Anyone who has had a few sleepless nights, whether because of work commitments or their inability to sleep, will attest that it affects their well-being in several ways. How important is sleep, and most importantly, what are its benefits and hidden perks?

The Power of Sleep: Unleashing Its Benefits

As a species, like all creatures on our planet, we rely on the 24-hour cycle dictated by the Earth’s rotation around the sun. We are not a nocturnal species, and some theories say that sleeping during the night helps us rest and avoid predators while conserving our energy for daytime activities. Therefore, our evolution helped our ancestors adapt to working during the day when they could see and resting at night when it was too dark and dangerous to work.

Our circadian rhythms are the biological patterns we adapted to survive the 24-hour cycle. These elevate our desire to sleep at night and make us more alert during the day, especially in the morning. However, the Sleep Foundation tells us that our sleep-wake cycle relies on environmental clues. In the evening, the release of melatonin, a sleep hormone, starts as darkness sets in. Come morning, melatonin levels drop dramatically, becoming almost non-existent. Interestingly, our body temperature changes with the increasing and decreasing melatonin levels. It drops in the evening and rises during the day, making the difference in how alert or ready we are for sleep.

Sleep Stages

Sleep Cycle Stages

Our evolution has made it necessary to get nightly sleep, but how important is sleep? It’s impossible to write an article on the importance of sleep without mentioning the role of sleep stages. Sleep has four stages, some lasting for a few minutes while others longer, forming a beneficial process.

The first three stages experienced during sleep are known as non-rapid eye movement (non-REM), followed by the rapid eye movement (REM) stage. It usually takes about 1.5 to 2 hours to experience all four stages.

The four sleep stages work as follows:

  • Stage N1 is the lightest stage of sleep, lasting a few minutes.
  • Stage N2 is the longest stage, with most healthy adults usually spending about half of the night in it. During this stage, the brain activity slows, but it still has bursts of activity that help retain memory and learning.
  • Stage N3 is “slow wave sleep” or “deep sleep,” which lasts between ten and twenty percent of our time sleeping. We experience lower blood pressure and a slower heart and breathing rate during this stage. The body also secretes growth hormones.
  • REM sleep occurs mostly when we are about to awake and lasts for about twenty to twenty-five percent of the sleep cycle. Our eyes move rapidly and erratically during this stage, and we have our most vivid dreams. Our skeletal muscles become temporarily numbed to prevent us from acting out our dreams. It’s the stage where memory consolidation occurs.

If an individual has stress or sleep apnea, missing out on a stage of their sleep cycle, they may experience severe consequences to their overall well-being, both physical and mental.

How Much Sleep Do We Need?

When considering the importance of sleep, it’s crucial to understand how much is enough. Experts generally agree that we need at least seven hours of nightly sleep. However, many factors determine how much sleep each person optimally needs. Our sleep needs decrease as we age.

For example, infants need up to 16 hours throughout the day and never less than 12 hours. Toddlers need between 11 and 14 hours, while preschoolers need 10 to 13 hours. Schoolgoers between six and twelve years need between nine and twelve hours; teens up to age 18 need 8-10 hours, and adults up to seven hours, sometimes.

Lack of Sleep and its Effects

The consequences of not getting enough sleep vary. One sleepless night will make clear thinking and focusing harder, and you’ll feel sluggish and irritable the next day. You may also suffer poor judgment. Sleep deprivation significantly elevates your risk of making mistakes while driving or working. If you chronically get insufficient sleep, its effects become more severe and include:

  • A suppressed immune system that makes you more susceptible to infections and illness
  • Increased risk of developing chronic ailments like heart problems, type 2 diabetes, and high blood pressure
  • Slows the metabolism, elevating your risk for obesity
  • Work and relationships may suffer
  • Increased risk of depression and anxiety
