Yes, air plants do give off oxygen. Like all plants, air plants (also known as Tillandsias) use photosynthesis to capture carbon dioxide and release oxygen into the atmosphere. During photosynthesis, air plants absorb carbon dioxide from the air and convert it into oxygen, which they then release back into the surrounding environment. This process occurs throughout the day, allowing air plants to continuously produce oxygen. In fact, air plants are particularly beneficial for bedrooms because they have the unique ability to photosynthesize at night. While you sleep, air plants continue to emit fresh oxygen, improving the air quality in your bedroom. This can have several positive effects on your well-being, including reducing stress, lowering blood pressure, and improving focus. So, having air plants in your bedroom can not only enhance the aesthetic appeal but also promote a healthier living environment.
