😒 Cognitive ability
Fuels preconceived notions about cognitive ability
We tend to overlook that cognitive abilities are not all or nothing. None of us work at full cognitive capacity 24/7. Countless factors can affect our ability to think and process. And fewer than you may think are caused by a disability or disease like Parkinson's or Alzheimer's.
Cognitive ability declines, for example, when we...
- don't drink enough water. With as little as 1% dehydration, thinking ability declines by 5%.
- live with chronic stress and burnout symptoms.
- age - according to a US study, it starts once we hit age 27.
- have not learned to keep our brain active throughout life
- avoid physical activity
- sleep too little
- take certain medications, even over-the-counter sleeping pills or painkillers like acetaminophen affect cognitive performance.
