The answer isn't as simple as yes or no. There are so many factors that influence this decision, such as your location and season. To some, air conditioning is a necessity; to others, it's a luxury. The electricity bills in Australia are high and having air conditioning is an additional burden. However, while the cost of having air conditioning is high, it has its benefits, which include the following.
Better sleep
Sleeping in a hot room is always uncomfortable as you can't enjoy your sleep. You are sweaty and keep turning to find the perfect sleeping posture while keeping your body cool. It becomes uncomfortable, especially considering that even your body is producing heat. Fortunately, you can sleep better with an air conditioner as it keeps the room cool and provides the perfect temperatures for you to enjoy your sleep.
Better air quality
Air conditioning creates a healthier atmosphere by filtering out pollen, dust and other allergens from the air. It also reduces humidity which hinders the growth of mildew. It also reduces exposure to allergens which lowers the risk of suffering from an asthma attack.
Creates a cool environment
Air conditioning creates a comfortable environment for your workouts or even during warm summer afternoons. Working out in a hot environment is always uncomfortable as you're sweating too much compared to when you're in a cooler environment.
Less sweating also means less dehydration. The more you sweat, the more water you lose, but you can control the rate of sweating by having air conditioning. Exposure to excessive heat will lead to sweating which depletes water reserves, and if you are not replenished, you become dehydrated.
It also reduces the risk of suffering from a heat stroke. If you're in a room with excessive heat such that your body is struggling to regulate its temperatures, that could lead to organ damage if not rectified early enough.
Improves work performance
Temperatures tend to dictate how people work. For example, it's difficult to work in freezing temperatures, and the same applies to extremely high temperatures. How do you even concentrate when you're sweating profusely? It's an uncomfortable situation that derails your performance. Air conditioning will ensure that the temperatures are favourable and conducive for optimal performance.
Do you need air conditioning?
While there are some areas where you can survive without air conditioning, it's always good to have it as it will do more than just regulate the temperatures.
