Struggling to Sleep? It May Not Be Because You’re Not Tired Enough - Your Body May Still Be in “Stress Mode”
Many people who struggle with sleep share the same experience:
Their body feels exhausted, but their mind simply won’t switch off.
After spending the day working, worrying, meeting deadlines and constantly thinking, the mind can remain tense and alert. Even after getting into bed, thoughts continue racing.
Some people take a long time to fall asleep. Others sleep lightly, wake during the night and struggle to fall back asleep. Some may even sleep through the night but still wake up feeling tired and unrefreshed.
In these situations, the question may not simply be “How can I fall asleep faster?”
A more important question may be:
Why hasn’t my body truly relaxed by the time I go to bed?
This is where Pine Restora (Sho-ko-sen) may be particularly relevant. Its focus is not simply on sleep itself, but on helping the body move away from a state of persistent tension and stress.
1. Supporting the Body During Stress-Related Sympathetic Nervous System Activation
When we are stressed, anxious, rushing or concentrating intensely, the sympathetic nervous system becomes more active.
A certain level of sympathetic nervous system activity is completely normal. However, when this heightened state continues into the evening, it can feel as though:
You may be lying in bed, but your body is still “at work.”
A 2022 study published by the Japanese Pharmacological Society examined healthy young participants who completed continuous calculation tasks designed to induce mental stress. Researchers monitored changes in autonomic nervous system activity using heart rate variability.
The placebo group showed an increase in indicators associated with sympathetic nervous system activity following the stress task, while participants who consumed pine nodule extract did not demonstrate the same degree of increase. The researchers suggested that pine nodule extract may have an anti-stress effect.
This highlights an important aspect of Pine Restora in relation to sleep:
Rather than simply making you feel sleepy, the research focuses on stress responses and sympathetic nervous system activity, potentially helping the body slow down more naturally.
For people who feel “the more exhausted I am, the harder it is to sleep” or “the more I try to sleep, the more awake I become,” this distinction may be particularly relevant.
2. Supporting Autonomic Nervous System Balance
Our bodies broadly move between two different states:
- a state associated with activity, stress, alertness and responding to demands; and
- a state associated with relaxation, rest and recovery.
The autonomic nervous system plays an important role in regulating the transition between these states.
In 2023, further research specifically investigated Sho-ko-sen (Pine Restora) in a paper titled “Effects of pine nodule extract, Sho-ko-sen, on mental stress-induced changes in the autonomic nervous balance in young students.”
Published in Current Topics in Pharmacology, the study investigated the effects of Sho-ko-sen on changes in autonomic nervous system balance caused by mental stress. The University of the Ryukyus research repository lists the publication as a peer-reviewed research paper.
This provides a useful way of understanding one of Pine Restora’s key areas of research:
Supporting the body during periods of stress and helping maintain a more stable autonomic nervous system response.
This may be particularly relevant when sleep difficulties are closely associated with stress and persistent tension.
3. Researching Stress-Related Pathways — Not Simply Relying on Traditional Use
During periods of stress, the body releases catecholamines such as adrenaline and noradrenaline through stress-response pathways involving the sympathetic nervous system and adrenal glands.
These substances are not inherently harmful. They are essential when we face danger, exercise or need to remain highly focused.
The problem arises when the body remains in a heightened state for prolonged periods, making it more difficult to transition into genuine relaxation.
A 2017 study published in the Journal of Pharmacological Sciences found that pine nodule extract, as well as a studied constituent referred to as SJ-2, inhibited acetylcholine-induced catecholamine secretion and synthesis.
Importantly, this experiment was conducted using bovine adrenal medullary cells. It therefore represents mechanistic laboratory research and should not be interpreted as direct evidence of a therapeutic effect in humans. However, it provides a potential pharmacological direction for understanding how pine nodule extract may influence physiological stress responses.
Put simply, the research surrounding Pine Restora goes beyond saying that it simply “helps you relax.”
Researchers have investigated mechanisms associated with the sympathetic nervous system, catecholamines and the body’s response to stress.
4. Particularly Relevant to Stress-Related Sleep Difficulties
So, who may find the research surrounding Pine Restora particularly relevant?
