Are Plants in the Bedroom at Night Bad for Your Health?

Updated: May 31

The idea of placing plants in the bedroom has been a topic of debate for many years. While some people believe that having plants in the bedroom is beneficial for health and well-being, others think it might be harmful, especially at night. In this blog, we'll explore the myths and facts surrounding this topic and determine whether plants in the bedroom are good or bad for your health.

The Myth: Plants Compete for Oxygen at Night

One common myth is that plants compete with humans for oxygen at night, potentially leading to oxygen deprivation. This concern stems from the fact that during the night, most plants switch from photosynthesis to respiration. While photosynthesis absorbs carbon dioxide and releases oxygen, respiration does the opposite – plants take in oxygen and release carbon dioxide.

The Fact: Minimal Impact on Oxygen Levels

The truth is, the amount of oxygen that plants consume at night is negligible and does not significantly impact the oxygen levels in your bedroom. The oxygen that plants use during respiration is far less than the oxygen produced during photosynthesis throughout the day. For most homes, ventilation and air exchange with the outside environment ensure that oxygen levels remain stable and healthy.

Benefits of Having Plants in the Bedroom

  1. Improved Air Quality: Many houseplants are known for their air-purifying abilities. Plants like the snake plant, peace lily, and spider plant can remove toxins such as formaldehyde, benzene, and trichloroethylene from the air. Cleaner air can lead to better respiratory health and overall well-being.

  2. Increased Humidity: Plants release water vapor into the air through a process called transpiration. Higher humidity levels can help alleviate respiratory issues, dry skin, and even improve sleep quality, especially in dry climates or during winter months.

  3. Stress Reduction: Numerous studies have shown that being around plants can reduce stress and anxiety. The presence of greenery can create a calming environment, which is conducive to relaxation and better sleep.

  4. Enhanced Sleep Quality: Some plants, like lavender and jasmine, are known for their soothing fragrances. These scents can promote relaxation and improve sleep quality. Additionally, certain plants, such as the snake plant and aloe vera, release oxygen at night, further enhancing the sleep environment.

Considerations for Placing Plants in the Bedroom

  1. Allergies: Some individuals may be allergic to specific plants or their pollen. It's important to choose hypoallergenic plants or those that do not produce significant amounts of pollen.

  2. Maintenance: Ensure that the plants you choose are suitable for indoor environments and do not require excessive care. Overwatering can lead to mold growth, which can negatively affect indoor air quality.

  3. Pest Control: Regularly check plants for pests, such as spider mites or aphids, to prevent infestations that could affect your health and the health of your plants.


The idea that plants in the bedroom are bad for your health is largely a myth. On the contrary, many plants offer numerous benefits, including improved air quality, increased humidity, and enhanced sleep quality. By choosing the right plants and maintaining them properly, you can create a healthy, relaxing environment that promotes better sleep and overall well-being. So go ahead and bring some greenery into your bedroom – your body and mind will thank you for it.
