Another New Study Proves How Important Sleep is to Our Health

In recent years researchers have focused on the many benefits of a good night’s sleep. Now a new study   appearing on the Medical News Today website, reports even three nights in a row of poor sleep can adversely affect our health. The study from Uppsala University examined how lack of sleep affects the body, with a focus on heart health. Their findings concluded that biomarkers associated with inflammation and heart health increased after just three nights of little sleep.

Cheng-Han Chen, MD, a board-certified interventional cardiologist and medical director of the Structural Heart Program at MemorialCare Saddleback Medical Center, said the results are not surprising as poor sleep can negatively impact numerous health factors. In addition to cardiovascular health, he explains it can negatively impact endocrine and immune functioning.

With an abundance of research regarding the importance of sleep, what can people who have problems getting to sleep or sleeping through the night do to improve sleep patterns? Suggestions include adopting better sleep habits like reducing nicotine and caffeine along with limiting blue light devices several hours before bedtime, adopting routine bedtimes, and keeping the room dark.

Using a sleep tracker may also help you to understand your sleeping behavior and detect trends in your sleep cycle; and if appropriate, the data can be shared with your doctor. Sleep trackers generally use an instrument called an accelerometer to track movement and an algorithm interprets the data to provide an overview of a person’s sleep patterns. Some devices also include a heart rate monitor. A 2018 study suggests that sleep trackers can accurately track total sleep time and time spent in bed. However, while not as effective as sleep studies in detecting when people wake up, researchers say “sleep trackers are a valid way for people to track their sleeping habits and note that these devices may become more accurate as technology advances.” 

The devices can also help identify possible health issues such as sleep apnea, lung disease, heart disease and diabetes. It is important to note sleep disturbances can play a role in the onset or exacerbation of various mental health conditions like anxiety, depression and bipolar disorder. Talk to your healthcare provider about ongoing sleep problems.
