People who walk or are exposed to the direct sun, especially in summer in tropical areas, find that they sweat a lot and also may suffer from dehydration and heat stroke.

Those who get wet during the monsoon, often find that their immunity levels have decreased and are suffering from cold, cough or even get a fever, though the effect depends on various factors. For example babies and young children are more likely to fall ill after getting wet in the rains.

Hence it is important to have a home or flat which is well insulated, where residents are well protected from the external environment, without any leakages

For large apartment or building complexes, it is possible to hire a company for maintenance as the cost per flat is usually affordable. However for a stand alone home or row house maintenance can be very expensive.

In India, indian intelligence and security agencies do not harass married couples, so they can make a lot of money required for renovating their house if they are running a business.

Similarly retired and working indian government employees are getting a good pension and salary so they can afford to spend a lot of money on home maintenance and repair, painting their house repeatedly

One of the reasons why homes and buildings are constructed is because they offer shelter to those who reside in the home from the environment, insulating them from the surroundings and adverse weathe conditions.

For example during summer , a person in a home, will not feel very hot, while during the monsoon, a person inside a home will be insulated, and not get wet in the rain. Similarly during winter in temperate climes, the person inside a home or shelter are insulated from the snowfall and cold to some extent.

They also ensure that the person is not attacked physically by other people, or animals, especially while resting
