How to Lower Sleeping Heart Rate: A Comprehensive 2025 Guide

A lower sleeping heart rate is often considered a marker of good cardiovascular and overall health. It reflects the body's ability to rest, recover, and conserve energy during sleep.

However, many factors can elevate heart rate at night, including stress, poor sleep hygiene, underlying health conditions, and lifestyle habits.

This guide explores how to lower sleeping heart rate naturally, covering actionable strategies supported by scientific evidence. It also discusses what constitutes a healthy sleeping heart rate and when to seek professional advice.

What Is a Normal Sleeping Heart Rate?

According to the British Heart Foundation (BHF), a typical resting heart rate for adults ranges between 60 and 100 beats per minute (bpm) (British Heart Foundation, 2022). During sleep, heart rate usually drops by 10-20%, reflecting the body's shift into a parasympathetic (rest-and-digest) state.

Normal sleeping heart rate can vary by age:

• Newborns (0-1 month): 70-190 bpm

• Infants (1-11 months): 80-160 bpm

• Children (1-10 years): 70-130 bpm

• Adults (18+ years): 60-100 bpm

Elite athletes often experience much lower sleeping heart rates, sometimes dipping into the 40s, due to superior cardiovascular efficiency.

Why Sleeping Heart Rate Matters

Sleeping heart rate serves as an important marker of:

• Autonomic nervous system balance

• Recovery from daily stressors

• Sleep quality and depth

• Cardiovascular health

Persistently elevated heart rates during sleep have been linked to increased cardiovascular risk and disrupted autonomic regulation, according to research such as the Sleep Heart Health Study and findings published in the European Heart Journal.

Main Causes of Elevated Sleeping Heart Rate

Several factors can lead to a higher-than-normal heart rate during sleep:

• Stress and anxiety at night

• Poor sleep hygiene

• High caffeine or alcohol intake

• Dehydration

• Fever or infection

• Hormonal fluctuations (e.g., menopause)

• Underlying heart conditions (e.g., arrhythmias)

• Poor fitness levels

• Sleep disorders like sleep apnoea

Identifying the root cause is essential before implementing strategies to lower sleeping heart rate.

12 Evidence-Based Strategies to Lower Sleeping Heart Rate

Staying hydrated is an easy way to lower your sleeping heart rate

1. Improve Sleep Hygiene

Good sleep hygiene promotes deeper sleep cycles, where heart rate naturally falls. Strategies include:

• Maintaining a consistent sleep schedule

• Keeping the bedroom cool, quiet, and dark

• Reducing screen time an hour before bed

• Investing in a comfortable mattress and pillow

Research from the Sleep Research Society confirms that optimising the sleep environment can significantly improve heart rate variability and lower nighttime heart rate (Sleep Research Society, 2022).

2. Manage Stress and Anxiety

Chronic stress activates the sympathetic nervous system, keeping heart rate elevated even during sleep. Effective stress management techniques include:

• Meditation or mindfulness practice

• Deep breathing exercises (e.g., box breathing)

• Journaling before bed

• Cognitive behavioural therapy (CBT) for persistent anxiety

  
  

3. Limit Stimulants in the Evening

Caffeine and nicotine are stimulants that can increase heart rate and delay the body's natural wind-down process. It is advisable to avoid caffeine after mid-afternoon and refrain from nicotine use entirely.

A study published in the "Journal of Clinical Sleep Medicine" found that caffeine consumption within six hours of bedtime significantly disrupts sleep patterns and increases resting heart rate.

4. Reduce Alcohol Consumption

While alcohol might initially induce drowsiness, it disrupts REM sleep and elevates heart rate during the second half of the night.

5. Maintain Optimal Hydration

Dehydration thickens the blood and forces the heart to work harder, increasing heart rate.

Drinking adequate water throughout the day and having a small glass of water before bed (without overdoing it) supports cardiovascular function during sleep.

6. Engage in Regular Aerobic Exercise

Regular cardiovascular exercise improves resting heart rate by strengthening the heart muscle and improving efficiency.

Activities such as walking, cycling, and swimming have been shown to significantly lower resting and sleeping heart rates over time (European Heart Journal, 2022).

7. Incorporate Relaxation Exercises Before Bed

Specific relaxation techniques designed to lower heart rate before bed include:

• Progressive muscle relaxation (PMR)

• Yoga nidra (a guided form of meditative sleep)

• Gentle stretching

Practising these techniques can prepare the autonomic nervous system for sleep and facilitate a natural heart rate decline.

8. Optimise Bedroom Temperature

The body's core temperature naturally falls during sleep. A cool bedroom environment (around 16-18°C) helps facilitate this process.

Higher room temperatures have been linked to increased heart rate and disturbed sleep.

9. Address Sleep Disorders

Conditions such as sleep apnoea cause intermittent drops in blood oxygen levels, prompting sudden spikes in heart rate throughout the night.

If symptoms like loud snoring, frequent awakenings, or excessive daytime fatigue are present, it is advisable to seek medical assessment. Treatments such as CPAP (Continuous Positive Airway Pressure) therapy can help normalise heart rate patterns during sleep.

10. Follow a Heart-Healthy Diet

Nutrient-rich diets that support heart health can lower resting and sleeping heart rates.

Key dietary components include:

• High intake of fruits and vegetables

• Omega-3 fatty acids (e.g., from flaxseeds or fish oil)

• Low sodium levels

• Adequate magnesium and potassium intake

  
  

11. Maintain a Healthy Weight

Obesity places additional strain on the heart, often leading to higher resting and sleeping heart rates.

Gradual, sustainable weight loss through a combination of diet, exercise, and behaviour modification has been shown to improve nighttime cardiovascular function.

12. Consider Supplements (Under Medical Advice)

Some natural supplements may support heart rate regulation, including:

• Magnesium glycinate: Supports muscle relaxation and heart rhythm (Abbasi et al., 2012).

• Omega-3 fatty acids: Promote heart health (Mozaffarian & Wu, 2011).

• L-theanine: An amino acid linked to relaxation and reduced heart rate during stress (Nobre et al., 2008).

It is important to consult a healthcare provider before starting any new supplement, particularly if taking prescription medications.

When to Seek Medical Advice

While lifestyle changes can significantly influence sleeping heart rate, certain signs warrant professional evaluation:

• Persistent sleeping heart rate above 100 bpm

• Irregular heartbeat during sleep

• Symptoms of breathlessness, chest pain, or frequent awakenings

• Known history of cardiovascular disease

Early intervention can help address underlying issues and prevent complications.

Conclusion: The Path to a Lower Sleeping Heart Rate

Lowering sleeping heart rate is not about quick fixes but about establishing consistent habits that support cardiovascular health, stress reduction, and high-quality sleep.

Incorporating techniques such as improved sleep hygiene, regular exercise, stress management, and heart-healthy nutrition can yield profound long-term benefits.

For those experiencing persistent issues, seeking medical advice ensures that potential underlying conditions are properly addressed.

A healthy sleeping heart rate reflects a body in balance — one that rests, recovers, and rejuvenates fully during the night.
