Limited exposure to sunlight and the presence of UV allows the process of cell membrane crystallization (VDAC), increased mitochondria metabolism and restructure of the amino acid combinations which will lead to 'shadow re-activation' of further spiral DNA chains. Particularly sensitive to these changes is the Pineal Gland, Ajna - the seat of the third eye, which is stimulated by this process and the increased activity results in sporadic releases of melatonin causing the sudden tiredness and desire for increased sleep. The accompanying changes to your circadian rhythms may be experienced in much the same way as the known symptoms of S.A.D. (seasonal affective disorder) which also has a summer counterpart which can effect production of seratonin as well as other hormonal imbalances. Consider your intake of fluoride within food stuffs, toothpaste and liquid drinks. Much written about the effect on the pineal gland without needing further expansion here.
The increased vibrations within the cells of the ear may cause excess pressure within the Eustachian tube leading to popping as well as high pitched buzzing or continuous toning and increased temple pressure. The intake of Zinc and Copper within food will increase the electro-chemical abilities of the nerves and neurotransmitters of the brain within the hypothalamus and pineal to allow a better translation of light to energy transfer. Sporadic interruptions in electrical activity due to increased highly ionised particles affecting the flow of charge will not only take effect on short term memory but increases in alzheimers and parkinson type symptoms. This will also manifest within external communication systems and breaks in internet, electrical, phone networks will be experienced.
As always, the emphasis must be to make the statement regarding consulting a medical consultant before considering any change of lifestyle or diet, however, in essence, to balance your sleep patterns requires a light, fresh, vegetarian diet (all the colours in each meal), plenty of water, plenty of fresh air, exercise and sunlight, avoid stressful situations, increase the number of things that bring you joy and most of all stay happy.
