Treating sunburn and reducing
skin damage
Understanding what sunburn is
and how it can happen, will enable you to have effective treatment of sunburn.
It will also show you how to reduce skin damage from the sun.
What is sunburn?
When your skin (that of
others or animals) is over-exposed to the ultra violet rays from the sun, the
skin tissue may be burned by UV radiation. Normally, short periods of exposure
to the sun are not harmful to your skin. In fact, a moderate amount of sunshine
helps to produce melanin, which acts as the skin's natural defense or as a
photo-protectant. It results in a healthy looking sun tan, which is
aesthetically pleasing.
When you are sunburned during
prolonged exposure to the sun, you may begin to experience mild symptoms of
discomfort, which include red or reddish looking skin that begins to feel hot
to touch. This can happen within the first fifteen minutes of exposure,
depending upon the intensity of the sun's UV rays. Try to avoid sun exposure
between the hours of ten am and four pm, as the UV rays are the most intense
during those times. That is the time when you are the most likely to
experience a severe sunburn. Note that you may not be aware of the sunburn until some time later, when the redness of your skin will make it increasingly
obvious.
If you start to experience
fatigue and dizziness, stay out of the sun. Prolonged exposure to the sun can
turn into a life-threatening situation.
Other symptoms of sunburn may
include headache and nausea. Your skin may begin to feel tender to touch or
become painful. Blisters may start to form and a skin rash may appear. You may become
feverish and experience edema. Your skin will probably feel dry, itchy and
start to peel within a few days. Note that sunburn can result in first or
second degree burns, but the degree of damage does not always correspond to the
amount of redness. Thus, when you are sunburned, it may not necessarily show up
as reddish skin, immediately.
There are two kinds of cancer
that are the result of sunburn, namely basal cell carcinoma and squamous cell
carcinoma.
Importantly, sunburn and the
increase in melanin production are triggered by direct DNA damage. When the skin
cells' DNA is damaged by UV radiation, type I cell-death is triggered and the
skin is replaced. (1)
The skin attempts to protect,
as well as repair itself naturally, when damaged by UV rays from the sun. The
skin may take several days or weeks to return to its normal state, but this
depends upon the degree of skin damage that has been sustained. If there is a
severe sunburn, it could take longer.
Malignant melanoma may occur as
a result of indirect DNA damage, if the damage is not properly repaired. Proper
repair occurs in the majority of DNA damage and as a result not every exposure
to UV results in cancer. (2)
What is a malignant melanoma?
A cancerous skin condition or a
melanoma lesion may suddenly appear on the skin after prolonged exposure to
the sun. A melanoma is asymmetrical in appearance and darker around the edges
than it is at the center. It may also change color. If you find that you have a
suspicious looking lesion that is larger than one quarter of an inch in size,
it is advisable to consult a physician, who may refer you to a
dermatologist.
What treatments are effective
for the treatment of sunburn?
Lidocaine and benzocaine are
anaesthetic pain relievers that can be applied topically, as ointments or
sprays. Applying Aloe Vera or Vitamin E cream to the sunburned area, may help
to relieve itchiness and dryness. Hydrocortisone cream or ointment may reduce
the amount of inflammation.
Applying a towel soaked in cool
water may help to reduce the itchiness and swelling. Water, to which a small
amount of white vinegar has been added, may help to reduce itchiness and
swelling.
Note that ointment or lotion
should never be applied directly to any open burns. Butter should not be
applied to the skin either.
Medication for headache or
fever may include analgesics, like acetaminophen. Non-steroidal
anti-inflammatory drugs (NSAIDS) such as salicylates, may be prescribed for
pain and inflammation. Ibuprofen and naproxen may be effective in treating sunburn.
Note that ASA is not recommended for children, as it may cause Reyes disease.
There is no known cure for
sunburn. If you are recovering from sunburn and have to be in the sun for some
reason, limit the length of time you are exposed to short periods only and
avoid direct or prolonged sun exposure, as much as possible. Keep your previous sunburned skin covered.
Remember this old saying? ‘An
ounce of prevention is worth a pound of cure.’
To prevent serious sunburn in
the future, take the following measures. When you are aware that you
will be exposed to the sun for long periods of time, wear light-weight cotton
clothing, particularly during the hours when the UV rays are at their highest.
Avoid wearing polyester clothing, as it may block the circulation of oxygen.
Your clothing should include long sleeve shirts and long pants. Wear
light-weight summer shoes and light cotton socks instead of sandals, to protect
your feet from being sunburned. A wide brim, cotton hat will be cooler and help
to protect your face, nose and ears. Sunglasses will prevent eye damage from UV
rays.
If you are sitting outdoors for
extended periods of time, stay in the shade. Relax beneath a tree or under a
picnic umbrella placed over your lawn chair or picnic table.
Do online inquiries and learn
about the UV index. Note that UV levels become higher, as one moves closer to
tropical areas.
Wear sunscreen and sun blocks
with a high sun protection factor (SPF) and re-apply them to your skin,
approximately every two to three hours when you are in the sun, as this will
help to block skin damage from UV light. If you are going to be in the water,
make certain that you are using a waterproof sunscreen or sun block.
Several foods and fruit that
appear to offer some degree of protection from sunburn include those with high
levels of beta-carotene (carrots) and lycopene (tomatoes). Eating dark
chocolate several hours prior to exposure, is recommended.
Note that sunburn can result
from other UV light sources, like welding. Welding helmets and protective
clothing should always be worn to protect the skin. Protective glasses and
shields should be used by welders.
Skin damage from UV rays, can
occur with sun lamps or sun beds, particularly when there is prolonged exposure.
Exposure to ultraviolet germicidal irradiation may cause sunburn.
Enjoy the sun, but take the
necessary precautions. Note that this information on how to treat sunburn and
reduce skin damage, has been been obtained from the following web site.
