6. Muscle Cramps
Muscle cramps may be a sign of dehydration. Cramps are particularly common when dehydration is caused by excessive sweating.
Interestingly, sweating can result in a significant loss of both fluid and sodium, which is an electrolyte that plays a role in muscle contractions.
For this reason, adequate hydration is especially important during strenuous exercise or exercise in high temperatures.
Summary: Fluid and sodium depletions can lead to muscle cramps. Drinking water is particularly important during strenuous exercise.
7. Decrease in Blood Pressure
Low blood pressure can be a symptom of dehydration (22).
Interestingly, low blood pressure might make you feel light-headed or dizzy when you go from lying down to standing up (24).
That's because your heart has to pump faster and harder to get blood to the brain when there is less fluid in the body. When you stand up, it may take a few seconds for blood to get to the brain from the lower limbs.
What's more, low blood pressure can make you feel weak and tired.
Nevertheless, a small drop in blood pressure is relatively harmless and usually remedied by drinking water (25).
On the other hand, severe dehydration can lead to dangerously low blood pressure. Symptoms like blurred vision, nausea and fainting could indicate very low blood pressure that requires medical attention (24).
Summary: Dehydration can cause a drop in blood pressure, which might make you feel light-headed, weak and tired. Severe dehydration can cause dangerously low blood pressure that requires medical attention.
8. Rapid Heart Rate or Heart Palpitations
Dehydration can cause a rapid heart rate or heart palpitations. Palpitations give you the feeling that your heart is jumping or skipping a beat.
Interestingly, these abnormalities are a result of the heart attempting to compensate for the lack of fluid in the body.
When there's not enough fluid in your body, it decreases the volume of blood in your blood vessels. Your body then works hard to deliver enough blood to your organs by increasing its heart rate, pumping blood more quickly throughout your body (5, 26).
When this happens, you might feel your heart racing, fluttering or pounding extra hard.
Fortunately, in most cases of dehydration, this increase in heart rate effectively makes up for the low blood volume. Even with less blood pumping through the body, the organs and tissues are able to receive what they need.
However, as dehydration becomes more severe, the heart becomes less effective at compensating for the lack of fluid. If the heart is unable to get blood to the organs, they will eventually shut down.
Keep in mind that dehydration is not the only condition that affects heart rate. Rapid heart rate or palpitations can also indicate a more serious medical condition.
That being said, if your heart rate does not return to normal after drinking water, you should consult a medical professional.
Summary: A lack of fluid in the body decreases blood volume. The heart makes up for the lack of blood volume by working harder and faster to pump blood throughout the body.
9. Irritability or Confusion
Dehydration can have a significant effect on brain function.
Furthermore, brain function can deteriorate significantly as dehydration becomes more severe. Severe dehydration can cause confusion and incoherence (29).
In fact, confusion and even delirium are common symptoms among older adults who are dehydrated. Older adults are particularly susceptible to becoming dehydrated due to their sense of thirst declining with age (30, 31, 32).
Conversely, drinking plenty of water has a positive effect on mental clarity and brain function. In fact, both children and adults have been found to perform tasks better when they are well hydrated (33, 34, 35).
In one study, children who were given additional water to drink had improved short-term memory and performed better in school (33).
Overall, it appears that hydration status can have a significant impact on mental performance.
Summary: Dehydration can negatively affect brain function and cause symptoms like moodiness, anxiety, decreased concentration and confusion.
10. Serious Complications and Organ Failure
Severe dehydration can lead to very serious complications.
Every organ in the body requires fluid to function properly. If dehydration becomes critical, organs will begin to shut down.
In fact, a severe loss of body fluid can lead to shock, which is a potentially fatal condition (36).
Shock occurs when the volume of blood becomes so low that the brain and other organs are not able to receive the oxygen they need (37).
Moreover, shock can cause complications like loss of consciousness, brain damage, kidney failure and heart attack. If shock is not treated immediately, it will result in death (38).
That being said, shock is a rare consequence of dehydration that only occurs with an extreme loss of body water. It is most likely to come about when fluid is lost through trauma, severe burns or prolonged vomiting and diarrhea.
Summary: Extreme dehydration can cause shock and organ failure. This level of dehydration can be fatal if not treated immediately.
How to Prevent Dehydration
The key to preventing dehydration is to drink plenty of water throughout the day, along with other beverages like unsweetened coffee and tea.
Interestingly, water-rich foods like fruits and vegetables also contribute to hydration.
However, there's no magic amount of fluid you should drink every day to stay hydrated (39).
Fluid requirements vary from person to person and are affected by activity level, amount of sweat and climate (40).
Nevertheless, here are some tips to stay hydrated:
- Drink when you are thirsty: For most people, thirst is a reliable indicator that your body needs water. If you feel thirsty, drink water (1).
- Drink plenty of water before exercising: It's important to be properly hydrated before you start exercising, particularly if you are going to be active in the heat.
- Replace fluids lost through sweat: If you sweat a lot, you will need to drink extra water to replace lost fluids. In this case, you may need to drink more than your thirst demands (12).
- Keep tabs on the color of your urine: The color of your urine is a good indicator of your hydration status. Drink enough water so that your urine maintains a pale yellow color.
