Why Do I Feel Excessively Sleep

You may feel sleepy and fatigued for many reasons, including weather changes, depression, sleep disorders, side effects of medications, and underlying conditions like thyroid disorder and cancer.
The key to overcoming excessive sleepiness is to determine its cause. A healthcare professional may help you explore other symptoms, possible causes, and next steps to boost your energy and alertness levels.

What is excessive sleepiness?
Excessive sleepiness may mean different things for different people. In general, it may involve sleeping more hours than usual and feeling sleepy most of the day.

Unlike fatigue, which is more about low energy, excessive sleepiness may interfere with your school, work, and possibly even your relationships and day-to-day functioning. You may feel distracted and confused throughout the day, just like you may typically feel right after waking up.

What causes excessive sleepiness?
Daytime sleepiness may not be the only symptom you experience. Others may include snoring, restlessness, or kicking while you’re asleep. You may not be aware of some of these symptoms. For many people with sleep disorders, it may be a room partner who observes some of them.
Some causes of excessive sleepiness may not be related to disturbances in the sleep-wake cycle, but could also lead to feeling sleepy during the day. For example, a thyroid disorder or cancer.

Here are a few common causes of excessive sleepiness:
Sleep apnea
Sleep apnea is a potentially serious condition in which you repeatedly stop and start breathing throughout the night. It may lead you to feel sleepy during the day.
Other sleep apnea symptoms may include:
• loud snoring and gasping for air while sleeping
• sore throat and a headache upon waking up
• attention and concentration challenges
• irritability
Sleep apnea may increase your chance of experiencing:
• high blood pressure
• heart disease
• type 2 diabetes
• obesity

Sleep apnea may cause excessive sleepiness because it keeps you from getting enough deep sleep. The types of sleep apnea are:
• Obstructive sleep apnea (OSA): This occurs when the tissue in the back of the throat relaxes
while you sleep and partially covers your airway.
• Central sleep apnea (CSA): This happens when the brain doesn’t send the right nerve
signals to the muscles that control your breathing while you sleep.
Restless legs syndrome
Restless legs syndrome (RLS) causes an uncontrollable and uncomfortable urge to move one or both of your legs.
RLS may make it difficult to fall and stay asleep, resulting in excessive sleepiness the next day.
Medication side effects

Some medications cause drowsiness and excessive sleepiness as a side effect. The list may include medications to treat:
• high blood pressure
• depression
• nasal congestion (antihistamines)
• nausea and vomiting (antiemetics)
• psychosis
• epilepsy
• anxiety
Other factors will also cause the feeling of sleepiness
