HRV as your longevity compass

Die Verbindung zwischen Herzratenvariabilität und Longevity

Your heart rate variability, also known as HRV, shows how flexibly your heart reacts to different stresses. Measured in milliseconds (ms), it analyzes the small time intervals between two heartbeats. High HRV shows that your body can efficiently adapt to different situations such as physical exertion, stress or recovery.

A simple example: when you are relaxed, your heart beats more slowly and regularly. When you are stressed or exercising, it speeds up. So the variability is not that your heart beats irregularly, but how quickly it can switch between different states of stress.

"As you get older, you need to be more aware of what your body can and cannot do. And that's part of what HRV can help you understand.”
Joel Jamieson

This adaptability is what makes HRV so valuable. It indicates how healthy the autonomic nervous system is and how well the body can handle stress and recover. High HRV is often associated with better fitness, more effective stress management, and a longer, healthier life.

“Over the past few decades, HRV has been shown to be a strong, independent predictor of morbidity and all-cause mortality.”

So, your goal should be to have a resilient heart – like a dancer who always moves to the beat of the music without getting out of sync.

What does your HRV say about you?

HRV gives you deeper insights into the state of your body and your health. It is a powerful marker of how well your body can process stress and recover.

High HRV: A sign of resilience, good adaptability, and effective recovery. It indicates that your body can handle stress well and that your nervous system is in balance.
Low HRV: This can indicate chronic stress, insufficient sleep or overtraining. It shows that your body may have difficulties recovering or adapting to challenges.

Your HRV is particularly valuable when observing long-term trends. It helps you recognize behavioral patterns, e.g. how sleep quality, nutrition or training affect your recovery.

Ideal HRV values: always individual

You can use your HRV value to better adapt your training plan to your current state. A high HRV value shows that your body is well recovered and can handle more intense training well. If your value is low, you should focus on lighter activities because your body needs more recovery.

However, HRV is very individual and depends on age, fitness, lifestyle, sleep and stress levels. There is no such thing as a universally good or bad value, only what is normal for you.

That's why it's important to monitor your own HRV trends to understand how your body responds to stress and recovery. For a 50-year-old, a typical HRV value often lies between 20 and 70 milliseconds (ms), with higher values generally being better.

“For example, if your morning HRV is more than one standard deviation from your average, it probably means you've been under more stress and are less recovered.”
Peter Attia

However, this range only serves as a rough guide, as HRV is strongly influenced by individual factors. What is crucial is how your value develops over time. If it remains stable or increases, this shows that your body is able to deal with stress and recovery well. If it decreases permanently, it could indicate that you should pay more attention to recovery and stress management.

Why is HRV important for your healthspan?

HRV is an important indicator for extending your health span – that is, your healthy and active years.

It is closely related to key health factors such as:

Cardiovascular health: People with high HRV have a lower risk of cardiovascular disease.
Stress management: High HRV shows that your body is coping well with tension and relaxation.
Inflammation and cell health: Less inflammation and healthier cells mean that the body ages more slowly.

In short, higher HRV helps the body to stay flexible, resilient, and healthy – and that's the basic requirement for a longer healthspan.

HRV for relevant aspects of everyday life

HRV can help you to better manage your daily life and balance your recovery and stress phases. Here are a few practical approaches:

Training planning: A high HRV indicates that your body is ready for intense workouts. A low HRV, on the other hand, shows that your body needs more rest. Plan your activities accordingly.
Stress management: If you notice that your HRV is dropping for several days, it's time to pay more attention to stress reduction and recovery.
Analyze long-term trends: By measuring your HRV regularly, you can determine which lifestyle factors may have a positive or negative influence, such as sleep, diet or exercise patterns.

How can you improve your HRV?

The best thing about HRV is that it can be positively influenced by simple habits. Here are some strategies to sustainably increase your HRV:

Zone 2 training: This low-intensity endurance training improves mitochondrial health, which is directly related to higher HRV. Zone 2 training boosts the efficiency of your energy metabolism and strengthens your heart.
Stress reduction: Techniques such as meditation, yoga or breathing exercises activate the parasympathetic nervous system and help your body to relax. The 4-7-8 breathing technique is an easy way to increase your HRV.
Optimize your sleep: A consistent sleep schedule and at least 7-8 hours of sleep per night are crucial. Avoid caffeine and alcohol before bed to improve sleep quality.
Diet: Reduce foods that promote inflammation and incorporate nutrient-rich, anti-inflammatory foods such as fruits, vegetables, and healthy fats into your diet. These include, in particular, omega-3 fats.
Plan for recovery: Take regular breaks to recharge your batteries. Active recovery, such as a relaxed walk or light stretching, supports your nervous system. Regeneration is an important key to your longevity journey.

How can I measure my HRV value?

The gold standard is actually a lab ECG, as it provides the most accurate data. However, for everyday use, a few selected wearables are sufficient to reliably measure HRV and identify trends. A chest strap is the most accurate way to measure HRV outside of a lab because it provides precise data directly from your heart. While the latest Apple Watch offers convenience and continuous measurement, it is less accurate than a chest strap. Here are some of the best options in terms of ranking:

Polar H10 Chest Strap: Accurate and best for athletes. It measures electrical signals, which provides the most accurate data.
Apple Watch (latest models): Offers HRV measurements, along with additional health metrics such as sleep tracking and heart rate monitoring.
Oura Ring: Ideal for sleep monitoring and long-term analysis. The ring measures HRV during sleep and provides comprehensive data on your recovery.
WHOOP Band: Designed for athletes to track exertion and recovery. It gives you daily recommendations on when to rest.
Garmin watches: These wearables combine HRV measurement with other fitness metrics. They are particularly useful for outdoor activities such as running or cycling.

It is important that you use your wearable consistently and take the measurement at the same time of day if possible, e.g. in the morning after waking up. This way, you can identify trends and take targeted measures to improve them.

HRV for your personal longevity journey

For your longevity journey, HRV is a kind of compass that can show you the way to more balance, resilience and health. The value shows you how well your body can deal with the challenges of everyday life – and how you can optimally support it.

By regularly measuring your HRV and using the data, you can work specifically on your fitness, sleep and stress management. Wearables make it easy to track your progress and adjust your actions.

Your longevity journey begins with a heart that stays flexible – so embrace movement, relaxation and mindful choices to actively shape your life. Your body will thank you for it with energy and endurance!
