IMPROVE ON SLEEP

Good health needs a good sleep. Going to bed before you’re tired. Not eating or reading in bed. Go to bed at the same time before midnight and get up at the same time. Your body likes routine (常规) for a good night’s sleep.

STAY FREE OF FLU

ORAL (口腔) HEALTH

Brush your teeth twice daily and visit the dentist at least once a year. The mouth is a mirror (镜子)of disease(疾病). The oral examination (检查)is not only for the health of teeth, but the whole body. For more of it, please visit www. mydr. com. au.
