Sleep Problems After Stroke: Safe Positioning and a Calmer Night Routine

Sleep depends on the brain's body clock, on comfort, on mood and on a quiet body. A stroke can disturb several of these at once. The brain regions that regulate sleep and wake cycles may be affected directly. Time in hospital, with lights, noise and night-time checks, can reverse the day and night rhythm. After discharge, pain, stiffness, worry about the future and frequent trips to the toilet all interrupt sleep.

Poor sleep is not a minor complaint. It increases daytime fatigue, makes it harder to learn and repeat exercises, worsens mood and raises the risk of falls at night. For the family member who gets up repeatedly, it becomes a source of exhaustion that builds over weeks. Dealing with sleep deserves the same attention as dealing with walking or hand function.

• Difficulty falling asleep or waking at 3 or 4 a.m.: often linked with worry, low mood or pain.
• Day and night reversed: sleeping most of the day and being awake at night, common after long hospital stays.
• Waking to pass urine: see our guide on bladder and bowel control after stroke.
• Pain and stiffness: especially the shoulder, hip or the side that is weak or spastic.
• Restless legs: an urge to move the legs in the evening with uncomfortable sensations.
• Breathing pauses and loud snoring: possible sleep apnoea, described below.
• Confusion at night: more common in older people and after illness. It needs medical review if new.

In sleep apnoea, the airway repeatedly narrows or closes during sleep, so breathing pauses and the oxygen level dips. Studies show that it is common among people who have had a stroke, and some research links untreated apnoea with poorer recovery, although the relationship is not simple. It can also raise blood pressure, which is relevant to the risk of another stroke.

Families may notice loud snoring, gasping, long pauses followed by a snort, restless sleep, morning headaches, a dry mouth, or the person falling asleep during the day even after a long night in bed. If these signs are present, ask the doctor about a sleep study. Treatment, such as a breathing mask used at night, is arranged by the doctor, not by the physiotherapist. In the meantime, avoid sleeping flat on the back if snoring is worse in that position, and avoid sedatives unless a doctor has approved them.

The way the body lies for eight hours matters, especially when muscles cannot protect the joints. The aims are comfort, a protected shoulder, joints that are not left in a fixed bent position, and healthy skin. A physiotherapist should check what suits the individual, but these principles apply to most people:

• Lying on the unaffected side: place a pillow in front of the chest to support the weak arm so it is not hanging across the body, with a pillow between the knees and the weak leg slightly bent.
• Lying on the affected side: this can be useful for short periods because it keeps attention on that side and leaves the strong hand free, but only if there is no shoulder pain. Bring the shoulder forward rather than leaving the arm trapped behind, and support the trunk with a pillow.
• Lying on the back: put a small pillow under the weak shoulder and upper arm so the shoulder is not pulled backward, keep the arm slightly away from the body, and use a small towel roll under the weak hip if the leg rolls outward.
• Ankle and foot: a pillow or footboard to hold the foot near a right angle can help prevent the ankle from stiffening in a pointed position. Some people need a splint prescribed by the therapist.
• Knees: avoid keeping a pillow under the knees all night, every night, if the person lies flat most of the time, as this encourages the knees to stay bent.

Never pull on a weak arm to turn or lift someone. The shoulder joint is fragile after stroke. Our guide on bed mobility and transfers after stroke shows safer ways to roll and sit up.

If the person cannot turn independently, the skin over bones such as the hips, tailbone, heels, ankles and shoulder blades can break down within hours to days under constant pressure. Regular repositioning is the main protection. Many care plans suggest changing position about every two to three hours, but the right interval depends on the person's skin, mattress and nursing advice.

• Check the skin each morning and evening for redness that does not fade, blisters, or broken areas.
• Keep sheets smooth and dry. Wrinkles, crumbs and damp sheets add pressure.
• Use a pressure-relieving mattress if recommended, and keep the heels lifted off the surface with a pillow under the calves.
• Do not massage red areas. Relieve pressure and tell the nurse or doctor.

For more on this, read about pressure injury and contracture prevention.

