Throughout your entire sleep, four individual stages progress throughout your nightly sleep. The sleep architecture is divided into four stages: one stage is rapid eye movement (REM) sleep, and three other stages are non-REM (NREM) sleep:

  • Stage 1 is NREM which lasts for 1-5 minutes
  • Stage 2 is NREM which lasts about 10-60 minutes
  • The next stage, i.e., Stage 3, is also NREM but deep sleep, which lasts about 20-40minutes
  • Lastly, stage 4 is REM which lasts for 10-60 minutes.

Stage 3 sleep is Deep sleep, also known as slow wave sleep and delta sleep. In this stage, toxins are flushed out from the cerebrospinal fluid4, the immune system recovers, and human growth hormones are released.

The brain, at this stage, produces slow brain waves, which are also called delta waves, hence the name. Slow brain waves are relatively high amplitude and low-frequency waves responsible for letting your body relax.

It’s harder to wake someone up from this phase. Also, the muscle tone, breathing rate, and pulse decline from the normal rate as the body loosens up and relaxes. It is backed by scientists and researchers worldwide that this stage is critical to therapeutic sleep, allowing the body for restorative recovery and elevated growth.

Not only bodily recovery, but this stage is also responsible for enhancing out-of-box thinking capabilities, perceptive reasoning, vision, and memory.

Wondering how much time an average adult’s body spends in deep sleep? The N3 stage lasts for 20-40 minutes. Also, deep sleep occurs during the first half of the night.

Many factors influence sleep stages, i.e., age, sleep pattern, alcohol, and sleep disorders like RLS, insomnia, sleep apnea, and much more. Adults spend less time in deep sleep than children. As one gets older, the duration of deep sleep throughout the night also decreases.

4. Deep Sleep And The Immune System

One of the most important benefits of deep sleep is its impact on the immune system. Let us see the relationship between deep sleep and the immune system 6and discuss how deep sleep is necessary to boost your immune system.

The human growth hormone (HGH) is a hormone that is produced during deep sleep and plays a crucial role in the immune system. HGH is responsible for promoting cell growth, repairing damaged tissues, and boosting the immune system7. During deep sleep, the body produces more HGH, which helps to repair and restore the body.

Sleep medicine experts have long known that sleep is essential for maintaining a healthy immune system. Studies have shown that people who get enough deep sleep have a stronger immune system and are less likely to get sick. In contrast, sleep deprivation or poor sleep quality can lead to a weakened immune system, making you more susceptible to infection and illness.

The sleep cycle is divided into two main stages: non-rapid eye movement (NREM) sleep and rapid eye movement (REM) sleep. NREM sleep is further divided into three stages: stage 1, stage 2, and stage 3. Stage 3, also known as deep sleep, is the most restorative stage of the sleep cycle. During deep sleep, the body produces more HGH and repairs and restores the body.

REM sleep is the stage of sleep during which most dreaming occurs. Although REM sleep is important for the brain, it is not as restorative for the body as deep sleep. People who have trouble falling asleep or staying asleep often have trouble reaching the deep sleep stage, which can lead to sleep deprivation and a weakened immune system.

There are several factors that can affect deep sleep and the immune system. One of the most important is high blood pressure. High blood pressure can lead to sleep apnea, a condition in which a person stops breathing during sleep. Sleep apnea can disrupt deep sleep and lead to a weakened immune system.

Another factor that can affect deep sleep and the immune system is a poor diet. A diet that is high in sugar and processed foods can lead to weight gain and increase the risk of sleep apnea and other sleep disorders. A healthy diet that is rich in fruits, vegetables, and whole grains can help improve sleep quality and boost the immune system.

Body temperature also plays a role in deep sleep and the immune system. The body’s temperature drops during deep sleep, which helps to promote sleep. However, if the bedroom is too warm or too cold, it can make it difficult to fall asleep and disrupt deep sleep.

In addition to these factors, sleep time also plays a crucial role in deep sleep and the immune system. Adults should aim for 7-9 hours of sleep per night to ensure that they are getting enough deep sleep to boost the immune system.
