Does CBD Make You Tired the Next Day? Here's What to Know

If you're new to CBD use or exploring it as a natural sleep aid, you may wonder: Will CBD make me tired the next day? This is a common question, especially for people using CBD for chronic pain, stress response, or sleep disorders.

The short answer? For most people, CBD does not cause next-day fatigue. But as with any chemical compound that interacts with the central nervous system, your experience can depend on a few key factors.

What Does CBD Do in the Body?

CBD, short for cannabidiol, is a natural compound derived from the hemp plant, a variety of the cannabis sativa species. It interacts with the body's endocannabinoid system, which helps regulate sleep-wake cycles, mood, pain, inflammation, and other various functions of the human body.

CBD interacts with cannabinoid receptors, and may also influence serotonin receptors linked to mood and sleep. While it doesn’t produce the high associated with THC, many users report a calming effect, especially in the evening.

Can CBD Make You Tired the Next Day?

Some people worry that taking CBD for sleep might lead to daytime sleepiness, drowsiness, or a "hangover" the next morning. Here's what the evidence and anecdotal evidence suggest:

• Low doses of CBD may actually promote wakefulness and alertness.

• Higher doses — particularly when used for sleep — may have sedative effects, especially in full-spectrum CBD products.

• Some users report feeling more rested, while others notice different effects depending on their individual body chemistry or daily routine.

That said, next-day fatigue is not a typical side effect and often relates to other factors, like:

• Taking too much CBD

• Poor sleep patterns or REM sleep disruption

• Mixing CBD with prescription medications or sleep aids

• Using low-quality products that may contain heavy metals or unlisted ingredients

What Impacts Your CBD Experience?

How you feel after using CBD depends on:

• Amount of CBD (mg of CBD) consumed

• Type of product: tincture, capsule, CBD gummies, CBD oil, or CBD topicals

• Whether it’s full-spectrum CBD (contains trace THC), broad-spectrum, or isolate

• The stage of sleep you’re in when CBD kicks in

• Your cortisol levels and how your body handles stress response

• Time of day taken (e.g. night vs morning)

• Any existing health conditions or use of blood thinners

How to Avoid Feeling Tired the Next Day

To ensure your CBD supports better sleep without dragging down your next day, consider the following:

• Start with lower doses and work your way up

• Choose high-quality CBD products with natural ingredients

• Always look for a certificate of analysis or third-party lab test

• Avoid mixing with alcohol or strong sleep aids

• Track your sleep, mood, and cognitive function during your CBD journey

Pro tip: Take your CBD about 30–60 minutes before bed for a good night’s sleep that doesn’t affect your daily activities the next morning.

Potential Benefits Without Grogginess

In fact, many users report waking up with better sleep quality, improved energy levels, and less pain or anxiety. Some human studies suggest CBD may help improve sleep duration, regulate the sleep-wake cycle, and support memory consolidation and immune system function during deep sleep.

Unlike some prescription medications, CBD is less likely to disrupt REM sleep or cause rebound insomnia when discontinued.

Bottom Line: Does CBD Make You Tired the Next Day?

Not usually. CBD generally supports restful sleep without grogginess — especially when taken in the right amount and form for your needs.

If you're worried about unwanted side effects, stick to hemp-derived CBD products from trusted brands that publish third-party lab results and use clean, active ingredients.

CBD can be a helpful tool in your daily routine to support sleep benefits, reduce stress, and promote wellness — without derailing your productivity the next day.
