    Jet lag and winter blues

    The HumanCharger® is ideal for alleviating symptoms caused by jet lag, and typical symptoms of winter blues caused by lack of sunlight.

    Jet lag is a physiological condition which results from alterations to the body’s circadian rhythms resulting from rapid long-distance time zone crossing (east-west or west-east) travel. Shift workers can also experience symptoms such as jet lag.

    Winter blues is also known as subsyndromal seasonal affective disorder (S-SAD). S-SAD is a milder form of seasonal affective disorder (SAD). SAD is a recurrent pattern of depressive symptoms during the fall and winter that remit in the spring and summer. S-SAD tends to affect sleep and energy especially, with some degree of effect on mood each fall-winter but, unlike SAD, S-SAD people do not fulfill criteria for major depression.

    Use HumanCharger® if you feel or experience the following symptoms related to winter blues or jet lag:

    irritability
    loss of interest in activities you usually find enjoyable
    feeling of worthlessness or hopelessness
    oversleeping
    loss of energy
    social withdrawal
    decreased physical activity
    fatigue
    cravings for foods that are high in carbohydrates
    weight gain

  • Between 2008-2010, researchers at the University of Oulu, Finland, discovered that in addition to eyes, areas of the human brain are also sensitive to light. This sensitivity is due to the photoreceptor-proteins in the brain, which are similar to those found in the eyes, a discovery that had been made by researchers in the U.K. and the U.S. 10 years earlier. University of Oulu researchers found that brain areas can be reached by light through ear canals, ear tissues and bones of skull. The skull of large mammals, including humans, lets light pass through naturally. In ordinary daylight and daytime conditions the brain is constantly being exposed to light.
