Sleeping too much or too little has risk. /photos/mart3ll/ 255289520

Heart health is tied to how much sleep you get.  There is an optimal amount of sleep: 6-8 hours per night.

Those who slept less than 6 hours per night had twice the risk of heart attack or stroke compared to those who slept 6 to 8 hours per night.  Studies have linked insufficient sleep with

  • hyperactivation of the sympathetic nervous system,
  • glucose intolerance,
  • an increase in cortisol,
  • increase in blood pressure,
  • decreased variability in heart rate,
  • disruption of hypothalamic axis, and
  • increase in inflammatory markers.                               Wow!  All bad things!

Those who slept more than 8 hours per night had a twofold increased risk of heart pain (angina) and an increased risk of coronary artery disease (which may lead to heart attack). It is postulated that patients who sleep more than 8 hours per night may do so because of an underlying condition like lung disease, diabetes, or low socioeconomic status which all could contribute to cardiovascular risk.

Hope this helps.
