Weekly Health Quiz: Breathing, Hydrogen and Alzheimer's

1 Molecular hydrogen has been scientifically shown to:

• Increases the pH of the water making it alkaline
• Have antioxidant effects that specifically target the most harmful free radicals

  Molecular hydrogen (H2) is a gas with very unique and selective antioxidant effects that specifically target the most harmful free radicals. The alkaline water fad was an unfortunate outgrowth of the successful use coupled with a misunderstanding or ignorance of the therapeutic property of the water (e.g., benefits falsely attributed to alkaline pH and not the actual H2 gas).

• Be an ideal replacement for hydrogen peroxide
• Have pro-oxidant effects that may be harmful to health

2 In any given flu season, influenza viruses are responsible for how great a percentage of all respiratory infections?

• 80 percent
• 60 percent
• 20 percent

  Noninfluenza type viruses are responsible for about 80 percent of all respiratory infections during any given flu season, and the flu vaccine does not protect against or prevent any of these instances. Learn more.

• 40 percent

3 Research by the National Toxicology Program in the U.S. has found:

• No evidence for heart tumors in male rats exposed to 2G and 3G cellphone radiation
• No evidence for DNA damage in rodents exposed to 2G and 3G cellphone radiation
• Clear evidence of brain tumors in all rodents exposed to 2G and 3G cellphone radiation
• Clear evidence for heart tumors in male rats exposed to 2G and 3G cellphone radiation

  Research by the National Toxicology Program found "clear evidence" for heart tumors in male rats. These tumors started developing around week 70, and are similar to human acoustic neuromas that previous studies have linked to cellphone use. Learn more.

4 Recent research suggests you can slow down the rate of cognitive decline by 50 and 75 percent respectively, by:

• Restoring vision and hearing

  Research suggests you can slow down the rate of cognitive decline by 75 percent by restoring your hearing with hearing aids, and by 50 percent by restoring vision through cataract surgery. Learn more.

• Restoring insulin and leptin sensitivity
• Sleeping less and exercising more
• Lowering your cortisol level and improving your physical fitness

5 Besides diaphragmatic breathing, exercise and maintaining good posture, which other measure has been implicated as helpful to increase your lung capacity?

• Taking deep breaths through your mouth
• Optimizing your vitamin D level

  Quitting smoking and optimizing your vitamin D level are other measures shown to promote increased lung capacity. Learn more.

• Switching to e-cigarettes
• Sleeping with your windows open

6 Facebook's data collection and sale of your personal information can negatively affect you by:

• Opening you up to be a target for manipulation and deceit
• Being sold things you don't need by targeted ads based on your preferences
• All of the above

  Giving out personal data opens you up to be a target of manipulation — whether you're being manipulated to buy something you don't need or believe something that isn't true. Facebook also allows for the propagation of propaganda at an enormous scale, effectively turning disinformation into a weapon capable of upturning governments and cause bloodshed. Learn more.

• Inciting social unrest or governmental upheaval based on lies

7 Statin drugs raise your risk of Alzheimer's disease by:

• Destroying muscle
• Inhibiting blood flow to your brain
• Lowering your blood sugar
• Inducing Type 2 diabetes

  Use of statin medication is associated with a 41 percent higher risk of Type 2 diabetes in men and a 71 percent higher risk for women. Type 2 diabetes in turn raises your risk of Alzheimer's three- to fourfold. Learn more.
