Lack of sunlight in winter can lead to vitamin D deficiency. It is very important for many important body processes. Let's find out why the body needs vitamin D.
Vitamin D helps in the absorption of calcium. If it is deficient, the bones can weaken and the risk of osteoporosis increases.
In winter, many people have seasonal depression. Vitamin D balances the serotonin levels in the brain and improves mood.
In winter, diseases such as cold and flu often increase. Vitamin D strengthens the immune system and protects against infections.
Vitamin D improves the function of insulin. This keeps the blood sugar level under control.
Vitamin D balances blood pressure and heart health. Its deficiency can increase the risk of cardiovascular diseases.
Shorter days and less sunlight in winter can lead to vitamin D deficiency. Try to stay 10—15 minutes in the light morning sun.
Include milk, yogurt, eggs and vitamin D supplements in winter. Taking vitamin D on time improves both bones, immunity and mood.
