Hazards of Chemical-Based Mosquito Repellents

Around the world, millions of people make use of chemical-based mosquito repellents to get complete protection from mosquito bites. But the most common insect repellents and bug sprays used in several homes may be poisonous and are able to produce health problems in people especially for the children. They also pose many adverse effects to the life of pets along with the destruction of ecological balance of the nature. Even if the chemical ingredients present in these chemical-based mosquito repellents can effectively kill the mosquitoes in your home and locality, it can seriously harm your domestic animals, fishes and even plants.

To the chemicals in the environment, individuals have different tolerances. In the case of insect repellents, children are the most vulnerable group. With the exposure to chemicals, young children are susceptible to change in their brain chemistry. This is because of the fact that the skin of children tends to absorbs more chemicals. In addition, this can harshly result in impaired growth; and affect the development of the nervous system.

Some chemicals are even known to bring about genetic damage to animals along with the enumerable toxic issues that have been listed in human. Prolonged skin exposure to these chemicals produce skin allergies, eye irritations, redness, skin discoloration and inflammation. Constant and heavy exposure to chemical repellents can also cause breathlessness, constant fatigue, muscle and joint pain, generalized physical weakness, memory loss and persistent headaches. People typically develop tremors and shortness of breath when overexposed to the strong chemicals in these repellents.

DEET is a registered chemical ingredient that forms the active component of every chemical-based mosquito repellents. Chemical repellents that include DEET when applied on the topical areas easily penetrate into the skin to our blood stream and cause adverse health hazards on our central nervous system. DEET is also easily absorbed by the human’s gut to cause further more health hazards. Permithrin is another chemical that when combined with DEET can cause chronic memory dysfunction and motor deficits. Some DEET repellents also contain toxic chemical substances like isopropyl alcohol and ethyl that are highly harmful for children.

There are lots of botanical and natural mosquito repellents available in the market today that are effective in warding off mosquitoes without causing any health hazards.

How to Identify the Symptoms of Malaria?

Normally it is found that a malaria infected person begins to show the symptoms within 10 to 30 days after the bite from the infected mosquito. The infection can result in recurrent attacks and symptoms that can vary from mild to severe depending on the type of plasmodium parasite the person is infected with. The infection with plasmodium falciparum can show symptoms within 7 to 14 days, other types like plasmodium ovale and vivax begins to show symptoms during 8 to 14 days and plasmodium malariae takes 7 to 30 days. But there can be differences in these timeframes depending on the individual.

A person may experience mild symptoms like fever, chills etc and can also have severe symptoms like kidney failures, coma etc. Even the severe cases can be cured well with prompt and proper treatment. Most of the symptoms are not continuous and can appear and disappear during the time frames. The reason behind this is that the parasite is completing its lifecycle by developing, maturing and reproducing and thereby again infecting more and more blood cells and liver cells. In the case of mild malaria symptoms may last for six to ten hours and then gets better. The recurrence of the symptoms varies from type to type.

Generally mild symptoms include moderate to severe shaking chills, fever, sweating followed by lowering of temperature, rigors, head ache, vomiting, diarrhea, nausea, slight jaundice, loss of appetite, abdominal pain, cough, enlarged liver and spleen, muscle or back pain, anemia and general fatigue. The severe cases normally occur due to plasmodium falciparum which can result in organ failure, problem with blood and metabolism. The general symptoms in severe cases are kidney failure, seizures, mental confusion, coma, severe anemia, pulmonary edema, acute respiratory distress syndrome, bleeding associated with problems in blood clotting and even death.

It is always advisable to take preventive measures in order to stay protected from malaria. The stagnant water where the anopheles mosquitoes breed must be emptied and you must protect yourself with an effective mosquito repellent in order to avoid mosquito bites. Try to use natural mosquito repellents so that you need not have to worry about the deteriorating side effects. Nowadays an effective soap is developed after a research done in Australia and china for competent mosquito protection namely Skin Armour deep woods outdoor soap. This soap from Skin Armour is made purely from efficient natural oils that can repel the mosquitoes for long hours.
