The most helpful things you can do for someone who’s sick are simple: keep them hydrated, let them rest without guilt, and make their environment comfortable. Most upper respiratory infections and stomach bugs resolve at home with basic supportive care, so your role as a caregiver is less about fixing the illness and more about removing obstacles to recovery.
Hydration Matters More Than Food
Staying hydrated is one of the most important parts of the body’s recovery process, especially when fever, vomiting, or diarrhea are draining fluids faster than usual. Water is a fine starting point, but if the person has been vomiting or has diarrhea, plain water alone won’t replace the sodium and potassium they’re losing. Oral rehydration solutions, available at any pharmacy, are specifically formulated to match what the body needs. They work better than common household drinks like apple juice, soda, or sports drinks, which tend to be too high in sugar and too low in sodium to properly rehydrate someone.
If the sick person won’t drink a rehydration solution (they don’t taste great), diluting apple juice 1:1 with water is a reasonable backup. A Canadian clinical trial in young children with mild gastroenteritis found that this diluted apple juice actually led to less treatment failure than a standard rehydration solution, likely because kids were willing to drink more of it. The same logic applies to adults: the best fluid is the one they’ll actually sip consistently. Offer small, frequent amounts rather than a full glass, especially if nausea is an issue. Warm broth, herbal tea, and popsicles all count toward fluid intake.
Let Them Actually Rest
Rest sounds obvious, but most people are bad at it. They check email, keep up with chores, or feel guilty about doing nothing. As a caregiver, you can help by actively protecting their downtime. Take over responsibilities they’d normally handle. Keep the house quiet during naps. Bring things to them so they don’t have to get up.
Rest isn’t just about comfort. Sleep is when the immune system does its heaviest work, ramping up the signaling molecules that coordinate the body’s defense against infection. Cutting sleep short or staying mentally wired slows that process down. If the person you’re caring for says they feel guilty about sleeping all day, remind them that rest is genuinely the fastest route to feeling normal again.
Make the Room Work for Them
Small environmental adjustments can make a noticeable difference in how miserable someone feels. If they’re congested or have a sore throat, dry air makes everything worse. Running a humidifier in their room helps. The ideal indoor humidity range is 30% to 50%, which is enough to keep nasal passages and throat tissue from drying out without creating conditions for mold growth. If you don’t have a humidifier, a hot shower with the bathroom door closed accomplishes something similar for short-term relief.
Keep the room cool but not cold. Fresh air helps, so crack a window if the weather allows it. Have tissues, water, lip balm, a phone charger, and a trash can within arm’s reach. These small details signal that someone is paying attention, and that matters psychologically. Research consistently shows that people who feel supported during illness experience less distress and recover more effectively. Loneliness and feeling like a burden create real psychological strain that can work against healing.
What to Feed a Sick Person
If the person has a stomach bug, don’t push food. Let their appetite guide things. When they’re ready to eat, current guidelines from the National Institute of Diabetes and Digestive and Kidney Diseases say to go ahead and return to a normal diet. The old advice about sticking to bananas, rice, applesauce, and toast (the BRAT diet) has fallen out of favor. Research shows that following a restricted diet doesn’t actually help treat viral gastroenteritis. The body needs calories and nutrients to fight infection, so once food sounds appealing, offer whatever they’re willing to eat.
For a cold or flu, chicken soup is more than a comfort tradition. A study published in the journal Chest found that chicken soup significantly inhibited the migration of white blood cells involved in inflammation, and it did so in a dose-dependent way. Both the chicken and the vegetables in the soup individually showed this anti-inflammatory activity. That means it may genuinely reduce the congestion and discomfort caused by the body’s inflammatory response to a respiratory infection, on top of providing warm fluid and easy-to-digest nutrition.
Honey is another simple remedy worth offering. It can soothe a cough and coat an irritated throat. Just keep it away from children under one year old.
Managing Fever and Pain
Over-the-counter fever reducers and pain relievers can take the edge off the worst symptoms. For adults, the two main options are acetaminophen and ibuprofen, both widely available and effective. Follow the dosing instructions on the package carefully, and avoid combining products that contain the same active ingredient, which is easy to do accidentally with cold and flu combination medicines.
For children, dosing is weight-based and precision matters. Use the measuring syringe that comes with the liquid medication, never a kitchen spoon. Children under two should not receive acetaminophen without a doctor’s guidance. And for babies under 12 weeks, any fever at all is a reason to seek medical attention promptly, since it can signal a serious infection that needs evaluation.
Protecting Yourself and Others
Taking care of a sick person doesn’t help much if you get sick too. Regular cleaning of high-touch surfaces like doorknobs, light switches, faucet handles, and countertops removes most harmful viruses and bacteria. Soap and water or a household cleaner with detergent handles the job for routine cleaning. When someone in the house is actively ill, step up to actual disinfection using an EPA-registered disinfecting product or a properly diluted bleach solution.
Wash your hands after direct contact with the sick person, after handling their dishes or laundry, and after touching surfaces in their room. If possible, designate one bathroom for the sick person and keep towels, cups, and utensils separate.
When the Situation Is More Serious
Most common illnesses run their course in a few days to a week. But certain warning signs mean it’s time to call a doctor or head to urgent care. In adults, watch for breathing difficulty, chest pain lasting two minutes or more, confusion or unusual mental changes, persistent or severe vomiting and diarrhea, coughing or vomiting blood, and sudden severe dizziness or weakness.
In children, the red flags include bluish or grey skin, difficulty breathing, fever paired with neck stiffness or a change in alertness, increasing sleepiness that’s hard to rouse them from, severe or worsening pain, and seizures. If any of these develop, don’t wait to see if things improve on their own.
The Emotional Side of Being Sick
People who are sick often feel isolated, frustrated, or guilty about being a burden. Simply being present, checking in regularly, and showing patience goes further than you might think. Perceived social support has a measurable effect on recovery outcomes. It buffers against the depression and loneliness that can accompany even a short illness. You don’t need to hover constantly. A text, a visit with soup, picking up their kids from school, or just sitting in the room while they sleep all communicate the same thing: you’re not alone in this, and it’s okay to just be sick for a while.
