Introduction
You may have started taking CBD oil to help you stay calm during a busy afternoon or to help you maintain focus during a long shift. However, instead of feeling refreshed and alert, you find yourself feeling slightly heavy-eyed or ready for a nap. If you are asking "why does CBD oil make me tired," you are certainly not alone. While many people use hemp-derived products to support their daily energy levels, others find that it has a more relaxing effect than they expected.
At Swiss Peak Health, we believe that understanding how your body interacts with wellness supplements is the first step toward achieving your peak. In this guide, we will explore the biological reasons why CBD can sometimes lead to tiredness, how dosage plays a role, and what you can do to adjust your routine so you feel exactly how you want to.
Whether you are a seasoned user or just starting your journey with our CBD products, knowing the "why" behind your body's response helps you use these tools more effectively. Results vary for everyone, but with a little bit of knowledge, you can find the perfect balance for your lifestyle.
Quick Answer: CBD oil can make you feel tired primarily due to the "biphasic effect," where higher doses tend to be more relaxing while lower doses are often more energising. It may also be due to individual body chemistry, the presence of specific terpenes like myrcene, or a high-strength formula that your body isn't yet used to.
How CBD Interacts With Your Body
To understand why you might feel sleepy, it helps to understand the endocannabinoid system (ECS). The ECS is a complex cell-signalling network that exists throughout your body, regardless of whether you use hemp products or not. It plays a vital role in maintaining "homeostasis," which is just a fancy way of saying internal balance.
The ECS manages things like your sleep-wake cycle, mood, and how you respond to physical discomfort. It works using three main components: endocannabinoids (molecules made by your body), receptors (which these molecules bind to), and enzymes (which break them down).
CBD, or cannabidiol, is a phytocannabinoid—a cannabinoid that comes from a plant. Unlike THC, which binds directly to receptors in the brain to create a "high," CBD works more like a manager. It encourages your body to use its own endocannabinoids more effectively and prevents enzymes from breaking them down too quickly.
By supporting this system, CBD may help the body find its natural rhythm. For some, that rhythm involves feeling more alert. For others, particularly those who have been living under significant pressure or have been lacking rest, the "balance" the ECS provides might manifest as a sudden, deep need for sleep.
The Biphasic Effect: Why Dosage Matters
One of the most important concepts in the world of CBD is the "biphasic effect." This means that the same substance can have different effects on the body depending on the amount you take.
Think of it like caffeine. A small cup of tea might make you feel gently alert, but a massive overdose of caffeine can actually leave some people feeling jittery and then strangely exhausted. CBD works in a similar, albeit opposite, way.
- Low to Moderate Doses: For many people, a smaller amount of CBD (like a few drops of a 500mg or 1000mg oil) may support alertness and focus. It helps quiet the "background noise" of the day, allowing you to concentrate on tasks.
- High Doses: When you move into higher strengths—such as our 6000mg CBD Oil | 30ml High Strength or 12000mg CBD Oil | 100ml High Strength—the effect often shifts. In these quantities, CBD is much more likely to promote a sense of deep relaxation and contentment. If you take a large dose in the morning, you might find yourself feeling more drowsy than you intended.
Bottom line: If your CBD is making you tired during the day, the first thing to look at is your dose. You may simply be taking more than your body needs for daytime use.
The Role of GABA and Adenosine
Beyond the ECS, CBD interacts with other systems in the brain that govern how tired or awake we feel. Two key players here are GABA and adenosine.
GABA (Gamma-Aminobutyric Acid) is often called the brain's "brake pedal." It is a neurotransmitter that helps slow down the central nervous system when it gets too excited. When GABA activity increases, you feel calmer and more relaxed. Some studies suggest that CBD may help support GABA activity. If your "brake pedal" is pressed a little too hard during the day, you will naturally start to feel tired.
