What most people are concerned with is precipitation, which, in meteorology (the study of weather), is any form of water that falls onto the Earth's surface. Forms of precipitation include rain, hail, snow, and sleet. Low pressure is usually associated with humid air and in some cases, precipitation. A low pressure system is an air mass that has less dense air because its air is moister and/or warmer. Surrounding air draws inward toward the low system's center as the lighter air balloons upward, often causing clouds or precipitation because that moist air cools as it rises. You see this effect when air's invisible water vapor is forced to condense into droplets when it contacts the outside of a cold glass). But droplets won't form if the glass is only slightly cool ...thus, rising low pressure air will only produce rain if it gets up where the air is cool enough to condense the water vapor into droplets too heavy to be kept aloft by the rising air. (Clouds are simply water droplets that are small enough to be kept aloft). With very low pressure systems, storms are on the way (if they aren't there already). Clouds begin to form and move across the sky -thunderhead clouds forming when moist air is thrust very high. Sometimes tornadoes form when very high pressure air collides with very warm, moist low pressure air. Watch out for one on the TV news, online, or in your local newspaper. (Other sources may include magazines and books, but they may not be current.) Newspapers are a convenient method to find a weather map as they are cheap, reliable, and can be cut apart so you can carry them with you while learning to interpret the symbols. If possible, find a map covering a smaller area these can be easier to interpret. Focusing on a larger scale may be difficult for a beginner. On the map, notice the location, lines, arrows, patterns, colors, and numbers. Every sign counts and all are different.

About 35% of ganglion cysts don't cause any pain the only problem with them is that you might find them ugly. Luckily, about 38-58% of ganglion cysts actually go away on their own. If your ganglion isn't causing you any real trouble, you might just leave it as is and see if the situation resolves on its own. There are many products available over-the-counter that can help reduce swelling. The reduced swelling will ease pain temporarily, until the medication wears off and the swelling returns. However, because many ganglion cysts resolve on their own, managing pain in the short term is often a good way to wait it out. The three most common types of anti-inflammatory drugs available in pharmacies are: Ibuprofen (Advil, Motrin) Naproxen sodium (Aleve) Aspirin (Ascriptin, Bayer, Ecotrin) If you're feeling pain from your ganglion cyst, try applying cold to it. You can buy a gel pack from a pharmacy, or simply wrap some ice or a pack of frozen vegetables in a towel. Apply it directly to the area where you're feeling pain for 20 minutes at a time. Do this at least every day, up to once every three hours. Although the exact cause of ganglion cysts is still unknown, a leading theory suggests that they result from trauma to the joint (like a hard knock or crushing force). Another theory argues that they form when a joint is overused. In either case, limiting joint movement is known to relieve pain and speed up the healing process. Let the affected limb rest as much as possible. You might find it hard to remember that you're resting your joint, especially if the cyst is on the wrist. While it's easy to remember to stay off your feet, remembering to stop talking with your hands can be harder! In that case, you might consider applying a splint to the joint. It will both serve as a physical reminder to rest the joint and limit the joint's movement when you use the limb. Place a rigid object (like a piece of wood) along the joint you want to stabilize. You can also wrap the joint in something like a magazine or thick padding of towel or clothing. The splint should extend beyond the joint in both directions, so movement is as limited as possible. For example, a wrist splint should extend from the forearm, past the wrist, and down to the hand. Tie the splint into place with whatever you have on hand a necktie, tape, a belt, etc. Don't tie the splint too tightly you shouldn't be cutting off blood flow. If your hands or feet start to tingle, loosen your splint. A ganglion is essentially a balloon of liquid, and when it presses up against a nerve, it can cause pain. To encourage the cyst to drain its liquid naturally, doctors often suggest massaging the area. You don't need to use any particular technique or seek professional massage therapy, though. Simply rub the ganglion gently, but frequently throughout the day. Over time, you should see an improvement in symptoms. Ganglion cysts are sometimes called "Bible bumps" because people try to get rid of them by smashing them with a heavy book like the Bible. While smashing the ganglion can temporarily get rid of it, there's a 22-64% chance that the cyst will return if you use this method. Furthermore, you can cause even more damage to the already damaged tissue around the ganglion, or even break a bone if you smash the book with too much force.

Most sunscreens on the market are chemical, which means that chemicals in their formula actually prevent sun from hitting the skin by absorbing the rays. Physical sunblock, however, works by creating a physical barrier between the skin and the sun. Because the makeup won't allow your skin to absorb chemical sunscreen, it won't be effective protection. Physical sunscreen can still work over your makeup to deflect the sun's rays. Physical sunblocks come in powders, creams, and sprays, so choose whichever will be easiest for you to apply. Because your makeup is already applied, a spray sunblock will be your best bet to avoid ruining it. To apply it properly, close your eyes and hold your breath. Press down on the nozzle, and apply it by spraying back and forth over your entire face. Spray more than you think you need, because spray sunscreen don't cover quite as well as creams and lotions. Don't touch your face at all while the spray dries. If you touch it, you risk rubbing it off in spots and compromising the sun protection. Another spray option is a makeup setting spray with SPF. Like the spray sunscreen, this shouldn't be used as your only form of sun protection, but it's great for touch-ups and to help keep your makeup in place throughout the day. Not only do makeup setting sprays with SPF protect your skin from the sun, they can actually mattify and moisturize your skin at the same time.
