Understanding Sleep And Its Impact On Your Life


According to Wikipedia, Sleep is a naturally recurring state of mind and body. During this state, there is

  • Altered consciousness
  • Inhibited sensory activity
  • Reduced muscle activity
  • Decreased ability to respond to stimuli

What Happens During Sleep


Sleep accounts for ¼ to 1/3 of the human lifespan. It would make sense to at least understand what happens while we sleep. Sleep is divided into non-REM sleep and REM sleep. REM stands for Rapid Eye Movement.

Non-REM Sleep: This consists of 4 stages

1st Stage: This happens between being awake and falling asleep

2nd Stage: This stage involves light sleep. The heart rate and breathing are regulated and there is a drop in body temperature

3rd and 4th Stage is deep sleep.

New data suggests that non-REM is the more important sleep for memory and learning.

REM sleep: During this stage, your eyes are engaged in rapid movement from side to side under closed eyelids.

  • Brain activity is elevated, heart rate increases
  • Dreams are most common during this phase
  • Memory is processed and stored during this phase
  • Tends to occur late at night into the early morning

One cycle of REM and non-REM lasts about 90 mins.

Circadian Clock Rhythm

This is an internal clock that alerts the body when it’s about to sleep. Circadian clocks are found in the brain and other organs. They are triggered by daylight(alertness) and darkness (drowsiness). They can also be triggered by stimulants such as caffeine, alcohol, and energy drinks.

Why Are You Not Falling Asleep?

Insufficient sleep can lead to attention and behavioral problems. Sleep helps to process your thoughts from the day as well as store memories. Lack of good sleep can impair memory, and increase irritability, and anxiety.

Bad sleeping habits include
  • Looking at phone screens, and computer screens late at night
  • Drinking caffeinated or alcoholic beverages at night.
  •  Not following a regular sleep schedule
  •  Sleeping in an environment that is too noisy
  •  Drastic changes to the body’s natural circadian clock (people that work night shifts)
  • Having a sleep disorder e.g., Sleep apnea, insomnia, restless leg syndrome
  • Medical conditions such as heart, lung, or kidney issues can impair sleep over a long period of time
  • Chronic pain
Sleep Deficiency

Sleep Deficiency is a condition in which your body has gone continuously without sleep. It is a state in which you cannot make up lost hours. Sleep deficiency can increase the risk of

  • Obesity
  • Diabetes
  • Depression
  • Dementia