Adenosine is a chemical that builds up in your brain throughout the day. The more adenosine you have, the sleepier you feel. When you sleep, your body clears this chemical out so you can wake up refreshed. Caffeine works by blocking adenosine receptors, which is why it keeps you awake. Some researchers believe CBD might influence how the body interacts with adenosine, potentially helping you feel more ready for rest when the day is done.
Key Takeaway: CBD does not act as a traditional sedative. Instead, it interacts with your body's natural "calming" chemicals to help you reach a state where sleep is possible. If you are already lacking rest, these signals may feel stronger.
Full-Spectrum vs. Isolate: The Role of Terpenes
Not all CBD oil is created equal. The type of extract you choose can have a significant impact on whether you feel "sleepy" or "steady."
Full-Spectrum CBD
This extract contains all the compounds found in the hemp plant, including other minor cannabinoids and terpenes. Terpenes are the aromatic oils that give plants their smell. Some terpenes, such as myrcene and linalool (also found in lavender), are well-known for their relaxing properties. If your oil is rich in these specific terpenes, it is far more likely to make you feel tired.
Broad-Spectrum CBD
Similar to full-spectrum, this contains a variety of plant compounds but has the THC filtered out to non-detectable levels (0.0%). It still offers the benefits of terpenes, so the "tiredness" factor can still apply if the terpene profile is leaning toward relaxation.
CBD Isolate
This is pure CBD with nothing else. Because it lacks the terpenes and other cannabinoids, some people find it "cleaner" for daytime use, though they may miss out on the "entourage effect"—the idea that plant compounds work better when they stay together.
At Swiss Peak Health, we ensure our products are clearly labelled so you know exactly what you are getting. If you are finding a full-spectrum oil too heavy for your morning routine, you might consider a different strength or format.
CBD vs. THC: Clearing Up the Confusion
A common misconception is that CBD makes you tired for the same reason that marijuana does. This is incorrect. The "heavy," sedated feeling often associated with cannabis is primarily caused by THC (tetrahydrocannabinol).
THC is intoxicating and has a direct sedative effect. In the UK, legal CBD products must contain virtually no THC (less than 0.2% or 0.0% depending on the specific standard). Our products are 0.0% THC, meaning you aren't feeling "high" or experiencing the lethargy that comes with THC.
If you are feeling tired after taking a high-quality, THC-free product, it is your body's own response to the CBD and the terpenes, not a psychoactive "stoned" effect.
Factors That Influence Your Individual Response
Everyone’s body chemistry is unique. This is why one person can drink three espressos and go to sleep, while another is awake all night after one cup. Several factors influence how CBD oil makes you feel:
- Metabolism: How quickly your body processes the oil affects how long it stays in your system and how intensely you feel it.
- Body Weight and Composition: Generally, your mass can dictate how much CBD is needed to produce a specific effect.
- Current Stress Levels: If you have been "running on fumes" for weeks, CBD may help lower your stress response. When that high-alert state drops, you might suddenly realise just how exhausted you actually are.
- Consistency: When you first start taking CBD, your body has to get used to it. Initial tiredness often fades after a week or two of consistent use as your ECS finds a new baseline.
How to Adjust Your Routine to Avoid Daytime Tiredness
If you love the benefits of CBD—like feeling more grounded and balanced—but hate the afternoon slump, you don't have to stop using it. You just need to optimise your routine.
Start Low and Go Slow
If you are currently using a high-strength oil and feeling sluggish, try dropping your dose by half. You can always add more later. Our lower-concentration oils are excellent starting points for those who want to stay active and alert.
Change Your Timing
If CBD makes you tired, use it to your advantage. Shift your main dose to about an hour before you want to go to bed. This allows the relaxing effects to peak just as you are winding down. For daytime support, try taking a much smaller "micro-dose" in the morning.
Try Different Formats
The way you take CBD affects how fast it works and how long it lasts.
- CBD Oils: Taken under the tongue, these enter the bloodstream quickly. The effects might be more intense but wear off sooner—see our 3000mg CBD Oil | 30ml Mid-Strength for a mid-strength oil option.
