It is certainly an invigorating way to start the day and shake off sleepiness.
And morning sex may also be more satisfying than sex at any other time of day, based on new UK research.
It is worth setting the alarm clock, as the most exciting time for passion is apparently 7.30am.
The findings come from 500 men and 500 women, mostly in long-term relationships, aged 18 to 65, who were asked to record the times at which they had sex over six weeks.
On each occasion, they rated their enjoyment of the act out of 10.
Results showed that around 30 minutes after waking up, which was 7am, on average, was the preferred time (stock image)
The most satisfying time for having sex, chosen by almost one in four people, was 7.30am.
Overall, two-thirds of people chose morning sex as the most satisfying, between 7am and 10.30am.
Just 33 per cent said they had the best sex at night, with 16 per cent choosing the best time as 9pm, 15 per cent preferring 10pm and only two per cent saying 11pm.
The findings, from CBD brand Naturecan, follow evidence suggesting men, who are more likely to be night owls, tend to prefer morning sex.
Because having sex releases endorphins, it has been suggested to be one way to start the day in a good mood.
The second most satisfying time to have sex, according to the new survey, is 8am, which is before most people working from home get up to start their day.
For parents with children at home, it can also be a good time slot at the weekend.
The survey also found most people rated 7.45am as the optimal time for breakfast, 12.45pm as the best time for lunch, and 6.15pm as the best time for dinner.
Most people concentrated best at 10am, and became peckish for a snack at 3.30pm.
‘Wine o’clock’, when people had their first drink, came at 6pm for 27 per cent of people, and 6.30pm for 19 per cent, with only 11 per cent waiting until 8pm.
The most popular bedtime was 10pm, with 7am the most popular time to wake up.
For those clearly not having sex on that particular morning, almost one in five picked 7.15am as the best time to go for a run.
On the best time for lovemaking, previous studies have suggested women prefer evening sex, and that it is females who tend to get to choose when a couple will have sex.
Last year, a study led by Tenon Hospital in France found couples may find it harder to conceive if one person is a night owl and the other a morning person.
Experts suspect it is because night owls who go to bed late and get up late would prefer to have lazy morning sex.
If their partner is a morning person, who prefers to get up and get on with things, they typically prefer sex at night.
That means fewer times when both people are in the mood – so less chance of conceiving a child.
The study of almost 200 men and women struggling to conceive, and 171 who conceived a child naturally within a year, identified a clear link with people’s sleep preferences.
Among couples having problems getting pregnant, 37 per cent consisted of a mismatched night owl and morning person.
