Sleeping during the rainy season can be both comforting and challenging. Especially while the sound of the rain can be soothing, yet the increased humidity levels can make it extremely difficult to find the right balance for a comfortable night’s sleep. Setting your aircon to a perfect temperature can help you achieve a restful sleep while maintaining energy efficiency. Here’s how to find the best aircon temperature for sleeping during the rainy season in Singapore.

Finding the Perfect Temperature

For a comfortable sleeping environment during the rainy season, experts generally recommend setting your aircon temperature between 23°C and 25°C. This temperature range balances cooling with humidity control, making it cool enough to combat the dampness in the air without being so cold that it disrupts your sleep cycle. Here’s why this range is ideal:

Why This Temperature Range?

Comfort	Sleeping in a room that’s too warm can lead to sweating and restlessness, while a room that’s too cold can cause shivering or interrupted sleep. Studies show that maintaining a steady room temperature between 23°C and 25°C allows your body to regulate its core temperature for restful sleep. Since the rainy season’s high humidity can make a room feel warmer, a cooler setting around 23°C may be ideal on more humid nights, while 25°C could be more comfortable on milder nights.
Humidity Control	During the rainy season, humidity levels tend to be higher, creating an atmosphere that feels stuffy and damp. High humidity can also increase the risk of mold and mildew growth, which isn’t just unsightly but can also affect your health, especially if you’re prone to allergies. Running the aircon at a moderate temperature between 23°C and 25°C helps dehumidify the room, reducing that uncomfortable, sticky feeling without needing to crank the temperature down to extremes.
Energy Efficiency	Setting the aircon to a comfortable but not excessively low temperature can help you avoid high electricity bills. Maintaining the temperature at 23°C to 25°C reduces the workload on the unit, lowering energy consumption. For every degree you increase your thermostat above 25°C, you could see a savings of around 6-8% on your energy bill. So, aiming for this range not only helps create a comfortable environment but also keeps energy costs down—a win-win during the extended use of the aircon in the rainy season.

Tips for Maximising Comfort and Efficiency

To get the most out of your aircon without sacrificing comfort, here are some useful tips:

1. Regular Aircon Maintenance

An aircon that’s regularly serviced runs more efficiently. Routine servicing by a reliable aircon service provider in Singapore ensures that filters are clean, coils are functioning correctly, and no leaks are present. Clean filters help maintain good airflow, which is essential for efficient cooling and dehumidification. Aim to have your aircon serviced every three to six months for optimal performance.

2. Complement with Ceiling Fans

Using a ceiling fan alongside your aircon is a great way to circulate cool air more effectively, which allows you to keep the temperature set slightly higher without compromising comfort. The fan helps distribute the cool air around the room, maintaining an even temperature and reducing the need to keep the aircon running at a lower temperature.

3. Close Doors and Windows

When your aircon is on, closing all windows and doors is essential to prevent humid air from entering. This small step makes a significant difference, as it prevents the aircon from working harder to cool the room, which in turn lowers your energy use and electricity costs.

4. Opt for Breathable Bedding and Clothing

Wearing light, breathable fabrics and using bed linens made from materials like cotton or bamboo can enhance the cooling effects of your aircon. These materials allow better airflow and help wick away moisture, keeping you comfortable throughout the night without needing to adjust the temperature.

5. Use Curtains and Blinds

Keeping your room dark and cool before bedtime is also helpful. Closing curtains and blinds during the day can keep out excess heat and humidity, reducing the room temperature naturally. This can make a big difference when you turn on the aircon, as the unit won’t have to work as hard to achieve a comfortable temperature.

Additional Benefits of Setting the Aircon Right

A properly set aircon during sleep can do more than just keep you cool. Here’s how finding the optimal temperature also improves health and wellness:

1. Better Sleep Quality

Research shows that sleeping in a cooler room enhances REM (rapid eye movement) sleep, which is essential for mental and emotional health. REM sleep can be harder to achieve in overly warm or humid environments, so a room that stays within the 23°C to 25°C range can make a difference in how restful your sleep is.

2. Reduced Allergy Symptoms

Lowering humidity can also help prevent dust mites and mold from thriving. Aircons, especially those equipped with HEPA filters, capture allergens like dust, pollen, and pet dander, making it easier to breathe and reducing allergy symptoms. For allergy sufferers, regular filter cleaning is key to maximizing these benefits.