- CBD Gummies: These have to pass through the digestive system. This leads to a slower, more sustained release of CBD. Many people find our CBD Gummy Bears 1200mg provide a more "level" experience during the day without the sudden peaks that can cause drowsiness.
- Topicals: If you are using CBD for physical comfort in a specific area, our Swiss Peak 1000mg CBD Muscle & Joint Balm allows you to target that spot without the CBD entering your bloodstream in large amounts, which usually avoids any systemic tiredness.
Hydrate and Eat
Taking CBD on an empty stomach can sometimes lead to a more intense "hit." Try taking your oil or gummies after a light meal. Also, ensure you are drinking plenty of water, as dehydration can often mimic the feeling of CBD-induced fatigue.
Note: If you are taking any prescription medication, it is important to consult a healthcare professional. CBD can interact with certain medications in a way that changes how they are metabolised, which could lead to increased side effects like tiredness.
Building a Wellness Routine That Works
CBD is rarely a "one-hit-wonder" solution. It works best when integrated into a healthy lifestyle. If you are feeling tired, look at the bigger picture of your wellness routine.
- Pair with Matcha: If you need to stay sharp, consider our Matcha Gummies. Matcha contains a unique combination of caffeine and L-theanine, which provides a calm, focused energy without the jitters. Combining this with a low dose of CBD can create a very balanced daytime state.
- Prioritise Sleep Hygiene: If you are using CBD to help with restless nights, make sure you are also following good sleep practices. Dim the lights, put away screens an hour before bed, and keep your room cool. Our Sleep Mushroom Cacao Blend is another great way to support this evening transition.
- Monitor Your Energy: Keep a simple journal for a week. Note when you take your CBD, the dose, and how you feel two hours later. You will quickly see patterns that help you "dial in" your perfect dose.
Choosing the Right CBD Product for Your Goals
At Swiss Peak Health, we offer a wide range of strengths because we know that everyone's "peak" is different.
For Daytime Focus:
We recommend starting with our lower-concentration oils (500mg or 1000mg) or our gummies. If you prefer a gummy format, try our CBD Gummy Peach Rings 3200mg for a measured, convenient option.
For Evening Relaxation:
This is where our higher-strength oils shine. If you want to support a deep sense of rest, our 6000mg CBD Oil | 30ml High Strength, 12000mg CBD Oil | 100ml High Strength, or even our ultra-high strength 25000mg CBD Oil | 100ml High Strength options are designed for those who need a more significant impact.
Bottom line: Tiredness is a sign that your dose, timing, or product type isn't quite aligned with your current goals. By making small adjustments, you can enjoy the benefits of CBD while staying as energised as you need to be.

FAQ
Does CBD oil always make you tired?
No, CBD does not always make people tired; its effects are often "biphasic," meaning small doses may feel energising while larger doses tend to be more relaxing. Many people use low-strength CBD during the day to support focus and a calm mood without feeling any drowsiness at all.
How long does the tiredness from CBD last?
If you feel drowsy after taking CBD, the effect typically lasts as long as the compound is active in your system, which is usually between 2 and 6 hours depending on your metabolism and whether you took it as an oil or a gummy. Drinking water and moving around can often help you feel more alert more quickly.
Can I take CBD oil in the morning and still be productive?
Yes, you can absolutely take CBD in the morning and stay productive, provided you find the right dose for your body. Many users find that a small morning dose helps them stay calm and focused under pressure; the key is to start with a very low dose and monitor how you feel before increasing it. If you prefer a milder approach, consider a mid-strength option like the 3000mg CBD Oil | 30ml Mid-Strength or try a gummy format such as the CBD Gummy Bears 1200mg.
Why does CBD make me tired the next day?
Feeling tired the next day is rare with CBD, as it is usually processed by the body within a few hours, but it can happen if you take a very high dose late at night. Often, "next-day tiredness" is actually your body catching up on a "sleep debt" after finally being able to relax and rest deeply.
