Regular sexual intimacy increases telomere length

There’s nothing like the feeling of sharing moments of intimacy with someone you feel close, vulnerable and safe with. Someone you can really connect with. While sex as a purely physical act has its health benefits, when coupled with emotional intimacy and trust, there are further benefits of improved relationship satisfaction and longevity. Aside from that post coital glow that feels absolutely amazing, regular sexual intimacy is associated with greater resting heart variability  (a predictor of health and longevity), reduced daily cortisol levels  (decreased stress), lower daily  somatic symptoms  (physical symptoms associated with stress) and a  stronger immune response. Simply put, regular sex is really, really good for you.

Something else regular sex might be beneficial for? Slowing down the aging process.  Research has found that regular sexual intimacy is associated with longer telomere length. Telomeres, first observed by scientists in the 1930s, protect our DNA and were discovered to be directly linked to cellular aging almost 30 years ago.

What are Telomeres?

Telomeres are caps that are found at the end of each strand of DNA. Their function is to protect our chromosomes from deteriorating during cell division. Throughout our lives, our cells are constantly replenishing themselves by replicating themselves. Each time a cell divides, telomere length decreases.

With time, telomeres become too short which makes them stop functioning like they should. This leads to the aging of cells and ultimately, the aging of our appearance.

Time, however, isn’t the only thing that can shorten telomere length. Telomeres can also be shortened by poor diet, stress, smoking, lack of exercise, and obesity.

Shorter telomere length has also been associated with childhood trauma. The rate of telomere shortening is fastest in infancy and early childhood, and it’s believed the regulation of telomere may be programmed in early childhood development. Physical, sexual, emotional, and mental abuse, as well as physical and emotional neglect are all believed to be precursors to stress which leads to cellular aging. Those who experience psychological stress have higher levels of oxidative stress which has shown to shorten telomere length  in vitro.  

Shorter telomere length is directly linked  to premature aging, as well as the onset of age-related diseases. While telomere length naturally shortens as people age, lifestyle habits (an unhealthy diet, lack of exercise, obesity, smoking) can increase the rate in which telomeres shorten. Studies have shown that people with shorter telomere lengths are at a higher risk for developing several different types of cancer  and  premature heart disease.  

The shortening of telomere length is a huge aspect of aging on a cellular level, with the length of telomeres representative of a person’s biological age rather than their chronological age. Have you ever been taken completely off guard when someone tells you that they’re actually 10 years older than you thought they were? This is because their biological age is much different than their chronological age. These are often the people with the poor lifestyle habits that are known to lead to shorter telomeres.

The biological age of a person represents how old they appear or feel, where chronological age is the actual years they’ve been alive. This is why some people might seem to be in their 60s, but chronologically they’re really only 45. And vice versa. Someone who’s chronological age is 50 may seem much younger and have a biological age of 35.

Does Sexual Intimacy Really Increase Telomere Length?

In March 2017, scientists in California published a preliminary study  that found women who are having sex at least once a week with their partner have considerably longer telomere lengths.

According to the study’s lead researcher, Tomas Cabeza de Baca of the University of California San Francisco, “Past research has found that high quality, satisfactory relationships and sexual intimacy are good for physical and mental health. Based on this body of research, we wanted to explore whether there was a health-enhancing relationship between sexual intimacy, telomere length, a biological index of systemic aging and health, and telomerase, an enzyme produced by cells to lengthen telomeres. We also examined whether there was an association between relationship satisfaction, positive/negative partner interactions and our two measures of health (telomere length and telomerase activity).”

The study, which consisted of 129 women who were partnered with children, discovered that regular sexual intimacy was positively linked to two measures of telomere length. Researchers found that out of the three measures of telomere length, two measurements were significantly increased: whole blood telomere length and Peripheral Blood Mononuclear Cell (PBMC) telomere length.

According to Baca, “Women who reported being sexually active during the week had significantly longer telomere length across whole blood and PBMC than women who were not sexually active.”

Here’s something else. Researchers of the study found that increased telomere length in women having regular sex had nothing to do with whether they were happy in their relationship or not. They measured relationship quality, perceived stress in the relationship, and everyday support or conflict. Regardless of the quality of their relationship, regular sex during the week was still associate with longer telomere length.

Although the study was simply observational, researchers are hopeful that further investigation of telomere length and sexual intimacy will determine once and for all if having regular sex can keep you looking young.

Longer Telomeres: A Drop in the Fountain of Youth

Though the research is clear that regular sexual intimacy protects health and may increase longevity, there are times in our lives where we might not be sexually active either by choice or because of illness or disability. If you’re not having regular sex, the following are all ways to naturally increase telomere length, so you too can harness that youthful glow:

  • Get Regular Exercise: A  2015 study  found that individuals engaged in regular physical activity had longer telomere length. Walking, cycling, strength training, and high-intensive physical activity all showed to increase telomere length.  
  • Eat Antioxidant-Rich Foods:  It’s believed that foods that are high in antioxidants can protect cells and telomeres from further damage. Omega-3s (found in flax, fish oil supplements, soy, and green leafy vegetables), berries (acai, elderberries, blueberries, and cranberries contain highest levels of antioxidants), grapes (contain resveratrol, which gives DNA time to repair free radical damage), citrus fruits, sweet potatoes, and green tea are all foods that provide a powerful punch of antioxidants.  
  • Take a Multivitamin: A  2009 study  found that multivitamin use is associated with longer telomere length in women.
  • Get Your Yoga On:  In a 2014 study,  breast cancer survivors who practiced mindful meditation and gentle yoga kept their telomere length, while those who did not practice mindfulness or yoga had decreased telomere length during the time period of the study.
  • Find Ways to Reduce Stress: There have been numerous  studies that correlate chronic stress and shorter telomere length. Reducing stress can directly counter the accelerated shortening of telomeres. While the connection to the mind and cells remains a mystery, researchers believe that psychological stress can affect the aging of cells through three different pathways. These include: oxidative stress, immune cell function or distribution, and telomerase activity.
