If you're dedicated to a consistent exercise routine, you might be curious about the optimal time to work out. Morning, evening, or a combination of both? The best time may depend on your fitness goals, as different times of day offer unique benefits.
A recent study highlights that a consistent morning exercise routine significantly enhances heart fitness and overall well-being. Prior research indicates that workouts in the 3 hours after 8 a.m. may lower the risk of coronary heart disease and stroke. Morning exercise also promotes better blood flow, oxygen delivery, and heart function, contributing to reduced hypertension and cholesterol levels.
The body's circadian rhythm significantly influences overall health, with researchers gaining deeper insight into how it governs daily activities like work, meals, and exercise. Previous studies indicate that disruptions to the circadian rhythm can affect exercise performance and recovery time.
The study included approximately 800 older adults, averaging 76 years old. Participants wore wrist accelerometers for a week to track daily activity. They all underwent cardiopulmonary exercise testing to evaluate heart and lung function. Cardiorespiratory fitness reflects how effectively the heart, lungs, and muscles collaborate during physical activity.
Additionally, the study assessed participants' walking capability, a key indicator of healthy aging. Walking capability measures how effectively the body uses energy to move forward. Higher efficiency allows for longer walking distances and serves as an additional gauge of fitness.
The study showed that participants with higher activity levels during their active daily periods compared to their resting time, and whose peak activity occurred earlier in the day, exhibited better cardiorespiratory fitness and walking capability. This indicates that exercising earlier in the day may offer health advantages.
Incorporating early-morning exercise into your daily routine can be a powerful and worthwhile habit. The recent study suggests that individuals who exercise at the same time daily may enhance their heart and lung health as they grow older.

Recent research reveals that constipation is linked to a greater risk of heart attacks and strokes, with the danger escalating significantly in individuals who also suffer from high blood pressure. These findings underscore the importance of viewing constipation not merely as a digestive problem, but as a potential cardiovascular risk factor requiring serious attention.
Microplastics have become inescapable. We're ingesting them through food and water, and even inhaling them daily. These tiny fossil-fuel-based particles, smaller than 5 mm, have now been detected deep inside human bones, cartilage, and spinal discs. A recent study reveals that microplastics can penetrate bone tissue, including the marrow, where they may disrupt metabolic processes and harm skeletal health.
Ultra-processed foods now make up nearly 60% of calories in the average U.S. adult's diet. These highly manufactured items are increasingly dominating American eating habits. A major U.S. cohort study involving over 100,000 participants, found that those with the highest intake of ultra-processed foods had a 41% greater risk of lung cancer compared to those with the lowest intake.
