Medical reasons Why are you feeling sleepy all the time
                     Medical reasons: Why are you 
feeling sleepy all the time
Uncontrollable yawning, heavy eyelids and the powerful urge to doze 
off during the day are signs of excessive sleepiness. Struggling to stay 
awake can drag down performance at school and work, put a strain on 
social and personal relationships, and create serious risks when driving.
If you experience persistent drowsiness, it’s normal to wonder, “why 
am I always sleepy?”
The most common causes of excessive sleepiness are sleep deprivation 
and disorders like sleep apnea and insomnia. Depression and other 
psychiatric problems, certain medications, and medical conditions 
affecting the brain and body can cause daytime drowsiness as well.
What is Excessive Daytime Sleepiness?
Excessive daytime sleepiness is a difficulty staying awake or 
alert1 when you need to. Many experts define EDS as 
distinct from fatigue2, which involves strong feelings of 
physical exhaustion, but the two conditions may overlap.
Some researchers refer to EDS as hypersomnia, which 
describes disorders of excess sleep. However, hypersomnia 
is a broader term that includes issues like sleeping too 
much at night that are distinct from extreme drowsiness 
during the day or in situations when alertness is required.
What Are the Causes of Excessive Daytime Sleepiness?
Excessive daytime sleepiness is not a condition in itself; 
instead, it is a symptom caused by an underlying problem.
Failure to Prioritize Sleep: Choosing to stay up late to watch 
a series or wake up early to go to the gym are examples of 
how sleep can get bumped down the list of priorities and 
crowded out of a busy schedule. This can cause drowsiness 
the next day, and the problem can accumulate over time. 
When these choices cause a lack of sleep over an extended 
period, it is known as insufficient sleep syndrome. 
Insomnia: This condition includes a range of problems that 
make it hard to fall asleep or stay asleep for as long as you 
want. Insomnia is often related to other sleep problems 
described here that give rise to excessive sleepiness.
Sleep Apnea: Obstructive sleep apnea (OSA) is a breathing 
disorder characterized by brief pauses in breathing during the 
night. It creates fragmented sleep that typically causes daytime 
drowsiness and may affect up to 20% of adults6. Central sleep 
apnea (CSA) is less common but can also cause disturbed sleep.
Restless Leg Syndrome (RLS): This condition causes 
a strong sensation of needing to move one’s 
extremities, particularly the legs, and is a known 
risk for disrupting total sleep time and sleep quality.
Circadian Rhythm Sleep-Wake Disorders: When a 
person’s sleep schedule is misaligned with their 
local day-night cycle, it can cause short and 
fragmented sleep. Examples include jet lag and 
sleeping problems among shift workers.
Poor Sleep Quality: Sleep insufficiency isn’t just about 
a low quantity of sleep; it’s also about sleep quality. 
People who don’t smoothly progress through sleep 
cycles may fail to get enough deep sleep or REM sleep. 
As a result, they may not wake up refreshed even if 
they sleep for the recommended number of hours.
Pain: Virtually any ailment that induces pain, including 
arthritis, fibromyalgia, or herniated disks, can 
complicate sleep and make a person prone to 
drowsiness during the day.
• Frequent Nighttime Urination: This condition, 
known as nocturia, involves needing to get up 
from bed during the night to pee and is 
estimated to affect8 up to one out of three 
older adults and one out of five younger 
people. 
• These are some of the reasons behind you 
feeling sleepy all the time.
