I asked my Doctor why people need to urinate so much at night time. Answer from my Cardiac Doctor - Gravity holds water in the lower part of your body when you are upright (legs swell). When you lie down and the lower body (legs and etc) seeks level with the kidneys, it is then that the kidneys remove the water because it is easier.

Drinking water at a certain time maximizes its effectiveness on the body

2 glasses of water after waking up - helps activate internal organs

1 glass of water 30 minutes before a meal - helps digestion

1 glass of water before taking a bath - helps lower blood pressure

1 glass of water before going to bed - avoids stroke or heart attack

If you take an aspirin or a baby aspirin once a day, take it at night. The reason: Aspirin has a 24-hour "half-life"; therefore, if most heart attacks happen in the wee hours of the morning, the Aspirin would be strongest in your system.

There are other symptoms of a heart attack, besides the pain on the left arm. One must also be aware of an intense pain on the chin, as well as nausea and lots of sweating; however, these symptoms may also occur less frequently.
Note: There may be NO pain in the chest during a heart attack.
