The sound of an alarm clock in the morning could be the most unwelcomed sound - unless it's your sexy wake up call for early morning sex.

While time can be the biggest issue in your morning routine - getting ready for work and getting to work as fast as possible - several minutes of morning sex can keep you looking and feeling young, healthy and elevated all day long. According to the Kinsey Institute for Research in Sex, Gender, and Reproduction, 18 to 29 year olds have sex an average of 112 times per year, 30-39 year olds an average of 86 times per year, and 40-49 year olds an average of 69 times per year. 58 percent of sexual encounters take place in the evening from 11 p.m. to 1 a.m. on Saturdays and Sundays while a smaller percentage takes place at 6 a.m. on Monday morning says a paper published in the Journals of Circadian Rhythms.

Whether it is convenience or instinct to engage in sexual activity towards the evening hours, morning sex is seen as "the hottest time of the day to have sex says Glen Rowan, sexologist to Sowetan Live in South Africa. "NPT [nocturnal penile tumescence] is more commonly referred to as 'morning wood' or 'morning glory'. Whatever you call it, waking up with an erection is as good a reason as any to initiate a little early action" said Rowan.

"Early morning sex kickstarts your day off with you both on the same page. Often, one spouse wakes up on the wrong side of the bed and is grumpy while the other is cheerful. This makes it challenging to emotionally connect. Physically (sexually) connecting puts you immediately into an emotional connection," said Dr. Fran Walfish, child and family psychotherapist and author in Beverly Hills, Calif., to Medical Daily. For couples that have kids, Dr. Walfish suggests the morning to be the perfect time for no interruptions. "Children are in their deepest phase of sleep in the early morning hours and will not accidentally pop in," she said.  

Morning breath, body odor and drowsiness may not be aphrodisiacs to get you and your partner in the mood, but recent research suggests that the pros of morning sex outweigh the cons. Adults who begin their day with sex are said to be healthier and happier than those who have a cup of Joe and some breakfast before starting their day says The Daily Mail.

It's to kick your morning coffee habit to the curb and opt for a natural pick-me-up - early morning sex. Find out how sex in the a.m. can give you mind and body the boost you need to start your day while you stay young and healthy.

Improves Immunity

The production of Immunoglobulin A (IgA) -an antibody that protects against infection - is increased during morning sex. During sexual activity, the production the IgA antibody takes place in mucosal linings of the female genital tract that provides a barrier to prevent transmission of infectious diseases. In a study conducted at Wilkes University in Wilkes-Barre, PA, researchers found that having sex once or twice a week boosts the immune system. Those that had frequent sex had a 30 percent IgA increase compared to their non-sexual counterparts. Frequent morning sex can keep antibodies levels high to provide your body protection from foreign invaders in your body.

Improves Mood

Morning sex can improve your mood because of the serotonin levels released during sexual activity. Sex is a natural way to boost your mood with an orgasm releasing more serotonin to your brain. In a study published in the journal Fertility and Sterility, researchers found that taking various serotonin reuptake inhibitor antidepressants (SSRIs), can cause sexual dysfunction in men and damage their sperm.

Improve A Man's Sperm Quality And A Woman's Fertility

Frequent morning sex can improve sperm quality and even improve fertility in a woman. In a study conducted at the Sydney IVF Clinic in Wollongong, AU, researchers studied 118 men who had higher than normal DNA sperm damage accessed by the DNA Fragmentation Index (DFI). The Australian scientists instructed the men to ejaculate daily for a week to lessen their DNA sperm damage. The results of the study showed that 96 of men experienced a 12 percent decrease in sperm damage. The less DNA damage a sperm has the more likely a woman's fertility increases.

Improves Tone And Texture Of Your Skin And Hair

An orgasm during morning sex releases chemicals that can increase estrogen levels in the body and improve the tone and texture of your skin, and even hair. Blood circulation flow is improved during sex which helps get oxygen to the skin and provide a natural, eliminating glow to your face says UWire University of Wisconsin Madison.

Reduces The Risk Cardiovascular Disease

The act of having morning sex multiple times a week can reduce the risk of having a heart attack or stroke by half. In a study conducted at Queens University in Belfast, researchers followed 1,000 middle-aged men over a period of 10 years. Researchers in Belfast compared the participants of their study to the participants of a study published in the British Medical Journal to study how having an orgasm can affect a man's health. As a follow-up, researchers focused on the cardiovascular health of the men and found that a man can reduce his risk of cardiovascular disease by half if he has sex two to three times a week.
