I’ve read that one reason heart attacks might happen in the early hours of the morning is dehydration especially from mouth breathing and snoring which breathes out water rather than retaining it in the sinuses.
Keeping the heart hydrated night and day when we exercise when we sleep when it’s hot when it’s cool.
A glass of water by our bed might save our life if we wake in the night thirsty.
Drink water firsr second third. So easy.
Do I need a drink of water? Have a drink now.
Keep a container of water by the TV by the computer by the bed.
Take several litres of water in the car.
