Can lack of sleep cause tongue to swell?

Yes, lack of sleep can contribute to tongue swelling, primarily due to increased stress and inflammation in the body. Sleep deprivation can lead to conditions such as sleep apnea, which may cause the tongue to swell due to reduced oxygen levels. Additionally, fatigue can exacerbate existing health issues that may lead to swelling. However, if tongue swelling occurs, it’s essential to consult a healthcare professional for a proper diagnosis.
