Morning exercise is bad for your heart

It is a known fact that over-exercising harms the heart. Many studies have indicated that the limit of 1 hour a day is the best when it comes to exercise. But does the time of the day matter?

Exercising in the morning – the problems

Many times, when one exercises in the morning without sufficient sleep, there are chances of fainting. Mornings are also the time when a person’s body has not received food for more than 8-10 hours. This drops sugar levels in the blood making the person more prone to exhaustion. The body also shifts into reserve mode, resulting in ketosis and loss of lean muscle mass. All these in turn lead to cramping, nausea and vomiting. Since body fat, blood sugar levels, lean muscle mass and sleep are all related in some way or the other to the heart, there is interest to find out whether exercising early morning causes heart problems.

Latest research findings

The European Journal of Applied Physiology, in its January 2010 issue carried the results of a study which stated that brain strokes and heart attacks occur more frequently in the mornings than any other times in the day. An older study (June 2009) carried in the journal, Medicine and Science in Sports and Exercise, concludes that exercising post-waking adds greater shear stress on the blood vessels in the body. Thus began the speculation that exercising in the morning might endanger one’s heart.

Earlier studies have already concluded that the risk-rate for cardiac problems is the same while exercising, irrespective of the time of the day. However, recent studies have shown that in individuals who are already suffering from heart disease, the chances of suffering a cardiac arrest or a brain stroke are significantly greater if they exercise in the morning.

Regularity of exercise

Experts stress on the regularity of exercise more than the intensity of exercise. Sustained exercising which is built up gradually is far more advantageous than intense bursts of exercise. Such bursts can strain the heart and therefore, when one starts to exercise, it should be light with a gradual increase. And if one is not exercising at all, it is better to start off.

Conclusion:

Though there are studies to show greater susceptibility to cardiac problems during morning exercise, they are all based on many conditions. The foremost among them is that the person should not be already suffering from a heart disease. The other points to be kept in mind include exercising after taking a light snack and sufficient water, exercising regularly and increasing the exercises gradually.
