<p>Forget about bedtime stories; plants have their own way of whispering in the dark, which involves a unique exchange of gases.</p>
<p>Picture this: While you&#8217;re tucked away in bed, dreaming of adventures (or struggling with nightmares), your leafy friends in the garden are releasing carbon dioxide (CO2) into the night air.</p>

<p>During the day, plants are the heroes of <a target="_blank" rel="nofollow noopener" href="https://www.ucl.ac.uk/culture-online/case-studies/2023/feb/it-true-plants-release-co2-during-night-and-i-should-not-have-one-my-room#:~:text=You%20are%20correct%2C%20plants%20do,release%20CO2%20during%20the%20day.&amp;text=This%20is%20a%20part%20of,undertake%20a%20process%20called%20photosynthesis.">the photosynthesis story</a>. They absorb carbon dioxide and release oxygen, providing us with the fresh air we breathe. But when night falls, the tables turn.</p>
<p>Plants switch to respiration mode after dark.</p>
<p>It&#8217;s their time to breathe out and release a bit of carbon dioxide.</p>
<p>Don&#8217;t worry; your garden is not doing anything out of the ordinary. The amount of CO2 plants release is relatively small, and it&#8217;s a natural part of their metabolic rhythm.</p>

<h2>You might be wondering, does the CO2 plants release cause a lack of oxygen and pose any health risks?</h2>
</div>
<div class="segment-body">
<div class="text">
<div class="">
<p>Well, that&#8217;s because the levels of carbon dioxide released by plants at night are generally not harmful to us. Outdoor air usually contains around 0.04% CO2, which is a relatively low concentration.</p>
<p>It&#8217;s also essential to distinguish between carbon dioxide (CO2) and carbon monoxide (CO), the latter of which is often referred to as the &#8220;silent killer&#8221; gas. Unlike carbon dioxide, carbon monoxide is a colourless, odourless gas produced by incomplete combustion processes.</p>
<p>Coming back to CO2, while humans and animals do exhale a more significant amount of CO2, it&#8217;s well within safe limits.</p>
<p>Indoor spaces with poor ventilation can sometimes accumulate higher levels of CO2, but the overall impact on our health is minimal when proper ventilation is maintained.</p>
