumulates, and adaptive mechanisms weaken. But the pace and manifestations of aging vary greatly from person to person: some remain active and mentally sharp well into old age, while others experience significant decline as early as middle age.
Mercury Is Not a Single Substance, but a Group of Chemically Distinct Compounds. Each form of mercury affects the human body differently. Its form determines how it enters the body, how quickly it is eliminated, how easily it accumulates, and which systems it damages—ranging from the respiratory tract to the kidneys and brain.
Mercury is a unique substance: it is the only metal that exists in a liquid state at room temperature. Thanks to its unusual properties, it has fascinated people since ancient times. It was used in medicine as a remedy, in alchemy as an “element of transformation,” and later in industry—for making mirrors, thermometers, lamps, and other products.
