Everything You Need to Know About Sleeping Better Later in Life

When retirement rolls around, it’s one of life’s little luxuries: no alarms and no early morning starts if you’re not feeling it. Yet for many, that freedom brings a new struggle with sleep. What once came easily after a long, hard day of work, now feels stubbornly out of reach. 

This guide is for those quiet evenings spent staring at the ceiling, wondering why your body won’t switch off. We’ll walk you through why getting a good night's sleep is so important, how much you need, what might be disrupting it and easy ways you can reclaim your nights. 

Your Sleep Cycle Simplified 

The sleep cycle is a complex and fascinating topic that can be hard to understand at first. But put simply, it’s made up of two main types of sleep: non-rapid eye movement  (non-REM) sleep and rapid eye movement (REM) sleep. 

Non-REM sleep is made up of three stages whereas REM sleep is a single phase in itself. 

1. Light Sleep ( stage 1 & 2 of non-REM sleep)

• This is the “drifting off” stage and the start of real rest.

• Your heart rate slows down, muscles relax and body temperature drops. 

• You still wake up easily at this stage. 

2. Deep Sleep (stage 3 of non-REM) 

• This is the most restorative stage for your body. 

• Your tissues repair, energy is restored and your immune system gets a boost.

• Waking up during this stage can often leave you feeling groggy. 

3. REM Sleep 

• The brain is active and you’ll often dream in this stage.  

• REM sleep is important for memory, learning and emotional health 

• Your body’s relaxed but your brain is busy processing information 

Why Sleep Matters Even More as We Age 

Sleep is your body’s time to repair, recharge and restore itself by focusing on things like:

• Brain health: during deep sleep and REM sleep, your brain processes memories, clears out waste and supports problem solving skills. Poor or disrupted REM sleep has been linked to a higher risk of dementia. 

• Physical health: sleep helps regulate blood pressure, supports immune functions, repairs muscles and tissues and balances hormones. 

• Mood: quality sleep keeps irritability, anxiety and low mood in check, and helps you handle daily stress. 

• Healthy ageing: consistent, good-quality sleep is associated with sharper thinking skills and better mobility 
  
  

How Much Sleep Do You Really Need? 

The NHS and sleep specialists recommend older adults  getting between 7-9 hours every night. This is about the same as younger adults because your need for sleep doesn’t decrease with age, even if your routine or lifestyle change. 

• Aim for 7-8 hours most nights which is enough to go through several full sleep cycles (light sleep, deep sleep, REM) for full restoration.

• Quality matters just as much as quantity so if you’re waking often, not spending a lot of time in deep or REM stages or waking up not feeling well-rested then these can be signs of poor quality sleep, even if you’re in bed for 8 hours. 

• Oversleeping regularly (more than 9 hours) can sometimes be linked to underlying health conditions and is worth discussing with your GP. 

What Disrupts Sleep in Later Life?

Several factors can affect at your ability to get deep, restorative sleep:

• Changes to your natural body clock: with age, we can often feel sleepier in the evening and wake up throughout the night or in the early morning which can lead to fragmented sleep. 

• As we age, the amount of time we spend in REM and deep sleep decreases, so sleep becomes lighter and more easily disrupted by noise, light, or movement.

• Medical conditions, chronic pain, heartburn or needing the toilet at night can all contribute to disturbed sleep too. 

• Using or looking at screens, like your mobile, tablet or laptop can make it harder to fall asleep because the blue-light from these devices can affect the levels of melatonin (an important sleep hormone) in your body which can make it harder to fall asleep

• External factors like street noise, light from electronics that haven’t fully been switched off or a room that’s too hot or cold can stop you from reaching or staying in deep or REM sleep.

How to Optimise Your Sleep 

Here are some simple changes that can make a big difference to your sleep quality:

• Keep a regular sleep schedule: go to bed and wake up at roughly the same time everyday, even weekends to help set your body clock or circadian rhythm. 

• Make your bedroom sleep-friendly : keep it cool, quiet and dark by investing in a pair of blackout curtains or blinds, get rid of ticking clocks or use earplugs and eyemasks if you prefer. 

• Wind down with a relaxing routine: spend the last 30-60 minutes of your day winding down with a cup of calming chamomile or lavender tea for instance with some light reading or perhaps a short stroll in your back garden. 

• Stay active during the day: gentle movement like walking, swimming, even gardening during the day, can help you fall asleep faster and enjoy a good night’s sleep. 

• Nap wisely: short naps, lasting between 20 to 30 minutes, early in the day can help you feel more alert without affecting nighttime sleep and are much better than long naps taken later in the day. 

• Watch what you eat or drink: avoid caffeine after midday and opt for lighter evening meals to avoid discomfort or excessive bloating when you’re lying down. 

• Get the best bedding and sleepwear: breathable, lightweight fabrics  and supportive pillows and mattresses can make a big difference in keeping you comfortable through the night. 

• Get daylight exposure: natural sunlight in the morning helps lift your mood and sets your internal clock, improving your sleep-wake cycle. 

When To Get Help

If you’re having difficulty with your sleep, despite making changes, then it might be time to speak to your GP or carer (if you have one) for support with any of the following issues: 

• Regularly difficulty with falling or staying asleep 

• Daytime sleepiness that affects your daily life 

• Loud snoring, choking or gasping during your sleep 

• Any other serious sleep-related issues which you can’t seem to solve
