If your sleep habits suddenly change during this period, often experiencing difficulty falling asleep or oversleeping, you need to check the medication you are taking. Today, let's take a look at nine types of drugs that can interfere with normal sleep patterns or ability to fall asleep after taking them. β Receptor blocker β The principle of action of receptor blockers is to lower heart rate and reduce the force of blood circulation in the body. They are usually used to treat cardiovascular diseases, including heart failure, arrhythmia, and hypertension. The reasons why these drugs interfere with sleep and specific β The effect of receptor blockers crossing the blood-brain barrier is related. A clinical pharmacologist from Charlotte Medical University in Berlin, Germany, found in a review published in the Journal of Hypertension that, β Receptor blockers increase the risk of abnormal dreams, insomnia, and sleep disorders in people. β Receptor blockers also reduce the production of melatonin, which plays an important role in the sleep wake cycle. Sleep is regulated by two basic mechanisms. The first type is the biological clock, and the second type is sleep homeostasis. β Receptor blockers not only affect sleep homeostasis, but also affect the biological clock. Selective serotonin reuptake inhibitors (SSRIs) of antidepressants, such as prozac, citalopram, and sertraline, treat depression by increasing serotonin levels in the brain. Serotonin is a neurotransmitter that plays an important role in regulating emotions, memory, appetite, sleep, and other functions. When it comes to these types of drugs, their impact on sleep varies from person to person, and the impact of each drug on the same person also varies. However, research has shown that some antidepressants can disrupt sleep, while others have sedative effects. Although the latter can improve sleep quality in the short term, it can lead to problems such as excessive sedation. SSRIs may also cause or exacerbate sleep disorders, such as restless leg syndrome, insomnia, nightmares, rapid eye movement sleep behavioral disorders, and sleep apnea. These types of drugs can cause both drowsiness and insomnia, and their manifestations vary from person to person. Therefore, the effectiveness of each individual and each medication is uncertain. Some people experience sleep interruptions after taking medication, while others sleep well because the medication treats their anxiety and depression. Corticosteroid drugs work by reducing inflammation and reducing immune system activity, and are typically used to treat diseases such as rheumatoid arthritis, inflammatory bowel disease (IBD), asthma, and allergies. Some common corticosteroid drugs, such as cortisone, prednisone, methylprednisolone, and dexamethasone, can keep people awake at night and disrupt the natural sleep wake cycle, especially if these drugs are taken later in the day. Although doctors are not sure about the connection between the two, there is evidence that steroids can affect melatonin levels. Another possible explanation is that corticosteroids are an artificial product of the stress hormone cortisol, which helps regulate the sleep awakening cycle in the human body. People usually have lower levels of cortisol when preparing to sleep at night, and higher levels when waking up in the morning. Taking steroids at night can disrupt this conventional pattern. These types of drugs will definitely cause losses
