If you feel lethargic all day, tired and annoyed, overstimulated, inconsistent with your energy and painfully sluggish at times, it is not just about motivation or what you are eating. It could be a circle of bad timing! Didn\u2019t understand? Let us explain. Your body runs on an internal 24-hour clock. This clock likes to control and regulate your energy levels, hunger, performance, recovery and even metabolism. So what happens when you do not provide its timely needs? \u201cSunlight before screen light\u201d is a trend gone viral to make people realise that they need to start respecting their body\u2019s clock. Light exposure is a strong signal to your body\u2019s clock. Let us understand your body\u2019s cues and how you can help yourself get fitter by giving the right cues to your body.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Circadian Rhythm and Fitness<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The circadian rhythm is your body\u2019s clock to regulate the release of hormones, body temperature, alertness, digestion and muscle coordination throughout the day. From a fitness perspective, this rhythm determines:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>When you feel energetic without an external stimulus<\/li>\n\n\n\n<li>When your muscles generate maximum force<\/li>\n\n\n\n<li>When your fat oxidation peaks<\/li>\n\n\n\n<li>When recovery and tissue repair are most efficient.<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\"><\/ol>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Research published in Chronobiology International shows that strength, flexibility and endurance are usually at peak from late afternoon till early evening. This is also when the core body temperature is increased and neuromuscular coordination peaks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">While working out is great, it is not advised to work out against your natural circadian rhythm. For example, working out late at night, compromising on sleep, or having more screen time can reduce the benefits of your workout.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"900\" height=\"500\" src=\"https:\/\/blog.muscleblaze.com\/wp-content\/uploads\/2025\/12\/Blog-_38.jpg\" alt=\"Sunlight Energy Benefits for Exercise\" class=\"wp-image-3436\" srcset=\"https:\/\/www.muscleblaze.com\/blog\/wp-content\/uploads\/2025\/12\/Blog-_38.jpg 900w, https:\/\/www.muscleblaze.com\/blog\/wp-content\/uploads\/2025\/12\/Blog-_38-300x167.jpg 300w, https:\/\/www.muscleblaze.com\/blog\/wp-content\/uploads\/2025\/12\/Blog-_38-768x427.jpg 768w\" sizes=\"auto, (max-width: 900px) 100vw, 900px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Sunlight Energy Benefits for Exercise<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Sunlight is the most powerful cue to your body and its circadian rhythm. Morning light exposure sends a clear message to your brain that the day has begun, and the tasks are lined up for the body to do. Here is how this helps your body:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Improves your energy and alertness by suppressing melatonin, aka the sleep hormone.<\/li>\n\n\n\n<li>Studies show that morning light exposure can improve hormone regulation and reduce insulin sensitivity.<\/li>\n\n\n\n<li>In 2021, a study published in Sleep Health spoke about how people, when exposed to early daylight, experience better sleep later in the night.<\/li>\n\n\n\n<li>Sunlight helps to enrich our bodies with Vitamin D. Sunlight exposure does just that, but it is beneficial to absorb the sunlight only early in the morning.<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\"><\/ol>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Sleep Cycle Hacks for Energy and Workouts<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Getting good sleep is not just about how long you have slept but about how deeply you have slept. Here are a few sleep cycle hacks for a consistent flow of energy during workouts<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Going to bed and waking up at a consistent time can help you go into REM and deep sleep easily. This can also improve your performance and reaction time.<\/li>\n\n\n\n<li>Keep high-intensity or strength training for morning or late afternoon<\/li>\n\n\n\n<li>Yoga and walking are evening-friendly workouts to feel more relaxed before bedtime.<\/li>\n\n\n\n<li>Dim lights after 8 pm<\/li>\n\n\n\n<li>Avoid screens about 1 hour before bed<\/li>\n\n\n\n<li>Use warm lighting at night.<\/li>\n\n\n\n<li>Heavy meals, especially later at night, can disrupt the sleep cycle, so have a light dinner.<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\"><\/ol>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Circadian Rhythm Hacks for Athletes<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Athletes and fitness enthusiasts can improve performance by syncing training with their biological clock by:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Training at the same time daily<\/li>\n\n\n\n<li>Having a morning sun exposure workout, like a simple 10-minute walk outdoors.<\/li>\n\n\n\n<li>Using bright lights in the morning, but dim and warm lights in the evening<\/li>\n\n\n\n<li>For those with rotating shifts, you can figure out the best exercises to do in the evening and morning and stick to them.<\/li>\n\n\n\n<li>Fixed meal time can help reset the clock better.<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\"><\/ol>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Read Also:<\/strong> <a href=\"https:\/\/blog.muscleblaze.com\/generalfitness\/why-sleep-might-be-the-most-underrated-fitness-tool\/\">Why Sleep Might Be the Most Underrated Fitness Tool<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Takeaway<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Fitness is not just built in the gym. It is also built into every habit you incorporate. Your body\u2019s internal clock keeps giving you cues for your task. Pay attention to those cues. Have <a href=\"https:\/\/www.muscleblaze.com\/categories\/vitamin-supplements\/multivitamins?navKey=CL-5738\">multivitamins <\/a>if you feel there is a need to push your body beyond the meals and <a href=\"https:\/\/www.muscleblaze.com\/categories\/fit-foods?navKey=CL-4965\">fit foods <\/a>to replace foods that are not aligned with your healthy habits. Fitness is about syncing your body to the tasks it is meant to do at the time, which is right for it.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Hello Ziddis!
