Keep Hydrated: Why Drinking Enough Water Helps Support Memory After 55

When we think about looking after our brains, drinking water isn't usually the first thing that comes to mind.

Yet even mild dehydration can affect concentration, memory and mental performance.

As we get older, our sense of thirst naturally becomes less reliable. This means many adults over 55 may not realise they're becoming dehydrated until symptoms appear.

The brain is made up of around 75% water, so it's hardly surprising that hydration plays an important role in keeping it functioning efficiently.

Even losing a small amount of body water can lead to tiredness, headaches, confusion and difficulty concentrating.

Staying hydrated helps your blood circulate oxygen and nutrients to the brain while supporting normal communication between brain cells.

Water is the best choice for most people, although tea, coffee, milk and sugar-free drinks also contribute to your daily fluid intake.

Many people find it easier to drink enough by carrying a reusable water bottle or keeping a glass of water nearby throughout the day.

Eating water-rich foods such as cucumber, tomatoes, oranges, strawberries and melon can also help.

If you're exercising or the weather is particularly warm, you'll usually need to drink more than usual.

Be aware that some medications may also affect hydration, so speak with your GP or pharmacist if you're unsure.

Making hydration a habit doesn't require dramatic changes—simply sipping water regularly throughout the day can help support clearer thinking, better concentration and healthier brain function.

Looking after your memory isn't always about doing something complicated. Sometimes it's as simple as reaching for a glass of water.
