Getting enough sleep is vital for staying healthy. Sleep helps the body recover, keeps the mind sharp, and plays a key role in mental and physical health. Yet many people struggle to sleep well. In the United States alone, around one in three adults don’t get enough rest. With sleep being so important, it’s useful to understand how the medications we take might affect our ability to sleep.
One group of medications that are very commonly used are called beta-blockers. Doctors often prescribe beta-blockers to people with heart problems or high blood pressure. These drugs work by slowing down the heartbeat.
This helps the heart do its job with less effort and lowers the pressure in the blood vessels. Beta-blockers are also used to treat conditions like chest pain, irregular heartbeats, and heart failure.
Even though beta-blockers help many people manage serious health conditions, they have long been suspected of causing certain side effects, especially related to mental health and sleep.
Some people have worried that these medications might lead to depression, anxiety, sleep problems, or even strange dreams and hallucinations. However, these concerns haven’t always been based on clear evidence.
To learn more, a group of researchers at the Berlin Institute of Health looked closely at these possible side effects. They gathered data from 258 studies, including over 50,000 people who had taken beta-blockers, mostly for high blood pressure. Their goal was to find out if these medicines really do cause mental health problems or sleep difficulties.
The results were surprising. The researchers found that beta-blockers did not increase the risk of depression. People taking beta-blockers were no more likely to feel depressed than those taking other medications or even those taking a fake treatment (called a placebo).
Also, the number of people who stopped taking beta-blockers because they felt depressed was about the same as in the other groups. This is an important finding because it challenges the common belief that beta-blockers often cause depression.
However, when it comes to sleep, the story is a bit different. The study found that people taking beta-blockers were more likely to report sleep issues. Some had trouble falling asleep or staying asleep.
Others experienced unusual or vivid dreams. While these sleep problems were not severe for most people, they happened more often in the group taking beta-blockers than in those taking other medicines.
Interestingly, the most common reason people stopped using beta-blockers was not depression or strange dreams, but feeling tired or fatigued. This feeling of low energy might also be linked to how the medication slows down the heart and reduces the body’s overall activity level.
These findings are useful for both doctors and patients. The study shows that beta-blockers are generally safe when it comes to mental health, and fears about them causing depression may be overblown. But it also highlights the need to pay attention to sleep-related side effects.
If someone already struggles with sleeping well, it may be worth discussing this with their doctor before starting a beta-blocker. And if sleep problems begin after starting the medicine, it’s important to let the doctor know. There may be ways to adjust the dose or try a different treatment if needed.
This study was led by Dr. Reinhold Kreutz and his team and published in the medical journal Hypertension. It adds to our understanding of how medicines affect not just our bodies but also how we sleep and feel emotionally.
As science learns more about these effects, patients and healthcare providers can make better choices together. In the end, managing heart disease while protecting sleep and mental health is possible—and studies like this help show the way.
If you care about high blood pressure, please read studies that early time-restricted eating could help improve blood pressure, and natural coconut sugar could help reduce blood pressure and artery stiffness.
For more health information, please see recent studies about added sugar in your diet linked to higher blood pressure, and results showing vitamin D could improve blood pressure in people with diabetes.
