Beat the Heat this Summer ? 10 Sun Smart Ways to Stay Protected

As the summer season starts, it time once again to brush up your sun-safety practices and get set to beat the heat. With the continuing increase in the number of skin cancer cases, it has become extremely important to protect your skin against the negative effects of the sun.

Still, not many can resist the temptation of flocking to the beach or outdoor activities. This is why you need to know smart sun care ways. Bask all that you want, but make sure your skin stays protected against the harmful UV rays. Here are some tips:

1. Triple Sun Protection

If you plan to spend a lot of time out in the sun, like at the beach or tennis courts, make sure you lather on a triple layer of sun protection….

Cleanse your skin and apply an antioxidant based product to protect against free radical damage.
Apply a chemical sunscreen that prevents the sun rays from causing intrinsic damage. Consider using a double duty product like La Roche Posay Anthelios SX, a moisturizer plus sunscreen.
Top it off with a water and sweat resistant sun block, preferably one containing zinc oxide that will reflect most rays away from the skin’s surface.

2. Use Broad Spectrum Formulas

Use a sunscreen formula that shields against the UVB as well as the UVA rays of the sun. Some of the ingredients to consider are:

UVA Blockers – Mexoryl, Helioplex 360, active photobarrier complex, Avobenzone
UVB Blockers – Homosalate, Octosalate, Octylmethoxycinnamate
UVA & UVB – Octocrylene, Zinc Oxide, Titanium Dioxide.

3. Re-apply Every Couple of Hours

In order to ensure all-round sunscreen protection, you need to re-apply your sunscreen every couple of hours, especially if you are spending a lot of time outdoors. In fact, a general guideline is using a shot glass full of sunscreen over your whole body.

4. Use Half Teaspoon Sunscreen on your Face

If you do not apply enough sunscreen, it is not going to provide adequate protection. Ideally, use half teaspoon of sunscreen on your face.

5. Consider Powder Formulas for Oily Skin

If sunscreens feel rather oily on your skin try using powder formulations like iS Clinical SPF 20 Powder Sunscreen, a powder sunscreen available in translucent base and sun medium. It is a special nanotechnology formulation containing 25% titanium dioxide and 20% zinc oxide and provides sun protection against a vast spectrum of sunlight.

6. Wear Protective Clothing

While venturing out, try to wear longsleeves. Also, carry a hat or an umbrella to shield you from the damaging rays of the sun.

7. Eat a Fresh & Balanced Diet

Summer brings with it a variety of fruits and vegetables. So lay your hands on some fresh seasonal fruits and vegetables like pomegranate and blueberries. This will not just keep your skin hydrated but also supply essential vitamins and antioxidants.

8. Avoid Sun Susceptible Ingredients

If your skin is highly susceptible to sunburn, avoid using skin care products that contain glycolic or salicylic acid when you go out in the sun. These ingredients increase skin sensitivity to the sun and may cause a stinging sensation when you sweat.

9. Keep yourself Hydrated

Drink a lot of water, andbe careful if you drink alcohol or citrus beverages outside. Citrus fruits tend to make your skin more sun sensitive, while alcohol can dehydrate the skin. So, water is best..

10. Avoid Peak Hours

The sun’s rays are the strongest during 12 am to 4 pm. So make sure you try to avoid this time of day in the direct sun.! Try to schedule your outdoor activities in the early morning or evening.

Nanoengineering of Structural, Functional and Smart Materials

Product Description
In chapters contributed by 24 university & government laboratories, Nanoengineering of Structural, Functional, and Smart Materials combines wide-ranging research aimed at the development of multifunctional materials that are strong, lightweight, and versatile. This book explores promising and diverse approaches to the design of nanoscale materials and presents concepts that integrate mechanical, electrical, electrochemical, polarization, optical, thermal, and biomimetic functions with nanoscale materials to support the development of polymer composites, thin films, fibers, pultruded materials, and smart materials having a superior combination of properties.

Interrelating the many different aspects of nanoscience vital to developing new material systems, this book is organized into three parts that cover the major areas of focus: synthesis, manufacturing techniques, and modeling. The book defines functional materials and discusses techniques designed to improve material properties, durability, multifunctionality, and adaptability. It also examines sensors and actuators fabricated from nanostructured microdevices for structural health and performance monitoring. Shifting its focus to nanomechanics and the modeling of nanoscale particles, the book discusses vibration properties, thin films, and pulse laser deposition, low cost manufacturing of ceramic composites, hybrid nanocomposites, and various types of nanotubes. The book combines atomistic modeling with molecular dynamics simulations to clarify design considerations and discusses coupling between atomistic models and classical continuum mechanics models. The authors also advocate the current and potential development of commercial applications, such as nanocoatings to create “artificial skin” and functionalized nanotubes used to enhance the properties of composite materials.

Nanoengineering of Structural, Functional, and Smart Materials provides an overview of current trends and cutting-edge research in the area of nanoengineered materials. It offers new directions for the production of functionally tailored materials that can self-monitor their health and provide enduring performance.
