Take our challenge and win a Tempur mattress

Feeling sleepy? Try to stay awake for just a little while, because The Times Health Club has a challenge that could make your dreams come true. We know what a common problem lack of sleep can be, so we've gathered together expert advice from Dr Mark Porter, Amanda Ursell and James Duigan to help you snooze with success.

The challenge is: we want you to sleep for 15 years this March. Don't worry, you're not alone: the whole club is invited to join in. To play your part, you just need to get eight hours a night, log your progress on the site and see how the rest of the club is getting on. How restful.

One lucky participant will win a Tempur pressure-relieving mattress and two pillows worth up to £2,000 (click here for terms and conditions). And not only that, but all members can save 10% on Tempur's product range.

If you're already a Times Health Club member, click here to sign up to the challenge. If you're not yet a member, click here to sign up today, absolutely free, and find out all the benefits that being a member can bring. More than 100,000 members know it works.

Good luck, and sleep well!
