Low HRV Symptoms: 7 Shocking Reasons Why Your HRV Is So Low & How to Fix It
The most important physiological indicator is heart rate variability (HRV), which will indicate the state of your autonomic nervous system (ANS), the body system that regulates automatic processes, including heart rate, digestion, and breathing. HRV is unlike the heart rate, which only gives one value, i.e., the rate at which your heart beats. (see more)
This difference does not occur as an incidental change; it represents the degree to which your body is responsive to stress, to physical exercise, and to emotional stress. In terms of HRV, the low values are commonly correlated with a set of symptoms that can demonstrate a lack of cardiovascular well-being, inadequate rest, and some disorder in your nervous system.
We will go into the low HRV symptoms in this comprehensive guide, understand why you have a low HRV symptoms, and see how you can improve it to have better health, fitness, and performance. Knowing your HRV is essential to enhance your health, cope with stress, and recover better. Listening to the low HRV symptoms and striving to improve them, you will achieve a lot in relation to your physical and psychological health.
What Does Low HRV Mean?
HRV is the measurement of the difference in time between heartbeats, which is also regulated by the autonomic nervous system (ANS), which is further subdivided into two components: (see more)
Sympathetic Nervous System (SNS):
The fight or flight mechanism that accelerates your heart rate, to prepare your body to move or to be stressed.
Parasympathetic Nervous System (PNS):
The “rest and digest system slows down the heart rate and produces relaxation and recovery.
Low HRV symptoms mean that the sympathetic nervous system (SNS) is active, meaning your body is in a more stressed, tense state. On the other hand, a high HRV is usually linked to a strong parasympathetic nervous system (PNS), i.e., you are more relaxed and recovered.
A low HRV symptoms can be an indicator that your body is not adequately decomposing exercise or stress, or that your autonomic nervous system is unable to find a balance. That is, low HRV symptoms may be a symptom of heart disease, lack of res,t and diminished stress management capacity.
Low HRV Symptoms: How to Recognize Them
In the case of low HRV symptoms, it occurs in both physical and emotional symptoms. The symptoms of low HRV can influence your energy levels, the level of stress, and your health. The following are some of the most prevalent low HRV symptoms that you need to watch out:
1. Fatigue and Tiredness
Increased fatigue is one of the initial symptoms of having low HRV. Even after a good night’s sleep, you may feel tired than normal; this could be an indication that your body is not recovering properly. Low HRV symptoms (chronic) make the body rest, and result in exhaustion, which does not appear to be corrected, no matter how much you are able to do.
2. Difficulty Recovering After Exercise
This may also be another physiological indicator of low HRV symptoms in case you experience an inability to recover after even a light exercise or feel sore longer than anticipated. A low HRV indicates that your body is not efficiently moving to a restful position after physical exercise, and you are feeling fatigued and fail to recover promptly.
3. Elevated Resting Heart Rate
A more frequent low HRV symptoms is an elevated resting heart rate (RHR). When your autonomic nervous system is out of balance, your heart must beat faster to provide the body with sufficient oxygen and nutrients. It may occur when you are in chronic stress, have not recuperated well after recent physical exercise, or when your cardiovascular system is damaged.
4. Increased Stress and Difficulty Managing Stress
Having a low HRV symptoms can make it more difficult to handle stress. The reason is that your sympathetic nervous system is more active and the parasympathetic nervous system, which enables you to overcome stress, is harder to engage. Consequently, you will be more anxious, irritated, or even emotionally unstable.
5. Poor Sleep Quality
Poor sleep quality is associated with low HRV. Individuals who have low HRV might struggle to reach restful periods of sleep, and thus they can have a sense of exhaustion or unconsciousness after a full night of sleep. Low HRV symptoms may also result in insomnia or wakefulness in the middle of the night, so you cannot get the rest that you need.
6. Impaired Immune Function
The immune functioning has been proven to be adversely impacted by low HRV. Given the fact that HRV is associated with the autonomic nervous system, which governs inflammation and immune response, low HRV symptoms may cause a depressed immune system, which leaves you vulnerable to illness and disease.
7. Mood Swings and Anxiety
Low HRV symptoms are also associated with emotional self-regulation being affected, and the result could be a greater number of mood, irritability, and anxiety swings. This is due to the fact that low HRV is linked to an overactive SNS, and this may result in your body staying in a stressed state despite the absence of an imminent threat.
Why is My HRV So Low? Understanding the Causes
Low HRV symptoms can be caused by a number of factors, and to solve low HRV, it is necessary to know the reasons why you have low HRV. These are some of the most prevalent causes of having a low HRV symptoms than expected:
1. Chronic Stress
Chronic stress is one of the major causes of low HRV. Your sympathetic nervous system (SNS) is hyperirritable when you are under extended stress, which reduces HRV. Work, relationships, and any other life aspect can cause chronic stress, and it can deeply affect your physical and emotional health.
2. Overtraining
Overtraining is the condition of overworking your body without sufficient time to rest. Other athletes or people involved in high-intensity training without proper rest may lose HRV. Overtraining causes burnout and causes your body to require more time to restore its health between sessions, so it becomes difficult to keep your body in a healthy HRV.
3. Poor Sleep
Sleep is essential for HRV. Lack of sleep or poor quality sleep may result in the inability of the parasympathetic nervous system (PNS) to activate, resulting in reduced HRV. Disruption of sleep, e.g., insomnia or abnormal sleeping, further disrupts recovery and aggravates HRV with time.
