Sun and heat allergies are like regular allergies and are an immune system response to a substance that is normally harmless. Having true heat and sun allergies will occur only in certain people that are sensitive. It is not clear why some people will develop allergies to the sun and heat and there is evidence that some forms are inherited.

Some people have an allergic reaction to the sunlight. The body will be able to tell when it is about to have a dangerous reaction to sunlight and it will trigger up an allergic cascade. The sun allergies are usually going to appear on the exposed skin as a rash or hives. There are usually two forms of sun allergies that can happen to the body. They are going to be polymorphous light eruption and solar urticaria.

Some of the conditions that are thought of as sun allergies are usually skin disorders that are caused by a combination of an ingested or some type of cream that is applied to the body and then going out into the direct sunlight. This will sometimes cause a combination that is painful and will be considered an allergic reaction to the sun.

There are also people that have sun and heat allergies that are going to be very scary. Sometimes if a person is out in the sun too long, they will get heat exposure and this can feel like sun poisoning. This is going to make a person feel sick and very upset. Having too much sunlight in your life can be harmful just as not having enough. Heat allergies can be caused by the sun or by sweating and even hot showers. This can create hives on most of the body. Heat allergies can also come in two different types and they are prickly heat and heat urticaria.

Getting the facts on sun allergies is going to be a good way to keep yourself safe and to make sure that you are not exposing yourself to sun allergies. It is no fun to not be able to go outdoors and enjoy the great sunshine. You have to keep your body protected at all times and make sure that you are able to keep any sun allergies under control.

It is important to be careful when you are out doors and in the heat. You need to make sure that you are keeping yourself safe from the heat exposure and what is going on. You need to apply lots of sun block and make sure that you have some type of shelter from the heat and sun at times. You should also make sure that you are drinking plenty of fluids especially lots of water to keep you healthy and strong when you are out in the hot sun for any period.

When it comes to looking older your skin is the feature that most reliably tells your age. A study by experts at Case Western Reserve Medical School in Cleveland using twin subjects finds that lifestyle choices, including smoking, being overweight, not using sunscreen, all take a toll on already sun damaged skin and lead to the appearance of aging skin.

Twins were used because they allow researchers to exclude genetic factors (as twins have identical genes) and more accurately judge the effect of lifestyle and environment on the skin.

The work involved collecting data on 65 pairs of twins (fraternal and identical) who were part of the 2002 Twin Days Festival in Twinsburg Ohio. The subjects were asked about their skin type, smoking and drinking habits, their weight and if they had any history of skin cancer.

Skin damage was similar in both identical and fraternal twins, but factors outside of genetics are linked with more skin damage.

The study authors found that long-term sun exposure brings both physical and structural changes to your skin that cause damage. Sun damaged skin has a more coarsely wrinkled surface, extra pigment or spots, lost pigment or dilated blood vessels instead of the fine wrinkles and skin growths you'd normally see in aging skin not damaged by the sun.

In fact, as much as 40% of aging-related changes to skin come from either the environment or lifestyle choices according to the researchers. Environmental factors included a history of skin cancer, being overweight and smoking.

Drinking was found to bring less skin damage. While added weight usually makes you look older, it was also found to hide damage to the skin because the weight fills out the face. One surprise from the research was the skin cancer rate - higher among twins than in the general population.

"This study, with an 8 percent skin cancer rate in twins, seems high when the general population has an incidence of less than 0.5 percent. This in of itself would merit further examination to look at other [potential risk] factors, such as prenatal x-rays, prenatal sonograms and low birth weights," points out Dr. Jeffrey Salomon, who wasn't involved in the study but is an assistant clinical professor of plastic surgery at Yale University School of Medicine.

To assess damage to your skin, stand in front of a mirror and hold up either arm so that the unexposed part is next to your face. If the skin of your arm is softer and smoother than the skin on your face, you have damaged skin. While you can't change what's happened so far, there are things you can do now... today, that might just help keep your skin looking younger and fresher.

- Avoid the sun - it's your skin's mortal enemy, so be sure to use daily UV protection (in a moisturizer or sunscreen) as well as avoiding being in the sun during the peak hours of 10:00 am - 2:00 pm or wearing protective clothing if you must be outside.

- Stop smoking - as this causes your skin to age early, robbing it of oxygen and nutrients, as well as causing the breakdown of your natural stores of collagen and elastin.

- Drink plenty of water - as this hydrates your skin from the inside out. Eight to ten glasses per day, which sounds like a lot, is good for your skin.

- Exercise - regular activity gives you skin plenty of oxygen so it stays healthy, as well as being a great way to keep your body fit and your weight under control.

- Exfoliate 샌즈카지노 - to remove dead skin cells from the surface of your skin. Exfoliated skin is better able to absorb and benefit from the creams or moisturizers you're using.

- Daily moisturizing - in the morning and night helps aging skin hold on to its elasticity. You might try vitamin C creams for winkle control and fading of brown spots, products with alpha hydroxy acids to keep your skin younger looking.
