Here's The Best Time of Day To Have Sex

What's the key to better sex, weight loss and increased productivity? Timing.

That's according to clinical psychologist Michael Breus and his new book The Power of When.

Breus, who specialises in sleep disorders, believes the problems encountered in these areas of life may not be down to how you're working, exercising or having sex, but simply that you're doing these things at the wrong time.

"When is the ultimate life hack. It's so much easier than trying to overcome an obstacle or changing the way you do something," he told The New York Post.

The Power of When dissects 75 activities, from drinking coffee to exercising, and tells you the best time to do each of them, depending on your biological clock, or your "chronotype."

Breus has identified four different chronotypes based on people's sleep requirements and personalities. The chronotypes are:

• Dolphin: Intelligent, neurotic, light sleepers.
• Lion: Morning-oriented, driven, optimistic, need a medium amount of sleep
• Wolf: Night-oriented, creative, extroverted, need a medium
amount of sleep
• Bear: is fun-loving, outgoing, like the sunlight, need to sleep a lot.

According to Breus, "There are certain times when our body is burning calories or producing more oestrogen, so it's all about using that knowledge" in order to operate at your optimum.

For seventy per cent of people, the time they have sex is based on convenience. This tends to be when you're already in bed for the night, says Breus.

"But you want to have sex when your testosterone levels are high, and that happens to be earlier in the evening or in the morning."

If your partner has a different chronotype to you, Breus advises finding a time between both your peaks.

• Dolphin: 8pm.
• Lion: 6am to 7am.
• Bear: 7am or 9pm.
• Wolf: 10am or 10:30pm.
