Our body is losing water through sweating, urinatig and defecating. We lose about 2 to 3 litre water per day in a normal climate. Heat exposure or intense activity will increase the water output. Anway, it’s essential that you replace this water.
Here are some dangerous things that could happen to you if you don’t intake water.
- at 5% of water loss you became thirsty, irritable and weak
- at 10% you will have headaches, will be unable to walk and there will be some tingling sensations in your limbs
- at 15% your vision will be blurred, you will urinate painfully and have a swallen tounge.
- over 15% water loss will result in death.
That’s why it’s very important that you prevent dehydration. You can last at least for a week with only 0.5 Litre of water per day if you stay inactive and cover yourself from the sun or freezing temperatures. But when there isn’t an emergency situation, the regular water intake should be 2 to 3 litre per day.
