Many people turn to cannabis to unwind, ease anxiety, or soothe pain, but not all cannabis products affect the body the same way—especially when it comes to sleep. Cannabis-derived products Cannabidiol (CBD) is often the go-to for those seeking relaxation without the high, while tetrahydrocannabinol (THC) delivers the psychoactive effects. Now, there is an ongoing debate on whether THC is helpful or detrimental to sleep.

How Does It Impact Sleep?

According to experts, while going high on THC may lead you to fall asleep quickly, it can affect different stages of your sleep because it interacts with receptors in your brain. "While THC initially decreases sleep onset time by interacting with cannabinoid receptors and modulating neurotransmitter systems, it significantly alters normal sleep architecture — typically increasing deep sleep while suppressing crucial REM sleep," said Dr Jason Singh, Chief Medical Officer at One Oak Medical Group. He also noted that THC can impact sleep patterns differently in the long term.

Sleep Foundation says 70% of young adults use cannabis recreationally to improve their sleep, and 85% of medical marijuana users claim it helps because it relieves pain. Singh said his patients agree, but there is a catch. He underscored that although all his patients report subjective improvements in sleep quality, objective measurements do reveal more fragmented sleep patterns.

Falling asleep in a high state may increase non-REM sleep, which might make you feel well-rested. However, it also reduces the time spent in REM (rapid eye movement) sleep—the stage associated with dreaming, emotional processing, and memory improvement. According to the Sleep Foundation, adults need about two hours of REM sleep each night.

Singh added, “With regular use, tolerance develops as CB1 receptors downregulate in the brain and this diminishes cannabis's sleep-inducing effects over time. When use stops, withdrawal commonly causes REM rebound and insomnia.”

Long-Term Effects On Brain

Although people with chronic pain may notice better sleep while using cannabis, experts often advise against its use as the sole sleep aid. "I usually tell my patients that while cannabis may temporarily improve sleep initiation, its disruption of normal sleep cycling long-term is not helpful for sleep quality,' Dr Singh said. The Sleep Foundation also recommends that children and adolescents avoid cannabis for sleep due to its effects on brain development.

Over time, long-term cannabis use may alter the structure and function of the brain. A 2018 review in The American Journal of Drug and Alcohol Abuse found that heavy cannabis use can impair thinking and memory for at least a week after use. Brain imaging studies have shown smaller brain regions involved in memory, learning, and emotional regulation in cannabis users.

Regular users who stop may experience withdrawal symptoms such as irritability, low mood, appetite changes, and sleep issues. However, according to a 2017 review in Substance Abuse and Rehabilitation, brain receptors begin recovering within two days and may return to normal in about four weeks.

Sometimes body pain can be quite difficult to figure out. ‘Is it my shoulder muscle, or is it shoulder joint that’s causing me pain?’ We have all had these questions and struggled while answering them at the doctor’s office. This is a common experience that we all go through, and it can make things like finding what medication will help elevate the pain difficult.

So how do doctors figure this out? Explaining this in a video, Dr Pooja Chopra MD, shares a post on Instagram. Posted on 8th September, in the video caption Dr Chopra explained, “As a PM&R and Pain specialist, my first job is to be a detective. Tracing pain back to its precise source is the most critical step, because each source requires a completely different treatment plan.” She further goes on to give a simplified guide to help people understand their pain better. Understanding where the pain comes from can help people feel more at ease as well as figure out how serious the problem could be.

How To Tell Whether Your Muscle Is Causing Pain, Your Joint Or Nerve?

Muscle Pain

Muscle pain, also called myofascial pain, feels like a dull, deep ache. When you press on the sore spot, you'll feel tenderness and might even find what feel like tight knots or bands. This kind of pain gets worse when you use the muscle that's hurt, but it often feels better with simple things like resting, putting a heating pad on it, or doing some gentle stretches. You can usually point with one finger to exactly where it hurts.

Joint Pain

Joint pain, or articular pain, is a deep, internal ache that feels very stiff. It's not on the surface; it feels like it's coming from inside the joint itself. You might feel a sharp pain when you make a specific movement, like reaching high above your head. This type of pain is often at its worst when you first wake up in the morning, but it tends to get better as you start moving around and warm up the joint. Because the pain is deep, it can be hard to say exactly where it is.

Nerve Pain

Nerve pain, also known as neuropathic pain, is the most distinct kind of pain. It feels like sharp, shooting, burning, or "electric" shocks. People often describe it as a tingling sensation, like "pins and needles," or even numbness. A key sign of nerve pain is that it travels along a clear path, for example, from your neck all the way down your arm. This pain can come on unexpectedly, even when you're completely still and not moving the body part.

It's important to remember that these types of pain can be linked. For example, a problem with a joint could make the muscles around it tense up in a protective spasm, which could then pinch a nearby nerve. This is why a proper diagnosis from a specialist is so important. They use advanced tools like diagnostic ultrasound, which lets them see exactly what's happening inside your body, so they can treat the root cause of the pain precisely.

A new study has pointed out that people who have chronic insomnia could be at higher risk of dementia. One of the best things a person can do to recover from a tiring day, whether it is from a stressful day or after a tiring workout. However, it is not easy for everyone, there are many people who suffer with sleep problems like chronic insomnia.

