BEST TIME FOR A FLU JAB — AND TO MAKE DECISIONS

IF YOU have an important decision to make, do it between 10am and 3pm when you have optimal brain function. At around 9pm or 10pm the alertness drive actually reverses.

TAKE anti-inflammatory drugs at night: the inflammation that causes rheumatoid arthritis increases after midnight, so taking your pills at this time will pre-emptively reduce the severity when you wake up.

GET a flu shot in the morning and make sure you’ve had a week’s worth of good sleep beforehand.

Preliminary studies have shown morning jabs give better protection.
