How to Get Enough Deep Sleep: Tips and Benefits

Improve your physical and mental health by learning how to get enough deep sleep through better sleep hygiene and relaxation techniques.

What Is Deep Sleep?

Deep sleep, also known as slow-wave sleep or stage 3 NREM sleep, is a period of high-quality rest where the body undergoes significant restoration. During this stage, brain waves slow down, heart rates and breathing decrease, and muscles become very relaxed. This stage typically occurs in the first half of the night.

While sleep is composed of various stages, including REM sleep, deep sleep is distinct. In deep sleep, the body is difficult to wake; doing so may cause “sleep inertia,” a feeling of fogginess that can last up to an hour.

The Benefits of Deep Sleep

Achieving this restorative stage is essential for several bodily functions:

  • Physical Repair: It supports the regrowth and repair of muscle and bone.
  • Immune Support: It strengthens the immune system by aiding necessary hormonal shifts to fight disease.
  • Brain Health: It helps clear waste products from cerebrospinal fluid, which may be important in preventing dementia.
  • Cognitive Function: It is believed to play a role in memory formation and learning.
  • Hormone Regulation: It helps regulate prolactin and growth hormone, which affects metabolism.

How to Get More Deep Sleep

The most effective way to increase this sleep stage is to ensure you get enough total hours of rest and maintain a healthy routine.

Optimize Your Environment and Habits

  • Stick to a Schedule: Go to bed and wake up at the same time daily, including weekends, to support your circadian rhythm.
  • Create a Sleep Sanctuary: Keep your bedroom cool, dark, and quiet. Use blackout curtains, earplugs, or sound machines if your environment is noisy or bright.
  • Watch Your Intake: Limit or avoid alcohol and caffeine in the evening, as both can lower sleep quality. (Note: Those who drink large amounts of alcohol should consult a doctor before stopping abruptly due to withdrawal risks).

Manage Stress and Tension

Stress and anxiety can reduce the amount of deep sleep you receive. To relax:

  • Try meditation, yoga, deep breathing, or relaxation exercises.
  • Engage in calming activities like reading, taking a bath, or listening to quiet music.
  • Avoid thinking about or discussing stressful topics right before bed.

Explore Relaxation Techniques

Non-sleep deep rest (NSDR) is an umbrella term for practices like hypnosis, meditation, and yoga nidra. These techniques use visualization and breathing to activate the parasympathetic nervous system (the “rest-and-digest” response) and decrease the stress response. You can practice NSDR by lying down in a quiet area and listening to guided audio recordings.

Deep Sleep in Older Adults

Sleep quality often declines with age. Adults over 60 may experience a 70% loss of deep sleep compared to those aged 25 and younger. This may be due to lifestyle changes, such as less exercise, or shifts in the internal body clock.

Some research suggests that “pink noise”—sounds like falling rain or rustling leaves—may help increase slow-wave brain activity in older adults. However, evidence differs on its effectiveness; while some participants in studies saw improvements, others experienced no change.

FAQ

How much deep sleep do I need?

There is no single official guideline, but most adults typically spend 10% to 20% of their total sleep time in this stage. For someone sleeping seven to nine hours, this is roughly 40 to 110 minutes.

What happens if I don’t get enough deep sleep?

A lack of restorative sleep can interfere with memory, learning, and the removal of brain waste. It may also disrupt hormone release. General sleep loss is linked to mood changes, difficulty focusing, and a higher long-term risk of stroke, high blood pressure, obesity, and type 2 diabetes.

How does NSDR work?

NSDR uses attention exercises and visualization to slow the brain’s electrical waves and increase dopamine. This induces a state of deep relaxation that can lower blood pressure and heart rate.

Is NSDR better than a nap?

Researchers have not directly compared the two, though some experts suggest that light naps may function similarly to NSDR.

When to See a Doctor

Consult a healthcare provider if you experience the following:

  • Sleep problems that do not improve after trying healthy sleep tips.
  • Sleep issues that significantly interfere with your daily activities or work.
  • Suspicions that a medication or underlying medical condition is causing sleep disruptions.
  • Severe stress or anxiety that does not improve with self-care.
