Wrinkle-causing UVA rays and burn-inducing UVB\'s can pose a serious risk to your health (and good looks). So what can you do?

The weather is warming up, the days are longer and there's more time to be outside doing all kinds of fun things!

But if you're going to be out in the sun, especially on a hot day, you need to stay safe. Let's find out how.

Don't Feel the Burn

Even though the sun is hot, it does cool things. It keeps us warm. It makes flowers and plants grow. It even gives us vitamin D so we can better absorb calcium into our bodies for strong bones.

It does all these things by sending down light, which includes invisible ultraviolet (say: ul-trah-VYE-uh-lit) rays. These are also called UV rays. Some ultraviolet rays pass through air and clouds and reach the skin. When your skin's been exposed to too many of these rays, you get what's known as a sunburn. Ouch!

Some people get a sunburn faster than others because of their coloring. If you have blond or red hair, light-colored skin, and light-colored eyes, you'll tend to get a sunburn more quickly than someone with dark eyes and skin. That's because you have less melanin (say: MEL-uh-nun). Melanin is a chemical in the skin that protects it from sun damage by reflecting and absorbing UV rays. People with darker skin have more melanin, but even if you have dark hair, dark eyes, or darker-toned skin, you can still get a sunburn. It will just take a little bit longer.

Sunburns look bad and feel worse. They can cause blisters on your skin. They can keep you inside feeling sore when everyone else is outside having fun. They increase your chance of getting wrinkly when you get older. And worst of all, they can lead to skin cancer when you are an adult. Because getting wrinkles and getting sick don't happen right away, they can seem like things that could never happen to you. But you still need to be careful.

Prime Time

You don't need to hide from the sun completely. But you should take these two steps:

1. Always wear sunscreen.

2. Take breaks from the sun often by going indoors or moving into the shade.

These steps are especially important between 10 a.m. (in the morning) and 4 p.m. (in the afternoon), when the sun's rays are strongest.

Use a sunscreen with an SPF rating of 30 or higher. Put on sunscreen 15 to 20 minutes before going out in the sun. The letters SPF stand for sun protection factor, and the number rating tells you how much longer you can stay in the sun without getting sunburned.

But this isn't always true, so reapply sunscreen at least every 2 hours, just to be safe. Do this more often if you've been swimming or sweating a lot - even if the sunscreen is waterproof. And remember that you can get sunburned more quickly when you're swimming or boating because the reflection from the water makes the sun's rays stronger.

Be sure to put sunscreen all over your body. This includes some places you might not think of, like the tops of your ears, the back of your neck, the part in your hair, your face, and the tops of your feet. You may need some help reaching the back of your body so ask your parents or friends to give you a hand. If you want to block the sun's rays, wear clothing that you can't see your hand through. You may still get burned through more sheer fabrics. Wear a baseball cap or other fun hat to block your face from the sun.

Don't forget that your eyes need protection from ultraviolet rays, too. Always wear sunglasses in the sun, and make sure they have a label saying that they block UV rays.

Drink Up!

Drinking water is an important part of staying healthy, especially when it's hot outside. When you're sweating, you lose water that your body needs to work properly. And if you're playing a sport or running around in the sun, you lose even more water, because you sweat that much more.

So drink up and don't wait until you're thirsty - drinking before you feel thirsty helps keep the water level in your body from dropping too low (dehydration) when it's hot or you're sweating a lot with exercise. If you forget and suddenly feel thirsty, start drinking then. There are lots of cool-looking water bottles around, so get one you really like, fill it up, and drink up!

Got That Hot Feeling?

If you're out in the hot sun or you're exercising on a hot day, it's easy to get heat exhaustion. Kids get heat exhaustion when their bodies can't cool themselves fast enough. A kid with heat exhaustion might feel overheated, tired, and weak.

Heat exhaustion can come on suddenly. A person may just collapse when playing soccer or tennis, for example. It can leave someone feeling really tired after it happens.

Heat stroke is a more serious heat-related illness and can cause someone to stop sweating; to have red, hot skin; and to have a high temperature. The person might become uncoordinated, confused, or even lose consciousness. It requires emergency medical attention.

Be sure to tell an adult if you're hot and you have a headache or feel dizzy or nauseated (like you're going to throw up). The grown-up will want to get you out of the sun, give you liquids to drink, and take you to a doctor, if necessary.

The good news is that the sun doesn't have to be your enemy if you wear your sunscreen, drink your water, and take breaks when you start to feel too hot. And don't forget your sunglasses. Not only do they protect your eyes from the sun, they make you look so cool!

So you know that the closest star to Earth is the sun right! And that this star is the centre of our solar system. This star is responsible for providing life on Earth. Pretty cool right! Below you will find more information and facts about our amazing star. The sun.

All other stars are made up of gases, and the sun is no different. The sun is a G2 Yellow dwarf star and is around 4.6 billion years old. The sun started to form and take shape at the time the solar system was also forming. You will know from reading up and learning about the solar system that all planets and other things in the solar system revolve around our star. Our star is very important in our neighbourhood.

The gases that make up the sun are Hydrogen and Helium, but mostly Hydrogen. When you look at the sun from Earth it's Yellow in colour, but in fact when you look more closely through a telescope the colour is more Orangey Red due to its extreme heat. The temperature of the sun is nearly 10,000 degrees, and the temperature at the sun's core is around about 27 million degrees. Let's just say that nobody will ever get near enough to the sun or its core. Hot Hot!!

Believe it or not, the sun actually has a surface, however its very different to the surface of the Earth, and not a surface that we will ever get near or set foot on, but a surface all the same.

Naturally the surface is extremely hot for a start. The surface also has a name. It's called the Photosphere. The surface consists of very large and very wide cells of gas. The cells can be as large as 1,000 miles across. The cells are constantly moving, so while the sun has a surface, it's very different to the surface of planets.

There are also other weird things that happen on the sun. Called phenomena. First off, there are sunspots on the sun. These are darker coloured areas on the sun that appear in different areas at different times when the magnetic field is blocked by the rising heat. Secondly, other phenomena called Prominence. Prominences are basically large bursts of gas that are arch shaped from the surface that is released into space.
# 1. The sun is a classified G2 Yellow Dwarf star.
# 2. Earth could fit into the sun over 1 million times.

# 3. The Sun's official name is called 'Sol'
