INPUT ARTICLE: Article: The most important aspect of copper sink care is to steer clear of harsh chemicals and abrasive cleaners or scrubbers. Don't use bleach, lime or rust removers, or ammonia-based cleaners in or around your sink. Stay away from abrasive powdered cleaners like Comet. Never use scouring pads, steel wool, or any other hard scrubbing pad. Acidic foods and liquids are harmful to all copper surfaces. Don't let things like tomato sauce or lemon juice sit in your sink, and keep the water running when dealing with any acidic items. Toothpaste can also discolor copper, so rinse away toothpaste residue after brushing if your bathroom sink is copper. Putting cookware away as soon as possible will keep any copper sink in the best condition, whether vintage or polished. Dirty pots and pans might contain acidic ingredients that can discolor both patina and polish. Pots and pans left to dry in the sink can shift positions and potentially leave a dent in a shiny copper surface. If you have hard water, it's especially important to dry your sink every time you use it. Mineral deposits can be unsightly on both polished copper and surfaces with a patina. The most accurate ways to determine if you have hard water are to ask your water company or to use a home test kit. You can purchase a kit online or at a store that sells pools, or you can contact a water softener company and ask if they offer free tests.

SUMMARY: Avoid using harsh chemicals or abrasive scrubbers. Avoid letting acidic foods or toothpaste sit in a copper sink. Avoid leaving pots and pans in your sink for too long. Dry your sink after each use to prevent hard water deposits.

In one sentence, describe what the following article is about: Regular exercise can reduce blood pressure and also reduce blood sugar, "bad" fats, and cholesterol, as well as help you reduce excess weight. All of these are factors that have been indirectly linked to the hardening of arteries. Regular exercise will also help you to strengthen your heart muscle and improve your overall health. You should aim for at least 2 hours and 30 minutes of moderate aerobic exercise each week or 1 hour and 15 minutes of intense exercise. The more active you are, the more you will benefit. Participate in aerobic exercise for at least ten minutes at a time spread throughout the week. Plan to do exercises that will elevate your heart rate and oxygen use but that you can sustain at low or moderate intensity for an extended period. Some exercises that fit this recommendation are walking, running, swimming, cycling, jumping rope, or rowing. Experts also recommend two to three 20-30 minute weight training sessions every week, in addition to cardio. Weight training builds lean muscle mass and is part of a healthy workout regimen. The Mayo Clinic suggests that you go at your own pace. If you are not currently exercising, start gradually by walking and performing other low-impact activities that you feel comfortable doing. Give yourself plenty of time to warm up and then gently increase the intensity. As your stamina increases, gradually lengthen the amount of time that you exercise to 30 to 60 minutes each session. Listen to your body, as well and stop if you feel pain, nausea, dizziness, or shortness of breath. Plan your week in order to fit in exercise. If finding time is hard, try to work exercise into your daily routine. Walk to work or to run errands, for example, take the stairs rather than the elevator, or watch your favorite TV shows while on a treadmill. Exercise partners can hold you accountable and create a more social atmosphere. By joining a group such as aerobics, a sports league, or another structured program you may get more enjoyment out of exercise.
Summary: Start an exercise program. Go slowly at first. Create a routine.

INPUT ARTICLE: Article: Slowing down your breathing by exhaling for longer than you inhale and taking deep breaths has been shown to not only stimulate your vagus nerve, but also reduce anxiety and promote calmness. Aim to take 6 10-second breaths per minute for 5 minutes to increase vagal activity. Deeply breathe in with your diaphragm so that your stomach expands outward. Try breathing in for 5 seconds and then slowly exhaling for 5 seconds. If you're having trouble performing deep breathing exercises, try looking up helpful videos online or downloading an app that will guide you in your breathing. Studies have shown that regularly performing yoga increases the activity of your parasympathetic nervous system, which includes greater stimulation of your vagus nerve. For best results, perform at least 90 minutes of yoga each week consistently. If you're a beginner, start out with some relatively easy yoga poses, such as the cat pose, cow pose, bridge pose, and the aptly named easy pose. Similar slow exercises, such as tai chi and qi gong, have also been shown to have a stimulating effect on the vagus nerve. Don't try to do yoga that is overly difficult for you to do. Remember, yoga should be relaxing as well as physically engaging. Exercise that significantly increases your heart rate, such as jogging, walking, or weightlifting, has a number of positive effects on your mental health, including vagus nerve stimulation. Aim to perform this exercise at least every other day to receive consistent positive results. Try to engage in exercises that you enjoy doing; this will help ensure that you're able to do them consistently. Regular exercise also increases brain growth and can help reverse cognitive decline. . Progressive muscle relaxation is an effective way to reduce anxiety. Starting with your toes, squeeze the muscles in both feet to tense them, hold for 10 seconds, then release. Do this for each muscle group in your body until you reach the top of your head. Then, relax for as long as you like. Find a quiet, comfortable spot to perform a progressive muscle relaxation. Remember to breathe as you perform this exercise. Although your sympathetic nervous system will be initially heightened after being exposed to the cold, once your body becomes acclimated your parasympathetic nervous system will generate a response, including by stimulating the vagus nerve. Try splashing cold water on your face or ending your showers with 1 minute of cold water to increase vagal activity. Over time, you may find it helpful to take showers only using cold water. Simply spending some time underdressed in cold weather (e.g., wearing a t-shirt during a snowfall) can also stimulate your vagus nerve. For those suffering from epilepsy or from depression that doesn't respond to therapy or medication, there are devices (called programmable pulse generator devices) that doctors can implant under the skin that stimulate the vagus nerve with electrical impulses that may be particularly useful. Talk to your doctor to determine whether this type of device is right for you. This form of vagus nerve stimulation is generally considered safe for most people. Some side effects may include voice changes, throat pain, cough, headache, chest pain, or tingling on the skin. As of September 2018, noninvasive devices that stimulate the vagus nerve and that don't require surgery are available in Europe, but have not yet been made available in the United States.

SUMMARY:
Perform slow, deep breathing exercises. Do yoga for 90 minutes every week. Engage in moderate to intense exercise 4 times a week. Perform progressive muscle relaxation Expose your body to cold water, weather, or beverages. Undergo surgery to implant a device that stimulates your vagus nerve electrically.
