If you hear your own voice on your cell phone while speaking during a call, you’re experiencing a common occurrence known as a sidetone. A sidetone is an echo effect that is the result of your phone diverting voice data to the phone’s earpiece on a slightly delayed basis. Several situations can cause a sidetone, most of which you can fix on your own.
The widespread use of new technologies often changes social and psychological aspects of person's life. Cell phones are a tool of communication, but unhealthy use of cell phones can actually hurt personal communication. Improper cell phone use can lead to social anxiety and social isolation. However, cell phone use can also help people better manage difficult relationships, such as long-distance ones.

It is considered an improvement over colloidal silver, which proponents also claim to have curative effects. While there is medical consensus about the value of the silver ion, which is used to dress wounds and kill bacteria, Molecula Silver's medicinal value is disputed.
Today's society relies heavily on cellphones for communication between friends, family members and business associates. Most people talk or text on a cellphone daily. While it has made communication more accessible, it also has negative impacts on the way that people communicate with each other on a regular basis.
Yellow 5 coloring (FD&C Yellow No. 5) is a lemon yellow-colored dye that is synthetic and water-soluble. It is added to products to make up for color loss due to processing and storage conditions, to correct natural changes in color, to enhance natural colors or to provide color to foods that would otherwise have little or no color at all. It is used in a variety of foods, drinks and cosmetics.
Hold a lead crystal stemware or decanter up to the light. Watch the light refract through the heavy crystal. You know you are holding a valuable piece of glassware. Use the lead crystal for food or drink, especially storage, and you expose yourself to health hazards. The extent of the hazard depends upon your age and the type of use.
Gamma rays are high-frequency waves emitted by stars and radioactive substances. Because the waves can easily pass through most material, avoiding gamma ray exposure requires a shield of lead or concrete. High-intensity gamma-ray bursts can come from bombs, supernovas and equipment used to treat cancer. High levels of gamma ray exposure has negative health effects on living tissue and cells.
Blood disorders define any abnormality with the blood, including abnormally or odd-shaped blood cells. Red blood cells carry vital oxygen and nutrients to all organs, tissues and cells of the body. Any abnormality in their shape affects their function. Understanding how abnormally shaped blood cells can affect your health encourages people to be aware of the benefits of various treatments which may improve blood health and body functions.
Cell phones work by emitting radio waves which transmit communications. The proximity of the phone to the human head while in use, and concerns about the effects of prolonged exposure to even low levels of radiation, have prompted questions about cell phone safety. The electroencephalograph (EEG) is a graphic record of electric activity in the brain. EEG activity--brain activity--is generally constant, although there are patterns characteristic of waking and sleep states. EEG tests often measure changes in responses when subjects are asked to perform simple tasks or respond to stimuli. A change in EEG response is not of clinical concern,…
Driving a motorcycle may look like fun, but it's dangerous. Motorcycle accidents in the United States cause more deaths---usually from head injuries--- than any other kind of vehicular crash. Among survivors, painful injuries to legs, hips, arms and lower back are common. Serious accidents may cause brain damage or paraplegia, paralysis from the waist down. In some cases, a crushed leg may require amputation. Along with physical pain, survivors may experience forms of psychological distress.
Cell phones became prevalent in the United States in the early 1990s and their usage has steadily increased since. To support the now great number of cell phone users, companies construct cell phone towers (or base stations) in many areas. The cell phone towers emit and receive radio frequency (RF) signals which many people fear pose serious health risks, even increasing the likelihood of cancers.
About five billion cell phones are in use worldwide today. This technology has sparked a new controversy over the health effects and safety of the hand-held devices. The GSM Association, which represents the cell phone industry, estimates that more than $100 million has been spent worldwide on research into health risks from mobile phone usage. A major public health concern is the radiation produced when the devices communicate with their base station. Wireless phones transmit via radio frequency, a low-frequency form of non-ionizing radiation (unlike ionized radiation exposure in a CT scan). It is unclear if frequent low-dose radiation exposure…
The explosive popularity of mobile phones has moved scientists and doctors to study the devices' potential ill effects on human health. The studies have revealed that the phones do pose some risks, whether from merely touching them, or from actually using them.
Cell phones are useful pieces of technology to have nowadays, and they can keep you connected with friends, family, and business contacts more easily. While they may make life a little more convenient, however, they do carry with them some risks and side effects. Although researchers are still trying to determine the side effects of cell phones, you should be aware of the actual and potential dangers involved in using them.
Forklifts are mobile vehicles equipped with prongs or forks, and are used for transporting and lifting heavy loads. Workers in junkyards, construction sites, warehouses and many other areas use forklifts on a daily basis, although they may not always be operating them properly. According to catalog.blr.com, the U.S. Occupational Safety and Health Administration (OSHA) estimates that 100 workers die each year in forklift-related accidents, while another 20,000 are severely injured.
Yellow 5, also known as tartrazine, is a synthetic yellow dye commonly used in food coloring. Yellow 5 is found in many foods, including soda, cotton candy and mustard. The use of Yellow 5 is not limited to just food. It is also found in soaps, cosmetics and vitamins. Although the use of Yellow 5 has been approved by the Food and Drug Administration, it is banned in some European countries and has been linked to potential health problems.
Chewing gum has been a human habit since prehistoric times, and the production and sale of chewing gum today is big business that shows no signs of slowing down. People who chew gum regularly may want to know its good and bad effects, which depend on the ingredients used in a product and even the context in which the gum is chewed.
Although the elegance and beauty of lead crystal have led to its broad use in serving food and beverages, an element of caution is necessary when choosing to eat or drink from lead crystal stemware, dinnerware, or storage containers. This is due to the danger of the lead content in the crystal leaching into liquids and causing serious health issues. Lead is a highly toxic metal that is found in small amounts within the earth's crust. The amount of lead that dissolves into food and drink will depend on the lead content of the crystal, the type of food or…
The health effects of glass injuries range from the mild forms of abrasion to life threatening lacerations. Crushed glass itself has mild effects on health, though it can pose risks to sensitive areas of the body, like the eyes, if exposed to a large enough amount. A person working with such materials, like crushed glass, would be wise to take appropriate safety precautions, such as wearing gloves and goggles to avoid these potential injuries when working with crushed or broken glass.
Taking a sauna exposes your body to dry heat at very high temperatures. Saunas can have some positive health benefits for people. However, there are some potentially negative health effects associated with saunas, particularly for people with certain health conditions.
You may have heard that cell phones can have negative health effects, particularly with the human brain. Scientific research on the topic indicates divergent conclusions on the subject.
Beta glucans are a group of fibrous sugar molecules. They come from the cell walls of oats, barley, mushrooms or yeast. The source of the beta glucan determines what type it is. The effects of each type are similar, though each is thought to have its own specific health benefit.
Boric acid, also known as boracic acid, is a water-soluble chemical compound. It has been used as a mild acid since the 1700s. Boric acid is harmful to humans and other animals.
According to the Mayo Clinic, giant cell arteritis (also referred to as temporal or cranial arthritis) is an inflammation of the lining of your arteries. It most frequently develops in the head, particularly in the temporal arteries that split off from a blood vessel in the neck called the carotid artery. Corticosteroid medications usually offer prompt relief of symptoms and, in time, complete recovery is probable.
Many people believe cell phones cause brain tumors. However, the Federal Drug Administration (FDA) and other scientific authorities disagree with this belief. In fact, the major conditions associated with cell-phone use include physical strain, hearing loss, and neurological risks for children. What is certain is that cell phones can indirectly cause devastating physical injuries when they are used during driving and other activities.
