The dangerous effects of alarm clocks are named: from sleep disturbances to heart disease

Forced awakening has been associated with unpleasant consequences for the body

An alarm clock on your phone, as scientists have found, can put your health at risk. According to research, waking up with it can lead to hypertension and increases the risk of heart attack or stroke.

Researcher Yeonsu Kim, as reported by the University of Virginia publication UVA Today, compared the morning blood pressure surge during natural and forced awakening. Of course, the results of this experiment should be tested in a larger sample, but her study found that those who woke up to the sound of an alarm clock had a 74 percent higher morning blood pressure spike than those who woke up on their own.

< p>This study suggests a link between short sleep duration, forced awakening and morning blood pressure surges. Scientists emphasize that adults with cardiovascular disease may experience adverse effects from morning blood pressure surges when they get little sleep and wake up abruptly.

Study participant mechanical engineering graduate student Daniel Lee said he was usually always woken up by his alarm, and his sleep test results showed he was an «above average» sleeper and could fall asleep easily. He said waking up the second night after only five hours of sleep to his phone's preset alarm was unpleasant.

After research, Lee noted that he «isn't going to set the alarm and will try to wake up naturally when he has more time.» , for example, on weekends.»

Researchers conducted an experiment to prove that when the morning surge in blood pressure is excessive, it can activate the fight-or-flight response, which puts stress on the heart, which pumps blood harder and harder, and the brain releases adrenaline. It can cause fatigue, shortness of breath, anxiety, and, if worsened, headaches.

Data also showed that people who sleep less than seven hours a night are at increased risk of stroke or heart attack due to increased activity nervous system.

The University of Virginia study builds on existing experiments on the best way to wake up, conducted in 2020. It then showed that waking up to melodious sounds, such as a song you can hum, helps people avoid persistent sleepiness, which can last up to two hours after waking up.

In another study conducted in 2021, researchers Science has discovered that exposure to light in the morning causes your body to slow down the production of melatonin, helping people wake up and stay alert.
