Sleeping pills are a common solution for people who struggle with insomnia or sleep deprivation. However, they can also be dangerous. The most widely prescribed sleeping pills, benzodiazepines, suppress the brain's ability to wake up in response to threats. This has led to people on sleep medication eating, making phone calls, having sex, and even driving while not fully awake. A new class of hypnotic drugs called dual orexin receptor antagonists (DORAs) is being developed to address this issue. DORAs selectively target the brain's sleep/wake pathways, allowing users to wake up in response to danger signals.

Most people on sleeping pills won't wake up to a fire alarm
Sleeping pills are commonly used to combat insomnia and sleep deprivation, which can significantly impact daily life. However, it is important to note that most sleeping pills are so strong that they can prevent users from waking up to a fire alarm.
Benzodiazepines, the most widely used type of sleeping pill, work by stimulating the brain receptor GABA-A, which induces sleep but also suppresses the brain's ability to process sensory information. This suppression of the brain's 'gatekeeper' function means that even a loud fire alarm may not be enough to wake someone who has taken these sleeping pills. In a trial, half of the participants who took benzodiazepines did not wake up at the sound of a fire alarm as loud as someone vacuuming next to their bed.
The risks associated with the use of benzodiazepines have prompted researchers to develop a new class of hypnotic drugs called dual orexin receptor antagonists (DORAs). DORAs target the brain's sleep/wake pathways more selectively, preserving the brain's ability to respond to danger signals while still promoting sleep. In a trial, mice given the experimental hypnotic drug DORA-22 woke up as quickly as drug-free sleepers when confronted with a threat and were able to fall back asleep just as quickly once the threat had passed.
While DORAs show promising results in mice trials, human clinical trials are needed to further test their benefits and safety. It is important to note that sleeping pills can have side effects and should not be used long-term without consulting a healthcare provider. Mixing sleeping pills with other sedatives or alcohol can also be dangerous and may lead to an overdose.

Benzodiazepines suppress the brain's ability to wake up to threats
Sleeping pills are a common solution for those who struggle with sleep. In the United States, around 50 to 70 million individuals have sleep disorders or live with sleep deprivation. However, most sleeping pills are so strong that many people would not be able to wake up to the sound of a fire alarm. In a trial, half of the participants who took widely-used hypnotics did not wake up to the sound of a fire alarm.
Benzodiazepines are the most widely used type of sleeping aid and are among the most commonly prescribed medications. They are often prescribed for anxiety, insomnia, and other purposes. Benzodiazepines work by stimulating the widespread brain receptor GABA-A, which induces sleepiness but also suppresses off-target brain areas, including the 'gatekeeper' that decides which sensory inputs to process. This suppression of the brain's gatekeeper function means that those taking benzodiazepines are less likely to wake up in response to sensory input, such as a fire alarm or intruder.
Due to the risks associated with the use of benzodiazepines, researchers have been developing a new class of hypnotic drugs called dual orexin receptor antagonists (DORAs). DORAs more selectively target the brain's sleep/wake pathways, allowing the brain's sensory gatekeeper to stay vigilant to threats. In a trial, mice that were administered DORA-22 woke up as quickly as drug-free mice when confronted with a danger signal, such as the smell of a fox or an earthquake. After the threat had passed, the mice fell back asleep just as quickly as those given standard sleeping pills.
While DORAs show promise as a safer alternative to benzodiazepines, human clinical trials are needed to further test their benefits and safety.

