Our retelling · details in the original publication
Returning to the UAE after a summer break often brings unexpected tiredness and lethargy. Doctors explain that switching from cool weather back to high heat and humidity forces the body to work significantly harder to regulate its internal temperature. This sudden environmental change creates physical stress just as you try to resume your daily routine.
The cardiovascular system works overtime to pump blood to the skin for cooling, which drains energy reserves. You might feel dizzy or unusually sluggish as a result. Research from the National Institute for Occupational Safety and Health (NIOSH) confirms that people lose heat-acclimatisation adaptations after being away for a week or more. This means your body essentially forgets how to handle the intense heat efficiently and needs time to readjust.
Disrupted sleep patterns and inconsistent hydration routines during travel add to this post-holiday fatigue, making the transition even harder. To cope, medics suggest gradually returning to normal activities and strictly prioritising hydration. It is wise to avoid intense outdoor exercise during the hottest parts of the day for the first few days back. Listen to your body and give yourself time to fully recover before jumping into a busy work schedule. Read more details in the original publication.