- Replace fluids lost through vomiting or diarrhea: Sip on liquids or ice chips if you are experiencing vomiting or diarrhea. If you are unable to keep fluids down for more than 24 hours, seek medical attention.
Summary: In order to prevent dehydration, drink when you are thirsty and replace fluids lost through sweat or illness.
The Bottom Line
Symptoms of dehydration range from thirst, in the case of mild dehydration, to organ failure when dehydration is severe.
While most cases of dehydration can be easily remedied by drinking water, more severe dehydration will likely require medical attention.
Drinking plenty of fluids can prevent dehydration and its side effects.
Furthermore, staying properly hydrated may have additional benefits, such as boosting your mood, fighting fatigue and improving memory and concentration.

Jean-Marc Neveu and Olivier Civil never expected to find themselves battling against disposable mask pollution.
When they founded their recycling start-up Plaxtil in 2017, it was textile waste they set their sights on. The project developed a process that turned fabrics into a new recyclable material they describe as "ecological plastic."
Mounting Piles of Waste<p>It is not only the streets of Chatellerault where pandemic pollution is piling-up, but also the world's beaches and oceans. Once there, they can take up to 450 years to degrade and disappear.</p><p>Esther Röling, co-organizer of the annual Adventure Clean Up Challenge held on Hong Kong Island, has seen this waste firsthand. In October the sports challenge pitted teams against one another in a competition to remove trash from 13 hard-to-reach coastal areas around the city.</p><p>They find tons of both disposable and reusable masks, said Röling. "You wonder how it ended up there. Was it just thrown on the ground? Or was it in a garbage bag that broke open?"</p><p>Almost 10,000 kilometers away in Antibes on the sunny French Riviera, it's a similar picture. For the past few months, divers and clean-up volunteers working with an ocean clean-up non-profit called Operation Mer Propre have been collecting an increasing number of masks found on land and in the sea.</p><p>"Since the beginning of the lockdown when we started to count, we've reached 800, 900, [and now in total] 1000 masks," said co-founder Joko Peltier. </p><p>According to <a href="https://unctad.org/news/growing-plastic-pollution-wake-covid-19-how-trade-policy-can-help" target="_blank">UN estimates</a>, up to 75% of all coronavirus-related plastic could end up as waste in oceans and landfills.</p>
The Limits of Recycling<p>Yet not all are convinced the recycling of this waste is possible on a global scale. </p><p>"What those citizen groups are doing is really beneficial but once they collect it, it should just go to a landfill or an incinerator. They shouldn't necessarily expect it to get recycled," said Jonathan Krones, an industrial ecologist and visiting assistant professor of environmental studies at Boston College.</p><p>That's because mask recycling programs like Plaxtil are few and far between and most don't have the benefit of a readily adaptable production process. </p><p>Even in countries with solid recycling infrastructure, he says, the system is designed to separate out specific types of waste like bottles or cardboard.</p><p>"I imagine that it would be technically feasible to develop a separation process to filter out masks, but there simply aren't enough of them to make that economical," he said.</p><p>Collection is a big hurdle, he adds. Since each mask only weighs a fraction of a gram and they're scattered on roads or mixed with other trash, it is difficult and costly. </p><p>"You need a lot of raw material of the right quality to make investing in the recycling technology and the recycling system worthwhile," he said.<span></span><br></p>
Hemp, Sugar Cane and Sustainable Alternatives<p>Some projects are instead addressing the material used to make masks.</p><p>French company Geochanvre have created a mask made primarily from hemp, while in Australia, researchers at the Queensland University of Technology are experimenting with a disposable product made from agricultural waste. </p><p>Biodegradable options are exciting alternatives to reduce the fossil fuels needed for the creation of plastic-based masks, said Krones, but they don't absolve the wearer from the responsibility of what happens afterwards. </p><p>Bio-based masks often need their own composing solutions, he explains, because in landfill they can produce high amounts of the greenhouse gas methane when anaerobic bacteria feeds on the organic material. Methane is known to be significantly more potent than carbon dioxide.</p><p>"I think as long as we have in our mind that we want to have disposability, we're going to have to wrestle with a variety of different sorts of environmental tradeoffs," he said, adding that reusable, fabric masks are the best option available to most people.</p><p>Precimask is developing a clear face covering with an optional visor made from hard plastic, designed to be long-lasting.<br></p><p>Air enters either side of the cheeks through a technology normally found in pool filters and car exhaust systems, said company spokeswoman Juliette Chambet.</p><p>"We wanted to make ceramic-based filters that would be washable and cleanable, which would allow them to be reused as many times as desired without having to buy a new consumable or produce waste," she said. </p><p>Ultimately, encouraging mask wearers to think about the entire lifecycle of a mask is key, explains Neveu. </p><p>"We want people who put on the masks to realize that they are also responsible for the waste, he said. "It's not inevitable that this [pandemic] will become an environmental catastrophe.</p><p><em>Reposted with permission from </em><em><a href="https://www.dw.com/en/covid-19-recycling-pollution-trash-pandemic/a-55707817" target="_blank">Deutsche Welle</a>.</em><a href="https://www.ecowatch.com/r/entryeditor/2649032193#/" target="_self"></a></p>
