Wildfire Smoke? Your Body Needs More Water
Published Aug 2, 2025
During wildfire smoke exposure, staying hydrated helps your body clear fine particles and keeps airways moist. Dehydration worsens respiratory irritation and reduces filtration of pollutants. Drinking water regularly—even indoors—supports lung and cardiovascular health. When smoke levels are high, limit outdoor activity, use air filters, and hydrate frequently.
Hydration is key during wildfire smoke
When wildfires rage and smoke fills the air, it's crucial to protect your health. One simple yet vital step is staying hydrated. During wildfire smoke exposure, your body works harder to filter out fine particles, and adequate hydration becomes essential.
Water helps clear fine particles effectively
Hydration helps your body clear fine particles: Wildfire smoke contains tiny particles that can penetrate deep into your lungs. Staying hydrated helps your body's natural filtration systems work more efficiently to remove these particles.
Water keeps the respiratory system moist
Smoke can irritate and dry out your respiratory system. Drinking plenty of water helps keep your airways moist, reducing irritation and making it easier to breathe.
Dehydration reduces pollutant filtration, worsens irritation
When you're dehydrated, your body's ability to filter pollutants is reduced, potentially worsening respiratory symptoms and increasing the risk of health complications.
Hydration supports lungs and cardiovascular function
Adequate hydration is essential for overall health, including lung and cardiovascular function. When your body is well-hydrated, your lungs can function more efficiently, and your cardiovascular system can better transport oxygen throughout your body.
Practical steps for staying hydrated when smoky
What you can do to stay hydrated during wildfire smoke:
Sipping water throughout the day
Carry a water bottle with you and sip on it throughout the day, even when you're indoors.
Sugary drinks dehydrate, choose healthier options
Sugary drinks can dehydrate you, so stick to water, herbal teas, or diluted fruit juices.
Fruits and vegetables boost hydration levels
Fruits and vegetables like watermelon, cucumbers, and lettuce have high water content and can help you stay hydrated.
Reduce exposure to outdoor pollutants
When smoke levels are high, reduce your time outdoors to minimize exposure to pollutants.
Air purifiers remove fine particles indoors
If possible, use air purifiers with HEPA filters to remove fine particles from the air in your home.
Drink water when feeling thirsty
Pay attention to your thirst cues and drink water whenever you feel thirsty.
Hydration protects health during wildfire smoke
Staying hydrated is a simple yet effective way to protect your health during wildfire smoke exposure. By drinking water regularly, you can support your body's natural filtration systems, keep your airways moist, and reduce the risk of respiratory irritation. Remember to limit outdoor activity and use air filters when smoke levels are high. Your health is worth it.
