A preventative cardiologist has detailed six specific habits he strictly avoids after 6pm to safeguard his heart, urging the public to adopt similar practices to enhance cardiovascular wellbeing and mitigate long-term health risks.
The Critical Evening Window for Heart Protection
Dr Francesco Lo Monaco, founder of The National Heart Clinic on London's Harley Street and author of "Heart Saviour," emphasises that evening routines profoundly influence heart function. With cardiovascular diseases affecting approximately 8 million individuals in the UK, according to the British Heart Foundation, and over half the population projected to develop such conditions in their lifetime, proactive evening habits are essential for prevention.
1. Eliminate Strong Antibacterial Mouthwash
Dr Lo Monaco strongly advises against using potent antibacterial mouthwashes in the evening. He explains that oral bacteria play a crucial role in converting dietary compounds into nitric oxide, a molecule vital for maintaining flexible, relaxed blood vessels. "Powerful mouthwashes can eradicate these beneficial bacteria, potentially elevating blood pressure during a period when the body requires rest and recovery," he states.
2. Minimise Blue Light Exposure
Scrolling through devices before bedtime is a widespread habit, but Dr Lo Monaco warns that bright blue-rich light suppresses melatonin production. "Melatonin is not merely a sleep hormone; it serves as a potent antioxidant protecting blood vessels," he clarifies. Reduced melatonin levels can lead to increased oxidative stress in arteries over time, compromising vascular health.
3. Avoid Intense Static Exercises
Engaging in strenuous static exercises like planks, wall sits, or dead hangs late in the evening can elevate blood pressure for extended periods. Dr Lo Monaco notes, "After a stressful day, the nervous system is already overactive. Intense late-night strain perpetuates this state, hindering cardiac recovery. Prioritise vigorous training earlier in the day and opt for lighter evening sessions."
4. Reconsider Calming Supplements
While supplements such as green tea, containing L-theanine, are often used for relaxation, Dr Lo Monaco cautions that they can unpredictably interact with sleep and heart rhythm. "These substances influence the stress response and nervous system, which directly affects heart rhythm. Incorrect dosage or timing may disrupt natural cardiac patterns," he elaborates.
5. Refrain from Prolonged Breath-Holding
Although breathwork is popular for improving sleep, Dr Lo Monaco highlights risks associated with extended breath-holding. "It can lower oxygen levels and impose additional strain on the heart, particularly in individuals with pre-existing vascular or sleep issues. During REM sleep, blood is slightly more prone to clotting, making extra stressors inadvisable," he advises.
6. Implement a Three-Hour Pre-Sleep Fast
Dr Lo Monaco recommends fasting for at least three hours before bedtime to alleviate cardiac stress and enhance blood pressure regulation. "Eating too close to sleep forces the body to increase sympathetic activity when it should be resting. Fasting reduces endothelial stress, improves vascular flexibility, decreases oxygen demand on the heart, and promotes efficient overnight recovery," he concludes.
