With summers on our head, it is essential that we have at least 2-3 litres of water per day. Best way to go about is to keep a bottle of water near your bed when you sleep. When you wake up, the first thing you should try and do is drink at least half a litre or 500ml of water (it's much easier than what it sounds). This kick starts your digestive system and also allows for a comfortable visit to the loo in the morning. Keep a sipper handy with you. If you are the kind that really skimps on drinking water, set reminders in your mobile for every hour. Every hour, drink at least one glass of water. If you are in a job that causes you to sweat a lot (field work, constant standing in the sun, strenuous work), the body is not only losing fluids, but also losing salts. Add a little ORS or suitable mineral rich supplement to replenish these salts in your body. Interesting tid-bit from History - During the Six-Day war, or Yom Kippur War, Israel had one very simple rule for their soldiers. Every hour, 1 liter of water. They would stand in a circle, finish their canteen of water and then get back to the task at hand. This kept them hydrated, strong and fresh enough to fight the enemy. Egypt by comparison had set only 1-2 liter water for their soldiers for the whole day (24 hours). Eventually the soldiers were weary, de-hydrated and exhausted by the time the Israeli forces attacked. Most of them simply surrendered or died of thirst. #truestory The color of your pee is also an important indication of how hydrated you are, Here's a useful chart - I generally keep a bottle handy and now over several years have formed a habit of drinking every now and then. If you do not like the taste of water (some people don't) much, you can opt for having a) plain soda, b) adding lemon and salts to give it a distinct flavor Avoid fizzy drinks, especially Colas, since they have a) Sugar - which increase thirst (for the body to burn it) or gets converted to fat (if you don't burn it off) b) Caffeine - which acts as a dirutec and forces the body to release water from the system. c) they do nothing to quench your thirst. Control your alcohol intake during Summers. Avoid vodka, rum, whiskey etc. These would de hydrate your body further. If you must, Beer and wine are better alternates to drink, since they have more water than alcohol and it keeps your body in a much better condition. If you must consume hard liquor like rum or vodka, do this; Have a glass of water after every drink that you have. If possible have 2. This will keep you in good shape, and also keep you from consuming too much. Remember, too much water for a sedentary life style can also be harmful, since it can cause dilution of fluids and salts in the body. So strike a balance and drink right. Ensure that you spread the word also.
