Can Stress And Lack of Sleep Actually Trigger Heart Palpitations?

 

It is a common question, and the answer is yes.

For people living with arrhythmias, stress and poor sleep can directly influence heart rhythm.

What Is Happening In The Body

When you feel stressed, your body releases adrenaline and cortisol. These hormones increase heart rate and make the heart more sensitive to electrical signals.

That sensitivity can lead to:

  • Skipped beats

  • Sudden racing

  • More frequent episodes

Sleep disruption creates a similar effect. Instead of slowing down overnight, your system stays in a heightened state.

Why Sleep Apnoea Matters

One of the most significant links in the UK is between sleep apnoea and atrial fibrillation.

Interrupted breathing during sleep leads to repeated stress responses in the body, putting strain on the heart over time.

What You Can Do

Reducing triggers does not require drastic change. It starts with consistency.

Focus on:

  • Regular sleep patterns

  • Reducing late caffeine intake

  • Simple breathing techniques during stress

These changes support your heart’s stability in a very real way.

Small adjustments, done consistently, can reduce both the frequency and intensity of episodes.

Autism vs ADHD in Adults: Understanding the Overlap

Image
The differences between A utism and ADHD  in adults can be difficult to  recognise  because both conditions share similar surface symptoms. This overlap often leads to confusion or misdiagnosis.   Why the Symptoms Overlap   Both autism and ADHD can involve difficulties with attention,  organisation , social communication, and emotional regulation. However, the reasons behind these challenges are different. For example, autistic adults may miss social cues due to differences in social processing, while adults with ADHD may struggle in conversations because they are distracted or impulsive.   Common Overlapping Symptoms   Attention and focus difficulties can look similar, but autism may involve deep focus on specific interests, while ADHD often  shows up as  difficulty staying on task.   Social challenges can also appear in both conditions.
