New Delhi: Without spending much time outside, many people start their days by checking their phones or going directly to work. Even ten minutes of morning sunlight, according to medical experts, may have advantages beyond improving mood. Early exposure to natural light may help balance the body’s internal clock, enhance the quality of sleep and even promote better blood sugar regulation, according to research.
The National Institutes of Health (NIH) states that exposure to natural light soon after you wake up aids in synchronising the circadian rhythm, the body’s internal 24-hour clock that controls metabolism, hormone production, and sleep. Although morning sunshine is not a cure for diabetes or sleep difficulties, experts say it can be a straightforward lifestyle practice that promotes general health.
Why Early Morning Light Matters More
The timing of exposure to sunlight is crucial. Wavelengths in morning light cause the eyes’ specialised cells to fire, sending messages straight to the brain’s biological clock. The American Academy of Sleep Medicine (AASM) claims that this makes people feel more alert and prepares them for better sleep later in the evening by assisting the body in recognising that the day has begun.
Early daylight has the greatest impact on resetting the body’s natural sleep-wake cycle and maintaining circadian rhythms, in contrast to midday or evening sunlight.
Supporting Better Sleep Naturally
The impact of early sunshine on sleep is one of its greatest benefits. Melatonin, the hormone that causes drowsiness, is suppressed during the day by early daylight and increased after sunset. It may be simpler to fall asleep at night and wake up feeling rejuvenated thanks to this natural cycle.
According to the AASM, regular morning light exposure may enhance the quality of sleep, especially for those who have inconsistent sleep habits, insomnia, or who spend the majority of the day indoors.
Possible Role In Blood Sugar Control
Researchers are also investigating the impact of circadian rhythms on metabolism. Disruptions to the body’s internal clock have been associated with reduced insulin sensitivity and altered glucose management, according to a study published in Diabetes Care. Morning sunshine may indirectly promote improved blood sugar regulation by supporting a healthy circadian rhythm.
However, experts emphasise that diabetes cannot be prevented or treated by sunshine alone. Rather, it should be used in conjunction with a nutritious diet, regular exercise and any medical advice.
Who Can Benefit And How Much Morning Sunlight Do You Need?
For the first 1 to 2 hours after sunrise, health professionals advise spending 10 to 30 minutes outside; however, the optimal amount of time varies depending on the season, weather and skin type. Sitting behind a closed window is less effective than direct outdoor exposure because glass blocks out a large portion of the natural light that aids in circadian rhythm regulation.
Shift workers, senior citizens, office workers who spend most of the day indoors, those with erratic sleep habits and those going through seasonal mood swings may all benefit most from morning sunlight. While sunshine should supplement, not replace, medical therapy, people with prediabetes or type 2 diabetes may also benefit from maintaining a regular sleep-wake cycle in addition to their recommended treatment strategy.
Easy Ways To Make It Part Of Your Routine
You don’t need to make any significant adjustments to include early sunlight in your day. Daylight exposure can be obtained through gardening, taking a little stroll, stretching on a balcony, walking the dog, or having breakfast outside.
Consistency is more crucial than spending a lot of time outside, according to experts. Including morning sunlight in your daily routine may help you sleep better, boost metabolic health and promote healthier biological rhythms, proving that one of the most straightforward wellness practices may also be one of the most successful.
