Truth or Myth?

  • Myth: Running a fever when you’re sick weakens your immune system.
    • A higher temperature in the body speeds up the functioning of cells, including the immune cells, increasing their rate of response to invading germs.
  • Fact: Allergies are caused by an overactive immune system
    • Allergy symptoms occur when your immune system reacts to a normally harmless substance.
    • In a severe reaction to an allergen, one may develop rashes over large areas of the body, have breathing difficulties, stomach cramps, vomiting, and may even have difficulty thinking as the brain becomes starved of oxygen. The brain and kidneys are especially vulnerable in this type of reaction because they may be permanently damaged even if the victim survives.¬†Also, cell fluids in the throat can cause the throat to swell and shut, leading to anaphylactic shock and death.
    • The only effective treatment as of now is an injection of epinephrine, which is a hormone the body produces naturally in the adrenal glands.Epinephrine constricts the blood vessels and opens the airways. However, these effects only last for 10-20 minutes per injection, and may have some serious side effects.
  • Myth: Cold weather makes you sick
    • Studies show that people are no more likely to get sick in cold weather than warm weather. It is rather being kept indoors and in confined spaces that increases ease of spreading germs.
  • Myth: Food quickly picked up from the floor is safe to eat.
    • Once food comes in contact with the floor, large amounts of bacteria is immediately picked up, making it unclean to eat, even if quickly picked up.
