"The older you get, the lighter your sleep becomes"? This is not natural aging, but a sleep structure problem that can be improved

1. Why do we sleep more lightly as we get older?

According to the National Sleep Foundation, as people age, especially from the age of 50 , their " deep sleep " ( N3 stage) decreases significantly, and is replaced by light sleep and frequent awakenings at night. This is mainly because:

•       The brain's sleep regulation mechanism gradually degenerates , making it more sensitive to external stimuli

•       The decrease in neurotransmitters such as melatonin and GABA makes it difficult to fall asleep and maintain sleep

•       Increased activity of the arousal system ( orexin ) causes wakefulness signals to override the " desire to sleep "

📌 Many middle-aged and elderly people have formed a misunderstanding because of this: " It is normal to have poor sleep as you get older ." In fact, this is just a change in the mechanism and does not mean that there is no solution.

 

2. Sleep structure is the key to determining whether you sleep well or not

" Sleep architecture " refers to the distribution of different stages of sleep during a night:

•       N1 : Light sleep

•       N2 : Stable sleep

•       N3 : Deep sleep stage, a critical period for body repair, immune regulation, and brain metabolism clearance

•       REM : Rapid Eye Movement, active dreaming, consolidation of memories

📌 In a night of sleep, the N3 stage should account for 15% to 25% of the total time . In the middle-aged and elderly population, this proportion often drops to less than 10% , which directly leads to:

•       Feeling tired and out of spirits after waking up

•       Difficulty concentrating and memory loss during the day

•       Decreased immunity and metabolic recovery ability

 

3. Darilexan: A new generation of sleeping pills designed to improve the problem of " shallow sleep "

Darilexant is an orexin receptor antagonist ( ORAs ) that blocks the OX1R/OX2R pathway of the wakefulness system, allowing the body to enter a natural sleep state rather than " forced sedation " like traditional drugs.

Features	Dale Raisin	Traditional sleeping pills (such as diazepam)
Mechanism of action	Regulate the wakefulness system, help you sleep without disrupting your rhythm	Acting on the GABA system, forcibly inhibiting nerves
Deep sleep effects	Improve N3 sleep ratio	Suppresses deep sleep, promotes shallow sleep and memory impairment
Addictive	No dependence, can be used for a long time	Easy to tolerate, high risk of dependence
Next day impact	No "hangover feeling", sober and natural	Dizziness, slow reaction, and strong drowsiness the next day

📌 Clinical studies have shown that dalirenoxam can not only significantly prolong the duration of deep sleep , but also does not interfere with the REM phase , thereby improving the overall quality of sleep structure ( Muehlan et al., 2022 ).

 

4. Which middle-aged and elderly people are particularly helpful?

•       People who have no difficulty falling asleep but easily wake up in the middle of the night and cannot fall back asleep after waking up

•       People who feel tired and unrefreshed after sleeping for 7-8 hours

•       People who feel drowsy and unresponsive during the day after taking traditional sleeping pills

•       People who want to improve sleep safely in the long term but are concerned about side effects and dependence

Dali Leisheng is suitable as a rhythm-regulating sleep aid to help middle-aged and elderly people gradually restore their natural sleep rhythm.

 

5. Conclusion: Poor sleep is not due to “ aging ” , but “ can be improved by science ”

Don’t let the idea that you shouldn’t be able to sleep when you’re older hold you back from living a healthy life. Sleep is not a luxury that you can’t have, but a core mechanism for restoring your body’s functions, protecting your brain’s cognition, and resisting disease.

📌 As a safe, non-addictive sleeping aid that promotes deep sleep, Dali Lexan is an effective means to help middle-aged and elderly people rebuild a high-quality sleep structure .
