Have you ever woken up in a stuffy bedroom or left a meeting with a headache, even though the room temperature felt comfortable? Often, the cause isn’t heat—it’s a buildup of carbon dioxide (CO₂) from people breathing in a space with limited fresh air. While outdoor CO₂ levels are typically around 400 ppm, indoor levels can rise much higher in tightly sealed homes, schools, and offices. Although these levels are not usually dangerous, CO₂ is an important indicator of ventilation and indoor air quality. Monitoring CO₂ can help you know when it’s time to bring in more fresh air.

August is Autoinflammatory Awareness Month, reminding us that early recognition matters. Persistent or recurring symptoms such as unexplained fevers, joint pain, fatigue, rashes, or ongoing inflammation should never be ignored. While these symptoms may have many causes, they can sometimes indicate a rare autoinflammatory disease. Your pharmacist can help review medications, discuss symptoms, answer questions, and recommend when to seek medical assessment. Early diagnosis and appropriate treatment can improve long term health and quality of life.
