Why your sleep patterns may change during the UAE winter

As Dubai transitions from the scorching summer to the milder winter months, residents may experience shifts in their sleeping habits. While cooler temperatures can make it more comfortable to rest, the seasonal change can also impact sleep quality through alterations in daylight, indoor humidity, and daily routines.

Experts warn that there is no single cause for these changes. Some individuals may sleep better as temperatures decline, while others could face disrupted sleep due to allergies, an uncomfortable bedroom environment, or irregular schedules.

Dr. Rashmi Fernandes, an ENT specialist at RAK Hospital, explains that the cooler weather can provoke vasomotor rhinitis, a condition causing nasal congestion and sneezing. Lower humidity levels may dry out the nasal passages, potentially leading to nosebleeds. Additionally, winter winds and respiratory infections may irritate the throat and disrupt sleep.

The shorter days of winter can also confuse the body's internal clock, causing earlier release of melatonin, which makes people feel sleepy sooner. Reduced morning light contributes to lower cortisol levels, leading to decreased daytime energy. Serotonin levels, influenced by daylight hours, may affect mood and sleep as well.

Noise changes also play a role. As people rely on air conditioning less in the cooler months, the quiet environment can be unfamiliar and disruptive. To cope with these changes, specialists recommend maintaining a consistent bedtime routine, dimming lights before sleep, and limiting screen time in the evening. Gentle morning walks and daytime outdoor activities can help maintain alertness.

For nasal dryness and congestion, isotonic saline nasal sprays can provide relief. Adjusting the air conditioning to a comfortable temperature rather than an excessively cold setting is also advised. Bedroom humidity levels should be balanced - too dry can irritate the nose and throat, while excessive humidity makes the room feel warm and uncomfortable.

While many seasonal sleep disturbances stem from the weather, other factors such as stress, caffeine, late-night screen use, health conditions, and irregular schedules can also impact sleep quality. If sleep problems persist and affect daily functioning, residents should consult a medical professional. By establishing a regular sleep schedule, exposing oneself to morning sunlight, staying active, and ensuring a cool, dark, and quiet bedroom environment, the UAE's residents can navigate the seasonal sleep changes more smoothly.
