Why Are We Hot At Night? Potential Causes

Understanding the causes of feeling hot at night is the first step to getting a better night's sleep. Here are some of the factors that can contribute to it:

Room Temperature

Heat Insulation

Humidity Levels

Air humidity plays an essential part in how we perceive heat at night. In fact, it can significantly influence our thermal comfort. Dry and humid air have opposite effects on our sense of warmth.

When air is dry, it has the ability to better evacuate heat from our bodies. This means that our sweat evaporates more quickly, which has a cooling effect. In regions where the air is naturally dry, hot nights can be more manageable, provided there's a way to properly ventilate the sleeping area.

Humid air, on the other hand, tends to make the heat more stifling. When humidity is high, it's hard for sweat to evaporate efficiently, as the air is already saturated with moisture. This has the effect of keeping the heat close to your skin, leading to particularly hot and humid nights, as it's harder for your body to cool down naturally.

Metabolic Activity

Metabolic activity refers to the chemical processes that take place in your body to maintain life. These processes produce energy in the form of heat, which can influence how warm you feel during sleep. Each individual has a different basic metabolic rate, which determines the amount of heat generated by the body at rest. Some people have a more active metabolism than others, which means they generate more heat even when at rest. As a result, they may feel hotter at night, and this can be exacerbated by a thick blanket or high room temperature.

Nightwear

The clothes you choose to wear to sleep also play an important role in regulating your body temperature during the night. In fact, they can have a considerable influence on how warm you feel. If you tend to feel hot at night, it's a good idea to wear the right clothing to maximize your comfort. Breathable, lightweight fabrics are the key to maintaining a pleasant body temperature while you sleep.

Natural materials such as cotton, linen and silk are known for their ability to allow air to circulate around your body. Cotton clothing, in particular, is often recommended, as cotton is an absorbent material that helps to keep your skin dry by wicking away sweat. This means that, even if you sweat slightly at night, cotton absorbs moisture and helps you stay dry, avoiding the uncomfortable feeling of dampness. Lightweight cotton sleepwear is therefore an excellent option for warm nights.

Synthetic or heavy clothing, such as polyester or flannel, should be avoided as they trap heat and sweat, making you feel hotter and more uncomfortable. Also, choose loose-fitting clothing that allows air to circulate freely around your body, rather than tight-fitting clothes that trap heat.

Medical Conditions

Several medical conditions can contribute to feeling hot at night, including:

• Fever: our body temperature is higher than usual, making us feel hot and sweaty.
• Hot flushes: common during menopause, but can also be linked to other hormonal or medical issues. They induce a sudden sensation of intense heat.
• Hyperthyroidism: this is a thyroid condition characterized by excessive production of thyroid hormones, increasing metabolism and leading to sensations of heat.
• Infections: especially febrile infections, increase body temperature.
• Inflammatory diseases: some inflammatory diseases result in hot flushes and a feeling of excessive heat.

Stress & Anxiety

Stress and anxiety can affect your autonomic nervous system, causing hot flushes and night sweats. This is often linked to the body's fight-or-flight response to stress. When you're stressed or anxious, your body can release hormones such as adrenaline, which can raise body temperature. What's more, stress and anxiety almost inevitably disrupt our sleep, which can make us more sensitive to heat. 

If you regularly feel hot at night and this disrupts your sleep, it's best to take steps to improve your sleeping environment, such as adjusting room temperature, choosing appropriate nightwear and investing in quality bedding. If the sensation of night-time heat persists or is accompanied by other symptoms, it's advisable to consult a healthcare professional to rule out any underlying medical conditions.

Tips For Keeping Cool At Night, Both In Winter And Summer!

Here are a few simple but effective tips to help you stay cool at night and turn your hot nights into refreshing, restful sleep!

Choose Appropriate Bedding

• Opt for lightweight, breathable cotton sheets, which help regulate body temperature.
• Use light blankets or summer quilts, rather than thick ones.

Ventilate The Bedroom

• Open your bedroom windows to let fresh air circulate.
• Use a ceiling fan or standing fan to maintain a gentle breeze.
• If possible, invest in an air conditioner to cool the room.

Reduce Humidity

• Use a dehumidifier to reduce humidity, as dry air can make you feel cooler.
• Avoid boiling water or taking hot showers just before going to bed, as this increases the humidity in the room. 

Choose Adapted Nightwear

• Choose lightweight sleepwear made from cotton or breathable natural fabrics.
• You can even consider sleeping without pyjamas if you feel comfortable.

Reduce Humidity

• Drink water regularly throughout the day to ensure you stay hydrated.
• Avoid drinking too much water just before bedtime to minimize waking up at night to go to the bathroom.

Limit Physical Activity In The Evening

• Avoid strenuous exercise late at night, as it raises your body temperature.
• Opt for gentler activities such as meditation or yoga to relax before bedtime.

Avoid Heavy Meals

• Try not to eat heavy meals shortly before bedtime, as digestion generates heat.
• Opt for light, balanced meals in the evening.

Turn Off Electronic Devices

• Electronic devices such as computers, televisions and smartphones generate heat. Switch them off or place them away from your bed.

Use A Cooling Pillowcase

• Pillowcases specially designed to stay cool can help regulate the temperature of your head and face.
• At MedCline, we've designed a brand-new cooling pillowcase for therapeutic body pillow, made from a fabric that stays cool all night long.
