Summary
Story at-a-glance
- Spending more than two hours a day watching TV increases your heart disease risk by 12%, even if you have low genetic risk for Type 2 diabetes
- Limiting television viewing to less than one hour daily cuts heart disease risk, even in people with high genetic risk for Type 2 diabetes, according to new research
- Each extra hour of daily TV time raises your chances of developing heart disease by 3%, building up dangerous plaque in your arteries over time
- Watching TV displaces physical activity, encourages junk food and alcohol consumption, and leads to sluggish blood flow and dangerous clot formation
- Reducing your TV time and moving more helps prevent heart disease, no matter your genetics — sitting less is a simple, powerful daily change

| 0:14.2 | Hello and welcome to Dr. Mercola's Cellular Wisdom. I'm Ethan Foster, your host, and I'm here today to delve into an |
| 0:22.0 | important health topic. We're going to explore how limiting television viewing time can |
| 0:26.7 | significantly reduce heart disease risk. Joining me is Ilara Sky, who provides clear insights |
| 0:32.9 | on natural health approaches. Ilar, thank you for being here. Thank you, Ethan. I'm looking forward to discussing |
| 0:39.5 | this research. We have new evidence showing that spending too much time watching TV can raise the |
| 0:44.9 | risk of heart disease. It appears the risk increases, even if you have a low genetic predisposition |
| 0:50.1 | to type 2 diabetes. So this information is relevant to a very broad audience. |
| 0:55.0 | To give everyone a quick overview, a study recently published in the Journal of the American |
| 0:59.6 | Heart Association found that people who watch more than two hours of TV a day have a 12% |
| 1:05.6 | greater risk of developing heart disease, regardless of their genetic background. |
| 1:10.0 | What's even more interesting is that |
| 1:12.0 | keeping viewing time under an hour daily appears to reduce that risk substantially, even in |
| 1:17.5 | individuals with a higher genetic risk for type 2 diabetes. Correct. In that particular study, |
| 1:23.9 | researchers analyzed data from over 300,000 participants in the UK Biobank. They followed these |
| 1:30.2 | individuals for nearly 14 years. None of the participants had heart disease or type 2 diabetes |
| 1:36.2 | at the start. Researchers then calculated each participant's genetic risk by checking 138 genetic |
| 1:43.2 | variants linked to type 2 diabetes. |
| 1:46.1 | They wanted to see whether those with a predisposition to diabetes would also be more susceptible |
| 1:51.1 | to atherosclerotic cardiovascular disease if they spent hours in front of the TV. |
