Getting enough sleep is essential for good health. It helps the brain and body recover, supports memory, strengthens the immune system, and lowers the risk of many long-term health problems.
Even so, about one in three adults do not get enough sleep, making it important to understand how medicines may affect sleep quality.
Beta-blockers are a group of medicines commonly used to treat high blood pressure and other heart conditions.
They work by slowing the heart rate and reducing how hard the heart has to pump. Doctors often prescribe them for heart failure, irregular heartbeats, chest pain, and high blood pressure because they help protect the heart and lower the risk of serious complications.
For many years, some people believed that beta-blockers could cause depression and other mental health problems. Reports of anxiety, hallucinations, nightmares, and poor sleep led to concerns that these medicines might affect the brain as well as the heart.
A new study from the Berlin Institute of Health has taken a closer look at these concerns. The research, published in the journal Hypertension, analyzed data from more than 50,000 people who took part in 258 clinical studies. Most of the studies involved people being treated for high blood pressure.
The results brought reassuring news. The researchers found no evidence that beta-blockers increased the risk of depression. People taking these medicines were no more likely to stop treatment because of depression than people receiving other types of treatment.
However, the study did find that beta-blockers may affect sleep. People taking the medicines reported insomnia, unusual dreams, and other sleep-related problems more often than those using other treatments. Feeling tired or having low energy was also a common reason for stopping the medication.
These findings suggest that beta-blockers are generally safe from a mental health perspective, but they may not be the best choice for everyone who already struggles with sleep. Doctors should consider a patient’s sleep history when deciding which medicine is most suitable.
If you are taking a beta-blocker and notice changes in your sleep, it is important to discuss them with your doctor rather than stopping the medicine on your own. In many cases, your doctor may recommend simple ways to improve sleep or consider changing to another treatment if needed.
The study was led by Reinhold Kreutz and provides strong evidence from a large number of clinical trials. It offers reassurance that beta-blockers are unlikely to cause depression while reminding patients and healthcare providers to pay attention to possible sleep-related side effects.
