A new survey-based study shows that sleeping longer one night is linked to an increase in sexual desire the following day for women, linking sleep and sex.

Based on the results published in the Journal of Sexual Medicine, the women reported masturbating on an average of one to two days during the 14-day survey period and engaging in partnered sex an average of three to four days.

They slept for an average of seven hours and 22 minutes per night.

Sexual desire was higher for women taking oral contraceptives and dipped during menstruation, the authors found.

When all these factors were accounted for, longer sleep duration predicted higher sexual desire the following day.
