Before you blame aging for your brain fog…….
💙check your water intake💙
Your brain is approximately 75 percent water. Studies show that even a ❌2 percent ❌decrease in hydration, a level most people would not even notice as thirst, causes measurable decline in memory, attention, reaction time, and mood.
By the time you feel thirsty, you are already dehydrated enough for your brain to be underperforming.
▶️▶️▶️▶️▶️As we age, our thirst signal weakens. ◀️◀️◀️◀️◀️
Older adults are chronically under-hydrated not because they choose to be but because their body stops asking for water as reliably.
Drink water consistently throughout the day. Do not wait for thirst. Keep a water bottle visible at all times. Refill it as part of your daily routine.
The afternoon slump, the foggy thinking, the short temper. Before you reach for coffee or supplements, drink a glass of water.
