At FNP, we believe greenery isn't just about aesthetics, it's about wellbeing. The still presence of a plant can breathe life into a room, quite literally. Among the many wonders of nature, one of the most remarkable is a plant's ability to purify air and release oxygen. But did you know that some plants go above and beyond, offering this benefit even while you sleep? If you've ever wondered which plant provides oxygen 24 hours a day, keep reading. Nature has a few all-day breathers that work tirelessly to refresh your space.
Yes, there are 24-hour oxygen-giving plants that release oxygen during the night as well, making them the perfect companions for bedrooms, study nooks, or any indoor retreat. These bedroom plants that give oxygen at night are especially loved by those seeking a little more peace, calm, and cleaner air without depending on electronic purifiers.
Let's take a deeper look at the best plants for oxygen, those silent overachievers working around the clock to uplift your health and home.

Meet the Best Plants That Give Oxygen 24 Hours a Day
From sacred staples to sculptural succulents, these five indoor champions work tirelessly to purify your air and enhance your space.
- Snake Plant: The Standout Star - Also known as Sansevieria or Mother-in-Law's Tongue, the Snake Plant is among the most celebrated indoor oxygen plants that don't need sunlight. Its tall, sword-like leaves thrive in dim corners and fluorescents alike. What makes it a standout is its ability to release oxygen 24 hours a day, even during the night, a rare feat in the plant world. Low-maintenance, sculptural, and resilient, it's perfect for those of us who juggle too much and water too little. Add it to your bedroom, and you've got not just a design piece, but a plant that gives oxygen even as you sleep.
- Areca Palm: The Tropical Purifier - The Areca Palm brings with it the vibe of tropical holidays and beachside breezes. But beyond its looks, it's one of the best plants that supply oxygen all day long. With its ability to humidify the air and filter out indoor toxins, it's no surprise this plant has found favour in modern homes and workspaces. However, this beauty requires a bit more attention; regular watering, occasional trimming, and indirect light are essential to keep it happy. The payoff? Cleaner air, a calmer mind, and a touch of resort-style luxury right in your living room.
- Tulsi: Sacred and Scientific - Few plants hold as much reverence in Indian households as Tulsi, and with good reason. Not only is it sacred and steeped in tradition, but it also proves itself a strong contender in the list of plants that give oxygen 24 hours. Tulsi emits oxygen for up to 20 hours a day, absorbing harmful pollutants like carbon dioxide, carbon monoxide, and sulphur dioxide. Add to that its healing qualities, relief from colds, headaches, and mild stomach issues, and you have a household hero rooted in both culture and science.
- Orchids: Elegant and Efficient - If you thought Orchids were just delicate showpieces, think again. These flowering wonders are also indoor plants that release oxygen through the night, thanks to a unique CAM (Crassulacean Acid Metabolism) photosynthesis process. Orchids are also known for purifying indoor air by removing xylene, a toxin commonly found in paints and glues. They don't just make your home look beautiful; they help make it breathable. And let's be honest, that pop of colour on a window ledge or side table? Irresistible.
- Christmas Cactus: A Festive Freshener - Often associated with the holiday season, the Christmas Cactus is more than just a seasonal accent. It's one of the rare 24-hour oxygen-releasing plants that can quietly purify your surroundings while gracing your space with trailing green arms and occasional bursts of bloom. Adaptable to low light and forgiving in care, this plant is ideal for indoor settings with limited sunlight. Placed on a hallway shelf or in your bedroom, the Christmas Cactus brings charm while doubling as décor and a natural air purifier.
