Problem: Article: To thrive, iguanas need access to certain types of light. Most importantly, iguanas need ultralight light that is in the UVB spectrum. Without this sort of light, your iguana could suffer from a deficiency of vitamin D, be unable to absorb calcium, and have other health problems.  Purchase UVB light bulbs that are specifically labelled for reptiles. Those made for reef tanks and plants don't provide enough UVB rays for your iguana. Make sure your lizard breed naturally adapted to this temperature. While UVB light should reach the entire habitat, make sure to place a light 12 to 18 inches (30 to 46 cm) above the iguana’s basking area. Since most climates are cooler than environments where iguanas thrive, you’ll need to install a source of heat in your iguana’s habitat. This is important, as your iguana will not thrive if it is too cold.  The coolest area of your iguana’s habitat should be between 75 and 80 degrees Fahrenheit (24 to 27 degrees Celsius). Keep the “basking area” between 95 and 100 degrees Fahrenheit (35 to 38 degrees Celsius). Place a thermostat in the middle and on the edge of the habitat. This way, you’ll be able to monitor the temperature in different parts of the habitat. Ultimately, this will help you make sure that the temperature and climate is right for your iguana. The basking area is an area of your iguana’s habitat where your iguana can enjoy heat and light. This area is fundamental to making your iguana happy. Without a basking area, your cage won’t simulate the iguana’s natural environment. Basking areas should have:  A large flat area for your iguana to lay. Direct light from a UVB light. A close proximity to a heat rock or another source of direct heat.
Summary: Provide your iguana with lots of light. Install a heat source for your iguana. Install thermostats in the habitat. Create a basking area.

INPUT ARTICLE: Article: In general, the quicker you move, the harder your body has to work, the more energy it uses, and the more calories you burn. For instance, a moderate-weight person can burn about 70 more calories per hour by increasing their walking speed from 3.5 to 4.5 mph (5.6 to 7.2 km/h). Thus, if you're interested in either burning calories or boosting your athletic potential, you'll want to move faster, rather than slower.  Most health resources define "brisk-paced" walking at about 3.0 mph (4.8 km/h) or greater — if you're unsure of where to start, this is a good benchmark pace.  Note that, in addition to providing better exercise, brisk-paced walking also decreases the amount of time you'll need to take to walk any given distance, freeing up more time for you to do other things with your day! As noted above, pedometers don't just measure steps while walking. Since they record any sort of rhythmic, repetitive, up-and-down motion, they're also useful for recording your steps during any number of other exercise activities. Keep in mind, however, that because your average stride length may differ for these activities, the distance reading you get may not be accurate. Below are just a few other activities for which a pedometer can measure your "steps":  Running Hiking Climbing stairs Jump roping Some pedometers even have options to measure your speed and distance on a bicycle. In general, people lose weight over time if they spend more calories per day than they take in from their food. If walking is your only form of daily exercise, you can use your pedometer to help you stay on track for your weight loss. Since your pedometer can tell you how far you've walked, you can use any online calorie calculator to find how many calories you've burnt based on the distance you walked. Add this to your basal metabolic rate (BMR), the number of calories you burn simply from living, and you'll know approximately how many calories you spent during the day. For instance, a 180 lb (81 kg) person who walks five miles over the course of three hours during the day burns about 720 calories. If this person's BMR is about 1,800 calories (typical for a young 6-foot tall male) they burnt about 2,520 calories during the day, so eating fewer calories than this would cause them to lose weight. Keeping your daily activity at a reasonable level isn't like a New Year's resolution that can be abandoned a few weeks after it's made — it should be a lifelong commitment. People who make a habit of exercising (with or without a pedometer) experience demonstrably longer, healthier lives on average than people who don't. However, these benefits are only the result of sustained, long-term fitness commitments, so try to stay motivated as you use your pedometer to make the task of consistently exercising much easier. Below are just a few ways to get "pumped up" for your fitness goals:  Remind yourself of your goals when you don't feel like exercising. Reward yourself when you achieve minor goals. Get a healthy amount of rest every day. Listen to exciting, captivating music. Watch inspirational movies. Take occasional breaks from your fitness routine. Tell other people about your goals.

SUMMARY: Walk at a brisk pace. Use movements besides walking. Use your pedometer to help you count calories. Keep yourself motivated for the long haul.

In one sentence, describe what the following article is about: Scarlet fever is most likely to affect children between the ages of 5 and 15. When someone within that age range develops symptoms of scarlet fever, you should be particularly cautious and take him or her to the doctor as soon as possible. If your child already suffers from an infection or any other disease that will weaken his or her immune system, he or she will be prone to bacterial infections like scarlet fever. The bacteria that causes scarlet fever lives in the nose and throat and is communicated by contact with liquids spread through coughing and sneezing. If you or your child touch something that someone has coughed or sneezed on, you are susceptible to contracting the disease that causes scarlet fever. This will is most likely to occur in crowded areas. Because young children are most susceptible to the disease, schools are a particularly common place to contract the disease. Your child should wash his or her hands frequently and refrain from sharing utensils, linens, towels, or other personal items with people. Individuals can be contagious even after they have ceased to be symptomatic. Anyone diagnosed with scarlet fever should stay home for at least 24 hours after beginning treatment with antibiotics.
Summary:
Be careful with children. Be mindful if your child has a weakened immune system. Be careful in crowded environments. Ensure that precautions are taken to limit the spread of the infection.
