We go to the beach to relax, but then the beach makes us more tired?
It is a phenomenon that is so routine we almost don’t question it: you go to the beach excited and happy to soak up some sun and swim and by late afternoon you are completely exhausted. Even if you have barely moved, it is likely that you will find yourself tired after spending time at the beach. But what is it about the beach that causes this enhanced tiredness? The sun? The air? The sound of the ocean? There are many urban myths about the effects of being on the beach, but what does science say?
Presently, most research has debunked the idea that there is something special about the air (as nice as sea air can be) or sand that makes you tired. But deeper looks at the impact of sunlight have actually revealed some interesting facts. For one, when you’re on the beach you’re exposed to a lot of direct sunlight. That sunlight evaporates small amounts of water in your body. This coupled with a change in body temperature then triggers a reaction from your brain that can make the body tired or cause a mood swing. This is part of why it is often recommended you wear a hat or make use of an umbrella to reduce or filter the amount of direct sunlight that is hitting you while on the beach.
It is also important to remember that being in the sun at the beach your body experiences chemical changes. Some are actually good, like the useful vitamins sunlight can provide the body with. However once you go beyond that beneficial small dosage of sun, you get into the dangerous territory of sunburn, aging, and yes- tiredness.
So it would seem it is all the sun’s fault. But lets not so easily discredit that mesmerizing sound of the ocean and the general objective of many beachgoers to completely relax. When you combine those with the powerful sun, going to the beach is a recipe for tiredness.
