How can I prevent athletic performance anxiety?

I compete in an individual sport. The problem is that on the day of a major competition, I have really bad indigestion. Sometimes, I have to run to the bathroom every half hour for a bowel movement! Besides being annoying, disgusting, and a little embarrassing, this interrupts my competition and adds unneeded stress. Why is this happening and what can I do to prevent it?


Is it dangerous to hold in number two?

My boyfriend and I have been together for almost three years, and we've lived together for more than one, but I still can't do Number Two when he's in the house. It's not a problem during the week when we both go to our separate jobs, but on the weekends, it's usually just the two of us in the house all day (and night) Saturday and Sunday and if I feel the need to poo, I have to wait until Monday. My question is this — are there any adverse health issues I should be concerned about with waiting to poo? I know that holding your pee can give you bladder infections, but is there a similar issue with Number Two?


How can I cure a sunburn?

I was in the sun for seven hours yesterday and I got a pretty bad sunburn. My face has blisters all over it. The redness is severe, and the pain is severe. Any suggestions that you may have will help. To top it off, I am a diabetic and am worried about infection of the blisters.


What are the differences between sun protection products?

I find choosing among all of the available sunscreens and sunblocks to be very confusing. Of the following three products I am currently using, which one is giving my skin the most protection: sunscreen SPF 30 with UVA, UVB, and IR sun protection; sunblock SPF 17 with UVA, UVB, and IR sun protection; or, sunblock SPF 50 with UVA and UVB sun protection? By the way, what is the difference between a sunSCREEN and a sunBLOCK?


What are the risks of gel and shellac nail manicures?

I love getting my nails done with a gel or shellac manicure. The polish doesn't chip at all and stays shiny for weeks. I'm just worried about the UV light used to seal the manicure - it is almost like a mini tanning bed for your hands. What are the risks? And are there any bad chemicals in the polish?