Dual orexin receptor antagonists (DORAs) are a safer alternative
Sleeping pills are a common solution for those who have difficulty falling or staying asleep. However, they can have side effects and are not recommended for long-term use. Benzodiazepines, the most widely used type of sleeping pill, suppress the brain's ability to respond to sensory information during sleep, making it difficult to wake up to danger signals. This has raised concerns about the safety of these drugs.
Dual orexin receptor antagonists (DORAs) are a newer class of insomnia medications that work differently from traditional sleeping pills. DORAs block signals in the brain that stimulate wakefulness, specifically targeting the brain's sleep/wake pathways. This makes them a safer alternative to benzodiazepines as they allow the brain to stay vigilant to threats while still promoting sleep.
In a trial, mice given the experimental hypnotic drug DORA-22 woke up as quickly as drug-free mice when presented with danger signals such as an alarming sound or the smell of a fox. Importantly, the sleep-inducing effects of DORA-22 continued after the threat had passed, allowing the mice to fall back asleep quickly. DORAs are also less likely to induce drowsiness the next day, reducing the risk of impaired driving ability.
While DORAs appear to be a promising alternative to traditional sleeping pills, more research is needed to fully understand their benefits and safety profile. Human clinical trials are required to confirm the effects observed in mouse studies. Additionally, DORAs may not be suitable for everyone, and they can cause side effects such as daytime drowsiness, headache, and dizziness.
Overall, dual orexin receptor antagonists (DORAs) offer a potential solution for those seeking a safer alternative to traditional sleeping pills. By targeting the brain's sleep/wake pathways and preserving the ability to respond to danger signals, DORAs may provide effective sleep induction without compromising an individual's ability to wake up to potential threats.

Sleeping pills can cause side effects like dizziness and drowsiness
Sleeping pills are designed to help people with sleep disorders like insomnia fall and stay asleep. However, they can also cause side effects, and it is recommended that they are not used long-term. One of the most common side effects is drowsiness, which can last into the day after taking the pills. This can negatively impact an individual's ability to drive, work, or complete daily tasks. In older adults, daytime drowsiness has been linked to falls, broken hips, and car accidents.
Another common side effect of sleeping pills is dizziness. This can be dangerous when combined with the drowsiness caused by the pills, as it can slow reaction times. This is especially problematic for those who need to drive or operate machinery.
Sleeping pills can also cause confusion and memory problems. This is particularly common in older adults, who are more likely to experience health problems from taking sleep medication. In addition, some people experience digestive issues such as constipation, diarrhea, and nausea when taking sleeping pills.
Sleeping pills can also cause a "hangover effect," with approximately 8 out of 10 people experiencing drowsiness and impaired thinking the day after taking sleep medication. This can affect an individual's ability to drive and complete daily tasks.

They can also lead to parasomnia and complex sleep-related behaviours
Sleeping pills can cause parasomnia and complex sleep-related behaviours. Parasomnias are abnormal and undesirable behaviours during sleep and are thought to be due to sleep state instability. They encompass a broad spectrum of events, including abnormal motor, behavioural, and sensory experiences. Parasomnias with sleeping pills may include sleep eating, making phone calls, or having sex while in a sleep state. Sleepwalking (somnambulism) is also a form of parasomnia.
Certain drugs are associated with parasomnias, and the risk is higher for individuals with epilepsy or a history of sleepwalking. Benzodiazepine receptor agonists, antidepressants, antipsychotics, and beta-blockers are possible triggers for sleepwalking. Additionally, the use of hypnotics for insomnia has been linked to sleepwalking.
Complex sleep behaviours can also occur due to sleeping pills, and these rare but dangerous side effects have led to serious injuries and even death. Eszopiclone, zaleplon, and zolpidem are medicines used to treat insomnia that have been associated with complex sleep behaviours, including sleepwalking and sleep driving. These behaviours can occur even after a single dose and may happen with or without the concurrent use of alcohol or other central nervous system depressants.
It is important to note that parasomnias and complex sleep behaviours are challenging to detect once the medication takes effect. Patients may not remember these events, and the underlying mechanisms causing these behaviours are not yet fully understood. Healthcare professionals should advise patients to discontinue the medication if they experience complex sleep behaviours and seek medical advice.

Frequently asked questions
It depends on the type of sleeping pill. Most prescription sleeping pills, known as benzodiazepines, suppress the sleeping brain's ability to wake in response to a threat. In a trial, half of the participants who took these drugs did not wake up at the sound of a fire alarm. However, a newer alternative called DORA-22 has been found to preserve the ability to wake in response to danger signals.
Sleeping pills can cause a range of side effects, including dizziness, prolonged drowsiness, headache, bloating, nausea, abdominal pain, constipation, and rarely, severe allergic reactions or facial swelling. They can also cause a "'hangover effect", with some people experiencing drowsiness the next day.
Benzodiazepines can be addictive and lead to substance use disorder. To lower this risk, healthcare providers only prescribe these sleeping pills for short-term use.
