Heavy & Light Sleepers: How to Sleep Better
Sleep is the foundation of everything, but not everyone sleeps the same way. Do you need an alarm clock loud enough to rattle the windows? Or are you jolted awake by the sound of a pin dropping? Understanding whether you're a light or heavy sleeper can help you make sense of your sleep patterns, leading to a better night’s rest. This guide explores what it means to be a light or deep sleeper and why we sleep the way we do so you can improve your sleep health.
the sleep summary
Light sleepers spend more time in REM sleep, leading to frequent wake-ups and daytime tiredness.
Heavy sleepers experience long periods of deep sleep and may struggle with waking up on time.
Both sleep types can affect overall sleep quality and health, but understanding your sleep type can help you make adjustments for better rest.
You can change how you sleep by adjusting your sleep environment, investing in an alarm for deep sleepers or reducing noise to prevent wake-ups.
what is a light sleeper?
A light sleeper spends more time in rapid eye movement (REM) sleep, the stage where dreaming happens. REM sleep is vital for memory and learning, but because it's a lighter stage of sleep, it's also easier to wake up from. Common traits of a light sleeper include:
Waking up frequently during the night
Being easily disturbed by noise, light or movement
Remembering dreams vividly due to longer REM cycles
Light sleepers often struggle with interrupted rest, leading to daytime tiredness. Even if they get the recommended 7 to 9 hours of sleep, frequent wake-ups can leave them feeling groggy.
what is light sleep?
Light sleep is often considered to be the transitional period between being awake and deeper, more restorative sleep. This is also usually the period during which sleepers are the easiest to wake. REM is also considered a stage of light sleep compared to stage 2 and 3, which are deeper stages of slumber.
what is a deep sleeper?
A deep sleeper experiences long, uninterrupted periods of deep sleep, also known as slow-wave sleep. This is the most restorative sleep stage, when the body repairs itself, muscles relax and energy is replenished. These heavy sleepers often:
Sleep through alarms, conversations and even loud noises
Need multiple wake-up calls in the morning
Often wake up feeling well-rested, but may struggle with grogginess if they oversleep
While deep sleep is beneficial, heavy sleepers can find it difficult to wake up on time, especially if their alarm isn’t strong enough to break through their sleep cycles.
why do we become light or deep sleepers?
Your sleep type is partly genetic, however brain wave activity also plays a role. Light sleepers have more frequent bursts of brain activity, while deep sleepers experience longer stretches of deep, undisturbed sleep. But your surroundings can shape your sleep habits too. A noisy neighbourhood, irregular work hours or stress can train your body to be a light sleeper. On the other hand, a quiet, dark and consistent sleep schedule encourages deeper rest.
the science behind our sleep
As research advances, we’re starting to develop a deeper understanding of what happens when we go to bed and this includes learning about different types of sleep. A study from PNAS found that there is some evidence that enzymes found in the body and products we consume can affect the strength and duration of deep sleep in the body. The build-up of these enzymes may influence how sleepy we feel at night and how long we sleep for.
Specifically, stimulants like caffeine can impact your ability to fall asleep. To find out more, check out our guide explaining the true effects of caffeine on sleep.
can you change how heavily you sleep?
The way you sleep isn’t entirely fixed and your habits, environment and lifestyle all play a role. Adjusting your sleep patterns can improve how you feel in the morning. With the right changes, you can encourage deeper rest or make waking up easier, depending on what you need.
how to stop being a light sleeper
While light sleep is a natural part of the sleep cycle, too much of it can leave you feeling unrested. Strengthening your sleep routine and optimising your bedroom can help you transition into deeper, more restorative sleep. Sleep deeper with these top tips:
Use blackout curtains to block out light
Try a white noise machine or fan to mask sudden sounds
Stick to a consistent sleep schedule, even on weekends
Avoid caffeine and screens before bed
Try relaxation techniques like meditation or deep breathing
how to stop being a deep sleeper
While getting plenty of slow-wave sleep is great for your body, being overly deep in slumber can make waking up on time feel impossible. Training your body to wake up more naturally and adjusting your habits can help you rise more easily. Wake up more easily with these strategies:
Use an alarm with gradually increasing volume or a vibrating alarm under your pillow
Let natural light in, sunlight helps reset your body clock
Place your alarm across the room to force yourself out of bed
Keep naps short (20 to 30 minutes) to avoid grogginess
Try sleep cycle alarms that wake you at a lighter stage of sleep
If you struggle with grogginess, drink water and get moving as soon as you wake up
Whether you sleep like a log or wake up at every sound, understanding your sleep type can help you make changes for better rest. Light sleepers can focus on creating a peaceful environment, while heavy sleepers can work on waking up with ease. Small adjustments can lead to nights of deeper sleep and mornings that feel easier, because sleep should leave you feeling refreshed, not frustrated. Interested in learning more about sleep stages?
