Sugar High, Sugar Nap: Why Do I Get Sleepy After Eating Sugar?

In this blog, we discuss why you feel tired and ready for a nap after eating sugar. We also share tips on other healthy alternatives to consider to avoid a sugar crash after eating.

Sugar High, Sugar Nap: Why Do I Get Sleepy After Eating Sugar?

Bearassentials:

  • You get a sugar crash because of your body’s hormonal response after eating carbs.
  • Eat berries, nuts, plain yogurt, oatmeal, and avocados to avoid a sugar crash.
  • Speak to a doctor if you experience increased thirst and frequent urination as well.

Did you know?
Some researchers believe that the desire to rest after consuming sugar may have evolutionary roots. In the wild, finding a source of sugar-rich food would have been rare and valuable, so conserving energy afterward may have been advantageous for survival!

Are you familiar with the post-sugar slump? You know… that irresistible urge to nap after indulging in your favorite sweet treat? This is a phenomenon many of us have experienced, leaving us wondering: “Why do I get sleepy after eating sugar?”

In this blog, we answer this curious query and offer tips on how to stay awake and energized after satisfying your sweet tooth. Let’s dive in!

Why Do I Get Sleepy After Eating Sugar?

Ever wondered, “Why do I get tired after I eat?” Well, several factors contribute to feeling sleepy after consuming sugar, and they involve intricate interactions within your body. Here’s a detailed breakdown:

Insulin Response:

When you eat sugar, especially in refined forms like candy or soda, your blood sugar levels spike quickly. In response, your pancreas releases insulin to help your cells absorb glucose for energy. This sudden increase in insulin can lead to a subsequent drop in blood sugar levels, known as a “sugar crash.” This crash can cause fatigue and drowsiness.

Serotonin and Tryptophan:

Sugar consumption triggers the release of serotonin, a neurotransmitter associated with mood regulation and relaxation. Additionally, tryptophan, an amino acid found in some foods, can increase serotonin levels in the brain. High levels of serotonin can induce feelings of calmness and contribute to drowsiness.

Glucose Utilization:

Your brain primarily relies on glucose for energy. After consuming sugary foods, your body prioritizes the metabolism of glucose, which can temporarily decrease the availability of glucose for other bodily functions, including mental alertness. This can make you feel sleepy as your brain’s energy supply is redirected.

Hormonal Response:

Sugar consumption can affect the secretion of various hormones, including cortisol and adrenaline. Initially, these hormones may increase alertness and energy levels. However, the subsequent drop in blood sugar levels can trigger the release of hormones like cortisol, which plays a role in regulating stress and energy metabolism. Increased cortisol levels can contribute to feelings of fatigue and sleepiness.

Inflammation and Immune Response:

Excessive sugar consumption can lead to inflammation in the body. Chronic inflammation has been linked to conditions such as obesity, diabetes, and metabolic syndrome, all of which can contribute to feelings of fatigue and lethargy.

Gut-Brain Axis:

Emerging research suggests a strong connection between the gut and the brain. Consumption of sugary foods can alter the composition of gut microbiota, potentially influencing mood and behavior. Imbalances in gut bacteria have been associated with conditions like depression and fatigue.

Individual Variations:

It’s essential to recognize that individual responses to sugar can vary based on factors such as genetics, overall diet, lifestyle, and existing health conditions. Some people may be more sensitive to fluctuations in blood sugar levels, leading to more pronounced feelings of fatigue after consuming sugar.

Feeling sleepy after eating sugar is a complex interplay of physiological and biochemical responses. If you feel like taking an afternoon nap after experiencing a sugar crash, consider using a sleep aid like a weighted blanket for better sleep. Our Cotton Napper, for instance, is a chunky-knit gently weighted blanket to help you fall asleep faster and feel calmer, naturally.

Next, let’s consider some frequently-asked questions about post-sugar sleepiness, starting with whether or not this is a symptom of insulin resistance.

Is Falling Asleep After Eating a Sign of Diabetes?

Falling asleep after eating, especially if it’s a recurrent pattern, can potentially be a symptom of diabetes, but it’s not necessarily a definitive sign on its own. Here’s why:

  1. Postprandial Hypoglycemia: In some cases, falling asleep after eating may be a result of postprandial hypoglycemia, which is when blood sugar levels drop too low after a meal. This can happen in individuals with diabetes, particularly those who take insulin or certain medications that lower blood sugar levels. However, postprandial hypoglycemia can also occur in people without diabetes due to various reasons such as excessive insulin release or insulin resistance.
  2. Insulin Resistance and Fatigue: Insulin resistance, a hallmark of type 2 diabetes, can lead to difficulty in glucose uptake by cells, resulting in high blood sugar levels. Despite high blood sugar, cells may not receive adequate energy, leading to feelings of fatigue and lethargy after eating.
  3. Other Diabetes Symptoms: Falling asleep after eating may be accompanied by other symptoms of diabetes, such as increased thirst, frequent urination, unexplained weight loss, blurred vision, or tingling sensations in the hands or feet. These symptoms are more concerning when they occur together with postprandial drowsiness.

It’s essential to consider other factors that can cause post-meal drowsiness, such as consuming a large meal, eating foods high in carbohydrates or fats, or simply being tired. Also, certain medical conditions unrelated to diabetes, such as sleep disorders or gastrointestinal issues, can contribute to postprandial sleepiness.

Next, let’s look at whether or not you should entertain the thought of sleeping if you’re experiencing a sugar crash.

Should I Sleep After A Sugar Crash?

Deciding whether to nap after experiencing a sugar crash depends on various factors, including individual preferences, daily schedule, and overall health. Here are some benefits and disadvantages to consider:

Benefits of Napping After a Sugar Crash:

Also known as a “food coma”, sleeping after having a carb-heavy meal could have the following advantages:

  1. Rest and Recovery: Napping can provide an opportunity for rest and recovery, allowing your body to recharge and replenish energy levels depleted by the sugar crash.
  2. Improved Cognitive Function: Short naps, known as power naps, have been shown to enhance cognitive function, including alertness, memory, and concentration, which may help counteract the mental fog often associated with post-sugar fatigue.
  3. Stress Reduction: Napping can help reduce stress levels and promote relaxation, allowing your body to better cope with the physiological and psychological effects of the sugar crash.
  4. Enhanced Mood: A brief nap can improve mood and emotional well-being, helping to alleviate feelings of irritability or mood swings that may accompany a sugar crash.

Downsides of Taking a Post-Sugar Nap:

On the other hand, here’s why you should steer clear of napping if you feel tired after eating sweet foods:

  1. Disrupted Sleep Patterns: Napping too close to bedtime or for too long may disrupt your regular sleep patterns, making it more challenging to fall asleep at night and potentially worsening sleep quality overall.
  2. Delayed Productivity: Depending on the length of your nap and your body’s response, you may experience grogginess or sleep inertia upon waking, which can temporarily impair cognitive function and delay productivity.
  3. Dependence on Napping: Relying on naps as a coping mechanism for sugar crashes may mask underlying issues related to diet, lifestyle, or sleep habits, preventing you from addressing the root cause of the fatigue.
  4. Potential Overconsumption of Sugar: Napping after a sugar crash without addressing the underlying dietary factors may perpetuate a cycle of energy highs and lows, leading to repeated sugar cravings and subsequent crashes.

If you feel overwhelmingly fatigued and believe a nap would help you feel more refreshed and alert, a short nap may offer temporary relief. You can also take a coffee nap instead for an extra boost in energy. But… if you choose to stay awake, there’s several things you can try to ensure you maintain high energy levels. Let’s look at these in the next section.
