In one sentence, describe what the following article is about: A solid sleep schedule is good for anyone's sleep hygiene, and may help improve rest when you're pregnant. You will fall asleep and wake up easier if you get yourself on a sleep schedule. This means going to bed and waking up at roughly the same time each day, even weekends. When your body is on a regular sleep/wake cycle, you'll get tired at night and then energetic in the morning. Indigestion and nausea are common problems during pregnancy. You can exasperate these issues if you eat a heavy meal before bed. Try to stick to light snacks in the hours leading up to bedtime and don't eat within two to three hours of going to bed. It may help to schedule your big meals around lunch and dinner. Eating a big breakfast and a heavy lunch can stave off feelings of hunger at night. If you're feeling hungry or nauseous before bed, try having a few plain crackers. This can fill up your stomach and may prevent nighttime nausea. It is important to avoid eating within two to three hours of going to sleep because this can increase your chances of developing heartburn. When you're pregnant, you will urinate more due to the baby pressing down on your bladder. It's a good idea to cut back on liquids in the hours leading up to bedtime. Fluid intake throughout the day is important, so do not neglect water during daytime hours. Simply cut back on fluids close to bedtime. Caffeinated beverages, like teas and coffees, are a particularly big culprit in keeping you awake at night. As you should limit your caffeine intake when pregnant, it may be a good idea to cut out caffeinated beverages altogether during your pregnancy. If you're having trouble sleeping, try relaxation exercises. They can get your mind off of the stress of your pregnancy, as well as any bothersome physical symptoms. You can try a breathing exercise. Breathe in and out in slow, steady breaths. Focus on the air going in and out of your lungs. If there is any tension in your body, release that tension as you breathe. If your mind starts to wander, bring it back to the breath. Try guided imagery. Imagine a relaxing scenario, like a childhood home or an ideal vacation. Take a mental vacation to that place and try to let go of other thoughts. Imagine all aspects of your imagined getaway, including sight, sound, touch, smell, and taste. Where you're sleeping can have an impact on the quality of your sleep. If you're struggling to sleep while pregnant, evaluate your room and make any necessary changes. Try dimming the lights in your room before bed. This will alert your body that it's time to sleep. Make sure your room environment is relaxing. A room should be calm and peaceful. If your room is cluttered, this can make sleep difficult. Reduce any bothersome noise. If you live in a noisy neighborhood, use a fan or a noise machine to block out unwanted sounds. Keep your windows closed at night to reduce outside sound. Remove any blue light sources from your bedroom as well, such as TVs, computer screens, tablets, digital alarm clocks, and cell phones.
Summary: Get on a sleep schedule. Avoid heavy meals before bed. Limit liquid intake close to bedtime. Practice relaxation techniques. Make sure you have a solid sleep environment.

Problem: Article: If you're going to use a straightening or curling iron on your hair daily, it's important that to select one that's made with a material that will do the least damage to your hair. Inexpensive irons are usually made with metal that doesn't heat evenly so it can easily burn your hair. You'll pay more for an iron made with a higher quality material, but it will help minimize damage. Ceramic irons heat quickly and evenly, so they're not as likely to burn your hair. They also produce negative ions that help smooth cuticle and boost shine. Be sure to choose an iron that's made of ceramic and not just coated with it. A ceramic coating will eventually wear off over time. Tourmaline irons can produce 6 times the amount of negative ions that ceramic models do. As a result, you're left with smooth, shiny, healthy looking hair. Titanium irons are usually the most expensive, but they heat quickly and evenly. They're a particularly good option for thick or coarse hair. Many straightening and curling irons only have low, medium, and high heat settings. To keep your hair from getting damaged, you want to use the lowest heat possible to give you your desired style. That's why it's best to purchase an iron with digital heat controls that allow you to choose a specific temperature to heat to. In general, an iron that allows you to set the temperature between 175 degrees to 400 degrees Fahrenheit (80 degrees to 200 degrees Celsius) is sufficient for all hair types. The finer or thinner your hair is, the lower the temperature on your iron should be. Start at 175 degrees (80 degrees Celsius), and only raise the temperature if your hair isn't curling or straightening properly. No matter how thick or coarse your hair is, you should never set your iron to higher than 400 degrees Fahrenheit (200 degrees Celsius). The size of your straightening or curling iron can also affect how damaged your hair becomes. If you use a larger iron, you're less likely to need to go over the same section of hair twice to curl or straighten it properly. In general, a 1-inch (23-mm) curling or straightening iron is the most versatile for all hair types. If you have a shorter hair, you may want to use a smaller iron. If you have extremely thick or long hair, you may want to use a larger iron. When it comes to curling iron, it's also important to consider the hairstyle that you're going for. If you want tight ringlet curls, you'll want to use a smaller curling iron. If you want loose waves, you'll want to use a larger curling iron.
Summary:
Use an iron made of a high quality material. Opt for an iron that has adjustable temperature controls. Consider the size of your iron.