4. Unhealthy Diet
Unhealthy eating habits that are characterized by lots of processed foods, sugar, and unhealthy fats can result in low HRV symptoms. These foods leave the body with increased inflammation and oxidative stress, which can decrease HRV. The unhealthy diet exerts more stress on the body and the PNS finds it difficult to go do and be recover.
5. Dehydration
Dehydration may have a drastic impact on your HRV. Water is important in numerous physiological functions of the body, including those that are controlled by the autonomic nervous system. In case of dehydration, the body is under more stress; hence, the HRV decreases.
6. Underlying Health Conditions
Low HRV symptoms can be caused by some of the health conditions, including heart disease, hypertension, diabetes, and chronic inflammation. Such conditions stress your cardiovascular system and autonomic nervous system, which causes decreased HRV and lack of good health.
7. Age
Your HRV reduces naturally with age. Your autonomic nervous system becomes less effective at balancing the SNS and PNS as you get older, and this is why older people are likely to have lower HRV. Nonetheless, lifestyle factors, including exercise, stress management, and a healthy diet, can be used to reduce this decrease.
What Is a Good HRV Score?
The good HRV score may differ significantly due to a number of reasons, such as age, sex, fitness level, and well-being. In most cases, increased HRV levels represent an indication of good cardiovascular condition and effective recovery.
HRV Normal Range by Age
The range of HRV is dependent on age, with the young ones having higher HRV than the elderly. The following is a rough HRV graph by age so that you can make sense of where your HRV is compared to the average:
| Age Group | Average HRV (ms) | Below Average HRV | Above Average HRV |
| 20-29 | 55-100 | < 55 | > 100 |
| 30-39 | 45-90 | < 45 | > 90 |
| 40-49 | 40-85 | < 40 | > 85 |
| 50-59 | 35-80 | < 35 | > 80 |
| 60-69 | 30-75 | < 30 | > 75 |
| 70+ | 25-70 | < 25 | > 70 |
What is Considered a Good HRV Score?
The normal range of HRV is usually within the high stay of your age. A score of higher than 80 in most adults is an indication of resilience, cardiovascular fitness, as well as good recovery. When you have a good HRV score, it indicates that your body is capable of properly managing stress and your body can easily bounce back after a physical job.
Low Resting Heart Rate But Not Fit: What Does It Mean?
When you get a low resting heart rate (RHR) but do not feel fit, then this may be a sign of an imbalance in your HRV. Although the low rate of resting heart rate is commonly linked to sportspeople or people with great fitness, this does not necessarily imply that your body is in optimal condition.
Indeed, there is a possibility that you have low HRV symptoms even when your resting heart rate is low, which means you do not recover, you experience stress, or even have other health issues. A low resting heart rate that does not indicate a sense of fitness implies that you have an efficient heart rate at res,t but your body is not bouncing back well to the daily stresses or physical activities. Following the HRV and resting heart rate will provide you with a better understanding of cardiovascular health and fitness.
How to Improve Your HRV
Provided that you have low HRV symptoms or simply wish to maximize your HRV, there is a number of strategies that you can follow. Here’s how to improve HRV:
1. Get Enough Sleep
One of the most significant factors for enhancing HRV is sleep. You want to achieve 7-9 hours of good sleep a night to get your body to rest. Adequate sleep also stimulates the parasympathetic nervous system, which increases HRV.
2. Exercise Regularly
Regular cardiovascular exercise like running, cycling or swimming is necessary to enhance your cardiovascular fitness and HRV. But do not overtrain; too much exercise without sufficient rest may reduce HRV.
3. Practice Stress Management
Deal with stress with yoga, meditation, deep breathing, or mindfulness. These activities stimulate the parasympathetic nervous system to enhance HRV and make your body better able to manage stress.
4. Eat a Balanced Diet
Healthy HRV could be supported with the help of a healthy diet consisting of fruits, vegetables, whole grains, and lean proteins. Omega-3 fatty acids and antioxidants aid in decreasing inflammation and raising HRV through the maintenance of a healthy balance in the autonomic nervous system
5. Stay Hydrated
The dehydration may reduce HRV, and therefore, it is necessary to drink as much water as possible during the day. The hydration prevents the dysfunction of the autonomic nervous system, which promotes recovery
Conclusion
The Low HRV symptoms are a good sign that your body is either failing to cope with stress, failing to recover after a physical activity, or lacking optimal cardiovascular functioning. This cannot be overlooked because HRV is central to the study of how suitably your body responds to any physical or emotional difficulty.
Low HRV symptoms remain a regular occurrence that may indicate that your autonomic nervous system (ANS), driving the effect of heart rate, stressful responses, and recovery, is dysfunctional. This imbalance can influence the functionality of your body in its daily activities, stress coping, and adequate post-exercise recovery, which may cause you to be tired, sleep poorly, and develop long-term health issues.
The meaning of HRV is important in deciding the underlying causes of low HRV symptoms and the effects on different parts of your health. A low HRV symptoms are a sign that your body is being overstrained, failing to recover well, or it is possibly not adapting well to physical activity or emotional stress.
It is a measure of the quality with which your body can alternate between the sympathetic nervous system (SNS), which is the one involved in the fight or flight response, and the parasympathetic nervous system (PNS), which is the one involved in the rest and digest process and restoring the body. Good health and strength are a matter of a healthy balance between these two systems.
A comprehensive strategy that includes the optimization of sleep, stress management habits, a healthy diet, and exercise will not only increase your HRV but also positively affect your whole quality of life. Monitoring your HRV will allow you to have the information necessary to evaluate your progress, make effective changes, and to make sure that your body is in a state of balance and rest. By working on the enhancement of HRV, you will have a healthier and stronger body that can cope with stress, recover effectively, and perform optimally in every aspect of your life.
