Why does tanning make you tired

You're dehydrated. Another big reason why you're wiped after a beach day could be plain old dehydration. A study published in the Journal of Nutrition found that even mild dehydration can be enough to alter your mood, including making you feeling fatigued. It's hard enough to remember to stay hydrated when you're working at a desk all day, but it can be even more difficult to actually drink enough water when you're baking in the heat all day.

There's no exact amount of water that's right for everyone the eight glasses a day thing is a myth , but you should still up your water intake when you're in the sun to prevent dehydration — and, possibly, feel more alert later on. You're red as a lobster. If you happened to get a sunburn during the day, that could make it even harder for your body to regulate its temperature and stay hydrated.

This also makes it harder for you to sweat , which is all the more reason to prevent getting sunburned in the first place. Something bigger is off with your body. However, it's important to remember there's a big difference between normal fatigue at the end of an active day and actual heat exhaustion, which can become an emergency. But if you don't have any of those other symptoms and just feel a bit sleepy, you probably don't have heat exhaustion. In that case, there's nothing you can really do to feel less tired after a day in the sun besides getting some rest — and trying not to spend so much time in the sun the next day.

If you're concerned about feeling knocked out all the time not just after a day at the beach no matter how much rest you get, that's worth checking in with a doctor about.

It could be a sign of a bigger issue, such as a sleep disorder. At the end of the day, this is just another reason to be smart about your sun exposure, and remember that you don't have to spend a ton of time outside if you're more comfortable resting somewhere cool and dark — like, you know, your bed.

Plus, I offer some advice on how to keep your energy levels up when the weather is that bit warmer. While we tend to feel happier and more energetic when the sun shines, as the saying goes, it is possible to have too much of a good thing, and this is very true when it comes to the sun and your energy levels. Sunshine can boost your vitamin d levels , as well as your serotonin levels — the body's happy hormone, but too much sun can actually leave you feeling sleepy, lethargic, sluggish and drained of energy.

So, why exactly do these make you tired after spending a day in the sun? Below I take a closer look at each and offer my advice on what you can do to avoid feeling so tired after being in the sun. When the weather is very warm the body loses extra fluids through sweat. If we then fail to replace these lost fluids, we put ourselves at risk of dehydration.

Some key symptoms of dehydration to look out for include: dry mouth, headaches, dark urine, feeling thirsty, feeling light headed and not needing to go to the toilet very often. Another key symptom of dehydration that people are less aware of, however, is low energy levels. A study run by the Natural Hydration Council found that 1 in 10 cases of tiredness and fatigue can be attributed to dehydration.

Dehydration can cause blood pressure to drop and, as a result, blood flow to the brain decreases. This can then lead to tiredness and fatigue. On top of this, dehydration can disrupt sleep as it makes the nose and throat drier and more prone to irritation and snoring.

Dehydration may also affect the sleep hormone melatonin and, as a result, the circadian rhythm can be thrown of balance and it then becomes harder to fall asleep. Children, older people and people with underlying health conditions such as diabeties are particularly at risk of dehydration, though during hot weather everyone should be aware of the issue.

That's because at this time there is often an array of sugary treats on offer, from Mr Whippy 99's to fizzy juice and salty appetizers. These are, unsurprisingly, lacking in essential nutrients that could help keep our energy levels up. Magnesium, for example, is needed to form and store energy meaning a deficiency in the mineral could lead to fatigue.

Sugary foods can cause additional problems as they may cause our energy levels to spike rapidly and then drop. So, even though they may help your energy levels initially, this isn't sustainable.

In summer there is ample opportunity to spend time in the sun with friends and family but, with so many tempting and often unhealthy! Join Now. Whilst lazing around on a deck chair or reading your book is enjoyable, it means that the body is not moving and this too can leave us feeling tired. Any exercise, be it minimal or strenuous, helps boost our energy levels. It releases positive, energy-improving hormones, for example, which help to ease any feelings of tiredness.

A lack of exercise can, therefore, make us tired. If you must be outside then, seek shade, which can help you from overheating and feeling drained.
