Does CBD make you tired? How to mitigate side effects
Learn whether CBD can cause tiredness and explore effective strategies to minimize its side effects. Learn the science with this guide.

Cannabidiol (CBD) has emerged as a popular supplement for promoting relaxation, reducing anxiety, and enhancing overall wellness. Unlike its counterpart tetrahydrocannabinol (THC), CBD is non-psychoactive, meaning it doesn't produce the "high" associated with cannabis use.
However, some users report feeling unusually tired or drowsy after taking CBD. This article delves into whether CBD truly causes tiredness, the mechanisms behind this effect, and how to manage it effectively.
What is CBD?
CBD is one of over a hundred cannabinoids found in the cannabis plant, particularly in Cannabis sativa species. It interacts with the body's endocannabinoid system (ECS), which plays a crucial role in regulating various physiological processes, including mood, sleep, appetite, and immune response.
Unlike THC, CBD does not bind strongly to the CB1 receptors in the brain, which are responsible for the psychoactive effects of cannabis. Instead, CBD influences the ECS indirectly, contributing to its therapeutic potential without inducing euphoria.
CBD is available in various forms, including oils, tinctures, capsules, edibles, and topical applications, each offering different methods of consumption and onset times. Its versatility makes it a favored choice for those seeking natural remedies for tension, discomfort, and other wellness-related issues.
The relationship between CBD and tiredness is multifaceted. While CBD is generally regarded as a calming and relaxing agent, some users experience drowsiness or fatigue after consumption. The degree to which CBD induces tiredness can vary based on several factors, including dosage, individual body chemistry, and the specific CBD product used.
Does CBD cause tiredness?
The occurrence of tiredness or drowsiness after taking CBD may be attributed to several underlying mechanisms. These include its interaction with the ECS, its impact on neurotransmitter activity, and factors related to dosage and timing.
Interaction with the endocannabinoid system
CBD interacts with the ECS by influencing the activity of cannabinoid receptors and other signaling pathways. The ECS is integral to maintaining homeostasis in the body, and its modulation by CBD can lead to a state of relaxation, which may naturally result in feelings of tiredness.
Although CBD doesn't bind directly to CB1 receptors like THC does, it can influence their activity indirectly. By modulating these receptors, CBD can affect neurotransmitter release, leading to calming effects that may promote sleepiness.
Located primarily in the immune system, CB2 receptors are also affected by CBD, contributing to its beneficial properties.
Impact on neurotransmitters
CBD influences the levels and activity of various neurotransmitters in the brain, which play a pivotal role in regulating mood, anxiety, and sleep.
CBD has been shown to interact with serotonin receptors, enhancing mood and reducing feelings of overwhelm. Lower tension levels can lead to a more relaxed state, which may contribute to feelings of tiredness.
By potentially supporting the production of gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter, CBD can enhance relaxation and reduce neuronal excitability, leading to a calmer and potentially drowsy state.
Serving size and timing
The amount of CBD consumed and the time of day it is taken significantly influence whether it causes tiredness. Larger amounts of CBD are more likely to induce drowsiness as they exert a stronger calming effect on the ECS and neurotransmitter activity.
Taking CBD in the evening or before bedtime can naturally align with its sedative effects, promoting better sleep quality. Conversely, taking CBD earlier in the day may minimize feelings of tiredness and support daytime relaxation without inducing drowsiness.
How to mitigate CBD-induced tiredness
For those who experience unwanted tiredness from CBD, there are several strategies to mitigate this side effect. Adjusting dosage, choosing the right product, timing intake appropriately, and combining CBD with other wellness practices can help balance the desired effects with minimal sleepiness.
Adjust your serving size
One of the most effective ways to manage CBD-induced tiredness is to adjust the dosage. Starting with a lower dose and gradually increasing it allows you to find the optimal amount that provides therapeutic benefits without causing excessive drowsiness.
- Start Low: Begin with a small amount, such as 5-10 mg of CBD, and monitor your body's response.
- Incremental Increases: If necessary, slowly increase the dosage by 5 mg increments until you achieve the desired effects without feeling overly tired.
- Personalization: Everyone's body chemistry is different, so personalizing your dosage is key to minimizing side effects while maximizing benefits.
Choose the right CBD product
The type of CBD product you use can significantly impact whether it makes you tired. Different formulations offer varying effects based on their cannabinoid and terpene profiles.
- Full Spectrum CBD: Like what is found in Sunmed’s Full Spectrum Anytime CBD Gummies contains a range of cannabinoids and terpenes that work synergistically, potentially enhancing the overall effects. However, some terpenes may promote relaxation and drowsiness.
- Broad Spectrum CBD: Like Sunmed’s Organic Broad Spectrum CBD Tincture it is similar to full spectrum but without detectable levels of THC, offering a balanced effect without psychoactive properties.
- CBD Isolate: Pure CBD with no other cannabinoids or terpenes, which may reduce the likelihood of drowsiness but might also limit the entourage effect benefits.
- Terpene-Rich Formulations: Products infused with energizing terpenes like limonene or pinene can counteract drowsiness and promote alertness. Our Beyond Sativa CBD Gummies are a great example of this feel-good boost.
Selecting a product tailored to your desired effects can help mitigate unwanted tiredness.
Timing your CBD intake
When you take CBD plays a crucial role in how it affects your energy levels.
- Morning Consumption: Taking CBD in the morning can provide a calm and focused start to your day without inducing drowsiness.
- Evening Consumption: If you prefer taking CBD in the evening, do so a few hours before bedtime to allow its calming effects to facilitate a restful night's sleep.
- Consistent Schedule: Maintaining a consistent intake schedule helps your body adapt to CBD's effects, allowing for better management of side effects like tiredness.
Combine CBD with other practices
Integrating CBD use with other wellness practices can enhance its benefits and reduce the likelihood of side effects.
- Hydration: Staying well-hydrated can help minimize dry mouth, a common side effect of CBD, and support overall bodily functions.
- Balanced Diet: Consuming a nutritious diet ensures that your body has the necessary nutrients to process CBD effectively, potentially reducing feelings of fatigue.
- Physical Activity: Engaging in regular physical activity can boost energy levels and counteract any drowsiness caused by CBD.
- Mindfulness Practices: Incorporating meditation or deep-breathing exercises can enhance the calming effects of CBD without leading to excessive tiredness.
What are some best practices for CBD use?
Adopting best practices for CBD consumption ensures that you experience its benefits while minimizing potential side effects like tiredness.
