Illness due to lowered temperatures


Some studies imply that being cold cause illness. Some arguments indicate that if you’re cold, your body is more stressed and therefore less resistant to fight a virus. Research by Cardiff University’s Common Cold Centre in Wales has proven that a drop in body temperature can cause a dormant cold virus to develop.

If a person becomes chilled, for example by wearing damp clothes in cold weather, the blood vessels in the nose become constricted. When this occurs, the warm blood is closed off and no longer supplying the infection-fighting white cells.

One study involved the effects of volunteers placing their bare feet in an empty bowl for 20 minutes or soaking their feet in a bowl containing ice cold water for the same length of time. Within five days after the experiment, more participants who had soaked their feet in cold water developed cold symptoms than the other participants.

Lowered temperature settings can cause the body to be more immune to a cold and there are not suggested by professionals.

Magnetic treatment of water and its application to agriculture


In controlled large-scale field experiments it was found that magnetic treatment affects the quality of irrigation water. It was revealed that treated water contributes to an increase in farm yields in crop farming, yield being expressed in quantity and quality of the produce and in the specific economic contribution. The level of return in individual farms depends on three key factors: the type of equipment, the water quality, and the mode of operation of the apparatus.

The objective here is increased yields, improved quality, and higher operation efficiency of the irrigation water. The proposed magnetic treatment of irrigation and drinking water is intended for exactly the same purposes. The treatment is essentially physical, and its intensity increases with the rate of flow and with the electric conductivity of the water.

What are CO2 emissions

The troposphere is the lower part of the atmosphere, of about 10-15 kilometres thick. Within the troposphere there are gasses called greenhouse gasses. When sunlight reaches the earth, some of it is converted to heat. Greenhouse gasses absorb some of the heat and trap it near the earth's surface, so that the earth is warmed up. This process, commonly known as the greenhouse effect, has been discovered many years ago and was later confirmed by means of laboratory experiments and atmospheric measurements.

Life as we know it exists only because of this natural greenhouse effect, because this process regulates the earth's temperature. When the greenhouse effect would not exist, the whole earth would be covered in ice.

The amount of heat trapped in the troposphere determines the temperature on earth. The amount of heat in the troposphere depends on concentrations of atmospheric greenhouse gasses and the amount of time these gasses remain in the atmosphere. The most important greenhouse gasses are carbon dioxide, CFC's (Chlor-Fluoro-Carbons), nitrogen oxides and methane.

Since the industrial revolution in 1850 began, human processes have been causing emissions of greenhouse gasses, such as CFC's and carbon dioxide. This has caused an environmental problem: the amounts of greenhouse gasses grew so extensively, that the earth's climate is changing because the temperatures are rising. This unnatural addition to the greenhouse effect is known as global warming.

Pool safety hazards


Your swimming pool can offer up a cool, refreshing oasis away from the summer heat, but it can also harbor dangerous safety hazards beneath its shimmering surface. Educate yourself on some of the most common pool safety issues encountered by families and homeowners so you can take the necessary precautions to keep your family safe.

Drowning is one of the top causes of death for American children. Every year, 260 children under the age of five die in swimming pools. Never leave children unattended in a pool. If you must step away from the pool, ask a designated person to watch your children while you're gone.

Young children and babies can sometimes crawl or walk near a pool's edge where all it takes is a trip or a fall for them to end up in the water. This can also occur with your neighbor's children who may take a shortcut through your yard one day and fall unwittingly into the water. To keep such accidents at bay, put a fence around your pool. It should measure at least 48 inches in height and include a locking mechanism.

When your pool deck gets wet it can quickly become slippery. People walking or running on it can therefore slip and experience a painful fall. Minimize this risk by using nonslip coatings on your decks or sidewalks, which can include chemical treatments that texturize your concrete or simply rubber mats that you can lay across the deck.

If someone dives into your pool and it's too shallow he can experience broken arms or even a spinal injury. Ninety percent of swimming-related spinal injuries happen in water that's less than 6 feet in depth. Do not allow your family or friends to dive into your pool unless your pool's depth measures in at 8.2 feet or deeper.

The drains that keep your swimming pools water circulating can create a powerful force of energy. If you get sucked against the drain it can be so powerful that even adult swimmers can't break free. This creates both physical injury risks as well as risks of drowning. Always inspect your swimming pool before allowing people into it and don't let swimmers enter if your pool's drain covers are broken or missing.

Chemicals in cleaning products and their effects on the human body


Always read the label. You’ll find that there are some pretty dangerous chemicals, which float in the air of your home each time you clean:

·         Acetic acid (disinfectants)

·         Boric acid (cockroach/insect powders, water softener, germicide)

·         Carbolic acid (disinfectants)

·         Formic acid (deodorizing tablets and fumigants)

·         Hydrochloric acid/muriatic acid (metal/toilet bowl cleaners, bleaching agents)

·         Oxalic acid (disinfectants, household bleach, iron cleaner, anti-rust polishes)

·         Phosphoric acid (metal/toilet bowl cleaners, rust proofing, disinfectants)

·         Sulfuric acid (drain de-cloggers/cleaners)

These acids can burn the skin and may cause itchy rashes, blisters and erosions on areas of the body the acid comes in contact with. When ingested, it can burn or puncture the esophagus and stomach. Aside from the acids listed above, other products contain ingredients that have been proven to pose serious health risks

·         Triclosan can cause photo contact dermatitis, a skin irritation marked by itchy rashes and hives when exposed to sunlight. Triclosan is used as an anti-bacterial agent in antibacterial soaps, hand gels/sanitizers, and cleaning wipes

·         Neurotoxins poison the brain and nervous system and is said to lower a child’s IQ. Neurotoxins are found in air fresheners, disinfectants, spot removers and permanent-press fabrics.

·         Carcinogens have been found to cause or aggravate cancer
Carcinogens are found in all-purpose cleaners, dishwashing liquids, furniture polish, window cleaners, air fresheners, insecticides.

·         Endocrine disrupters interfere with body’s hormonal and reproductive system. Endocrine disrupters are found in laundry detergents, furniture waxes and metal polishes

·         Mutagens cause permanent genetic change in a cell. One example of a mutagen is Phenol, which is found in laundry detergents, all-purpose cleaners, air fresheners, disinfectants, furniture polish

·          Dermatogens interfere with fetal development and can be found in glass cleaners and all-purpose cleaners
