How to stay healthy at a music festival

Here are seven top tips to help you have a happy - and healthy - music festival season:

1. Stay hydrated

Mild dehydration can cause headaches, poor concentration, tiredness and light-headedness. If you're more severely dehydrated, you can experience palpitations, breathing problems, dizziness, confusion or even loss of consciousness.

The European Food Standards Agency (EFSA) recommends that for the average adult, fluid intake should be about 1.5 litres a day for women and 2 litres for men. In addition to that, it's recommended that another half litre of fluid come from foods. However, if you're exercising you may lose as much as a litre of fluid an hour, although that varies dramatically depending on how energetically you're dancing, how much you sweat and how hot it is.

Do be aware that, while tea and coffee in moderation can contribute to your fluid intake, all alcohol is dehydrating. As a rule of thumb, if your urine looks dark rather than pale straw-coloured, you need more fluid.

And while you may think it's impossible to drink too much water, there is a rare but serious complication of fluid overload, called hyponatraemia. Some recreational drugs can make you more prone to this.

Student mental health: how to tell if your child is depressed at university

University can be an exciting time in a young person's life - for many it marks the first step into independent living, and a time to explore new opportunities. However, this exciting life change can also come with challenges, both physical and emotional.

Exercise and physical activity

Doing regular physical activity can make people feel good about themselves and it can have a number of benefits for health. For example, it reduces the risk of developing heart disease, stroke, high blood pressure, many cancers, type 2 diabetes and 'thinning' of the bones (osteoporosis). Regular physical activity also helps to control weight and ease stress. Ideally, the aim should be at least 30 minutes of moderate-intensity physical activity on at least five days of the week but even 10 minutes is better than nothing. You should aim to do at least a couple of sessions of muscle-strengthening activities per week as well.

2. Rest and recharge

You may want to make the most of every minute at a festival. But being overtired can take all the fun out of it - you're hardly going to enjoy yourself if you have a headache and can't concentrate.

As with exercising, slow-burn carbohydrates can keep your energy levels up. You may think it will be easier to sleep amid the noise of a festival at night if you have alcohol on board, but you'd be mistaken. Being drunk may make it easier to get to sleep, but your sleep pattern will be disturbed and won't refresh you in the same way. You're also more likely to wake early (probably needing a trek to the communal loos) and find it difficult to get back to sleep.

Some people find napping during the day gives them an energy boost. For others it's a recipe for poor sleep the next night.

3. Give yourself space

Music festivals are known for their large, energetic crowds. However, being hemmed in by so many partygoers can feel overwhelming for people with claustrophobia.

Claustrophobia is extremely frightening, and can come on in seconds. Alcohol and particularly recreational drugs make you much more prone to panic attacks and claustrophobia - just because other people are indulging doesn't make them a good idea.

Symptoms include an intense feeling of anxiety, thumping heart, shortness of breath, dry mouth, sweaty palms, feeling hot and cold, chest pain, feeling sick or dizzy and sometimes pins and needles in your hands and around your mouth.

In the short term, focusing on your breathing - taking very slow, deep breaths can help. Over-breathing (hyperventilation) is a natural response to very high adrenaline levels that accompany claustrophobia or panic attack. This makes you want to breathe rapidly, which in turn can result in light-headedness and dizziness from too much oxygen and too little carbon dioxide in the system. You may also want to get out of the situation as soon as possible.

However, be aware that avoiding a situation that causes symptoms of anxiety can make the problem worse in the long term, as you end up restricting your life more and more. If you suffer from regular panic attacks or claustrophobia, see your doctor about possible treatment.

4. Fuel up

The best festivals involve lots of dancing - and energetic dancing takes as much energy as marathon running.

Slow-burn carbohydrates are the body's preferred energy source during high-intensity activity - wholemeal pasta, potatoes and some fruit and vegetables are ideal. Protein helps to rebuild muscle as well as being one of the most effective forms of food for staving off hunger. White meat, fish, eggs and dairy products are great sources of protein. If you're vegan, think soy, quinoa, Quorn®, hummus or rice and beans.

5. Protect your ears

Exposure to loud noise increases your chance of age-related hearing loss (presbyacusis) in later life. As far as the average festival-goer is concerned, old age seems a lifetime away. However, chances of developing this type of hearing loss increases as early as age 40.

Tinnitus, a distressing and persistent ringing in the ears, can be brought on by exposure even to short bursts of very loud noise. It's never too early to start protecting your ears from loud noise - earplugs are as essential a part of festival life as the tent and the spare supply of loo roll.

6. Keep safe in the sun

It can be easy to forget when you're having fun in the sun, but excess sun and heat exposure can be harmful to your body.

Sunburn is an obvious one - keep a hat to hand at all times, apply sunscreen regularly and don't give in to the temptation to go shirtless.

Heat exhaustion causes extreme tiredness, profuse sweating, light-headedness and being sick.

The solution is getting out of the heat, resting and drinking plenty of fluids. Heatstroke is a more serious complication - your body loses the ability to cool itself and becomes dangerously overheated. Symptoms of heatstroke include confusion, severe headache, dizziness or fainting, muscle cramps, intense thirst and rapid shallow breathing. This is always a medical emergency.

7. Look after your feet

Many people suffer from swollen legs. For those with long-term health problems, this can be a warning sign of heart failure. But all too often it's caused by sitting with the legs down for long periods - like on a long flight. A similar (although usually milder) issue arises if you stand still for too long.

Standing still for too long means you don't use the muscle pumps in your calves that normally help pump blood around the body and back to the heart. Since fluid has to battle against gravity to get back up the legs when you're standing, this can lead to fluid accumulating, causing tired, achy and swollen lower legs.

There are two obvious solutions:

Keep your muscle pumps working by exercising your legs - either by walking or dancing or even by tensing the calf muscles regularly when you're standing or walking up and down on the spot.

Use gravity to get the fluid out of the legs - this involves keeping your legs up, ideally above the level of your heart. Lying flat on the ground with your legs propped on a pillow - or a rucksack - will help relieve the swelling and aching.
