Why Does Time in the Sun Make You Feel Tired?

If you’ve ever spent a long day at the beach or out enjoying the sunshine, you may notice that you feel especially fatigued. Nothing feels quite as good as laying down and going to sleep after a day in the sun, right? But why is that? Believe it or not, sun exposure itself is not what makes you feel tired. Instead, you may feel fatigued due to the side effects of spending a long day in the sun sweating and being active. Dehydration is the main cause of feeling exhausted after spending time out in the sun due to the depletion of electrolytes which can make you feel fatigued, lightheaded and even nauseous.

Common Symptoms of Dehydration

Dehydration cases are very common during the summer months. Our bodies require water to function properly, but sweating in the sun can quickly deplete your body of the water it needs. If you’re not adequately hydrating while spending time outdoors, you can quickly become severely dehydrated which can lead to feeling fatigued and disorientated. Common symptoms of dehydration include:

  • Dizziness
  • Fatigue
  • Feeling lightheaded
  • Trouble balancing
  • Dry mouth
  • Dark urine

Tips for Staying Safe While Spending Time in the Sun This Summer

If you’re planning on spending a long day in the sunshine, it is important to prepare your body. Dehydration can happen quickly and can make you feel extremely fatigued and disorientated. Hydrating well before you leave the house is critical to ensuring your body is fueled for the day ahead. Bringing plenty of water with you and sipping throughout the day will help prevent symptoms of dehydration. Always be sure to eat throughout the day and refuel regularly with water and electrolytes. You may not think you’re exerting much energy while sunbathing, but your body is working hard to stay cool, so it is important to fuel your body appropriately.
