Tu dors 8h par nuit mais tu es toujours fatigué :

what it claims

If you sleep 8 hours a night but remain tired, the solution is to track and analyze your sleep holistically by connecting your various devices (watches, rings, phones) on a single platform.

The value of using connected technologies to assess rest is scientifically grounded: a 2026 meta-analysis evaluating sleep trackers confirms that they provide reasonable overall estimates of sleep duration. Furthermore, a randomized controlled trial (RCT) published in the Journal of Clinical Sleep Medicine demonstrated that tracking via wearable sensors significantly improves users' subjective perception of sleep quality. However, presenting the centralization and analysis of this data as the direct solution to persistent fatigue is an exaggeration. The 2026 meta-analysis indeed notes that these devices tend to overestimate actual sleep time and still lack the fine precision to distinguish deep recovery cycles. Finally, fatigue despite 8 hours of sleep often stems from broad lifestyle factors (such as stress levels or light exposure) that simple technological observation alone cannot correct.

Excessive use of active ingredients (acids, retinoids) damages the skin's protective barrier, causing blemishes and redness often mistaken for hormonal acne. To restore clear skin, it is necessary to suspend these actives and apply soothing and repairing ingredients such as niacinamide, centella asiatica, panthenol, and ceramides.

Protecting your ears from excessive noise helps preserve your non-regenerative auditory cells, which assists in maintaining mental sharpness and preserving memory over the long term.

Wear hearing protection in very noisy environments, such as concerts, to avoid irreversible damage to the inner ear and thereby reduce the long-term risk of cognitive decline and dementia.

Others on this

Needlessly delaying bedtime ("bedtime procrastination") is framed here as coming from not having processed the day's emotions — working through them before bed supposedly helps you fall asleep.

Sleep isn't dead time for your muscles — muscle protein synthesis keeps repairing and rebuilding tissue damaged during the day while you're out.

If you run hot at night, cooling the bed down (a fan, a cooling pad, or a cooled mattress) genuinely helps you sleep better.

Other advice in the Register that leans on the same research.

If you sleep 8 hours a day but remain tired, this may be explained by specific physical factors to explore: sleep apnea, an iron deficiency (particularly in women and vegetarians), a lack of vitamin D (ideally between 30 and 50 ng/mL) or B12, or even hormonal fluctuations.

Many sleep disorders (insomnia) are not simply inevitable, but rather warning signals of underlying biological imbalances, particularly a drop in progesterone linked to perimenopause, insufficient iron stores, or variations in thyroid activity.

holds upLucile Woodward

Chronic fatigue that persists despite sufficient sleep duration is often caused by constant hyperactivity of the nervous system, which prevents the body from achieving deep recovery, rather than by nutritional deficiencies.