Rather than simply saying “people with insomnia,” it may be more useful to think about people who:
- experience significant stress during the day and cannot switch their mind off at night;
- find themselves thinking more as soon as they lie down;
- feel physically exhausted but remain tense;
- wake easily because of small noises or disturbances;
- wake during the night and immediately begin thinking again; or
- sleep through the night but still wake feeling as though they have not properly rested.
The common theme is simple:
The body may be tired, but the nervous system has not fully relaxed.
Current research into Sho-ko-sen has focused on mental stress, sympathetic nervous system responses and autonomic nervous system balance — areas that may be particularly relevant to this type of stress-related sleep difficulty.
5. The Goal Is Not to “Force” Sleep, but to Help Create Better Conditions for Rest
This is an important distinction when discussing Pine Restora.
When people think about products associated with sleep, one of their first questions is often:
“Will it make me sleepy straight away?”
However, the currently available research on Sho-ko-sen does not primarily focus on a direct sedative or hypnotic mechanism. Instead, research has concentrated more on stress responses, autonomic nervous system activity and catecholamine-related mechanisms.
A more accurate way to understand its research, therefore, is not as something designed to “force the brain to switch off,” but as something investigated for its potential role in reducing the physiological state of persistent tension associated with stress.
When the stress accumulated throughout the day begins to ease and the sympathetic nervous system is no longer continuously highly activated, the body may find it easier to transition from “work mode” to “rest mode.”
That is why managing sleep should not always focus solely on whether you can fall asleep.
It can also be helpful to consider:
Can your body genuinely relax? Is your sleep restful? Do you wake up feeling recovered?
In summary, the research surrounding Pine Restora focuses on:
- supporting the body in response to mental stress;
- reducing excessive sympathetic nervous system activation associated with stress;
- supporting autonomic nervous system stability;
- investigating stress responses through catecholamine-related mechanisms; and
- helping create conditions in which the body can relax and rest.
Because for many people struggling with sleep, the problem may not be a lack of tiredness.
The problem may be that, even at night, the body still doesn’t know how to relax.
After spending the entire day pushing through stress and remaining tense into the evening, it is understandable that the body can begin to feel increasingly exhausted.
