What's a good night's sleep?

Sleep is essential, but knowing what "sleeping well" really means is sometimes a nebulous concept. Many people think that long sleep is the key, but the quality of sleep counts as much as the quantity. Sleeping well means offering your body the best conditions to regenerate and wake up with genuine energy, without depending on stimulants. So, let's take a look at what defines quality sleep.

1. The ideal length of sleep

It's recommended that adults sleep between 7 and 9 hours a night. However, optimal sleep duration may vary slightly according to individual needs. Getting enough sleep helps the body repair itself, consolidate memory and regulate biological functions.

2. Sleep cycles

Good sleep involves complete sleep cycles, including light sleep, deep sleep and REM sleep. These cycles repeat themselves approximately every 90 minutes. Deep sleep is crucial for physical recovery, while REM sleep supports cognitive functions.

3. The importance of the sleep environment

Sleeping well also means creating the right environment: a dark, quiet, cool bedroom helps optimize sleep. Blue light from screens before bedtime disrupts the production of melatonin, the sleep hormone. Turning off screens at least an hour before bedtime can help you fall asleep more quickly.

4. Sleep routines

The human body likes regularity. Going to bed and getting up at the same time every day helps stabilize circadian rhythm, our internal clock. A soothing pre-bedtime routine, such as reading or meditation, can signal to the body that it's time to relax and prepare for sleep.

Conclusion

Sleeping well doesn't just mean accumulating hours of sleep, but providing your body with a quality of sleep that enables complete recovery. Good sleep hygiene, a suitable environment and regular routines are the keys to waking up fit and ready to face the day. At the end of the day, a good night's sleep is an investment in your health and energy.
