The report was written by the Global Council on Brain Health report - a panel of experts convened by Age UK and the American Association of Retired Persons.
As we age, our sleep patterns change, so we become more vulnerable to waking during the night and earlier in the morning.
This is important because, in the long term, poor sleep increases the risk of heart disease, obesity and diabetes, say the report authors.
James Goodwin from Age UK said: "Sleeping is something we all tend to take for granted, but we really have to wise up to the fact that getting the right amount of good sleep is crucial as we age, helping to protect us from all kinds of problems that can affect our brains as well as our bodies.
"The message is that in order to stay mentally sharp in later life - something we all care passionately about - take care of your sleep."
For those struggling with their sleep, the report says:
- If you have trouble sleeping at night, but doze off in the evening in front of the TV, trying going to bed a bit earlier or get off the sofa and walk around for a bit to keep alert
- If you go to bed but can`t nod off, get up for a while and find another quiet place to relax until you feel sleepy enough to try going back to bed
- If you worry a lot while in bed, schedule about 15 minutes each morning as your "worry time" rather than becoming stressed at night
- It is worth chatting to your doctor if you have poor sleep and it is having a negative impact on your life.
