Sleep less to live more? In a society that glorifies productivity, some find that 24-hour days are not enough. Their solution? Cut down on sleep.
Thus, many claim that "6 hours of sleep is enough," or even less. This discourse is appealing but goes against what science tells us.
Here's why this myth should be taken with a grain of salt, and what you really need to understand about sleep requirements.
Where does this idea come from?
The idea that one could "train" their body to get by with 6 hours of sleep is often based on testimonials from famous personalities (entrepreneurs, artists, leaders) who claim to have functioned this way for years.
Added to this is a culture of performance that associates long nights with laziness, and shortened sleep with efficiency. However, these discourses overlook an essential point: they are the exception, not the biological norm.
The body's true needs
Official recommendations, particularly those from the National Sleep Foundation, indicate that an adult needs 7 to 9 hours of sleep per night to function optimally.
Chronically sleeping less than 6 hours increases the risk of:
- attention and memory problems,
- irritability and mood disorders,
- decreased immune defenses,
- hormonal imbalances (including leptin and ghrelin, which regulate appetite),
- weight gain and insulin resistance,
- chronic fatigue, etc.
In short: even if you think you can "cope" with 6 hours of sleep, your body will absorb the impact silently until it gives up.
Why sleep is essential for performance (even athletic)
Sleep is far from being a simple "break": it is an active phase during which the body regenerates its tissues, consolidates memory, regulates the hormonal system, and recharges its batteries. For athletes, it is a key moment for:
- muscle recovery,
- protein synthesis,
- inflammation regulation,
- oxidative stress management.
Sleeping less means compromising results and increasing the risk of injury. Whether you are bulking, losing weight, or simply seeking vitality, sleep remains your best ally.
How to promote better quality sleep?
Before trying to sleep more, it is essential to sleep better. The quality of sleep depends on many factors that can be optimized daily. Here are some good practices to adopt.
Establish a regular routine
It all starts with a regular routine: going to bed and waking up at the same time each day, including weekends, helps regulate the internal clock. Exposure to natural light in the morning and dim light in the evening also reinforces this regulation.
Reduce screen time
It is advisable to reduce screen time at least one hour before bedtime, as blue light blocks the production of melatonin, the sleep hormone. Prefer a calm activity: reading, meditation, gentle stretching.
Sleep in a cool environment
The bedroom temperature is important: between 17 and 19°C (62-66°F) is ideal. Also ensure good darkness and silence, or use a mask and earplugs if necessary.
Eat light
Finally, regarding diet, avoid heavy meals, stimulants like caffeine or alcohol in the evening, and prioritize sources of tryptophan (eggs, bananas, legumes, oats) which promote melatonin production.
These habits, simple but powerful, can transform the quality of your nights and your days.
Can dietary supplements help you sleep better?
As seen previously, good sleep primarily involves a healthy lifestyle: limiting screens in the evening, maintaining a regular rhythm, avoiding stimulants... But some people may need a little boost to regain restorative sleep.
Dietary supplements can then be valuable aids, especially those based on:
- ZMB: zinc, magnesium, and vitamin B6 for optimal nervous and muscular recovery
- Lactium: promotes faster falling asleep thanks to its relaxing properties.
- Crystallized Glycine: contributes to quality sleep by supporting nerve signal transmission.
You can also opt for adaptogenic plants like ashwagandha, and also valerian, passionflower, or lemon balm, known for their calming effect.
They do not replace good habits but can help to get the body back into a healthier cycle.
Key takeaways
No, sleeping 6 hours a night is not enough for most people. This myth is based more on anecdotes than on facts.
Sleep is not a waste of time: it is a pillar of health, just like diet or physical activity. Respecting it means investing in your physical and mental performance, and in your longevity.
