If you regularly sleep less than six hours a night, you are four times more likely to catch a cold than someone who sleeps longer. But you're not alone. Around 30 percent of the population suffer from sleep problems of some type, which can affect everything from your mood and hormones, to your immunity and recovery time. This week we meet a psychiatrist and sleep expert who reveals the key to developing better sleep habits.

Listen and learn:

• How fewer than six hours of sleep increases your likelihood of getting sick
• How circadian rhythm and the homeostatic sleep drive affect your sleep
• The effects of alcohol and cannabis on sleep
• The common misuse of melatonin
