Melatonin is involved in the regulation of the sleep-wake cycle, circadian rhythms, and seasonal changes in the light dark cycle. Commonly used to induce sleep, some (but not all) find it to reduce jet lag. There is a high concentration of melatonin in the pineal gland, where it is manufactured. I was surprised to learn that there are significant amounts of melatonin present in the gastrointestinal tract.
In 2014 the average dual fuel reached an eye watering Â£1,344. The average electricity bill was Â£592 and the average gas bill was Â£752. But averages can be confusing. So to give you a better idea of how your own bill compares weâve estimated the total bill for small, medium and large users in the chart above.
This, in addition to the costs of running a retail business with billing and sales, accounts for 67% of a gas bill and 58% of an electricity bill, according to Ofgem. But this is where the figures get really complicated. Wholesale gas and electricity is not a single product but a whole series of contracts.AT accounts for 5% of each. A bit goes on costs of metering and storing gas. Then, 6% of a gas bill and 11% of an electricity bill went to government schemes aimed at saving energy, reducing emissions and tackling climate change.
