Clue to morning heart-attack risk

The struggle to get out of bed in the morning may feel like a health hazard, but it is not to blame for the spike in heart attacks and strokes suffered in the early hours.......

If blood would pool in the vessel(venous stasis)when one sleeps, fluid would seep out of it causing oedema. Although this is the case in folks with Heart failure whose heart function is compromised.

On the other hand, when one is asleep(body shutdown), the body does its best to conserve all of its resources and energy by regulating vital body functions such as circulation to save energy. This is accomplished by primarily reducing blood pressure and reducing heart rate and force of contraction, since the requirements of the body are lower when one is asleep. The way the body does this is by contraction and expansion of vessels.

When one wakes up in the morning/evening/whenever, the body startsup up, this is a slow process or a fast one, depending on how fit an individual may be. The contracted vessels would now have to expand so that more blood could flow through it, and the heart also increases its rate and its force of contraction. If the person's cardiovascular system is unfit, this sudden accomodation would cause unpleasant symptoms or even serious events such as a stroke , heart attack etc..

Drinking water would probably just make you pee/or not pee. Instead, the trips made to the bathroom could have a benefit, since it involves some physical effort and restarting the system.

Diuretics would help people suffering from congestive heart symptoms by reducing the fluid in the body, hence reducing the load on the heart.

We KNOW viscosity of the blood is related to heart attack risk due to the recent finding of 50% death in those with congestive heart failure who have increased viscosity ..

Therefore the finding of increased viscosity in the morning comes .. into ..
play ..?

OSAS and in 8 healthy controls at 8-9 p.m. and at 7-8 a.m. the morning after.
WBV values were normalized on Hct by the computation of the standardised normal deviate z on the normal database of the laboratory. RESULTS: No changes were observed in controls. Hct, F and normalized WBV (independently from Hct changes) significantly increased in the morning hours in OSAS patients. CONCLUSIONS: Viscosity of whole blood increases in the morning in
OSAS patients but not in healthy controls. This condition may be related to the increased susceptibility to cerebral ischemia in patients affected by
OSAS, particularly evident in the early morning. PMID: 10711818, UI:

Blood pools in the vessels as we sleep as well AND we typically avoid drinking fluids before bed so as not to be interrupted for pee time.
My advice... drink plenty of water at night and when you get up to pee drink some more. Eating shittake mushrooms can help too as they thin the blood in a good way.

I wonder if this might have some implication for weight training as well. My inclination would be to lift in the morning and in the evening. Is this a bad idea?
