Seasonal Affective Disorder (SAD)
• Seasonal Affective Disorder, otherwise known as SAD, is a common disorder during winter time, caused by the shorter days and lack of sunlight. We need at least fifteen minutes of direct sunlight each day in order to keep our Vitamin D at healthy levels. Due to the fact we spend a lot of our time indoors and lead sedentary lifestyles, Vitamin D needs to be taken as a supplement throughout winter, since it is virtually impossible to get enough Vitamin D from during this time.
• Another option for treating SAD symptoms is the herb St Johns Wort which improves mood and alleviates depression by increasing serotonin levels in the brain. SJW can be taken with Vitamin D, however it must not be taken alongside anti-depressants, or the oral contraceptive pill.
Other tips and ideas:
• If you can’t take yourself off somewhere sunny and tropical for a Vitamin D top-up, eat foods which naturally contain Vitamin D such as egg yolks, butter, and cod liver oil.
• Get outside whenever possible. Even if you only expose your hands and face to the sun during wintertime, this can still be sufficient to produce some Vitamin D.
