• Stay Hydrated: Drink plenty of water throughout the day. Consider having a water bottle on your desk and make a habit of refilling it regularly.

• Healthy Snacks: Keep a stash of healthy snacks like nuts, seeds, fresh fruits, and yogurt at your desk. This will help you avoid unhealthy snack options when you feel hungry between meals.

• Regular Exercise: Incorporate mini-exercise routines in your workday. This could be a short walk, stretching exercises, or even desk yoga. Consider standing desks or under-desk exercise equipment, like a pedal exerciser.

• Meditation and Mindfulness: Incorporate short meditation or mindfulness sessions in your day. This can help reduce stress and increase focus. There are many apps available that can guide you through short mindfulness exercises.

• Balanced Meals: Try to have a well-balanced meal for lunch. It should include a mix of protein, carbs, and a variety of vegetables.

• Supplements: Depending on your personal needs and advice from a healthcare provider, consider supplements. Common ones include a multivitamin, vitamin D, omega-3 fatty acids, or probiotics. Remember that supplements should not replace a balanced diet but can help fill gaps in nutrition.

• Regular Breaks: Take short, regular breaks throughout the day to rest your mind and avoid burnout. This can be a quick walk, a short stretch, or even just looking away from your screen for a few minutes.

• Adequate Sleep: Ensure that you're getting enough sleep every night. Poor sleep can lead to reduced productivity, poorer decision-making, and overall lower work satisfaction.

• Vision Care: If you work on a computer, be mindful of your eye health. Follow the 20-20-20 rule – every 20 minutes, look at something 20 feet away for 20 seconds. There are also eye drops available for dry or tired eyes.

• Avoid Caffeine Overload: While one or two cups of coffee can help with alertness, too much caffeine can lead to jitteriness, increased heart rate, and trouble sleeping. Try to limit your intake and consider caffeine-free alternatives like herbal teas.

• Regular Check-ups: Regular health check-ups can help catch potential health issues early. Consider getting a comprehensive annual check-up.

Remember, changing habits can be difficult and take time. Start with a few manageable changes and build up as they become a part of your routine. Always consult with a healthcare provider before starting any new health routine or supplement regimen.