An estimate of 16.2% of people around the globe suffer with insomnia according to 2025 Sleep Medicine Reviews, which is a condition that makes it hard to fall or stay asleep. A big number of these people have what's called chronic insomnia, meaning they've had this problem for at least three months, with poor sleep happening three or more nights a week.

Previous studies have already connected insomnia to serious health problems like heart disease and diabetes. But now, a new study in the medical journal Neurology has found an even more concerning link: people with chronic insomnia might be at a much higher risk for developing dementia and other memory problems. The study suggests that their brains could be aging faster as a result.

How Does Insomnia Cause Dementia?

For this study, researchers followed 2,750 older adults for an average of five and a half years. At the beginning, everyone was mentally healthy. The researchers found that the people who had chronic insomnia had a 40% higher chance of developing dementia or mild cognitive impairment (MCI).

Researchers explain that this is a huge finding because it means chronic insomnia could be a bigger risk factor for memory loss than having both high blood pressure and diabetes. They also discovered that those who slept less had more of the tell-tale signs of Alzheimer's disease in their brains, like amyloid plaques, and other signs of damage to their brain's blood vessels. This shows that poor sleep isn't just about feeling tired—it's linked to real, physical changes in the brain.

Why You Should Prioritize Sleep?

Experts believe that a big part of the problem is that insomnia is often overlooked. Many older adults just assume that bad sleep is a normal part of getting older. However, doctors stress that chronic insomnia is a real medical issue that goes beyond typical age-related changes. They urge doctors to start talking to their patients about their sleep habits during every check-up.

The good news is that chronic insomnia is a treatable condition. The main treatment is a type of talk therapy called Cognitive Behavioral Therapy for Insomnia (CBT-I). The hope is that by recognizing and treating insomnia, doctors can help protect a person's brain health for years to come.

How Does Insomnia Affect Our Memory

Previous studies have shown that our cognitive abilities are affected by how much we sleep. A 2020 study published in the Journal of Neuroinflammation, explained that there is a strong connection between a person's sleep and their risk of developing Alzheimer's. We know that sleep is crucial for learning and creating memories. Studies have found that a lack of sleep and conditions like insomnia are not just a symptom of Alzheimer's—they may also play a role in its development.

This means that sleep disorders can have a significant impact on whether someone gets Alzheimer's and how fast the disease progresses. Because of this, it's important for doctors to pay more attention to sleep issues when diagnosing and treating patients. By properly screening for and managing sleep disorders, we might be able to help prevent or slow down the progression of Alzheimer's disease.

A new study from Stanford University suggests that daylight saving time isn't just an inconvenience; it could actually be bad for our health. The research shows that our twice-a-year routine of changing the clocks disrupts our bodies' natural rhythms, which can lead to serious health issues. This is a big deal because it provides the first real scientific evidence that this time-switching practice has a biological cost.

What is Daylight Saving Time?

According to the Sleep Foundation, daylight saving time (DST) has been an official practice in most of the United States since 1966. Only a few places, like Hawaii and parts of Arizona, don't follow it. The routine is simple: on the second Sunday in March, we set our clocks forward by one hour, losing an hour of sleep. Then, on the first Sunday in November, we set them back, gaining that hour of sleep. This is why many people remember it as "Spring Forward, Fall Back."

How Daylights Saving Time Affects Our Health

According to the study, if the U.S. got rid of daylight saving time and stayed on standard time all year, it could prevent thousands of strokes and significantly reduce obesity. The researchers, using mathematical models and data, estimated that this single change could prevent 300,000 strokes and lead to 2.6 million fewer people with obesity every year. This adds to what we already know about the negative effects of the time change, such as a spike in heart attacks and car crashes in the days after we lose an hour of sleep in the spring.

How Does Daylight Saving Time Affect Sleep?

Our body's internal clock is heavily influenced by light. When the clocks change, the amount of natural light we get in the morning and evening shifts. This can throw off our sleep-wake cycle, making it harder to feel alert in the morning and sleepy at night.

The “spring forward” change is particularly hard on us. One study found that on the Monday after the time change, the average person gets 40 minutes less sleep. This lack of sleep can build up over time, affecting our mood and increasing the risk of accidents.

While the "fall back" change in November can give us an extra hour of sleep, some people still struggle to adjust to the new schedule. For most people, the effects fade after a few days, but some studies suggest that others never fully adjust, leading to ongoing health problems.

Why Time Changes Mess With Our Bodies

The core problem lies in our body's internal clock, or circadian rhythm. Think of it as the conductor of an orchestra, directing all your body's processes. When it's working well, everything is in sync. But when it's thrown off, like by getting light at the wrong time of day, your body's systems can become disorganized.

This can weaken your immune system, mess with your sleep, and increase your risk for diseases like stroke and obesity. The study found that switching between standard and daylight saving time is the worst thing we can do for our body clock, much worse than staying on either time year-round. It's a bit like having the conductor suddenly change the tempo for no reason—the whole orchestra, or in this case, your body, gets thrown off.
