Understanding the Science of Sleep
Before exploring techniques for how to wake someone up, it helps to understand the science behind sleep. There are several different stages of sleep that a person cycles through during a typical night - light sleep, deep sleep, and REM sleep. Each stage serves important restorative functions. As a sleep cycle nears the end, the body begins rising to a near-wakeful state before starting over.
Light Sleep
Light sleep comprises the first and second stages of a sleep cycle. During this phase, breathing and heart rate regulate, muscles relax, and body temperature drops. However, the brain still exhibits electrical activity similar to being awake. People are easily awoken during light sleep.
Deep Sleep
Stages three and four represent deep, slow-wave sleep. The body repairs tissues, builds bone and muscle, and strengthens the immune system during deep sleep. The brain uses less energy during this phase. It is very difficult to wake someone from deep sleep, which is why people often feel groggy if awoken in the middle of a sleep cycle.
REM Sleep
Rapid eye movement (REM) sleep is the dream stage. Though the body remains relaxed, the brain becomes more active. Heart rate, blood pressure and respiration increase to near waking levels. REM sleep is crucial for processing emotions, consolidating memories, and stimulating creativity. People can usually be awakened easily from this stage.
How to Wake Someone Up Gently
When attempting to wake someone up, the goal should be guiding them into light sleep for a more gentle transition. Here are some simple tips:
Gradually Increase Light
If waking someone up from a nap or overnight sleep, slowly turn on more lights in the room. The gradual increased brightness will simulate sunrise.
Play Relaxing Music
Soothing music in a volume that steadily rises helps ease someone awake without startling them. Instrumentals work best.
Gently Shake or Speak
If louder music does not do the trick, lightly shake the persons shoulder or softly say their name. This stimulation further guides their waking transition.
Open a Window
Letting in fresh outdoor air from a cracked window or fan can provide sensory stimulation to help rouse someone sleeping deeply. The temperature change and circulating air helps activate alertness.
How to Wake Someone Up Who is a Heavy Sleeper
Some techniques require a bit more intervention for those harder to awaken from deep slumber:
Use Smelling Salts
Ammonia inhalants provide a very potent odor that overwhelms the senses, making them useful for rousing unconscious people. However, take care not to directly expose nostrils.
Apply a Warm Compress
A warm washcloth applied to the chest, neck or forehead introduces an external heat stimulus that can penetrate deep sleep.
Gently Rub the Sternum or Earlobes
Massaging areas packed with nerve endings creates external nervous system stimulation to activate waking.
Spray Water on the Face
A light mist of water sprayed onto the face triggers a primitive response communicating the need to breathe, sputtering people even from very deep sleep.
Natural Remedies to Help Someone Wake Up
Certain dietary aids and medicinal scents can also assist rousing sleepers:
Coffee
Coffee is a widely used morning drink because caffeine blocks adenosine causing alertness. The smell alone can help kickstart wakefulness.
Peppermint Essential Oils
Peppermint contains menthol which triggers cold-sensitive nerves that relay awakening messages throughout the body including the brain.
Ginseng Tea
Ginseng has been used in Chinese medicine for centuries to stimulate energy levels. Compounds called ginsenosides promote alertness.
Ice Water with Lemon
The combination of cold temperature, lemon scent and tart citric acid sends signals to nerves that cause immediate physiological arousal.
Apps and Devices Designed to Awaken Sleepers
Specialized technologies provide customization tailored to each person's sleep stage patterns:
Sleep Cycle Alarm
This app uses sound analysis or movement data to monitor sleep cycles, waking the user during light sleep up to 30 minutes prior to a set alarm time.
Philips SmartSleep
The Philips SmartSleep system plays soft sounds determined to be soothing during deep sleep, then gradually dials up light and volume as your sleep stage shifts nearer to wakefulness.
Fitbit Alarms
Fitbit devices track heart rate, motion and sleep stages. Smart wake alarms go off when the tracker detects you are in light sleep within a preset timeframe.
Creating an Optimal Sleep Environment
Set the stage for more restful sleep and gentler waking by observing good sleep hygiene practices:
- Keep the room comfortably cool, quiet, and darkly lit
- Go to bed and rise at consistent times to set circadian rhythm
- Avoid using electronics before bedtime
- Limit caffeine, alcohol and large meals close to bedtime
- Do relaxing activities to unwind before bed like yoga, reading or meditation
Following healthy sleep regimen recommendations can make it easier to rouse someone sleeping deeply. However, persistent fatigue or difficulty waking may indicate an underlying condition needing medical attention.
FAQs
What is the best way to wake someone sleeping deeply?
The best method is to gradually increase light and sound, like opening blinds and playing gentle music that rises in volume. You can also rub their shoulder or arm, spray a water mist on their face, or waft smelling salts under their nose.
What scent is best for waking someone up?
Strong scents like coffee, essential oils like peppermint or eucalyptus, or smelling salts are most effective to trigger an awakening response. Citrus scents can also stimulate arousal.
What foods or drinks help with waking up?
Caffeinated coffee is a classic morning drink because it blocks sleep-inducing chemicals. Spicy foods, ginseng tea, and tart citrus fruits also kickstart wakefulness.
What causes a person to be such a heavy sleeper?
Deep sleepers tend to have very regular circadian rhythms. Genetics, sleep deprivation, sleep disorders, medications, alcohol, injury and other factors can also increase sleep depth and make waking more difficult.
When should a persistent heavy sleeper see a doctor?
If loud sounds, shaking, light stimulation and other tactics almost never awaken someone, an underlying health issue could be to blame. Seek medical advice to identify and address potential causes.
