Hay its very hot (sobrang init talaga!) the sun is up so early and it remain so active even in the late afternoon!!! so here are some tips i research about SUN (ice is melting:)
Excess sun exposure can cause sunburn, skin damage, skin cancer (the most common form of cancer), cataracts, and heat stroke. Take the right precautions to avoid these hazards and enjoy the sun safely.
1. Select an appropriate sunscreen.
The most important thing to look for is SPF, which stands for "sun protection factor". This number describes how effective the sunscreen is. Look for at least SPF 30.
Look for both UVA and UVB coverage. This means that the sunscreen will block both kinds of damaging ultraviolet light.
Look for a PABA-free sunscreen. Para-aminobenzoic acid, or PABA, was used in sunscreens for a long time, but it can stain clothing and cause an allergic reaction in some people.
If you will be swimming or sweating, choose a waterproof sunscreen. No sunscreen is truly waterproof, so you should reapply the sunscreen frequently, according to package instructions.
Choose a sunscreen that suits you. Some daily sunscreens aren't as gooey or smelly as some of the heavy-duty outdoor sport formulations. Some sunscreens come in spray-on, roll-on, and stick formats. Some sunscreens come with built-in insect repellent. If you dislike wearing it so much that you don't, it will do you no good. Wearing sunscreen need not be unpleasant, so smell and try different sunscreen brands and styles to find the one(s) that are best suited for you.
The word "sunblock" is a misnomer. Sunscreen slows the effects of the sun on skin by absorbing, reflecting, and scattering UV rays, but it doesn't stop them.
Apply plenty of sunscreen.
Apply the sunscreen generously.
Start ahead of time. Ideally, begin applying sunscreen at least a half hour before you go out.
Use more than you think you need. Most people do not use enough sunscreen, stopping at somewhere between one fourth and one half the quantity applied to test sunscreens.
Don't just grease it on. Put a little on and rub it in. Then do it again and again, until you have a deep, penetrating layer of sunscreen. Do it right and you won't notice it at all and it will truly protect.
Don't miss a spot!
Be thorough. Put it on the most vulnerable areas: the entire face and forehead, especially the nose and tips of ears, back of the neck, backs of knees, and arms. Make sure to cover all skin that will be exposed. Don't forget the tops of feet, if you're wearing sandals. Have a friend help with hard-to-reach spots like backs and shoulders.
Keep your sunscreen relatively fresh. Expired sunscreen may not be as effective as recently-purchased sunscreen, but in general, any sunscreen is better than no sunscreen. If there's no expiration date, try it and see if it still works, or replace anything older than about three years.
Applying one SPF 15 sunscreen and another SPF 20 sunscreen may give you slightly better coverage, but it does not add up to SPF 35.
A wide-brimmed hat. Cover up.
* Wear a hat with at least a 3-inch (8 cm) brim all around. A hat will also help to keep you cool. Baseball caps leave the ears and neck exposed, so they're not the best choice for sun protection. A hat will also help to protect your eyes from glare.
* Wear light-colored, loose fitting clothing. It will keep you cooler and help prevent sunburn by reflecting the sunlight. Be aware, though, that clothing may not block sunlight completely. In fact, an ordinary t-shirt may only be the equivalent of SPF 5. Look for clothing designed to block sun, even up to SPF 50, if you spend a lot of time outdoors.
They do more than look cool.
Wear sunglasses. Choose sunglasses that block UV light and wrap around to block light from the side, too. If you're not sure whether your old sunglasses adequately block UV, ask an optometrist to have them checked. Long term exposure to UV light can lead to cataracts. Wear sunglasses in conjunction with a hat.
Drink plenty of water.
Stay hydrated. Water is the best choice. If you'll be exercising heavily, a sports drink can help to replace electrolytes. Drink in proportion to how much you perspire, but remember that too much too quickly can harm you. It's best to take frequent, moderate portions. Too much sugar, as in soda, can undermine the benefits of the liquid, and alcohol can dehydrate you outright.
Relax in the shade.
Stay out of the sun. Especially between 10am and 4pm, stay out of the sun as much as possible. Finding a spot in the shade, carrying an umbrella or parasol, and scheduling outdoor activities to avoid those hours can help to minimize exposure.
7. Limit your total time in the sun.
A one-armed "trucker's tan".
Roll up car windows and run the air conditioning rather than dangling your arm out the window. Glass blocks UV light reasonably well.
9. Keep cool. If you have heavy physical activity to perform outside, try to do it in the morning or evening, not the heat of midday. Choose a shady spot to sit. Sip a cool drink. Take a swim.
