Exercise and Coffee Together May Help Prevent Skin Cancer

If you’re already working out to stay healthy, adding a cup of coffee at the right time might do more than boost your performance. A surprising study suggests that drinking coffee before or after exercise could also lower your risk of skin cancer—especially the kind caused by sun exposure.

Yes, according to research presented at the American Association for Cancer Research annual meeting in Chicago, drinking coffee around the time of exercise reduced skin tumors in mice by up to 62% and shrank existing tumors by up to 85%.

What the Study Found in Mice

Researchers at Rutgers University’s Ernest Mario School of Pharmacy conducted experiments on mice exposed to UV radiation, a key cause of skin cancer. They tested several groups: mice that only exercised, mice that only consumed caffeine, mice that did both, and a control group that did neither.

The most significant results came from the “caffeine + exercise” group. These mice showed:

• 62% fewer skin tumors compared to untreated mice
• 85% smaller tumors overall
• 63% less weight gain when fed a high-fat diet

Even on their own, both caffeine and exercise had measurable benefits:

• Caffeine alone reduced tumors by 27% and shrank them by 61%
• Exercise alone reduced tumors by 35% and shrank them by 70%

How Caffeine and Exercise Work Together

According to lead researcher Dr. Yaoping Lu, the combination of physical activity and caffeine appears to dramatically lower bodily inflammation—a key factor in cancer development.

In fact, the combined treatment reduced markers of inflammation by a remarkable 92%. This anti-inflammatory effect is believed to be the main reason behind the dramatic drop in both tumor number and size.

“This therapy not only improved tumor outcomes,” said Dr. Lu, “but also helped counteract weight gain associated with high-fat diets, suggesting broader metabolic benefits.”

What This Means for Humans

While the study was conducted on mice, researchers believe the mechanisms—particularly the anti-inflammatory impact of caffeine and exercise together—are likely to apply to humans as well.

The exact dose of caffeine used in the study isn’t specified for human translation, but the findings support the idea that a moderate coffee habit combined with regular workouts could offer protective effects against UV-triggered skin cancers.

Dr. Lu and his team suggest that the synergy between caffeine’s biochemical effects and exercise-induced metabolic changes creates a more cancer-resistant environment in the body.

Frequently Asked Questions

How much coffee should I drink before or after exercise to get these benefits?

The study didn’t specify a human-equivalent coffee dosage, but it evaluated the effects of caffeine alongside exercise. For humans, a typical cup of coffee contains around 80–100mg of caffeine, and moderate intake is generally considered safe and potentially beneficial when paired with regular physical activity.

Does decaf coffee have the same anti-cancer effect when combined with exercise?

No, the study focused on caffeinated coffee. The anti-cancer benefits were attributed to caffeine specifically, which was shown to work in tandem with exercise to reduce inflammation and tumor growth. Decaf would not provide the same caffeine-related effects.

What types of skin cancer are affected by this coffee-and-exercise combination?

The study looked at UV-induced skin cancers, particularly those related to sun exposure. While the research was done on mice, the findings suggest potential protection against common sunlight-triggered skin cancers like basal cell carcinoma and squamous cell carcinoma, with possible relevance to melanoma as well.

Can I get these anti-cancer benefits from other sources of caffeine?

The study used caffeine in the form found in coffee. While other caffeine sources (like tea or energy drinks) contain similar compounds, coffee was the delivery method tested. The broader anti-inflammatory and metabolic impacts of exercise combined with caffeine are likely the key, but coffee was specifically tied to the tumor reductions observed.

How soon before or after exercise should I drink coffee for best results?

The exact timing wasn’t defined in this study. However, for optimal metabolic and anti-inflammatory effects, having coffee shortly before or immediately after your workout may help align caffeine’s stimulatory and anti-inflammatory impacts with the body’s post-exercise state.