If swallowing is affected, saliva or stomach contents can reach the airway, particularly when lying flat. Raising the head and chest slightly, using a wedge pillow or an adjustable bed, can help, and meals should end at least a couple of hours before bed. A speech and language therapist or doctor should advise on the right angle. If the person coughs or chokes at night, has a wet voice, or wakes with chest congestion, tell the doctor, because this may signal that food or liquid is going the wrong way.

A bed that is too low makes standing up difficult and one that is too high makes sitting on the edge unsafe. Ideally, when sitting on the edge, both feet should rest flat on the floor with hips and knees at about a right angle. A firm edge helps balance during the transfer. Bed rails can help some people turn but they carry a risk of entrapment, so use them only on professional advice.

For the layout, lighting and flooring of the room itself, see our guide on bedroom set-up for neuro rehabilitation at home. The sleep-related adjustments here complement that guide rather than repeat it.

• Keep fixed times for waking, meals and bed, including weekends.
• Get morning light and some activity. Sitting by a bright window or outdoors and doing therapy exercises earlier in the day help reset the body clock.
• Limit napping. If a nap is needed, keep it short and before mid-afternoon.
• Reduce caffeine in the afternoon and evening, including strong tea.
• Avoid heavy meals and large drinks just before bed, and use the toilet before sleeping.
• Wind down for an hour. Dim the lights, turn off the television, keep conversation calm and do familiar activities.
• Keep the room dark, quiet and at a comfortable temperature.
• Do not stay awake in bed for hours. If the person is wide awake, a short quiet activity in a chair may help before trying again.

Pain keeps many people awake, especially shoulder pain after stroke. Review the support of the arm described above, and read about shoulder pain after stroke (Arabic) if this is the problem. Gentle stretching and a warm shower or warm bath earlier in the evening may ease stiffness, but check the water temperature with the unaffected hand or elbow, because reduced sensation increases the risk of burns. Avoid hot-water bottles or heating pads on a limb with reduced feeling.

If spasticity or cramps wake the person, tell the doctor, since treatment options exist. Do not adjust muscle relaxants without advice.

In hot weather, overheating disrupts sleep, and people with limited movement cannot always throw off a cover. Use light cotton sheets, keep air moving in the room without a fan or air-conditioner blowing directly on the person, drink enough during the evening and watch the room temperature. A person with reduced sensation may not feel when they are too hot or too cold, so check from time to time.

It is tempting to ask for a sleeping tablet when nights are bad. Sedatives can cause morning drowsiness, confusion and falls, and some can worsen sleep apnoea or breathing. They should be used only when prescribed for the individual and reviewed. Never give someone else's tablets. If herbal or over-the-counter products are being considered, check with the doctor or pharmacist first, since some interact with stroke medicines such as blood thinners.

Many people who lie awake are going over fears about recovery, money, family roles or another stroke. Low mood and anxiety are common after stroke and respond to treatment, so sleep problems accompanied by tearfulness, hopelessness or withdrawal need attention. See depression and mood changes after stroke. If seizures are a concern at night, our guide on seizures after stroke or brain injury explains the safety steps.

Night-time care is one of the heaviest parts of the caregiving role. Share it if you can, even a few nights a week, use a simple baby monitor or bell instead of staying alert all night, set up a commode or urinal to reduce lifting, and rest when the person rests. Our guide on the family caregiver role after stroke has more on sharing the load.

• Assess how the person lies and moves in bed, and advise on positioning with pillows and supports.
• Teach safe rolling, sitting up and getting out of bed, and train the family to assist without injuring the shoulder or their own backs.
• Work on stiffness, spasticity and comfort through the day so nights are easier.
• Check the height of the bed and the route to the bathroom for safety.
• Notice signs such as pressure marks, snoring with pauses, or night confusion and pass them to the treating doctor.

• Loud snoring with pauses in breathing, gasping or severe sleepiness in the daytime.
• Red or broken skin that does not improve after pressure is relieved.
• New confusion or agitation at night, especially with fever or pain.
• Choking, wet coughs or chest congestion at night.
• Sleep problems with persistent low mood, hopelessness or thoughts of self-harm.
• New severe headache, weakness, speech or vision changes: this is an emergency.
