How a poor night's sleep can affect your brain
Sunday, 13 September · 1 min read

Sleep is crucial for good health and wellbeing and a poor night's sleep can have a noticeable affect on this — and how your brain functions.

It can:

  • make you forget things more easily
  • make you short-tempered
  • make it harder to focus or concentrate
  • slow your reaction speed
  • increase the number of mistakes you make

Good quality sleep improves your memory by boosting connections between cells in the brain and allowing information to flow more easily from 1 part of the brain to another.

Some research also suggests you’re more likely to remember information you’ve learned if you sleep well afterwards.

But poor sleep — particularly over many days or weeks — can have the affects listed above, but also make you feel down and more prone to certain medical conditions. This includes obesity, heart disease, high blood pressure and diabetes.

Most adults need 7 to 9 hours of quality sleep each night to function well the next day and in the long term.

If you’re tired from 1 night — or more — of bad sleep, try our tips below and make changes to improve your sleep.
