Is sunscreen Chemical Letha to Horse Shoe Crabs?
Avoid yourself shielding from the rays of the sun by slathering on chemical sunscreens. In which many of them are linked to skin cancer risk, as stated by clinical laboratory scientist Elizabeth Plourde, Ph.D.
A recent symposium highlighted the environmental dangers of emerging environmental contaminants. The environmental dangers associated with the use of sunscreen widely. According to University of Delaware marine biologist Danielle Dixon, oxybenzone chemical in sunscreens is lethal to horseshoe crab eggs.
Tips How to Use Sunscreen
1. Apply sunscreen all over the skin which is exposed to the sun.
2. Apply sunscreen 30 minutes before going to get exposed in the sun.
3. It is advised to re-apply the sunscreen after sweating, swimming etc.

Sunscreen Side Effects
Some of the side effects of sunscreen are:
The presence of a chemical in sunscreen leads to irritation, swelling, redness, and itching. Few people develop severe allergic reactions like intense itching and rashes. This allergic reaction can be a chemical reaction due to sunscreens such as fragrances and preservatives. PABA present in many commercial sunscreens that leads to allergic reaction. Many reputed brands removed PABA from sunscreen to avoid an allergic reaction.
Sunscreen with the label ‘hypoallergic’ is safe to some extent as other chemicals can lead to an allergic problem. It is better to get a patch test done by a dermatologist before using sunscreen. Sunscreen that contains zinc oxide is less allergic.
2. Sunscreen Makes Acne Worse
Some chemicals in the sunscreen product can worsen an acne problem. In order to avoid such problems, one can choose non-oily and non-comedogenic sunscreens. It is necessary to choose the sunscreen suited for your skin type. Body sunscreens are too heavy so never use it on the face.

Choose Safer Sunscreen for the Skin
There are so many sunscreens available on the market and it is difficult to find a safe one. The majority of sunscreen is risky for pregnant women, infants, and kids which contains endocrine disruptors. These can disrupt development and growth, leads to early puberty, and result in low sperm count and small testicle size in boys.
Never use sunscreens which contain oxybenzone, retinyl palmitate, and synthetic fragrances. The safe choice is cream or lotion with zinc oxide. It gives the best protection from UVA rays and it is stable. Next best choice is titanium dioxide.
Make sure the product
- Protects the skin from UVB and UVA rays
- Nano-sized particles not available in that product
SPF protects the skin only from UVB rays; within the ultraviolet spectrum which allows the skin to produce vitamin, D. UVA rays are dangerous which cause skin damage and cancer. Never use SPF above 50 sunscreens as it does not provide a much greater protection.
As per research stated by experts’ people using high SPF, sunscreens get the same amount of exposure to UV rays as those using lower SPF products.
Safe Sunning Tips
Spending in the sun regularly with simple precautions to protect yourself from overexposure is good to get health benefits.
1.Before applying sunscreen give your body the chance to produce vitamin D. daily expose 40 percent of the body to sunlight for a short period of time. Vitamin D reduces the risk of melanoma and internal cancers.
2. Stay out in sunlight in the early hours of the day for a short period of time. Apply safe sunscreen on the face or use hat to protect the facial skin from sun damage. Facial skin is thin and sun damage may lead to premature aging wrinkles.
3.If you are in the sunlight for long period of time cover up with clothing, hat, natural shade or umbrella. After optimizing daily vitamin D production a safe sunscreen can be applied on the face.
4. To avoid sun damage consume natural antioxidants diet. To maintain a healthy balance of omega-6 animal based DHA omega-3oils in your skin consume fresh, raw, unprocessed foods which deliver full of nutrients. It protects the skin against sunburn.
To protect the skin from sunburn and cancer consume fresh vegetables. It provides antioxidants which help to fight against free radicals caused by sun damage.
Is Sun Avoidance as Risky as Smoking
As per one study, more than 25,500 Sweden women between the age of 25 and 64 were observed for 20 years. Their sun exposure habits and confounding factors analyzed in a competing risk scenario. Women with regular sun exposure found to have a high risk for melanoma compared to sun avoiders. They also had a lower mortality risk due to vitamin D increased levels.
According to the researchers, women with sun exposure habits are having a low risk of cardiovascular disease and cancer compared to sun avoiders.
Nonsmokers who avoided sun exposure completely had a lifespan similar to highest sun exposure smoker group.
Getting regular, sensible sun exposure on the bare skin provides optimal physical and psychological health. It also helps to prevent chronic diseases. As stated in a scientific review by dermatologist Dr. Richard Weller, to get cardiovascular benefits to sun exposure is best. Sun exposure within the limit and early daytime are better.
Sun exposure provides tremendous benefits. Few important properties of spending time in sun include:
1. Subcutaneous fat metabolism increased
2. Pain killing properties
3.Human lifespan regulation.
4. Evening alertness improves with daytime sun exposure.
5.Metabolic energy conversion.
Hazardous Chemicals Present in Sunscreens
As per Researchers like Dixon note some sunscreen manufacturers have switched from oxybenzone to avobenzone without any study confirmation. Dixon stated avobenzone is not safe.
As per research by the center for disease control and prevention found 96 percent U.S population has oxybenzone in their bodies. This is the cause of reduced sperm count in men and endometriosis in women in the U.S.
It is stated other chemicals found in 70 percent of sunscreens that that can enter the bloodstream. It causes toxic side effects and hormone disruption.
Sunscreens contain vitamin A or retinyl palmitate and retinol which lead to skin cancer by increasing the speed at which malignant cells develop and spread.
Sunscreen sprays release toxic particles into the air. Inhaling this product is risky for children and adults.
Zinc oxide and titanium oxide often used in spray-on sunscreen products. These are safest as long as they are not nanosized but inhaling them is harmful.
As per other studies nanoparticles are able to cross the blood-brain barrier. If nanoparticles entered into lungs or penetrate the skin cause widespread damage to cells and organs, nervous system, immune system, brain, and heart.
As per some scientists that the toxic effect of nanoparticles depends on their size is being in the range of a virus, which will trigger the body’s immune system.
