Ventilation in homes and public places is often poor in winter because windows and doors are tightly closed to keep out cold air, allowing germs to circulate more easily. Winter air is particularly harmful for senior citizens and for those with underlying heart or lung conditions such as chronic obstructive pulmonary disease (COPD) and emphysema. Signs of dehydration include dry lips, dry skin and unexplained muscle cramps. Adding 30ml of coconut oil to bathwater can also help. Applying coconut oil at night is best avoided, as it may attract insects.
