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.
The NHS has detailed how much water we should be drinking on their website: The European Food Safety Authority recommends that women should drink about 1.6 litres of fluid and men should drink about 2.0 litres of fluid per day. That's about eight glasses of 200ml each for a woman, and 10 glasses of 200ml each for a man.
