Once you’re in bed and you’ve drifted off to sleep, there’s not much worse than suddenly waking up out of the blue and doing the dreaded, ‘how many hours of sleep do I have left before I have to get up?’ calculation. In this blog, we’ll look at some of the reasons you might keep waking up during the night and what you can do to manage it.

There are several things you can do to prevent multiple nightly wakeups. Try changing your habits for better sleep:

• Stop drinking caffeine after noon
• Limit alcohol and heavy meals close to bedtime
• Reduce fluids two hours before sleep

To try and prevent waking up in the first place, it is important to make your sleep environment as comfortable and relaxing as possible. Follow these simple tips to optimise your sleep environment:

• Keep your room cool, somewhere between 15 to 19°C is the recommended temperature.
• Make sure your room is dark and quiet. Use blackout curtains, an eye mask, or a white noise machine to block out disruptive light and sounds.
• Avoid checking your alarm clock or phone. Seeing the time can cause you anxiety and stress which will make both falling asleep and falling back asleep harder.

It typically means your sleep cycle is disrupted by physical stress, environmental factors or a health issue. Waking up briefly is normal but waking up fully numerous times over the course of a night is often a sign of an underlying issue.

• Stress of anxiety: Racing thoughts or an early morning spike in the stress hormone cortisol can ruin lighter sleep.
• Sleep apnea: Brief pauses in breathing force your brain to wake up just enough to open your airway.
• Blood sugar dips: A sudden drop in blood glucose overnight triggers adrenaline and cortisol, which wakes you up suddenly.
• Hormonal shifts: Changes in oestrogen, progesterone, or testosterone can cause hot flashes, night sweats, and restlessness.
• Needing the bathroom: Too much fluid consumption too close to bedtime or conditions like an overactive bladder or high blood sugar can cause frequent trips to the bathroom.
• Environment: A room that is too warm, not quiet or dark enough can disrupt sleep.
• Diet: Late-night alcohol and caffeine interfere with deep sleep, as well as heavy meals.

This isn’t usually a cause for concern and is something that a lot of adults deal with, so it’s important to not panic if you don’t always sleep through the night uninterrupted.

• Natural Sleep Cycles: Your brain goes through 90-minute sleep cycles. By the early morning hours, deep sleep fades and your body spends more time in light or REM sleep which makes it easier for a minor disruption to wake you up.
• Cortisol and Stress: Cortisol rises slowly around 2 AM to prepare your body to wake up. If you struggle with high stress or anxiety, your brain treats this normal hormone shift like an alert and jolts you awake in a state of panic.
• Blood Sugar Dips: If your last meal was eaten too early or was low in complex nutrients, your blood sugar can drop too low overnight. Your body then releases emergency hormones like adrenaline to raise glucose levels which wakes you up.
• Breathing disruptions: Sleep apnea or heavy snoring can disrupt sleep when oxygen levels dip during sleep cycles, waking you up fully by 3AM.
• Lifestyle habits: Drinking alcohol or eating heavy or spicy food near to bedtime impacts your sleep maintenance as your metabolism processes the food.
