Sleep: how does work?

 

Sleep is a fascinating universe that science has not stopped exploring. What we know today is that when we sleep, we go through several sleep cycles of 60 to 120 minutes each.

For quality sleep, ideally you should chain 3 to 6 sleep cycles – it all depends on whether you are in the “little sleeper” or “heavy sleeper” leaue.

During a cycle, you will go through different stages of sleep:

  1. Falling asleep
  2. Slow light sleep
  3. Deep slow sleep
  4. REM sleep, or Rapid Eye Movement sleep, because this phase is marked by rapid eye movements.

Deep slow sleep is characterized by a slowing down of the whole organism: it is the sleep phase during which we recover the most.

REM sleep owes its name to the contradictory signals that can be observed during this phase: brain activity is very intense, while the body is still. Researchers believe that our dreams arise during REM sleep.

Health, quality of life, sleep: what’s the point of sleeping?

 

Sleep plays a fundamental role for our organism, and for our physical and mental health.

If the amount of studies on sleep keep on growing, it is because it has been demonstrated that the quality of our sleep and our health are linked.

We now know that poor sleep increases the risk of cardiovascular disease, obesity, diabetes, and cancer. It also plays a role on irritability, depressive symptoms, hypertension …

And, as you will have noticed, poor quality of sleep impedes our concentration, our learning, our memory skills … Sleep is also crucial for brain maturation and growth, hence the importance of sleep in children.

In short, taking care of your sleep is taking care of your health.

Sleep disturbances: what disrupts our natural rhythm?

Our environment, our lifestyle and the rhythm of our days have an influence on the quality of our sleep.

We consider that on average, since the last 50 years, French people have lost between 1h and 1h30 of sleep time due to the evolution of environmental factors: noise, brightness of screens and them time spent indoors each day disrupt our ability to sleep well.

The most common sleep disorders are:

  • insomnia, whether punctual or chronic;
  • difficulty falling asleep, waking up at night or feeling sleepy;
  • circadian rhythm disorders, the disruption of our biological clock;
  • sleep apnea;
  • parasomnias: these are disorders that occur during sleep such as sleepwalking or night terrors.

Several factors can contribute to trigger or worsen these phenomena. Some are specific to each individual, but others are external: lifestyle, the use of screens, the degree of exposure to natural light or the taking of certain drugs disturb the natural functioning of sleep.
