Let's talk about something we all love but rarely really think about: sleeping. We spend about a third of our lives dreaming and snoring, but why? What exactly happens when we sleep and why is it so important for our well-being?
What happens during sleep?
When we close our eyes for the night, our body begins a fascinating journey through different sleep phases. The two main characters in this story are REM (Rapid Eye Movement) sleep and non-REM sleep, each with their own unique phases. These sleep cycles are like a kind of nightly rest stop, they help our body and mind to recharge and be ready for a new day.
This form of sleep consists of three phases:
- Light sleep: This is the transition phase between wakefulness and sleep. It is a period of light sleep during which we can be easily awakened.
- Deep sleep: In this phase we are not so easy to wake up. When we are woken up, we often feel disoriented for a moment.
- Deepest sleep: This is where the real recovery work happens. It's time for tissue growth, repair and a boost to our immune system.
This is the stage where most dreams take place. Our brains are almost as active during this phase as when we are awake. It is also the phase in which our brain processes the events and information of the day and stores them in our memory.
What is the importance of sleep?
Sleeping is like the 'MOT' of our body. It contributes to healthy growth and development, helps restore various systems in our body and plays an important role in maintaining our physical health.
Sleeping is also a kind of mental detox. It allows our brain to rest and recover, allowing us to function better the next day. In addition, a good night's sleep helps us learn and remember information. (concentration and memory)
It also has a positive effect on our emotional well-being. A good night's sleep can help us deal with stress better and can even improve our mood.
What can (negatively) influence your night's sleep?
There are several factors that can hinder a good night's sleep, and they are as diverse as we humans are. Here are a few you might recognize:
- Snoring: Not only a nighttime inconvenience for those who have to tolerate the noise, but also for the snorer himself. Snoring can be a sign of sleep apnea, a condition that can interrupt your sleep.
- Jet lag: For those who frequently travel across different time zones, jet lag can really mess up the body's internal clock, leading to sleep problems.
- Irregular working hours: People who work shifts or have irregular hours may struggle with maintaining a consistent sleep-wake schedule, which is essential for a good night's sleep.
- Heat: A room that is too warm can make it difficult to fall and stay asleep. The ideal bedroom temperature is around 16-18 degrees Celsius.
- Stress and anxiety: Emotional stress and anxiety can overload your mind, making it difficult to relax and fall asleep.
- Blue light: The light from electronic devices such as phones, tablets and computers can suppress the production of melatonin, the hormone that makes you sleepy.
- Food and drink: Caffeine and alcohol can negatively affect the quality of your sleep, while heavy or spicy food close to bedtime can also cause sleep problems.
These factors can all contribute to sleep problems. Fortunately, there are strategies and techniques that can help with sleep problems and improve your night's sleep.

Striving for a better night's sleep is no easy task, but there are several effective strategies that can help with sleep. Here are a few key steps:
