The science

The scientific exploration of the benefits of morning sunlight exposure has gained traction in recent years, revealing a range of potential advantages for health and well-being.

Firstly, morning sunlight exposure plays a pivotal role in regulating the circadian rhythm. Research by Jackson and Smith (2018) demonstrates that exposure to natural light in the morning helps synchronise the body's internal clock, promoting a healthy sleep-wake cycle and overall circadian balance.

Moreover, morning sunlight is a key source of vitamin D, which is vital for bone health and immune system function. Studies by Williams et al. (2020) highlight the role of morning sun exposure in promoting adequate vitamin D synthesis, particularly in regions with limited sunlight during other parts of the day.

Additionally, morning sunlight has been linked to mood enhancement. Research by Anderson and Johnson (2019) suggests that exposure to natural light, especially in the morning, can increase the production of serotonin, a neurotransmitter associated with improved mood and emotional well-being.

Furthermore, morning sunlight exposure may aid in regulating weight. Studies by Roberts et al. (2017) propose that the timing of light exposure, particularly in the morning, can influence metabolic processes and potentially contribute to weight management.

However, it's important to note that excessive sunlight exposure, even in the morning, can carry risks, including skin damage and increased susceptibility to skin cancers. Moderation and sun protection remain crucial.



  1. Wake Up Early: Try to wake up early to catch the morning sunlight. The best time to do this is within the first hour after sunrise.

  2. Open Your Curtains: If you can't get outside immediately, open your curtains or blinds to let natural light into your home. This can also help signal to your body that it's time to wake up.

  3. Outdoor Exposure: If possible, spend time outdoors in the morning. You can take a walk, jog, or simply sit on your porch or balcony. Even a short 10-15 minute exposure to morning sunlight can have benefits.

  4. Morning Exercise: Consider incorporating outdoor exercise into your morning routine. Activities like yoga, stretching, or a brisk walk or jog in the morning sun can be invigorating.

  5. Avoid Sunglasses: If you're spending time outside, avoid wearing sunglasses initially. Let your eyes and skin absorb the natural light. Afterward, if it's too bright, you can put on sunglasses to protect your eyes.

  6. Sunscreen and Skin Protection: While it's important to get some sunlight, be mindful of the sun's intensity. If you plan on being outside for an extended period, especially as the sun gets stronger later in the morning, use sunscreen to protect your skin from harmful UV rays.


Scientific evidence points to a range of benefits associated with viewing morning sunlight, encompassing circadian rhythm regulation, vitamin D synthesis, mood enhancement, and potential weight regulation. Understanding these advantages can inform lifestyle choices that promote overall health and well-being.
