Dr. Amee Daxini, Dermatologist
Is the sun coming in the way of your daily routine? Not only can the sun put a damper on all your everyday activities, it is also responsible for being harmful for your skin. Sun tanning causes dry skin - which can be handled with a little moisturiser. But the sun also breaks down the collagen in your skin (the protein holding skin together). This leads to wrinkles, delays healing, and increases scars.Did you know that you could eat your way across the battlefiled this summer?

Sunscreen Can Protect Your Skin Against Skin Cancer and Premature Aging

Dr. Amrendra kumar, Dermatologist
Sunscreen can protect your skin against skin cancer and premature aging. However, it is not as effective unless it's applied correctly. Follow these tips when applying sunscreen:Choose a sunscreen that has an SPF of 30 or higher, is water resistant, and provides broad-spectrum coverage, which means it protects you from UVA and UVB rays. Follow these helpful tips when selecting a sunscreen.Apply sunscreen generously before going outdoors. It takes approximately 15 minutes for your skin to absorb the sunscreen and protect you. If you wait until you are in the sun to apply sunscreen, your skin is unprotected and can burn.Use enough sunscreen. Most adults need at least one ounce of sunscreen, about the amount you can hold in your palm, to fully cover all exposed areas of your body. Rub the sunscreen thoroughly into your skin.Apply sunscreen to all bare skin. Remember your neck, face, ears, tops of your feet and legs. For hard‐to‐reach areas like your back, ask someone to help you or use a spray sunscreen. If you have thinning hair, either apply sunscreen to your scalp or wear a wide‐brimmed hat. To protect your lips, apply a lip balm with a SPF of at least 15.Reapply sunscreen at least every two hours to remain protected, or immediately after swimming or excessively sweating. People who get sunburned usually didn't use enough sunscreen, didn't reapply it after being in the sun, or used an expired product. Your skin is exposed to the sun's harmful UV rays every time you go outside, even on cloudy days and in the winter. So whether you are on vacation or taking a brisk fall walk in your neighborhood, remember to use sunscreen.

Sunscreens contain filters that reflect or absorb UV rays. There are two main types of sunscreens: Organic - Also called chemical sunscreens,organic sunscreens absorb UV radiation and convert it to a small amount of heat. This group of active ingredients is the most widely used in sunscreens. Organic sunscreens might contain avobenzone, cinoxate, octyl methoxycinnamate, octyl salicylate, oxybenzone.Inorganic - Also called physical sunscreens,inorganic sunscreens reflect and scatter UV radiation. Inorganic sunscreens might contain titanium dioxide or zinc oxide. Sunscreens also might contain Vitamins. Vitamin E can protect against UV-induced DNA damage.

