Why does my heart race when I hear loud fireworks?

Adrenaline is your body's response to loud fireworks, which can make your heart beat faster and raise your blood pressure.

How Loud Firecrackers Impact Heart Rate in Pregnant Women

Imagine relaxing at your home, but a sudden burst of crackers startles you, as your heart skips a beat. Your breathing may become quick, and some may even feel dizzy. This reaction is a natural response to the loud noise and may be a problem if you are pregnant.

What Happens to Your Heart During Pregnancy?

Your body undergoes many changes related to your cardiovascular activity during pregnancy.

Your heart rate may increase by about 10–20 beats per minute.
Blood volume rises by up to 50%.
Blood vessels expand to deliver oxygen and nutrients to your baby.

These changes indicate your heart is working harder, and sudden stress can make your heart beat faster.

How Do Loud Firecrackers Affect Heart Rate?

Your body releases adrenaline when you hear a sudden loud sound. This stress hormone is responsible for the fight or flight response in your body. It may also cause the following reactions:

Increased heart rate, as your heart pumps faster to prepare to take action.
Blood vessels tighten temporarily, leading to higher blood pressure.
Without realising, you may start breathing heavily.
If you startle repeatedly, it may cause temporary anxiety or stress.

These effects may pass quickly for most people, but not during pregnancy. Such stressful reactions can last longer and may affect your comfort, mood, or sleep.

Why Are Pregnant Women More Sensitive to Loud Noises?

The following factors may make you sensitive to loud noise during pregnancy.

Hormonal changes can make you sensitive to the stress response.
Increased blood flow makes your heart become more reactive.
Fatigue and anxiety make it harder to handle sudden loud sounds.
Protective instincts may cause you to react strongly to unexpected threats.

Pregnancy can make loud sounds intolerable even if you were not sensitive to them before.

Can Firecracker Noise Harm Your Baby?

Occasional noise exposure is not harmful, but continuous exposure to sounds more than 85 decibels can raise your stress hormones. If cortisol or adrenaline gets high, they can impact your baby in several ways.

Your baby’s heart rate (studies show slight changes when mothers are startled).
Your blood pressure may influence blood flow to the placenta.
Your emotional well-being can lead to restlessness or poor sleep.

These effects are temporary, but it is best to avoid prolonged loud noises in the last trimester of your pregnancy.
