Processing emotions
Dreaming might help our brains process feelings and emotions from our everyday lives.
Organising memories
Dreaming might help our brains organise and store memories, including things we’ve experienced.
Processing information
Dreaming might help our brains work through information we’ve learnt or experienced during the day.
How do memories form?
Experiences are converted into electrical signals.
These signals travel through networks of brain cells called neurons.
Repeated communication between neurons strengthens their connections.
This process is called long-term potentiation (LTP).
It helps memories become stronger and last longer.
What can affect our memory?
Ageing can cause natural changes in the brain.
Chronic stress can affect memory.
Depression can make it harder to concentrate and learn new information.
Social isolation can also affect our ability to process and remember information.
How can we help maintain our memory?
Regular physical activity.
Eating a balanced diet.
Challenging our brains with new activities.
Learning new languages and skills.
