You Might be Allergic to Your Smart Phone: Researchers recently analyzed 75 different types of cell phones to find which models contained cobalt or nickel, two common allergens, and found that one-third of all Blackberry phones contain nickel. Older, more traditional flip phone models contained high levels of nickel, too, but the Blackberry was the only smart phone with either one of the allergy-causing materials. Holding the phone up to your cheek for long periods of time can cause your face to react to the nickel, causing dry, itchy skin along your jawline and cheekbones. If you continue to use the phone, you may experience dark spots or scarring. Although an antihistamine will help with the irritation, the only way to “cure” the allergy is to get a new phone. Team iPhone wins again!

Exercise as an Appetite Suppressant: We all know what it feels like to finish a tough workout and immediately reach for high-calorie food as a reward. Although this is a common scenario, new research shows that after we should feel full following exercise. In a study, those who participated in a 12-week aerobic exercise program reported higher perceived fullness than those doing resistance training. There is no firm answer to why exercise suppresses our appetites, but it has been proven that there is some sort of relationship between exercise and hunger hormones.So why do we continue to reward ourselves with food? Experts believe that we often overestimate how many calories we burn during a workout, and so we end up sabotaging our weight-loss efforts. Reward yourself something other than food to fully reap the benefits of a work out.

“Female Viagra?”: Soon, this may be a reality. Researchers in Australia are working on a nasal spray that aims to increase sexual arousal in women. The spray contains testosterone, and by administering the spray 2-8 hours before sex, the women may have a better chance of experiencing an orgasm. The treatment is intended for women facing Female Orgasmic Disorder, meaning that they are unable to achieve an orgasm. It sounds promising, but critics wonder if the treatment would really work – female arousal and ability to orgasm are separate issues, they say, and fixing one will not fix the other.
