Exercising is a crucial part of keeping ourselves healthy. Whether it is walking, going to the gym or even working out at the weekends, it is very important for your body. Everybody has their own preferences regarding exercising, while some people find it much better to exercise early, others go for evening exercises. Research published in the Medicine & Science in Sports & Exercise journal suggests that exercising in the morning could be especially good for the heart and lungs of older adults. The study also found that simply having a regular exercise routine can bring health benefits. Experts explained that getting physical activity earlier, consistently, and more often during the day might help you stay fit as you get older. What the Study Revealed To understand how the time we exercise affects our overall fitness and health, scientists looked at health information from 799 older adults (average age 76). Participants wore devices on their wrists for seven days to track their activity. They also underwent tests to check their heart and lung health and had regular doctor visits. Here's what researchers discovered: Being most active in the morning (what they called "peak morning activity") was linked to better heart and lung fitness and more efficient walking (meaning the body uses energy better while walking).Exercising at the same time each day consistently was connected to better health outcomes.People who had regular patterns of rest and activity throughout the day showed better heart and lung fitness and walking efficiency.Why Exercise Timing Might Matter There's still a lot to learn about how the timing of our physical activity affects our health and the risk of long-term diseases. More research is definitely needed to fully understand this link. However, researchers suggested that the connection between exercise and our body's natural circadian clock (our 24-hour internal rhythm) might explain why timing matters. This internal clock controls things like body temperature and hormone release. So, the time of day you're most active could actually impact how well you perform and even how your muscles respond at a very basic level. Depending on the timing, working out could also either shift your internal clock or keep it steady, which seems to help muscle cell function and overall metabolic health. Lastly, it's worth noting that everyone has a chronotype – whether you naturally feel more awake in the morning, afternoon, or evening. Scientists believe that knowing your chronotype and planning your activities accordingly could significantly impact your health and fitness. Should You Exercise in the Morning? The American Heart Association suggests getting 150 minutes of moderate exercise or 75 minutes of vigorous activity per week. But a growing amount of evidence suggests that even short bursts of movement – even just 20 minutes a week – can significantly benefit your heart. One sports medicine doctor emphasized that any amount of exercise makes a difference and that whether you exercise is more important than when. Another expert agreed, highlighting that having a consistent exercise schedule is also very important. Both the new study and other research show that sticking to a routine offers many benefits, from preventing long-term diseases to improving survival rates with cancer.
