FAQ
What is the difference among a virus or bacterium and what are their differences?
A virus, a microscopic organism that can not reproduce outside of its host cells, is called a virus. A bacterium is an organism that splits itself in two. Viruses are very small (about 20 nanometers) while bacteria are larger (up to 1 micron).
Viruses can be spread by contact with bodily fluids containing infected substances, such as saliva, urine and semen. Bacteria are often spread via direct contact with contaminated surfaces and objects.
Viral infections can also be introduced to our bodies by a variety of cuts, scrapes or bites. They may also enter through the nose, mouth, eyes, ears, vagina, rectum , or anus.
Bacteria can get into our bodies through cuts, scrapes and burns, insect bites, or other skin breaks. They can also be introduced to our bodies by food, water and soil.
Both viruses and bacteria can cause illness. Viruses cannot multiply in their host cells. So they only cause illnesses when they infect living cells.
Bacteria can cause illness by multiplying in the body. They can spread to other parts of our bodies. Antibiotics are needed to eliminate them.
Does being cold give you a weak immune system?
It's been said that there are two kinds of people in the world; those who love winter and those who hate it. But whether you love or hate it, you may find yourself wondering why you feel so lousy when it's cold out.
The truth is that our bodies are built to function in warm temperatures. Our bodies were designed to thrive in hot weather because this is where the majority of our food sources are.
Now, however, we live in a completely different environment to how our ancestors lived. We spend more time indoors and are often exposed to extreme temperatures (cold or heat) and eat processed foods rather than fresh.
This means that our bodies aren’t used to these extremes. That means that when we do venture outdoors, we're left feeling tired, sluggish, and even sick.
There are many ways to avoid these side effects. One way is to make sure that you stay well-hydrated throughout the day. Hydration is key to keeping your body well hydrated, flushing out toxins and maintaining a healthy weight.
You must also ensure that you are eating healthy foods. The best way to maintain your body's optimal temperature is by eating nutritious food. This is particularly helpful for anyone who spends long periods of time inside.
It is worth taking a few extra minutes each day to meditate. Meditation can help you relax your mind, body and soul. This makes it easier to manage stress and illnesses.
How to measure body fat?
A Body Fat Analyzer will give you the most accurate measurement of body fat. These devices are used to measure the percentage of bodyfat in people who desire to lose weight.
What can be done to increase your immune system's effectiveness?
The human body consists of trillions of cells. Each cell works together to create organs and tissues that fulfill specific functions. If one cell dies, a new cell replaces it. Cells communicate with one another using chemical signals called hormonal hormones. Hormones control all bodily functions, including growth, development, metabolism, immunity and immune system.
Hormones refer to chemicals secreted in glands throughout the body. They circulate through the bloodstream and act as messengers to regulate how our bodies function. Some hormones can be produced within the body while others can be made outside.
When a hormone-producing gland releases their contents into the bloodstream, hormone production begins. Once hormones have been released, they travel through the body to their intended organ. Some hormones are only active for a brief time. Other hormones remain active longer and still have an influence on the body's functioning long after they leave bloodstream.
Some hormones may be produced in large numbers. Others are produced in small amounts.
Some hormones only are produced during certain periods of life. Estrogen, for example, is produced in puberty as well during pregnancy, menopause, old age, and after menopause. Estrogen assists women with breast development, bone density, and osteoporosis prevention. Estrogen promotes hair growth, and skin stays soft and smooth.

How To
What does the term "vitamins" mean?
Vitamins can be described as organic compounds found in food. Vitamins allow us to absorb nutrients from food. The body cannot make vitamins; therefore, they must be obtained from food.
There are two types vitamins: water soluble or fat soluble. Water soluble vitamins dissolve easily in water. Some examples include vitamin C,B1 and B2 vitamins (thiamine), B2 and riboflavin, B3 and niacin, B6 vitamins (pyridoxine), B6 vitamins (niacin), folic acids, biotin, pantothenic acids, and Choline. Fat soluble vitamins are stored in the liver and fatty tissue. You can find vitamin D, E K, A and beta carotene as examples.
Vitamins can be classified according to biological activity. There are eight major types of vitamins.
-
A - Essential for healthy growth and health maintenance.
-
C - important for proper nerve function and energy production.
-
D - essential for healthy teeth and bones.
-
E - needed for good vision and reproduction.
-
K - essential for healthy nerves, muscles, and joints.
-
P – vital for building strong bones.
-
Q – aids digestion and absorption.
-
R - Red blood cells are made from red blood cells.
The recommended daily allowance (RDA) of vitamins varies depending on age, gender, and physical condition. The U.S. Food and Drug Administration, (FDA), sets the RDA value.
For adults aged 19 and older, the RDA for vitamin B is 400 micrograms daily. Because it is essential for the development of the fetus, pregnant women should consume 600 micrograms per days. Children ages 1-8 require 900 micrograms per day. Children under 1 year old require 700 micrograms daily, while infants over one year old need 500 micrograms every day. This decreases between 9 and 12 months.
Children ages 1-18years who are obese need 800 micrograms per day while those who are overweight need 1000 micrograms per day and children who are underweight need 1200 micrograms per day to meet their nutritional needs.
Children aged 4-8 who have anemia are required to consume 2200 micrograms of Vitamin C daily.
2000 micrograms are required daily for good health in adults over 50. Mothers who are pregnant, nursing, or have a high nutrient need will require 3000 micrograms a day.
1500 micrograms is the recommended daily intake for adults aged 70+, as they lose 10% of their muscle every ten years.
Women who have been pregnant or are lactating require more than the RDA. Pregnant mothers need 4000 micrograms per daily during pregnancy and 2500 after giving birth. Breastfeeding mothers need 5000 mg per day when breastmilk is being produced.
