Excessive Sleeping During the Day - Is it a Sleep Disorder?

A good night’s sleep, healthy diet, fresh air, and drinking clean water every day are essential ingredients to a healthy happy life. When one or more of these elements is disturbed, it can affect your physical health and mental wellbeing.  

Sleep disorders such as insomnia, hypersomnia, sleep apnea, narcolepsy, etc. steal quality rest and exacerbates current illnesses. If you’re taking many day time naps, having difficulty sleeping at night, and experiencing excessive sleepiness during your waking hours, you could be suffering from a sleep disorder. Let’s talk about excessive sleeping, what it means, and how you can get better sleep tonight.  

Why Do We Need Sleep? 

Sleep is essential to a healthy mind and body. Sleep deprivation research has shown that lack of sleep makes people emotionally volatile, irritable, short tempered, and ill. As you sleep, your body goes into repair mode, recharging your energy, building muscle, storing memories, replenishing hormone levels, and fighting any illness. 

Any disruptions to your sleep schedule cause an imbalance in your system and puts pressure on your central nervous system. You become exhausted, unable to focus on work or daily tasks, become short tempered with loved ones, and crave more sugar to get you through the day.

Possible Symptoms of Daytime Somnolence:

That said, there is such thing as getting too much sleep, and drowsiness during the day can affect your health, productivity, and quality of life. A few signs of somnolence (excessive sleepiness) and hypersomnia (excessive daytime sleepiness) include: 

  • Yawning throughout your waking hours
  • Headaches
  • Feeling agitated for no reason
  • Restlessness and irritability 
  • Being short tempered with loved ones 
  • Difficulty concentrating or learning new skills 
  • Eating more sugary foods or lack of appetite

Is Sleeping During the Day Bad? 

Your circadian rhythm is dictated by light and darkness, seeing the sunlight peer through your curtains in the morning alerts your system to ‘wake up’. As dusk descends in the evening, you begin to feel sleepy and prepare for your 8 hours of sleep. Fighting this natural rhythm has detrimental effects on physical health. If you are awake all night and sleeping during the day, you may find your natural immune defense is low and you’re picking up colds and flu quicker than normal. Your blood pressure, blood sugar levels could be at unhealthy levels, and your metabolism might be slow, so you’re gaining weight. If you have trouble sleeping at night, tired but cant sleep at night, and sleeping a lot during day time hours, you could have a sleep disorder or other medical condition. The occasional day time nap is not harmful but sleeping during the day effects hormone levels, tissues and organs don’t receive their messages and illness ensues, such as diabetes and obesity.
