Heater Hazards: 5 Risks of Using Room Heaters Overnight

• Room heaters dry out the air, causing dry throat, itchy eyes, cracked lips, and irritated nasal passages, worsening conditions for those with asthma or allergies.
• Gas or kerosene heaters can emit carbon monoxide, a colorless, odorless, and potentially fatal gas, leading to headaches, dizziness, and nausea.
• Leaving heaters on overnight significantly increases fire risk, especially near flammable materials like curtains, bedding, or furniture.
• Overheating a room disrupts natural sleep cycles, causing restlessness, sweating, dehydration, and poor sleep quality.
• Continuous exposure to warm, dry air leads to overnight dehydration, resulting in morning headaches, dry mouth, and fatigue, particularly for children and the elderly.

Why It Matters: Using room heaters overnight poses serious health and safety risks, including fire, carbon monoxide poisoning, and dehydration.
