If you or a loved one has experienced pressure ulcers or bedsores, you may already know a little about pressure injuries. Painful wounds caused by constant pressure on the skin cut off blood flow over time, the tissue underneath starts to break down. For families supporting a loved one who spends a lot of time in bed or in a wheelchair, understanding pressure injuries early can make a real difference.
Prevention is key, once one forms, it can take weeks or months to heal, and some become serious enough to require hospitalization. The good news is that most pressure injuries are preventable with consistent daily care. Here’s what families and caregivers should know.
What Causes Pressure Injuries
Pressure injuries happen because skin and tissue can only handle so much sustained pressure before circulation is cut off. Normally, your body sends nerve signals that make you shift positions without even thinking about it. When someone has limited mobility, sensation loss, or spends long stretches in one position, those natural signals don’t lead to movement the way they should, and the skin pays the price.
Daily Habits That Help Prevent Pressure Injuries
A few consistent habits go a long way toward preventing pressure injuries:
Reposition often. In bed, shifting positions every two hours will redistribute weight and relieve pressure. In a chair, small weight shifts every 15 to 30 minutes help release from the same spot.
Add padding where it counts. Pillows or wedges between the knees, ankles, and elbows reduce friction and pressure between bony areas.
Float the heels. Keeping heels off the mattress entirely is one of the simplest ways to protect a high-risk area.
Keep skin clean and balanced. Skin that’s too dry or too moist breaks down more easily, so gentle cleansing and proper moisture care both matter.
Stay hydrated. Drinking water throughout the day supports skin health from the inside out.
Checking the Skin Every Day
A daily skin check is one of the most important habits for catching pressure injuries early. Look for redness that doesn’t fade, blisters, or discoloration that looks purple or bluish. Don’t forget to check under braces, oxygen tubing, and casts, since these can rub or press on skin in ways that aren’t always obvious. Fingernails and toenails are worth a glance too.
The areas with the highest risk are usually the spots where skin sits directly over bone: the heels, sacrum, tailbone, elbows, back of the head, ankles, knees, and hip area. If skin ever breaks open, it’s time to call the care team right away rather than waiting to see if it improves on its own.
Nutrition and Lifestyle Play a Role
Adequate hydration and a diet that supports tissue health can help reduce risk, especially for individuals managing limited mobility long term. For a deeper look at how nutrition supports skin integrity and overall health, according to the American Institute for Research partner Model Systems Knowledge Translation Center’s guide on nutrition is a helpful, evidence-based resource families can reference.
A few other everyday factors matter too. Limiting caffeine can support better hydration overall. Avoiding heavy items in back pockets removes unnecessary pressure points. Shoes that run one to two sizes larger help accommodate swelling. Sun exposure should be limited as well, since certain medications can make skin more sensitive to burning. And staying as active as possible, along with avoiding smoking, supports the circulation that skin depends on to stay healthy.
Why This Matters
Pressure injuries aren’t just uncomfortable. In more advanced cases, they can lead to infection and other serious complications. That’s exactly why prevention is emphasized so heavily, both at home and in skilled nursing settings. Before a resident leaves the hospital, nurses and therapists typically walk through pressure relief techniques tailored to that person’s specific needs, since the right approach for preventing pressure injuries can vary quite a bit from one person to the next.

How often should someone reposition to prevent pressure injuries?
Every two hours in bed is a common guideline, with more frequent weight shifts, roughly every 15 to 30 minutes, recommended for those seated in a chair.
What are the earliest signs of a pressure injury?
Persistent redness, discoloration, or a bluish or purple tint to the skin are usually the first warning signs, especially over bony areas.
Are pressure injuries really preventable?
In many cases, yes. Consistent repositioning, skin checks, and good hydration can significantly lower the risk of pressure injuries.
When should a doctor be called?
Any time skin breaks open or shows signs of worsening, it's best to contact the care team promptly rather than waiting.
