Do you have a headache?

Have you ever felt sleepy or inattentive in a meeting after lunch? Do you feel like you'll barely make it through the rest of the day before heading into the breakroom for another cup of coffee or an energy drink? This may have less to do with the effects of a full stomach and more to do with CO2 levels.

If you find yourself constantly weary, nauseated, or suffering from chronic headaches or body pain, you should examine the CO2 levels in your workplace or home.

Practical measures to improve CO2 levels indoors:

• Allow airflow by opening a nearby window or doors.

• Irritating and polluting substances such as aerosols, fragrances, and plugins should be avoided.

• Bring live plants into your office or home.

• Take frequent breaks by going outside for some fresh air.

• HVAC systems should be repaired or upgraded.

• Purchase air purifiers to lower the amount of particle matter and pollutants in the air.
