Chemotherapy is tough, but there are practical, evidence-based strategies that can meaningfully reduce its worst side effects. From managing nausea and fatigue to protecting your nerves and mouth, most of what makes chemo harder than it needs to be is preventable or at least manageable with the right preparation.
Staying Ahead of Nausea
Nausea is the side effect most people dread, but modern anti-nausea medications are highly effective when taken on schedule. The key is prevention, not reaction. Your oncology team will prescribe anti-nausea drugs tailored to how likely your specific chemo regimen is to cause vomiting. For stronger regimens, you’ll typically receive a combination of medications that block nausea signals through different pathways in your brain and gut. Take these exactly as prescribed, even if you feel fine, because it’s far easier to prevent nausea than to stop it once it starts.
What you eat matters too. Smaller, more frequent meals are easier to keep down than three large ones. Avoid spicy, fatty, or heavily salted foods, and try to reduce strong cooking smells, which can trigger nausea before you even sit down. Taking your anti-nausea medication before meals lets it kick in while you’re eating. Ginger candies and lemon drops can also help settle a queasy stomach between meals.
Some people develop what’s called anticipatory nausea, where anxiety about treatment triggers nausea before the drugs even enter your body. If this happens, your doctor can prescribe a short-acting anti-anxiety medication to take before sessions. Relaxation techniques (more on those below) can also help break the cycle.
Exercise Fights Fatigue Better Than Rest
It sounds counterintuitive, but resting more doesn’t fix chemo fatigue. In fact, moderate exercise is one of the only interventions proven to reduce it. An international panel of exercise scientists found that 30 minutes of moderate-intensity aerobic activity three times a week significantly lowers cancer-related fatigue, both during and after treatment. Adding two sessions per week of resistance training (think light weights or resistance bands, about two sets of 12 to 15 repetitions) provides additional benefit.
The intensity matters. Low-intensity exercise, like very slow walking, doesn’t appear to move the needle much. You want moderate effort: enough to raise your heart rate and breathing, but you should still be able to hold a conversation. A brisk walk, a bike ride, or a water aerobics class all qualify. Programs lasting at least 12 weeks show the strongest results, and sessions longer than 30 minutes may offer additional relief. Going beyond 150 minutes per week, however, doesn’t seem to add further benefit.
Start where you are. On bad days, even 10 minutes counts. The goal is consistency over intensity, and your capacity will fluctuate from week to week.
Protecting Your Hands and Feet From Nerve Damage
Certain chemo drugs, particularly taxanes like paclitaxel, can damage the nerves in your fingers and toes, causing numbness, tingling, and pain that sometimes lasts months or years after treatment ends. One surprisingly simple prevention method is cooling your hands and feet during infusions.
Frozen gloves and socks (stored at around negative 20 to negative 30 degrees Celsius) are worn starting 15 to 30 minutes before the infusion begins and kept on for 15 to 30 minutes after it ends. The cold constricts blood vessels in your extremities, reducing how much of the drug reaches those vulnerable peripheral nerves. Studies show this approach significantly lowers the incidence and severity of nerve damage. In one study of paclitaxel patients, cryotherapy reduced grade 2 or higher neuropathy to a statistically significant degree. Another found that patients using cooling were able to complete more of their planned treatment cycles without dose reductions.
The gloves and socks need to be swapped out roughly every 15 minutes to maintain effective cooling. The experience is uncomfortable (cold hands and feet for a couple of hours), but about 65% of patients in one large study found it reasonably tolerable, and only about 4% stopped due to discomfort. Common complaints include headache (about 19% of users) and cold intolerance (around 6%). Ask your infusion center whether they offer frozen gloves and socks, or whether you can bring your own.
Scalp Cooling to Reduce Hair Loss
Cold cap therapy works on a similar principle to frozen gloves: cooling the scalp reduces blood flow, limiting how much chemo drug reaches hair follicles. A multi-center study of breast cancer patients using the Paxman scalp cooling system found that 81% retained most of their hair (classified as no hair loss or only mild thinning). About 71% of participants experienced no adverse events from the cooling, and the most common complaint was headache (19%).
