One of the major factors that influence health insurance premiums is the age of the policyholder. This is primarily due to the fact that as you age, the risk of developing diseases and medical conditions tends to increase. Also, as you get older, the chances of developing critical illnesses go up. Therefore, insurance providers increase the health insurance premium to offset this rising risk.
In addition to the above reasons, the cost of healthcare is also on the rise. This is another factor too that leads to a rise in health insurance premiums as you age. The bottom line is that the later you opt for a health insurance plan, the higher the premiums are likely to be.
