Heart attack symptoms vary. Not all people who have heart attacks have the same symptoms or have the same severity of symptoms. Some people have mild pain; others have more severe pain. Some people have no symptoms, while for others, the first sign may be sudden cardiac arrest.
The Institute of Medicine recommends that pregnant women drink 10 cups (2.4 liters) of water each day. Itâs smart to get in the habit now, because if you decide to breast-feed, that requirement increases to 12.5 cups (3 liters) each day.
You may need to drink more water if you: 1  are exercising. 2  are in a hot or humid climate. 3  have a health condition such as a kidney stone (but note that some conditions such as being on dialysis mean that you have to drink less water)  are 1  pregnant. are breast-feeding.
