There are several factors to consider. In women 65+, the most common causes of daytime sleepiness are age-related changes that reduce deep, refreshing sleep; sleep apnea; side effects from medicines; health conditions like anemia, thyroid problems, diabetes, heart or kidney disease, and depression; and reduced daytime activity or light exposure. Important red flags, what to try at home, and when to see a doctor including how to screen for sleep apnea, adjust routines, and review medications are covered below and can shape the right next steps for your care.
If you've been asking yourself, "why am I so sleepy during the day?", you're not alone. Many women age 65 and older notice changes in their energy levels—even when they believe they're getting enough sleep at night. Daytime sleepiness is common, but it is not something to ignore, especially as we age.
Sleepiness during the day can affect memory, mood, balance, and overall quality of life. In some cases, it can also point to medical issues that deserve attention. Below are five common, medically recognized causes of daytime sleepiness in women 65+, explained clearly and calmly—without minimizing what matters.
As we get older, sleep naturally changes. Research from the National Institute on Aging shows that older adults often experience:
Even if you spend 7–8 hours in bed, your sleep may not be as refreshing as it once was.
Poor sleep quality can leave you feeling:
One of the most common and underdiagnosed reasons women ask, "why am I so sleepy during the day?" is sleep apnea.
Sleep apnea causes breathing to stop and start during sleep—often without the person realizing it. While commonly associated with men, postmenopausal women are at increased risk, especially after age 65.
Snoring may or may not be present.
Because sleep apnea increases the risk of heart disease, stroke, diabetes, and falls, it's important to take symptoms seriously. If you're experiencing unexplained daytime fatigue along with any of these symptoms, you can quickly check whether Sleep Apnea Syndrome might be contributing to your sleepiness using a free, AI-powered symptom checker designed to help identify potential causes.
If symptoms are present, speak to a doctor promptly, as sleep apnea is treatable and early care can make a meaningful difference.
Many women over 65 take medications to manage chronic conditions. According to data from the U.S. Food and Drug Administration and geriatric medicine studies, medication-related drowsiness is a leading cause of daytime sleepiness.
As we age, the body processes medications more slowly, which can increase side effects even at standard doses.
Several common medical conditions become more frequent after age 65 and can cause ongoing sleepiness during the day.
These conditions can reduce oxygen delivery, alter metabolism, or disrupt sleep cycles—leading to persistent tiredness.
Daytime sleepiness caused by an underlying illness will not improve with more naps alone. If sleepiness is new, worsening, or affecting daily activities, it's important to speak to a doctor and ask whether blood tests or evaluations are appropriate.
Another overlooked reason women ask, "why am I so sleepy during the day?" is reduced activity.
Retirement, limited mobility, or chronic pain may lead to:
Daylight and movement help regulate your circadian rhythm—your internal sleep-wake clock. Without them, your body may not clearly distinguish day from night.
These changes can gently improve alertness without medications.
While many causes are manageable, some should never be ignored. Speak to a doctor promptly if daytime sleepiness is accompanied by:
These symptoms may signal conditions that require urgent medical care.
If you're wondering why am I so sleepy during the day, start by observing patterns:
Consider keeping a short sleep diary and bring it to your next medical appointment.
If you suspect your sleep quality may be disrupted by nighttime breathing issues, using a free Sleep Apnea Syndrome symptom checker can help you determine whether this condition might be worth discussing with your healthcare provider.
Daytime sleepiness is common in women 65+, but it is not something you have to live with. Causes range from normal aging changes to sleep disorders, medications, and medical conditions—some of which can be serious if left untreated.
Being informed is the first step. The next step is simple but essential: speak to a doctor about ongoing or worsening sleepiness, especially if it affects your safety, independence, or quality of life.
Good sleep supports healthy aging—and you deserve to feel awake, steady, and present during the day.
