                      Erratic Sleep Puts Heart Health At Risk

                      3/23/2023

                      Stay on schedule with a full night of sleep for your best physical and mental health

                      MalladiWe’ve all experienced the tiredness and lack of clarity that comes from a sleepless night, but a study published last year by the Journal of the American College of Cardiology Foundation found that sleep schedule inconsistency is also a risk factor for heart disease. Srikanth Malladi, M.D., board-certified internal medicine physician with Mat-Su Medical Group, is making sure patients know how important it is to establish a regular pattern for going to bed and waking up.

                      The cardiovascular system exhibits strong circadian rhythms, biochemical, physiological and behavioral processes that rise and fall during the 24-hour day, to maintain normal functioning. The sleep/wake cycle is another circadian rhythm and the study found that individuals with the most irregular sleep duration or timing had more than twice the risk of developing cardiovascular disease compared with individuals who had the most regular sleep patterns. Physicians are now more likely to recommend sufficient sleep as a heart health prevention action on top of physical activity and healthy diet.

                      “Sleep consolidates memory, improves concentration and well-being, also a good night’s sleep helps control your blood pressure,“ said internist Dr. Malladi, “An occasional night of tossing and turning is fine, but your health suffers if you have a lack of sleep that goes on for too long.”

                      The National Sleep Foundation has identified that from age 18 to 64 we need 7 to 9 hours of sleep, and at 65 or older we need 7 to 8 hours of sleep. Children and younger people have a need for more hours.

                      This time is needed so the body can perform a number of vital functions that support the health of your body and brain. Three primary functions are repairing tissue, fighting off infection and processing memories of experiences from your day.

                      Higher variability in sleep duration or timing is associated with higher blood pressure, dysregulated blood lipids and insulin resistance that can lead to diabetes. Insufficient sleep can affect your body in other ways too.

                      • Immune functioning is compromised as your body produces fewer antibodies so you’re more likely to get sick and the body has fewer resources to stave off illness, including cancers.
                      • Impulse control and appetite hormones can become unbalanced, promoting overeating and obesity.
                      • Mental functioning can be less for problem solving, reasoning, organizing, planning and executing plans.
                      • Learning is affected in all stages – your ability to encode new information, to consolidate and absorb the information and make new connections, and ability to remember and retrieve the information.

                      “If you are tired during the day, needing a nap or wake up in the morning unrefreshed it could be due to sleep apnea”, said Dr. Malladi.

                      Many things can cause difficulties sleeping and sleep deprivation, including stress, sleep apnea and chronic insomnia. Insomnia is often a symptom of stress or anxiety disorders that can make it difficult for you to relax enough to fall asleep and sleep soundly. Your physician can help diagnose whether you could benefit from medication or behavioral therapy or if a thorough sleep study is needed.

                      If you would like an appointment with Dr. Malladi or one of our primary care physicians call 907-861-6700 or visit https://www.matsumedicalgroup.com/doctors-providers to be connected with one of Mat-Su Medical Group’s qualified primary care or internal medicine physicians.
