Q: Many office and personal desk chairs have adjustable backs, seats, and even lumbar support. Since the type of chair that you use will vary, try to keep the following criteria in mind: Your upper legs should be flat against the bottom of the chair. Your lower legs should form a 90 degree angle at the knees. Your feet should be at a flat 90 degree angle to your lower legs. Your back should be at between 100 and 135 degrees in relation to your legs (if possible). Your arms should be tucked near your sides. Your shoulders and neck should be relaxed. Your eyes should be able to view the screen comfortably without having to stretch, crane, or strain your neck or your eyes. If your chair has lumbar support, a customized cushion, adjustable arm rests, or any other type of specialized support, adjust it as needed. It's okay to remove things like arm rests and cushions if they interfere with your posture. Your keyboard should be directly in front of your body; don't twist or bend your body in order to reach your computer. Ideally, your computer's screen will be at least one arm length away from you. You may be tempted to slouch your neck, thus bringing your chin close to your chest; this will lead to neck, shoulder, and back pain, so keep your head up even if you have to look down at the screen. One possible fix for this is adjusting your monitor's height so that it sits at your actual eye height. It's easy to take shallow breaths when sitting down, but doing so will eventually lead to other problems. Make sure to take deep breaths oftenespecially if you find yourself experiencing a headache or lightheadednessand try to hold a few deep breaths in once every hour or so. Shallow breaths can cause you to adjust unconsciously your posture, while deep, diaphragm-level breaths will help you center your posture. If you have enough space on your desk to accommodate your documents, phone, and other accessories, make sure that they're arranged around the computer; your computer should be the center item on your desk. Some computer trays have different levels for different items (e.g., documents, keyboard, writing implements, etc.). If you do not have a fully adjustable keyboard tray, you may need to adjust your workstation height and the height of your chair, or use a seat cushion to get in a comfortable position. Studies have shown that constant sitting is very damaging to your health. Try walking around for a couple minutes, standing and doing stretchesanything to break up a full day of sitting is good for you! Take short 1-2 minute stand, stretch, and/or walk breaks every 20-30 minutes. If you have lunch breaks or meetings, try to keep them as far away from your computer as possible, and stand when you're able. While your eyes may not seem like they have much to do with your back and posture, eye fatigue can cause you to slouch, lean in closer to your computer, and more. Simply looking away from your screen for a few seconds every 30 minutes or so should do the trick. A good way to prevent eye fatigue is by using the 20/20/20 rule: every 20 minutes, look at something at least 20 feet (6.1m) away for 20 seconds. You can purchase blue light filter glasses (e.g., computer glasses), which will both decrease your eye strain and improve your sleep at night, for as little a $10. Aside from your eyes, your hands are the most active part of your body when you're using a computer. You can prevent carpal tunnel by pushing on the joints of one hand while bending the fingers back, as well as by using squeezing resistance movements (e.g., squeezing a tennis ball).
A: Sit using ideal posture. Adjust any support for your chair. Sit close to your keyboard. Keep your head elevated. Take deep breaths. Arrange any documents and items around to your computer. Take small breaks during your workday to release some of that muscle tension. Avoid eye fatigue. Exercise your hands.

Q: Wash and dry your face as usual, either over a sink or in the shower, and use warm to hot water to open your pores. It might be a good idea to use a gentle facial cleanser before applying this mask, especially if you have sensitive skin. Lemon juice can be harsh, and stressing your skin with too much abrasive material can do more harm than good. When your face is clean and dry, use your fingers to apply the lemon-honey mask all over the skin. Work carefully to avoid the eye area. This mask can cause stinging and irritation to the eyes. If you accidentally get it into your eyes, flush it out immediately with cool to lukewarm water for a full minute, or until the stinging stops. The mask can also be quite sticky, so it's a good idea to make sure hair is pulled back and out of the way before application. The wait time is important; if you rinse the mask off too quickly, the honey and lemon won't have enough time to do their work. Of course, if your skin starts to burn, itch, or otherwise feel uncomfortable, you should rinse the mask off immediately. It's possible that your skin is having a negative reaction to the mask if you experience these symptoms. When the waiting period ends, rinse the mask off your face using warm water. After finishing the warm water rinse, do a second rinse with cool water to close your pores. You can also wipe away the mask with a warm, slightly damp wash cloth. The wash cloth acts as a physical exfoliator. Use gentle patting motions when using this trick, however, to avoid irritating your skin. The exact frequency with which you apply the mask may vary depending on how sensitive or oily your skin is, but a good average is about once a week, either in the morning or evening. You can try applying the mask two to three times a week if you have notably oily or acne-prone skin, but cut back if you notice any redness, irritation, or increased amounts of acne.
A:
Wash your face. Apply the mask over your face. Allow the mask to sit for 15 to 20 minutes. Rinse with warm water. Repeat weekly, if desired.