Scalp cooling requires wearing a tight-fitting chilled cap before, during, and after each infusion, which adds time to your appointments. It doesn’t work equally well with all chemo regimens, and availability varies by infusion center. Some patients rent portable cold cap systems to bring with them. The cost can be significant, so check whether your insurance covers it or whether your center offers it as part of treatment.
Keeping Your Mouth Healthy
Mouth sores (oral mucositis) are a common and painful side effect that can make eating miserable. Prevention starts with gentle oral hygiene. Rinse your mouth several times a day with a simple solution: one teaspoon of salt or one teaspoon of baking soda dissolved in eight ounces of warm water. Avoid commercial mouthwashes that contain alcohol, which can dry out and irritate already-sensitive tissue.
If sores develop, stick to soft, bland foods and avoid anything spicy, crunchy, or acidic. Citrus juice and tomato-based sauces are common offenders. Keep lip balm handy, since chemo can also cause severely chapped lips. Hard candy helps with dry mouth, another frequent complaint during treatment.
Hydration Protects Your Kidneys
Chemo drugs are processed through your kidneys and liver, and staying well-hydrated helps your body flush them out more efficiently. UCSF Health recommends a minimum of 8 to 10 eight-ounce glasses of water per day during treatment, which works out to roughly 2 to 2.5 quarts. This isn’t just a general wellness suggestion: adequate hydration reduces the risk of kidney damage from certain drugs and helps prevent the headaches that commonly accompany infusions.
Water is ideal, but other fluids count too. If plain water is unappealing (common when your taste buds are affected), try adding a slice of cucumber or a splash of juice. Popsicles and broth also contribute to your daily total.
Food Safety When Your Immune System Is Low
Chemo suppresses your white blood cell count, leaving you more vulnerable to infections, including those from food. During periods when your counts are at their lowest (typically 7 to 14 days after an infusion), food safety becomes genuinely important.
The core rules: cook all meat, fish, poultry, and eggs until well done. Avoid unpasteurized dairy products. Wash all fruits and vegetables thoroughly, and peel anything with an edible skin, like apples or cucumbers. Don’t eat refrigerated leftovers that are more than three days old. Keep cold foods below 40°F and hot foods above 140°F. Wash your hands before, during, and after food preparation, and don’t share food or utensils with others. Only drink water that has been filtered, distilled, or boiled for at least one minute.
Managing Anxiety During Infusions
Sitting in a chair while medication drips into your body for hours can produce real anxiety, especially after the first few sessions when you know what’s coming. Two techniques with strong support are progressive muscle relaxation and slow rhythmic breathing.
For progressive muscle relaxation, close your eyes and work through each major muscle group from your head down to your feet. Tense each group for a few seconds, then release. Pay attention to how the relaxed muscle feels compared to the tensed one. The whole process takes about 10 to 15 minutes and can noticeably lower tension.
For slow breathing, aim for about 9 to 12 breaths per minute. A simple way to maintain the rhythm is to silently count “in, one, two; out, one, two.” Breathe deeply enough to raise your belly, not just your chest. Even 10 minutes of this can shift your nervous system toward calm. Guided imagery, where you close your eyes and mentally place yourself somewhere peaceful and specific, is another option that many patients find effective during the infusion itself.
Packing for Infusion Day
A well-packed bag makes long infusion sessions significantly more bearable. Wear comfortable, loose clothing. If you have a port, a V-neck shirt keeps it accessible without awkward adjustments. Bring closed-toe shoes or slippers with a hard sole, plus warm socks, since infusion rooms tend to run cold.
Beyond clothing, the essentials include a warm blanket (infusion centers sometimes provide thin ones, but your own is better), a water bottle, and snacks you can tolerate. A laptop or tablet with a charger gives you entertainment options for hours at a stretch. Headphones are valuable whether you’re listening to music, watching a show, or just blocking out the hum of infusion pumps. Books, puzzles, a journal, and hard candy for dry mouth round out what experienced patients consistently recommend bringing along.
Planning your infusion days to fall before a rest day (a weekend, or a day off work) gives your body time to recover from the acute effects before you need to be functional again. Many patients find that the first 48 to 72 hours after an infusion are the hardest, and having nothing scheduled during that window makes a real difference.
