Waking up feeling tired, even after a full night's sleep? A blood oxygen level of 87% while sleeping might be the culprit. Ideally, your oxygen saturation (SpO2) should stay between 95-100%. An SpO2 of 87% indicates hypoxemia, meaning your blood isn't carrying enough oxygen.
So, what could be causing this? Conditions like sleep apnea, COPD, asthma, and even certain medications can lower oxygen levels during sleep. Obesity can also contribute.
What should you do? **Don't ignore this!** Consistent low oxygen levels can strain your heart and brain. Consult with your doctor immediately. They can perform tests, such as a sleep study (polysomnography), to determine the underlying cause. Depending on the diagnosis, treatment options might include lifestyle changes, oxygen therapy, CPAP machines (for sleep apnea), or medications. Early intervention is key to protecting your long-term health and ensuring restful, oxygen-rich sleep.
