Poor sleep contributes to heartdisease risk by elevating blood pressureand inhibiting insulin resistance

Increased insulin resistance leads to central obesity causing diabetes, hyper/dyslipidemias, atherosclerosis, hypertension, heart attack, stroke and renal failure Prof Emeritus Lt Gen Mahmud Ahmad Akhtar Former Surgeon General/DG Pak Armed Forces

Sleep is very important for health, both physical and mental. Poor sleep curtails life span. Regular exercise is also important for health. New studies have shown that exercise may help counteract consequences of poor sleep.In an ideal world, one would be better off to get ample sleep and ample exercise. A new study suggests that exercise could potentially help counteract the health consequences of not getting a proper amount of sleep. There may be a tendency to skip exercise to take rest after a poor sleep.

The new research builds upon a large body of work showing how critical areas both for sleep and fitness are pertained to overall health. Various studies show that healthy amount of each individual are linked to increase longevity and at least one suggested that sleep problems tended to increase the chances that a subject would die during the follow up period but that regular exercise help that eliminate the risk.

A team of researchers in China wanted to better understand the protective power of exercise, so it examined data collected in the United Kingdom from over 92000 adults between the ages of 40 and 73. Participants spent a week between 2013 and 2015 wearing a wrist band that measured how much they exercised and slept, which the researchers used as an indication of their lifestyle habits.

The researches then tracked the health outcomes of the participants years later. Predictably those who get partly sleep or those who slept too much (which itself can be a problematic and hardly exercised were those are generally more likely to die during that period) including from issues such as cardio-vascular disease and cancer but the researchers uncovered a surprising trend in the data. People who exercised regularly did not have an increased risk of death, even they only slept less than six hours each night.

The study suggested that completing 150 minutes of moderate or vigorous physical activity every week might negate some of the health consequences associated with sleeping too much or too little said the director of the center for Sleep and Circulation Medicine at the Affiliated Brain Hospital at Guangzhou Medical university and an author of the study.
“Doing something is better than doing nothing” he said. For example, regular short walks ride on a stationary bike could pay off.

The researchers on the new study theorized that working out might help balance out the effects of unhealthy sleep by combating inflammation or possibly helping regulating metabolism and sympathetic nervous system activities, Dr Zhang said. It is also possible that poor sleep contributes to heart disease risk by elevating blood pressure and inhibiting insulin resistance, said Dr Virend of Somers a Cardiologist who studies effects of sleep loss at the Mayo clinic. Exercise might counter this by regulating blood pressure and increased insulin resistance. Increased insulin resistance leads to central obesity causing diabetes, hyper/dyslipidemia, atherosclerosis, hypertension heart attacks, strokes, renal failures, hepatic steatosis, cirrhosis, hepatoma and cancer etc.

One of the most compelling ways exercise interplays with sleep is in the brain, said Jenifer-Heisz, an associate professor at McMaster University and the author of “Move the Body, Heal the Mind”. This is partly because a hard workout prods our cells to produce adenosine which functions as a natural sleep aid. The more adenosine is generated throughout the day, the more restful and restorative sleep becomes- which could counteract a night or two of patchy test.

Still, that does not mean people should sacrifice rest in order to exercise said Tianyi Huang Associate Professor of Medicine at Harvard Medical School who has studied sleep and Heart health. People who cannot get sufficient health are unlikely to have energy to stay active during the day, he said, especially if the lack of sleep stems from a hectic work schedule. Past research has also shown that morning workouts may influence body differently than evening ones.

“What this tells us is that if one cannot manage sleep optimally right now, they should schedule time to get moderate to vigorous physical activity said Dr Donald Lloyd Jones, a former President of the American Heart Association and the chair of the Preventive Medicine at Northwestern University Fienberg School of Medicine.

Promotion of Health and Prevention of diseases (Preventive Medicine) is in to the problem of Public health. It is cost effective as it costs very little in immunization/ vaccination etc. It is tragic that our health policy is lop-sided. Over 2/3rd of meagre health funds is spent on secondary and tertiary health particularly in building and running disease palaces, whereas, it should be the opposite. There is a separate ministry for the secondary/ tertiary care in the largest province Punjab. The policy is Americanization. American health-care system is spending the highest amount on health care system and placed at 56th position among the rich 61 countries with the worst health outcomes, even worse than the Eastern European countries spending much less. Universal health care system started in Geruang by Bismarck, Meig in Japan. Scandinavian Nordic countries, UK in the 19th century and other countries have best outcomes with less spending.

Pakistan is the only low/ mid income country not following the WHO expert committee Essential Drug System and using the irrational drugs, robbing the country and its people of health and meagre wealth inspite of accepting the WHOs Essential Drug List.
Pakistan’s health parameters are not only lowest in the region including Nepal and Bhutan, but also in the world except the war-torn Afghanistan and Syria due to its bad policies. KPK claimed to have installed the most modern CT scan/ MRI machines at Peshawar under the guidance of an American Trained Physician. The scribe has been writing for following the imported Primary care system but to no avail.
