Does the circadian rhythm, our “ body clock “, influence our libido?

According to Dr. Paul Kelley, a clinical research associate at Oxford University's Sleep and Circadian Neuroscience Institute, it does. The circadian rhythms are the changes in our body in relation to sunlight. They control every system and every cell in our body. And they change with age. It’s all about balancing the cocktail of hormones and neurotransmitters.

Dr. Kelley did some research about the best time to wake up and have sex according to peoples age. These were his findings:

Although people in their twenties feel like having sex all the time, they should set their clock at 15:00h because then their body experiences a spike in energy. He advises waking up at 9:30h ( when orexin, the hormone that wakes you up, overrides melatonin, the hormone that makes you sleep ) and going to sleep at 01:00h.


8:20h is the perfect time to make love because the sunlight boosts testosterone in men and women by stimulating the hypothalamus ( hormone regulating organ in the brain ). People in their thirties should wake up around 8:10h and go to bed around 23:40h. Young parents are advised a power nap around 15:40h. 


The best time for sex changes to 22:20 for people in their forties because the release of oxytocin, the “love” hormone, helps them rest better during the night. They shoud try to go to bed before midnight and get up around 7:50 h.

Does the circadian rhythm influence our libido?


They should get it on a little earlier, around 22:00 h, and go to sleep soon afterwards, around 22:30 h. From this age on the liver function slows down so be carefull with drinking alcohol before bedtime .

Sixties - Seventies

The best time to enjoy some love making is around 20:00 h. The release of oxytocin will help to relax before an early bedtime, around 22:00 h. The best time to get up in the morning is around 6:30 h, to enjoy an early breakfast. 

These scientific guidelines are well worth trying, but of course making love is also about spontaneity and doing it whenever you feel like it. 

As the Scottish say: no rules, great sex! ;) 

Cease the day and have fun!
