Sleep Hacks That Actually Work in Your 40s and beyond 😴
Struggling to get a good night's sleep? You're not alone and it's not just in your head.
From the moment we hit our 40s, sleep changes. You might find it harder to fall asleep, you wake up more often, or you feel exhausted even after what should have been a full night's rest. Sound familiar, well to many of my clients it is a regular discussion we have?
The good news?
There are simple, science backed changes you can make tonight that will genuinely improve your sleep no expensive gadgets or miracle supplements required. Although, if you're into that sort of thing the placebo will also help 🤣
Here are the sleep hacks that actually work.
1. 🌡️ Cool Your Bedroom Down
Your body needs to drop its core temperature to fall asleep and stay asleep. As we age, this thermoregulation becomes less efficient, which is one reason sleep gets harder after 40.
What to do:
Aim for a bedroom temperature of around 16–18°C
Use lighter bedding or a fan if needed. Sometimes the fan noise also helps to channel your concentration into a dropping off phase of sleep.
Try a warm bath or shower 1–2 hours before bed counterintuitively, this helps your body cool down faster afterwards
2. ☀️ Get Morning Light Within 30 Minutes of Waking
This is one of the most powerful (and free) sleep hacks available. Morning light resets your circadian rhythm your body's internal clock, which directly controls when you feel sleepy at night. I know not all countries have light in the morning all year around.
What to do:
Step outside within 30 minutes of waking up
Even on cloudy days, outdoor light is far more powerful than indoor lighting
Just 10–15 minutes makes a measurable difference
If you can't get outside, sit by a bright window
"One of my clients Sarah started walking the dog first thing in the morning instead of after breakfast. I personally wanted her to run however we settled for fast walking. Within a week she was falling asleep faster at night."
3. Create a Proper Wind-Down Routine (Start 60 Minutes Before Bed)
Your brain needs a signal that sleep is coming. Without a transition period, you're essentially asking your body to go from 100mph to zero instantly and that rarely works.
A simple 60-minute wind-down routine:
60 mins before bed: Turn off overhead lights, switch to lamps or warm lighting
45 mins before bed: Put your phone face down or in another room. Probably the hardest thing for those of you reading this article now.
30 mins before bed: Do something calming reading (a real book, yes one you can actually turn pages 🤣), gentle stretching, or light journalling
15 mins before bed: Get into bed, keep the room dark and quiet
4. 📱 The Phone Rule That Changes Everything
Blue light from screens suppresses melatonin — the hormone that makes you sleepy. But it's not just the light. Scrolling through social media, reading news, or checking emails keeps your brain in an alert, problem-solving state right when it needs to be winding down.
What to do:
Set a hard rule: no screens 45–60 minutes before bed
Use your phone's "Do Not Disturb" or "Sleep Mode" feature
Charge your phone outside the bedroom if possible
If you must use your phone, switch to night mode and reduce brightness
5. ☕ Watch Your Caffeine Cut-Off Time
Caffeine has a half-life of around 5–7 hours, meaning if you have a coffee at 3pm, half of that caffeine is still in your system at 8–10pm. For many people over 40, caffeine sensitivity increases, making this even more impactful.
What to do:
Set a caffeine cut-off of no later than 1–2pm
Remember hidden caffeine sources: tea, fizzy drinks, chocolate, and some medications
Switch to herbal teas in the afternoon, chamomile, valerian root, and passionflower are all associated with better sleep
6. 🧘 Try the 4-7-8 Breathing Technique
This simple breathing exercise activates your parasympathetic nervous system, essentially your body's "rest and digest" mode. It's particularly effective if you lie awake with a busy mind. It may sound weird but all top athletes us these every day to reduce heart rate and enter relaxation pre bed.
How to do it:
Inhale quietly through your nose for 4 seconds
Hold your breath for 7 seconds
Exhale completely through your mouth for 8 seconds
Repeat 3–4 times
Many people report falling asleep before they even finish the second or third cycle. It sounds almost too simple — but the science behind it is solid.
7. 🍷 Rethink That Nightcap
Many people over 40 use a glass of wine or beer to "wind down" before bed. And while alcohol does make you feel sleepy initially, it significantly disrupts the quality of your sleep, particularly your REM sleep, which is the restorative deep-sleep stage. I am still shocked and how many of my own clients drink regularly, even though they know how toxic it is.
What actually happens when you drink before bed:
You fall asleep faster initially
But you wake up more frequently in the second half of the night
Your REM sleep is suppressed
You feel groggy and unrefreshed in the morning
What to do:
Try to stop drinking alcohol at least 3 hours before bed
Replace the evening drink with a warm herbal tea ritual instead
If you're using alcohol to manage anxiety or stress, that's worth exploring with your therapist/ psychiatrist or you could try your GP but don’t be surprised if they immediately try to medicate you to get you out the door. So try your health and fitness coach or therapist before seeing your GP.
8. 🛏️ Only Use Your Bed for Sleep (and S*x)
This is a well-established principle from Cognitive Behavioural Therapy for Insomnia (CBT-I). If you work in bed, watch TV in bed, or scroll your phone in bed, your brain starts to associate your bed with wakefulness and stimulation, the opposite of what you want.
What to do:
Keep all screens, work, and eating out of the bedroom
If you can't sleep after 20 minutes, get up and do something calm in low light until you feel sleepy then return to bed
Over time, your brain will relearn that bed = sleep
9. 💊 Consider Magnesium
Magnesium is one of the few supplements with genuine evidence behind it for sleep. Many adults particularly those over 40 are deficient in magnesium, and low levels are associated with poor sleep quality and restless legs.
What to do:
Consider a magnesium glycinate or magnesium threonate supplement (these forms are best absorbed)
Take it 30–60 minutes before bed
Alternatively, eat magnesium-rich foods: dark leafy greens, pumpkin seeds, almonds, dark chocolate, and bananas
Always check with your health and fitness coach and private nutritionist before starting supplements, especially if you take medication.
10. 📓 The 5-Minute Brain Dump
One of the biggest barriers to sleep for people in their 40s is a racing mind — running through tomorrow's to-do list, replaying conversations, or worrying about things you can't control at 11pm.
What to do:
Keep a notebook by your bed
(am a big advocate of this, I do this every night)
Before you start your wind-down routine, spend 5 minutes writing down everything on your mind tasks, worries, ideas, reminders
Once it's on paper, your brain can "let go" of the need to keep recycling those thoughts
Some people also find writing 3 things they're grateful for helps shift their mental state before sleep
Quick-Reference Sleep Checklist ✅
Here's your simple daily checklist for better sleep:
Get outside within 30 minutes of waking
No caffeine after 1–2pm
Stop alcohol at least 3 hours before bed
Begin wind-down routine 60 minutes before bed
No screens 45 minutes before bed
Cool bedroom to 16–18°C
Do the 4-7-8 breathing in bed
Keep a notepad for brain dumps
Only use bed for sleep and if your lucky enough S*x also.
The Bottom Line
Better sleep after 40 isn't about a miracle pill or an expensive mattress (though a good mattress helps!). It's about consistent small habits that work with your body's natural rhythms rather than against them.
Pick just two or three of these hacks to start with this week. Don't try to implement everything at once. Small, sustainable changes compound quickly and within a week or two, you could be sleeping better than you have in years.
If you would like a true change to your lifestyle and fitness.
