Life moves in unpredictable rhythms, and so does intimacy. There are times when passion flows freely — and other times when weeks or months slip by without so much as a kiss. But what might seem like just a dry spell could actually be affecting more than your mood. Experts now suggest that extended periods without sex might not only be frustrating, but also harmful to your health — both physically and emotionally.

Recent findings from NapLab show that the average American has sex about once a week. But that number might not tell the whole story. For many people, sexual activity is much more infrequent — and according to medical experts, that absence can ripple into other parts of life in ways most wouldn’t expect.

While some might roll their eyes at the idea that bedroom habits influence well-being, studies increasingly suggest otherwise. Research indicates that celibate individuals are more prone to emotional struggles such as anxiety, mood swings, and even depression. One striking study from Scotland found that people who hadn’t had sex in over two weeks responded more poorly to stress-inducing tasks like public speaking, compared to those who were recently intimate. The reason? It may come down to hormones and the brain’s natural coping mechanisms.

Dr. Sham Singh, a psychiatrist and sexual health expert, explains, “Suppressing sexual urges without finding other stress-relieving outlets can cause a buildup of frustration, which may trigger irritability or increased anxiety.” It’s not just emotional, either. Dr. Singh notes that people who go without intimacy may suffer from physical effects too — like tension in the body, trouble focusing, difficulty sleeping, and even reduced energy levels. These symptoms are linked to shifts in critical hormones, including testosterone, estrogen, and cortisol, the stress hormone.

And while fewer sexual encounters might limit exposure to infections, there’s a trade-off. Researchers at Wilkes University in Pennsylvania discovered that people who had sex at least once or twice a week had 30% higher levels of immunoglobulin A — an antibody that plays a key role in defending against viruses. In short, sex might actually help strengthen your immune system.

The broader impact of abstinence became even more visible during the COVID-19 lockdowns. In 2021, a large-scale study involving 4,000 people found that those who maintained active sex lives during the pandemic reported significantly lower levels of anxiety compared to those who remained abstinent. This may be linked to the surge of endorphins and oxytocin — brain chemicals known for reducing pain and fostering emotional connection — that are released during intimacy.

And yet, despite these benefits, fewer people — especially younger generations — are engaging in sex. Government research shows that Americans between the ages of 22 and 34 are leading the trend toward sexlessness. Among this group, around 10% of men and 7% of women have never had sex, a figure that has roughly doubled for men and increased by 50% for women over the past decade, according to the Institute for Family Studies.

This cultural shift is compounded by broader lifestyle patterns. A Pew Research report noted that about a quarter of Americans under 40 have never been married. Many live alone. With delayed partnerships, busier lives, and increasing reliance on digital social interaction, opportunities for physical intimacy may be shrinking — and the mental and physical consequences are starting to show.

While it’s important to acknowledge that everyone’s needs and experiences vary, these findings make one thing clear: a long stretch without physical closeness isn’t just about missing out on romance. It can change how your body fights illness, how your brain handles stress, and how you feel day to day. Whether partnered or solo, finding healthy ways to connect — emotionally and physically — remains a crucial part of holistic health.
