Summer is the perfect time to clean up your diet. Not only will you look great for swimsuit season, but detoxing your system and getting rid of heavy food in your diet will give you more energy and keep you feeling good all summer long. Try to incorporate fresh summer produce into your diet such as strawberries, avocados, green beans, summer squash, and melons. Mike Clancy, a certified nutritionist and personal trainer in New York City, says that "Fruit and summer go hand-in-hand. Fruits and veggies are a summer favorite because they contain so many nutrients, vitamins, and minerals that keep you feeling energetic, yet satisfied, for hours and they contain fiber, which keeps the stomach feeling full and the digestive organs healthy. Many fruits and vegetables also contain water, which makes these natural foods an easy choice for hydration and satisfaction."

Speaking of water, it is important to drink enough water during summer months when it is easy to get dehydrated. "Drink an extra 20 ounces of water a day -- it's important to stay hydrated during the summer. If you don't have enough water in your body it can lead to a sluggish physical state, headaches and migraines, and lethargy. All of these things can me you more irritable and frustrated with minor things," says Mentore.

"It's easy to lose touch with close friends and family throughout the year, but isolation can and will dampen anyone's mood. So, take the time to reach out to old friends and family for a lunch date or a fun evening out," says mental health and relationship expert, Rhonda Richards Smith. Summer vacations and long weekends are the perfect opportunity to reach out to friends and family around you and re-connect. Find new activities that you can all participate in together or bond over old traditions and memories.

"One of the most important aspects of health is social interaction. Bring friends together and connect with your friends and family while participating in group-related activities. This is a great way to focus on having good, clean fun to de-stress from your everyday problems that may overwhelm you from time-to-time," says Clancy.

Sleep deprivation is not only bad for your health, but it can put you in a funk. Fitness expert and author Jenn Zerling stresses the importance of getting a good night's sleep during summer months: "The days are longer during summer time so bed time is generally pushed to a later hour. Unfortunately, the workdays begin at the same time. This leaves some people with less sleep each night, which can negatively affect one's mood the next day."

Make sure you sleep at least 7 hours a night, but watch out for over sleeping. If you get too much sleep, it will only make you more tired and leave you feeling grumpy. Find the perfect balance and you will have energy to last throughout your entire day.

Taking on a new activity or hobby will stimulate your brain and boost your mood through the excitement of a new challenge, meting new people, and working towards a goal. "Some activities to take on include learning how to sail, surf, play tennis, salsa dance, or simply take an art class or acting class. This will spice up your life a bit from daily monotony," says Zerling.

Summer can be the perfect opportunity to get active with a new sport. "With sports like basketball, tennis, or soccer we are able to look past the physical strain it puts on us to enjoy the game. Find a sport you are fond of or good at and try playing at least three times a week. This will keep you active and more likely to continue after summer is over," says Bruce Schlagel, CEO of Advanced Exercise Equipment.
