  • Environmental vulnerability

    Any exposure to stressors, toxic substances, or chemicals that can lead to inflammation in the womb of the mother can cause illnesses related to mental health. For example, the consumption of alcohol, drugs, or any other toxic substances can lead to mental illness in a child.

Benefits of Purchasing a Health Insurance Plan

With the rapidly increasing costs of healthcare, a medical insurance plan ensures that you have financial support when you require it. Technological advancements have provided access to many new treatments for various diseases, but with added costs. The expenses of treatments have increased, and without a health insurance plan, getting the right treatment can prove to be expensive.

Here are the top benefits of purchasing the right health insurance:

- Range of illnesses

A health insurance plan does not cover only one or two illnesses; it covers a host of illnesses. The medical insurance plan states all the illnesses that are covered under the plan. Even pre-existing diseases are covered by your medical insurance plan after the waiting period is over. Also, most health insurance plans cover a range of mental health issues which is one of the top advantages.

- Medical emergencies

Illnesses or any medical emergencies can happen at any time. They do not announce before they happen. Thus, with a medical insurance plan, you can be assured of the right treatment and financial support when there is a medical emergency. You do not have to take money out of your savings to pay the hospital bills if you have a suitable health insurance plan.

- Cashless hospitalisation

A top benefit of a medical insurance plan is the choice of cashless hospitalisation. If you get hospitalised and seek treatment at one of the network hospitals of the insurance company, you will not have to pay bills out of your pocket. The bills will be settled by the insurer, subject to the conditions of the medical insurance plan.

- Peace of mind

After purchasing a health insurance plan, you will have peace knowing that you have the right coverage against different mental and physical illnesses.