Sun Screens - When? How? From Experts

Dr. Puneet Goyal, Dermatologist
Most of us know that sun exposure, even small amounts over time, can lead to brown spots, breakouts, wrinkles, and skin cancer. Yet, even when armed with this vital knowledge we continue to commit crimes against our skin by not following sun-smart rules. Before you exit this article thinking, “I don’t live in the Sunshine State,” I will forewarn you that sun-smart rules apply to everyone!Read and learn..When Should I Apply Sunscreen?Sunscreen should be worn 365 days a year – rain or shine. UVA rays can also penetrate glass, so if you’re working in an office all day and you’re near a window, you are still getting exposed to UVA rays. Sunscreen is especially important when exfoliating the face and body because those upper layers of dead skin cells do provide some level of protection. Without those layers, you’re exposing fresh, new cells to damaging rays.Did you know?There are two types of sunscreen: chemical and physical.Chemical-based sunscreens work by changing UV rays into heat, then releasing that heat from the skin. This type of sunscreen should be applied 15 minutes before sun exposure to ensure that the filters have time to absorb.Physical sunscreens, which are often referred to as physical blockers, work by sitting on top of the skin to deflect and scatter damaging UV rays away from the skin. These do not technically need to be applied before sun exposure, but Dr. puneet advises to apply them to the body before putting on a bathing suit and getting dressed so you don’t miss any areas close to your bathing suit (which is where a lot of sunburns occur.)Makeup? Moisturizer? What Order Do I Apply?Sunscreen should be applied after moisturizer and before makeup. You absolutely, positively cannot depend solely on the SPF in your makeup to adequately protect your skin from the sun. However, usingSPF makeup atop sunscreen is a good idea! If you’re wearing makeup and you need to reapply sunscreen, there are some great mineral-based powder sunscreens that you can dust on without disturbing your makeup.How Much Should I Apply?The general rule of thumb is a teaspoon for the face and a shot-glass sized amount for the entire body. To give you an idea, a family of four should use an entire bottle of sunscreen 60 ml over the course of the day at the beach or pool.Do dab the sunscreen on the skin because it creates a thicker layer of sunblock, which is more effective.Don’t rub it in until it disappears because this reduces the level of protection.Do SPF Numbers Really Make a Difference?There’s a nominal difference between 30 and 50. Higher SPF lends a false sense of security despite the fact that it really isn’t that more effective. For optimal sun protection, the key is reapplying often, not using a higher SPF, unless you’re going to be outside all day, then a higher SPF is better, but reapplication is still key.SPF 15 blocks 93 percent of UVB rays.SPF 30 blocks approximately 97 percent of UVB rays.SPF 50 blocks an estimated 98 percent of UVB rays.What does SPF even do?SPF only indicates a sunscreen’s protection against UVB rays.Broad spectrum sunscreen is essential for shielding the skin from UVA (aging) and UVB (burning) rays. Dr. Baumann recommends a sunscreen fortified with antioxidants, such as vitamin E, because sun exposure generates free radicals that damage the skin. Sunscreen without antioxidants does not protect against free radical damage. Use a topical vitamin C serum daily (and especially before sun exposure) to help neutralize free radicals.Can The Foods I Eat Help Protect Me?Foods with high levels of antioxidants are great for the body as a whole. While they may help the skin defend itself against free radicals and promote the skin’s natural repair, they are not a substitute for sunscreen.

The Dangers of Touch Screen Phones

Dr. Vishwas Virmani, Physiotherapist
Touch screen cell phones are no more or less dangerous than any other cell phone. The danger comes from the magnetic field generated by the high frequency (usually PCS - which is in the microwave range) carrier, and you get that by holding the phone close to your ear while talking. But the relative size (not to mention the strength) of the field generated by the electronics needed for the touchscreen is minimal compared to the carrier frequency, so before you are talking on the phone (i.e. using the touch screen), there is no danger. Some users of mobile handsets have reported feeling several unspecific symptoms during and after its use; ranging from burning and tingling sensations in the skin of the head and extremities, fatigue, sleep disturbances, dizziness, loss of mental attention, reaction times and memory retentiveness, headaches, malaise, tachycardia (heart palpitations), to disturbances of the digestive system. Reports have noted that all of these symptoms can also be attributed to stress and that current research cannot separate the symptoms from nocebo effectsAvoiding injuries from typing and tapping. The position of your wrist also affects the likelihood of injury from performing multi touch gestures on touchscreens. According to Alan Hedge, director of the Human Factors and Ergonomics Laboratory at Cornell University, the more you dorsiflex  your wrist, the greater the chance of injury. But, he adds, most gestures don't require too much force, so you're usually safe as long as you don't bend your wrist excessively or repeat gestures too rapidly.CAUSES..1. Cell phone use during pregnancy may cause behavioural problems2.Cell phone users had an increased risk of malignant gliomas3. Cell phone use was linked to a higher rate of acoustic neuromas 4. Tumors are more likely to occur on the side of the head that the cell handset is used. One hour of cell phone use per day significantly increases tumor risk after ten years or more.5. Increases Stress Levels. The high frequency of cell phone use can have negative effects on our stress levels. The constant ringing, vibrating alerts, and reminders can put a cell phone user on edge6. Sleep disturbances and symptoms of depression7. Responding to messages at rapid speed can cause pain and inflammation of your joints.8. Back pain is also common with increased cell phone use, especially if you hold the phone between your neck and shoulders as you multitask. "Long periods of cell phone use cause you to arch your neck and hold your body in a strange posture..9. Increases Risk Of Eye Vision Problems Staring at your mobile device can cause problems in your vision later in life. Screens on mobile devices tend to be smaller than computer screens, which means you are more likely to squint and strain your eyes while reading messages. PRECAUTIONS1. Use hands-free to decrease the radiation to the head2. Keep the mobile phone away from the body3. Do not use telephone in a car without an external antenna
