Hydration helps, but it is not a detox
Water supports circulation, temperature control, digestion, and normal mucus production. It may make a dry throat feel more comfortable. It does not neutralize smoke or pull inhaled particles out of the lungs.
Why fire season raises hydration concerns
Wildfire smoke commonly overlaps with hot weather, outdoor work, evacuation, power outages, anxiety, and disrupted meals. Each can make it easier to forget fluids or increase fluid needs. Some medicines also affect heat tolerance or fluid balance.
Create a simple hydration system
- Keep filled bottles in the clean-air room and next to essential medications.
- Add water to go bags, vehicles, and pet kits.
- Offer drinks at meals and regular transition points during the day.
- Refill bottles when you check AQI or emergency alerts.
- Store safe water according to local emergency guidance.
Water versus electrolyte drinks
Water and regular meals are sufficient for many people. Electrolyte drinks may be useful after prolonged heavy sweating, vomiting, diarrhea, or clinician recommendation. Many sports drinks contain substantial sugar or sodium. People with diabetes, kidney disease, heart disease, or blood-pressure concerns should choose products carefully.
Do not force excessive water
More is not always better. Drinking extremely large amounts in a short period can dilute blood sodium and become dangerous. Drink steadily, respond to thirst, account for heat and activity, and seek personalized medical advice when needed.
Children
Offer water regularly and watch for dry mouth, reduced urination, unusual sleepiness, irritability, or refusal to drink. Infants have special needs. Do not give plain water to young infants or dilute formula unless a clinician instructs you to do so.
Older adults
Thirst can be less noticeable with age, and mobility or medication can make drinking harder. Make fluids easy to reach and check regularly on people who live alone. Confusion, weakness, dizziness, and reduced urination warrant attention.
Outdoor workers and caregivers
Plan work during cooler periods when possible, take shade and cleaner-air breaks, and reduce workload when heat or smoke is high. Employers must follow applicable heat and respiratory protection rules. An N95 makes breathing feel harder for some people and does not prevent heat illness.
Signs that need urgent action
Move a person to a cooler, cleaner place when they develop headache, dizziness, nausea, unusual weakness, heavy sweating, or muscle cramps. Confusion, fainting, inability to drink, very hot skin, or severe symptoms can indicate a medical emergency. Call 911.
Medical restrictions
People with heart failure, kidney disease, liver disease, endocrine conditions, or prescribed fluid limits should follow their clinician’s specific guidance.
