THE LIGHTER SIDE
Light therapy is understood to affect brain chemicals linked to mood and sleep. Mimicking daylight, it’s commonly used by people with seasonal affective disorder (SAD) but has also been used to treat dementia, depression and even cancer-related fatigue (CRF). Patients undergoing chemotherapy can experience disrupted circadian rhythm, and recent research showed that correcting their sleep-wake cycle with light therapy could decrease CRF.
Correcting circadian rhythm can also help jet lag. Although it’s unclear why, studies have shown that recovery from it is worse for women and for older people in general. In addition to feeling tired at the wrong time, crossing time zones can cause dizziness, headache, irritability, indigestion and even memory loss. To help right your rhythm, use light therapy the morning of departure – if you’re going east – or in the evening – if you’re going west – for 30 to 60 minutes the day of travel and 15 to 30 minutes the day after. Medicine Hat-based The Litebook Company offers two light therapy boxes including The Edge, a portable smartphone-sized model ideal for travel.
