We tend to think that sleep deprivation on the weekdays can be compensated for by sleeping on the weekends, but according to one study, Pennsylvania State University Such beliefs turned out to be false.
Sleep deprivation throughout the week negatively impacts cardiovascular health indicators such as heart rate and blood pressure, and regaining sleep over the weekend won’t reverse these indicators, experts say.
“Only 65% of adults in the United States regularly get the recommended seven hours of sleep each night, and there are many studies suggesting that this lack of sleep is linked to cardiovascular disease in the long term. There is evidence,” said lead author Anne-Marie Chan. Associate Professor of Biobehavioral Health at Pennsylvania State University.
“Our study reveals a potential mechanism for this long-term relationship. Inflicting sufficient serial damage on cardiovascular health at a young age can predispose the heart to cardiovascular disease later in life.” may become.”
For this in-depth study over 11 days, experts selected 15 healthy men between the ages of 20 and 35. In the first three nights they were able to rest up to 10 hours and established a baseline sleep pattern.
Over the next 5 nights, participants’ sleep was reduced to 5 hours, followed by 2 nights of recovery phases, and again allowed up to 10 hours of rest.
The researchers measured the participants’ resting heart rate and blood pressure at two-hour intervals every day to assess the cardiovascular effects of this sleep pattern.
heart rate change
Researchers repeatedly monitor heart rate and blood pressure daily, which may explain the effect of time of day on these parameters.
For example, heart rate is naturally lower immediately after waking than during the day, so multiple measurements per day can account for this difference.
What researchers found
Analysis revealed that my heart rate increased by approximately 1 beat per minute (BPM) each day. It started at an average of 69 BPM and rose to around 78 BPM by the end of the study.
At the same time, systolic blood pressure increased by approximately 0.5 millimeters of mercury (mmHg) each day, from an average initial reading of 116 mmHg to approximately 119.5 mmHg at the end of the recovery period.
“Both heart rate and systolic blood pressure increased over the course of the day and did not return to baseline levels by the end of the recovery period,” said lead author David B. Reichenberger said.
“So, by the end of the study weekend, their cardiovascular systems had not yet recovered, even though there was an opportunity for additional rest.” , a longer sleep recovery period may be required.
“Sleep is a biological process, but it’s also a behavioral process that we can often control,” Chan says.
“Sleep not only impacts cardiovascular health, but it impacts many things, including weight, mental health, ability to focus and ability to maintain healthy relationships with others. And as we learn more and more about how sleep impacts everything in our lives, my hope is that sleep gets more attention in improving health.”
Learn more about sleep deprivation
Sleep deprivation refers to not getting enough sleep. It is either acute (short term) or chronic (long term). Here are some key points about sleep deprivation:
Effects on body and mind
Lack of sleep can cause mood swings, memory impairment, poor concentration, weak immunity, and poor decision-making.
physical health risks
Chronic sleep deprivation is associated with a variety of health problems, including obesity, diabetes, cardiovascular disease, and even a shortened lifespan.
mental health risks
It can also lead to mental health problems such as depression, anxiety, and paranoia.
There are many causes of sleep deprivation. It may be due to lifestyle choices, work-related issues, sleep disorders such as insomnia or sleep apnea, or other medical conditions.
accidents and injuries
Lack of sleep is associated with an increased risk of accidents, especially car crashes. Lack of sleep can slow a person’s reaction time as much as intoxication.
Sleep plays an important role in cognitive functions such as memory consolidation. Lack of sleep can impair learning and memory.
counteract the impact
The best treatment for sleep deprivation is getting enough sleep, but certain measures such as taking short naps, avoiding caffeine and electronic devices before bed, and maintaining a consistent sleep schedule are for the time being. Helpful.
The research will be published in a journal psychosomatic medicine.
