Sleep Stages
Sleep is divided into three main stages: deep, REM, and light. Each stage has its own characteristics and plays a vital role in the overall quality of sleep.
Deep Sleep
Deep sleep, also known as slow-wave sleep, is the most restorative stage of sleep. During this stage, the body repairs and regenerates tissues, strengthens the immune system, and releases hormones that regulate growth and appetite.
On average, adults spend around 13-23% of their sleep in deep sleep, with the percentage decreasing as we age. The table below shows the average percentage of deep sleep by age group:
| Age Group | Average Deep Sleep Percentage |
|---|---|
| 18-24 | 20% |
| 25-34 | 18% |
| 35-44 | 16% |
| 45-54 | 14% |
| 55-64 | 12% |
| 65+ | 8% |
REM Sleep
REM (rapid eye movement) sleep is the stage where most dreaming occurs. It is also crucial for memory consolidation and learning. During this stage, the brain is highly active, and the body is paralyzed to prevent acting out dreams.
On average, adults spend around 20-25% of their sleep in REM sleep, with the percentage staying relatively constant throughout adulthood. The table below shows the average percentage of REM sleep by age group:
| Age Group | Average REM Sleep Percentage |
|---|---|
| 18-24 | 25% |
| 25-34 | 23% |
| 35-44 | 22% |
| 45-54 | 21% |
| 55-64 | 20% |
| 65+ | 19% |
Light Sleep
Light sleep is the stage between deep sleep and REM sleep. It is characterized by slower brain waves and muscle activity. During this stage, the body prepares to enter deep sleep or REM sleep.
On average, adults spend around 50-60% of their sleep in light sleep, with the percentage increasing as we age. The table below shows the average percentage of light sleep by age group:
| Age Group | Average Light Sleep Percentage |
|---|---|
| 18-24 | 55% |
| 25-34 | 57% |
| 35-44 | 60% |
| 45-54 | 62% |
| 55-64 | 64% |
| 65+ | 67% |
Knowing the percentage of each sleep stage can help individuals understand their sleep quality and make necessary adjustments to improve it.
Factors Affecting Sleep Score
When it comes to tracking our sleep, Fitbit has become one of the most popular wearable devices. However, the accuracy of the sleep score it provides can be influenced by several factors. Here are some of the most important factors that can affect your Fitbit sleep score:
