What should you do first thing in the morning for weight loss?

According to a new research from the Northwestern University Feinberg School of Medicine published on PLOS ONE, morning sun rays can help with weight loss.

The researchers asked the 54 participants, with average age of 30, to wear a wrist monitor that would measure their exposure to the sun for seven consecutive days.

At the same time, the participants kept a food and calorie diary. Apparently, people who woke up earlier and “bathed” in the morning sun had a lower body mass index (BMI), regardless of age, activity or diet.

But why are morning sun rays so beneficial for weight loss?

There are two possible reasons: The very early morning sun exposure helps your internal biological clock to be regulated properly. This means that you sleep easier and a good night’s sleep helps boost your metabolism and, thus, makes slimming down easier.

The second reason is that the morning light is brighter than the afternoon light because there is a greater volume of blue light in the early morning rays. The blue light has the best impact on the circadian rhythm. Circadian rhythm refers to any biological process that displays an endogenous, entrainable oscillation of about 24 hours.

The term ‘circadian’ derives from the Latin word circa, which means “around” (or “about”) and diem or dies, which means “day”. Despite the fact that circadian rhythms are endogenous, they adapt to the local environment based on extrinsic factors, the most important of which is daylight.

You only need 20-30 minutes of morning sunlight between 8am and 12pm to get the light your body needs to function properly.
