Have you ever struggled to stay alert while working in the afternoon or felt like you could nap anywhere? 

Even though this condition, called excessive daytime sleepiness, or others may refer to it as daytime somnolence, is not a disorder per se, it may be a sign of something more critical like poor sleep habits, stress, or other underlying health conditions. While occasional fatigue is normal, consistent drowsiness tells you something more important must be taken seriously. 

Continue reading our article to learn more about excessive daytime sleepiness and how to tackle this issue to regain energy, productivity, and overall quality of life. 

What is Excessive Daytime Sleepiness?

Before diving into solutions, we need to address this condition. Excessive daytime sleepiness is, by definition, difficulty staying alert or awake during the day, even when you should be fully engaged, like driving, working, and so on. Though most people must have experienced it sometimes after a late night or short sleep, this condition is considered if it happens almost every day for a minimum of 3 months. 

So, how is this condition different from general tiredness or fatigue? Fatigue often refers to physical or mental exhaustion that does not necessarily mean you cannot fight to keep your eyes open. Excessive daytime sleepiness, on the other hand, involves a strong and sometimes uncontrollable urge to sleep regardless of how much sleep you have at night.   

Signs and Symptoms of Excessive Daytime Sleepiness

Besides being sleepy during the daytime for no reason, excessive daytime sleepiness can manifest in various ways. Here are some common signs and symptoms you also need to watch out for: 

• Persistent feelings of drowsiness: As the name suggests, you may not feel ‘fully awake’ and struggle to shake off the grogginess throughout the day, even after what feels like a full night’s sleep.
• Struggling to stay awake during daily activities: Many people have difficulties keeping their eyes open when watching TV or attending meetings, but they can easily fight it off. However, if you can’t, or worse, it occurs while driving, it signals a dangerous manifestation of excessive daytime sleepiness. 
• Difficulty concentrating: Excessive daytime sleepiness often impairs one’s ability to focus, which can affect productivity and overall decision-making. Over time, this symptom can make it difficult to manage daily responsibilities. Hence, if you experience any of these symptoms, addressing them must be your first priority. 
• Experiencing “micro-sleeps”: Microsleeps are those moments when you feel like you’re out for a few seconds without warning. During these moments, you may appear awake to others. Still, your brain essentially “snoozes,” significantly impairing your ability to process external information.
• Physical symptoms: Other symptoms that may also appear are persistent yawning, low energy levels, sluggishness, and even irritability or other mood disturbances. These symptoms may seem harmless compared to others, but leaving them unaddressed may lead to a gradual decline in the ability to function effectively. 

Common Causes of Excessive Daytime Sleepiness

Sleep Disorders

Disorders affecting the quantity and/or quality of sleep are the most common causes of excessive daytime sleepiness. Sleep apnea, for example, involves brief interruptions of breathing or apnea, fragmenting the sleep cycle and leaving people tired even after enough sleep. Similarly, the infamous insomnia, which involves difficulty falling or staying asleep, may result in chronic sleep deprivation.

Another main culprit, or should we say one of the extreme ones, is narcolepsy. This neurological condition disrupts the brain’s ability to regulate the sleep-wake cycle, meaning you can experience an uncontrollable ‘sleep attack’ that can strike any moment without warning.

Poor Sleep Habits

Irregular sleep schedules, such as inconsistent bedtimes or wake-up times, can throw off your body’s sleep/wake cycle and make it harder to get quality rest. Similarly, overusing electronic devices emitting blue light can trick your mind into thinking that it’s not time to sleep yet, suppressing melatonin, a hormone crucial for regulating sleep. Any of these habits can significantly impact your sleep quality and leave you feeling drowsy the next morning. 

Lifestyle Factors

Leading an active lifestyle through exercise is known to reduce the time it takes to fall asleep for many people and even alleviate daytime sleepiness for some. That’s why it’s no surprise that lack of physical activity is doing the opposite. Additionally, a poor diet, combined with excessive consumption of alcohol or caffeine, can disrupt sleep quality. Caffeine helps you stay alert, obviously, while alcohol, though considered a sedative, prevents you from reaching a deeper stage of rest.

Medical Conditions

Lastly, underlying medical conditions can indirectly disrupt overall sleep quality. Thyroid disorders, both overactive and underactive, can cause faster heartbeat, muscle weakness, and night sweats, while hypothyroidism causes muscle pain and trouble tolerating colds. Another chronic condition is chronic fatigue syndrome, which, as the name implies, causes extreme fatigue and can also make it nearly impossible to stay alert during the day. 

Besides physical disease, we shouldn’t forget about mental conditions affecting sleep quality. Depression can manifest in two opposite ends of the spectrum: insomnia or oversleeping. Both, however, can disrupt the sleep pattern and eventually result in daytime drowsiness. Hence, seeking professional healthcare can help you identify the root cause of sleepiness and treat them accordingly. 

Steps to Take if You’re Experiencing Excessive Daytime Sleepiness

1. Assess Your Sleep Habits

Excessive daytime sleepiness doesn’t necessarily mean you have a sleep disorder. Most of the time, the problem stems from your sleep routine and environment. So, start by asking yourself, ‘Are you going to bed and waking up at consistent times?’ and ‘Is your bedroom quiet, dark, and comfortable enough?’ 

2. Create a Sleep-Conducive Environment

Your bedroom plays a huge part in restful, uninterrupted sleep. The simplest thing you can do is to keep it quiet, dark, and cool. Although not everyone is blessed with a quiet neighborhood, a blackout curtain and earplugs may help minimize the external lights and noise. Next, things that often get overlooked are mattresses and pillows. Little does anyone know, however,  that an uncomfortable bed can mess with your sleep cycle in the long run. 

3. Evaluate Your Diet and Lifestyle

Think about your lifestyle and whether or not you have limited screen time before bed.  You should also reflect on your level of physical activity during the day and consume anything that can lower your sleep quality, like caffeine, alcohol, or heavy meals close to bedtime. Regardless of which is the main culprit to your excessive daytime sleepiness, modifying your lifestyle to a more balanced one will benefit your overall health and well-being.

4. Seek Professional Help

If you have tried to improve your sleep habits, environment, and lifestyle, but nothing seems to help, it’s time to seek professional help. The constant drowsiness could be a sign of the underlying sleep disorder we talked about earlier. With the help of professionals at The Sleep Center at Wellness Institute of Sleep and Health (WISH), you can get a test like a sleep study to identify the root cause of your symptoms and address the condition with appropriate interventions. 

Treatment Options for Excessive Daytime Sleepiness

• Lifestyle Adjustments: Begin with improving your daily habits, such as maintaining a consistent sleep schedule, engaging in regular physical activity, reducing caffeine and alcohol consumption, and optimizing your sleep environment. These foundational changes can significantly enhance sleep quality and your well-being in general. 
• Medical Treatments: Continuous positive airway pressure (CPAP) therapy is often recommended for sleep disorders like sleep apnea to keep airways open during sleep. Meanwhile, your doctor may prescribe a stimulant drug to help you awake during the day and prevent sleep attacks for narcolepsy. 
• Sleep Coaching and Support: Some individuals benefit from working with a sleep coach or participating in support groups. These resources provide personalized strategies, accountability, and encouragement to help manage excessive daytime sleepiness effectively.
