When a loud and jarring alarm sound fills the room with the first light of morning, it doesn’t just wake you up; it can also shock your heart. Nowadays, millions of people set alarms at night to wake up early, which is considered a normal habit. However, medical experts believe that this habit is more stressful for the body and can negatively affect the heart and blood pressure.
Some Cardiologists Specialists Doctors says that a morning alarm is not just a sound but a ‘biological explosion’ inside the body. When you are in deep sleep (REM Sleep), your brain and heart are both in a calm state. Waking up suddenly to a loud noise makes the brain perceive it as a danger, which activates the body’s fight-or-flight system. Stress hormones like cortisol and adrenaline suddenly increase, causing the heart rate and blood pressure to spike in seconds. This situation may be manageable in healthy people, but it can be dangerous for those who already have high blood pressure, diabetes, or heart disease.
1. Sudden increase in adrenaline
As soon as you hear the alarm, the body goes into fight-or-flight mode. This suddenly increases the amount of stress hormones like adrenaline and cortisol, which increases blood pressure and heart rate, which can be dangerous for people with weak hearts.
2. ‘Sleep Inertia’ and pressure on the heart
The lowest blood pressure and heart rate are during deep sleep. Waking up suddenly to an alarm disrupts this peace and suggests it affects the heart and blood pressure as much as exercise.
3. Dangerous effect of the snooze button
Repeatedly pressing the snooze button causes the body to experience shock. This fluctuation puts more pressure on the heart’s arteries and can be harmful to heart health.
4. Risk of heart attack in the morning
Studies have shown that the rate of heart attacks and strokes is higher in the morning – this is due to disruption of the circadian rhythm and suddenly increased blood pressure in the body. A loud alarm can increase this risk even more.
1. Wake up with sunlight
Natural morning light reduces your sleep hormone melatonin and increases serotonin, which allows the body to wake up gradually. For this, leave the curtains slightly open at night so that sunlight can enter the room in the morning.
2. Slowly increasing volume alarm
If an alarm is necessary, choose a tone that gradually increases in volume – this prevents a sudden increase in blood pressure and heart rate.
3. ‘Sunrise’ alarm clock
Modern smart alarms are designed to gradually brighten up, allowing the body to prepare to wake up naturally.
4. Drink water before sleeping
Drinking a glass of water before sleeping causes the body to wake up on its own when it gets a signal from the bladder in the morning — this is an old home remedy.
5. Fixed bedtime
Going to sleep at the same time every day sets the body’s biological clock, reducing the need for an alarm.
