Sleep: The Different Stages of Sleep

Sleep: The Different Stages of Sleep

By Crystal Tsui

Have you ever wondered why at certain times of the night you tend to be more alert and other times you dream, unaware of your surroundings? That’s because there are different stages of sleep, more specifically five stages.

  • Stage 1
  • Stage 2
  • Stage 3
  • Stage 4
  • REM (rapid eye movement)

How do we determine what stage is what? Sleep researchers use an electroencephalogram (EEG), is a method used to monitor and record electric cortical brain activity, and other instruments to help determine the stages.

In Stage 1, researchers found that this cycle is the lightest sleep. On the EEG, the frequency is slower than when we are awake. Physically, our muscles relax and our breathing occurs at a regular rate.

In Stage 2, we are less likely to be awakened. Our heart rate and temperature decreases as our body is preparing to go into a deep sleep.

In Stage 3 and 4, we begin our deep sleep. It’s harder to be awakened because at this point our body becomes less responsive to outside stimuli. In these stages, our body starts to restore itself, stimulate growth and development, boosts immune function, and builds energy for the next day.

In REM, dreaming occurs, our eyes quickly jerk in different directions, heart rate and blood pressure increase, and our breathing become fast and shallow. This stage generally lasts up to an hour and begins about 90 mins after you initially fall asleep. This is an important stage because our brain starts to consolidate all the information we have learned during the day into our long-term memory.

In children, one cycle can last up to 50-60 mins and increases to 1-1.5 hours in adults. It is advised:

  • Babies (0 months – 11 months) get 14-18 hours
  • Toddlers (1-5 yrs) get 12-13 hours
  • Children (6-10 yrs) get 8.5- 11 hours
  • Pre-teens and teenagers (11-17) get 8-10 hours
  • Adults (18-65+) get 7-9 hours of sleep

Sleep Disorder: Narcolepsy

Sleep Disorder: Narcolepsy

By Crystal Tsui

Narcolepsy is a chronic sleep disorder that affects daytime activities. It is characterized by overwhelming drowsiness and sudden attacks of sleep. Narcolepsy affects both men and women equally in roughly 1 in 2,000 people and can be passed down genetically, but the risk of a parent passing this disorder to a child is very low. Symptoms usually start to develop between the ages of 10- 30 years old and worsen for the first few years. The symptoms of narcolepsy will remain constant throughout life.

Some symptoms of narcolepsy include:

  • Excessive sleepiness
  • Sleep paralysis
  • Hallucinations
  • Episodes of cataplexy (partial or total loss of muscle control that is often triggered by strong emotions such as laughter and joy)

Other symptoms include:

  • Transition to REM sleep is quick, usually 15 minutes
  • Insomnia
  • Restless leg syndrome
  • Sleep apnea
  • Automatic behavior (falling asleep while doing an automatic task, like driving, and continue performing task after falling asleep. When waking up and not remembering what they did)

Narcolepsy is a sleep disorder that seriously disrupts everyday life. Most common being:

  • Stigma of the condition- others might view individuals with this disorder as lazy or lethargic
  • Physical harm- increased risk of being in a car accident if a sleep attack occurs when driving
  • Low metabolism- individuals may be more likely to be overweight

Unfortunately, the exact cause is still unknown and there is no cure for narcolepsy. However, medications (stimulants), lifestyle changes, and support from others can help manage symptoms.
