We come across many people around us who are allergic to some smells like fragrance of perfumes or cologne. Every substance has a potential to become an allergen and induce allergic responses. The exposure of the body to any chemical in large doses can pose a problem. Perfumes and colognes are neither toxic nor potent drugs and when used in small quantities are taken by the body as part of the routine cleansing action. Moreover, the quantity of chemicals used in them is also not very large. But if you are using them in large amounts, that too frequently, there are strong chances that you might become allergic to it.

AIDS, Acquired Immuno Deficiency Syndrome, characterized by gradual deterioration in the immune system of the body is caused by the HIV virus. HIV can infect your body through fluid contact with another organism suffering from AIDS. There is no such treatment which can cure the disease permanently but through anti retro- viral therapy, the effect of the virus can be controlled and the severity of the disease can be reduced. Using this therapy, the growth and multiplication of the HIV virus can be reduced to the minimum possible rate but it is now noticed that over time the virus starts multiplying frequently and immune system consequently falls off.

But, this is not a one- fit- for- all solution and changes as per, gender, activity, family history, present health condition and so on.

For calculating the calorie needs of the body, we divide the energy requirement in three parts: basal, activity and digestion energy.
