Why Is My Elderly Parent Sleeping More Than Usual? UK Medical Insights

Is It Normal for Older Adults to Sleep More?

Find YOUR ideal care home NOW!

Ageing affects the structure of sleep. Older adults typically experience lighter sleep, wake more frequently during the night, and may go to bed earlier than they did in midlife. It is also common for seniors to nap occasionally during the day, especially if night-time sleep is fragmented.

However, spending most of the day asleep, struggling to stay awake during conversations, or showing a sudden increase in daytime drowsiness is not considered a typical part of ageing. A noticeable change in sleep duration or alertness should always be viewed in context. If the change is new, progressive or accompanied by other symptoms, it deserves medical evaluation.

Medical Causes of Excessive Sleeping in the Elderly

Excessive sleep in older adults, sometimes referred to as hypersomnia, is usually a symptom rather than a condition in itself. It often reflects an underlying issue that affects energy levels, mood or neurological function.

Depression is one of the most overlooked causes of excessive sleep in older adults. In later life, depression does not always present with visible sadness. It may instead manifest as persistent tiredness, social withdrawal and a lack of engagement in activities that once brought pleasure.

Neurological conditions such as dementia can also disrupt the body’s internal clock. Some individuals begin sleeping more during the day and become restless at night, creating a reversal of the normal sleep-wake cycle.

Medication is another common contributor. Many drugs prescribed in later life, including those for pain, anxiety or blood pressure, can cause drowsiness. Even small dosage adjustments can significantly alter energy levels.

Infections, particularly urinary tract infections, may present atypically in older adults. Rather than fever or pain, the first signs may include sudden fatigue and increased sleep.

Psychological and Social Factors

Beyond medical conditions, emotional and environmental factors can influence sleep duration. Loneliness, reduced daily stimulation and loss of routine can gradually increase the amount of time spent in bed. Retirement, bereavement or reduced mobility may all contribute to a quieter lifestyle, which in turn encourages longer periods of rest.

In some cases, excessive sleep reflects emotional withdrawal rather than physical illness. An elderly person who feels isolated or disconnected may unconsciously retreat into sleep as a coping mechanism.

When Should Families Be Concerned?

Concern is warranted when there is a noticeable and sustained change in sleep patterns, particularly if it develops over weeks rather than years. Sudden lethargy, confusion, weakness, appetite changes or behavioural shifts should prompt a GP consultation without delay.

If excessive sleep is accompanied by breathlessness, chest discomfort, persistent confusion or signs of infection, urgent medical assessment is advisable.

Monitoring patterns can be helpful. Observing how many hours are spent sleeping, whether night-time sleep is disrupted and whether alertness improves during engaging activities provides useful information for healthcare professionals.

Supporting Healthy Sleep in Older Adults

Encouraging structured daily routines can help regulate sleep. Exposure to natural daylight, light physical activity suited to ability, and social interaction all support a healthy circadian rhythm. Reviewing medication with a GP ensures that unnecessary sedative effects are not contributing to fatigue.

Most importantly, families should avoid dismissing excessive sleep as “just old age.” Changes in sleep often provide early clues about broader health issues. Early investigation can prevent complications and support a better quality of life.

FAQ – Excessive Sleeping in the Elderly

Is it normal for an 80-year-old to sleep most of the day?

Sleeping most of the day is not typically considered normal ageing. While older adults may nap more frequently, persistent daytime sleeping combined with reduced engagement should be assessed by a GP.

Can dementia cause excessive sleeping?

Yes. Dementia can disrupt the body’s internal clock and lead to increased daytime sleep and night-time wakefulness. Changes in sleep are common as cognitive decline progresses.

Should I take my parent to the GP for sleeping too much?

If there is a noticeable change in sleep habits, especially if it appears suddenly or is accompanied by other symptoms such as confusion or weakness, a GP appointment is recommended.

Can depression make elderly people sleep more?

Depression in older adults often presents as fatigue, withdrawal and increased sleep rather than visible sadness. It is a common but treatable cause of excessive sleeping.

What tests might a doctor perform?

A GP may review medication, order blood tests to check thyroid or metabolic function, assess for infection, and evaluate cognitive or mood changes depending on the symptoms presented.
