The skin is the largest organ of the body and experiences the effects of a heatwave the most, compared any other organ. The increased heat levels and damaging rays from the sun can cause detrimental effects on the skin. Hence, it’s important to protect the skin by employing appropriate protection measures.

This includes using sunscreen, staying hydrated, and staying indoors as much as possible. After-care use is always good for when going out in the heatwave is an unavoidable circumstance.

Home remedies and replenishing the electrolytes in the body can be of great help in such a situation. Thanks to the effects of global warming, heatwaves are becoming more common during the summer months. But, its effects on the health of the body and the skin can be tremendous.

It is so easy to forget about the damage the sun can do, during a heatwave, when you’re out having fun.

The skin, being the most exposed organ of the body bears most of the brunt of the higher than normal temperatures in such surroundings. It loses its natural glow, becomes withered due to loss of water from the body, and experiences the effects of sun damage. Therefore, you are more prone to hyperpigmentation and sunburn.

Protecting the skin and the body during such atmospheric temperatures is imperative to avoid permanent damage or life-threatening effects like skin cancer.

There are measures to be taken all through the hot weather and especially during the heatwave to counteract its effects. Specific skin concerns need to be dealt with a wholesome skincare routine and after-care steps. The breakdown is explained in detail in the following sections.

Can a heatwave affect your skin?

Higher than normal temperatures are accompanied by increased humidity levels. This lasts for longer periods of time to classify as a heatwave. When the skin is exposed to such extreme weather conditions, vital functions are interrupted and the skin cells become damaged in the process.

Common effects of heatwave on the skin

Heat Rashes

The sweat produced by the sweat glands in the skin blocks the pores in the skin and produces prickly heat or heat rashes. Small bumps may develop on areas such as the arms, back, chest, and neck.

Swelling and redness are also often seen in the affected areas.

Heat Edema

The prolonged warm temperatures can affect the water retention capacity on the skin cells and cause it to increase. Extremities of the body such as hands and feet swell up and remain so for a few days until the body acclimatises to the heat.


Extended exposure to sunlight during a heatwave can cause the skin to literally burn because of the damaging UV rays. Redness, swelling, and tenderness are common symptoms. Blisters and peeling skin are also seen in many cases.

Hyperpigmentation and Tanning

UV rays increase melanin production in the skin, which is a brown pigment present in skin cells. More melanin equals to increase in pigmentation in the form of dark spots or sunspots. When larger areas are affected, the hyperpigmentation is often referred to as a skin-tan. Prominent tan lines are visible that demarcate the areas of the skin that were exposed to sunlight and those that weren’t.

Dry Skin

Dehydration from the high temperatures can make your skin dry and even itchy.

Fine Lines and Wrinkles

The damaging sun rays during a heatwave can impact the skin’s texture and smoothness by speeding up the ageing process. Fine lines start to appear prematurely and steal away the youthful appearance of your skin.

How to keep your skin protected during a heatwave.

Whether you are indoors or outdoors, always keep the skin protected so that minimal sun damage and heat damage occurs. Follow this routine as much as possible to avoid unnecessary effects like sun tanning, dark spots, redness, and rashes.

Timing is Key

Avoid going out in the sun during a heatwave, especially during the 12 pm to 4 pm time frame. This is when the UV rays are usually the strongest and most harmful.

Apply Sunscreen

Always, always, always apply sunscreen! This point cannot be emphasized enough. Pick a sunscreen or sunblock with a minimum SPF of 30 and apply it about 15 to 20 minutes before you step out of the house. Even if it is a little cloudy, sunscreen is mandatory.

Pick a sunscreen with zinc oxide or titanium oxide as these act as physical barriers against the UV rays. It is vital that you re-apply the sunscreen every two to three hours.

The effects of UV blocking agents in the lotion or cream start to fade away after this period. Try and transfer some sunscreen into a travel-sized bottle to keep it in your bag.

Reverse the Damage

A cream or serum rich in antioxidants that are specifically for tackling sun damage should be a part of your daily skin routine.

This will keep the skin protected and also tackle the sun damage effects as and when they occur.

Dress Right to Keep Protected

Wear full-sleeved tops and full-length bottom wear to keep the skin protected from direct exposure to sunlight. This might sound claustrophobic considering the high temperatures outside during summer. However, you can always pick soft materials and cotton clothing. Breathable fabrics will keep the airflow going and minimise sweat. 

Also, don’t neglect your hair.  Use hats to cover up your head and protect the hair and scalp from sunlight.  It’s better to be safe than be sorry later.

How to keep the skin hydrated during a heatwave.


Apply a moisturiser to keep the skin hydrated and nourished. Look out for keywords like ‘hydrating’ and ‘nourishing’ when you go shopping for a summertime moisturiser. These products are formulated to tackle dryness and associated itchiness as well.

Hyaluronic acid is also an ingredient to look out for in your moisturiser or serum. This chemical helps to lock in the moisture and keep the skin hydrated for long. Overnight moisturising masks can replenish the skin while you get your beauty sleep and keep it hydrated and supple for the next few days.

Use a Facial Mist

Carry along with you a facial mist and keep spritzing it every hour or so to keep the skin refreshed and hydrated throughout the day, especially when you are going to be out in the sun. Repeat this every four to five days depending on how parched your skin is.

A refreshing and oil-controlling toner is another great addition that you can make to your skincare routine. It will help open up skin pores and get rid of all the accumulated dirt and grime that is clogging your pores. This will eventually maintain optimal skin hydration levels.

Don’t forget to Exfoliate

A tip that you did not expect to come across when looking for ways to keep the skin hydrated during summer is exfoliation. Homemade scrubs or commercially available ones will help to remove all the dead skin cells. This will let the creams, lotions, and serums, that you use, be absorbed efficiently into the skin.

Drink Plenty of Water

Drink eight to 10 glasses of water every day as internally hydrating the skin is as important as using topical hydrating agents.