For people experiencing long-term work pressure, mental tension, persistent overthinking or difficulty unwinding at night, it may therefore be worth looking beyond simply trying to “fall asleep as quickly as possible.”
Instead, consider another question:
How can the body truly step out of stress mode?
As stress begins to ease and the body gradually relaxes, sleep may have a better opportunity to return to its natural rhythm.
很多睡不好的人都有一种共同感受：
身体已经很累了，脑子却停不下来。
白天工作、操心、赶进度，精神一直绷着；到了晚上，明明已经躺在床上，大脑却还在不断想事情。
有的人入睡慢，有的人睡得浅，有的人半夜醒来以后很难再睡，还有的人虽然睡了一整晚，第二天起来还是觉得累。
这时候，真正需要关注的，可能不只是“怎么让自己赶快睡着”，而是：
为什么到了晚上，身体依然没有真正放松下来？
而这正是松康泉值得关注的地方。松康泉的重点，不只是“睡”，而是先帮助身体从紧绷状态中松下来
一：帮助减轻压力状态下的交感神经过度兴奋
人在紧张、焦虑、赶时间或者高度用脑的时候，身体的交感神经会更加活跃。
适度的交感神经兴奋是正常的，但如果到了晚上依然处于这种状态，就很容易出现一种感觉：
人躺下了，身体却还像在“上班”。
2022年日本药理学会发表的一项研究，让健康年轻受试者进行连续计算任务制造精神压力，并通过心率变异性观察自主神经变化。
结果发现，安慰剂组在压力任务后出现交感神经相关指标升高，而摄入松节提取物的人群没有出现同样程度的交感神经升高。研究人员认为，松节提取物具有一定的抗压力作用。
这也是松康泉在睡眠领域特别值得强调的一点：
它不是简单让人“困”，而是从压力状态和交感神经反应这个方向，帮助身体更容易慢下来。
对于那种“越累越睡不着、越想睡越清醒”的人，这个逻辑就很好理解。
二：帮助维持自主神经平衡，让身体更容易切换到休息模式
我们的身体大致存在两种不同的状态：
一种是应对压力、工作、紧张和兴奋的状态；
另一种是放松、休息和恢复的状态。
而自主神经系统就参与着这种状态切换。
2023年，相关研究进一步以 Sho-ko-sen（松康泉）为对象，发表了《Effects of pine nodule extract, Sho-ko-sen, on mental stress-induced changes in the autonomic nervous balance in young students》，研究主题就是观察松康泉对精神压力引起的自主神经平衡变化的影响。该研究发表于 Current Topics in Pharmacology，琉球大学研究成果数据库将其列为经过同行评审的研究论文。
所以，松康泉一个非常好理解的核心卖点就是：
帮助身体在面对压力时不过度“绷紧”，帮助自主神经保持更加稳定的状态。
这对于压力型睡眠问题尤其有意义。
三：从“压力激素相关通路”研究松节，而不是只停留在传统经验
人在压力状态下，身体会通过交感神经—肾上腺系统释放包括肾上腺素、去甲肾上腺素等在内的儿茶酚胺。
这些物质本身并不是坏东西——遇到危险、运动或者需要集中注意力时，它们非常重要。
问题是，如果身体长期处于高度紧张状态，就很难真正进入放松模式。
2017年发表在 Journal of Pharmacological Sciences 的研究发现，**松节提取物以及其中研究的一种成分SJ-2，可以抑制乙酰胆碱诱导的儿茶酚胺分泌和合成。**这项研究是在牛肾上腺髓质细胞中完成的，因此属于机制层面的实验研究，不能直接等同于人体治疗效果，但它为松节为什么可能影响压力反应提供了一个药理学方向。
简单讲就是：
松康泉的研究并不是只说“吃了比较放松”，而是在研究身体面对压力时，与交感神经和儿茶酚胺有关的反应机制。
这会比单纯说“安神助眠”更有科学说服力。
四：更适合“压力型、紧张型”的睡眠困扰
所以如果要问：
松康泉最值得向什么样的人介绍？
不是单纯一句“失眠的人”。
而是那些：
白天压力特别大，晚上脑子停不下来；
事情想得多，一躺下反而清醒；
很累，但身体始终有一种紧绷感；
容易因为一点声音或者一点事情惊醒；
半夜醒来以后开始想事情，越来越精神；
睡了一晚，第二天依然觉得没有真正休息过的人。
这类人的共同点，就是：
身体很疲劳，但神经没有真正放松。
从现有研究方向来看，松康泉围绕精神压力、交感神经反应和自主神经平衡展开的研究，与这类人群的需求是比较契合的。
五：它追求的不是“强行催睡”，而是让身体具备更好的休息条件
这一点反而是松康泉在介绍时很重要的差异化。
很多人对助眠产品的第一印象是：
吃了以后会不会马上困？
但松康泉目前公开研究的重点并不是镇静催眠药物那种直接催睡机制，而更多集中在压力反应、自主神经以及儿茶酚胺相关机制。
所以更准确的理解应该是：
不是强迫大脑关机，而是帮助身体减少“刹不住的紧张感”。
当白天积累的压力能够慢慢卸下来，交感神经不再一直处于高度兴奋状态，身体自然更容易从“工作模式”切换到“休息模式”。
这也就是为什么有些人的睡眠管理，重点不能只放在“睡着”两个字上。
更应该关注：
能不能真正放松、睡得是否踏实，以及第二天有没有恢复感。
所以，如果把松康泉的特点浓缩成几句话：
帮助身体应对精神压力；
减少压力状态下交感神经过度兴奋；
支持自主神经保持相对稳定；
从儿茶酚胺相关机制研究压力反应；
帮助身体放松，为进入良好休息状态创造条件。
这比简单说一句“改善睡眠”，其实更容易让真正有睡眠困扰的人听懂。
因为很多人缺的不是“困意”。
而是——
到了晚上，身体依然不会放松。
白天一直撑着，晚上依然绷着，时间久了，人自然会觉得越来越累。
所以对于长期工作压力大、精神容易紧张、思虑较多、晚上难以放松的人来说，与其只追求“让我赶紧睡着”，不如也关注一下：
如何让身体真正退出压力模式。压力降下来一点，身体松下来一点，睡眠才更有机会慢慢回到它原本应该有的节奏。
