Novak Djokovic opened up about a lingering health problem that has been affecting his performance, after his unexpected loss in the second round of the Cincinnati Open. The 39‑year‑old Serbian star explained that the combination of high temperatures and heavy humidity in Ohio aggravated his condition, which became evident during his 6‑2, 4‑6, 4‑6 defeat to Argentina’s world No. 50, Thiago Agustín Tirante. This match marked Djokovic’s first competitive appearance since his semi‑final exit at Wimbledon in July, where he fell to Jannik Sinner.

Early in the Cincinnati contest, the Serbian champion appeared to be fighting an uphill battle. Midway through the second set, he dropped to his hands and knees and requested a medical timeout, a visual cue that something was seriously amiss beyond the usual fatigue that accompanies a three‑set battle. Speaking to the press after the match, Djokovic offered a candid assessment. "Congratulations to my opponent.

It definitely wasn’t an enjoyable match for me. The way I felt… it’s not the first time, and I suspect it won’t be the last, but that’s the reality," he said.

He went on to describe the underlying issue as a chronic health condition that has been bothering him for the past few years. "It’s a condition I’ve been dealing with health‑wise for a couple of years now. It creates a lot of problems, especially when the weather is hot and humid," he explained. Djokovic admitted that he had anticipated the possibility of the ailment flaring up under adverse conditions, but added that the mental pressure of competition – the nerves, the expectations, and the intensity of a high‑stakes match – can exacerbate the symptoms.

"I did expect it could happen, but there are all these factors, like nerves and everything involved, that make it worse, and that’s exactly what occurred today," he reflected. The Serbian’s remarks shed light on an aspect of elite tennis that is often invisible to fans: the way environmental factors can magnify underlying medical issues. Heat and humidity are known to strain the cardiovascular and respiratory systems, and for athletes with pre‑existing conditions, the impact can be pronounced. In Djokovic’s case, the condition appears to affect his stamina and perhaps his ability to recover quickly between points, leading to a noticeable dip in performance when the temperature rises.

Despite the disappointment, Djokovic remained optimistic about his future. When asked whether he would return to Cincinnati next year, the three‑time champion of the event responded, "I certainly hope so, but it looks more likely not, unfortunately. But let’s see what the future brings." His answer reflects both a desire to compete at the highest level and a realistic assessment of the challenges his health may present.

The loss also serves as a reminder of the depth of talent on the ATP Tour. Tirante, ranked 50th in the world, seized the opportunity to showcase his skill and composure, capitalizing on Djokovic’s vulnerability.

For the Argentine, the victory is a career‑defining moment, while for Djokovic it underscores the importance of managing health alongside the relentless demands of the tour. Looking ahead, Djokovic’s situation will be closely monitored by his team, medical staff, and fans alike. The Serbian legend has a history of overcoming injuries and setbacks, from his early‑career knee problems to more recent back issues. His ability to adapt his training, recovery protocols, and match preparation will be crucial if he hopes to remain competitive in the latter stages of his career, especially as he approaches his mid‑40s.

The broader tennis community can also take note of the conversation around player health and environmental conditions. Organizers of major tournaments are increasingly aware of the need for adequate cooling measures, heat policies, and medical support to safeguard athletes. As climate patterns shift and extreme weather becomes more common, the sport may see more instances where players have to contend with health challenges amplified by the elements. In the meantime, fans can continue to follow Djokovic’s journey through the ATP and WTA tours, which are broadcast live on Sky Sports.

The network also provides coverage of the US Open, beginning on August 30, and offers streaming options through NOW for those who prefer to watch without a contract. As the season progresses, the tennis world will watch to see how Djokovic manages his condition, whether he can return to Cincinnati, and how he adapts his game to stay at the top of a sport that demands both physical resilience and mental fortitude.
