why do your pupils get big on drugs

You look in the mirror and notice that the dark circles in the middle of your are bigger than usual. What's going on? Those dark circles are your pupils, the openings that let light enter your eye so you can see. Muscles in the colored part of your, called the iris, control your pupil size. Your pupils get bigger or smaller, depending on the amount of light around you. In low light, your pupils open up, or dilate, to let in more light. When itвs bright, they get smaller, or constrict, to let in less light. Sometimes your pupils can dilate without any change in the light. The medical term for it is mydriasis. Medicines, injuries, and diseases can all cause this eye condition. A few medicines can affect the muscles that control your pupils and prevent them from getting smaller when light

 why do we need to wear sunscreen

why do we need to wear sunscreen

Everyone needs sunscreen to protect their skin from damaging UV rays from the sun and sunburn. Using sunscreen products decreases the chances for sunburn and can prevent skin cancer or malignant melanoma. According to the American Cancer Society, in 2009, more than 1 million people were expected to be diagnosed with skin cancer and research studies link skin cancer with sun exposure on unprotected skin. The sunвs drying rays also prematurely age the skin and lead to wrinkles. Your skin responds to excessive sun exposure by turning red, becoming hot, and slightly painful to the touch. Severe sunburns cause skin blistering and peeling. The sunвs rays have two types of harmful UV rays--UVA and UVB. UVA rays penetrate your skin more deeply than UVB and are the cause of premature skin aging.

 why does my scalp itch after i wash it

why does my scalp itch after i wash it

What do you recommend? First, you must treat the cause. There are highly effective treatments for the scalp disorders that I just described. If the source of irritation is external, I explain to the patient that it is very important to use gentle shampoo, thoroughly rinse the hair and not use keratolytic shampoo on a daily basis. There are also cosmetic products that can be applied after washing hair to soothe overly sensitive scalps. Blow drying and styling hair must be done gently. I also explain that it is important to avoid stressful situations as stress can trigger increased sensitivity. Itchy scalp has multiple causes, ranging from skin conditions such as dry skin, dandruff and psoriasis to underlying health concerns like iron deficiency anemia and liver disease. However, if your

 why does my cat shit on the floor

why does my cat shit on the floor

There's your first problem. Cats are very clean by nature -- in addition to regularly cleaning out the entire thing, you should be scooping at least every day. I admit I am really bad about this myself. The general rule is that most litterbox problems are psychological--they either don't like the condition of the litterbox or they don't like the location (too loud, too dark, too busy, smells odd, etc). Try scooping every day for starters. If there is still a problem, find a new location for the litterbox (make sure he knows where it is) and see if that helps. The tip about not using strong-scented cleaners when you're cleaning it is a good idea, too, as well as the possibility that he might not like the enclosed feeling with the lid. I'd be willing to bet that it's a psychological issue

 why does a younger man want an older woman

why does a younger man want an older woman

A few months ago a study came out that broke the hearts of women everywhere. Researched and compiled by the fine people at OKCupid, it revealed that when it comes to what men really want in a woman, it's youth. Do you remember that study? You know, the one that basically said that if you're a woman over 22, you should just give up and crawl under a rock somewhere? I'm sure you do, as much as you tried to forget it. Along with sharing that depressing news it also shared this painful line: "Once a woman passes the age of 22, she becomes exponentially less attractive to men. " Oh, how lovely. And while that still may be true for some men whose fear of ageing keeps them grappling like a rabid vampire for a woman young enough to be their daughter or granddaughter, another study has come out
