A Guide to the Most Common Illnesses During the Summer Season

​​The dry season in the Philippines falls within the months of March to May. More commonly known as summer, this is the period when people usually go to the beach or air-conditioned shopping and dining establishments to escape the heat. However, due to the ongoing pandemic, we’re advised to endure the heat in the safety of our homes.
During this season, certain diseases are more common due to rising temperatures that can reach dangerous levels. It is also ideal for pathogens to thrive and spread in such conditions. Summer sicknesses range from sore eyes to skin conditions and asthma—the list goes on. Health problems arising from these illnesses should not be ignored, nor should they prevent anyone from having a relaxing summertime.
The following infographic discusses the most common illnesses that people need to watch out for and some tips for staying healthy during the summer season.


A Guide to the 10 Most Common Summer Illnesses

The hottest season of the year is the time when various summer sicknesses occur. Here are things to know about a particular disease’s nature, symptoms, and prevention and treatment options.

1. Asthma

Heat and humidity can trigger asthma symptoms like coughing and shortness of breath, as lack of air movement can trap pollutants like dust and molds into the airways.
Staying cool amidst the summer’s extreme heat is crucial in preventing asthma attacks. Taking shelter in clean, cool, and well-ventilated places should help someone with asthma combat the heat. Medications need to be close by as well, just in case of a sudden attack.

2. Chickenpox

Chickenpox is a viral infection that typically affects children, which is why the first dose of varicella vaccine should be given to kids between ages 12 and 15 months and the second dose from age 4 to 6.
Initial chickenpox symptoms include fever and headache, while rashes may start appearing a week after exposure to the virus and develop into blisters that take several days to heal. Since chickenpox can be transmitted through direct contact with the rash or inhalation of air droplets, those who are sick should avoid going to public areas to prevent the infection from spreading.

3. Conjunctivitis (sore eyes)

In sore eyes or conjunctivitis, the outer lining around the eyeball and the inner lining of the eyelid become inflamed. This may be due to a viral or bacterial infection that thrive during the season, an allergic reaction, or trauma. The conjunctiva—or the covering of the white part of the eyes—may show redness, with noticeable itching and discharge around the eyes, too.
The best and easiest way to avoid getting sore eyes is frequent and thorough hand washing, as this removes bacteria or any other foreign substance from the hands so they do not get into the face or eyes.

4. Flu

Although influenza viruses are also prevalent in cold weather, they can still cause summer flu. Weather changes, like sudden downpours or temperature shifts from hot outdoor to cool indoor environments and vice versa, can make someone susceptible to respiratory diseases like cough and colds. Other symptoms of flu include fever, muscle aches, and headache.
Bedrest, antiviral medications, and adequate fluid intake are effective in alleviating flu symptoms.

5. Food poisoning

Foodborne illnesses are twice more common during the summer season than other months of the year since food spoils easily—no thanks to bacteria that thrive on warm weather conditions. Contaminated food and drinks can cause diarrhea and vomiting, which can lead to dehydration and, possibly, complications for those with chronic health conditions.

It is best to avoid eating perishable foods one to two hours after being left out of the refrigerator or as soon as the food develops molds or an unpleasant smell.

6. Hyperthermia

Hyperthermia is a condition where the body temperature becomes abnormally high, signaling that it cannot regulate heat coming from the environment. Heat exhaustion and heat stroke are medical emergencies that fall under hyperthermia.

A person suffering from hyperthermia may experience headache, dizziness, disorientation, fainting, heavy sweating, and cramps. Avoid strenuous activities or going outdoors in the middle of the day when the sun’s heat is at its peak.

7. Measles

A condition transmitted in the same way as chickenpox, measles is another example of a childhood illness that spreads during summer. The rubeola virus causes measles, with symptoms that include dry cough, high fever, runny nose, and reddening of the eyes.
Measles can also cause complications ranging from ear infections to pneumonia, including pregnancy problems for women. The MMR (measles, mumps, and rubella) vaccine is a way to give people immunity against the disease.

8. Mumps

Mumps is an infectious disease caused by a paramyxovirus that is spread through an infected person’s droplets of saliva. It is concentrated around the salivary glands near the ears, causing them to swell. This inflammation on one or both sides of the face may cause pain or difficulty in chewing or swallowing. Mumps may also be accompanied by a fever, headache, and muscle pains.
In most cases, mumps does not progress into a serious disease and can be eased by applying a warm or cold compress and taking pain relievers. However, people at risk of complications, such as pregnant women, should see a doctor specializing in infectious diseases.

9. Rabies

Summer outdoor activities can increase chance encounters with rabies-infected animals like cats, dogs, and bats, to mention a few, as they go to areas where they can find food or water. When someone exposes their broken skin to an infected animal’s saliva or is bitten by the animal, the rabies virus can then be transmitted to humans.

Preventive measures against rabies include vaccination of house pets and avoiding feeding wild animals. Those who were bitten by rabid animals should get rabies vaccination immediately.

10. Skin conditions

Sunburn is a common skin condition that happens when someone is in direct and prolonged exposure to the sun. The intense heat can cause first-degree burns with skin redness and peeling or second-degree burns with blisters.

Sunscreen with at least an SPF of 30 is the best preventive measure against exposure to harmful UV rays, while cool baths and moisturizers can ease the pain or discomfort from sunburns. In severe cases, a medical checkup may be necessary to treat skin blisters.

Tips for a Healthy Summer

The arrival of summer brings seasonal changes that can make some people vulnerable to certain illnesses. Here are some helpful tips to help everyone stay healthy this summer.
  • Hydration. Drinking around two (2) to three (3) liters of water every day ensures that the body replenishes lost fluids due to profuse sweating. Cutting back on alcohol and caffeine can help keep someone well-hydrated, too, as these drinks tend to make the person urinate more, further depleting the body of fluids.
  • Protection from the sun. Wear protective coverings like hats or caps and sunglasses. Sunscreen or sunblock has to be applied to the skin about 30 minutes before going outdoors. It is also necessary to re-apply the product every two (2) hours, especially after swimming or sweating.
Broad-spectrum sunscreens protect the skin against UVA and UVB rays, which are responsible for skin aging and sunburn.
  • Proper hygiene. Many summer diseases are caused by viruses that can be eliminated through regular bathing and handwashing. Alcohol and hand sanitizers should be kept handy when traveling.
  • Eating habits. The hot summer months may give way to unhealthy cravings like sugary sodas, ready-to-eat processed snacks, or street foods. A healthy diet for summer includes fiber-rich foods like grains, fruits, and vegetables, as these keep hunger pangs in control and prevent someone from mindless eating.
  • Lifestyle choices. Getting enough sleep and engaging in low-intensity exercises help boost the immune system. If possible, stay home and pursue worthwhile activities to calm the body and keep away from the sweltering heat outdoors.

Summer Is In

High summer temperatures can bring health woes, and nobody wants that. Staying cool by drinking plenty of water, eating healthy, and spending time indoors can help beat the summer heat and avoid getting sick.
