Article: Bad circulation causes swelling. Therefore, try to stay off your feet if you can. When you lay down, make sure that you lift your feet up. You want your feet to go up as far as you can raise them. You can place a stool under your feet if it will help you keep them up. Foot swelling after a tattoo is caused by your body storing excessive amounts of water. To keep this from happening, you should drink plenty of water. You want to drink enough so that your body will want to expel water instead of retaining it. Of course, you should not place ice directly on your tattoo. The best way to lessen swelling and keep your tattoo dry is to wrap ice in a piece of cloth and place it on your tattoo. Try doing this for thirty minutes to an hour every day you have swelling. You need to maintain proper circulation in order to keep swelling down. Therefore, when you are lying down, try to do some exercises. They don’t need to be intense, just regular. Stretching, for example, would be beneficial. Try lifting your legs and arms at intervals.
Question: What is a summary of what this article is about?
Elevate your feet. Drink water. Apply ice to swelling or bruising. Exercise.

Problem: Article: If you have multiple faucets, spigots, or appliances running while you test the flow rate, it will give you an inaccurate reading. Make sure all water-fed appliances and faucets are in the off position while you measure the water flow. Water-fed appliances include the dishwasher and laundry machine. These locations will give you the most accurate reading because it's closest to your main water supply. Water loses pressure as it travels through pipes and the water supply is usually located in the basement or bottom floor. Use a bathtub faucet or a spigot near the main water feed since other fixtures may have factory restrictions. Use a bucket that's exactly 1 gallon (3.8 L). You are finding gallons or liters per minute, and the size of the bucket needs to be exact. Turn on the spigot or faucet and use a watch or timer and count how many seconds it takes to fill up the bucket completely. Once you get the time, mark it down on a piece of paper.  The main water supply can usually be found in your basement, crawlspace, or next to your water heater. Sometimes the main water supply will be connected to the outside of your house or located in a covered box near the sidewalk. Dividing 60 by the number of seconds it took to fill up your bucket will give you your house’s gallons (liters) per minute or GPM (LPM). Most residential houses should maintain a flow of 6 gallons (23 L) per minute. This will allow larger appliances, like a washer machine or shower, to operate at a normal water pressure. For instance, if it took 30 seconds to fill up the bucket you'd calculate 60/30 = 2 gallons per minute. If your flow rate is higher than 6 GPM, it may mean that your water pressure is too high. Hire a plumber or handyman to install a water pressure regulator to your main water supply to regulate the flow of water. If your water pressure is too high, water may shoot out of the sides and crevices in your pipes or spigots and could cause premature failure in your faucets and appliances. If you have under 6 GPM it means that you may have low water pressure. Low pressure can be caused by blocked pipes, leaking pipes, or a water supply malfunction. A water booster can also sometimes be installed into to increase water pressure.
Summary: Turn off all faucets in your house. Find a spigot or faucet on the bottom floor or basement. Place a 1 gallon (3.8 L) bucket under the faucet. Fill the bucket and time it. Divide 60 by the number of seconds it took to fill up the bucket. Install a water pressure regulator for pressure over 6 GPM. Call your landlord or water company for pressure lower than 6 GPM.

When you’re first getting acclimated to working out outdoors, it’s best to start with roughly 15 minutes of moderate exercise at a time. As your conditioning improves, you can begin to add 2-3 minutes to each session. Take plenty of rest breaks and be careful not to try to do too much too soon.  Pay close attention to how you feel after each period of activity. If you detect that your performance is dropping off, play it safe and decrease your intensity or take longer breaks. It typically takes about two weeks for the average person to become heating acclimatized. Fill up on cold water before you set out to bike, hike or jog and plan for frequent hydration stops along the way. Keeping your tissues flushed with water is crucial if you’re going to be slogging it out in stifling conditions—elevated temperatures will cause you to sweat constantly, even when you’re not actively exerting yourself.  Dehydration can be deceptive. Replenish your fluid levels at regular intervals, whether you feel thirsty or not. Always carry a water bottle with you, or make sure there’s another available source of water nearby. Sports drinks replenish not only fluids, but also essential electrolytes which are needed to power your muscles through a workout. After your first couple of weeks in a new environment, crank up the duration of your activity to around an hour at a time. This will soon become easier, and you can begin spending even longer periods outdoors. If your goal is to acclimatize as quickly as possible, plan on building up to least two hours a day.  Once you’re able to comfortably stay out for two or more hours a day, you’ll begin to feel much more at ease in motion and at rest. Raise your tolerance by finding an area with some light shade or stripping off non-essential items of clothing rather than seeking refuge indoors. Monitor your heart rate and breathing patterns vigilantly and be ready to call it a day if they start getting out of control. Even if you’re an elite athlete, there will come a point when your body can no longer keep up with the demands of working out in the heat. At this point, your continued efforts can go from difficult to dangerous.  Listen to your body, not your exercise journal. Stop what you're doing and seek out a shady place to rest when you feel the heat getting to you, even if you haven't finished your session. Consider splitting your workouts up into multiple short sessions to reduce your risk of overheating.