3. Enhanced Metabolism

There’s evidence to suggest that cooler temperatures may support better metabolism. When you sleep in a cooler environment, your body works slightly harder to stay warm, which can increase calorie burn overnight. Although not a major calorie-burning activity, this added boost to your metabolism can contribute to a healthy lifestyle.

Final Thoughts

Finding the right aircon temperature to sleep comfortably during the rainy season doesn’t have to be complicated. Setting your thermostat between 23°C and 25°C offers the best balance of cooling, dehumidification, and energy efficiency. With a few adjustments, like adding ceiling fans, using light bedding, and keeping your aircon well-maintained, you can optimize your sleeping environment for restful nights and reduced energy costs.

Remember, it’s the simple practices that often lead to the most effective outcomes. By making these minor adjustments, you can enjoy the comfort of a cool, humidity-free room that helps you wake up refreshed and ready to face each day — rain or shine!

Do you prefer sleeping with the fan, aircon, or both switched on simultaneously? Well, if you love sleeping with the aircon switched on, you’d be glad to know that it can offer a multitude of benefits that go beyond just cooling your room. For many living in hot and humid climates like ours, aircon can significantly improve sleep quality and overall well-being. Curious to learn more? Read on.

1. Improved Sleep Quality

Do you sleep like a baby? One of the key benefits of sleeping with the aircon switched on is the improvement in sleep quality. The National Sleep Foundation recommends keeping the bedroom around 23-25°C to optimize sleep. Aircon makes it easy to set a consistent temperature, helping you avoid waking up from overheating or night sweats. Cool air also supports deep sleep, allowing your body to progress through each sleep stage properly, which is crucial for mental and physical restoration.

Pro Tip: If you’re new to sleeping with an aircon, experiment with different settings to find what’s most comfortable. Try turning on a timer so the aircon switches off after a few hours if you’re concerned about energy usage.

2. Reduced Humidity

We live in a tropical climate, and that is often followed by high humidity levels. In turn, that will make it difficult to sleep comfortably. High humidity not only disrupts sleep but can also contribute to sweating, which can soil bedsheets and mattresses more frequently. Aircons are designed to not only cool the air but also remove excess moisture, creating a drier, more comfortable atmosphere. Lower humidity levels prevent the development of mold, dust mites, and mildew, which thrive in damp environments.

Pro Tip: A dehumidified room also reduces the chance of respiratory issues linked to damp environments, making it easier to breathe. For the best results, consider aircon units with built-in humidity control or pair your aircon with a separate dehumidifier if humidity levels are consistently high.

3. Noise Reduction

The latest aircon models are designed to operate quietly, providing a peaceful environment to sleep in. In urban environments, keeping windows open at night can let in noise from traffic, neighbors, and other disturbances. When windows are closed, the aircon also helps block external noise, creating a quiet space ideal for sleeping.

Pro Tip: If your aircon is older and noisier, try a “sleep” mode if it has one. This feature often adjusts the fan speed to a quieter level while still keeping the room cool.

4. Health Benefits

We often hear of the negatives, but let’s focus on the positives, shall we? Believe it or not, sleeping in a cool room can contribute to various health benefits. A cooler environment helps regulate melatonin production, a hormone associated with the sleep-wake cycle and even anti-aging benefits. Additionally, a stable, cool temperature aids metabolic function and prevents dehydration by reducing the need for your body to work harder to cool down. Keeping your room cool also improves the body’s overall thermoregulation, potentially leading to better heart health, improved cognitive function, and increased daytime energy.

Pro Tip: Research suggests that cooler sleeping conditions may also support metabolic rate. This means that if you’re sleeping in a cooler environment, your body could work slightly harder to maintain warmth, potentially contributing to a minimal calorie burn overnight.

5. Allergen Control

Aircons can help filter out allergens such as pollen, dust, and pet dander from the air. This makes it easier for those with allergies or asthma to breathe comfortably. Clean air filters help trap these particles, ensuring the air you breathe is fresher and cleaner. Over time, a properly maintained aircon unit can reduce allergens in your bedroom, providing better breathing and fewer respiratory irritations.

Pro Tip: Keep your aircon well-maintained for optimal allergen control. Dirty filters can become less effective and may circulate dust and allergens if not regularly cleaned or replaced. Aim to clean the filters monthly, especially if you live in a high-pollution area or have pets.
