Dr. Bikky Chaurasia - internal medicine physician, Kokilaben Dhirubhai Ambani Hospital (Mumbai, India) - said that winter limits the body's exposure to sunlight, affecting physical and mental health.
Dr Bikky Chaurasia explains what can happen to the body at different times if not exposed to enough sunlight during the cold winter months:
One week
Reduced vitamin D production: The body produces less vitamin D, which is essential for bone health, immunity, and mood regulation. A week of lack of sun exposure is unlikely to cause a significant deficiency unless dietary vitamin D is inadequate.
Disrupted circadian rhythm: Sunlight helps regulate the production of melatonin, the hormone that controls sleep. Without sunlight, you may experience sleep disturbances.
Although the body's vitamin D stores may not be completely depleted in a week, initial symptoms may include mild fatigue and decreased immunity.
“Sunlight also affects serotonin, a neurotransmitter that controls human mood. Therefore, lack of sunlight can cause irritability, low energy and mild mood swings,” says Dr. Bikky Chaurasia.
Lack of sunlight for two weeks
Vitamin D deficiency becomes more evident: After two weeks, fatigue, muscle weakness, and bone pain may become more apparent, especially if dietary intake is inadequate.
Increased risk of mood disorders: Lack of sunlight can lead to more pronounced symptoms of depression and anxiety, especially in people prone to seasonal affective disorder (SAD).
Sleep disturbances: You may experience more serious sleep disturbances, such as difficulty falling asleep or staying asleep. Lack of sunlight can disrupt your circadian rhythm and affect your overall sleep quality.
A month without sunlight
Severe vitamin D deficiency: Long-term deficiency can weaken bones, impair the immune system, and affect muscle function.
Higher risk of SAD: Persistent feelings of depression, lethargy, and anxiety are more likely to occur.
Chronic sleep disorders: Prolonged disruption of the body's internal biological clock can lead to persistent sleep problems, affecting mental and physical health.
According to Dr. Bikky Chaurasia, getting enough sunlight every day is important for maintaining overall health. If you are not getting enough sunlight, you may want to consider getting vitamin D through your diet or supplements.
