Therefore, it’s vital that we stay hydrated. The factors affecting hydration are: ### Environment ![Environment](https://image-v2.cdn.app.senecalearning.com/2018-03/65b7c97a-986b-4520-b413-4ad469715036/shutterstock_95661016.jpg) - Depending on where we are, the amount of water we need can change. - E.g. in a desert we will need to drink more water to help keep us cool. ### Temperature ![Temperature](https://image-v2.cdn.app.senecalearning.com/2018-03/264ab75a-28ce-49ed-ac81-362e6eb0f479/shutterstock_496310446.jpg) - The hotter we are, the more we will sweat and the more water we will lose. We need to drink more water to replace the water lost in sweat. ### Exercise ![Exercise](https://image-v2.cdn.app.senecalearning.com/2018-03/435cf69a-b849-4e56-8ea3-40c940a430fd/shutterstock_569531539.jpg) - If we exercise, we are more likely to lose water (by sweating), which we will need to replace. ## Dehydration If we do not keep the water balance in our body, we can become dehydrated (lose too much water). Dehydration can lead to: ### Thickening of the blood ![Thickening of the blood](https://image-v2.cdn.app.senecalearning.com/2018-03/ff8e5b1b-e37a-4df7-a262-93f983b73b9d/shutterstock_384385222.jpg) - This means that water is lost from the blood, so the blood becomes thicker. - This reduces blood flow. ### Increased heart rate ![Increased heart rate](https://image-v2.cdn.app.senecalearning.com/2018-03/fd2f5d1b-a51a-4bf4-a820-9dcf08ce0e96/shutterstock_282286424.jpg) - Thicker blood means the heart has to work harder and beat more to maintain the blood supply to the body. - This can cause an irregular heartbeat. ### Longer reaction time ![Longer reaction time](https://image-v2.cdn.app.senecalearning.com/2018-03/7de319c6-0828-40e7-a3c2-194de7ceae76/shutterstock_776992483.jpg) - This means that it takes longer to respond to a stimulus. - Increased reaction time can result in a decrease in performance. ### Fatigue ![Fatigue](https://image-v2.cdn.app.senecalearning.com/2018-03/88731d41-a7ff-405c-91d6-57eafa550c3b/shutterstock_324269153.jpg) - Muscles can cramp and fatigue will happen more quickly because of water loss. - This is because waste products cannot be removed as quickly as usual. ### Increased body temperature ![Increased body temperature](https://image-v2.cdn.app.senecalearning.com/2018-03/f9d7bc13-40e7-470c-a64b-3ac693db3472/shutterstock_1026841336.jpg) - The body can also begin to overheat as there is less water to cool the body down ## Test yourself on Hydration - Which of the following is not a factor affecting hydration? - What % of the human body is water? - What chemical reactions does water help with in the body? - Consequences of dehydration [Practise this topic for free](https://app.senecalearning.com/classroom/course/91c639c0-06b3-11e8-a7fa-d5f998ee5b98/section/14dc9730-2227-11e8-a5db-6d7ab2cb7567/session) -
