Warm weather feels oppressive at high humidity because your sweat cannot evaporate effectively. Evaporation is how your body cools down; if the air is already saturated with moisture, this process works less effectively, making it feel warmer and stickier than the temperature would suggest. Air circulation and reducing indoor humidity help combat this.
How does humidity work in warm weather?
Air can hold a limited amount of water vapor, and warm air can hold more than cold air. The KNMI, in its explanation of humidity and dew point, also explains that terms like 'oppressive' weather are linked to very high humidity. On a summer day with a lot of moisture in the air, the air is, as it were, 'full.' Your skin then struggles to release moisture, making you feel sticky and preventing you from cooling down properly. This explains why 25 degrees with high humidity feels more oppressive than 30 degrees with dry air. Weerplaza describes how you can tell how oppressive it feels using the dew point: the higher the dew point, the sultrier the weather.
Why is it often more humid indoors?
Indoors, extra moisture is added through cooking, showering, drying laundry, and even breathing. If you open all the windows during warm, humid weather, you also bring humid outdoor air inside. Also, read what the ideal indoor humidity is.
What helps against that oppressive, clammy air?
There are two approaches that complement each other: air circulation and less moisture indoors. A fan does not cool the air, but it moves air across your skin, allowing your sweat to evaporate faster and making it feel more pleasant. You can read more about this in can a fan make a room cooler and does a fan really help to cool down.
In addition, you can lower the humidity by adding as little moisture as possible (use the range hood while cooking, close the door while showering, dry laundry outside) and by using a dehumidifier. Do you want to dry laundry faster indoors? Then read does a dehumidifier help to dry laundry faster.
Direct answer: Warm weather feels oppressive at high humidity because sweat evaporates poorly; a fan provides air circulation, and a dehumidifier reduces moisture indoors.

Overview: what helps in oppressive weather?
| Measure | Effect | Note |
|---|---|---|
| Fan | Air circulation, sweat evaporates faster | Does not cool the air itself |

Sleeping in oppressive weather
Oppressive air is especially unpleasant at night. Use the fan on a low setting, ensure sufficient ventilation, and keep the room as dry as possible. The Sleep mode of the TV26G is intended for the night. You can find more tips in how to keep your bedroom cool during a heatwave.
Experiencing complaints such as dizziness, breathlessness, or breathing problems during warm weather? Then consult your GP; general information can be found at the RIVM and the Longfonds. A fan or dehumidifier is not a medical treatment.

What is a comfortable indoor humidity?
Read our article on ideal indoor humidity; as a rule of thumb, dry air in the summer feels more comfortable than clammy air.
Does a fan help with high humidity?
Yes, the air circulation helps your sweat evaporate, although a fan does not lower the humidity itself.
Should I open windows during humid weather?
Only if it is drier or cooler outside than inside; otherwise, you bring extra moisture indoors.
Can I use a fan and dehumidifier at the same time?
Yes, they complement each other: one provides air circulation, the other reduces moisture.
