Lesson details
Key learning points
- Dehydration occurs when there is an excessive loss of water which interupts body functions.
- Maintaining hydration helps prevent dehydration and its consequences.
- Dehydration thickens the blood, which slows blood flow.
- Dehydration leads to increased heart rate, overheating, slower reaction times and muscle cramps.
Keywords

Dehydration - excessive loss of body water interrupting the function of the body
Reaction time - the time taken to initiate a response to a stimulus

Common misconception
The main consequences of dehydration are headaches and dizziness.
Headaches and dizziness are likely effects of dehydration, however the GCSE specification expects students to be able to understand the physiological reasons behind these such as slow blood flow, increased heart rate and body temperature.
