The destructive effect of COVID-19 outbreak is still continuing. On the other hand, the summer heat waves are worsening people’s health conditions. In this scorching heat it is quite annoying to stay inside large commercial places, industries, offices and even homes. However, many people are asking whether using Air Conditioners (ACs) during COVID19 pandemic is safe. For several months debates are going on this issue among scientists, engineers, authorities and general people. However, let’s discuss some guidelines about how to use ACs (Air Conditioners) safely amid COVID19 pandemic.
Considering the climate of Sub-continent countries, ISHRAE (The Indian Society of Heating, Refrigerating and Air Conditioning Engineers) has recommended some guidelines regarding how to run air conditioners safely during the coronavirus pandemic. These suggestions can be helpful for operating ACs in different commercial and industrial places in Bangladesh.
What would be the ideal air conditioner temperature for your room during the COVID19 pandemic? According to the recommendation of ISHRAE and CPWD, for any home-run AC, like Room AC, Split AC or Window AC, the temperature level of should be kept within the range of 24 to 30 degrees centigrade.
In addition to this, ISHRAE emphasizes to maintain the relative humidity of indoor environment. You can easily check the humidity of your surrounding ambient through downloading any ‘Weather App’ on your Smartphone. The ISHRAE guideline says that the humidity of an indoor environment should rest between 40 and 70 percent.
Therefore, if you are living in humid climate, then you need to keep the AC on ‘cool’ mode and set the temperature closer to or at 24 degree centigrade. On the other hand, when you are staying in a dry climate area, then you must set the temperature close to or at 30 degree centigrade.
ISHRAE report states that when we breathe dry air, the mucous membrane of our lungs becomes dry. It thickens the fluid over lining of the cells, and hampers the actions of cilia – the little hairs which protect the lungs from deep settling of harmful and non-harmful particles. As a result, the alien particles can settle more deeply inside our lungs.
To prevent such mishaps in the dry climate zones, ISHRAE suggests running electric fans to enhance the air circulation while AC is operating. You can also apply exhausting electric fans which will push the hot air outside the room. However, you need to clean the fan blades frequently to keep the indoor air clean.
What precautions should be taken while using ACs? Instead of allowing recirculation of the same air inside an indoor space, ISHRAE also suggest keeping the windows slightly open to let the fresh outdoor air enter the room.
When you are staying in a room, keep the opposite-facing window and door slightly open to promote cross-circulation of fresh cool air. Though opening a window or door – while running AC – might lose some cool air and cost you more electric bill at month-end, it can help to keep the indoor air fresher.
What precautions should be taken when you are using an evaporative cooler or dessert cooler? To combat the soaring temperatures, you can fit in an air filter in an evaporative cooler in order to keep the dust away and preserving hygiene of the indoor environment. However, make sure that your cooler is capable of drawing outdoor air efficiently to assist proper ventilation. The opposite-facing windows and doors must be kept open slightly to reduce humidity.
Besides, evaporative cooler, other type ACs must be fitted with filters. The ISHRAE guideline recommends cleaning and disinfecting the air cooler on a regular basis. More importantly, the released water must be drained and refilled frequently. The routine servicing of AC is also necessary to avoid any malfunction.
And, the opposite-facing windows must be kept open to ensure proper ventilation. ISHRAE guideline discourages people to use the portable air coolers that can’t draw fresh air from the outdoor environment.
According to the views of engineers and health-experts, using the window air conditioners at residential setting can be safe if the people who share the space with don’t carry corona virus. However, problem may arise when you are staying in a building which uses central cooling. If one infected person stays inside the building, the central air cooler poses a high risk of spreading the corona virus to other people staying there unless adequate precautions – such as, outdoor air ventilation, temperature and humidity control, AC filtering procedures, etc – are taken properly. These central air conditioning systems are widely used in shopping malls, government offices, hospitals, corporate workplaces, industries, etc. So think before you enter those places!
Vitamin C is one of the most essential nutrients for human-body. During the ongoing Coronavirus pandemic many health experts are advising people to consume Vitamin C every day. The recommended Daily Value (DV) for vitamin C for an adult is about 90 mg for male and 75mg for female per day. However, a breastfeeding mother requires an extra 30 mg and an individual who consumes tobacco needs an extra 35 mg per day. You can easily consume the required amount of Vitamin-C through eating variety of fruits, nuts and vegetables. Read this article to know the benefits and food sources of vitamin C.

June 8 is World Oceans Day!
The United Nations marks the day celebrating the role of the oceans in our everyday lives and inspiring action to protect the ocean and sustainably use marine resources.
Many countries also celebrate this special day since 1992, following the United Nations Conference on Environment and Development, held in Rio de Janeiro that year.
This year, the theme of the day is, 'Innovation for a Sustainable Ocean'.
This year's theme is especially relevant in the lead-up to the UN Decade of Ocean Science for Sustainable Development which will run from 2021 to 2030.
The Decade will strengthen international cooperation to develop the scientific research and innovative technologies that can connect ocean science with the needs of society.
"As we enter the United Nations Decade of Ocean Science for Sustainable Development (2021-2030), it is indeed our responsibility to seize this moment. We must seize this moment, firstly, to learn more about these depths, which often remain largely unknown to us, and still hold many secrets that only we can reveal... secondly, to give free rein to imagination and innovation, which we need in order to confront this worrying situation,” said Audrey Azoulay, Director General of UNESCO, on the occasion of World Oceans Day.
“This is why we have made innovation the theme of the celebrations of this international day. We must also seize this moment to sound the alarm, perhaps more widely than we have done so far, because no technical solution can replace a widespread, personal understanding of the threats to the oceans, their mysteries and their beauty," said Audrey Azoulay.
World Oceans Day provides an opportunity to honor, help protect, and conserve the ocean.
