The earth's atmosphere filters out UVC radiation, but UVA and UVB affect you every day. UVB affects the top layers of skin, while UVA penetrates to the deeper layers. Your hair and your skin are negatively affected by these UV rays, although they appear to react differently. A pigment called melanin determines the color of your skin and hair. One form of melanin is a reddish-yellow color, while the other is brownish-black.
Corinna Davie | Biology | , 2013 Evaluate the effects of smoking assignment three of three Introduction In this assignment i am going to analyze the effects smoking has on the human body. I am also going to compare one cancer or disease created by smoking with a positive asset that smoking can provide. When i have done this i will conclude my evaluation with the question "Do the positives outweigh the negatives?" Negative affects smoking has on the human body Figure 1 shows the areas that smoking can cause harm How Smoking Affects The Human Body Negatively Hair | * Toxic chemicals in smoke can damage DNA in the hair follicles. * Smoking can generate cell-damaging free radicals (oxidation stress on hair).
Sty is an infection involving a hair follicle on the eyelid, usually by staphylococci. It can become a chalazion an oil gland fully blocked. This can cause vision impairment. Symptoms of a sty include: Red swollen pimple (bump) Gritty, scratchy sensation Sensitivity to light (photophobia) Tearing of eye Tenderness of the eyelid Treatments for sty include: Warm compresses to eye Drain on its own Antibiotic creams Lanced or drain the infection If the sty infection is not treated it can lead to vision impairment or even loss. It can be spread to the other eye.
These objects become contaminated through direct contact with infected eye discharge or from hands that were not properly washed after touching an infected eye. If you have symptoms of pink eye, you should seek prompt medical attention. Other problems, like abrasions or foreign bodies in the eye, can produce similar symptoms and need to be ruled out. A culture of the eye discharge may be needed to know what type of antibiotic will be most effective. There are a few symptoms from pink eye that you should defiantly know about like, red eyes, clear or cloudy eye discharge, light sensitivity , matting of eyelashes, especially in the morning and itching of the eyes.
- The overexposure to ultraviolet radiation is “the primary environmental risk factor in the development of UV-related adverse health effects, which include diseases of the eye, immune suppression, and skin cancers” (Goddard News, n.d.). All of the effects have a high level of importance, because two of them can lead a person to death if they are not treated properly and detected soon. UV radiation can also cause premature skin aging, making skin more wrinkled and rough. People need to understand that if a person overexposes to UV
Tanning salon owners (and their commissioned employees) regale us tales of how much worse tanning beds were “back in the day”. Let’s discuss! FACT: Newer models of tanning beds tend to use more UVA long range waves, compared to older beds using shorter wave UVB rays. However, UVA rays penetrate deeply and can weaken the skin’s connective tissues. Those are the same connective tissues that hold our skin to our cheekbones and jaw bones, allowing our skin to be taut and plump.
Further studies show that lightning may cause damage to the hair and scalp, so it’s important to have a professional colorist to do your highlights. Bleaching your hair can give you a lighter look. People tend to bleach their hair for styles and trends. When you bleach your hair it also can cause serious damage. The lighter you go on the hair the more damage it inflicts on it.
Free Dictionary by Farlex Humans are constantly exposed to a range of chemicals and toxins in their environment which can affect their health, including their reproductive health. For men, a range of environmental exposures are associated with reduced sperm concentration and quality. Men whose sperm is sub-optimal in either quantity or quality are less likely to conceive, and will, on average, take
There are many reasons why smoking cigarettes should be banned from our society because cigarettes cause more bad than good. People will experience more physical problems if they do not practice smoking abstinence. For example, because smoking is carcinogenic a smoker will be more likely to develop more problems than a non-smoker. First emphysema is a problem that usually develops when long term heavy smoking occurs. This condition occurs when inhaled irritants increase mucus secretion in the passage of the lungs causing severe coughing fits.
With that being said, in reference to the first paragraphs statement alluding to weather skin cancer is an inherited gene mutation or if it is due to exposure to the UV light. Let’s take a closer look to make it clearer; most fair skin, light hair, freckled, and light eyed people have a higher risk of developing skin cancer. However they HAVE to be exposed to sun light in order for it to happen. On the opposite side of that a darker skinned, darker hair and dark eyed person may not be as susceptible to skin cancer but if they are exposed for long enough and often enough they too can get skin cancer. In addition to them getting skin cancer it is more “likely” that they will get it in an area that isn’t exposed to the sun as often, i.e.
