How Artificial Light affects Obesity

In 1879 the first light bulb was tested by Thomas Edison. With the invention of artificial light came the possibility of a world with a significant number of obese patients. The artificial light allows us to keep different schedules then what the human body naturally wants. It allows us to sleep during the day and play during the night. The human clock gets disrupted by the artificial lights. The University of Aberdeen, focuses on how the human clock struggles to stay in tune with the irregular meal, sleep and work schedules of the developed world, and how this might influence health and even cause obesity.(Dr. Cathy Wyse) The human body has circadian rhythms daily that includes sleep wake cycles. The difference between circadian rhythms and the environment is called "circadian desynchrony". It is believed that with circadian desynchrony it causes a decrease in the metabolism therefore leading to obesity and diabetes. Studies have been done on plants and animals that it is important for the internal clock and environmental rhythms to line up in order for them to stay healthy. It is possibility for humans as well. Diet and exercise are important to keeping the metabolism in check and therefore helping to keep the waistline in check. Staying on a regular sleep schedule, work schedule, and a good diet and exercise plan will help decrease circadian desynchrony.
