According to research those of us who like to sunbathe in the morning are more likely to be thinner than those who sunbathe later in the day.
Dr Kathryn Reid, the co-lead author of the study and research associate professor of neurology at Northwestern University Feinberg School of Medicine in Chicago had this to say:
“The earlier this light exposure occurred during the day, the lower individuals’ body mass index.”
“The later the hour of moderately bright light exposure, the higher a person’s BMI.”
What else was discovered?
This study, which was published in the journal PLOS ONE discovered that the influence of morning light exposure on body weight was independent of a person’s physical activity level, their calorie intake, the amount of sleep they had, their age and the season.
The researchers has suggested that it influenced around 20% of a persons BMI (Body Mass Index).
The senior author of the study Dr Phyllis Zee stated:
“Light is the most potent agent to synchronise your internal body clock that regulates circadian rhythms, which in turn also regulate energy balance.”
“The message is that you should get more bright light between 8am and noon.”
“If a person doesn’t get sufficient light at the appropriate time of day, it could de-synchronise your internal body clock, which is known to alter metabolism and can lead to weight gain.”
So there you have it, the amount of sunlight you receive can influence your weight. Well, according to this one study anyway.
The authors of this study indicate that to affect your BMI positively you should get 20-30 minutes of morning light. Just remember your suncream as you do not want to burn.
Also, sunbathing is not going to be enough for any real weight loss. You should still eat healthily, eating a diet full of fresh fruit, vegetables and lean protein, along with regular exercise to burn off any stored body fat.
